    The focus of this study was addressed to investigate the potentiality of HyperSpectral Imaging (HSI) in the monitoring of commercial consolidant products applied on wood samples. Poplar (Populus Sp.) and walnut (Juglans Regia L.) were chosen for the consolidant application. Both traditional and innovative products were selected, based on acrylic, epoxy and aliphatic compounds. Wood samples were stresses by freeze/thaw cycles in order to cause material degradation. Then the consolidants were applied under vacuum. The samples were finally artificially aged for 168 hours in a solar box chamber. The samples were acquired in the SWIR (1000-2500 nm) range by SISUChema XL™ device (Specim, Finland) after 168 hours of irradiation. As comparison, color measurement was also used as economic, simple and noninvasive technique to evaluate the deterioration and consolidation effects on wood. All data were then processed adopting a chemometric approach finalized to define correlation models, HSI based, between consolidating materials, wood species and short time ageing effects.

    This report focuses on work completed on DE-NE0000667, Self-Consolidating Concrete for Modular Units, in connection with the Department of Energy Nuclear Energy Enabling Technologies (DOE-NEET) program. This project was completed in the School of Civil and Environmental Engineering at the Georgia Institute of Technology, with Westinghouse Corporation as the industrial partner. The primary objective of this project was to develop self-consolidating concrete (also termed “self-compacting concrete” or SCC) mixtures so that concrete placement can be made into steel plate composite (SC) modular structures without the need for continuous concrete placement. As part of the research, SCC mixtures were developed and validated to ensure sufficient shear capacity across cold-joints, while minimizing shrinkage and temperature increase during curing to enhance concrete bonding with the steel plate construction found in modular units. The SCC mixtures developed were able to carry shearing forces across the cold-joint boundaries. This “self-roughening” was achieved by adding a tailored fraction of lightweight aggregate (LWA) to the concrete mix, some of which raised to the surface during curing, forming a rough surface on which subsequent concrete placements were made. The self-roughening behavior was validated through three sets of structural tests. Shear friction on small-scale specimens with cold joints was assessed using varying fractions of LWA and with varying amounts of external steel plate reinforcement. The results show that the shear friction coefficient, to be used with the provisions of ACI 318-14, Section 22.9, can be taken as 1.35. Mid-scale beam tests were completed to assess the cold-joint capacity in both in-plane and out-of-plane bending. The results showed that the self-roughened joints performed as well as monolithic joints. The final assessment was a full-scale test using a steel composite module supplied by Westinghouse and similar in construction to

    The Savannah River Technology Center (SRTC) is Providing technical support for start-up and operation of the Consolidated Incineration Facility. This support program includes a series of pilot incineration tests performed at the Environmental Protection Agency`s (EPA`s) Incineration Research Facility (MF) using surrogate CIF mixed wastes. The objectives for this test program included measuring incinerator offgas particulate loading and size distributions as a function of several operating variables, characterizing kiln bottom ash and offgas particulates, determining heavy metal partition between the kiln bottom ash and incinerator stack gas, and measuring kiln organics emissions (particularly polychlorinated dioxins and furans). These tests were designed to investigate the effect of the following operating parameters: Incineration Temperature; Waste Feed Rate; Waste Density; Kiln Solids Residence Time; and Waste Composition. Tests were conducted at three kiln operating temperatures. Three solid waste simulants were burned, two waste mixtures (paper, plastic, latex, and PVC) with one containing spiked toxic organic and metal compounds, and one waste type containing only paper. Secondary Combustion Chamber (SCC) offgases were sampled for particulate loading and size distribution, organic compounds, polychlorinated dibenzo[p]dioxins and polychlorinated dibenzofurans (PCDD/PCDF), metals, and combustion products. Kiln bottom ash and offgas particulates were characterized to determine the principal elements and compounds comprising these secondary wastes.

    This report outlines the development of a self-consolidating concrete (also termed “self-compacting concrete” or SCC) so that concrete placement can be made into steel plate composite (SC) modular structures without the need for continuous concrete placement. As part of the research, SCC mixtures were developed and validated to ensure sufficient shear capacity across cold-joints, while minimizing shrinkage and temperature increase during curing to enhance concrete bonding with the steel plate construction found in modular units. The self-roughening concrete produced as part of this research was assessed in SC structures at three scales: small-scale shear-friction specimens, mid-scale beams tested in in-plane and out-of-plane bending, and a full-scale validation test using an SC module produced by Westinghouse as part of the Plant Vogtle expansion. The experiments show that the self-roughening concrete can produce a cold-joint surface of 0.25 inches (6 mm) without external vibration during concrete placement. The experiments and subsequent analysis show that the shear friction provisions of ACI 318-14, Section 22.9 can be used to assess the shear capacity of the cold-joints in SC modular construction, and that friction coefficient of 1.35 is appropriate for use with these provisions.

    Subsidence and settlement are phenomena that are much more destructive than generally thought. In shallow land burials they may lead to cracking of the overburden and eventual exposure and escape of waste material. The primary causes are consolidation and cave-ins. Laboratory studies performed at Los Alamos permit us to predict settlement caused by consolidation or natural compaction of the crushed tuff overburden. We have also investigated the shear failure characteristics of crushed tuff that may lead to subsidence. Examples of expected settlement and subsidence are calculated based on the known geotechnical characteristics of crushed tuff. The same thing is done for bentonite/tuff mixes because some field experiments were performed using this additive (bentonite) to reduce the hydraulic conductivity of the crushed tuff. Remedial actions, i.e., means to limit the amount of settlement, are discussed. We finally discuss our field experiment, which studies the influence of subsidence on layered systems in general and on biobarriers in particular. The share of the produced cavities is compared with cavities produced by idealized voids in an idealized environment. Study of root penetration at subsidence sites gives us an indication of the remaining degree of integrity. 30 refs., 24 figs., 19 tabs.

    The most effective post-remission treatment to maintain complete remission (CR) in adults aged between 46 and 60 years with acute myeloid leukaemia (AML) is uncertain. Previously untreated patients with AML in CR after induction chemotherapy with daunorubicin and cytarabine were randomized between two intensive courses of consolidation therapy containing high-dose cytarabine, combined with amsacrine or daunorubicin and a standard consolidation and maintenance therapy containing standard dose cytarabine and daunorubicin. One hundred fifty-eight CR patients were assigned to the intensive group and 157 patients to the standard group. After a median follow-up of 7.5 years, the 4-year survival rate was 32 % in the intensive group versus 34 % in the standard group (P = 0.29). In the intensive group, the 4-year relapse incidence was lower than in the standard group: 55 and 75 %, respectively (P = 0.0003), whereas treatment-related mortality incidence was higher: 22 versus 3 % (P < 0.0001). Two intensive consolidation courses containing high-dose cytarabine as post-remission treatment in patients with AML aged between 46 and 60 years old did not translate in better long-term outcome despite a 20 % lower relapse incidence. Better supportive care and prevention of treatment-related complications may improve the overall survival after intensified post-remission therapy in this age group.

    Conscious memory for a new experience is initially dependent on information stored in both the hippocampus and neocortex. Systems consolidation is the process by which the hippocampus guides the reorganization of the information stored in the neocortex such that it eventually becomes independent of the hippocampus. Early evidence for systems consolidation was provided by studies of retrograde amnesia, which found that damage to the hippocampus-impaired memories formed in the recent past, but typically spared memories formed in the more remote past. Systems consolidation has been found to occur for both episodic and semantic memories and for both spatial and nonspatial memories, although empirical inconsistencies and theoretical disagreements remain about these issues. Recent work has begun to characterize the neural mechanisms that underlie the dialogue between the hippocampus and neocortex (e.g., "neural replay," which occurs during sharp wave ripple activity). New work has also identified variables, such as the amount of preexisting knowledge, that affect the rate of consolidation. The increasing use of molecular genetic tools (e.g., optogenetics) can be expected to further improve understanding of the neural mechanisms underlying consolidation.

Based on the soil characteristics analysis on the archaeological sites, experimental studies were conducted on the consolidation effect of the BS-10 consolidation material on the archaeological sites of adobe and rammed earth. The results showed the following:, after consolidation, the wind erosion resistance of the soil on the archaeological sites was substantially increased, and the wind erosion modulus was reduced by 5~8 times; the soil exhibited fine grid structure and significantly reduced degree of permeability, while still maintaining the moisture exchange between inside and outside the soil; there is excellent ageing resistance; the resistance to freezing and thawing was closely related to the soil water content and had little influence in arid regions; the water resistance was improved and could satisfy the requirements for consolidating the sites in arid regions; the unconfined compressive strength was improved moderately, which was the key direction of improvement in the future, and the consolidated soil did not form duricrust on the surface and had good bonding strength with the internal parts. The BS-10 material can meet the consolidation requirements for the earthen archaeological sites in arid regions of northwest China.

    Full Text Available In this paper, we explore system dynamics as a useful approach to consolidate findings from case studies on business process change (BPC projects. We compile data from 65 BPC case studies to develop a system dynamics simulation model that helps us to investigate ‘employee morale’ as an important construct in BPC projects. We show that such simulation models consolidate the complex and often non-linear findings from BPC case studies in a way that makes it available to discourse among researchers, lecturers and students as well as BPC professionals. Thus, this paper contributes to knowledge management and learning by suggesting system dynamics as a valuable approach to illustrate and convey the complex relationships between important constructs in BPC. This paper also contributes to the domain of business process management by demonstrating the benefits of system dynamics as a way to review and consolidate the abundance of BPC case studies.

    The goal of this project is to improve the understanding of key aspects of the coupled thermal-mechanical-hydrologic response of granular (or crushed) salt used as a seal material for shafts, drifts, and boreholes in mined repositories in salt. The project is organized into three tasks to accomplish this goal: laboratory measurements of granular salt consolidation (Task 1), microstructural observations on consolidated samples (Task 2), and constitutive model development and evaluation (Task 3). Task 1 involves laboratory measurements of salt consolidation along with thermal properties and permeability measurements conducted under a range of temperatures and stresses expected for potential mined repositories in salt. Testing focused on the role of moisture, temperature and stress state on the hydrologic (permeability) and thermal properties of consolidating granular salt at high fractional densities. Task 2 consists of microstructural observations made on samples after they have been consolidated to interpret deformation mechanisms and evaluate the ability of the constitutive model to predict operative mechanisms under different conditions. Task 3 concerns the development of the coupled thermal-mechanical-hydrologic constitutive model for granular salt consolidation. The measurements and observations in Tasks 1 and 2 were used to develop a thermal-mechanical constitutive model. Accomplishments and status from each of these efforts is reported in subsequent sections of this report

    1995-11-30

    In 1991, the DOE made a decision to close the FMPC located in Fernald, Ohio, and end its production mission. The site was renamed FEMP to reflect Fernald`s mission change from uranium production to environmental restoration. As a result of this change, the inventory of strategic uranium materials maintained at Fernald by DOE DP will need to be relocated to other DOE sites. Although considered a liability to the Fernald Plant due to its current D and D mission, the FEMP DU represents a potentially valuable DOE resource. Recognizing its value, it may be important for the DOE to consolidate the material at one site and place it in a safe long-term storage condition until a future DOE programmatic requirement materializes. In August 1995, the DOE Office of Nuclear Weapons Management requested, Lockheed Martin Energy Systems (LMES) to assess the feasibility of consolidating the FEMP DU materials at the Oak Ridge Reservation (ORR). This feasibility study examines various phases associated with the consolidation of the FEMP DU at the ORR. If useful short-term applications for the DU fail to materialize, then long-term storage (up to 50 years) would need to be provided. Phases examined in this report include DU material value; potential uses; sampling; packaging and transportation; material control and accountability; environmental, health and safety issues; storage; project management; noneconomic factors; schedule; and cost.

  9. Nonlinear Finite Strain Consolidation Analysis with Secondary Consolidation Behavior

    Directory of Open Access Journals (Sweden)

    Jieqing Huang

    2014-01-01

    Full Text Available This paper aims to analyze nonlinear finite strain consolidation with secondary consolidation behavior. On the basis of some assumptions about the secondary consolidation behavior, the continuity equation of pore water in Gibson’s consolidation theory is modified. Taking the nonlinear compressibility and nonlinear permeability of soils into consideration, the governing equation for finite strain consolidation analysis is derived. Based on the experimental data of Hangzhou soft clay samples, the new governing equation is solved with the finite element method. Afterwards, the calculation results of this new method and other two methods are compared. It can be found that Gibson’s method may underestimate the excess pore water pressure during primary consolidation. The new method which takes the secondary consolidation behavior, the nonlinear compressibility, and nonlinear permeability of soils into consideration can precisely estimate the settlement rate and the final settlement of Hangzhou soft clay sample.

    Traditionally, the search for memory circuits has been centered on examinations of amnesic and AD patients, cerebral lesions and, neuroimaging. A complementary alternative might be the use of autoradiography with radioligands. Indeed, ex vivo autoradiographic studies offer the advantage to detect functionally active receptors altered by pharmacological tools and memory formation. Hence, herein the 5-HT(6) receptor antagonist SB-399885 and the amnesic drugs scopolamine or dizocilpine were used to manipulate memory consolidation and 5-HT(6) receptors expression was determined by using [(3)H]-SB-258585. Thus, memory consolidation was impaired in scopolamine and dizocilpine treated groups relative to control vehicle but improved it in SB-399885-treated animals. SB-399885 improved memory consolidation seems to be associated with decreased 5-HT(6) receptors expression in 15 out 17 brain areas. Scopolamine or dizocilpine decreased 5-HT(6) receptors expression in nine different brain areas and increased it in CA3 hippocampus or other eight areas, respectively. In brain areas thought to be in charge of procedural memory such basal ganglia (i.e., nucleus accumbens, caudate putamen, and fundus striate) data showed that relative to control animals amnesic groups showed diminished (scopolamine) or augmented (dizocilpine) 5-HT(6) receptor expression. SB-399885 showing improved memory displayed an intermediate expression in these same brain regions. A similar intermediate expression occurs with regard to amygdala, septum, and some cortical areas in charge of explicit memory storage. However, relative to control group amnesic and SB-399885 rats in the hippocampus, region where explicit memory is formed, showed a complex 5-HT(6) receptors expression. In conclusion, these results indicate neural circuits underlying the effects of 5-HT(6) receptor antagonists in autoshaping task and offer some general clues about cognitive processes in general.

    This paper presents a semi-analytical method to solve one dimensional consolidation problem by taking consideration of varied compressibility of soil under cyclic loading. In the method, soil stratum is divided equally into n layers while load and consolidation time are also divided into small parts and time intervals accordingly. The problem of one-dimensional consolidation of soil stratum under cyclic loading can then be dealt with at each time interval as one-dimensional linear consolidation of multi-layered soils under constant loading. The compression or rebounding of each soil layer can be judged by the effective stress of the layer. When the effective stress is larger than that in the last time interval, the soil layer is compressed, and when it is smaller, the soil layer rebounds. Thus, appropriate compressibility can be chosen and the consolidation of the layered system can be analyzed by the available analytical linear consolidation theory. Based on the semi-analytical method, a computer program was developed and the behavior of one-dimensional consolidation of soil with varied compressibility under cyclic loading was investigated, and compared with the available consolidation theory which takes no consideration of varied compressibility of soil under cyclic loading. The results showed that by taking the variable compressibility into account, the rate of consolidation of soil was greater than the one predicted by conventional consolidation theory.

    Full Text Available Abstract Background Extraction of premolars and retracting the anterior teeth using mini-implants and anterior retraction hooks became advent now a day. In such treatments, consolidation of arches is not done in regular practice. So, the present study is concentrated on effects of consolidation in two implant and three implant combinations of retraction and intrusion. Methods A three-dimensional FEM model of maxillary teeth and periodontal ligament housed in the alveolar bone with the first premolars extracted is generated with appropriate number of elements and nodes. The models were broadly divided into two groups according to the no. of implants. Mini-implants were placed bilaterally between the second premolar and molar at varying heights (7, 10, 13 mm in group I, and along with bilateral implants, an additional mid-implant is placed between the central incisors as group II. Brackets with 0.022 slot were placed on the teeth, 19 × 25 SS wire is placed in the brackets, an anterior retraction hook was placed at 9 mm height, and analysis was done to evaluate the stresses and displacement patterns in consolidation and non-consolidation models. Results The results showed that consolidation of the anterior teeth during intrusion and retraction shows various advantages such as less stresses on the bone, PDL, implant, teeth, and no labial flaring of the anterior teeth and three implant system, i.e., two bilateral implant at 10 mm and a mid-implant at 12 mm between the centrals has shown to be better than other models as bodily movement is observed. Conclusion Consolidation is better than non consolidation during enmasse retraction and intrusion.

    Crystalline rock and consolidated clay are both considered adequate host rocks for a high-level radioactive waste deep geological repository (HLWR). Over the extended periods of HLWR operation, long-lived radionuclides (RN) may be released from the fuel and migrate to the geo/biosphere. To predict the fate of contaminants and to assess the safety of the host rock, it is very important to determine transport parameters, as diffusion coefficients, and to relate them to the physical properties of the barriers, as connected porosity. In heterogeneous materials, it is also a major task to describe the transport at the mineral scale evaluating diffusion coefficients and mineral-specific porosities on single minerals. The main objective of this study was to determine within granite and consolidated clay, the connective porosity and mineral-specific porosities by poly-methylmethacrylate (PMMA) autoradiography method. Scanning electron microscopy and energy-dispersive X-ray analyses (FESEM/EDS) were performed in order to study the pore apertures of porous regions in greater detail and to identify the corresponding minerals. By the novel application of the nuclear ion beam technique Rutherford Backscattering Spectrometry (RBS) apparent diffusion coefficients were determined at mineral scale. Finally, the porosity results were used to evaluate the effective diffusion coefficients and retention parameters of single minerals in different granite samples and consolidated clays.

    The Gibson one-dimensional large strain consolidation theory has the very big limitation, and to meet the specific needs the Gibson theory should be constantly revised. The problems on the clay blanket cracks in the warping processing under the osmotic pressure consolidation of warping clay are studied. First of all, the finite strain consolidation theory model for seepage pressure is derived and then based on the finite strain consolidation theory the differential equation for the finite strain osmotic pressure consolidation is derived with the excess pore water pressure and pore ratio. Through the design and model tests the crack silting consolidation process is simulated, and at the same time the theory model and the consolidation partial differential equations are validated. Finally, the model test results are used to guide the field tests.%Gibson的一维大变形固结理论存在很大的局限性,为符合特定的需求,不断对Gibson理论进行修正。本文针对黏土铺盖裂缝的淤填处理问题,对渗压作用下的淤填黏土的固结机理进行了研究。首先,推导出有限应变渗压固结理论模型,再基于有限应变固结理论分别推导出以超孔隙水压力和孔隙比表示的有限应变渗压固结偏微分方程,并通过设计模型试验模拟了裂缝处淤填固结的全过程,同时对理论模型和固结偏微分方程进行了验证,最后以模型试验结果为依据指导了现场试验。

    This study is devoted to the electrical and dielectric properties of consolidated clays. A better understanding of the conduction and polarization phenomena in clays is necessary to better interpret in situ measurements in terms of water saturation and texture. An experimental study was carried out on synthetic clay samples (kaolinite and smectite) compacted with various water contents, porosities and mineralogical compositions, on a large frequency range, using three laboratory setups. The electrical properties of natural argillites (from ANDRA) were then investigated. We found that the response of the synthetic samples is mainly controlled by water content on the whole frequency range; two polarization phenomena were observed, which were related to the Maxwell-Wagner polarization and the electrical double layer polarization around the clay particles. The electrical response of argillites is more complex; it is controlled by water content but also by the microstructure of the rock. In these rocks, the electrical and dielectric anisotropies are high; anisotropy was also measured for the synthetic clays. The existing models explain the high frequency limit of the dielectric permittivity of the clayey materials, but the low frequency part of the spectra ({<=}1 MHz) needs theoretical developments.

    Using an observational sample of players of a simple online game (n > 1.2 million), we are able to trace the development of skill in that game. Information on playing time, and player location, allows us to estimate time of day during which practice took place. We compare those whose breaks in practice probably contained a night's sleep and those whose breaks in practice probably did not contain a night's sleep. Our analysis confirms experimental evidence showing a benefit of spacing for skill learning, but it fails to find any additional benefit of sleeping during a break from practice. We discuss reasons why the well-established phenomenon of sleep consolidation might not manifest in an observational study of skill development. We put the spacing effect into the context of the other known influences on skill learning: improvement with practice, and individual differences in initial performance. Analysis of performance data from games allows experimental results to be demonstrated outside of the lab and for experimental phenomenon to be put in the context of the performance of the whole task.

  8. Delayed working memory consolidation during the attentional blink.

    2002-12-01

    After the detection of a target (T1) in a rapid stream of visual stimuli, there is a period of 400-600 msec during which a subsequent target (T2) is missed. This impairment in performance has been labeled the attentional blink. Recent theories propose that the attentional blink reflects a bottleneck in working memory consolidation such that T2 cannot be consolidated until after T1 is consolidated, and T2 is therefore masked by subsequent stimuli if it is presented while T1 is being consolidated. In support of this explanation, Giesbrecht & Di Lollo (1998) found that when T2 is the final item in the stimulus stream, no attentional blink is observed, because there are no subsequent stimuli that might mask T2. To provide a direct test of this explanation of the attentional blink, in the present study we used the P3 component of the event-related potential waveform to track the processing of T2. When T2 was followed by a masking item, we found that the P3 wave was completely suppressed during the attentional blink period, indicating that T2 was not consolidated in working memory. When T2 was the last item in the stimulus stream, however, we found that the P3 wave was delayed but not suppressed, indicating that T2 consolidation was not eliminated but simply delayed. These results are consistent with a fundamental limit on the consolidation of information in working memory.

  9. Axisymmetric Consolidation of Unsaturated Soils by Differential Quadrature Method

    2013-01-01

    Full Text Available Axisymmetric consolidation in a sand drain foundation is a common problem in foundation engineering. In unsaturated soils, the excess pore-water and pore-air pressures simultaneously change during the consolidation procedure; and the solutions are not easy to obtain. The present paper uses the differential quadrature method (DQM for axisymmetric consolidation of unsaturated soils in a sand drain foundation. The radial seepage of sand drain foundation is considered based on the framework of Fredlund’s one-dimensional consolidation theory in unsaturated soils. With the use of Darcy’s law and Fick’s law, the polar governing equations of excess pore-air and pore-water pressures of axisymmetric consolidation are derived. By using DQM, the two governing equations are transformed into two sets of ordinary differential equations. Then the solutions of excess pore-water and pore-air pressures can be obtained by Rong-Kutta method. The DQM solution can be used to deal with the case of nonuniform initial pore-air and pore-water distributions. Finally, case studies are presented to investigate the behavior of axisymmetric consolidation of unsaturated soils. The convergence analysis and average degree of consolidation, the settlements in radial and vertical direction, and the effects of different initial excess pore pressure distributions are presented, and discussed in this paper.

    2008-01-01

    The problem of one-dimensional consolidation of over-consolidated saturated soil under time-dependent loading was studied based on semi-analytical method. The relevant computer code was developed by FORTRAN programming, and one-dimensional consolidation behavior of over-consolidated soil was investigated. It is shown that, unlike this described by traditional Terzaghi's consolidation theory, the rate of excess pore water pressure dissipation is different from that of settlement developing. The magnitude of load and that of pre-consolidation pressure as well as the loading rate has all significant influence on consolidation. With the increasing of pre-consolidation pressure and loading rate, the rate of consolidation increases correspondingly. However, an increase in load will slow down the consolidation rate.

    On the basis of elastic-plastic damage model of cement consolidated soil, the authors took organic contents into reasonable damage variable evolution equation in order to seek relation between the organic contents and parameters in the equation, and established the elastic-plastic damage model of cement consolidated soil considering organic contents. The results show that the parameters change correspondingly with difference of the organic contents. The higher the organic contents are, the less the valves of the parameters such as elastic modulus (E), material parameters (K, n) and damage evolution parameter (ε) become, but the larger strain damage threshold value (εd) of the sample is. Meanwhile, the calculation results obtained from established model are compared with the test data in the condition of common indoors test, which is testified with reliability.

    Coal gangue which is being used as construction and filling material must have a fairly high degree of compactness. But the compactness of coal waste appears to have been affected by its complex lithologic composition and grain size distribution. This paper discusses the relationship between the granular composition and the compactness of coal waste. The results of compacting and permeability test using coal gangue with different grain size distribution show that the main factor which affects the consolidation-compactness of coal gangue is the low proportion of fine-grain, especially silt and clay. If its content of fine-grain is increased, not only the coal gangue can achieve a high degree of consolidation under a low compacting energy, its water-stability can also be improved significantly. 3 refs., 7 figs., 3 tabs.

    Stamp forming is a rapid manufacturing technology used to shape flat blanks of thermoplastic composite material into three-dimensional components. Currently, expensive autoclave and press consolidation are used to preconsolidate blanks. This study investigates the influence of preconsolidation on final consolidation quality after stamp forming and explores the potential of alternative blank manufacturing methods that could reduce part costs. Blanks were manufactured using various blank manufacturing methods and subsequently were stamp formed. The consolidation quality both before and after stamp forming was compared, where the focus was on void content as the main measure for consolidation quality. The void content was characterized through thickness and density measurements, as well as by microscopy analysis. Results indicate that preconsolidation quality does have an influence on the final consolidation quality. This is due to the severe deconsolidation and limited reconsolidation during stamp forming. Nevertheless, the potential of automated fiber placement and ultrasonic spot welding as alternative blank manufacturing methods was demonstrated.

  18. Investigation of the Effects of Anisotropic Flow of Pore Water and Multilayered Soils on Three-Dimensional Consolidation Characteristics

    Directory of Open Access Journals (Sweden)

    Arpan Laskar

    2017-01-01

    Full Text Available Many practical engineering problems are seriously different from the assumptions which are considered for one-dimensional consolidation test and need to concentrate on three-dimensional consolidation of soil under different boundary conditions. In this study three-dimensional consolidation tests are performed with four different anisotropic flow conditions of pore water and fifteen different combinations of horizontal layered soils. Twelve different three-dimensional consolidation tests are also performed with different soils, surrounded by anisotropic vertical soil layers on two opposite sides. From these studies, it is observed that the anisotropic flow of pore water does not have any effect on initial and final surface settlement of soil but has a significant effect during the consolidation process. The anisotropic flow of pore water during the consolidation process has an immense effect on the coefficient of consolidation. Horizontal layered soil has a great effect on both surface settlement and the rate of settlement. Vertical soil layers on two opposite sides of consolidative soil have an immense effect on the horizontal movements of consolidating soil, finally affecting the resultant vertical settlement of soil. Vertical anisotropic surrounding soil layers also have an effect on the rate of consolidation settlement.

    Salt crystallization is one of the major weathering agents in porous building materials due to the crystallization pressure exerted by salt crystals growing in confined pores. The consolidation of such degraded stone materials is a crucial issue in the field of Cultural Heritage restoration.
 This contribution deals with laboratory experimentation carried out on the Neapolitan Tuff, a pyroclastic rock largely used in the Campanian architecture. Several specimens, collected from a historical quarry nearby the city of Naples, were treated with two different consolidating products: a suspension of nanosilica in water (Syton X30®) and ethyl silicate (Estel 1000®) dispersed in organic solvent (TEOS). Then, in order to assess the effectiveness of consolidation treatments, both treated and untreated samples underwent accelerated degradation through salt crystallization tests. A multi-analytical approach, including mercury intrusion porosimetry, peeling tests and point load test, was employed to evaluate the correlation between the salt crystallization and the micro-structural features of the examined tuff specimens. In addition, the calculation of the crystallization pressures was also performed in order to make a correlation between the porous structure of the tuff and its susceptivity to salt crystallization. Obtained results show that both the tested products increase the resistance of tuff to salt crystallization, although inducing an increase of crystallization pressure. Ethyl silicate, however, shows a better behaviour in terms of superficial cohesion, even after several degradation cycles.

    Scientific and technical measures to shorten outage times in longwall mining in the thin seams of the Donbass coal area are described, especially roof consolidation measures. After describing the local geological and technical conditions the author establishes a multidimensional regression equation on the basis of the influencing parameters for the purpose of predicting roof cleavage characteristics. Cleavage characteristics were found to change with the advance of longwall mining, i.e. there is an optimum period of time and an optimum efficiency range e.g. for solidification by injection. The variation with time of roof cleavage characteristics necessitates accurate timing of solidification measures in the course of operation and consideration of certain technological parameters. Methods of determining these parameters are described. The investigations have been validated by practical longwall mining operations. Factors favouring solidification with MFF-M resin as well as factors favouring roof bolting are listed.

    The rate of long-term remissions after treatment of peripheral T cell lymphomas (PTCL) with standard CHOP-like protocols is unsatisfactory. A prospective multicenter phase II trial was initiated in untreated patients with PTCL of all International Prognostic Index-risk groups, evaluating alemtuzumab consolidation in patients with complete or good partial remission after CHO(E)P-14 induction. Twenty-nine (70.7 %) of the 41 enrolled patients received alemtuzumab consolidation (133 mg in total). The main grades 3-4 toxicities during alemtuzumab therapy were infections and neutropenia with one potentially treatment-related death. Complete responses were seen in 58.5 %, partial responses in 2.4 % and 29.3 % had progressive disease. After a median observation time of 46 months, 19 patients have died, 16 of them due to lymphoma and/or salvage therapy complications. Event-free and overall survival at 3 years in the whole intent to treat population are 32.3 and 62.5 %, respectively, and 42.4 and 75.1 % in the patients who received alemtuzumab. In conclusion, application of a short course of alemtuzumab after CHO(E)P-14 induction is feasible although complicated by severe infections. A current phase III trial, applying alemtuzumab as part of the initial chemotherapy protocol to avoid early progression, will further clarify its significance for the therapeutic outcome.

    The goal of land consolidation in China is still to develop agricultural production. The study of landscapeeffects of land consolidation projects (LCPs) faces many difficulties because of the lack of government's interest anddata. This paper, taking Tianmen City of Hubei Province in Central China as an example, presents a methodology foranalyzing landscape effects of LCPs by GIS and Fragstats3.3. It describes landscape effects with indexes of PatchDensity (PD), Largest Patch Index (LPI), Landscape Shape Index (LSI), Interspersion and Juxtaposition Index (IJI),Aggregation Index (AI), and Shannon's Diversity Index (SHDI), showing more regular shape, simpler structure andless habitat diversity after LCPs. It computes ten landscape indexes of four categories of patches including CultivatedLand, Road, Water Channel, and River and Pond. The indexes show that 1) cultivated land becomes more fragmentalin patch area, less irregular in patch shape and more concentrated in block; 2) the transport capacity of roads and irri-gation and drainage capacity of water channels have been improved; 3) the landscape change of river and pond can besummarized as decreasing scale, more regular shape, reducing connectivity and diversity of the class. LCPs can facili-tate agricultural production as well as protect cultivated land and food security. However, it is doubted that the increaseof cultivated land from LCPs results from the reducing in landscape diversity of water area.

    One is the International Convention for Suppressing Acts of Nuclear Terrorism (ICSANT) and the other is amendment to the Convention on Physical Protection of Nuclear Material (CPPNM). ICSANT and CPPNM were proposed by the UN and IAEA, respectively to strengthen the international framework of nuclear security. The ICSANT was entered into force in 2007, but CPPNM amendment is pending in force because the shortage of countries who ratify it. For going into effect this convention, it needs the two-thirds of the States Parties to the CPPNM. It is not completed, yet. So, various initiatives such as nuclear security summit, GICNT, UN ministerial conference, etc. treated that those two conventions were the primary basis to strengthen the global nuclear security architecture. The Republic of Korea (ROK) continuously has made an effort to consolidate the nuclear security legislative framework since the 2010. The purpose of this paper is to provide what we did to strengthen the nuclear security legal framework and what should we do next.

    Motivational interviewing (MI) is an evidence-based intervention that has been widely recommended in clinical settings where consumer behaviour change is a goal of treatment. Training clinicians in MI, as with other translational endeavours, does not always result in changes to clinical practice. The present study compares two post-training approaches to consolidate MI skills following a training workshop. We randomly assigned 63 clinicians working in mental health or drug and alcohol services to receive either face-to-face group consolidation sessions or to access a series of online consolidation resources. We compared clinician engagement and devised a new instrument to measure clinician outcomes. Participants who completed follow-up consolidation retained knowledge, attitudes, and practices, regardless of consolidation method. Face-to-face consolidation sessions were superior to online materials in engaging participants (mean sessions attended was 2.1 (maximum possible = 3) compared to a mean of 1.38 sessions, respectively (t(61) = -2.73, P = 0.008, d = 0.72, 95% confidence interval: 0.19-1.25). Engagement to the completion of consolidation sessions was also influenced by previous training in MI. For every additional hour of previous MI training, there was a 10% increase in the odds that the participant would complete the final consolidation session.

    Full Text Available This paper concentrates on information disclosure regarding IAS 23, being included in accounting research field. It comprises an empirical study on the correlation between information published by companies in consolidated financial statements with respect to borrowing cost policies and a series of variables that characterize a firm. The objectives of this paper involve estimating and establishing an econometric model in which is assumed that disclosure index for information required by IAS 23 depends on certain elements in the form of country of origin, sales, total assets, debt ratio, ROA and ROE. International accounting literature presents a series of studies on the subject of compliance with IAS disclosure requirements. Similar with this paper, various authors considered annual reports as starting point for data gathering in their reasearch on disclosure phenomena. The criteria used for data gathering, processing and analysing have been previously used in a successful manner by important scientists who published in accounting field. The methodology used involves Disclosure Index computation, as well as SPSS data processing, analysis and interpretation of results. Results show that the model is valid, meaning that there is correlation between information disclosure with respect to IAS 23 and the analyzed variables. According to our estimated econometric model, most of the variables maintain a certain influence on disclosure as we can observe a significant correlation level between the studied elements. This research contributes to the development of both accounting field and international accounting literature, by studying borrowing costs disclosed information in relation to certain elements that best characterize the activity of a company. Although an empirical paper, it concentrates also on accounting practices, as it uses real data extracted from annual reports and consolidated financial statements.

    Decision analysis was used to rank alternative sites for a potential Consolidated Waste Capability (CWC) to replace current hazardous solid waste operations (hazardous/chemical, mixed low-level, transuranic, and low-level waste) at Los Alamos National Laboratory's Technical Area (TA)-54. An original list of 21 site alternatives was pre-screened to seven sites that were assessed using the analytical hierarchy process with five top-level criteria and fifteen sub-criteria. The top site choice is TA-63/52/46; the second choice is TA-18/36. The seven sites are as follows. TA-18/36 (62 acres) is located on Potrillo Drive that intersects Pajarito Road at the bottom of a steep grade. It has some blast zone issues on its southwest side and some important archeological sites on the southeast section. TA-60 (50 acres) is located at the end of Eniwetok Road off Diamond Drive, east of TA-3. Most of the site is within a fifty foot-deep ravine (that may have contamination in the drainage), with a small section on the mesa above. TA-63/52/46 (110 acres) lies to the north of Pajarito Road along Puye Road. It is centrally located in a brown field industrial area, with good access to generators on a controlled road. TA-46 (22 acres) is a narrow site on the south side of Pajarito Road across from TA-46 office buildings. TA-48 (14 acres) is also narrow, and is located on the north side of Pajarito Road near the west vehicle access portal (VAP). TA-51 (19 acres) is located on the south side of Pajarito Road at the top of the hill above TA-18 near the current entrance to the TA-54. TA-54 West (16 acres) is just north of the entrance to TA-54 at Pajarito Road and is close to Zone 4. Although it is near the San Ildefonso Pueblo property line, there may be adequate set-back for sight screening.

  11. Memory consolidation in sleep disorders.

    2016-09-25

    In recent years sleep-related memory consolidation has become a central topic in the sleep research field. Several studies have shown that in healthy individuals sleep promotes memory consolidation. Notwithstanding this, the consequences of sleep disorders on offline memory consolidation remain poorly investigated. Research studies indicate that patients with insomnia, obstructive sleep apnea, and narcolepsy often exhibit sleep-related impairment in the consolidation of declarative and procedural information. On the other hand, patients with parasomnias, such as sleep-walking, night terrors and rapid eye movement (REM) behavior disorder, do not present any memory impairment. These studies suggest that only sleep disorders characterized by increased post-learning arousal and disrupted sleep architecture seem to be associated with offline memory consolidation issues. Such impairments, arising already in childhood, may potentially affect the development and maintenance of an individual's cognitive abilities, reducing their quality of life and increasing the risk of accidents. However, promising findings suggest that successfully treating sleep symptoms can result in the restoration of memory functions and marked reduction of direct and indirect societal costs of sleep disorders.

  12. Deposited sediment settlement and consolidation mechanisms

    2015-10-01

    Full Text Available In order to study deposited sediment settlement and consolidation mechanisms, sediment settlement experiments were conducted using a settlement column. Based on the experimental results, sediment settlement stage definition, excessive pore pressure (EPP dissipation, and consolidation constitutive equations are discussed. Three stages, including the free settlement, hindered settlement, and self-weight consolidation settlement stages, are defined. The results of this study show that sediment settlement is mainly affected by the initial sediment concentration and initial settlement height, and the interface settlement rate is attenuated linearly with time on bilogarithmic scales during the hindered settlement and self-weight consolidation settlement stages. Moreover, the deposited sediment layer in the self-weight consolidation settlement stage experiences large strains, and the settlement amount in this stage is about 32% to 59% of the initial height of deposited sediment. EPP is nonlinearly distributed in the settlement direction, and consolidation settlement is faster than EPP dissipation in the self-weight consolidation settlement stage. Consolidation constitutive equations for the hydraulic conductivity and effective stress, applicable to large-strain consolidation calculation, were also determined and fitted in the power function form.

    It is estimated that the spent fuel storage pools at some domestic light-water reactors will run out of space before 2003, the year that the US Department of Energy currently predicts it will have a repository available. Of the methods being studied to alleviate the problem, rod consolidation is one of the leading candidates for achieving more efficient use of existing space in spent fuel storage pools. Rod consolidation involves mechanically removing all the fuel rods from the fuel assembly hardware (i.e., the structural components) and placing the fuel rods in a close-packed array in a canister without space grids. A typical goal of rod consolidation systems is to insert the fuel rods from two fuel assemblies into a canister that has the same exterior dimensions as one standard fuel assembly (i.e., to achieve a consolidation or compaction ratio of 2:1) and to compact the nonfuel-bearing structural components from those two fuel assemblies by a factor of 10 to 20. This report provides an overview of the current status of rod consolidation in the United States and a small amount of information on related activities in other countries. 85 refs., 36 figs., 5 tabs.

    Celik, Kemal

    2014-09-01

    The purpose of this study is to compare the effects of Portland cement replacement on the strength and durability of self-consolidating concretes (SSC). The two replacement materials used are high-volume natural pozzolan (HVNP), a Saudi Arabian aluminum-silica rich basaltic glass and high-volume Class-F fly ash (HVFAF), from Jim Bridger Power Plant, Wyoming, US. As an extension of the study, limestone filler (LF) is also used to replace Portland cement, alongside HVNP or HVFAF, forming ternary blends. Along with compressive strength tests, non-steady state chloride migration and gas permeability tests were performed, as durability indicators, on SCC specimens. The results were compared to two reference concretes; 100% ordinary Portland cement (OPC) and 85% OPC - 15% LF by mass. The HVNP and HVFAF concrete mixes showed strength and durability results comparable to those of the reference concretes; identifying that both can effectively be used to produce low-cost and environmental friendly SCC. © 2013 Elsevier Ltd.

    Lodestar has carried out a vigorous research program in the areas of rf, edge plasma and divertor physics, with emphasis largely geared towards improving the understanding and performance of ion-cyclotron heating and current drive (ICRF) systems. Additionally, a research program in the field of edge plasma and divertor modeling was initiated. Theoretical work on high power rf sheath formation for multi-strap rf arrays was developed and benchmarked against recent experimental data from the new JET A2 antennas. Sophisticated modeling tools were employed to understand the sheath formation taking into account realistic three-dimensional antenna geometry. A novel physics explanation of an observed anomaly in the low power loading of antennas was applied to qualitatively interpret data on DIII-D in terms of rf sheaths, and potential applications of the idea to develop a near-field sheath diagnostic were explored. Other rf-wave related topics were also investigated. Full wave ICRF modeling studies were carried out in support of ongoing and planned tokamaks experiments, including the investigation of low frequency plasma heating and current drive regimes for IGNITOR. In a cross-disciplinary study involving both MHD and ICRF physics, ponderomotive feedback stabilization by rf was investigated as a potential means of controlling external kink mode disruptions. In another study, the instability of the ion hybrid wave (IHW) in the presence of fusion alpha particles was studied. In the field of edge plasma and divertor modeling studies, Lodestar began the development of a theory of generalized ballooning and sheath instabilities in the scrape off layer (SOL) of divertor tokamaks. A detailed summary of the technical progress in these areas during the contract period is included, as well as where references to published work can be found. A separate listing of publications, meeting abstracts, and other presentations is also given at the end of this final report.

    Full Text Available Background. According to health status reports, chronic disease prevalence appears to be rising in western Alaska Native (AN people, and accurate population-based data are needed. Four cohort studies of western AN people were conducted in the Norton Sound and Yukon-Kuskokwim regions, but none have been large enough to allow reliable estimates of rates of chronic diseases and evaluate their risk factors. Objective. In this article, the methods used to combine 4 major cohort studies of rural western AN people are described and the benefits and challenges encountered in combining data and standardizing surveillance methods for these studies are discussed. Design. Tribal permission was obtained for each cohort study and the consolidated study. Data from baseline exams were directly combined or harmonized into new variables. Common surveillance methods were developed and implemented to identify incidence and risk factors for cardiovascular disease (CVD events and type 2 diabetes. Results. A cohort of 4,569 western AN participants (2,116 men and 2,453 women, aged 18–95 years, was established to study CVD and diabetes prevalence. Prospective surveillance data over an average 6.7-year follow-up can now be used to study CVD and diabetes incidence and associated risk factors in a subset of 2,754 western AN participants (1,218 men and 1,536 women who consented to initial surveillance. Conclusions. The combined cohort provides statistical power to examine incidence rates and risk factors for CVD and diabetes and allows for analyses by geographic region. The data can be used to develop intervention programmes in these populations and others.

    Full Text Available This article describes the process of land consolidations in Slovakia. Fundamental goals of land consolidation are defined in the paper. Land ownership is briefly described with emphasis on historical development. Functional reorganisation of the territory is described in detail. The authors state that this objective is in land consolidation designs, often neglected and landscaping is shifted into the background. Preference is given to activities associated with ownership as evidenced by the common tendency to award contracts for simple land consolidation. The numbers of awarded contracts for comprehensive and simple landscape consolidations from 1990 to the present were evaluated. Reasons for the observed stagnation of comprehensive land consolidation projects have been mentioned. Causes have been found and the problem was displayed from various positions. Finally, possible solutions have been found in order to stimulate discussion on the topic: why there is stagnation in designing of land consolidations in Slovakia.

  4. Foam consolidation and drainage.

    Jun, S; Pelot, D D; Yarin, A L

    2012-03-27

    A theoretical model of foam as a consolidating continuum is proposed. The general model is applied to foam in a gravity settler. It is predicted that liquid drainage from foam in a gravity settler begins with a slow drainage stage. Next, a stage with faster drainage occurs where the drainage rate doubles compared to the initial stage. The experiments conducted within the framework of this work confirmed the theoretical predictions and allowed measurements of foam characteristics. Foams of three different concentrations of Pantene Pro-V Classic Care Solutions shampoo were studied, as well as the addition of polyethylene oxide (PEO) in one case. The shampoo's main foaming components are sodium lauryl sulfate and sodium laureth sulfate. It is shown to what extent foam drainage is slowed down by using higher shampoo concentrations and how it is further decreased by adding polymer (PEO).

    Between 2010 and 2012 the Eastern Interconnection Planning Collaborative (EIPC) conducted a major long-term resource and transmission study of the Eastern Interconnection (EI). With guidance from a Stakeholder Steering Committee (SSC) that included representatives from the Eastern Interconnection States Planning Council (EISPC) among others, the project was conducted in two phases. Phase 1 involved a long-term capacity expansion analysis that involved creation of eight major futures plus 72 sensitivities. Three scenarios were selected for more extensive transmission- focused evaluation in Phase 2. Five power flow analyses, nine production cost model runs (including six sensitivities), and three capital cost estimations were developed during this second phase. The results from Phase 1 and 2 provided a wealth of data that could be examined further to address energy-related questions. A list of 14 topics was developed for further analysis. This paper brings together the earlier interim reports of the first 13 topics plus one additional topic into a single final report.

  7. Pipeline bottoming cycle study. Final report

    Energy Technology Data Exchange (ETDEWEB)

    1980-06-01

    The technical and economic feasibility of applying bottoming cycles to the prime movers that drive the compressors of natural gas pipelines was studied. These bottoming cycles convert some of the waste heat from the exhaust gas of the prime movers into shaft power and conserve gas. Three typical compressor station sites were selected, each on a different pipeline. Although the prime movers were different, they were similar enough in exhaust gas flow rate and temperature that a single bottoming cycle system could be designed, with some modifications, for all three sites. Preliminary design included selection of the bottoming cycle working fluid, optimization of the cycle, and design of the components, such as turbine, vapor generator and condensers. Installation drawings were made and hardware and installation costs were estimated. The results of the economic assessment of retrofitting bottoming cycle systems on the three selected sites indicated that profitability was strongly dependent upon the site-specific installation costs, how the energy was used and the yearly utilization of the apparatus. The study indicated that the bottoming cycles are a competitive investment alternative for certain applications for the pipeline industry. Bottoming cycles are technically feasible. It was concluded that proper design and operating practices would reduce the environmental and safety hazards to acceptable levels. The amount of gas that could be saved through the year 2000 by the adoption of bottoming cycles for two different supply projections was estimated as from 0.296 trillion ft/sup 3/ for a low supply projection to 0.734 trillion ft/sup 3/ for a high supply projection. The potential market for bottoming cycle equipment for the two supply projections varied from 170 to 500 units of varying size. Finally, a demonstration program plan was developed.

    Sleep plays an important role in the consolidation and integration of memory in a process called overnight memory consolidation. Previous studies indicate that ecstasy users have marked and persistent neurocognitive and sleep-related impairments. We extend past research by examining overnight memory consolidation among regular ecstasy users (n=12) and drug naïve healthy controls (n=26). Memory recall of word pairs was evaluated before and after a period of sleep, with and without interference prior to testing. In addition, we assessed neurocognitive performances across tasks of learning, memory and executive functioning. Ecstasy users demonstrated impaired overnight memory consolidation, a finding that was more pronounced following associative interference. Additionally, ecstasy users demonstrated impairments on tasks recruiting frontostriatal and hippocampal neural circuitry, in the domains of proactive interference memory, long-term memory, encoding, working memory and complex planning. We suggest that ecstasy-associated dysfunction in fronto-temporal circuitry may underlie overnight consolidation memory impairments in regular ecstasy users.

    The National Ignition Facility (NIF), a 1.8 MJ, 192 laser beam facility, will have anticipated fusion yields of up to 20 MJ from D-T pellets encased in a gold hohlraum target. The energy emitted from the target in the form of x rays, neutrons, target debris kinetic energy, and target shrapnel will be contained in a 5 m. radius spherical target chamber. various diagnostics will be stationed around the target at varying distances from the target. During each shot, the target will emit x rays that will vaporize nearby target facing surfaces including those of the diagnostics, the target positioner, and other chamber structures. This ablated vapor will be transported throughout the chamber, and will eventually condense and deposit on surfaces in the chamber, including the final optics debris shields. The research at the University of California at Berkeley relates primarily to the NIF chamber dynamics. The key design issues are the ablation of the chamber structures, transport of the vapor through the chamber and the condensation or deposition processes of those vaporized materials. An understanding of these processes is essential in developing a concept for protecting the fina optics debris shields from an excessive coating (> 10 A) of target debris and ablated material, thereby prolonging their lifetime between change-outs. At Berkeley, we have studied the physical issues of the ablation process and the effects of varying materials, the condensation process of the vaporized material, and design schemes that can lower the threat posed to the debris shields by these processes. The work or portions of the work completed this year have been published in several papers and a dissertation [l-5].

    Detailed structural mapping at several horizons in selected study areas within the Frio growth-fault trend demonstrates a pronounced variability in structural style. At Sarita in South Texas, shale mobilization produced one or more shale ridges, one of which localized a low-angle growth fault trapping a wedge of deltaic sediments. At Corpus Christi, shale mobilization produced a series of large growth faults, shale-cored domed anticlines, and shale-withdrawal basins, which become progressively younger basinward. At Blessing, major growth faults trapped sands of the Greta/Carancahua barrier system with little progradation. At Pleasant Bayou, a major early growth-fault pattern was overprinted by later salt tectonics - the intrusion of Danbury Dome and the development of a salt-withdrawal basin. At Port Arthur, low-displacement, long-lived faults formed on a sand-poor shelf margin contemporaneously with broad salt uplifts and basins. Variability in styles is related to the nature and extent of Frio sedimentation and shelf-margin progradation and to the presence or absence of salt. Structural styles that are conducive to the development of large geothermal reservoirs include blocks between widely spaced growth faults having dip reversal, salt-withdrawal basins, and shale-withdrawal basins. These styles are widespread on the Texas Gulf Coast. However, actually finding a large reservoir depends on demonstrating the existence of sufficient sandstone with adequate quality to support geopressured geothermal energy production.

    For the very soft clay with high water content, its void ratio, compressibility coefficient and permeability varied with stress during consolidation. It is necessary to use large strain consolidation based on the permeabilityvoid ratio relationship and effective stressvoid ratio relationship to analyze these properties. To overcome the disadvantages of conventional oedometer test, and determine the effective stressvoid relations of this kind of soil, osmotic pressure consolidation test for highly plastic clay study and the expression of permeabilityvoid ratio are performed. Therefore, the decided properties will be reasonably used for solving the large strain consolidation equation.

    Stress relaxation testing in compression at high temperature was performed on Cu-Cr-Zr alloys produced by consolidation of water atomized powders. Precipitation and recrystallization were monitored during stress relaxation experiments carried out at an ageing temperature of 723 K. Pre-straining imposed to the Cu-Cr-Zr samples prior to stress relaxation testing resulted in reduced hardness compared to that reported for conventionally-aged alloys; it also resulted in shorter times for achieving maximum strengthening on ageing.

    The variation of effective stress ratio of stratfied soil with semi-pervious boundaries and under cyclic loading was analyzed on the basis of Terzaghi's one-dimensional consolidation assumptions. A solution by Laplace Transform was obtained for the case when the soil was under time-varied loading. With numerical inversion of Laplace Transform, some useful results were obtained for several kinds of commonly encountered loadings. The results can be meaningful in engineering practice.

  19. Efforts to Consolidate Chalcogels with Adsorbed Iodine

    2013-08-28

    This document discusses ongoing work with non-oxide aerogels, called chalcogels, that are under development at the Pacific Northwest National Laboratory as sorbents for gaseous iodine. Work was conducted in fiscal year 2012 to demonstrate the feasibility of converting Sn2S3 chalcogel without iodine into a glass. This current document summarizes the work conducted in fiscal year 2013 to assess the consolidation potential of non-oxide aerogels with adsorbed iodine. The Sn2S3 and Sb13.5Sn5S20 chalcogels were selected for study. The first step in the process for these experiments was to load them with iodine (I2). The I2 uptake was ~68 mass% for Sn2S3 and ~50 mass% for Sb13.5Sn5S20 chalcogels. X-ray diffraction (XRD) of both sets of sorbents showed that metal-iodide complexes were formed during adsorption, i.e., SnI4 for Sn2S3 and SbI3 for Sb13.5Sn5S20. Additionally, metal-sulfide-iodide complexes were formed, i.e., SnSI for Sn2S3 and SbSI for Sb13.5Sn5S20. No XRD evidence for unreacted iodine was found in any of these samples. Once the chalcogels had reached maximum adsorption, the consolidation potential was assessed. Here, the sorbents were heated for consolidation in vacuum-sealed quartz vessels. The Sb13.5Sn5S20 chalcogel was heated both (1) in a glassy carbon crucible within a fused quartz tube and (2) in a single-containment fused quartz tube. The Sn2S3 chalcogel was only heated in a single-containment fused quartz tube. In both cases with the single-containment fused quartz experiments, the material consolidated nicely. However, in both cases, there were small fractions of metal iodides not incorporated into the final product as well as fused quartz particles within the melt due to the sample attacking the quartz wall during the heat treatment. The Sb13.5Sn5S20 did not appear to attack the glassy carbon crucible so, for future experiments, it would be ideal to apply a coating, such as pyrolytic graphite, to the inner walls of the fused quartz vessel to prevent

    Objective: To investigate the clinical features and the reason of misdiagnosis of consolidative primary pulmonary lymphoma. Methods: Retrospective study was conducted for three cases with consolidative primary pulmonary lymphoma(PPL). The relevant literatures of primary pulmonary lymphoma in recent years were also reviewed. Results: All patients had been misdiagnosed for a long time due to the non-specific clinical features. Conclusion: Consolidative PPL is difficult to diagnose and is misdiagnosed frequently in clinic. Definitive diagnosis of PPL requires an adequate biopsy specimen. The most important prognostic factor is the histology.

    1990-01-01

    Dynamic consolidation was investigated as a potential method for producing P/M metal matrix composites. In this study, 2124 aluminum powders were mixed with silicon carbide particulate and consolidated using explosives. Numerical simulations were performed to provide insight into the consolidation process and to aid in the selection of experimental conditions. The microstructure of the as-consolidated product was dependent upon processing variables. Careful control of the shock parameters allowed full density, crack free composites to be achieved in cylindrical geometries. Although full density was obtained, low fracture strengths suggested a lack of interparticle bonding, probably resulting from the limited ability to redistribute surface oxides during consolidation. 10 refs., 9 figs.

    For most soft soil,the consolidation process and the creep process were coupled and the character of settlement time curve was obtained by the consolidation test at the same time.A simple and continuous function was presented to express the whole process of consolidation including immediate settlement stage,the primary consolidation stage and the secondary consolidation stage.And the features of the continuous function were analyzed.The results of the long-term(duration to 18 months) consolidation test on clays from the Chek Lap Kok formation proved the rightness of the method.In the end,the parameter meanings of the continuous function were discussed.

  3. To Replay, Perchance to Consolidate.

    Directory of Open Access Journals (Sweden)

    Lisa Genzel

    2015-10-01

    Full Text Available After a memory is formed, it continues to be processed by the brain. These "off-line" processes consolidate the memory, leading to its enhancement and to changes in memory circuits. Potentially, these memory changes are driven by off-line replay of the pattern of neuronal activity present when the memory was being formed. A new study by Dhaksin Ramanathan and colleagues, published in PLOS Biology, demonstrates that replay occurs predominately after the acquisition of a new motor skill and that it is related to changes in memory performance and to the subsequent changes in memory circuits. Together, these observations reveal the importance of neuronal replay in the consolidation of novel motor skills.

    Memory encoding occurs rapidly, but the consolidation of memory in the neocortex has long been held to be a more gradual process. We now report, however, that systems consolidation can occur extremely quickly if an associative "schema" into which new information is incorporated has previously been created. In experiments using a hippocampal-dependent paired-associate task for rats, the memory of flavor-place associations became persistent over time as a putative neocortical schema gradually developed. New traces, trained for only one trial, then became assimilated and rapidly hippocampal-independent. Schemas also played a causal role in the creation of lasting associative memory representations during one-trial learning. The concept of neocortical schemas may unite psychological accounts of knowledge structures with neurobiological theories of systems memory consolidation.

  5. Consolidation and reconsolidation: two lives of memories?

    Science.gov (United States)

    McKenzie, Sam; Eichenbaum, Howard

    2011-07-28

    Most studies on memory consolidation consider the new information as if it were imposed on a tabula rasa, but considerable evidence indicates that new memories must be interleaved within a large network of relevant pre-existing knowledge. Early studies on reconsolidation highlighted that a newly consolidated memory could be erased after reactivation, but new evidence has shown that an effective reactivation experience must also involve memory reorganization to incorporate new learning. The combination of these observations on consolidation and reconsolidation highlights the fundamental similarities of both phenomena as the integration of new information and old, and it suggests reconsolidation = consolidation as a neverending process of schema modification.

    The focus of this study was to investigate the potential of hyperspectral imaging (HSI) in the monitoring of commercial consolidant products applied on wood samples. Poplar (Populus spp.) and walnut (Juglans Regia L.) were chosen for the consolidant application. Both traditional and innovative products were selected, based on acrylic, epoxy, and aliphatic compounds. Wood samples were stressed by freeze/thaw cycles in order to cause material degradation without the loss of wood components. Then the consolidant was applied under vacuum. The samples were finally artificially aged for 168 h in a solar box chamber. The samples were acquired in the short wave infrared (1000 to 2500 nm) range by SISUChema XL™ device (Specim, Finland) after 168 h of irradiation. As comparison, color measurement was also used as an economic, simple, and noninvasive technique to evaluate the deterioration and consolidation effects on wood. All data were then processed adopting a chemometric approach finalized to define correlation models, HSI based, between consolidating materials, wood species, and short-time aging effects.

    1999-04-01

    Identity consolidation during early adulthood was conceptualized as a process of investing oneself in new adult roles, responsibilities, and contexts and evaluating one's ongoing experience in order to construct a coherent, grounded, and positive identity. The current study longitudinally examined (age 21 to age 27) the roles of ego-resiliency, an important personality resource, and marriage, an important identity context, in the process of identity consolidation as it unfolded in a cohort of women who experienced early adulthood during the early 1960s. Prototypes of identity in marriage were developed to reflect the different ways these women invested and evaluated their identities in the context of marriage. Results showed that ego-resiliency at age 21 and the experience of identity in marriage at age 27 were both related to identity consolidation at age 27, and findings also suggested that the relation of age 21 ego-resiliency to age 27 identity consolidation was mediated by identity in marriage. Finally, successful identity consolidation was associated with increasing ego-resiliency from age 21 to age 27. Discussion focuses on the interaction between personality and social context in the process of identity consolidation and the role of identity consolidation in personality change.

    This report was prepared by Development Planning and Research Associates, Inc. under a contract with the Energy Research and Development Center of the University of Nebraska in cooperation with the Agricultural Products Industrial Utilization Committee and the State of Nebraska. Funding for this study was provided to the Energy Research and Development Center by the U.S. Department of Energy and the Old West Regional Commission. The primary objective of the study was to: determine the fiscal and market conditions under which the production of gasohol would be profitable for private producers. For purposes of this study, gasohol is a motor fuel consisting of 10 percent agriculturally-derived anhydrous ethanol and 90 percent unleaded gasoline. The study assumes that gasohol can be a fuel substitute for gasoline; indeed, the cost of gasoline will significantly influence that for gasohol. Gasoline prices are determined by factors external to ethanol; thus, the economic feasibility study of gasohol is in large part an economic feasibility study of fuel-grade ethanol production. More specifically, the study examined the following: the technical aspects of distributing, marketing, and using gasohol; the costs of the distribution and marketing of ethanol and gasohol; the energy balance of ethanol production; the cost of producing ethanol; the factors influencing ehtanol plant size and location; and the conditions that would make ethanol economicaly feasible for private producers.

  15. Entorhinal cortex and consolidated memory.

    Science.gov (United States)

    Takehara-Nishiuchi, Kaori

    2014-07-01

    The entorhinal cortex is thought to support rapid encoding of new associations by serving as an interface between the hippocampus and neocortical regions. Although the entorhinal-hippocampal interaction is undoubtedly essential for initial memory acquisition, the entorhinal cortex contributes to memory retrieval even after the hippocampus is no longer necessary. This suggests that during memory consolidation additional synaptic reinforcement may take place within the cortical network, which may change the connectivity of entorhinal cortex with cortical regions other than the hippocampus. Here, I outline behavioral and physiological findings which collectively suggest that memory consolidation involves the gradual strengthening of connection between the entorhinal cortex and the medial prefrontal/anterior cingulate cortex (mPFC/ACC), a region that may permanently store the learned association. This newly formed connection allows for close interaction between the entorhinal cortex and the mPFC/ACC, through which the mPFC/ACC gains access to neocortical regions that store the content of memory. Thus, the entorhinal cortex may serve as a gatekeeper of cortical memory network by selectively interacting either with the hippocampus or mPFC/ACC depending on the age of memory. This model provides a new framework for a modification of cortical memory network during systems consolidation, thereby adding a fresh dimension to future studies on its biological mechanism.

    2006-01-01

    Nanocrystalline WC-Co composite powder and coated tungsten diamond by using vacuum vapor deposition were consolidated by the spark plasma sintering (SPS) process to prepare diamond-enhanced WC-Co cemented carbide composite materials. The interface microstructures between coated tungsten diamond and WC-Co cemented carbide matrix were investigated by scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDXS). The results showed that there is a transitional layer between the diamond and the matrix, in which the carbon content is 62.97wt.%, and the content of cobalt in the transitional zone is 6.19wt.%; the content of cobalt in the WC-Co cemented carbide matrix is 6.07wt.%, in which the carbon content is 15.95wt.%, and the content of cobalt on the surface of diamond is 7.30wt.%, in which the carbon content is 80.38wt.%. The transitional zone prevents the carbon atom of the diamond from spreading to the matrix, in which the carbon content does coincide with the theoretical value of the raw nanocomposite powders, and the carbon content forms a graded distribution among the matrix, transitional zone, and the surface of diamond; after the 1280℃ SPS consolidated process the diamond still maintains a very good crystal shape, the coated tungsten on the surface of the diamond improves thermal stability of the diamond and increases the bonding strength of the interface between the diamond and the matrix.

    This report presents a number of case studies using the computer software package FORECAST MASTER (FM). The series studied and forecast are, aggregate monthly California Electricity Sales, system energy demand data from Ontario Hydro, peak demand data for the residential and commercial customers of Georgia Power Company, Massachusetts Electric commercial sales, Narragansett Electric commercial sales, average and peak demand using Georgia Power Company data. A variety of methods have been studied by each of the contributing authors; trend line fitting, exponential smoothing, Box-Jenkins univariate forecasting, vector autoregression, state space modeling, dynamic econometric models including time-varying parameters and general order serial correlation corrections. Thus both the data sets and the modeling/forecasting methodologies are varied. A number of conclusions emerge from these case studies: FM provides a powerful set of tools to aid a utility forecaster, a great deal of caution should be exercised in pre-processing the data; it can have unintended side effects, diagnostic tests are very useful in econometric models, the Akaike Information Criterion is a useful measure for selecting the best state space model, and state space and econometric approaches both need equal amounts of care in model analysis and presentation.

    Presented here are the results of inorganic geochemical studies on well cuttings from fourteen wells in the Big Sandy Gas Field. Both x-ray fluorescence and x-ray diffraction were used in analysis. Resultant mineralic data and elemental data were mapped by computer and by hand for five intervals of Ohio Shale and for the Berea/Bedford sequence. Comparisons of the geochemistry trend maps were made with lithology, structure, thermal maturation, gas open flow, and paleoenvironment. Techniques used included visual map comparison, computer map comparison programs utilizing correlation coefficients based on grid derived data sets, cluster analysis, x-y plots, and r/sup 2/ (coefficient of determination). A limited number of regional maps are included. It is concluded that inorganic geochemical analysis can be useful in: (1) suggesting paleoenvironmental trends; (2) establishing depositional trends; (3) enhancing exploration in terms of setting limits and pinpointing potential areas for hydrocarbon recovery; and (4) identification of likely locations for large gas fields when used with other geological studies. Elemental data analysis is the most accurate, and can be done quickly and inexpensively. It is concluded that the Big Sandy gas field area is a unique stratigraphic-structural gas trap, in which sedimentary factors, depositional basin features, plant evolution and occurrence, and structural elements all played important roles. Combinations of certain of these ingredients in different amounts may exist in other parts of the basin, and thus, suggest areas for hydrocarbon accumulation and potential recovery.

    The US market for domestic clothes washers is currently dominated by conventional, vertical axis washers, which typically require about 40 gallons of water for each load. Although small for an individual load, the fact that 35 billion loads of laundry are washed annually in the US results in a substantial quantity of water and energy use. Although much smaller, today`s market for high-efficiency clothes washers which use much less water and energy is growing albeit slowly as manufacturers are making washers based around tumble-action, horizontal axis designs available, information about their performance and benefits is being developed, and consumers are made aware of these benefits. To help build awareness of these benefits and to accelerate markets for high-efficiency washers, DOE, under its Energy Star Program and in cooperation with Maytag Appliances, conducted a field-evaluation of high-efficiency washers using Bern, Kansas (population approximately 200) as a test bed. Baseline washer performance data as well as customer washing behavior were obtained from data collected on the existing washers of more than 100 participants in this instrumented study. Following a 2-month initial study period, all conventional washers were replaced by high-efficiency, tumble action washers, and the experiment continued for another 3-month period. Based on measured data from over 20,000 loads of laundry, the impact of the washer replacement on (1) individual customers` energy and water consumption, (2) customers` laundry habits and perceptions, and (3) the community`s water supply and waste water systems were determined and reported.

    Full Text Available For any business is important to maintain a loyal customer base to help they to survive over time. This situation is accentuated even to the extent that increases competition and increases uncertainty. At present these are two features that are really developed. Because of the deep crisis in which we are, and other elements such as globalization and the development of new technologies and communication systems, we are faced with a scenario of intense competition and uncertainty manifest. It is therefore more necessary than ever to know in depth how to get customers to be faithful, and develop true loyalty strategies.In this paper, we present the sequential approach to the formation of consumer loyalty in order to deepen understanding of the concept. It is supplemented by studying the combined effect of switching costs as an element that promotes the continuity of the relationship. The results shows that the consumer takes a more cognitive process information in their initial assessments of the service and therefore in the early stages of loyalty. As advances in consumer behavior process becomes more direct and mechanic, so we can say that the customer-company bond is stronger.

    The study was designed to identify methods to determine adsorption applicable to Uranium Mill Tailings Remedial Action (UMTRA) Project sites, and to determine how changes in aquifer conditions affect metal adsorption, resulting retardation factors, and estimated contaminant migration rates. EPA and ASTM procedures were used to estimate sediment sorption of U, As, and Mo under varying groundwater geochemical conditions. Aquifer matrix materials from three distinct locations at the DOE UMTRA Project site in Rifle, CO, were used as the adsorbents under different pH conditions; these conditions stimulated geochemical environments under the tailings, near the tailings, and downgradient from the tailings. Grain size, total surface area, bulk and clay mineralogy, and petrography of the sediments were characterized. U and Mo yielded linear isotherms, while As had nonlinear ones. U and Mo were adsorbed strongly on sediments acidified to levels similar to tailings leachate. Changes in pH had much less effect on As adsorption. Mo was adsorbed very little at pH 7-7.3, U was weakly sorbed, and As was moderately sorbed. Velocities were estimated for metal transport at different pHs. Results show that the aquifer materials must be characterized to estimate metal transport velocities in aquifers and to develop groundwater restoration strategies for the UMTRA project.

  9. Study of brine treatment. Final report

    1977-11-01

    Available information pertinent to the treatment of geothermal brines was collected by literature search and then evaluated and summarized for use by the electric utility and geothermal industries. The information was screened from the geothermal, oil and gas, wastewater disposal, and boiler water treatment industries. The current state of knowledge and methodology concerning the treatment of geothermal brines to control scaling and corrosion in geothermal electric power production was assessed. Currently, geothermal scale in pipes and wells is removed by physical or chemical methods. There is a growing effort on developing methods to control scale formation for both fresh and spent brines, including pH adjustment and application of an electrical potential for fresh fluids, and coagulation to treat spent fluids. Current methods of corrosion control center around planned replacement of piping and other plant components, with efforts focused primarily on development of materials with improved corrosion resistance. Recommendations for additional work to improve brine treatment include the following: (1) chemical and physical characterization of brine and scale compositions, (2) basic data on the mechanism of scale formation and the effects of inhibitors, (3) development of instrumentation to monitor geothermal brine constituents, (4) correlation of laboratory results with field test data, and (5) screening of currently available commercial inhibitors for application to geothermal brines. An annotated bibliography of the reference material used in this study is included.

    The Pinellas Plant was built in 1956 to manufacture neutron generators, a principal component in nuclear weapons. In September 1990, the Department of Health and Rehabilitative Services (HRS) entered into an agreement with DOE to independently examine environmental monitoring data from the plant and health data from Pinellas County to determine if an epidemiological study is technically feasible to measure possible off-site health effects from ionizing radiation. Through normal plant operations, some radioactive materials have been released to the environment. Eighty percent of the total plant releases of 107,707 curies occurred in the early years of plant operation (1957--1960). The primary materials released were tritium gas, tritium oxide and krypton-85. Environmental monitoring for radioactive releases from the plant has been done regularly since 1975. The US Public Health Service Centers for Disease Control and Prevention (CDC), in assisting HRS, has determined that sufficient radiological data exist by which a dose reconstruction can be done. A dose reconstruction can provide an estimate of how much radiological exposure someone living in the vicinity of the Pinellas Plant may have suffered from environmental releases.

    A multi-well microbially enhanced oil recovery field pilot has been performed in the Southeast Vassar Vertz Sand Unit in Payne County, Oklahoma. The primary emphasis of the experiment was preferential plugging of high permeability zones for the purpose of improving waterflood sweep efficiency. Studies were performed to determine reservoir chemistry, ecology, and indigenous bacteria populations. Growth experiments were used to select a nutrient system compatible with the reservoir that encouraged growth of a group of indigenous nitrate-using bacteria and inhibit growth of sulfate-reducing bacteria. A specific field pilot area behind an active line drive waterflood was selected. Surface facilities were designed and installed. Injection protocols of bulk nutrient materials were prepared to facilitate uniform distribution of nutrients within the pilot area. By the end of December, 1991, 82.5 tons (75.0 tonnes) of nutrients had been injected in the field. A tracer test identified significant heterogeneity in the SEVVSU and made it necessary to monitor additional production wells in the field. The tracer tests and changes in production behavior indicate the additional production wells monitored during the field trial were also affected. Eighty two and one half barrels (13.1 m{sup 3}) of tertiary oil have been recovered. Microbial activity has increased CO{sub 2} content as indicated by increased alkalinity. A temporary rise in sulfide concentration was experienced. These indicate an active microbial community was generated in the field by the nutrient injection. Pilot area interwell pressure interference test results showed that significant permeability reduction occurred. The interwell permeabilities in the pilot area between the injector and the three pilot production wells were made more uniform which indicates a successful preferential plugging enhanced oil recovery project.

    Based on the layered visco-elastic soil model, according to the Terzaghi' s one dimensional consolidation theory, by the method of Laplace transform and matrix transfer technique, the problems about the consolidation of layered and saturated visco-elastic soils under arbitrary loading were solved. Through deductions, the general solution, in the terms of layer thickness, the modulus and the coefficients of permeability and Laplacian transform' s parameters was obtained. The strain and deformation of the layered and satu rated visco-elastic soils under arbitrary loading can be calculated by Laplace inversion. Ac cording to the results of several numerical examples, the consolidation of visco-elastic soils lags behind that of elastic soils. The development of effective stress and the displacement is vibrant process under cyclic loading. Finally, an engineering case is studied and the results prove that the methods are very effective.

    Full Text Available Hollowed villages consolidation(HVC is regarded as an imperative way to optimize the vacant and idle land arising in rural areas. Establishing an appropriate potential calculating model for HVC, which is suitable for the territorial functions of farming plain area, provides a basis for implementing HVC. Based on the current per capita construction land use standard method, this paper took the urgency, physical suitability and feasibility of HVC into consideration and established a calculating model of HVC potential. Finally, Yucheng City of Shandong Province was taken as a case to make an empirical analysis. The results showed that:(1 The urgency, physical suitability and feasibility of HVC presented a significant regional difference. The correction coefficients of the urgency, physical suitability and feasibility of HVC changed in the variation of 0.18~0.96, 0.69~0.84 and 0.11~0.77, respectively; (2 The theoretical and realistic potential of HVC in Yucheng City were 3 517.86 hm2 and 1 853.18 hm2, respectively. The new-added arable land coefficient was 16.89%. In recent years, the HVC in Yucheng City should focus on Shizhong residential district, Shiliwang Town and Fangsi Town. The other villages and towns might be set on in late stage. (3 In view of the lower physical suitability of HVC around Shizhong residential district, transforming the vacant and idle land into other construction land might be a better choice. Meanwhile, the land vacated in other towns should be transformed into arable land as much as possible via land consolidation.

  16. Consolidity: Mystery of inner property of systems uncovered

    2012-10-01

    Full Text Available This paper uncovers the mystery of consolidity, an inner property of systems that was amazingly hidden. Consolidity also reveals the secrecy of why strong stable and highly controllable systems are not invulnerable of falling and collapsing. Consolidity is measured by its Consolidity Index, defined as the ratio of overall changes of output parameters over combined changes of input and system parameters, all operating in fully fuzzy environment. Under this notion, systems are classified into consolidated, quasi-consolidated, neutrally consolidated, unconsolidated, quasi-unconsolidated and mixed types. The strategy for the implementation of consolidity is elaborated for both natural and man-made existing systems as well as the new developed ones. An important critique arises that the by-product consolidity of natural or built-as-usual system could lead to trapping such systems into a completely undesired unconsolidity. This suggests that the ample number of conventional techniques that do not take system consolidity into account should gradually be changed, and adjusted with improved consolidity-based techniques. Four Golden Rules are highlighted for handling system consolidity, and applied to several illustrative case studies. These case studies cover the consolidity analysis of the Drug Concentration problem, Predator-Prey Population problem, Spread of Infectious Disease problem, AIDS Epidemic problem and Arm Race model. It is demonstrated that consolidity changes are contrary (opposite in sign to changes of both stability and controllability. This is a very significant result showing that our present practice of stressing on building strong stable and highly controllable systems could have already jeopardized the consolidity behavior of an ample family of existing real life systems. It is strongly recommended that the four Golden Rules of consolidity should be enforced as future strict regulations of systems modeling, analysis, design and

  18. Memory consolidation in the cerebellar cortex.

    Directory of Open Access Journals (Sweden)

    Daniel O Kellett

    Full Text Available Several forms of learning, including classical conditioning of the eyeblink, depend upon the cerebellum. In examining mechanisms of eyeblink conditioning in rabbits, reversible inactivations of the control circuitry have begun to dissociate aspects of cerebellar cortical and nuclear function in memory consolidation. It was previously shown that post-training cerebellar cortical, but not nuclear, inactivations with the GABAA agonist muscimol prevented consolidation but these findings left open the question as to how final memory storage was partitioned across cortical and nuclear levels. Memory consolidation might be essentially cortical and directly disturbed by actions of the muscimol, or it might be nuclear, and sensitive to the raised excitability of the nuclear neurons following the loss of cortical inhibition. To resolve this question, we simultaneously inactivated cerebellar cortical lobule HVI and the anterior interpositus nucleus of rabbits during the post-training period, so protecting the nuclei from disinhibitory effects of cortical inactivation. Consolidation was impaired by these simultaneous inactivations. Because direct application of muscimol to the nuclei alone has no impact upon consolidation, we can conclude that post-training, consolidation processes and memory storage for eyeblink conditioning have critical cerebellar cortical components. The findings are consistent with a recent model that suggests the distribution of learning-related plasticity across cortical and nuclear levels is task-dependent. There can be transfer to nuclear or brainstem levels for control of high-frequency responses but learning with lower frequency response components, such as in eyeblink conditioning, remains mainly dependent upon cortical memory storage.

    This prospective randomized phase II study aimed to determine the safety and efficacy of deferasirox in preventing iatrogenic iron overload in patients receiving induction/consolidation chemotherapy for acute myeloid leukaemia (AML) ize. Serum ferritin, transferrin saturation and CRP were measured pre-, mid- and post- each chemotherapy cycle. Patients were randomized to receive either therapy with deferasirox vs. no deferasirox therapy once serum ferritin increased to >500 μg/l. The trial was stopped prematurely due to excess gastrointestinal (GI) and infectious toxicity demonstrable in the deferasirox arm, after 10 patients had been randomized to deferasirox and 6 patients to the control arm. Overall, deferasirox was poorly tolerated, with median maximum tolerated dose only 13·8 mg/kg/d and no patient able to tolerate doses >20 mg/kg/d. Median duration of deferasirox therapy was only 72 d (range 19-130 d), with 9/10 patients requiring unplanned dose interruptions and 4/10 patients unable to continue the drug predominantly due to GI effects. Although all 3 treatment-related deaths occurred in the deferasirox arm (P = 0·25), median overall survival was similar between treatment arms. Use of deferasirox to prevent iatrogenic iron overload in AML patients undertaking induction/consolidation is poorly tolerated and appears to be associated with excess GI and infectious toxicity.

    In-depth comprehending of the pore water pressure and the deformation in the procedure of mucky soil's consolidation has a significant meaning to study the theory of soil's drainage and consolidation. Though the text of the mucky soil in Huangshi Area ,by using the graded loading and once loading into same directional stress consolidation and unidirectional consolidation, to analysis the pore water pressure and the transformative rule during the whole process. The result indicates that two loading methods bring to different rules. Meanwhile the consolidation process will slow gradually when the pressure is lower to the threshold. The pressure will not as distinctive as the initial stage, even when the load is great. The mucky soil's consolidation in drainage has phases, it is caused by the change of the drainage speed about the free water and the leaked water. The main consolidation speed of the mucky soil is around 5minutes to 100minutes. If the consolidation pressure is close to the initial pressure, the consolidation coefficient is at the min. but the secondary consolidation coefficient is the max.%对深入了解土在外荷作用下的孔隙水压力与变形变化规律对研究土的排水固结机理具有重要意义.对黄石地区淤泥质土进行分级加荷与一次性加荷的各向等压固结试验及单向固结试验,分析全过程孔压与变形的变化规律,结果表明:两种加荷方式孔压消散的规律并不相同,当孔压降到相应某临界值以下时,固结过程会变得缓慢,即使在较大的外荷载作用下,土中孔压反映也远不如加载初期明显.固结排水过程具有阶段性,这主要是自由水与孔隙水排水速度变化所引起的.黄石淤泥质土的主固结时间总体在5~100 min范围内,当固结压力接近先期固结压力时固结系数最小,而次固结系数约为最大值.

    1995-12-01

    In order to meet their luminosity goals, linear colliders operating in the center-of-mass energy range from 3,50 to 1,500 GeV will need to deliver beams which are as small as a few Manometers tall, with x:y aspect ratios as large as 100. The Final Focus Test Beam (FFTB) is a prototype for the final focus demanded by these colliders: its purpose is to provide demagnification equivalent to those in the future linear collider, which corresponds to a focused spot size in the FFTB of 1.7 microns (horizontal) by 60 manometers (vertical). In order to achieve the desired spot sizes, the FFTB beam optics must be tuned to eliminate aberrations and other errors, and to ensure that the optics conform to the desired final conditions and the measured initial conditions of the beam. Using a combination of incoming-beam diagnostics. beam-based local diagnostics, and global tuning algorithms, the FFTB beam size has been reduced to a stable final size of 1.7 microns by 70 manometers. In addition, the chromatic properties of the FFTB have been studied using two techniques and found to be acceptable. Descriptions of the hardware and techniques used in these studies are presented, along with results and suggestions for future research.

    2005-01-01

    Terzaghi gave a theory of soil consolidation based on the effective stress principle, which was derived on several ideal assumptions to get a simplified theory. To avoid the limitations involved in Terzaghi's theory, many efforts are being made by scholars to solve the problems in practical engineering situations. This paper presents a generalized theory for one dimensional consolidation of saturated soft clay with variable compressibility and permeability. The semi-analytical solution presented here takes into account the well known empirical e-logk and e-logp'(σ') relations under instantaneous loading. Study of the consolidation behaviors showed that the ratio of Cc and Ck (the slope of e-logp and e-logk respectively) govern the ratio of consolidation. A simulative laboratory investigation with GDS advanced consolidation system was made to analyze the clay consolidation process and compare the results with the semi-analytical solution.

    In the first part of this review, we will present evidence showing a functional double dissociation between different structures of the medial temporal lobe in the consolidation of object and object-in-context recognition memory. In addition, we will provide evidence to support this differential participation through protein synthesis inhibitors and neurotransmitters antagonists and agonists. This evidence points out that the perirhinal, prefrontal and insular cortices consolidate the information of individual stimuli, i.e., objects, while the hippocampus consolidates the contextual information where the objects were experimented. In the second part of this review, we will present evidence that shows that the perirhinal cortex is also necessary for reconsolidation of ORM; the destabilization/re-stabilization memory process upon its activation. In the final part of this review, we will present evidence that shows that ORM reconsolidation is an independent process from its retrieval in the perirhinal cortex. Altogether, this review depicts part of the mechanisms by which the medial temporal lobe processes the functional components of recognition memory, in both consolidation and reconsolidation.

  4. Software Vulnerability Taxonomy Consolidation

    2004-12-07

    In today's environment, computers and networks are increasing exposed to a number of software vulnerabilities. Information about these vulnerabilities is collected and disseminated via various large publicly available databases such as BugTraq, OSVDB and ICAT. Each of these databases, individually, do not cover all aspects of a vulnerability and lack a standard format among them, making it difficult for end-users to easily compare various vulnerabilities. A central database of vulnerabilities has not been available until today for a number of reasons, such as the non-uniform methods by which current vulnerability database providers receive information, disagreement over which features of a particular vulnerability are important and how best to present them, and the non-utility of the information presented in many databases. The goal of this software vulnerability taxonomy consolidation project is to address the need for a universally accepted vulnerability taxonomy that classifies vulnerabilities in an unambiguous manner. A consolidated vulnerability database (CVDB) was implemented that coalesces and organizes vulnerability data from disparate data sources. Based on the work done in this paper, there is strong evidence that a consolidated taxonomy encompassing and organizing all relevant data can be achieved. However, three primary obstacles remain: lack of referencing a common ''primary key'', un-structured and free-form descriptions of necessary vulnerability data, and lack of data on all aspects of a vulnerability. This work has only considered data that can be unambiguously extracted from various data sources by straightforward parsers. It is felt that even with the use of more advanced, information mining tools, which can wade through the sea of unstructured vulnerability data, this current integration methodology would still provide repeatable, unambiguous, and exhaustive results.

    The extensional Berge fault (Devonian Kvamshesten Basin, West Norway) displays 430 m of syntectonic stratigraphy with fluvial sandstones and red fines exposed in a hanging wall growth section. The fault consists of three linked strands, where the offset diminishes and tips out stratigraphically upwards. Folds in the growth basin include a rollover and drag fold that record cumulative deformation during the main phases of fault slip, and a monocline that records the death and burial of the fault. Deformation styles in both the subbasin fill and the fault core indicate that the sediments were unconsolidated to poorly lithified during deformation. The upward-narrowing fault core consists of indurated breccias derived from footwall conglomerates, and mainly laminated fault gouge of subbasin affinity. Towards the hanging wall there is a mixed layer of sandstone lenses enclosed in fault gouge; this unit is variably sheared. In the damage zone deeper in the subbasin, truncating-style small-scale tabular shear bands show a general increase in frequency towards the fault, with abundant peaks in frequency next to the fault core. Smearing-style shear bands are merely encountered near the master fault. In the upper monocline realm, an overall broad zone of deformation reveals a moderate frequency of shear bands, characterized by clear distinctions between variably deformed layers. Some tabular dilation structures are found locally as layer-confined strain throughout the basin. We reason that the mixed layer is a product of fluid mobilization in/along the fault core. Fluid induced weakening combined with differential compaction would augment aseismic creep, as advocated for the creation of the smearing shear bands. We discuss a conceptual model in which damage zones grow by repeated rejuvenation and expand during propagation events, advocating that a distinctive damage zone becomes better expressed with increasing faulting events and depth (consolidation) in a growth basin.

    The chemical preservation and structural reintegration of natural stones applied in historical buildings is carried out by the use of different stone strengtheners. As these agents contain hydrogen, they offer good properties for neutron imaging. The main interest in the restoration process is the development of a suitable stone consolidant. In cooperation with the St. Stephans Cathedral and the geologists at Vienna University of Technology, we are investigating the penetration depth and distribution of different stone consolidants. These studies are being carried out with different stone samples, mostly porous natural building stones, limestones and sandstones. The two strengtheners used in this study are ethyl silicate ester (Wacker OH100) and dissolved polymethylmetacrylate (PMMA, Paraloid B72). Neutron radiography and neutron tomography can be used successfully to visualize the distribution of consolidants both in two and three dimensions.

    This exploratory research program was initiated to investigate the potential of using pulse power sources for powder consolidation, deposition and other high-energy high-rate processing. The characteristics of the high-energy-high-rate (1MJ/s) powder consolidation using megampere current pulses from a homopolar generator, were defined. Molybdenum Alloy TZM, a nickel-based metallic glass, copper/graphite composites, and P/M aluminum alloy X7091 were investigated. The powder-consolidation process produced high densification rates. Density values of 80% to 99% could be obtained with subsecond high-temperature exposure. Specific energy input and applied pressure were controlling process parameters. Time temperature transformation (TTT) concepts underpin a fundamental understanding of pulsed power processing. Inherent control of energy input, and time-to-peak processing temperature developed to be held to short times. Deposition experiments were conducted using an exploding-foil device (EFD) providing an armature feed to railgun mounted in a vacuum chamber. The material to be deposited - in plasma, gas, liquid, or solid state - was accelerated electromagnetically in the railgun and deposited on a substrate. Deposits of a wide variety of single- and multi-specie materials were produced on several types of substrates. In a series of ancillary experiments, pulsed-skin-effect heating and self quenching of metallic conductors was discovered to be a new means of surface modification by high-energy high-rate-processing.

    Full Text Available Hollow village renovation is an important content of rural land comprehensive consolidation. Under the core goal of sustainable utilization of land, revealing heavy metal pollution in typical soils of hollow village is the guiding link of the consolidation work, especially the reconstruction of farmland. Taking Yucheng City of Huang-Huai-Hai Plain as an example, this paper aims to analyze the content of As, Cd, Cr, Cu, Ni, Pb and Zn in seven kinds of typical soils, namely the village roads, sunning grounds, pit-pond sediments, woodland topsoils, courtyard farmlands, courtyard soils and clay wall soils which may be involved in the reconstruction of typical hollow village. Individual pollution index and comprehensive pollution index were used to evaluate the degree of heavy metal pollution according to the relevant national standards in order to provide the basis for safe and rational soil utilization during the hollow village consolidation. The results showed that in the above 7 types of tested soils, except for the pollution index of courtyard farmland was 0.85(pollution level Ⅱ, belong to "less clean" soil, other six types were <0.7(pollution level Ⅰ, belong to "clean" soil, which could be directly used in the hollow village consolidation for reconstruction of topsoil for agriculture. This study revealed the heavy metal pollution condition in the typical soils of plain agricultural areas. It has important reference value to the consolidation of hollow villages scientifically and the reconstruction of safe and high standard farmland.

    175 patients with acute myeloid leukemia were treated between February 1980 and March 1985 with a TAD-induction therapy, three intensified consolidation cycles (COAP, COAP, AD), and a two-year mild maintenance therapy. The median age of the patients was 44 years, range 15-68 years. 62.3% of all patients attained complete remission and 13.7% partial remission. The median duration of remission was 10 months and the median survival time of patients in complete remission was 20 months. Patients older than 50 years had a higher early death rate (17.6) than younger patients (8.9%), but no difference was found in remission rates or in the median duration of remission and of survival. These results are in line with those of comparable studies.

    The sediments of the modern Huanghe River subaqueous delta are easily to generate settlement and lead to topography change which is due to fast deposition rate, high void ratio, moisture content and compressibility. The sediment consolidation settlements and its contribution to the topography change in the northern modern Huanghe River subaqueous delta are studied based on drilling data, laboratory experiment results, and water depth measurements of different time. The results show that the final consolidation settlement of drill holes in the study area is between 1.17 and 3.21 m, and mean settlement of unit depth is between 2.30 and 5.30 cm/m based on the one-dimensional consolidation theory and Plaxis numerical model. The final consolidation settlement obtained by Plaxis numerical model is smaller than that obtained by the one-dimensional consolidation theory, and the difference is 3.4%–39.9%between the methods. The contribution of the consolidation settlement to the topographical change is at 20.2%–86.6%, and the study area can be divided into five different regions based on different contribution rates. In the erosion area, the actual erosion depth caused by hydrodynamics is lower than the changes of measured water depth, however, the actual deposition amount caused by hydrodynamics is much larger than the changes of water depth obtained by measured data in the equilibrium and deposition areas.

    Internal medicine residents at the Ochsner Clinic Foundation stay engaged with clinical work and have difficulty initiating and completing research and publishing their scholarly activities. Commonly cited barriers include lack of knowledge about institutional research programs, lack of confidence regarding medical writing skills, lack of time, and failure to understand the value of research. The residency directors at Ochsner initiated the Consolidated Academic and Research Exposition (CARE) program to teach basic research skills and encourage residents' interest and productivity in research. The CARE program includes 4 core components: house staff mentoring and the Resident Career Development Program, a journal club, medical writing instruction, and research engagement. Particular emphasis is given to projects that could be completed within a 1-month period and result in publication, enabling residents to use a 1-month elective rotation during their first postgraduate year. The sessions are mandatory for residents, except for those on specified rotations, including the critical care service and the night float rotation and those who are postcall. In 2010-2011, 6 residents submitted abstracts to the Louisiana Chapter of the American College of Physicians Associates meeting; 2 abstracts were accepted for presentation. In 2011-2012, there were 14 submissions, 4 of which were accepted for presentation. In 2010-2011, there were 4 submissions to the Southern Hospitalist Conference, which increased to 7 submissions in 2011-2012. The second best presentation award at the Southern Hospitalist Conference was also earned by a resident of this institution. The program saw a 110% total increase in scholarly activity from 2010-2011 to 2011-2012. The CARE program has been in existence for approximately 1 year. Preliminary results were tabulated based on research proposals, posters, abstracts, case reports, and presentations submitted and/or accepted at leading medical

    The average life duration of infrastructure being 30 years, preventive or corrective maintenance is not enough to guarantee the perpetuity of the operation of equipment and installation in order to assure the maintain of the patrimony in a functional state. At CERN, such is the age of the civil engineering infrastructure and the relative technical equipment that urgent and appropriate consolidation programs shall be established. The big number of aged buildings and equipment entails that priorities are defined. This paper realizes a portrait of the actual situation and related problems, based on data extracted from D7i and inventories carried out by TS/FM group; at the same time it defines an interventions planning which optimizes safety aspects and maintenance costs. The timing of these interventions depends on the availability of specific resources.

    The NTX experiment at the Heavy Ion Fusion Virtual National Laboratory is exploring the performance of neutralized final focus systems for high perveance heavy ion beams. The final focus scenario in an HIF driver consists of several large aperture quadrupole magnets followed by a drift section in which the beam space charge is neutralized by a plasma. This beam is required to hit a millimeter-sized target spot at the end of the drift section. The objective of the NTX experiments and associated theory and simulations is to study the various physical mechanisms that determine the final spot size (radius r{sub s}) at a given distance (f) from the end of the last quadrupole. In a fusion driver, f is the standoff distance required to keep the chamber wall and superconducting magnets properly protected. The NTX final quadrupole focusing system produces a converging beam at the entrance to the neutralized drift section where it focuses to a small spot. The final spot is determined by the conditions of the beam entering the quadrupole section, the beam dynamics in the magnetic lattice, and the plasma neutralization dynamics in the drift section. The main issues are the control of emittance growth due to high order fields from magnetic multipoles and image fields. In this paper, we will describe the theoretical and experimental aspects of the beam dynamics in the quadrupole lattice, and how these physical effects influence the final beam size. In particular, we present theoretical and experimental results on the dependence of final spot size on geometric aberrations and perveance.

    Extensive analysis of consolidation settlements induced by slurry shield tunnelling in construction of Hangzhou Qiantang River Tunnel was executed to explore their characteristics. A practical method to distinguish the consolidation settlements from immediate settlements was put forward. Formation mechanism, influencing factors, and control measures of consolidation settlements due to slurry shield tunnelling were summarized. This case study shows that: ①Both immediate and settlement long-term ground surface settlement in the transverse direction can be fitted using Peck equation with great precision. ②The transverse ground surface consolidation settlements usually do not conform to Gaussian curves. Maximum consolidation settlements develop at the ground surface above the tunnel centre or in the vicinity, from where they descend gradually with increasing distance. ③ Consolidation settlements contribute to widening the settlement trough width. ④The time corresponding to the turning point in settlement-time curve or settlement rate-time curve is proposed to be chosen as boundary to divide the immediate and consolidation settlements. ⑤Optimized control of slurry shield excavation parameters contributes to smaller disturbances to surrounding soils, consequently lowering consolidation settlements and their duration.%通过对杭州钱塘江隧道泥水盾构施工的分析,研究了泥水盾构施工引起的地面固结沉降的特点,提出划分地层损失沉降和固结沉降的实用方法,总结了盾构施工引起扰动土体固结沉降的机理、影响因素及控制措施.分析表明:无论是地层损失沉降还是长期沉降,均可用Peck公式较好地拟合;横向地面固结沉降曲线不符合高斯曲线形式,一般隧道轴线或附近地面固结沉降最大,向两侧递减;扰动土体固结使得横向沉降槽不断拓宽;软土地区盾构隧道施工,可取地面沉降曲线或沉降速度曲线的转折点作为地层损

    Memory consolidation benefits from post-training sleep. However, recent studies suggest that sleep does not uniformly benefit all memory, but instead prioritizes information that is important to the individual. Here, we examined the effect of test expectation on memory consolidation across sleep and wakefulness. Following reports that information with strong "future relevance" is preferentially consolidated during sleep, we hypothesized that test expectation would enhance memory consolidation across a period of sleep, but not across wakefulness. To the contrary, we found that expectation of a future test enhanced memory for both spatial and motor learning, but that this effect was equivalent across both wake and sleep retention intervals. These observations differ from those of least two prior studies, and fail to support the hypothesis that the "future relevance" of learned material moderates its consolidation selectively during sleep.

    2013-07-01

    Full Text Available Consolidation deformation occurs in clay liners under the self-weight of wastes at a simple garbage dump or dredged sediment dump, which leads to a decrease in the porosity. However, the migration of contaminants in clay liners is influenced by the porosity. Thus, the impact of consolidation deformation of clay liners on the migration of contaminants cannot be ignored. Based on Biot’s consolidation theory, the contaminant migration theory, and consideration of the three kinds of migration mechanisms of convection, diffusion, and adsorption, a one-dimensional migration model of contaminants in deforming porous media was established, and the finite difference method was adopted to obtain the numerical solutions for an established initial-boundary value problem. The impact of consolidation pressure on the migration law of a contaminant was studied. The results show that, regardless of adsorption modes, different consolidation pressures have similar impacts on the migration law of the contaminant. Namely, over a certain migration time, the greater the consolidation pressure is, the smaller the migration depth of the contaminant. The results also show that, while the migration time increases, the impact of a certain increment of consolidation pressure on the variation of contaminant concentration with the depth increases gradually and, while the migration depth increases, the impact of a certain increment of consolidation pressure on the variation of the contaminant concentration with time increases gradually.

    Two-step theories of memory formation suggest that an initial encoding stage, during which transient neural assemblies are formed in the hippocampus, is followed by a second step called consolidation, which involves re-processing of activity patterns and is associated with an increasing involvement of the neocortex. Several studies in human subjects as well as in animals suggest that memory consolidation occurs predominantly during sleep (standard consolidation model). Alternatively, it has been suggested that consolidation may occur during waking state as well and that the role of sleep is rather to restore encoding capabilities of synaptic connections (synaptic downscaling theory). Here, we review the experimental evidence favoring and challenging these two views and suggest an integrative model of memory consolidation.

    Full Text Available                         AbstractFiscal consolidation is the implementation of policies to reduce government expenditures and the public debt ratio to GDP. These policies are used to ensure fiscal discipline and minimize the debt stock by either tax or expenditure side. In this respect, the importance of fiscal consolidation policy is to ensure fiscal discipline without making negative effects on economic growth and economic life. Besides the conceptual framework, periods and the success criteria of fiscal consolidation are important factors for evaluating the success or failure of fiscal consolidation. In this study, it has been identified that there is no consensus on these criteria in the literature.Keywords: Fiscal Consolidation, Budget Deficits,Government Spending, Public EconomyJEL Classification Codes: E62, H32, H62

However, the efficacy of consolidation chemotherapy (CCT in LD-SCLC remains controversial despite several studies that were performed in the early years of CCT use. The aim of this study was to reevaluate the effectiveness and toxicities associated with CCT. Methods: This retrospective analysis evaluated 177 patients with stage IIIA and IIIB small-cell lung cancer (SCLC who underwent CCRT from January 2001 to December 2013 at Sun Yat-Sen University Cancer Center (SYSUCC. Overall survival (OS and progression-free survival (PFS were analyzed using Kaplan–Meier methods. Univariate and multivariate analyses were performed to analyze patient prognosis factors. Results: Among the 177 patients, 72 (41% received CCT and 105 (59% did not receive CCT. PFS was significantly better for patients in the CCT group compared to that for patients in the non-CCT group (median PFS: 17.0 vs 12.9 months, respectively, P=0.031, whereas the differences in OS were not statistically significant (median OS: 31.6 vs 24.8 months, respectively, P=0.118. The 3- and 5-year OS rates were 33.3% and 20.8% for patients in the CCT group and 27.6% and 6.7% for patients in the non-CCT group, respectively. Multivariate analysis revealed that having a pretreatment carcinoembryonic antigen level <5 ng/mL (P=0.035, having undergone prophylactic cranial irradiation (P<0.001, and having received CCT (P=0.002 could serve as favorable independent prognostic factors

    2008-07-01

    Tests of object recognition memory, or the judgment of the prior occurrence of an object, have made substantial contributions to our understanding of the nature and neurobiological underpinnings of mammalian memory. Only in recent years, however, have researchers begun to elucidate the specific brain areas and neural processes involved in object recognition memory. The present review considers some of this recent research, with an emphasis on studies addressing the neural bases of perirhinal cortex-dependent object recognition memory processes. We first briefly discuss operational definitions of object recognition and the common behavioural tests used to measure it in non-human primates and rodents. We then consider research from the non-human primate and rat literature examining the anatomical basis of object recognition memory in the delayed nonmatching-to-sample (DNMS) and spontaneous object recognition (SOR) tasks, respectively. The results of these studies overwhelmingly favor the view that perirhinal cortex (PRh) is a critical region for object recognition memory. We then discuss the involvement of PRh in the different stages--encoding, consolidation, and retrieval--of object recognition memory. Specifically, recent work in rats has indicated that neural activity in PRh contributes to object memory encoding, consolidation, and retrieval processes. Finally, we consider the pharmacological, cellular, and molecular factors that might play a part in PRh-mediated object recognition memory. Recent studies in rodents have begun to indicate the remarkable complexity of the neural substrates underlying this seemingly simple aspect of declarative memory.

    Sleep is an active state that plays an important role in the consolidation of memory. It has been found to enhance explicit memories in both adults and children. However, in contrast to adults, children do not always show a sleep-related improvement in implicit learning. The majority of research on sleep-dependent memory consolidation focuses on adults; hence, the current study examined sleep-related effects on two tasks in children. Thirty-three typically developing children aged 6-12 years took part in the study. Actigraphy was used to monitor sleep. Sleep-dependent memory consolidation was assessed using a novel non-word learning task and the Tower of Hanoi cognitive puzzle, which involves discovering an underlying rule to aid completion. Children were trained on the two tasks and retested following approximately equal retention intervals of both wake and sleep. After sleep, children showed significant improvements in performance of 14% on the non-word learning task and 25% on the Tower of Hanoi task, but no significant change in score following the wake retention interval. Improved performance on the Tower of Hanoi may have been due to children consolidating explicit aspects of the task, for example rule-learning or memory of previous sequences; thus, we propose that sleep is necessary for consolidation of explicit memory in children. Sleep quality and duration were not related to children's task performance. If such experimental sleep-related learning enhancement is generalizable to everyday life, then it is clear that sleep plays a vital role in children's educational attainment.

Black-Right-Pointing-Pointer The consolidated disks comprised ultrafine grains with high density of dislocations. Black-Right-Pointing-Pointer Quasicrystalline dispersoids strengthen the material by increasing the dislocation density. Black-Right-Pointing-Pointer Twinning in the Mg matrix was marginal during HPT. - Abstract: Mg{sub 95}Zn{sub 4.3}Y{sub 0.7} (at.%) alloy powder produced by an inert gas-atomizer was consolidated by high-pressure torsion (HPT) at room temperature and 373 K. The phase composition and the microstructure were investigated by X-ray diffraction and the microstructural parameters were correlated to the yield strength. HPT-processing yielded an ultrafine-grained microstructure with high dislocation density, leading to a large yield strength of the samples. Both the gas-atomized powder and the consolidated samples contained an icosahedral Mg{sub 3}YZn{sub 6} phase (I-phase) besides the main phase of {alpha}-Mg. It turned out that the I-phase dispersoids strengthen the consolidated material indirectly by increasing the dislocation density due to their pinning effect.

    final product of HPA axis activity. These hormones act on specialized receptors located within all body cells; upon activation by ligand binding, these receptors interact with specific regions of DNA, thereby regulating gene expression (Tsigos & Chrousos, 2002. The lipidic nature of glucocorticoids allows them to cross the blood-brain barrier and enter the brain, which may influence cognitive function. The aim of this study was to determine the effects of stress (movement restriction or the stress hormone corticosterone (intraperitoneal injection of corticosterone, on spatial memory consolidation in adult male Wistar rats in two different post-training time windows (immediately or 3 hours after training involved in memory consolidation. Rats were trained in a spatial memory task in the Barnes maze and a memory retention test was performed twenty-four hours after training. The results showed that both stress and corticosterone were able to enhance memory consolidation when they were administered immediately after training. However, when the same treatments were administered three hours after training, there was not a significant change in the performance during the test carried out after twenty-four hours. These results suggest, on the one hand, that memory consolidation process can be improved using treatments that modulate cellular gene expression programs, as stress and corticosterone, when they are applied during the first window of memory consolidation. Additionally, although the second period of memory consolidation is also related to a particular gene expression and protein synthesis program, the treatments used in the present study were not able to modulate memory consolidation when administered during this period. As the molecular events involved in the second window of memory consolidation may be different from those involved in the first one, it is possible that the molecular changes generated by stress and corticosterone do not interact with them in a way

  20. Multnomah County Hydrokinetic Feasibility Study: Final Feasibility Study Report

    2012-03-15

    HDR has completed a study of the technical, regulatory, and economic feasibility of installing hydrokinetic turbines under the Morrison, Broadway, and Sellwood bridges. The primary objective of installing hydrokinetic turbines is a demonstration of in-stream hydrokinetic technologies for public education and outreach. Due to the low gradient of the Lower Willamette and the effects of the tide, velocities in the area in consideration are simply not high enough to economically support a commercial installation. While the velocities in the river may at times provide enough energy for a commercial turbine to reach capacity, the frequency and duration of high flow events which provide suitable velocities is not sufficient to support a commercial hydrokinetic installation. We have observed that over an 11 year period, daily average velocities in the Lower Willamette exceeded a nominal cut-in speed of 0.75 m/s only 20% of the time, leaving net zero power production for the remaining 80% of days. The Sellwood Bridge site was estimated to have the best hydrokinetic resource, with an estimated average annual production of about 9,000 kWh. The estimated production could range from 2,500 kWh to 15,000 kWh. Based on these energy estimates, the amount of revenue generated through either a power purchase agreement (PPA) or recovered through net metering is not sufficient to repay the project costs within the life of the turbine. The hydrokinetic resource at the Morrison and Broadway Bridges is slightly smaller than at the Sellwood Bridge. While the Broadway and Morrison Bridges have existing infrastructure that could be utilized, the project is not expected to generate enough revenue to repay the investment. Despite low velocities and energy production, the sites themselves are favorable for installation of a demonstration or experimental project. With high public interest in renewable energy, the possibility exists to develop a hydrokinetic test site which could provide

    Memory consolidation is most commonly described by the standard model, which proposes an initial binding role for the hippocampus which diminishes over time as intracortical connections are strengthened. Recent evidence suggests that slow wave sleep (SWS) plays an essential role in this process. Existing animal and human studies have suggested that memories which fit tightly into an existing knowledge framework or schema might use an alternative consolidation route in which the medial prefrontal cortex takes on the binding role. In this study we sought to investigate the role of sleep in this process using a novel melodic memory task. Participants were asked to remember 32 melodies, half of which conformed to a tonal schema present in all enculturated listeners, and half of which did not fit with this schema. After a 24-h consolidation interval, participants were asked to remember a further 32 melodies, before being given a recognition test in which melodies from both sessions were presented alongside some previously unheard foils. Participants remembered schema-conformant melodies better than non-conformant ones. This was much more strongly the case for consolidated melodies, suggesting that consolidation over a 24-h period preferentially consolidated schema-conformant items. Overnight sleep was monitored between the sessions, and the extent of the consolidation benefit for schema-conformant items was associated with both the amount of REM sleep obtained and EEG theta power in frontal and central regions during REM sleep. Overall our data suggest that REM sleep plays a crucial role in the rapid consolidation of schema-conformant items. This finding is consistent with previous results from animal studies and the SLIMM model of Van Kesteren, Ruiter, Fernández, and Henson (2012), and suggest that REM sleep, rather than SWS, may be involved in an alternative pathway of consolidation for schema-conformant memories.

    Exposure to negative environmental events triggers defensive behavior and leads to the formation of aversive associative memory. Cellular and molecular changes in the central nervous system underlie this memory formation, as well as the associated behavioral changes. In general, memory process is established in distinct phases such as acquisition, consolidation, evocation, persistence, and extinction of the acquired information. After exposure to a particular event, early changes in involved neural circuits support the memory consolidation, which corresponds to the short-term memory. Re-exposure to previously memorized events evokes the original memory, a process that is considered essential for the reactivation and consequent persistence of memory, ensuring that long-term memory is established. Different environmental stimuli may modulate the memory formation process, as well as their distinct phases. Among the different environmental stimuli able of modulating memory formation is the physical exercise which is a potent modulator of neuronal activity. There are many studies showing that physical exercise modulates learning and memory processes, mainly in the consolidation phase of the explicit memory. However, there are few reports in the literature regarding the role of physical exercise in implicit aversive associative memory, especially at the persistence phase. Thus, the present study aimed to investigate the relationship between swimming exercise and the consolidation and persistence of contextual and auditory-cued fear memory. Male Wistar rats were submitted to sessions of swimming exercise five times a week, over six weeks. After that, the rats were submitted to classical aversive conditioning training by a pairing tone/foot shock paradigm. Finally, rats were evaluated for consolidation and persistence of fear memory to both auditory and contextual cues. Our results demonstrate that classical aversive conditioning with tone/foot shock pairing induced

    The purpose of this study was to analyse archery performance among eight archers of different abilities by means of displacement pull-hand measurements during the final push-pull phase of the shoot. The archers showed an irregular displacement negatively related to their technical level. Displacement signal analysis showed high power levels in both the 0-5 Hz and 8-12 Hz ranges. The latter peak corresponds to electromyographic tremor observed during a prolonged push-pull effort. The results are discussed in relation to some potentially helpful training procedures such as biofeedback and strength conditioning.

  6. Prospect for Developing a Consolidated Bioprocessing (CBP) Strain Using Xylan as the Substrate: the Case Study of Yarrowia lipolytica

    2016-07-08

    To achieve the goal of developing a direct microbial sugar conversion platform for the production of lipids and drop-in fuels from cellulosic biomass substrate, Yarrowia lipolytica was used to investigate its potential for being developed as CBP strain by expressing cellulase and xylanase enzymes. Y. lipolytica is known to accumulate lipids intracellularly and is capable of metabolizing glucose and xylose to produce lipids; however, due to the lack of the biomass degrading enzymes, it cannot directly utilize lignocellulosic substrates as carbon sources. While research is continuing on the development of a Y. lipolytica strain able to degrade cellulose, in this study, we present successful expression of several xylanases in Y. lipolytica. To the best of our knowledge, this is the first study introducing heterologous hemicellulose genes into the genome of Y. lipolytica. SDS-PAGE and western blotting analysis showed that the endo-xylanase gene XynII and exo-xylosidase gene XlnD were successfully expressed and secreted, and the expressed xylanases were likely either not or sparsely glycosylated, which is advantageous for expression of heterologous proteins from any species. Enzymatic activity tests further demonstrated active expression of XynII and XlnD in Y. lipolytica. Furthermore, synergistic action on converting xylan to xylose was observed when XlnD worked in concert with XynII. XlnD was able to work on the xylo-oligomers generated by XynII, enhancing the xylan conversion to monomeric xylose. The successful expression of these xylanases in Yarrowia further advances us towards our goal to develop a direct microbial conversion process using this organism. and xylose to produce lipids; however, due to the lack of the biomass degrading enzymes, it cannot directly utilize lignocellulosic substrates as carbon sources. While research is continuing on the development of a Y. lipolytica strain able to degrade cellulose, in this study, we present successful expression of

    Full Text Available Concrete instability may lead to the non-uniform distribution of its properties. The homogeneity of self-consolidating concrete in vertically cast members was therefore explored in this study, analyzing both resistance to segregation and pore structure uniformity. To this end, two series of concretes were prepared, self-consolidating and traditional vibrated materials, with different w/c ratios and types of cement. The results showed that selfconsolidating concretes exhibit high resistance to segregation, albeit slightly lower than found in the traditional mixtures. The pore structure in the former, however, tended to be slightly more uniform, probably as a result of less intense bleeding. Such concretes are also characterized by greater bulk density, lower porosity and smaller mean pore size, which translates into a higher resistance to pressurized water. For pore diameters of over about 0.5 μm, however, the pore size distribution was found to be similar to the distribution in traditional concretes, with similar absorption rates.En este trabajo se estudia la homogeneidad de los hormigones autocompactantes en piezas hormigonadas verticalmente, determinando su resistencia a la segregación y la uniformidad de su estructura porosa, dado que la pérdida de estabilidad de una mezcla puede conducir a una distribución no uniforme de sus propiedades. Para ello se han fabricado dos tipos de hormigones, uno autocompactante y otro tradicional vibrado, con diferentes relaciones a/c y distintos tipos de cemento. Los resultados ponen de manifiesto que los hormigones autocompactantes presentan una buena resistencia a la segregación, aunque algo menor que la registrada en los hormigones tradicionales. A pesar de ello, su estructura porosa tiende a ser ligeramente más uniforme, debido probablemente a un menor sangrado. Asimismo, presentan una mayor densidad aparente, una menor porosidad y un menor tamaño medio de poro, lo que les confiere mejores

    This is a final report for the Phase II study entitled ``Ripeness Sensor Development.`` The overall objective of the study was the development of a prototype device capable of testing whole fruits for sugar content. Although ripeness and sugar content are not synonymous, they are closely related. Furthermore, the consumer`s acceptance of or preference for fruits is strongly influenced by sugar content. Therefore, the device was called a ripeness sensor. The principle behind the measurement is proton magnetic resonance ({sup 1}H-MR). For several decades, chemists, pharmacists and other scientists have been using {sup 1}H-MR to investigate chemical structure and composition. More recently, the technique has been used in laboratories of the food industry for quality control. This effort represents one of the first attempts to adapt {sup 1}H-MR to use in a commercial facility. 28 refs., 36 figs., 7 tabs.

There appears to be a dose-response relationship in favour of higher intensity exercise in order to augment off-line effects and strengthen procedural memory.......A single bout of high intensity aerobic exercise (~90% VO2peak) was previously demonstrated to amplify off-line gains in skill level during the consolidation phase of procedural memory. High intensity exercise is not always a viable option for many patient groups or in a rehabilitation setting...... where low to moderate intensities may be more suitable. The aim of this study was to investigate the role of intensity in mediating the effects of acute cardiovascular exercise on motor skill learning.

    1977-12-01

    In the interval from February of 1972 through December of 1977, studies were conducted relating to the anatomical feasibility of implanting a total artificial heart system. These studies included both the calf as an experimental animal as well as the ultimate human recipient of the artificial heart system. Studies with the calf included definition of the thoracic anatomy relative to the size, shape, and vascular connections for implanting the blood pump. To test the animal's tolerance to an implanted engine system, mockups of the thermal converter were implanted chronically in various locations within the calf. No problems developed in retroperitoneal or intraperitoneal implants ranging from 8 to 15 months. A study to determine accelerations experienced by an abdominally implanted thermal converter was performed in calves. Under the most severe conditions, accelerations of a maximum of 34 Gs were experienced. The largest effort was devoted to defining the human anatomy relative to implanting an artificial heart in the thorax. From a number of data sources, including cadavers as well as living patients, a quantitative, statistical analysis of the size and shape of the male thorax was obtained. Finally, an in vivo study of a functional intrathoracic compliance bag in a calf demonstrated the feasibility of this method.

    Full Text Available The purpose of this article is to analyze the current state of consolidated reporting practice harmonization concerning the choice of presenting the income statement, the changes in equity, the methods used for presenting the cash flow statement, the extant methods for evaluating and reporting goodwill, the extant methods in which jointly controlled entities are accounted in the consolidated financial statements, or the choice for recognizing investments in subsidiaries, jointly controlled entities and associates in the separate statements of the parent company. In order to achieve our goal we selected the first 10 groups, in order of their capitalization value, that were listed on each of the following capital markets: London Stock Exchange, NYSE Euronext (Paris Stock Exchange and Deutsche Börse (Frankfurt Stock Exchange and we analyzed, in a qualitative and in a quantitative manner, for a period of six years starting with 2007, their consolidated financial statements with the design to establish exactly which of the aspects stated in the International Financial Reporting Standards were being used for the items presented above. In order to complete the empirical research part of the paper that addresses from a comparative perspective the evaluation of the degree of material harmony between the reporting practices of groups listed on the three stock exchanges above-mentioned, we used statistical and mathematical methods represented by the I Index first described by Van der Tas. Taking into account the fact that since 2005 all listed companies on the European stock exchanges were required to adopt the international accounting standards for their consolidated financial disclosures, the degree of material harmony was studied only in reference to those requirements that presented two methods or possibilities of disclosure.Our findings suggest that the groups analyzed present a high degree of material harmonization with respect to the reporting

    It has been underlined that the local communities’ consolidation process in the contemporary world is the problem which has both empirical and theoretical importance. Depending on the size of the local area, local polices are taking different forms. As usual, they provide an agreement and compromise solutions based on issues that are important to the local community. The experience of the developed democracies has shown that local assemblies ensure the establishment of coalitions based on short-termed procedures. The study has tested that an important aspect of the formation of local communities consolidated position is based on development issues and civil participation. It is especially visible in the United States and the EU countries. The municipality level determines the quality of local political bodies, which is formed on party basis. For contemporary Ukraine important tools for provision of political responsibility are forces, which take care about the local communities and determine their development for a long period. Overall, the consolidation of political forces in the local government system is an important task that determines the need for the adoption of regulatory instruments which would ensure the harmonious and constructive political cooperation regardless of their ideological positions.

    2011-08-01

    The present study investigated working memory consolidation in focused and distributed attention tasks by examining the time course of the consolidation process (Experiment 1) and its dependence on capacity-limited central resources (Experiment 2) in both tasks. In a match-to-sample design using masks at various intervals to vary consolidation rates, the participants performed either an identification task (focused attention) or a mean estimation task (distributed attention) with (Experiment 1) or without (Experiment 2) prior knowledge of what task they were to perform. We found that consolidation in the distributed attention task was more efficient and was about twice as fast as in the focused attention task. In addition, both tasks suffered interference when they had to be performed together, indicating that both types of attention rely on a common set of control processes. These findings can be attributed to differences in the resolution of object representations and in the scope of attention associated with focused and distributed attention.

  4. Manufacturing Titanium Metal Matrix Composites by Consolidating Matrix Coated Fibres

    2005-01-01

    Titanium metal matrix composites (TiMMCs) reinforced by continuous silicon carbide fibres are being developed for aerospace applications. TiMMCs manufactured by the consolidation of matrix-coated fibre (MCF) method offer optimum properties because of the resulting uniform fibre distribution, minimum fibre damage and fibre volume fraction control. In this paper, the consolidation of Ti-6Al-4V matrix-coated SiC fibres during vacuum hot pressing has been investigated. Experiments were carried out on multi-ply MCFs under vacuum hot pressing (VHP). In contrast to most of existing studies, the fibre arrangement has been carefully controlled either in square or hexagonal arraysthroughout the consolidated sample. This has enabled the dynamic consolidation behaviour of MCFs to be demonstrated by eliminating the fibre re-arrangement during the VHP process. The microstructural evolution of the matrix coating was reported and the deformation mechanisms involved were discussed.

    Wang, Szu-Han; Morris, Richard G M

    2010-01-01

    This review, focusing on work using animals, updates a theoretical approach whose aim is to translate neuropsychological ideas about the psychological and anatomical organization of memory into the neurobiological domain. It is suggested that episodic-like memory consists of both automatic and controlled components, with the medial temporal mediation of memory encoding including neurobiological mechanisms that are primarily automatic or incidental. These ideas, in the cognitive and behavioral domain, are linked to neurophysiological ideas about cellular consolidation concerning synaptic potentiation, particularly the relationship between protein synthesis-dependent long-term changes and shorter-lasting post-translational mechanisms. Ideas from psychology about mental schemas are considered in relation to the phenomenon of systems consolidation and, specifically, about how prior knowledge can alter the rate at which consolidation occurs. Finally, the hippocampal-neocortical interactions theory is updated in relation to reconsolidation, a process that enables updating of stored memory traces in response to novelty.

    Full Text Available This paper reviews research articles published in the former USSR and post-soviet countries on the consolidation of powder materials using electric current that passes through the powder sample and/or a conductive die-punch set-up. Having been published in Russian, many of the reviewed papers are not included in the mainstream electronic databases of the scientific articles and thus are not known to the scientific community. The present review is aimed at filling this information gap. In the paper, the electric current-assisted sintering techniques based on high- and low-voltage approaches are presented. The main results of the theoretical modeling of the processes of electromagnetic field-assisted consolidation of powder materials are discussed. Sintering experiments and related equipment are described and the major experimental results are analyzed.

    This paper reviews research articles published in the former USSR and post-soviet countries on the consolidation of powder materials using electric current that passes through the powder sample and/or a conductive die-punch set-up. Having been published in Russian, many of the reviewed papers are not included in the mainstream electronic databases of the scientific articles and thus are not known to the scientific community. The present review is aimed at filling this information gap. In the paper, the electric current-assisted sintering techniques based on high- and low-voltage approaches are presented. The main results of the theoretical modeling of the processes of electromagnetic field-assisted consolidation of powder materials are discussed. Sintering experiments and related equipment are described and the major experimental results are analyzed. Sintering conditions required to achieve the desired properties of the sintered materials are provided for selected material systems. Tooling materials used in the electric current-assisted consolidation set-ups are also described. PMID:28788337

  10. Synaptic consolidation across multiple timescales

    Full Text Available The brain is bombarded with a continuous stream of sensory events, but retains only a small subset in memory. The selectivity of memory formation prevents our memory from being overloaded with irrelevant items that would rapidly bring the brain to its storage limit; moreover, selectivity also prevents overwriting previously formed memories with new ones. Memory formation in the hippocampus, as well as in other brain regions, is thought to be linked to changes in the synaptic connections between neurons. In this view, sensory events imprint traces at the level of synapses that reflect potential memory items. The question of memory selectivity can therefore be reformulated as follows: what are the reasons and conditions that some synaptic traces fade away whereas others are consolidated and persist? Experimentally, changes in synaptic strength induced by 'Hebbian' protocols fade away over a few hours (early long-term potentiation or e-LTP, unless these changes are consolidated. The experiments and conceptual theory of synaptic tagging and capture (STC provide a mechanistic explanation for the processes involved in consolidation. This theory suggests that the initial trace of synaptic plasticity sets a tag at the synapse, which then serves as a marker for potential consolidation of the changes in synaptic efficacy. The actual consolidation processes, transforming e-LTP into late LTP (l-LTP, require the capture of plasticity-related proteins (PRP. We translate the above conceptual model into a compact computational model that accounts for a wealth of in vitro data including experiments on cross-tagging, tag-resetting and depotentiation. A central ingredient is that synaptic traces are described with several variables that evolve on different time scales. Consolidation requires the transmission of information from a 'fast' synaptic trace to a 'slow' one through a 'write' process, including the formation of tags and the production of PRP for the

Based on data from 2001 to 2007,with valuation model,this paper tests whether consolidated financial statements provide more additional value information than that provided in parent individual financial statements,and whether consolidated financial statements based on Entity Theory provide more additional value information than that based on Parent Theory. The results show that,although not all year-samples support the hypothesis that consolidated financial statements dominate parent individual statements,due to the fact that cosolidated financial statements can disclose deeply the risks related to leverage and profitability,cosolidated financial statements are useful. The results also show that,consolidated financial statements based on Entity Theory dominate that based on Parent Theory.

    It has been suggested that healthy sleep facilitates the consolidation of newly acquired memories and underlying brain plasticity. The authors tested the hypothesis that patients with primary insomnia (PI) would show deficits in sleep-related memory consolidation compared to good sleeper controls (GSC). The study used a four-group parallel design (n=86) to investigate the effects of 12 h of night-time, including polysomnographically monitored sleep ('sleep condition' in PI and GSC), versus 12 h of daytime wakefulness ('wake condition' in PI and GSC) on procedural (mirror tracing task) and declarative memory consolidation (visual and verbal learning task). Demographic characteristics and memory encoding did not differ between the groups at baseline. Polysomnography revealed a significantly disturbed sleep profile in PI compared to GSC in the sleep condition. Night-time periods including sleep in GSC were associated with (i) a significantly enhanced procedural and declarative verbal memory consolidation compared to equal periods of daytime wakefulness in GSC and (ii) a significantly enhanced procedural memory consolidation compared to equal periods of daytime wakefulness and night-time sleep in PI. Across retention intervals of daytime wakefulness, no differences between the experimental groups were observed. This pattern of results suggests that healthy sleep fosters the consolidation of new memories, and that this process is impaired for procedural memories in patients with PI. Future work is needed to investigate the impact of treatment on improving sleep and memory.

    This document gives an overview of the scientific results obtained under the DOE grant, and references the journal articles which give more complete descriptions of the various topics. Recently, the research has been focused on 2-dimensional vortices and turbulence: experiments using a new camera-diagnosed electron plasma apparatus have given surprising results which both clarify and challenge theories. Here, the crossfield E x B flow of the electron plasma is directly analogous to the 2-d flow of an ideal fluid such as water, and may also give insight into more complicated poloidal flows exhibited in toroidal plasmas. The shear-flow instabilities, turbulence, and vortices can be accurately observed, and the free relaxation of this turbulence has been characterized. The physical processes underlying the complicated turbulent evolution can also be studied in more controlled near-linear regimes. The original experimental focus of this program was on radial particle transport from applied external field asymmetries. Here, this research program clearly identified the importance of the collective response of the plasma, giving smaller fields from shielding, or enhanced fields from resonant modes. Experiments and theory work have also elucidated the flow of a plasma along the magnetic field. Finally, some theory was pursued for direct application to fusion plasmas, and to gravitating gas clouds in astrophysics. This program was highly successful in clarifying basic plasma transport processes.

    Characteristic of cyclic loading due to passing wheels is associated with one-way loading without stress reversal, which includes a simultaneous cyclic variation of vertical normal stress and horizontal normal stress lasting for a long period of time and generally takes place in partially-drained conditions. Therefore, it is of great practical relevance to study the deformation behaviour according to the characteristic of traffic loading. In this work, a series of one-way stress-controlled cyclic triaxial tests with a simultaneous variation of the vertical and horizontal stress components during cyclic loading were conducted to investigate the deformation behaviour of naturalK0-consolidated soft clay in partially-drained conditions. Test results demonstrate that not only the deviator part of the stress rules accumulation but also the volumetric part significantly contributes. While the deviator part of the stress amplitude is held constant, the increase amplitude of cyclic confining pressure will promote the development of both permanent volumetric strain and axial strain significantly. Furthermore, the effects of cyclic confining pressure on the deformation of naturalK0-consolidated soft clay was quantified. Finally, an empirical formula for permanent axial strain considering the effects of cyclic confining pressure was proposed which can be used for feasibility studies or for the preliminary design of foundations on K0-consolidated soft clay subjected to traffic loading.

    In order to relieve the conflict of increasing economy and population and decreasing land quantity and quality, it is necessary to carry out land consolidation planning from the aspect of sustainable development , particularly in Hebei Province where grain and cotton of China are mainly produced. Based on land resources and topography and geomorphology characteristics in Hebei Province, sustainable land consolidation pattern in Hebei Province was identified. The ecosystem service value before and after the land consolidation was calculated by monetizing the ecosystem service functions. Effect of different sustainable land consolidation pattern was explored by the economic value and ecosystem service value evaluation. The typical pattern of land consolidation project included land leveling mode, irrigation mode, and drainage mode. Ecosystem service values of 5 land use types (garden, woodland, grassland, wetland, water area) other than farmland were decreasing with the increase of economic value. Four of individual ecosystem service functions (food production, soil formation and protection, the value of the raw materials, gas regulation) values retained and improved while five of them (water conservation, waste treatment, climate regulation, recreational and cultural value, biodiversity conservation) reduced a lot. The ecosystem service value of land therefore severely lost. The economic value of land consolidation in the hilly region improved little while its ecosystem service value decreased a lot. The economic value of land consolidation in the plateau area improved a lot by paying the price of the ecosystem service value. The mainly conclusions were as followings: the sustainable land consolidation project of Hebei Province totally benefits. The improvement of economic benefits, in other words, was larger than the decrease of ecological benefits. But it was always replaced more economic benefits with the cost of ecosystem services value.

  20. Study of B Meson Decays to ppbarh Final States

    2006-03-22

    B mesons are unique among well-established non-quarkonium mesons in their ability to decay into baryons. Baryonic B decays offer a wide range of interesting areas of study: they can be used to test our theoretical understanding of rare decay processes involving baryons, search for direct CP violation and study low-energy QCD. This thesis presents measurements of branching fractions and a study of the decay dynamics of the charmless three-body decays of B meson into p{bar p}h final states, where h = {pi}{sup +}, K{sup +}, K{sub S}{sup 0}, K*{sup 0} or K*{sup +}. With a sample of 232 million {Upsilon}(4S) {yields} B{bar B} events collected with the BaBar detector, we report the first observation of the B {yields} p{bar p}K*{sup 0} decay, and provide improved measurements of branching fractions of the other modes. The distribution of the three final-state particles is of particular interest since it provides dynamical information on the possible presence of exotic intermediate states such as the hypothetical pentaquark states {Theta}*{sup ++} and {Theta}{sup +}in the m{sub pK{sup +}} and m{sub pK{sub S}{sup 0}} spectra, respectively, or glueball states (such as the tensor glueball f{sub J}(2220)) in the m{sub p{bar p}} spectrum. No evidence for exotic states is found and upper limits on the branching fractions are set. An enhancement at low p{bar p} mass is observed in all the B {yields} p{bar p}h modes, and its shape is compared between the decay modes and with the shape of the time-like proton form factor. A Dalitz plot asymmetry in B {yields} p{bar p}K{sup +} mode suggests dominance of the penguin amplitude in this decay and disfavors the possibility that the low mass p{bar p} enhancement originates from the presence of a resonance below threshold (such as the recently seen baryonium candidate at 1835 MeV/c{sup 2}). We also identify decays of the type B {yields} X{sub c{bar c}}h {yields} p{bar p}h, where h = K{sup +}, K{sub S}{sup 0}, K*{sup 0} or K*{sup +}, and X

As resting state has been demonstrated with function of memory consolidation and sub-regions of DMN, the hippocampus and medial prefrontal cortex, are the key regions of memory consolidation, we hypothesize that the DMN is the core structure of sleep-dependent memory consolidation. With the high resolution in temporal and spatial domain of simultaneous EEG-fMRI, we will study the neural mechanisms of the DMN-involved memory consolidation, which includes: 1) describing the dynamic process of memory consolidation based on the EEG source localization and cross-frequency coupling analysis; 2) distinguishing the functional connectivity of DMN during resting and sleep states based on the sliding time-window and module analysis to reveal the basic principles of memory enhancement within the iteration of day and night;3) revealing the influences of types of memory and sleep stages in memory consolidation

    Combining Biot's consolidation theory with contaminant transport theory, a one-dimensional mathematical model for contaminant transport in clay layers is developed. The distinct feature of the model is that the effect of soil deformation on contaminant transport is considered. Analytic solution of the model is sought by using reasonable assumptions, with the attenuation of contaminated fountain concentration being taken into account. The concentration distribution of a major contaminant in the Taihu dredged sediment field is calculated, and the results indicate that the depth of contaminant transport with soil consolidation is smaller than that without soil consolidation.%在比奥固结理论和污染物运移理论相结合的基础上,提出污染物在黏土防渗层中运移转化的一维数学模型,该模型的最大特点是考虑了土体受力变形对污染物运移的影响.在合理简化的基础上给出考虑污染源浓度随时间衰减情况下,污染物运移模型的解析解,对太湖疏浚堆场中底泥所含主要污染物的浓度随时空的分布进行模拟计算,并将模拟结果与不考虑土体压缩变形的污染物运移情况作比较.结果表明考虑土层固结后污染物运移的深度要小于不考虑土层固结的情况.

    Effluent concentration distributions from the waste water discharge of the Kraft Division Mill, Consolidated Paper Company, into the Wisconsin River at Wisconsin Rapids, Wisconsin, is investigated. Effluent concentrations were determined from measurements of the temperature distribution, using temperature as a tracer. Measurements of the velocity distribution in the vicinity of the outfall were also made. Due to limitations in the extent of the field observations, the analysis and comparison of the measurements is limited to the region within about 300 feet from the outfall. Effects of outfall submergence, of buoyancy and momentum of the effluent and of the pattern and magnitude of river currents on these characteristics are considered.

  5. Pulsed Neutron Scattering Studies of Strongly Fluctuating solids, Final Report

    2006-06-22

    The conventional description of a solid is based on a static atomic structure with small amplitude so-called harmonic fluctuations about it. This is a final technical report for a project that has explored materials where fluctuations are sufficiently strong to severely challenge this approach and lead to unexpected and potentially useful materials properties. Fluctuations are enhanced when a large number of configurations share the same energy. We used pulsed spallation source neutron scattering to obtain detailed microscopic information about structure and fluctuations in such materials. The results enhance our understanding of strongly fluctuating solids and their potential for technical applications. Because new materials require new experimental techniques, the project has also developed new techniques for probing strongly fluctuating solids. Examples of material that were studied are ZrW2O8 with large amplitude molecular motion that leads to negative thermal expansion, NiGa2S4 where competing interactions lead to an anomalous short range ordered magnet, Pr1- xBixRu2O7 where a partially filled electron shell (Pr) in a weakly disordered environment produces anomalous metallic properties, and TbMnO3 where competing interactions lead to a magneto-electric phase. The experiments on TbMnO3 exemplify the relationship between research funded by this project and future applications. Magneto-electric materials may produce a magnetic field when an electric field is applied or vise versa. Our experiments have clarified the reason why electric and magnetic polarization is coupled in TbMnO3. While this knowledge does not render TbMnO3 useful for applications it will focus the search for a practical room temperature magneto-electric for applications.

  6. A method of determining nonlinear large strain consolidation parameters of dredged clays

    Yu-peng CAO

    2014-04-01

    Full Text Available A method of obtaining the large strain consolidation parameters of dredged clays considering the influence of the initial water content is investigated in this study. According to the test results of remolded clays with high initial water contents reported by Hong et al. (2010, a relationship between the void ratio (e and effective stress (σ' is established. Furthermore, based on the available permeability data from the literature, a new relationship between the permeability coefficient (k and the ratio (e/eL of the void ratio to the void ratio at the liquid limit (eL is proposed. The new proposed expression considering the initial water content improves the e-k equation established by Nagaraj et al. (1994. Finally, the influence of the initial void ratio and effective stress on the large strain consolidation coefficient g(e defined by Gibson et al. (1981 and k/(1+e in large strain analysis is discussed. The results show that, under a constant effective stress, the value of k/(1+e increases with the initial void ratio. The large strain consolidation coefficient shows the law of segmentation change, which decreases with the increase of the effective stress when the effective stress is less than the remolded yield stress, but increases rapidly with the effective stress when the effective stress is larger than the remolded yield stress.

    Sustainable farmland consolidation covers ecology, economy and society, which means, its only goal is to protect eco-environment, in accordance with public benefits and economic laws. China is still a developing country, facing capital-lacking, an important but difficult problem, while sustainable farmland consolidation will need more money than common farmland consolidation. To solve the problem, this paper put forward and designed a new financing mode for farmland consolidation: BOT(Build-Operate-Transfer), which can effectively solve the financing problem and investment reclamation by the way of concession, and make sustainable farmland consolidation be realized in China.

    Full Text Available The involvement of the serotonin system in the pathophysiology of schizophrenia has been elucidated by experiments with hallucinogens. Application of a hallucinogen to humans leads to changes in perception, cognition, emotions and induction of psychotic-like symptoms that resemble symptoms of schizophrenia. In rodent studies, their acute administration affects sensorimotor gating, locomotor activity, social behavior and cognition including working memory, the phenotypes are considered as an animal model of schizophrenia. The complexity and singularity of human cognition raises questions about the validity of animal models utilizing agonists of 5-HT2A receptors. The present study thus investigated the effect of psilocin on memory acquisition, reinforced retrieval and memory consolidation in rats. Psilocin is a main metabolite of psilocybin acting as an agonist at 5-HT2A receptors with a contribution of 5-HT2C and 5-HT1A receptors. First, we tested the effect of psilocin on the acquisition of a Carousel maze, a spatial task requiring navigation using distal cues, attention and cognitive coordination. Psilocin significantly impaired the acquisition of the Carousel Maze at both doses (1 and 4 mg/kg. The higher dose of psilocin blocked the learning processes even in an additional session when the rats received only saline. Next, we examined the effect of psilocin on reinforced retrieval and consolidation in the Morris water maze (MWM. The dose of 4 mg/kg disrupted reinforced retrieval in the Morris water maze. However, the application of a lower dose was without any significant effect. Finally, neither the low nor high dose of psilocin injected post-training caused a deficit in memory consolidation in the MWM. Taken together, the psilocin dose dependently impaired the acquisition of the Carousel maze and reinforced retrieval in MWM; however, it had no effect on memory consolidation.

  10. FINAL REPORT ON THE AQUATIC MERCURY ASSESSMENT STUDY

    Energy Technology Data Exchange (ETDEWEB)

    Halverson, N

    2008-09-30

    In February 2000, the United States Environmental Protection Agency (EPA) Region 4 issued a proposed Total Maximum Daily Load (TMDL) for total mercury in the middle and lower Savannah River. The initial TMDL, which would have imposed a 1 ng/l mercury limit for discharges to the middle/lower Savannah River, was revised to 2.8 ng/l in the final TMDL released in February 2001. The TMDL was intended to protect people from the consumption of contaminated fish, which is the major route of mercury exposure to humans. The most bioaccumulative form of mercury is methylmercury, which is produced in aquatic environments by the action of microorganisms on inorganic mercury. Because of the environmental and economic significance of the mercury discharge limits that would have been imposed by the TMDL, the Savannah River Site (SRS) initiated several studies concerning: (1) mercury in SRS discharges, SRS streams and the Savannah River, (2) mercury bioaccumulation factors for Savannah River fish, (3) the use of clams to monitor the influence of mercury from tributary streams on biota in the Savannah River, and (4) mercury in rainwater falling on the SRS. The results of these studies are presented in detail in this report. The first study documented the occurrence, distribution and variation of total and methylmercury at SRS industrial outfalls, principal SRS streams and the Savannah River where it forms the border with the SRS. All of the analyses were performed using the EPA Method 1630/31 ultra low-level and contaminant-free techniques for measuring total and methylmercury. Total mercury at National Pollutant Discharge Elimination System (NPDES) outfalls ranged from 0.31-604 ng/l with a mean of 8.71 ng/l. Mercury-contaminated groundwater was the source for outfalls with significantly elevated mercury concentrations. Total mercury in SRS streams ranged from 0.95-15.7 ng/l. Mean total mercury levels in the streams varied from 2.39 ng/l in Pen Branch to 5.26 ng/l in Tims Branch

    2015-01-01

    A simplified method is presented for predicting consolidation settlement of soft ground improved by floating soil−cement column on the basis of double soil-layer consolidation theory. Combining the axisymmetric consolidation model and equal strain assumption, the governing equation was derived for the consolidation of clayey subsoil reinforced by soil−cement column. By modifying the boundary condition of the interface between the improved layer and underlying layer on seepage and pore-water pressure, the analytical solution of consolidation of soft ground improved by floating soil−cement column was developed under depth-dependent ramp load. The results of the parameter analysis of consolidation behavior show that the consolidation rate is closely related with the depth replacement ratio by the column and the permeability of upper layer. The influence of column−soil constrained modulus ratio and radius ratio of the influence zone to the column on consolidation is also affected by depth replacement ratio. The column−soil total stress ratio increases with time and approaches the final value accompanied with the dissipation of excess pore water pressure.

  12. Memory Consolidation and Neural Substrate of Reward

    Redolar-Ripoll, Diego

    2012-08-01

    Full Text Available The aim of this report is to analyze the relationships between reward and learning and memory processes. Different studies have described how information about rewards influences behavior and how the brain uses this reward information to control learning and memory processes. Reward nature seems to be processed in different ways by neurons in different brain structures, ranging from the detection and perception of rewards to the use of information about predicted rewards for the control of goal-directed behavior. The neural substrate underling this processing of reward information is a reliable way of improving learning and memory processes. Evidence from several studies indicates that this neural system can facilitate memory consolidation in a wide variety of learning tasks. From a molecular perspective, certain cardinal features of reward have been described as forms of memory. Studies of human addicts and studies in animal models of addiction show that chronic drug exposure produces stable changes in the brain at the cellular and molecular levels that underlie the long-lasting behavioral plasticity associated with addiction. These molecular and cellular adaptations involved in addiction are also implicated in learning and memory processes. Dopamine seems to be a critical common signal to activate different genetic mechanisms that ultimately remodel synapses and circuits. Despite memory is an active and complex process mediated by different brain areas, the neural substrate of reward is able to improve memory consolidation in a several paradigms. We believe that there are many equivalent traits between reward and learning and memory processes.

    Genetic and stress-related factors interact to foster mental disorders, possibly through dysfunctional learning. In a previous study we reported that a temporary experience of reduced food availability increases forced swim (FS)-induced helplessness tested 14days after a first experience in mice of the standard inbred C57BL/6(B6) strain but reduces it in mice of the genetically unrelated DBA/2J (D2) strain. Because persistence of FS-induced helplessness influences adaptive coping with stress challenge and involve learning processes the present study tested whether the behavioral effects of restricted feeding involved altered consolidation of FS-related learning. First, we demonstrated that restricted feeding does not influence behavior expressed on the first FS experience, supporting a specific effect on persistence rather then development of helplessness. Second, we found that FS-induced c-fos expression in the infralimbic cortex (IL) was selectively enhanced in food-restricted (FR) B6 mice and reduced in FR D2 mice, supporting opposite alterations of consolidation processes involving this brain area. Third, we demonstrated that immediate post-FS inactivation of IL prevents 24h retention of acquired helplessness by continuously free-fed mice of both strains, indicating the requirement of a functioning IL for consolidation of FS-related learning in either mouse strain. Finally, in line with the known role of IL in consolidation of extinction memories, we found that restricted feeding selectively facilitated 24h retention of an acquired extinction in B6 mice whereas impairing it in D2 mice. These findings support the conclusion that an experience of reduced food availability strain-specifically affects persistence of newly acquired passive coping strategies by altering consolidation of extinction-like inhibitory learning.

    The dewatering and consolidation experiment of sludge from environmental is carried out by using small-sized geo-textile tubes. The influences of different structural characteristics of geotextile tubes such as weaving method,weaving structure and aperture,and dosages of dewatering agent on its dewatering and consolidation effects are studied. The results show that the dewatering and consolidation effect of the woven twill geotextile tube with 0.5 mm aperture is better. And the effect of cationic polyacrylamide (CPAM) in the dosage of 0.6~1.0 g/kg is also better. But the best dosage must be adjusted according to the different conditions in the practical projects.%利用小型土工管袋进行环保疏浚淤泥脱水固结试验,研究土工管袋的不同结构特征(织造方式、织造结构、等效孔径)和脱水药剂用量对环保疏浚淤泥脱水固结的影响。试验结果表明:脱水药剂阳离子聚丙烯酰胺(CPAM)在0.6~1.0 g/kg投加量下配合0.5 mm等效孔径机织斜纹土工管袋组合,在疏浚淤泥脱水固结方面表现较好,但脱水药剂具体最佳用量需在实际工程中根据不同工况做适当调整。

    1985-02-01

    A series of experiments were conducted on uranium mill tailings from the tailings pile in Grand Junction, Colorado, to determine their consolidation characteristics. Three materials (sand, sand/slimes mix, slimes) were loaded under saturated conditions to determine their saturated consolidated behavior. During a separate experiment, samples of the slimes material were kept under a constant load while the pore pressure was increased to determine the partially saturated consolidation behavior. Results of the saturated tests compared well with published data. Sand consolidated the least, while slimes consolidated the most. As each material consolidated, the measured hydraulic conductivity decreased in a linear fashion with respect to the void ratio. Partially saturated experiments with the slimes indicated that there was little consolidation as the pore pressure was increased progressively above 7 kPa. The small amount of consolidation that did occur was only a fraction of the amount of saturated consolidation. Preliminary measurements between pore pressures of 0 and 7 kPa indicated that measurable consolidation could occur in this range of pore pressure, but only if there was no load. 13 references, 13 figures.

    To study the combustion stability and safety of consolidation propellants under the conditions of variable combustion-chamber volume and to discuss the effects of different surface-treatment methods on progressive burning,high temperature solvent vapor of alcohol/acetone were used to consolidate double-base oblate sphere propellant standard grains plasticized with tri-ethyeneglycol dinitrate (TEGN ) to propellants charge with high compaction density of 1 .3 5 g·cm-3 after pre-deconsolidation treatment.The obtained consolidated charges were coated by pure nitrocellulose gel,mixed nitrocellulose gel containing ignition sensitizer and mixed nitro-cellulose gel containing the deterrents,respectively.Interrupted burning experiments of consolidated propellant charges were carried out in a semi-closed test rig with variable volume, and the pressure-time history of gas generation during the interrupted burning was recorded by the pressure transducer.The effect of different surface treatment method on the burning progressivity of prepared samples was discussed based on the deduced dynamic vivacity data. Compared with coated consolidated with pure nitrocellulose gel,it is easy to be ignited for the samples coated by the mixed nitrocellulose gel containing ignition sensitizer.In contrast,the prepared samples coated by deterred nitrocellulose gel indicates an ignition delay;the peak of dynamic vivacity decreases a little,and the progressive burning is good.Results show that appropriate surface treatment method can inhibit the initial dynamic vivacity of consolidated charges and obtain the burning progressivity.%为研究压实装药在变容情况下的动态燃烧稳定性、安全性能及不同表面处理方法对动态燃烧渐增性能的影响,将太根小粒药表面进行解体预处理后,采用乙醇/丙酮高温热蒸汽软化法将其压实成堆积密度为1.35 g·cm-3的药柱,再进行表面处理,得到待测的压实药柱样品。利用设计自制

    Full Text Available Exercise has been shown to reduce age-related losses in cognitive function including learning and memory, but the mechanisms underlying this effect remain poorly understood. Memory formation occurs in stages that include an initial acquisition phase, an intermediate labile phase, and then a process of consolidation which leads to long term memory formation. An effective way to examine the mechanism by which exercise improves memory is to introduce the intervention (exercise, post-acquisition, making it possible to selectively examine memory storage and consolidation. Accordingly we evaluated the effects of post-trial exercise (10 minutes on a treadmill on memory consolidation in aged canines both right after, an hour after, and twenty-four hours after acute exercise training in concurrent discrimination, object location memory (OLM and novel object recognition (NOR tasks. Our study shows that post-trial exercise facilitates memory function by improving memory consolidation in aged animals in a time-dependent manner. The improvements were significant at twenty-four hour post exercise and not right after or one hour after exercise. Aged animals were also tested following chronic exercise (10 min/day for 14 consecutive days on OLM or till criterion were reached (for reversal learning task. We found improvements from a chronic exercise design in both the object location and reversal learning tasks. Our studies suggest that mechanisms to improve overall consolidation and cognitive function remain accessible even with progressing age and can be re-engaged by both acute and chronic exercise.

    2015-03-01

    Full Text Available The paper presents a comprehensive review of the know-how for developing the systems consolidity theory for modeling, analysis, optimization and design in fully fuzzy environment. The solving of systems consolidity theory included its development for handling new functions of different dimensionalities, fuzzy analytic geometry, fuzzy vector analysis, functions of fuzzy complex variables, ordinary differentiation of fuzzy functions and partial fraction of fuzzy polynomials. On the other hand, the handling of fuzzy matrices covered determinants of fuzzy matrices, the eigenvalues of fuzzy matrices, and solving least-squares fuzzy linear equations. The approach demonstrated to be also applicable in a systematic way in handling new fuzzy probabilistic and statistical problems. This included extending the conventional probabilistic and statistical analysis for handling fuzzy random data. Application also covered the consolidity of fuzzy optimization problems. Various numerical examples solved have demonstrated that the new consolidity concept is highly effective in solving in a compact form the propagation of fuzziness in linear, nonlinear, multivariable and dynamic problems with different types of complexities. Finally, it is demonstrated that the implementation of the suggested fuzzy mathematics can be easily embedded within normal mathematics through building special fuzzy functions library inside the computational Matlab Toolbox or using other similar software languages.

    The data gathered in Egypt in Phase I of the program indicated favorable wind energy possibilities along the Mediterranean Coast west of Alexandria and along the Red Sea south of Suez. There did not appear to be inland areas of high promise. It was decided that in Phase II, several continuous wind recording instruments would be established on the North Coast and Red Sea Coasts. Locations finally selected for the North Coast (South Coast of the Mediterranean) were distributed from Mersa Matruh to Borg El Arab, a coastal community about seventy kilometers west of Alexandria. The recorded data from the monitoring stations are presented.

  4. SOME ASPECTS REGARDING THE THEORIES OF CONSOLIDATED FINANCIAL STATEMENTS

    2015-04-01

    Full Text Available Although accounts consolidation was used in practice from the early 1900’s its theoretical basis were developed later in concordance with the rise of concepts like “entity” and “group”. The aim of this article is to examine the literature in the accounting field regarding the consolidation theories developed over the years. In order to discuss the different opinions regarding the consolidation theories we used the descriptive approach. As a result we tried to explain how these theories appeared and developed, respectively what consequences have their use in preparing consolidated financial statements. The results of the study suggest that every theory has certain aspects which differentiate it from the others in terms of recognition of subsidiary income and reporting net assets of the subsidiary. However, from all theories analyzed, the entity theory takes into account several guidelines of maximum importance when preparing consolidated financial statements: “You can’t own yourself!”, “You can’t owe yourself money!”, “You can’t make money selling to yourself.”

  5. Biofuels Sustainability Criteria. Relevant issues to the proposed Directive on the promotion of the use of energy from renewable sources. (COM(2008) 30 final). Consolidated study

    The role envisioned for liquid biofuels for transport has come under increased scrutiny in the past year or two, due to the potential social and environmental impacts associated with scaling up biofuels production and use from its low level - currently representing about 1% of transport fuels globally. The proposed EU Directive setting a target of 10% biofuels in transport sector by 2020 has therefore raised a number of concerns. The concerns about sustainability are addressed within the proposed Directive through criteria related mainly to GHG emissions, but also to biodiversity and other environmental impacts. The use of first generation biofuels in temperate climates is land-intensive and inefficient in technical terms, whereas first generation biofuels in tropical climates and second generation biofuels in general - offer a much more effective use of land resources. The use of GHG reduction criteria can provide incentives for producers to rely on the most productive feedstocks when sourcing biofuels for the EU market, which will often mean import of biofuels. A threshold of 50% or more would tend to eliminate many of the first generation biofuels produced in temperate climates. Member States should be encouraged to link financial incentives to the GHG reduction capabilities. Moreover, such incentives could be better linked to development cooperation in the case of imports, so as to insure that Least Developed Countries (i.e. in Africa) can gain access to larger markets rather than only the major producers such as Brazil. The calculation of GHG emissions associated with biofuels is complicated by the addition of factors associated with land use change, since the GHG impacts of land use change are beset by uncertainty both in physical terms as well as in the attribution of particular changes to production of particular biofuels. A further complication is introduced when indirect land use changes are incorporated, since these occur through combinations of market forces, illegal land use transformation, and regulatory efforts. Some improvements can be made to existing methodologies in the proposed Directive by being more precise on the system boundaries associated with particular biofuels. More analysis and research is needed in order to improve the incorporation of land use change into estimates of GHG emissions from biofuels. Use of degraded lands for bioenergy and biofuels production offers an interesting option for combining expanded energy production with decreases in GHG emissions by improving land quality as well as by fuel substitution. The incentives for doing so, however, often need to be high, since biomass feedstock producers will always favour higher quality lands, other things being equal. Harmonisation with other sustainability schemes is important in order to create more effective markets and provide clearer signals to producers and consumers. Harmonisation efforts need to be undertaken in future revisions of the Directive, both with major producing countries such as the U.S. and Brazil, but also with respect to existing UNFCCC procedures related to CDM, REDD, and other programmes

    Femtoscopy is a technique enabling measurements of the space-time characteristics of particle-emitting sources. However, the femtoscopic analysis is also sensitive to the interaction cross-section. In this paper we show the first preliminary measurements of $\\rm K^0_SK^{\\pm}$ correlation functions in Pb-Pb collisions at $\\sqrt{s_{\\rm NN}}=5.02$ TeV. These correlations originate from the final-state interactions which proceed through the $a_0(980)$ resonance only and can be employed to constrain its parameters. A similar approach can be applied to baryon pairs to extract the unknown interaction cross-sections for some (anti-)baryon-(anti-)baryon pairs. We show baryon--baryon and baryon--anti-baryon correlation functions of protons and lambdas, as well as discuss shortly the fitting method.

    Full Text Available The contributions made by theory on democratic consolidation in Eastern Europe are also pertinent to analysis of processes of democratization and democratic consolidation in other areas, such as sub-Saharan Africa. The parameters of analysis highlight the importance of a strong state (organized, with legitimated institutions and a structured society (whether multiethnic or not as necessary conditions for democratization. On the assumption that the colonizing powers basically used two models –the French assimilationist model and the British indirect government model– the study of how these conditions were fulfilled in various sub-Saharan states leads to two conclusions: the first, the possibility of a process of democratization in those states where European (French colonization produced a total assimilation of the colonized society, including above all the colonizer’s political values; and the second, the possibility of processes of democratization in states produced by British colonization where the indigenous structures and those of the metropolis were superimposed, a phenomenon which allowed the application of democratic values by legitimated local institutions.

    Soil consolidation would induce variations of its transport coefficients such as hydraulic conductivity and diffusion coefficient. This paper presents a study of the influence of barrier consolidation on transport coefficients,and a 3D transport model based on mixture theory is proposed for describing the liners that involve circular defects in the geomembrane.The elastoplastic ALPHA model is revised by using the spatially mobilized plane (SMP) criterion for simulating the deformation of the soils.Then,the 3D model coupling the nonlinear consolidation and contaminant advection-diffusion is solved using the finite element software ABAQUS.The results show that the importance of reducing the defect size in the geomembrane and the liner porosity to control the contaminant concentration increase.

    The use of higher oxidation states of americium in partitioning from the lanthanides is under continued investigation by the sigma team. This is based on the hypothesis that Am(VI) can be produced and remain stable in irradiated first cycle raffinate solution long enough to perform solvent extraction for separations. The stability of Am(VI) to autoreduction was measured using millimolar americium concentrations in a 1-cm cell with a Cary 6000 UV/Vis spectrophotometer for data acquisition. At millimolar americium concentrations, Am(VI) is stable enough against its own autoreduction for separations purposes. A second major accomplishment during FY14 was the hot test. Americium oxidation and extraction was performed using a centrifugal contactor-based test bed consisting of an extraction stage and two stripping stages. Sixty-three percent americium extraction was obtained in one extraction stage, in agreement with batch contacts. Promising electrochemical oxidation results have also been obtained, using terpyridine ligand derivatized electrodes for binding of Am(III). Approximately 50 % of the Am(III) was oxidized to Am(V) over the course of 1 hour. It is believed that this is the first demonstration of the electrolytic oxidation of americium in a non-complexing solution. Finally, an initial investigation of Am(VI) extraction using diethylhexylbutyramide (DEHBA) was performed.

  10. Sleep deprivation impairs consolidation of cued fear memory in rats.

    Full Text Available Post-learning sleep facilitates negative memory consolidation and also helps preserve it over several years. It is believed, therefore, that sleep deprivation may help prevent consolidation of fearful memory. Its effect, however, on consolidation of negative/frightening memories is not known. Cued fear-conditioning (CuFC is a widely used model to understand the neural basis of negative memory associated with anxiety disorders. In this study, we first determined the suitable circadian timing for consolidation of CuFC memory and changes in sleep architecture after CuFC. Thereafter, we studied the effect of sleep deprivation on CuFC memory consolidation. Three sets of experiments were performed in male Wistar rat (n=51. In experiment-I, animals were conditioned to cued-fear by presenting ten tone-shock paired stimuli during lights-on (7 AM (n=9 and lights-off (7 PM (n=9 periods. In experiment-II, animals were prepared for polysomnographic recording (n=8 and changes in sleep architecture after CuFC was determined. Further in experiment-III, animals were cued fear-conditioned during the lights-off period and were randomly divided into four groups: Sleep-Deprived (SD (n=9, Non-Sleep Deprived (NSD (n=9, Stress Control (SC (n=9 and Tone Control (n=7. Percent freezing amount, a hallmark of fear, was compared statistically in these groups. Rats trained during the lights-off period exhibited significantly more freezing compared to lights-on period. In CuFC trained animals, total sleep amount did not change, however, REM sleep decreased significantly. Further, out of total sleep time, animals spent proportionately more time in NREM sleep. Nevertheless, SD animals exhibited significantly less freezing compared to NSD and SC groups. These data suggest that sleep plays an important role in the consolidation of cued fear-conditioned memory.

    Purpose To compare the antitumor efficacy of three different anthracyclines in combination with cytarabine and etoposide in adult patients with newly diagnosed acute myeloid leukemia (AML). Patients and Methods We randomly assigned 2,157 patients (age range, 15 to 60 years) to receive intensive induction-consolidation chemotherapy containing either daunorubicin, idarubicin, or mitoxantrone. After achieving complete remission (CR), patients were assigned to undergo either allogeneic or autologous stem-cell transplantation (SCT), depending on the availability of a sibling donor. Results The overall CR rate (69%) was similar in the three groups. Autologous SCT was performed in 37% of cases in the daunorubicin arm versus only 29% and 31% in mitoxantrone and idarubicin, respectively (P < .001). However, the disease-free survival (DFS) and survival from CR were significantly shorter in the daunorubicin arm: the 5-year DFS was 29% versus 37% and 37% in mitoxantrone and idarubicin, respectively. The proportion of patients who underwent allogeneic SCT (22%) was equivalent in the three treatment groups, and the outcome was similar as well: the 5-year overall survival rates were 34%, 34%, and 31%, respectively. Conclusion In adult patients with AML who do not receive an allogeneic SCT, the use of mitoxantrone or idarubicin instead of daunorubicin enhances the long-term efficacy of chemotherapy.

    2014-10-01

    The Washoe Tribe of Nevada and California was awarded funding to complete the Washoe Tribe Alternative Energy Feasibility Study project. The main goal of the project was to complete an alternative energy feasibility study. This study was completed to evaluate “the potential for development of a variety of renewable energy projects and to conduct an alternative energy feasibility study that determines which alternative energy resources have the greatest economic opportunity for the Tribe, while respecting cultural and environmental values” (Baker-Tilly, 2014). The study concluded that distributed generation solar projects are the best option for renewable energy development and asset ownership for the Washoe Tribe. Concentrating solar projects, utility scale wind projects, geothermal, and biomass resource projects were also evaluated during the study and it was determined that these alternatives would not be feasible at this time.

  6. Consolidation Theory for a Stone Column Composite Foundation under Multistage Loading

    Directory of Open Access Journals (Sweden)

    Shenggen Huang

    2016-01-01

    Full Text Available The consolidation theories considering instant load cannot fully reveal the consolidation mechanism of a stone column composite foundation used in the expressway embankments due to the time effect of loading; that is, the expressway embankments are often constructed in several stages for a long time. Meanwhile, owing to the special property that the pile-soil stress ratio is larger than 1, the consolidation theory for sand drain well foundation cannot be used directly in the consolidation analysis of stone column composite foundation. Based on the principle that the vertical load applied on the composite foundation is shared by the stone column and the surrounding soil, the governing solutions for the stone column composite foundation under a multistage load are established. By virtue of the separation of variables, the corresponding solutions of degree of consolidation for loading stage and maintaining load stage are derived separately. According to the Carrillo theorem, the solution for the average total degree of consolidation of entire composite foundation is also obtained. Finally, the reasonableness of the present solution has been verified by comparing the consolidation curve calculated by the present solution with that measured by site test.

  8. Shockwave Consolidation of Nanostructured Thermoelectric Materials

    Science.gov (United States)

    Prasad, Narasimha S.; Taylor, Patrick; Nemir, David

    2014-01-01

    Nanotechnology based thermoelectric materials are considered attractive for developing highly efficient thermoelectric devices. Nano-structured thermoelectric materials are predicted to offer higher ZT over bulk materials by reducing thermal conductivity and increasing electrical conductivity. Consolidation of nano-structured powders into dense materials without losing nanostructure is essential towards practical device development. Using the gas atomization process, amorphous nano-structured powders were produced. Shockwave consolidation is accomplished by surrounding the nanopowder-containing tube with explosives and then detonating. The resulting shock wave causes rapid fusing of the powders without the melt and subsequent grain growth. We have been successful in generating consolidated nano-structured bismuth telluride alloy powders by using the shockwave technique. Using these consolidated materials, several types of thermoelectric power generating devices have been developed. Shockwave consolidation is anticipated to generate large quantities of nanostructred materials expeditiously and cost effectively. In this paper, the technique of shockwave consolidation will be presented followed by Seebeck Coefficient and thermal conductivity measurements of consolidated materials. Preliminary results indicate a substantial increase in electrical conductivity due to shockwave consolidation technique.

    1997-07-01

    For planning authorities to address renewable energy through development plan policies and in the development control process, it is important to have clear and reliable information on the resource potential within their area. A number of studies have been undertaken in England and Wales to assess the potential for the development and utilisation of renewable energy resources. The studies have addressed the practicalities of how and why a certain resource might be suitable for exploitation in a particular county or region, in conjunction with consideration of the specific planning and environmental issues which may arise. The Eastern Region Renewable Energy Planning Study (ERREPS) is one of the last of these studies to be commissioned and, together with a concurrent study of the Lancashire and Yorkshire area, will substantially complete study coverage of England and Wales. The study area comprises the counties of Bedfordshire, Buckinghamshire, Cambridgeshire, Essex, Hertfordshire, Norfolk and Suffolk. It generally coincides with the area covered by Eastern Electricity. The area covers the majority of the land north of the River Thames to The Wash. (author)

    1983-03-31

    A randomized controlled experimental study of the use x-ray pelvimetry in 151 hospitals in seven PSROs across the United States from June 1977 through March 1982 was conducted. The study was designed to test the impact of a physician educational intervention program on the utilization of a diagnostic procedure of questionable efficacy. Further, special studies were designed to assess substitution and quality effects by measuring changes in the utilization of caesarean section, electronic fetal monitoring and ultrasound; to assess the degree to which justification for the use of pelvimetry is recorded on the patient record; and to measure the utilization of pelvimetry in private radiologists' offices. The report contains a narrative discussion of the PSRO program; ancillary services review; a literature review of studies on the efficacy of pelvimetry and educational intervention strategies; and a detailed discussion of the design, methodology, and findings. The results of the study, a substantive drop in the pelvimetry rate in study hospitals vis-a-vis that in control hospitals pre and postintervention demonstrates that physician practice patterns changed due to the educational intervention.

  14. Is autism partly a consolidation disorder?

    Science.gov (United States)

    Femia, Lisa A; Hasselmo, Michael E

    2002-12-01

    Computational modeling has been useful for understanding processes of encoding and consolidation in cortical structures. In particular, this work suggests a role of neuromodulators in setting dynamics for consolidation processes during different stages of waking and sleep. Because autistic individuals show symptoms of a cognitive nature coupled with a high prevalence of comorbid conditions such as epileptiform discharge during sleep and sleep disorders, it is possible that autism could involve a breakdown in consolidation processes, which are essential to build effective cognitive representations of the environment on the basis of individual experiences. In this article, theories of consolidation during different stages of waking and sleep and the role of different neuromodulators in these consolidation processes are reviewed in conjunction with different features of autism, which may be understood in the context of these theories.

    In March 2011, the U.S. Department of Energy (DOE) awarded White Pine County, Nevada, a grant to assess the feasibility of renewable resource-related economic development activities in the area. The grant project included a public outreach and training component and was to include a demonstration project; however, the demonstration project was not completed due to lack of identification of an entity willing to locate a project in White Pine County. White Pine County completed the assessment of renewable resources and a feasibility study on the potential for a renewable energy-focused economic sector within the County. The feasibility study concluded "all resources studied were present and in sufficient quantity and quality to warrant consideration for development" and there were varying degrees of potential economic impact based on the resource type and project size. The feasibility study and its components were to be used as tools to attract potential developers and other business ventures to the local market. White Pine County also marketed the County’s resources to the renewable energy business community in an effort to develop contracts for demonstration projects. The County also worked to develop partnerships with local educational institutions, including the White Pine County School District, conducted outreach and training for the local community.

  6. Differential Training Facilitates Early Consolidation in Motor Learning

    Henz, Diana; Schöllhorn, Wolfgang I.

    2016-01-01

    Current research demonstrates increased learning rates in differential learning (DL) compared to repetitive training. To date, little is known on the underlying neurophysiological processes in DL that contribute to superior performance over repetitive practice. In the present study, we measured electroencephalographic (EEG) brain activation patterns after DL and repetitive badminton serve training. Twenty-four semi-professional badminton players performed badminton serves in a DL and repetitive training schedule in a within-subjects design. EEG activity was recorded from 19 electrodes according to the 10–20 system before and immediately after each 20-min exercise. Increased theta activity was obtained in contralateral parieto-occipital regions after DL. Further, increased posterior alpha activity was obtained in DL compared to repetitive training. Results indicate different underlying neuronal processes in DL and repetitive training with a higher involvement of parieto-occipital areas in DL. We argue that DL facilitates early consolidation in motor learning indicated by post-training increases in theta and alpha activity. Further, brain activation patterns indicate somatosensory working memory processes where attentional resources are allocated in processing of somatosensory information in DL. Reinforcing a somatosensory memory trace might explain increased motor learning rates in DL. Finally, this memory trace is more stable against interference from internal and external disturbances that afford executively controlled processing such as attentional processes.

    1976-11-01

    The work reported is the result of a follow-on program to earlier Very High Temperature Reactor (VHTR) studies. The primary use of the VHTR is to provide heat for various industrial processes, such as hydrocarbon reforming and coal gasification. For many processes the use of an intermediate heat transfer barrier between the reactor coolant and the process is desirable; for some processes it is mandatory. Various intermediate heat exchanger (IHX) concepts for the VHTR were investigated with respect to safety, cost, and engineering design considerations. The reference processes chosen were steam-hydrocarbon reforming, with emphasis on the chemical heat pipe, and steam gasification of coal. The study investigates the critically important area of heat transfer between the reactor coolant, helium, and the various chemical processes.

  8. DOE final report: Studies on the microbial formation of methane

    Energy Technology Data Exchange (ETDEWEB)

    Wolfe, Ralph S.

    2001-04-01

    The microbial formation of methane is carried out by methanogens which are found wherever active anaerobic degradation of organic matter occurs. We developed a procedure for reliable culture of 'Methanococus jannaschii' which yields 8 g wet weight of cells per liter of medium. To initiate a study of proteomics, this organism was grown at two levels of hydrogen partial pressure, very low (650 Pa) and high (178 kPa). When cells were exposed to hydrogen excess conditions, they possessed very low or undetectable levels of four flagella-related polypeptides, whereas, when hydrogen became limiting, these proteins were synthesized. Thus, use of proteomics showed, for the first time, that this methanogen can regulate expression of proteins, and these experiments open the door for general studies of regulation in this hyperthermophile.

    Fast, David E.

    1991-05-01

    This document consists of the appendices for annual report DOE/BP/39461--9 which is summarized as follows. The population of Yakima River spring chinook salmon (Oncorhynchus tschawytscha) has been drastically reduced from historic levels reported to be as high as 250,000 adults (Smoker 1956). This reduction is the result of a series of problems including mainstem Columbia dams, dams within the Yakima itself, severely reduced flows due to irrigation diversions, outmigrant loss in irrigation canals, increased thermal and sediment loading, and overfishing. Despite these problems, the return of spring chinook to the Yakima River has continued at levels ranging from 854 to 9,442 adults since 1958. In October 1982, the Bonneville Power Administration contracted the Yakima Indian Nation to develop methods to increase production of spring chinook in the Yakima system. The Yakima Nation's current enhancement policy attempts to maintain the genetic integrity of the spring chinook stock native to the Yakima Basin. Relatively small numbers of hatchery fish have been released into the basin in past years. The goal of this study was to develop data that will be used to present management alternatives for Yakima River spring chinook. A major objective of this study is to determine the distribution, abundance and survival of wild Yakima River spring chinook. The second major objective of this study is to determine the relative effectiveness of different methods of hatchery supplementation. The last three major objectives of the study are to locate and define areas in the watershed that may be used for the rearing of spring chinook; to define strategies for enhancing natural production of spring chinook in the Yakima River; and to determine the physical and biological limitations on production within the system.

    In the distributed energy production model electricity or heat is produced near the end-user in relatively small units - using very often local renewable energy sources. These are e.g. solar thermal or photovoltaic applications, wind power, fuel cells or other small-scale CHP technologies using e.g. bio-based fuels. Locally produced intermittent renewable electricity can be optimized by storing produced electricity and using it when electricity price is high. Electricity storage is an important part of smart grid development from the perspective of supply-demand flexibility. Heat can be stored as well using e.g. water tank placed either under or above the ground. Distributed energy production technologies are already utilized in domestic residential areas and the trend is emerging. Designing and planning needs to be emphasized in order to build and maintain technically and economically sustainable energy system. The objective of this study is to present the possibilities of distributed energy production and storage technologies. The study highlights available technologies and services of distributed energy production and helps to build up a testbed solution that could lead to demonstration-scale application in near future. This testbed is a part of developing process of Skaftkaerr area where energy efficiency and environmental issues are emphasized. In this report, feasible production and storage technologies are presented in Chapter 2. Chapter 3 introduces economical characteristics of studied technologies. Chapter 4 points out suitable technologies for Skaftkaerr area and presents profitability analysis of these technologies via two cases. Domestic actors in technology value chains are also presented in Chapter 4. Chapter 5 summarizes the study and its findings

    Duval, F

    2012-01-01

    Compared to past shutdowns, the Engineering Department Electrical Engineering (EN-EL) Group's activity volume will be multiplied by about four during LS1. The Group is experienced in handling such situations and will cope with this by transferring manpower from studies to worksite supervision and thanks to its subcontractors who know how to increase their manpower in such a manner as to maintain a good level of professionalism. EN-EL is substantially increasing its resources to cope with this workload. This increase in resources is, however, limited by the management capacity of EN-EL's core staff. As a consequence, not all of the requested activities will be possible and prioritization will be necessary. This paper details the upgrades and the consolidation to be carried out during LS1 and the measures taken by EN-EL to cope with this heavy workload.

    2007-08-21

    The White Phosphorus Burning Pits (WPP) Area of Concern (AOC) is a site of about 5.5 acres (2.2 ha) located in the J-Field Study Area, in the Edgewood Area of Aberdeen Proving Ground (APG), Maryland (Figure 1.1). Considerable information about the WPP exists as a result of efforts to characterize the hazards associated with J-Field. Contamination in the J-Field Study Area was first detected during an environmental survey of the APG Edgewood Area conducted in 1977 and 1978 (Nemeth et al. 1983) by the U.S. Army Toxic and Hazardous Materials Agency (USATHAMA; predecessor to the U.S. Army Environmental Center). As part of a subsequent USATHAMA environmental survey, 11 wells were installed and sampled at J-Field (three of them at the WPP) (Nemeth 1989). Contamination was also detected in 1983 during a munitions disposal survey conducted by Princeton Aqua Science (1984). The Princeton Aqua Science investigation involved installing and sampling nine wells (four at the WPP) and collecting and analyzing surficial and deep composite soil samples (including samples from the WPP area). In 1986, the U.S. Environmental Protection Agency (EPA) issued a Resource Conservation and Recovery Act (RCRA) Permit (MD3-21-002-1355) requiring a post-wide RCRA Facility Assessment (RFA) and a hydrogeologic assessment of J-Field. In 1987, the U.S. Geological Survey (USGS) began a two-phase hydrogeologic assessment in which data were collected to model groundwater flow at J-Field. Soil-gas investigations were conducted, several well clusters were installed (four at the WPP), a groundwater flow model was developed, and groundwater and surface water monitoring programs were established that continue today. The results of the USGS study were published by Hughes (1993).

  16. Solair heater program: solair applications study. Final report

    Energy Technology Data Exchange (ETDEWEB)

    1977-12-01

    General Electric has designed and tested a low-cost solar system using a vacuum tube solar air heater under ERDA Contract E(11-1)-2705. This contract extension has been provided to evaluate various applications of this solar collector. The evaluation identified attractive applications, evaluated corresponding control procedures, estimated system performance, compared economically insolation and insulation, and evaluated the repackaging of off-the-shelf equipment for improved cost effectiveness. The results of this study prompted General Electric's marketing group to do a detailed commercialization study of a residential domestic water heating system using the Solair concept which has been selected as the most attractive application. Other attractive applications are space/domestic water heating and a heat pump assisted solar system/domestic water heating where the heat pump and the solar system function in parallel. A prime advantage of heated air solar systems over liquid systems is cost and longer life which results in higher BTU's/dollar. Other air system advantages are no liquid leakage problems, no toxicity of freezing problems, and less complicated equipment. A hybrid solar system has been identified that can improve the market penetration of solar energy. This system would use the existing mass of the house for energy storage thereby reducing solar cost and complexity. Adequate performance can be obtained with house temperature swings comparable to those used in nighttime setback of the thermostat. Details of this system are provided.

    The Fortran 90 RIAPMTQ/IMPACT code package is a pair of linked beam-dynamics simulation codes that have been developed for end-to-end computer simulations of multiple-charge-state heavy-ion linacs for future exotic-beam facilities. These codes have multiple charge-state capability, and include space-charge forces. The simulations can extend from the low-energy beam-transport line after an ECR ion source to the end of the linac. The work has been performed by a collaboration including LANL, LBNL, ANL, and MSU. The code RIAPMTQ simulates the linac front-end beam dynamics including the LEBT, RFQ, and MEBT. The code IMPACT simulates the beam dynamics of the main superconducting linac. The codes have been benchmarked for rms beam properties against previously existing codes at ANL and MSU. The codes allow high-statistics runs on parallel supercomputing platforms, particularly at NERSC at LBNL, for studies of beam losses. The codes also run on desktop PC computers for low-statistics work. The code package is described in more detail in a recent publication [1] in the Proceedings of PAC07 (2007 US Particle Accelerator Conference). In this report we describe the main activities for the FY07 beam-loss studies project using this code package.

    Babcock and Wilcox entered into a contract with the Department of Energy (formerly the Energy Research and Development Administration) for the performance of a refueling outage availability study with the cooperation of Duke Power Company and Arkansas Power and Light Company. The objective was to improve plant availability through reduction of refueling outage time. The conclusions of the study were drawn from data gathered during the 1976 Oconee 3 and 1977 Arkansas Unit One refueling outages. The onsite effort was one of observation and data recording, which included time-lapsed photography and video tape. The collected data were then evaluated and analyzed for potential improvements and to identify in detail where resources were consumed. The overall result was a listing of (1) specific recommendations for implementing improvements in the facilities, equipment, tools, procedures, and techniques for the participating utilities; (2) generic recommendations of immediate benefit to other applicable utilities; and (3) recommendations for further work in the succeeding phases of the DOE program. The results indicate that, by incorporating the recommendations and taking credit for the time savings, an ideal refueling outage length of 21 to 22 days for the nuclear steam system (NSS) could be realized. Additional benefits would be a reduction in man-Rem exposure and manpower requirements.

  19. Energy conserving site design case study: Shenandoah, Georgia. Final report

    The case study examines the means by which energy conservation can be achieved at an aggregate community level by using proper planning and analytical techniques for a new town, Shenandoah, Georgia, located twenty-five miles southwest of Atlanta's Hartsfield International Airport. A potentially implementable energy conservation community plan is achieved by a study team examining the land use options, siting characteristics of each building type, alternate infrastructure plans, possible decentralized energy options, and central utility schemes to determine how community energy conservation can be achieved by use of pre-construction planning. The concept for the development of mixed land uses as a passively sited, energy conserving community is based on a plan (Level 1 Plan) that uses the natural site characteristics, maximizes on passive energy siting requirement, and allows flexibility for the changing needs of the developers. The Level 2 Plan is identical with Level 1 plan plus a series of decentraized systems that have been added to the residential units: the single-family detached, the apartments, and the townhouses. Level 3 Plan is similar to the Level 1 Plan except that higher density dwellings have been moved to areas adjacent to central site. The total energy savings for each plan relative to the conventional plan are indicated. (MCW)

    1999-03-01

    This project focuses on physiological and bioenergetic characteristics of two representative hyperthermophilic archaea: Thermococcus litoralis (T{sub opt} 88 C) and Pyrococcus furiosus (T{sub opt} 98 C). Both are obligately anaerobic heterotrophs which grow in the presence or absence of reducible sulfur compounds. T. litoralis was studied in relation to information previously developed for P. furiosus: effect of sulfur reduction on bioenergetics, preferred fermentation patterns, tungsten requirement, etc. A defined medium was developed for T. litoralis consisting of amino acids, vitamins and nucleotides. This serves as the basis for continuous culture studies probing metabolic response to media changes. P. furiosus and T. litoralis have also been found to produce a polysaccharide in the presence of maltose and yeast extract. The composition and chemical structure of this polysaccharide was investigated as well as the metabolic motivation for its production. A novel and, perhaps, primitive intracellular proteolytic complex (previously designated as protease S66) in P. furiosus was isolated and the gene encoding the subunit of the complex was cloned, sequenced and the protease expressed in active form in Eschericia coli. Among other issues, the role of this complex in protein turnover and stress response was examined in the context of this organism in addition to comparing it to other complexes in eubacterial and eukaryotic cells. Biochemical characteristics of the protease have been measured in addition to examining other proteolytic species in P. furiosus.

    As part of the U.S. Department of Energy's Low Wind Speed Turbine program, Global Energy Concepts LLC (GEC)1 has studied alternative composite materials for wind turbine blades in the multi-megawatt size range. This work in one of the Blade System Design Studies (BSDS) funded through Sandia National Laboratories. The BSDS program was conducted in two phases. In the Part I BSDS, GEC assessed candidate innovations in composite materials, manufacturing processes, and structural configurations. GEC also made recommendations for testing composite coupons, details, assemblies, and blade substructures to be carried out in the Part II study (BSDS-II). The BSDS-II contract period began in May 2003, and testing was initiated in June 2004. The current report summarizes the results from the BSDS-II test program. Composite materials evaluated include carbon fiber in both pre-impregnated and vacuum-assisted resin transfer molding (VARTM) forms. Initial thin-coupon static testing included a wide range of parameters, including variation in manufacturer, fiber tow size, fabric architecture, and resin type. A smaller set of these materials and process types was also evaluated in thin-coupon fatigue testing, and in ply-drop and ply-transition panels. The majority of materials used epoxy resin, with vinyl ester (VE) resin also used for selected cases. Late in the project, testing of unidirectional fiberglass was added to provide an updated baseline against which to evaluate the carbon material performance. Numerous unidirectional carbon fabrics were considered for evaluation with VARTM infusion. All but one fabric style considered suffered either from poor infusibility or waviness of fibers combined with poor compaction. The exception was a triaxial carbon-fiberglass fabric produced by SAERTEX. This fabric became the primary choice for infused articles throughout the test program. The generally positive results obtained in this program for the SAERTEX material have led to its

    The Quick-start Programme of the European Union Initiative for Growth identifies the hydrogen economy as one of the key areas for investment in the medium term (2004-2015). In this context the HyCOM (Hydrogen Communities) programme has been initiated. The main goal of this programme is the creation of a limited number of strategically sited stand-alone hydrogen communities producing hydrogen from various primary sources (mostly renewables) and using it for heat and electricity production and as fuel for vehicles. This report looks at the establishment of such hydrogen communities, analysing the main technical, economic, social, and environmental aspects as well as financial and regulatory barriers associated with the creation and operation of hydrogen communities. It also proposes a number of concepts for Hydrogen Communities and criteria with which a Hydrogen Community should be evaluated. The study is not in any way intended to be prescriptive. (ln)

    Saturns giant moon Titan has become one of the most fascinating bodies in the Solar System. Even though it is a billion miles from Earth, data from the Cassini mission reveals that Titan has a very diverse, Earth-like surface, with mountains, fluvial channels, lakes, evaporite basins, plains, dunes, and seas [Lopes 2010] (Figure 1). But unlike Earth, Titans surface likely is composed of organic chemistry products derived from complex atmospheric photochemistry [Lorenz 2008]. In addition, Titan has an active meteorological system with observed storms and precipitation-induced surface darkening suggesting a hydrocarbon cycle analogous to Earths water cycle [Turtle 2011].Titan is the richest laboratory in the solar system for studying prebiotic chemistry, which makes studying its chemistry from the surface and in the atmosphere one of the most important objectives in planetary science [Decadal 2011]. The diversity of surface features on Titan related to organic solids and liquids makes long-range mobility with surface access important [Decadal 2011]. This has not been possible to date, because mission concepts have had either no mobility (landers), no surface access (balloons and airplanes), or low maturity, high risk, and/or high development costs for this environment (e,g. large, self-sufficient, long-duration helicopters). Enabling in situ mobility could revolutionize Titan exploration, similarly to the way rovers revolutionized Mars exploration. Recent progress on several fronts has suggested that small-scale rotorcraft deployed as daughtercraft from a lander or balloon mothercraft may be an effective, affordable approach to expanding Titan surface access. This includes rapid progress on autonomous navigation capabilities of such aircraft for terrestrial applications and on miniaturization, driven by the consumer mobile electronics market, of high performance of sensors, processors, and other avionics components needed for such aircraft.

    During the first week of this effort, an Alpkem RFA-300 4-channel automated chemical analyzer was transferred to the basement of building 42 at TA-46 for the purpose of performing extraction studies. Initially, this instrumentation was applied to soil samples known to contain DNA. Using the SFA (Segmented Flow Analysis) technique, several fluidic systems were evaluated to perform on-line filtration of several varieties of soil obtained from Cheryl Kuske and Kaysie Banton (TA-43, Bldg. 1). Progress reports were issued monthly beginning May 15, 1996. Early in 1997 there was a shift from the conventional 2-phase system (aqueous + air) to a 3-phase system (oil + aqueous + air) to drastically reduce sample size and reagent consumption. Computer animation was recorded on videotape for presentations. The time remaining on the subcontract was devoted to setting up existing equipment to incorporate the 3rd phase (a special fluorocarbon oil obtained from DuPont).

    1980-07-01

    Under a contract with Argonne National Laboratory, VARTA Batterie AG. conducted a design and cost study of hydrogen-oxygen recombination devices (HORD) for use with utility load-leveling lead-acid cells. Design specifications for the devices, through extensive calculation of the heat-flow conditions of the unit, were developed. Catalyst and condenser surface areas were specified. The exact dimensions can, however, be adjusted to the cell dimension and the space available above the cell. Design specifications were also developed for additional components required to ensure proper function of the recombination device, including metal hydride compound decomposer, aerosol retainer, and gas storage component. Costs for HORD were estimated to range from $4 to $10/kWh cell capacity for the production of a large number of units (greater than or equal to 10,000 units). The cost is a function of cell size and positive grid design. 21 figures, 2 tables.

    The study focused on: (1) Development of reference design guidelines, evaluation criteria, and a methodology for evaluating and ranking candidate blanket concepts. (2) Compilation of the required data base and development of a uniform systems analysis for comparison. (3) Development of conceptual designs for the comparative evaluation. (4) Evaluation of leading concepts for engineering feasibility, economic performance, and safety. (5) Identification and prioritization of R and D requirements for the leading blanket concepts. Sixteen concepts (nine TMR and seven tokamak) which were identified as leading candidates in the early phases of the study, were evaluated in detail. The overall evaluation concluded that the following concepts should provide the focus for the blanket R and D program: (Breeder/Coolant/Structure), Lithium/Lithium/Vanadium Alloy, Li/sub 2/O/Helium/Ferritic Steel, LiPb Alloy/LiPb Alloy/Vanadium Alloy, and Lithium/Helium/Ferritic Steel. The primary R and D issues for the Li/Li/V concept are the development of an advanced structural alloy, resolution of MHD and corrosion problems, provision for an inert atmosphere (e.g., N/sub 2/) in the reactor building, and the development of non-water cooled near-plasma components, particularly for the tokamak. The main issues for the LiPb/LiPb/V concept are similar to the Li/Li/V blanket with the addition of resolving the tritium recovery issue. The R and D issues for Li/sub 2/O/He/FS concept include resolution of the tritium recovery/containment issue, achieving adequate tritium breeding and resolving other solid breeder issues such as swelling and fabrication concerns. Major concerns for the Li/He/FS concept are related to its rather poor economic performance. Improvement of its economic performance will be somewhat concept-dependent and will be more of a systems engineering issue.

And dispersal tests of the first, sec-ond and third layer mud tailings (200 mm in height for each layer) were carried out respectively to study the relationship between surface and stratified settlement, drainage discharge and time at dif-ferent locations from the central drain and the transaction between the settlement and drainage. The results show that the settlement tendency is the same for both surface and other layers, and the set-tlement is uniform. The final settlement was 110 mm or 13. 8% of the total height after the three lay-ers of red mud became stable. The drainage discharge is the largest when filling the first layer mud (6. 02% of the total discharge) , and it is reduced when filling the second and the third layer mud (5. 87% and 4. 22% of the total discharge, respectively).

    Los Alamos National Laboratory provided treatability study samples from four waste streams, designated Stream {number_sign}1, Stream {number_sign}3, Stream {number_sign}6, and Stream {number_sign}7. Stream {number_sign}1 consisted of one 55-gallon drum of personal protective equipment (PPE), rags, and neutralizing agent (bicarbonate) generated during the cleanup of a sodium dichromate solution spill. Stream {number_sign}3 was one 55-gallon drum of paper, rags, lab utensils, tools, and tape from the decontamination of a glovebox. The sample of Stream {number_sign}6 was packaged in three 30-gallon drums and a 100 ft{sup 3} wooden box. It consisted of plastic sheeting, PPE, and paper generated from the cleanup of mock explosive (barium nitrate) from depleted uranium parts. Stream {number_sign}7 was scrap metal (copper, stainless and carbon steel joined with silver solder) from the disassembly of gas manifolds. The objective of the treatability study is to determine: (1) whether the Perma-Fix stabilization/solidification process can treat the waste sample to meet Land Disposal Restrictions and the Waste Acceptance Criteria for LANL Technical Area 54, Area G, and (2) optimum loading and resulting weight and volume of finished waste form. The stabilized waste was mixed into grout that had been poured into a lined drum. After each original container of waste was processed, the liner was closed and a new liner was placed in the same drum on top of the previous closed liner. This allowed an overall reduction in waste volume but kept waste segregated to minimize the amount of rework in case analytical results indicated any batch did not meet treatment standards. Samples of treated waste from each waste stream were analyzed by Perma-Fix Analytical Services to get a preliminary approximation of TCLP metals. Splits of these samples were sent to American Environmental Network`s mixed waste analytical lab in Cary, NC for confirmation analysis. Results were all below applicable

    The goal of the Barrow Black Carbon Source and Impact (BBCSI) Study was to characterize the concentration and isotopic composition of carbonaceous atmospheric particulate matter (PM) at the Atmospheric Radiation Measurement site in Barrow, AK. The carbonaceous component was characterized via measurement of the organic and black carbon (OC and BC) components of the total PM. To facilitate complete characterization of the particulate matter, filter-based collections were used, including a medium volume PM2.5 sampler and a high volume PM10 sampler. Thirty-eight fine (PM2.5) and 49 coarse (PM10) particulate matter fractions were collected at weekly and bi-monthly intervals. The PM2.5 sampler operated with minimal maintenance during the 12 month campaign. The PM10 sampler used for the BBCSI used standard Tisch hi-vol motors which have a known lifetime of ~1 month under constant use; this necessitated monthly maintenance and it is suggested that the motors be upgraded to industrial blowers for future deployment in the Arctic. The BBCSI sampling campaign successfully collected and archived 87 ambient atmospheric particulate matter samples from Barrow, AK from July 2012 to June 2013. Preliminary analysis of the organic and black carbon concentrations has been completed. This campaign confirmed known trends of high BC lasting from the winter through to spring haze periods and low BC concentrations in the summer.

    1995-08-01

    This report explores feasibility of an anticipatory precrash restraint sensor. The foundation principle is the anticipation mechanism found at a primitive level of biological intelligence and originally formalized by the mathematical biologist Robert Rosen. A system based on formal anticipatory principles should significantly outperform conventional technologies. It offers the prospect of high payoff in prevention of death and injury. Sensors and processes are available to provide a good, fast, and inexpensive description of the present dynamical state of the vehicle to the embedded system model in the anticipation engine. The experimental part of this study found that inexpensive radar in a real-world setting does return useful data on target dynamics. The data produced by a radar system can be converted to target dynamical information by good, fast and inexpensive signal-processing techniques. Not only is the anticipatory sensor feasible, but further development under the sponsorship of the National Highway Traffic Safety Administration is necessary and desirable. There are a number of possible lines of follow-on investigation. The level of effort and expected benefits of various alternatives are discussed.

    In July 1981, the Academy of Natural Sciences of Philadelphia undertook a study to examine the numbers of finfish and blue crabs (Callinectes sapidus) entrained through the auxiliary cooling pumps at the Chalk Point Steam Electric Station (SES) operated by the Potomac Electric Power Company. Samples were collected by positioning a net attached to a hinged steel frame directly in the discharge of the auxiliary pumps. Concurrently, impingement rates of fish and blue crabs on the travelling screens were estimated by collecting the organisms washed into the troughs that lead to the discharge canal. A total of 6673 fish and blue crabs, representing 13 species, was collected in auxiliary pump samples at the Chalk Point generating station during July and August 1981. A total of 2154 fish and blue crabs representing seven species was collected in concurrent impingement samples. Blue crabs represented almost all of the total. The numbers of individuals entrained through auxiliary pumps showed a diel effect, with most individuals entrained at night.

  15. Studies of Transport Properties of Fractures: Final Report

    Stephen R. Brown

    2006-06-30

    We proposed to study several key factors controlling the character and evolution of fracture system permeability and transport processes. We suggest that due to surface roughness and the consequent channeling in single fractures and in fracture intersections, the tendency of a fracture system to plug up, remain permeable, or for permeability to increase due to chemical dissolution/precipitation conditions will depend strongly on the instantaneous flow channel geometry. This geometry will change as chemical interaction occurs, thus changing the permeability through time. To test this hypothesis and advance further understanding toward a predictive capability, we endeavored to physically model and analyze several configurations of flow and transport of inert and chemically active fluids through channels in single fractures and through fracture intersections. This was an integrated program utilizing quantitative observations of fractures and veins in drill core, quantitative and visual observations of flow and chemical dissolution and precipitation within replicas of real rough-walled fractures and fracture intersections, and numerical modeling via lattice Boltzmann methods.

    1982-05-01

    The objective of this study was to define and quantify cost reductions in the Martin Marietta Denver Aerospace Second Generation Heliostat resulting from design and cost optimization. These cost reductions were based on optimizing the heliostat performance vs. cost and engineering design, and reviewing the design specification in selected technological areas with a goal of removing nonrealistic requirements and eliminating or minimizing overdesign. Specific technological areas investigated were: (1) designing the heliostat for survival strength rather than stiffness and reducing the operational wind requirements as dictated by this design approach; (2) reducing the pointing accuracy and/or beam quality required for some fraction or all of the heliostat field; (3) modifying the operational temperature range; (4) relaxing the rate at which the heliostat must move in the slew mode; (5) using alternate beam safety strategies; (6) analyzing actual wind data for selected sites in the southwest United States vs. the heliostat design specification survival wind requirements; (7) estimating heliostat damage for winds in excess of the design specification over a 30 year period; (8) evaluating the impact of designing the heliostat for higher wind loads; and (9) investigating the applicability to heliostat design of the standard engineering practices for designing buildings.

    The objective of this study is to demonstrate the applicability of a radioisotope heated Mini-Brayton power system to the 1973 USAF/AEC requirements established for the SURVSATCOM Mission. The principal requiremenets of the power system, are: 400 We power level; maximum weight 205 lbs.; $1.2 to 2.0 million per unit cost; and 5y mission duration. A radioisotope heat source that meets the ACE Nuclear Safety Criteria is presented. The major aspects of the Reference Design MB-ERTG are summarized. The Reference Design, utilizes a flexible Brayton rotating unit (BRU), a /sup 244/Cm heat source with ceramic clad fuel cylinders and an aluminum radiator. The flexible BRU has a variable power output capability, from 400 We to 3000 We, and is an important factor in the formulation of a cost effective development plan. The system weight is 186 lb and unit cost, including the /sup 244/Cm fuel, acceptance testing and delivery is $748,000. The total development cost for the 5-yr program is estimated at $16.4M with an additional $6.5M required for /sup 244/Cm heat source development support, /sup 244/Cm fuel, heat source fabrication and capital equipment expenditures.

    The California Continental Borderland`s present configuration dates from about 4 to 5 X 10{sup 6} years Before Present (B.P.) and is the most recent of several configurations of the southern California margin that have evolved after the North America Plate over-rode the East Pacific Rise about 30 X 10{sup 6} years ago. The present morphology is a series of two to three northwest-southeast trending rows of depressions separated by banks and insular ridges. Two inner basins, Santa Monica and San Pedro, have been the site for the Department of Energy-funded California Basin Study (CaBS) Santa Monica and San Pedro Basins contain post-Miocene sediment thicknesses of about 2.5 and 1.5 km respectively. During the Holocene (past 10,000 years) about 10-12 m have accumulated. The sediment entered the basin by one or a combination of processes including particle infall (mainly as bioaggregates) from surface waters, from nepheloid plumes (surface, mid-depths and near-bottom), from turbidity currents, mass movements, and to a very minor degree direct precipitation. In Santa Monica Basin, during the last century, particle infall and nepheloid plume transport have been the most common processes. The former dominates in the central basin floor in water depths from 900 to 945 m. where a characteristic silt-clay with a typical mean diameter of about 0.006 mm, phi standard deviation.

    Histaminergic fibers are present in the molecular and granular layers of the cerebellum and have a high density in the vermis and flocullus. Evidence supports that the cerebellar histaminergic system is involved in memory consolidation. Our recent study showed that histamine injections facilitate the retention of an inhibitory avoidance task, which was abolished by pretreatment with an H2 receptor antagonist. In the present study, we investigated the effects of intracerebellar post training injections of H1 and H2 receptor antagonists as well as the selective H2 receptor agonist on fear memory consolidation. The cerebellar vermi of male mice were implanted with guide cannulae, and after three days of recovery, the inhibitory avoidance test was performed. Immediately after a training session, animals received a microinjection of the following histaminergic drugs: experiment 1, saline or chlorpheniramine (0.016, 0.052 or 0.16 nmol); experiment 2, saline or ranitidine (0.57, 2.85 or 5.07 nmol); and experiment 3, saline or dimaprit (1, 2 or 4 nmol). Twenty-four hours later, a retention test was performed. The data were analyzed using one-way analysis of variance (ANOVA) and Duncan's tests. Animals microinjected with chlorpheniramine did not show any behavioral effects at the doses that we used. Intra-cerebellar injection of the H2 receptor antagonist ranitidine inhibited, while the selective H2 receptor agonist dimaprit facilitated, memory consolidation, suggesting that H2 receptors mediate memory consolidation in the inhibitory avoidance task in mice.

    This report synthesizes the results of volcanism studies conducted by scientists at the Los Alamos National Laboratory and collaborating institutions on behalf of the Department of Energy's Yucca Mountain Project. An assessment of the risk of future volcanic activity is one of many site characterization studies that must be completed to evaluate the Yucca Mountain site for potential long-term storage of high-level radioactive waste. The presence of several basaltic volcanic centers in the Yucca Mountain region of Pliocene and Quaternary age indicates that there is a finite risk of a future volcanic event occurring during the 10,000-year isolation period of a potential repository. Chapter 1 introduces the volcanism issue for the Yucca Mountain site and provides the reader with an overview of the organization, content, and significant conclusions of this report. The risk of future basaltic volcanism is the primary topic of concern including both events that intersect a potential repository and events that occur near or within the waste isolation system of a repository. Future volcanic events cannot be predicted with certainty but instead are estimated using formal methods of probabilistic volcanic hazard assessment (PVHA). Chapter 2 describes the volcanic history of the Yucca Mountain region (YMR) and emphasizes the Pliocene and Quaternary volcanic record, the interval of primary concern for volcanic risk assessment. The distribution, eruptive history, and geochronology of Plio-Quaternary basalt centers are described by individual center emphasizing the younger postcaldera basalt (<5 Ma). The Lathrop Wells volcanic center is described in detail because it is the youngest basalt center in the YMR. The age of the Lathrop Wells center is now confidently determined to be about 75 thousand years old.

    The goal of the Barrow Black Carbon Source and Impact campaign was to characterize the concentration and isotopic composition of carbonaceous atmospheric particulate matter (PM) at the Atmospheric Radiation Measurement (ARM) Climate Research Facility site in Barrow, Alaska. The carbonaceous component was characterized by measuring the organic and black carbon (OC and BC) components of the total PM. To facilitate complete characterization of the PM, filter-based collections were used, including a medium volume PM2.5 sampler and a high volume PM10 sampler. Thirty-eight fine PM fractions (PM2.5) and 49 coarse (PM10) PM fractions were collected at weekly and bi-monthly intervals. The PM2.5 sampler operated with minimal maintenance during the 12 month campaign. The PM10 sampler used for the Barrow Black Carbon Source and Impact (BBCSI) study used standard Tisch “hi-vol” motors that have a known lifetime of approximately 1 month under constant use; this necessitated monthly maintenance, and it is suggested that, for future deployment in the Arctic, the motors be upgraded to industrial blowers. The BBCSI sampling campaign successfully collected and archived 87 ambient atmospheric PM samples from Barrow, Alaska, from July 2012 to June 2013. Preliminary analysis of the OC and BC concentrations has been completed. This campaign confirmed known trends of high BC lasting from the winter through to spring haze periods and low BC concentrations in the summer. However, the annual OC concentrations had a very different seasonal pattern with the highest concentrations during the summer, lowest concentrations during the fall, and increased concentrations during the winter and spring (Figure 1).

  4. System consolidation of memory during sleep.

    Born, Jan; Wilhelm, Ines

    2012-03-01

    Over the past two decades, research has accumulated compelling evidence that sleep supports the formation of long-term memory. The standard two-stage memory model that has been originally elaborated for declarative memory assumes that new memories are transiently encoded into a temporary store (represented by the hippocampus in the declarative memory system) before they are gradually transferred into a long-term store (mainly represented by the neocortex), or are forgotten. Based on this model, we propose that sleep, as an offline mode of brain processing, serves the 'active system consolidation' of memory, i.e. the process in which newly encoded memory representations become redistributed to other neuron networks serving as long-term store. System consolidation takes place during slow-wave sleep (SWS) rather than rapid eye movement (REM) sleep. The concept of active system consolidation during sleep implicates that (a) memories are reactivated during sleep to be consolidated, (b) the consolidation process during sleep is selective inasmuch as it does not enhance every memory, and (c) memories, when transferred to the long-term store undergo qualitative changes. Experimental evidence for these three central implications is provided: It has been shown that reactivation of memories during SWS plays a causal role for consolidation, that sleep and specifically SWS consolidates preferentially memories with relevance for future plans, and that sleep produces qualitative changes in memory representations such that the extraction of explicit and conscious knowledge from implicitly learned materials is facilitated.

  5. Consolidation of nanometer-sized aluminum single crystals: Microstructure and defects evolutions

    2014-04-01

    Deriving bulk materials with ultra-high mechanical strength from nanometer-sized single metalic crystals depends on the consolidation procedure. We present an accurate molecular dynamics study to quantify microstructure responses to consolidation. Aluminum single crystals with an average size up to 10.7 nm were hydrostatically compressed at temperatures up to 900 K and pressures up to 5 GPa. The consolidated material developed an average grain size that grew exponentially with the consolidation temperature, with a growth rate dependent on the starting average grain size and the consolidation pressure. The evolution of the microstructure was accompanied by a significant reduction in the concentration of defects. The ratio of vacancies to dislocation cores decreased with the average grain size and then increased after reaching a critical average grain size. The deformation mechanisms of poly-crystalline metals can be better understood in the light of the current findings. © 2013 Elsevier B.V. All rights reserved.

    Full Text Available Preparing consolidated financial statements has been a common practice for groups of companies around the world for a relatively long time, going back one century in the USA and tens of years in different European countries.A far-reaching issue regarding consolidation accounting policy is the concept of control, as it holds a crucial role in determining the basis of consolidation and the applicable method of consolidation and subsequently in influencing the content of the group financial statements. We focus in our article on the concept of exclusive control as it is approached by the relevant International, American and European standards, casting light also on possible future developments of this concept. The objective of our study is to acknowledge the differences and similarities between the approaches to the control concept, closing with the presentation of the influences of these approaches on the basis of consolidation.

  10. The consolidation of implicit sequence memory in obstructive sleep apnea.

    Directory of Open Access Journals (Sweden)

    Eszter Csabi

    Full Text Available Obstructive Sleep Apnea (OSA Syndrome is a relatively frequent sleep disorder characterized by disrupted sleep patterns. It is a well-established fact that sleep has beneficial effect on memory consolidation by enhancing neural plasticity. Implicit sequence learning is a prominent component of skill learning. However, the formation and consolidation of this fundamental learning mechanism remains poorly understood in OSA. In the present study we examined the consolidation of different aspects of implicit sequence learning in patients with OSA. We used the Alternating Serial Reaction Time task to measure general skill learning and sequence-specific learning. There were two sessions: a learning phase and a testing phase, separated by a 10-hour offline period with sleep. Our data showed differences in offline changes of general skill learning between the OSA and control group. The control group demonstrated offline improvement from evening to morning, while the OSA group did not. In contrast, we did not observe differences between the groups in offline changes in sequence-specific learning. Our findings suggest that disrupted sleep in OSA differently affects neural circuits involved in the consolidation of sequence learning.

  11. How aging affects sleep-dependent memory consolidation?

    Full Text Available Sleep plays multiple functions among which energy conservation or recuperative processes. Besides, growing evidence indicate that sleep plays also a major role in memory consolidation, a process by which recently acquired and labile memory traces are progressively strengthened into more permanent and/or enhanced forms. Indeed, memories are not stored as they were initially encoded but rather undergo a gradual reorganization process, which is favoured by the neurochemical environment and the electrophysiological activity observed during sleep. Two putative, probably not exclusive, models (hippocampo-neocortical dialogue and synaptic homeostasis hypothesis have been proposed to explain the beneficial effect of sleep on memory processes. It is worth noting that all data gathered until now emerged from studies conducted in young subjects. The investigation of the relationships between sleep and memory in older adults has sparked off little interest until recently. Though, aging is characterized by memory impairment, changes in sleep architecture, as well as brain and neurochemical alterations. All these elements suggest that sleep-dependent memory consolidation may be impaired or occurs differently in older adults.Here, we give an overview of the mechanisms governing sleep-dependent memory consolidation, and the crucial points of this complex process that may dysfunction and result in impaired memory consolidation in aging.

  12. Alternate Energy Sources for Thermalplastic Binding Agent Consolidation

    Energy Technology Data Exchange (ETDEWEB)

    Frame, B.J.

    1999-01-01

    A study was conducted to investigate microwave and electron beam technologies as alternate energy sources to consolidate fiber coated with a thermoplastic binding agent into preforms for composite molding applications. Bench experiments showed that both microwave and electron beam energy can produce heat sufficient to melt and consolidate a thermoplastic binding agent applied to fiberglass mat, and several two- and three-dimensional fiberglass preforms were produced with each method. In both cases, it is postulated that the heating was accomplished by the effective interaction of the microwave or electron beam energy with the combination of the mat preform and the tooling used to shape the preform. Both methods contrast with conventional thermal energy applied via infrared heaters or from a heated tool in which the heat to melt the thermoplastic binding agent must diffuse over time from the outer surface of the preform toward its center under a thermal gradient. For these reasons, the microwave and electron beam energy techniques have the potential to rapidly consolidate thick fiber preforms more efficiently than the thermal process. With further development, both technologies have the potential to make preform production more cost effective by decreasing cycle time in the preform tool, reducing energy costs, and by enabling the use of less expensive tooling materials. Descriptions of the microwave and electron beam consolidation experiments and a summary of the results are presented in this report.

  13. RLV Hopper: consolidated system concept

    The Hopper, a concept for a reusable launch system was developed and found attractive in the frame of FESTIP, ESA's Future European Space Transportation Initiation Programme. Later, in the national German ASTRA programme this concept was adapted to newly emerged requirement and subjected to a detailed design loop. Taking off horizontally and staging at high sub-orbital velocity, the Hopper needs a rail-guided launch sled, downrange landing, re-transportation back to the launch site, and one, but only one upper stage. Horizontal take-off is used to improve safety and to reduce thrust requirement, and number, mass, and cost of main engines, and also problems with vehicle centering. Transporting of the cargo (e.g. payload and expendable upper stage) in the RLV results in only one aerodynamically affected flight configuration. Staging at high sub-orbital velocity above the sensible atmosphere enables the use of only one standardised upper stage for all missions. Using a cryogenic upper stage the Hopper system is nearly optimally staged for the dimensioning GTO mission. The paper describes the consolidated unmanned RLV concept and highlights areas of special interest, evolution potential, and further steps. (Author)

    Farmland consolidation is the act of regulating, improving, and comprehensively renovating the structure, quality, and layout of field, water, road, forestry, and village in the countryside in a certain area by means of administration, economy, law, and engineering techniques according to the goal and usage defined by land use planning, so as to improve farmland use rate and its output rate, to increase farmland area, and to achieve better productive, living, and ecological environment. Recently, farmland consolidation has been carried out all over the country, especially in its economy-developed regions. But, unscientific planning and unsuitable farmland consolidation engineering have negative effects on field ecological system. In this paper, based on the technology of GIS and RS, the basic theories and methods of landscape ecology and a compositive grading method were applied to analysis the dynamics of farmland landscape fragmentation in Tongxiang county. The results showed that the farmland landscape fragmentation in this county was strongly affected by consolidation. More attention should be paid to the protection of farmland landscape during consolidation, and to avoid or decrease the negative effects resulted from unscientific planning and unsuitable farmland consolidation engineering.

Recognizing that positive type of political consolidation of society today admits democratic, despite existence of other types - nationalist, radical, religious and fundamentalist, the author carries out the analysis of its structural components, in relation to their reflectionand refraction in modern Russian sense of justice. The methodology includes logiko-legal, system and structural, concrete and sociological, and other methods of scientific sociological research. Results: By results of the analysis the conclusion of that modern Russian society seeks to be consolidated on mobilization type is drawn, round the specific personality, unconditionally supporting the bright political acts and actions embodying separate moods and expectations of masses. For the rest, from positions of sense of justice, the base of public consolidation remains very weak, therefore she hardly achievable. Accurately understanding it, the Russian power successfully substitutes public consolidation for consolidation of political establishment.

    A 78-year-old woman was admitted to our hospital because of dyspnea. A chest radiograph and a computed tomogram on admission showed air-space consolidation in the left upper lung field, and so pneumonia was diagnosed. Although antibiotics were administered, the air-space consolidation did not improve. A transbronchial lung biopsy was performed, yielding a pathologic diagnosis of poorly differentiated lung adenocarcinoma. Despite combination chemotherapy with docetaxel and UFT, the air-space consolidation expanded, and the patient finally died of respiratory failure 3 months after diagnosis. Autopsy revealed air-space consolidation due to poorly differentiated lung adenocarcinoma, with large atypical cells diffusely floating in the alveolar spaces. It has been recognized that bronchiolo-alveolar carcinoma and well-differentiated lung adenocarcinoma present with air-space consolidation, reflecting the cancer cells lining the alveolar walls. However, in this case, the air-space consolidation was due to cancer cells diffusely floating in the alveolar spaces in aerogenic metastasis. It was considered that this is a rare case, which presented with a very interesting development pattern.

    2006-02-01

    Animal studies indicate that adrenal glucocorticoids enhance memory consolidation while impairing memory retrieval. In humans, beneficial effects on consolidation have been observed infrequently. In the current double-blind study, subjects (N = 29) received placebo or cortisol (30 mg) 10 min before viewing emotionally arousing or neutral pictures. Cortisol treatment had no effects on immediate recall. In the 24-hr delayed recall condition, cortisol led to an enhanced emotional memory facilitation because of decreased neutral and increased emotional memory recall. No effects of cortisol treatment were observed for recognition memory or mood. Results support the notion that glucocorticoids specifically enhance the consolidation of emotional material.

  1. Behavioral and Neural Analysis of GABA in the Acquisition, Consolidation, Reconsolidation, and Extinction of Fear Memory

    2010-01-01

    The current review systematically documents the role of γ-amino-butyric acid (GABA) in different aspects of fear memory—acquisition and consolidation, reconsolidation, and extinction, and attempts to resolve apparent contradictions in the data in order to identify the function of GABAA receptors in fear memory. First, numerous studies have shown that pre- and post-training administration of drugs that facilitate GABAergic transmission disrupt the initial formation of fear memories, indicating a role for GABAA receptors, possibly within the amygdala and hippocampus, in the acquisition and consolidation of fear memories. Similarly, recent evidence indicates that these drugs are also detrimental to the restorage of fear memories after their reactivation. This suggests a role for GABAA receptors in the reconsolidation of fear memories, although the precise neural circuits are yet to be identified. Finally, research regarding the role of GABA in extinction has shown that GABAergic transmission is also disruptive to the formation of newly acquired extinction memories. We argue that contradictions to these patterns are the result of variations in (a) the location of drug infusion, (b) the dosage of the drug and/or (c) the time point of drug administration. The question of whether these GABA-induced memory deficits reflect deficits in retrieval is discussed. Overall, the evidence implies that the processes mediating memory stability consequent to initial fear learning, memory reactivation, and extinction training are dependent on a common mechanism of reduced GABAergic neurotransmission.

    In the starch consolidation (SC) process, a water-based slurry containing powder, starch, dispersant and thickener is used to fabricate near net-shape green bodies that are de-binded and further consolidated by sintering. In this study, gas atomized M3/2 as well as high and low carbon V-rich M4 type high speed steel powder (<150 {mu}m) are considered. Both material types undergo high volumetric shrinkage during super-solidus liquid phase sintering enabling them to reach near full density. The analyses and the review cover different process aspects like: recipe optimisation, post-gelatinization drying, de-binding and sintering. A SC recipe consisting of 58 vol.% powder, 3 vol.% starch, 1 vol.% dispersant and a thickener solution resulted in a density of >98% than what is theoretically stated after sintering. It is found that the success of the post-gelatinization drying procedure depends on the smoothness of mould material and controlling powder oxidation. The best combination was freeze drying the slurry in a silicon rubber mould. For V-rich alloys a total or partial control of eutectic carbides in the final microstructure could be realized for vacuum and nitrogen sintering atmospheres, respectively.

    It has been suggested that sleep selectively enhances memories with future relevance. Given that sleep's benefits can vary by item within a learning context, the present study investigated whether the amount of sleep-dependent consolidation may vary across items based on the value of the to-be-learned material. For this purpose, we used a value-based learning paradigm in which participants studied words paired with point values. There were two groups; participants either studied the words in the evening and were tested after a 12 hr interval containing a full night of sleep, or studied the words in the morning and were tested after 12 hr of continuous daytime wake. Free recall (F(1,36) = 19.35, pvalue for sleep and wake groups (p = .74). Thus, while encoding may vary with the value of the to-be-learned item, sleep-dependent consolidation does not.

    The evaluation of change in ecosystem service value arising from land consolidation planning is an important aspect of environmental impact assessment of land consolidation. By estimating the change in ecosystem service value before and after the implementation of land consolidation planning, it is able to quantitatively describe the change in ecosystem service value arising from land consolidation planning, so as to provide a quantitative basis for the environmental impact assessment of land consolidation. Taking the case of Anhui Province, the authors developed the equivalency factor table of ecosystem service value, to determine the economic value of single equivalency factor of ecological service value in the study area, calculate per unit area of ecological service value of land ecosystem in the study area, and research the change in ecosystem service value before and after the implementation of land consolidation planning in Anhui Province. The results show that after the implementation of a new round of land consolidation planning in Anhui Province, the total ecosystem service value may decrease to some extent, the farmland ecosystem service value substantially increases, while water body ecosystem service value greatly decreases.

According to the analysis of the correlation theory of land consolidation, using the results of agriculture land productivity calculation, and land production potential to that sort of natural potential, a comprehensive evaluation index system was established by the 9 indexes relating to economy, society and infrastructure to calculate the natural potential of land consolidation, and the modified coefficient of realistic potential was analyzed using the Analytic Hierarchy Process (AHP) method in the index system. Finally, it was implemented in Suning County. The results showed that natural potential of farmland consolidation in Suning County is 170 588.99 tons; and the modified coefficient in each village and town varied from 0. 142 3~0. 651 5; realistic potential of farmland consolidation in Suning County is 64 329.25 tons based in the modification, mainly concentrating in the town of Liangcun and Wanli town.

    Post-learning stress has been reported to enhance memory consolidation in humans. This effect was observed in studies using physical stressors or an anticipatory speech task. In the present study 58 participants (28 females and 30 males) were exposed to a psychosocial stressor (Trier Social Stress Test) or a control condition following the presentation of neutral and emotionally arousing positive and negative pictures, which were accompanied by a brief narrative. The stressor induced a significant neuroendocrine stress response in men and women. In a 24h delayed free recall test the stress group showed an enhanced memory for neutral but not for emotionally arousing positive and negative items. Additionally, a significant correlation between the cortisol stress response and memory for neutral items was evident. Thus, in contrast to previous studies, post-learning stress primarily enhanced consolidation of neutral material. Several theoretical and methodological explanations for the observed effects are discussed.

    Additional results confirm that during most of the consolidation of polycrystalline salt in brine, the previously proposed rate expression applies. The final consolidation, however, proceeds at a lower rate than predicted. The presence of clay hastens the consolidation process but does not greatly affect the previously observed relationship between permeability and void fraction. Studies of the migration of brine within polycrystalline salt specimens under stress indicate that the principal effect is the exclusion of brine as a result of consolidation, a process that evidently can proceed to completion. No clear effect of a temperature gradient could be identified. A previously reported linear increase with time of the reciprocal permeability of salt-crystal interfaces to brine was confirmed, though the rate of increase appears more nearly proportional to the product of sigma ..delta..P rather than sigma ..delta..P/sup 2/ (sigma is the uniaxial stress normal to the interface and ..delta..P is the hydraulic pressure drop). The new results suggest that a limiting permeability may be reached. A model for the permeability of salt-crystal interfaces to brine is developed that is reasonably consistent with the present results and may be used to predict the permeability of bedded salt. More measurements are needed, however, to choose between two limiting forms of the model.

    Sleep-related memory consolidation has received increasing attention in recent years. Because previous research has focused on healthy young adults, only very few studies have been conducted in patients with psychiatric disorders so far. The investigation of sleep-related memory consolidation in depression offers a wide range of future research opportunities and can therefore be regarded as an emerging field of research. This article gives a short overview of current knowledge of sleep-related memory consolidation in healthy young adults and builds a bridge to psychiatry and depression, where further research is urgently needed.

    High-resolution CT showed areas of airspace consolidation with a twisted appearance of the airways, along with areas of peribronchial ground-glass attenuation and traction bronchiectasis, in five patients with interstitial pneumonia. These areas of airspace consolidation were termed "twisted consolidation" (TwC). The five patients included two patients receiving treatment for rheumatoid arthritis (RA), one patient with newly diagnosed RA, and one patient who subsequently showed RA. Three patients showed improvement after steroid administration. An association of TwC with RA is suspected, but further studies are necessary.

    2013-01-01

    In reduced coordinates, a one-dimensional finite strain consolidation equation for saturated soils is derived with threshold gradient. The new equation shows that threshold gradient and variation of permeability coefficient with void ratio should be considered. Using the two empirical relations proposed by Mesri, a new governing equation is obtained. Then three examples are analyzed by applying the partial differential finite element software FlexPDE. The results show that excess pore water pressure slightly increases at the beginning of consolidation progress and then dissipates. This phenomenon is similar to the Mandel-Cryer effect. It will be more significant if threshold gradient is greater or location of soil is deeper. Even though the maximum excess pore water pressure increases when threshold gradient increases, the increment is very small. It is too difficult for us to observe the tiny increments in laboratory and practical engineerings. Therefore, there is no need to consider threshold gradient in vast majority of actual projects. In other words, classical Carey's law is applicable. This research shows that it is very important to consider threshold gradient, geometric nonlinearity and material nonlinearity in studying the Mandel-Cryer effect so as to further understand the consolidation properties of saturated soils.%在固相物质坐标下推导出了考虑起始比降的饱和土体一维大应变固结控制方程.从新方程可以看出,要综合考虑土体固结过程中的渗流非线性,要同时考虑起始比降和渗透系数随孔隙比的变化.采用Mesri提出的两个经验关系式进一步推导出了新的控制方程.借助偏微分有限元软件FlexPDE对3个算例进行了分析.分析结果表明,土体固结开始阶段超静孔压先略微增大,然后减小,类似于Mandel-Cryer效应.起始比降越大,土层越深,该现象越显著.虽然超静孔压最大值随起始比降的增大而增大,但增量很小.如此微小的

  19. On The Thermal Consolidation Of Boom Clay

    Delage, Pierre; Cui, Yu-Jun

    2012-01-01

    When a mass of saturated clay is heated, as in the case of host soils surrounding nuclear waste disposals at great depth, the thermal expansion of the constituents generates excess pore pressures. The mass of clay is submitted to gradients of pore pressure and temperature, to hydraulic and thermal flows, and to changes in its mechanical properties. In this work, some of these aspects were experimentally studied in the case of Boom clay, so as to help predicting the response of the soil, in relation with investigations made in the Belgian underground laboratory at Mol. Results of slow heating tests with careful volume change measurements showed that a reasonable prediction of the thermal expansion of the clay-water system was obtained by using the thermal properties of free water. In spite of the density of Boom clay, no significant effect of water adsorption was observed. The thermal consolidation of Boom clay was studied through fast heating tests. A simple analysis shows that the hydraulic and thermal trans...

    The Antiproton Decelerator (AD), which started up for physics in 2000 and today supplies low-energy antiprotons to the ATRAP, ALPHA, ASACUSA and ACE experiments is based on the ACOL machine from which it still retains most of the components. ACOL construction was completed in 1986 at a total cost of approximately 80 MCHF (excluding infrastructure) which today would correspond to a value of around 160 MCHF. During recent years, a reduction of maintenance and modernisation has been unavoidable due to budgetary restraints. In order to identify the resources needed for continued AD operation beyond 2010 with a reasonably low risk of failures and to avoid increasing maintenance and repair costs, a study has been conducted involving groups from the AB, AT and TS departments. Analysis of breakdown risks, identification of items and costs for consolidation has been done as well as a risk score classification. To be noted is the relatively modest cost of the proposed items in view of the value of the facility and in c...

    Mancino, D M

    1997-01-01

    The changing dynamics of healthcare service delivery is forcing many physicians to consider selling their practices to hospitals or health plans or consolidating them with other practices. Besides being subject to the corporate and tax requirements that apply to the sale of any business, the sale of physician practices is also subject to Federal fraud and abuse and self-referral laws. Several sale strategies are available to physicians who desire to sell or consolidate their practices, including asset sales, stock sales, forward mergers, drop down consolidations, spinoffs, and statutory mergers. Each strategy has advantages and disadvantages, but whichever strategy is chosen, both sellers and buyers must ensure that tax issues are addressed and that the transaction complies with the requirements of Federal anti-kickback and self-referral laws.

    Full Text Available In contemporary market conditions facing continuous debt crisis, the notion of fiscal consolidation is one of potential solutions for solving the main economic issues in any country. As regards fiscal consolidation, it necessary to point out to the importance of developing strategies aimed at minimizing deficit and debt level. Serbia is among those countries in which irrational spending is widely present with unfavourable tendency regarding the aspect of production and consumption. Over the past 25 years, Serbia has spent much more than it has produced, which has led to large budget deficits and debt level. The aim is to point out to the concept of fiscal consolidation and its implementation in Serbia, while the subject of this paper is to present the package of measures and strategies defined by the government of the Republic of Serbia and the Fiscal Council Program.

    Description of the mechanisms controlling the generation and movement of low-quality waters that are acidic or neutral in pH and contain high concentrations of dissolved constituents in their tailings impoundments at the Waite Amulet copper-zinc mine in Quebec, Heath Steele zinc-lead mine in New Brunswick, and the former Delnite gold mine in Ontario. The report also describes supplementary field studies conducted at three inactive nickel mine tailings impoundments in Sudbury basin, and research initiated at the Kidd Creek complex massive sulfide mine tailings impoundment near Timmins, Ontario. The results of these studies are compared to those obtained from the other three impoundments to assess the effects of variable mineralogy and hydrogeological conditions on the resulting pore-water chemistry and potential environmental effects of the tailings impoundment. Finally, the report describes the application of the data collected from the field sites to assess passive geochemical approaches to the abatement of low-quality mine drainage waters, including an assessment of the role of hardpan layers in controlling the movement of pore gases in tailings impoundments and the potential for the enhancement of the formation of hardpan layers.

  9. Consolidation power of extrinsic rewards: reward cues enhance long-term memory for irrelevant past events.

    Science.gov (United States)

    Murayama, Kou; Kitagami, Shinji

    2014-02-01

    Recent research suggests that extrinsic rewards promote memory consolidation through dopaminergic modulation processes. However, no conclusive behavioral evidence exists given that the influence of extrinsic reward on attention and motivation during encoding and consolidation processes are inherently confounded. The present study provides behavioral evidence that extrinsic rewards (i.e., monetary incentives) enhance human memory consolidation independently of attention and motivation. Participants saw neutral pictures, followed by a reward or control cue in an unrelated context. Our results (and a direct replication study) demonstrated that the reward cue predicted a retrograde enhancement of memory for the preceding neutral pictures. This retrograde effect was observed only after a delay, not immediately upon testing. An additional experiment showed that emotional arousal or unconscious resource mobilization cannot explain the retrograde enhancement effect. These results provide support for the notion that the dopaminergic memory consolidation effect can result from extrinsic reward.

  10. The consolidation of rafted sea ice

    Science.gov (United States)

    Bailey, E.; Feltham, D.; Sammonds, P.

    2009-04-01

    Rafting is an important process in the deformation of sea ice that occurs when two ice sheets collide. This process is particularly common in the North Caspian Sea, where ice floes override one another multiple times to produce thick sea ice features. To date, rafting has received little attention in the literature perhaps because in most regions pressure ridges produce the greatest loads on offshore structures. In the North Caspian Sea the shallow waters constrain the size to which pressure ridges can grow and the low salinity seems to favor rafting over ridging. Therefore it is likely that multiply-rafted sea ice may be the governing design feature for ice loads in the Caspian Sea. Here we present a one-dimensional, thermal-consolidation model for rafted sea ice. This is of interest because the degree of consolidation will affect the strength of a rafted structure, and therefore may be of value for modeling rafted ice loads. Results show that the thickness of the liquid layers reduces asymptotically with time, such that there always remains a thin liquid layer. We propose that when the liquid layer is equal to the surface roughness the adjacent layers can be considered consolidated. Using parameters specific to the North Caspian Sea, calculations show that it took 1hr, 14mins for the ice sheets to consolidate. To test the accuracy of the model concurrent experiments were carried out in the HSVA ice basin. During an experiment, equally sized portions of level ice were manually piled on top of one another to produce a rafted section. The rate of consolidation or bonding of the layers was then monitored by coring and using thermistors that were frozen into the level ice prior to rafting. Once consolidated, strength tests were carried out on the rafted ice and compared with those of level ice.

  11. Mental rotation: effects of gender, training and sleep consolidation.

    Directory of Open Access Journals (Sweden)

    Ursula Debarnot

    Full Text Available A wide range of experimental studies have provided evidence that a night of sleep contributes to memory consolidation. Mental rotation (MR skill is characterized by fundamental aspect of both cognitive and motor abilities which can be improved within practice sessions, but little is known about the effect of consolidation after MR practice. In the present study, we investigated the effect of MR training and the following corresponding day- and sleep-related time consolidations in taking into account the well-established gender difference in MR. Forty participants (20 women practiced a computerized version of the Vandenberg and Kuse MR task. Performance was evaluated before MR training, as well as prior to, and after a night of sleep or a similar daytime interval. Data showed that while men outperformed women during the pre-training test, brief MR practice was sufficient for women to achieve equivalent performance. Only participants subjected to a night of sleep were found to enhance MR performance during the retest, independently of gender. These results provide first evidence that a night of sleep facilitates MR performance compared with spending a similar daytime interval, regardless gender of the participants. Since MR is known to involve motor processes, the present data might contribute to schedule relevant mental practice interventions for fruitful applications in rehabilitation and motor learning processes.

  12. Variation of hydraulic gradient in nonlinear finite strain consolidation

    2014-01-01

    In the research field of ground water, hydraulic gradient is studied for decades. In the consolidation field, hydraulic gradient is yet to be investigated as an important hydraulic variable. So, the variation of hydraulic gradient in nonlinear finite strain consolidation was focused on in this work. Based on lab tests, the nonlinear compressibility and nonlinear permeability of Ningbo soft clay were obtained. Then, a strongly nonlinear governing equation was derived and it was solved with the finite element method. Afterwards, the numerical analysis was performed and it was verified with the existing experiment for Hong Kong marine clay. It can be found that the variation of hydraulic gradient is closely related to the magnitude of external load and the depth in soils. It is interesting that the absolute value of hydraulic gradient (AVHG) increases rapidly first and then decreases gradually after reaching the maximum at different depths of soils. Furthermore, the changing curves of AVHG can be roughly divided into five phases. This five-phase model can be employed to study the migration of pore water during consolidation.

    The Japan Collaborative Cohort Study for Evaluation of Cancer Risk (JACC Study) was established in the late 1980s to evaluate the risk impact of lifestyle factors and levels of serum components on human health. During the 20-year follow-up period, the results of the study have been published in almost 200 original articles in peer-reviewed English-language journals. However, continued follow-up of the study subjects became difficult because of the retirements of principal researchers, city mergers throughout Japan in the year 2000, and reduced funding. Thus, we decided to terminate the JACC Study follow-up at the end of 2009. As a final point of interest, we reviewed the population registry information of survivors. A total of 207 (0.19%) subjects were ineligible, leaving 110 585 eligible participants (46 395 men and 64 190 women). Moreover, errors in coding date of birth and sex were found in 356 (0.32%) and 59 (0.05%) cases, respectively, during routine follow-up and final review. Although such errors were unexpected, their impact is believed to be negligible because of the small numbers relative to the large total study population. Here, we describe the final cohort profile at the end of the JACC Study along with selected characteristics of the participants and their status at the final follow-up. Although follow-up of the JACC Study participants is finished, we will continue to analyze and publish study results.

  16. New insights in human memory interference and consolidation.

    2012-01-24

    Learning new facts and skills in succession can be frustrating because no sooner has new knowledge been acquired than its retention is being jeopardized by learning another set of skills or facts. Interference between memories has recently provided important new insights into the neural and psychological systems responsible for memory processing. For example, interference not only occurs between the same types of memories, but can also occur between different types of memories, which has important implications for our understanding of memory organization. Converging evidence has begun to reveal that the brain produces interference independently from other aspects of memory processing, which suggests that interference may have an important but previously overlooked function. A memory's initial susceptibility to interference and subsequent resistance to interference after its acquisition has revealed that memories continue to be processed 'off-line' during consolidation. Recent work has demonstrated that off-line processing is not limited to just the stabilization of a memory, which was once the defining characteristic of consolidation; instead, off-line processing can have a rich diversity of effects, from enhancing performance to making hidden rules explicit. Off-line processing also occurs after memory retrieval when memories are destabilized and then subsequently restabalized during reconsolidation. Studies are beginning to reveal the function of reconsolidation, its mechanistic relationship to consolidation and its potential as a therapeutic target for the modification of memories.

    Source monitoring refers to cognitive processes involved in making attributions about the origins of memories, knowledge, and beliefs. One particular type of source monitoring with ample practical significance is reality monitoring, i.e., the ability to discriminate between internally vs. externally generated memories. Abundant evidence indicates that exposure to acute stress enhances declarative memory consolidation. To date, no study has looked at whether exposure to acute stress during the consolidation phase may promote reality monitoring performance. The authors examined this by administering cold pressor stress (CPS) or a control procedure to participants (N = 80) after they had either performed or only imagined performing simple motor acts, and assessing reality monitoring 24 h later. When compared with the control condition, CPS significantly elevated salivary free cortisol concentrations and enhanced reality monitoring. Stress-induced cortisol responses, however, were found not to be related to improved reality monitoring performance. Our findings are consistent with the view that post-learning stress hormone-related activity may modulate source memory consolidation.

    The use of curable resin-coated proppants (RCPs) for controlling proppant flowback after hydraulic fracturing treatments and in screenless, fracpack completions is widespread. However,the cure kinetics of the RCP chosen for a particular application are generally ignored. This paper reviews the results of a study comparing the consolidation performance of RCPs with different cure kinetics under simulated treatment and downhole conditions. Techniques for determining RCPs cure kinetics are also described, including differential calorimetry (DSC), rock mechanical measurements, and scanning electron microscopy (SEM). Results of SEM analysis showed that in fast curing RCPs there was a decrease in the number of contact points between proppant grains, and a loss of consolidation strength when faster curing RCPs were exposed to fluids for various periods of time before onset of closures. The information helps to improve understanding the failure mechanisms of RCPs and provides guidelines for selecting the most appropriate RCP to be used in screenless completions where consolidations are expected to withstand production conditions of high flow rates and stress cycling. 8 refs., 15 figs.

    It is estimated that cohesive soils are present in about in about 80% of the Cuban territory. Most of these soils are pre consolidated as a result of the country's geo-environmental conditions. That's why it is important, in the Cuban context, to determine accurately the soil pre consolidation load, correct the oedometric curve and apply these concepts to settlement computation. In this paper, a study is presented to define how to estimate the pre consolidation pressure by using several methods. A database was created. It consisted of 102 pre consolidated soils, which are typical from the central region of Cuban. These soil we analyzed by several Cuban geotechnical research centers. (Author) 12 refs.

    To assess the outcomes of outpatient high dose cytosine arabinoside consolidation cycles in pediatric acute myeloid leukemia (AML) patients in comparison to inpatient treatment. We retrospectively analyzed 90 cycles of AML consolidation given to 30 patients between July 2003 and July 2007. Median age was 8 years (range 1.5-15) and 22/30 (73.3%) were males. Sixty-nine of 90 (76.7%) cycles were given on an ambulatory basis; readmission occurred in 25/69 (36.2%) and there was one death. The outpatient cycles in comparison to the inpatient cycles required significantly fewer invasive blood investigations (pconsolidation therapy is safe and feasible in children. It appears to result in less frequent invasive blood studies; shorter duration of febrile neutropenia and consequently less antimicrobial and antifungal usage as compared to inpatient consolidation cycles. To our knowledge, this report is the first of its kind looking specifically at outpatient consolidation chemotherapy in AML.

  1. Coupling of Thalamocortical Sleep Oscillations Are Important for Memory Consolidation in Humans.

    Directory of Open Access Journals (Sweden)

    Mohammad Niknazar

    Full Text Available Sleep, specifically non-rapid eye movement (NREM sleep, is thought to play a critical role in the consolidation of recent memories. Two main oscillatory activities observed during NREM, cortical slow oscillations (SO, 0.5-1.0 Hz and thalamic spindles (12-15 Hz, have been shown to independently correlate with memory improvement. Yet, it is not known how these thalamocortical events interact, or the significance of this interaction, during the consolidation process. Here, we found that systemic administration of the GABAergic drug (zolpidem increased both the phase-amplitude coupling between SO and spindles, and verbal memory improvement in humans. These results suggest that thalamic spindles that occur during transitions to the cortical SO Up state are optimal for memory consolidation. Our study predicts that the timely interactions between cortical and thalamic events during consolidation, contribute to memory improvement and is mediated by the level of inhibitory neurotransmission.

    It is often suggested that sleep-dependent consolidation of motor learning is impaired in older adults. The current study challenges this view and suggests that the degree of motor consolidation seen with sleep in older age groups depends on the kinematic demands of the task. We show that, when tested with a classic sequence learning task, requiring individuated finger movements, older adults did not show sleep-dependent consolidation. By contrast, when tested with an adapted sequence learning task, in which movements were performed with the whole hand, sleep-dependent motor improvement was observed in older adults. We suggest that age-related decline in fine motor dexterity may in part be responsible for the previously described deficit in sleep-dependent motor consolidation with aging.

    Colloids and Material Science are nowadays providing innovative and effective technological solutions in a wide range of applicative fields. In the last decade, nanomaterials have been specifically designed to ensure the long-term restoration and preservation of movable and immovable artworks. The main tasks to address by conservation scientists concern the cleaning, the deacidification and the consolidation of different kinds of artistic substrates. The aim of the present contribution is to provide an up-to-date overview on the synthesis and preparation of colloidal systems tailored to the consolidation and protection of wall paintings, plasters and stones, highlighting the most recent improvements. Two case studies, widely representative of typical consolidation problems, are presented, i.e. the preservation of wall paintings belonging to a Mesoamerican archeological site and the consolidation of two Italian Renaissance buildings.

    2003-07-01

    Mechanically alloyed aluminium, MA Al, powder particles are hard and covered by surface oxide layers. This gives problems in consolidation processing. Consolidation is often carried out by hot extrusion, as the main processing step. An alternative consolidation method consisting in a press-and-sinter process has been developed at the University of Seville. MA Al powder was prepared by attrition milling. To improve the sinterability of MA Al powder, small amounts of magnesium, ranging from 0.0 to 1.2 wt% Mg, were added after milling. The mixed powder was consolidated by cold pressing (1120 MPa) and vacuum sintering (650 C, 1 h). Different mechanical and structural studies have been carried out. It has been observed that the addition of magnesium improves the mechanical properties of sintered MA Al. This is attributed to the reducing action of Mg on the Al sesquioxide layer and to the formation of liquid phases during sintering. (orig.)

    Based on the modern comprehensive evaluation method, in accordance with the scientific, objective and systematic principles, we select four factors (economic, social, ecological and landscape benefits), to establish the evaluation indicator system of comprehensive benefits of rural land consolidation. Then using the theory of fuzzy mathematics (FUZZY) and fuzzy relationship synthesis theory, we establish the fuzzy evaluation model of comprehensive benefits of land consolidation; using analytic hierarchy process (AHP), we determine the weight of each indicator, and conduct fuzzy comprehensive evaluation from various levels. By the weighted average synthesis algorithm, we calculate the evaluation indicators and finally summarize the overall evaluation results for comprehensive evaluation. Taking the case of land consolidation project in Shangyao Town, Datong District, Huainan City in Anhui Province, we calculate the case data based on Matlab software, and the calculation results and evaluation level are consistent with the project acceptance results, verifying the feasibility of this evaluation method.

    Migrating pulmonary lesions in children are uncommon, and most are caused by eosinophilic lung disease and parasite, fungus, and tuberculosis infections. A 12-year-old boy was referred to our hospital because of an abnormal chest x-ray. Serial computed tomography scans performed over several months showed a migrating pulmonary consolidation in the left lung, although the patient remained asymptomatic. Finally, surgical biopsy was performed and follicular bronchiolitis was diagnosed. The consolidation disappeared 17 months later without treatment, and the patient has remained asymptomatic. Primary follicular bronchiolitis could be considered as one of the differential diagnosis in patients with pulmonary reticulo-nodular consolidation. It should also be noted that follicular bronchiolitis can migrate. Pediatr Pulmonol. 2017;52:E22-E25. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

    The study of Dalitz plots of heavy-meson decays to multi-hadron final states has received intensified interest by the possibility to gain access to precision investigations of CP violation. A thorough understanding of the hadronic final-state interactions is a prerequisite to achieve a highly sensitive, model-independent study of such Dalitz plots. We illustrate some of the theoretical tools, predominantly taken from dispersion theory, available for these and related purposes, and discuss the low-energy decays omega, phi --> 3pi in some more detail.

  9. Consolidation analysis of composite foundation with partially penetrated cement fly-ash gravel (CFG) piles under changing permeable boundary conditions

    2015-01-01

    Based on the double-layered foundation theory, the composite ground with partially penetrated cement fly-ash gravel (CFG) piles was regarded as a double-layered foundation including the surface reinforced area and the underlying untreated stratum. Due to the changing permeability property of CFG piles, the whole consolidation process of the composite ground with CFG piles was divided into two stages, i.e., the early stage (permeable CFG pile bodies) and the later stage (impermeable pile bodies). Then, the consolidation equation of the composite foundation with CFG piles was established by using the Terzaghi one-dimensional consolidation theory. Consequently, the unified formula to calculate the excess pore water pressure was derived with the specific solutions for the consolidation degree of composite ground, reinforced area and underlying stratum under instant load obtained respectively. Finally, combined with a numerical example, influencing rules by main factors (including the replacement ratem, the treatment depthh1, the permeability coefficientKs1,Kv2and compression modulusEs1,Es2 of reinforced area and underlying stratum) on the consolidation property of composite ground with CFG piles were discussed in detail. The result shows that the consolidation velocity of underlying stratum is slower than that of the reinforced area. However, the consolidation velocity of underlying stratum is slow at first then fast as a result of the transferring of effective stress to the underlying stratum during the dissipating process of excess pore water pressure.

  10. Analytical Analysis and Field Test Investigation of Consolidation for CCSG Pile Composite Foundation in Soft Clay

    2013-01-01

    Full Text Available Low-grade concrete-cored sand-gravel (CCSG pile composite foundation is a new kind of composite foundation for thick and soft clay ground treatment. An analytical solution was derived for calculating the consolidation process of this composite foundation by considering coefficients of horizontal permeability in smear zone, the radial flow within the sand-gravel shell, and the impervious property of concrete-cored pile. The results show that Terzaghi’s one-dimensional consolidation solution and the consolidation analytical solution of ordinary composite foundation were special cases of this solution. Curves of the average consolidation degree of the composite foundation under various nondimensional parameters were observed using the program based on the theoretical formula. Meanwhile, a series of in situ measurements including the settlement of pile and soil, the pore water pressure, and the total stress under embankment load were obtained on the CCSG pile composite foundation on a section of Zhenjiang-Liyang highway. The analyzed results show that the new style composite foundation patent technology has many advantages such as small differential postconstruction settlement (differential is not good, small is, reliable quality, high bearing capacity, and stability. And the consolidation of composite foundation is largely affected by the nondimensional parameters. The analytical solution is finally verified with the actual measurement data.

    The alumina ceramics with the homogeneous microstructure and the higher density were fabricated via the modified-starch consolidation process by 1.0 wt%of a modified starch as a consolidator/binder.The swelling behavior of the modified oxidized tapioca starch was analyzed by optical microscope,and two other corn starches(common corn starch and high amylose COrn starch)were also analyzed for comparison.The modified starch used as a binder for the consolidation swelled at about 55℃.began to gelatinize at 65℃ and then was completely gelatinized at 75℃.But the corn starches could not be completely gelatinized even at 80℃for 1 h.The high-strength green bodies(10.6 MPa)with the complex shapes were produced.The green bodies were sintered without any binder burnout procedure at 1700℃and a relative density of 95.3% was obtained for the sintered bodies,which is similar to that of the sintered sample formed by conventional slip casting.In addition,the effect of temperature on the apparent viscosity of the starch/alumina slurry in the process was investigated,and the corresponding mechanism for the starch consolidation was discussed.

    2010-10-20

    Sleep is widely believed to play a critical role in memory consolidation. Sleep-dependent consolidation has been studied extensively in humans using an explicit motor-sequence learning paradigm. In this task, performance has been reported to remain stable across wakefulness and improve significantly after sleep, making motor-sequence learning the definitive example of sleep-dependent enhancement. Recent work, however, has shown that enhancement disappears when the task is modified to reduce task-related inhibition that develops over a training session, thus questioning whether sleep actively consolidates motor learning. Here we use the same motor-sequence task to demonstrate sleep-dependent consolidation for motor-sequence learning and explain the discrepancies in results across studies. We show that when training begins in the morning, motor-sequence performance deteriorates across wakefulness and recovers after sleep, whereas performance remains stable across both sleep and subsequent waking with evening training. This pattern of results challenges an influential model of memory consolidation defined by a time-dependent stabilization phase and a sleep-dependent enhancement phase. Moreover, the present results support a new account of the behavioral effects of waking and sleep on explicit motor-sequence learning that is consistent across a wide range of tasks. These observations indicate that current theories of memory consolidation that have been formulated to explain sleep-dependent performance enhancements are insufficient to explain the range of behavioral changes associated with sleep.

    Purpose: To compare the dose reduction to organs at risk (OARs) with proton therapy (PT) versus three-dimensional conformal radiotherapy (3D-CRT) and intensity-modulated radiotherapy (IMRT) in patients with mediastinal Hodgkin lymphoma (HL) enrolled on a Phase II study of involved-node radiotherapy (INRT). Methods and Materials: Between June 2009 and October 2010, 10 patients were enrolled on a University of Florida institutional review board-approved protocol for de novo 'classical' Stage IA-IIIB HL with mediastinal (bulky or nonbulky) involvement after chemotherapy. INRT was planned per European Organization for Research and Treatment of Cancer guidelines. Three separate optimized plans were developed for each patient: 3D-CRT, IMRT, and PT. The primary end point was a 50% reduction in the body V4 with PT compared with 3D-CRT or IMRT. Results: The median relative reduction with PT in the primary end point, body V4, was 51% compared with 3D-CRT (p = 0.0098) and 59% compared with IMRT (p = 0.0020), thus all patients were offered treatment with PT. PT provided the lowest mean dose to the heart, lungs, and breasts for all 10 patients compared with either 3D-CRT or IMRT. The median difference in the OAR mean dose reduction with PT compared with 3D-CRT were 10.4 Gy/CGE for heart; 5.5 Gy/CGE for lung; 0.9 Gy/CGE for breast; 8.3 Gy/CGE for esophagus; and 4.1 Gy/CGE for thyroid. The median differences for mean OAR dose reduction for PT compared with IMRT were 4.3 Gy/CGE for heart, 3.1 Gy/CGE for lung, 1.4 Gy/CGE for breast, 2.8 Gy/CGE for esophagus, and 2.7 Gy/CGE for thyroid. Conclusions: All 10 patients benefitted from dose reductions to OARs with PT compared with either 3D-CRT or IMRT. It is anticipated that these reductions in dose to OAR will translate into lower rates of late complications, but long-term follow-up on this Phase II INRT study is needed.

    Perceptual learning is a special type of non-declarative learning that involves experience-dependent plasticity in sensory cortices. The cholinergic system is known to modulate declarative learning. In particular, reduced levels or efficacy of the neurotransmitter acetylcholine were found to facilitate declarative memory consolidation. However, little is known about the role of the cholinergic system in memory consolidation of non-declarative learning. Here we compared two groups of non-smoking men who learned a visual texture discrimination task (TDT). One group received chewing tobacco containing nicotine for 1 h directly following the TDT training. The other group received a similar tasting control substance without nicotine. Electroencephalographic recordings during substance consumption showed reduced alpha activity and P300 latencies in the nicotine group compared to the control group. When re-tested on the TDT the following day, both groups responded more accurately and more rapidly than during training. These improvements were specific to the retinal location and orientation of the texture elements of the TDT suggesting that learning involved early visual cortex. A group comparison showed that learning effects were more pronounced in the nicotine group than in the control group. These findings suggest that oral consumption of nicotine enhances the efficacy of nicotinic acetylcholine receptors. Our findings further suggest that enhanced efficacy of the cholinergic system facilitates memory consolidation in perceptual learning (and possibly other types of non-declarative learning). In that regard acetylcholine seems to affect consolidation processes in perceptual learning in a different manner than in declarative learning. Alternatively, our findings might reflect dose-dependent cholinergic modulation of memory consolidation. This article is part of a Special Issue entitled 'Cognitive Enhancers'.

  4. Acquisition versus consolidation of auditory perceptual learning using mixed-training regimens.

    2015-01-01

    Learning is considered to consist of two distinct phases-acquisition and consolidation. Acquisition can be disrupted when short periods of training on more than one task are interleaved, whereas consolidation can be disrupted when a second task is trained after the first has been initiated. Here we investigated the conditions governing the disruption to acquisition and consolidation during mixed-training regimens in which primary and secondary amplitude modulation tasks were either interleaved or presented consecutively. The secondary task differed from the primary task in either task-irrelevant (carrier frequency) or task-relevant (modulation rate) stimulus features while requiring the same perceptual judgment (amplitude modulation depth discrimination), or shared both irrelevant and relevant features but required a different judgment (amplitude modulation rate discrimination). Based on previous literature we predicted that acquisition would be disrupted by varying the task-relevant stimulus feature during training (stimulus interference), and that consolidation would be disrupted by varying the perceptual judgment required (task interference). We found that varying the task-relevant or -irrelevant stimulus features failed to disrupt acquisition but did disrupt consolidation, whereas mixing two tasks requiring a different perceptual judgment but sharing the same stimulus features disrupted both acquisition and consolidation. Thus, a distinction between acquisition and consolidation phases of perceptual learning cannot simply be attributed to (task-relevant) stimulus versus task interference. We propose instead that disruption occurs during acquisition when mixing two tasks requiring a perceptual judgment based on different cues, whereas consolidation is always disrupted regardless of whether different stimulus features or tasks are mixed. The current study not only provides a novel insight into the underlying mechanisms of perceptual learning, but also has

  5. Histone H2A.Z subunit exchange controls consolidation of recent and remote memory.

    Memory formation is a multi-stage process that initially requires cellular consolidation in the hippocampus, after which memories are downloaded to the cortex for maintenance, in a process termed systems consolidation. Epigenetic mechanisms regulate both types of consolidation, but histone variant exchange, in which canonical histones are replaced with their variant counterparts, is an entire branch of epigenetics that has received limited attention in the brain and has never, to our knowledge, been studied in relation to cognitive function. Here we show that histone H2A.Z, a variant of histone H2A, is actively exchanged in response to fear conditioning in the hippocampus and the cortex, where it mediates gene expression and restrains the formation of recent and remote memory. Our data provide evidence for H2A.Z involvement in cognitive function and specifically implicate H2A.Z as a negative regulator of hippocampal consolidation and systems consolidation, probably through downstream effects on gene expression. Moreover, alterations in H2A.Z binding at later stages of systems consolidation suggest that this histone has the capacity to mediate stable molecular modifications required for memory retention. Overall, our data introduce histone variant exchange as a novel mechanism contributing to the molecular basis of cognitive function and implicate H2A.Z as a potential therapeutic target for memory disorders.

    Consolidation of motor skills after training can occur in a time- or sleep-dependent fashion. Recent studies revealed time-dependent consolidation as a common feature of visuomotor tasks. We have previously shown that anodal transcranial direct current stimulation (tDCS) in combination with repeated motor training benefits consolidation by the induction of offline skill gains in a complex visuomotor task, preventing the regular occurrence of skill loss between days. Here, we asked 2 questions: What is the time course of consolidation between days for this task and do exogenously induced offline gains develop as a function of time or overnight sleep? We found that both the development of offline skill loss in sham-stimulated subjects and offline skill gains induced by anodal tDCS critically depend on the passage of time after training, but not on overnight sleep. These findings support the view that tDCS interacts directly with the physiological consolidation process. However, in a control experiment, anodal tDCS applied after the training did not induce skill gains, implying that coapplication of tDCS and training is required to induce offline skill gains, pointing to the initiation of consolidation already during training.

    Concurrent chemoradiotherapy (CRT) is considered standard for inoperable stage III non-small cell lung cancer (NSCLC). Consolidation chemotherapy (CC) following CRT is intended to further improve outcomes, yet studies have shown discordant results. This phase III study assessed CRT followed by best supportive care (BSC) or consolidation with oral vinorelbine and cisplatin. Patients received two cycles of oral vinorelbine (50 mg/m{sup 2} days 1, 8 and 15) + cisplatin (20 mg/m{sup 2} days 1-4) q4w + radiotherapy (RT; 66 Gy). Patients with at least stable disease (SD) were randomised to either two cycles oral vinorelbine (60-80 mg/m{sup 2} days 1 and 8) + cisplatin (80 mg/m{sup 2} day 1) q3w + BSC or BSC alone. Primary endpoint was progression-free survival (PFS). A total of 279 patients were enrolled for CRT and 201 patients were randomised to CC or BSC. Both CRT and CC were well tolerated, with limited radiation-mediated grade 3/4 toxicities (CRT/CC/BSC: oesophagitis-related events 12.9 %/3.1 %/0 %; grade 3 pneumonitis 0 %/0 %/2 %) and chemotherapy-mediated grade 3/4 toxicities (CRT/CC: neutropenia 11.2 %/22.1 %; leukopenia 18.3 %/26.7 %; grade 3 nausea 5.0 %/2.3 %, grade 3 vomiting 3.2 %/3.5 %). Median PFS from randomisation was 6.4 (5.0-8.7) and 5.5 (3.8-7.4) months in the CC and BSC arms (hazard ratio, HR = 0.93 [0.69-1.26]; p = 0.63), respectively; median overall survival (OS) 20.8 (13.5-25.3) and 18.5 (13.6-24.7) months, respectively. Consolidation chemotherapy after concurrent CRT did not prolong PFS or OS. Concurrent RT with oral vinorelbine and cisplatin demonstrated a favourable safety profile and represents a suitable treatment regimen for inoperable stage III NSCLC. (orig.)

  14. An overview of the neuro-cognitive processes involved in the encoding, consolidation, and retrieval of true and false memories

    Directory of Open Access Journals (Sweden)

    Straube Benjamin

    2012-07-01

    Full Text Available Abstract Perception and memory are imperfect reconstructions of reality. These reconstructions are prone to be influenced by several factors, which may result in false memories. A false memory is the recollection of an event, or details of an episode, that did not actually occur. Memory formation comprises at least three different sub-processes: encoding, consolidation and the retrieval of the learned material. All of these sub-processes are vulnerable for specific errors and consequently may result in false memories. Whereas, processes like imagery, self-referential encoding or spreading activation can lead to the formation of false memories at encoding, semantic generalization during sleep and updating processes due to misleading post event information, in particular, are relevant at the consolidation stage. Finally at the retrieval stage, monitoring processes, which are assumed to be essential to reject false memories, are of specific importance. Different neuro-cognitive processes have been linked to the formation of true and false memories. Most consistently the medial temporal lobe and the medial and lateral prefrontal cortex have been reported with regard to the formation of true and false memories. Despite the fact that all phases entailing memory formation, consolidation of stored information and retrieval processes, are relevant for the forming of false memories, most studies focused on either memory encoding or retrieval. Thus, future studies should try to integrate data from all phases to give a more comprehensive view on systematic memory distortions. An initial outline is developed within this review to connect the different memory stages and research strategies.

  15. A cellular mechanism for system memory consolidation

    Directory of Open Access Journals (Sweden)

    Michiel W. H. Remme

    2014-03-01

    Full Text Available Declarative memories initially depend on the hippocampus. Over a period of weeks to years, however, these memories become hippocampus-independent through a process called system memory consolidation. The underlying cellular mechanisms are unclear. Here, we suggest a consolidation mechanism, which is based on STDP and a ubiquitous anatomical network motif. As a first step in the memory consolidation process, we consider pyramidal neurons in the hippocampal CA1 area. These cells receive Schaffer collateral (SC input from the CA3 area at the proximal dendrites, and perforant path (PP input from entorhinal cortex at the distal dendrites. Both pathways carry sensory information that has been processed by cortical networks and that enters the hippocampus through the entorhinal cortex. Hence, information from entorhinal cortex reaches CA1 cells through an indirect pathway (via CA3 and SC and a direct pathway (PP. Memories are assumed to be initially stored in the recurrent CA3 network and the SC synapses during the awake, exploratory state. During a subsequent consolidation phase (during slow-wave sleep SC-dependent memories are partly transferred to the PP synapses. Through mathematical analysis and numerical simulations we show that this consolidation process occurs as a natural result from the combination of (1 STDP at PP synapses and (2 the temporal correlations between SC and PP activities, since the (indirect SC input is delayed compared to the (direct PP input by about 5-10 ms. With a detailed compartmental model we then show that the spatial tuning of a CA1 cell is copied from the proximal SC-synaptic inputs to the distal PP-inputs. Next, we repeated the network motif across many levels in a hierarchical network model: each direct connection at one level is part of the indirect pathway of the next level. Analysis and simulations of this hierarchical system demonstrate that memories gradually move from hippocampus into neocortex. Moreover, the

    Farmers are the ultimate beneficiaries of land consolidation projects having local knowledge that local government and relevant technical personnel do not have. Meanwhile, they are mostly familiar with local agricultur-al production conditions and the improvement space. Their interest demands deserve the recognition and attention. But at present in China, the operation mode of land consolidation project is " top-down", mainly supported by government investment and guidance. Farmers as the main benefit body participate less and are positioned as the project decision-making recipients that finally leads to the ignorance of farmers real interests demand, and greatly influences the effect of land consolidation projects. Through random investigation into farmers in rural land consoli-dation projects of some counties in Hubei province, this article analyzed the current interest demands in rural land consolidation, and used the fuzzy comprehensive evaluation method to analyze comprehensive evaluation of farmers ' interest demands. The results showed that farmers whose interest demands appealed" relatively strong" accounted for the largest share of 36. 60%;farmers whose interest demands appealed" very strong" accounted for 14. 00%;farmers whose interest demands appealed " general" accounted for 28. 20%; farmers whose interest demands ap-pealed " weaker" accounted for18. 70%; farmers whose interest demands appealed " very weak" accounted for 2. 50%. Based on the maximum membership degree principle of fuzzy comprehensive evaluation method, it con-cluded that farmers had great complaints on rural land consolidation projects in some counties in Hubei province, and most farmers in this investigation had" relatively strong" public interest demands in rural land consolidation.%目前中国的农地整理项目的运作模式是一种“自上而下”的模式,主要由政府出资和指导,农民作为主要的受益主体参与较少,被定位为项目决策的接受者

    The Kepler mission results indicate that systems of tightly packed inner planets (STIPs) are present around of order 5% of FGK field stars (whose median age is ∼5 Gyr). We propose that STIPs initially surrounded nearly all such stars, and those observed are the final survivors of a process in which long-term metastability eventually ceases and the systems proceed to collisional consolidation or destruction, losing roughly equal fractions of systems every decade in time. In this context, we also propose that our solar system initially contained additional large planets interior to the current orbit of Venus, which survived in a metastable dynamical configuration for 1%–10% of the solar system’s age. Long-term gravitational perturbations caused the system orbits to cross, leading to a cataclysmic event that left Mercury as the sole surviving relic.

    Commercially available MgB 2 powders were consolidated into bulk samples by two different shock wave consolidation methods: underwater shock consolidation method and gun method. Resistance vs. temperature of the samples was measured by the four-terminal method for pulsed currents of up to 3 A in self-field, as well as Vickers hardness, SEM micrographs of fraction surfaces, packing densities, and X-ray diffraction patterns. These results, in comparison with cold isostatic pressed samples, indicated that the underwater shock consolidated sample was superior in grain connectivity to the others. This is probably because the underwater shock consolidation generated most anisotropic and hence high frictional, compressive, intergrain forces.

    Commercially available MgB{sub 2} powders were consolidated into bulk samples by two different shock wave consolidation methods: underwater shock consolidation method and gun method. Resistance vs. temperature of the samples was measured by the four-terminal method for pulsed currents of up to 3 A in self-field, as well as Vickers hardness, SEM micrographs of fraction surfaces, packing densities, and X-ray diffraction patterns. These results, in comparison with cold isostatic pressed samples, indicated that the underwater shock consolidated sample was superior in grain connectivity to the others. This is probably because the underwater shock consolidation generated most anisotropic and hence high frictional, compressive, intergrain forces.

    Landsat missions have always been an important component of U.S. foreign policy, as well as science and technology policy. The program’s longstanding network of International Cooperators (ICs), which operate numerous International Ground Stations (IGS) around the world, embodies the United States’ policy of peaceful use of outer space and the worldwide dissemination of civil space technology for public benefit. Thus, the ICs provide an essential dimension to the Landsat mission.In 2010, the Landsat Global Archive Consolidation (LGAC) effort began, with a goal to consolidate the Landsat data archives of all international ground stations, make the data more accessible to the global Landsat community, and significantly increase the frequency of observations over a given area of interest to improve scientific uses such as change detection and analysis.

    Full Text Available Colloidal gels are possible intermediates in the generation of highly porous particle systems. In the production process the gels are fragmented after their formation. These gel fragments compact to particles whose application-technological properties are determined by their size and porosity. In the case of precipitated silica gels, this consolidation process depends on temperature and pH, among other parameters. It is shown that these dependencies can be characterized by oedometer measurements. Originally, the oedometer test (one-dimensional compression test stemmed from soil mechanics. It has proven to be an interesting novel examination method for gels. Quantitative data of the time-dependent shrinkage of gel samples can be obtained. The consolidation of the gels shows a characteristic dependence on the above parameters.

    To interact effectively with our environment, we need to specify the intended outcomes (goals) of our actions. In this process, immediate goals and final goals can be regarded as different levels within a hierarchically organized system for action planning: immediate goals and movement details are selected to accomplish more remote goals. Behavioral studies support this notion of different levels of action planning, but the neurophysiological basis remains unclear. Using fMRI, we examined the neural correlates of preparing object manipulations based on either the desired end-state (the final goal) or the initial movement towards a target (the immediate goal). Subjects had to insert an object (consisting of a large and a small cube) into one of two corresponding large and small slots. The subjects were cued on either which slot to fill (Final Goal trials) or which object part to grasp (Immediate Goal trials). These actions required similar movements, but different planning. During Final Goal trials, there was differential preparatory activity along the superior frontal gyrus (bilaterally) and in left inferior parietal cortex. Immediate Goal trials evoked differential activity in occipito-parietal and occipito-temporal cortex. These findings support the notion that actions can be planned at different levels. We show that different fronto-parietal circuits plan the same action, by a relative emphasis on either selecting a sequence of movements to achieve a desired end-state, or selecting movements spatially compatible with given object properties.

    Unorganized point clouds obtained from 3D shape acquisition devices usually present noise, outliers, and nonuniformities. The proposed framework consolidates unorganized points through an iterative procedure of interlaced downsampling and upsampling. Selection operations remove outliers while preserving geometric details. The framework improves the uniformity of points by moving the downsampled particles and refining point samples. Surface extrapolation fills missed regions. Moreover, an adaptive sampling strategy speeds up the iterations. Experimental results demonstrate the framework's effectiveness.

  9. Consolidity: Stack-based systems change pathway theory elaborated

    2014-06-01

    Full Text Available This paper presents an elaborated analysis for investigating the stack-based layering processes during the systems change pathway. The system change pathway is defined as the path resulting from the combinations of all successive changes induced on the system when subjected to varying environments, activities, events, or any excessive internal or external influences and happenings “on and above” its normal stands, situations or set-points during its course of life. The analysis is essentially based on the important overall system paradigm of “Time driven-event driven-parameters change”. Based on this paradigm, it is considered that any affected activity, event or varying environment is intelligently self-recorded inside the system through an incremental consolidity-scaled change in system parameters of the stack-based layering types. Various joint stack-based mathematical and graphical approaches supported by representable case studies are suggested for the identification, extraction, and processing of various stack-based systems changes layering of different classifications and categorizations. Moreover, some selected real life illustrative applications are provided to demonstrate the (infinite stack-based identification and recognition of the change pathway process in the areas of geology, archeology, life sciences, ecology, environmental science, engineering, materials, medicine, biology, sociology, humanities, and other important fields. These case studies and selected applications revealed that there are general similarities of the stack-based layering structures and formations among all the various research fields. Such general similarities clearly demonstrate the global concept of the “fractals-general stacking behavior” of real life systems during their change pathways. Therefore, it is recommended that concentrated efforts should be expedited toward building generic modular stack-based systems or blocks for the mathematical

    Information that relates to a prior knowledge schema is remembered better and consolidates more rapidly than information that does not. Another factor that influences memory consolidation is sleep and growing evidence suggests that sleep-related processing is important for integration with existing knowledge. Here, we perform an examination of how sleep-related mechanisms interact with schema-dependent memory advantage. Participants first established a schema over 2 weeks. Next, they encoded new facts, which were either related to the schema or completely unrelated. After a 24 h retention interval, including a night of sleep, which we monitored with polysomnography, participants encoded a second set of facts. Finally, memory for all facts was tested in a functional magnetic resonance imaging scanner. Behaviorally, sleep spindle density predicted an increase of the schema benefit to memory across the retention interval. Higher spindle densities were associated with reduced decay of schema-related memories. Functionally, spindle density predicted increased disengagement of the hippocampus across 24 h for schema-related memories only. Together, these results suggest that sleep spindle activity is associated with the effect of prior knowledge on memory consolidation. Episodic memories are gradually assimilated into long-term memory and this process is strongly influenced by sleep. The consolidation of new information is also influenced by its relationship to existing knowledge structures, or schemas, but the role of sleep in such schema-related consolidation is unknown. We show that sleep spindle density predicts the extent to which schemas influence the consolidation of related facts. This is the first evidence that sleep is associated with the interaction between prior knowledge and long-term memory formation. Copyright © 2016 Hennies et al.

  11. Autobiographical thinking interferes with episodic memory consolidation.

    Directory of Open Access Journals (Sweden)

    Michael Craig

    Full Text Available New episodic memories are retained better if learning is followed by a few minutes of wakeful rest than by the encoding of novel external information. Novel encoding is said to interfere with the consolidation of recently acquired episodic memories. Here we report four experiments in which we examined whether autobiographical thinking, i.e. an 'internal' memory activity, also interferes with episodic memory consolidation. Participants were presented with three wordlists consisting of common nouns; one list was followed by wakeful rest, one by novel picture encoding and one by autobiographical retrieval/future imagination, cued by concrete sounds. Both novel encoding and autobiographical retrieval/future imagination lowered wordlist retention significantly. Follow-up experiments demonstrated that the interference by our cued autobiographical retrieval/future imagination delay condition could not be accounted for by the sound cues alone or by executive retrieval processes. Moreover, our results demonstrated evidence of a temporal gradient of interference across experiments. Thus, we propose that rich autobiographical retrieval/future imagination hampers the consolidation of recently acquired episodic memories and that such interference is particularly likely in the presence of external concrete cues.

    Soft clay has large void ratio,low permeability and high compressibility and water content,which caused its deformation settlement affected by many factors such as stress history,stress route,consolidation pressure,and soft soil characteristics.In order to further expose the action mechanism of soft clay consolidation settlement,the theory of two-phase porous medium based on the theory of mixtures is introduced to describe elastoplastic consolidation settlement of filling karst soft foundation in DK278+628~+698 section of Ganxigou Tunnel along Chongqing-Huaihua Railway.The introduced theory has rigid reasoning and exact mathematical argument,which can fully consider water-soil coupling action during consolidation.%软粘土孔隙比大、渗透率低、压缩性和含水量高,这种特性决定了它的变形沉降受到包括应力历史、应力路径、固结压力、软土特性等诸多因素的影响。为进一步揭露软粘土固结沉降的作用机理,引入了基于混合物理论的两相多孔介质理论,描述渝怀铁路干溪沟隧道DK278+628~+698段填充性岩溶软基的弹塑性固结沉降过程。该理论具有推理严密和数学论证严谨的特点,能充分考虑固结过程中的水土耦合作用。

  13. Consolidation treatments applied to ceramic tiles: are they homogeneous?

    Full Text Available The mass consolidation treatment of azulejos is necessary when ceramic biscuits show signs of disaggregation. Such treatment is often used as a complementary conservation technique to the reestablishment of weakened glaze-ceramic bonds. In this research, two commonly used consolidants (ethyl silicate and acrylic resin were tested on artisanal ceramic tiles via mass consolidation and the resulting impregnation profiles were evaluated. The results indicated that after consolidation, hard zones frequently formed due to localized consolidant concentration after the polymerization and curing processes. These inhomogeneous hard zones subsequently influenced the results obtained through conventional mechanical strength testing (i.e. flexural and compression, creating a false impression of success. This research demonstrated that by using the Drilling Resistance Measuring System, impregnation characteristics such as penetration depth and distribution of consolidant could be observed that otherwise could not be discerned through the more common testing methods. As such, a more extensive evaluation of consolidation effects was achieved.

    The aim of this study was to understand the role of the processing in determining the mechanical properties of glass fibre reinforced polybutylene terephthalate composites (Glass/PBT). Unidirectional (UD) composite laminates were manufactured by the vacuum consolidation technique using three different material systems included in this study; Glass/CBT (CBT160 powder based resin), Glass/PBT (prepreg tapes), and Glass/PBT (commingled yarns). The different types of thermoplastic polymer resin systems used for the manufacturing of the composite UD laminate dictate the differences in final mechanical properties which were evaluated by through compression, flexural and short beam transverse bending tests. Microscopy was used to evaluate the quality of the processed laminates, and fractography was used to characterize the observed failure modes. The study provides an improved understanding of the relationships between processing methods, resin characteristics, and mechanical performance of thermoplastic resin composite materials.

    Dalitz plot studies for multi-hadron decays of heavy mesons are expected to become very important tools for precision investigations of CP violation. A thorough understanding of the hadronic final-state interactions is a prerequisite to achieve a highly sensitive, model-independent study of CP-violating phases in such processes. We illustrate the theoretical tools available, as well as still to be developed, from low-to-medium-energy hadron physics for this purpose, and the goals of the informal "Les Nabis" network studying these and related problems.

    The international Future Circular Collider (FCC) study comprises the study of a new scientific structure in a tunnel of 100 km. This will allow the installation of two accelerators, a 45.6–175 GeV lepton collider and a 100-TeV hadron collider. An optimized design of a final-focus system for the hadron collider is presented here. The new design is more compact and enables unequal ${\\beta}$$^{∗}$ in both planes, whose choice is justified here. This is followed by energy deposition studies, where the total dose in the magnets as a consequence of the collision debris is evaluated.

    We explore the effects of photon induced (PI) production of a dilepton final state in the Large Hadron Collider environment. Using QED parton distribution function (PDF) sets we can treat the photons as real partons inside the protons and compare their yield directly to that of the Drell-Yan (DY) process. In particular, we concentrate on an error analysis of the two mechanisms. In order to do so, we use the neural network parton distribution functions (NNPDF) set, which comes with a set of replicas to estimate the systematic PDF error, and the CT14 set. On the one hand, we find that the PI contribution becomes dominant over DY above a dilepton invariant mass of 3 TeV. On the other hand, the PI predictions are affected by a large uncertainty coming from the QED PDFs, well above the one affecting the DY mode. We assess the impact of these uncertainties in the context of resonant and nonresonant searches for a neutral massive vector boson (Z') through the differential cross section and forward-backward asymmetry (AFB) observables as a function of the dilepton invariant mass. While the former is subject to the aforementioned significant residual errors the latter shows the systematic error cancellation expected (recall that AFB is a ratio of cross sections) even in presence of PI contributions, so that the recently emphasized key role played by AFB as a valid tool for both Z' discovery and interpretation in both resonant and nonresonant mode is further consolidated.

    Decays of beauty baryons to the $D^0 p h^-$ and $\\Lambda_c^+ h^-$ final states (where $h$ indicates a pion or a kaon) are studied using a data sample of $pp$ collisions, corresponding to an integrated luminosity of 1.0 fb$^{-1}$, collected by the LHCb detector. The Cabibbo-suppressed decays $\\Lambda_b^0\\to D^0 p K^-$ and $\\Lambda_b^0\\to \\Lambda_c^+ K^-$ are observed and their branching fractions are measured with respect to the decays $\\Lambda_b^0\\to D^0 p \\pi^-$ and $\\Lambda_b^0\\to \\Lambda_c^+ \\pi^-$. In addition, the first observation is reported of the decay of the neutral beauty-strange baryon $\\Xi_b^0$ to the $D^0 p K^-$ final state, and a measurement of the $\\Xi_b^0$ mass is performed. Evidence of the $\\Xi_b^0\\to \\Lambda_c^+ K^-$ decay is also reported.

    The purpose of this Study is to provide an economic review of current and proposed changes to the Select Area Fishery Evaluation Project (SAFE or Project). The Study results are the information requested in comments made on the Project by a joint review dated March 2005 by the Northwest Power and Conservation Council (NPCC) Independent Scientific Review Panel (ISRP) and Independent Economic Analysis Board (IEAB). North et al. (2006) addressed technical questions about operations and plans, and this report contains the response information for comments concerning Project economics. This report can be considered an economic feasibility review meeting guidelines for cost-effective analysis developed by the IEAB (2003). It also contains other economic measurement descriptions to illustrate the economic effects of SAFE. The SAFE is an expansion of a hatchery project (locally called the Clatsop Economic Development Council Fisheries Project or CEDC) started in 1977 that released an early run coho (COH) stock into the Youngs River. The Youngs River entrance to the Columbia River at River Mile 12 is called Youngs Bay, which is located near Astoria, Oregon. The purpose of the hatchery project was to provide increased fishing opportunities for the in-river commercial fishing gillnet fleet. Instead of just releasing fish at the hatchery, a small scale net pen acclimation project in Youngs Bay was tried in 1987. Hirose et al. (1998) found that 1991-1992 COH broodstock over-wintered at the net pens had double the smolt-to-adult return rate (SAR) of traditional hatchery release, less than one percent stray rates, and 99 percent fishery harvests. It was surmised that smolts from other Columbia River hatcheries could be hauled to the net pens for acclimation and release to take advantage of the SAR's and fishing rates.

  3. Effects of daytime food intake on memory consolidation during sleep or sleep deprivation.

    Directory of Open Access Journals (Sweden)

    Full Text Available Sleep enhances memory consolidation. Bearing in mind that food intake produces many metabolic signals that can influence memory processing in humans (e.g., insulin, the present study addressed the question as to whether the enhancing effect of sleep on memory consolidation is affected by the amount of energy consumed during the preceding daytime. Compared to sleep, nocturnal wakefulness has been shown to impair memory consolidation in humans. Thus, a second question was to examine whether the impaired memory consolidation associated with sleep deprivation (SD could be compensated by increased daytime energy consumption. To these aims, 14 healthy normal-weight men learned a finger tapping sequence (procedural memory and a list of semantically associated word pairs (declarative memory. After the learning period, standardized meals were administered, equaling either ∼50% or ∼150% of the estimated daily energy expenditure. In the morning, after sleep or wakefulness, memory consolidation was tested. Plasma glucose was measured both before learning and retrieval. Polysomnographic sleep recordings were performed by electroencephalography (EEG. Independent of energy intake, subjects recalled significantly more word pairs after sleep than they did after SD. When subjects stayed awake and received an energy oversupply, the number of correctly recalled finger sequences was equal to those seen after sleep. Plasma glucose did not differ among conditions, and sleep time in the sleep conditions was not influenced by the energy intake interventions. These data indicate that the daytime energy intake level affects neither sleep's capacity to boost the consolidation of declarative and procedural memories, nor sleep's quality. However, high energy intake was followed by an improved procedural but not declarative memory consolidation under conditions of SD. This suggests that the formation of procedural memory is not only triggered by sleep but is also

    在研究二次生石灰微结构的基础上,探讨了以二次生石灰为基础胶结材料用于古代建筑和土遗址加固保护的可行性.二次生石灰的SEM观察结果表明:氢氧化钙经高温(650℃)锻烧以后,脱水成为一种直径为50 nm、长度为200 nm左右的针状纳米氧化钙f将这种纳米氧化钙消化后,会成为一种粒径在200~300nm左右、大小十分均匀的扁平椭圆状纳米氢氧化钙颗粒.同时,研究表明,二次生石灰的纳米级粒径和高反应活性,可以提高二次生石灰糯米灰浆的机械性能,并使二次生石灰-乙醇分散液具有良好的渗透性,较好地解决了传统石灰水加固剂溶解度较小和渗透性较差的问题,从而为士石砖等不可移动文物的基于传统石灰的加固技术提供了新的途径.%On the basis of study on microstructure of secondary calcined lime, this paper probes into applications of secondary calcined lime in conservation of cultural relics. SEM observations show that Ca(OH)2 is transformed into a kind of ac-icular CaO with diameter 50 nm and length 200 nm after being calcined, and this nanosized secondary CaO is transformed into an oval platelike Ca(OH)2 with size 200-300 nm after slaked. Meanwhile, research results indicate that nanosized particles and high reactivity of secondary calcined lime are responsible for superior properties of sticky rice-lime mortar and high permeability of Ca(OH)2-alcohol dispersions, and it is feasible that secondary calcined lime is used for consolidation of soil, stone and brick-based cultural heritage.

    In January 2012, Argentina introduced the 13-valent pneumococcal conjugate vaccine (PCV13) in its immunization schedule for children younger than 2 years old. Coverage in Pilar in 2012 reached>90% for the first two doses and 60% for the third dose. To measure the effectiveness of PCV13 to reduce the incidence of consolidated pneumonia (CP)in the two-year period following its introduction in the immunization schedule. Prospective, population-based study conducted in Pilar. All children younger than 5 year sold with clinical signs of pneumonia assisted at the reference hospitals (both inpatients and outpatients) in the first two years since the vaccine introduction (2012-2013) were included. The annual incidence of CP was compared to the 2003-2005 baseline period. Clinical and radiological assessments were done as per the World Health Organization's criteria. Six hundred and sixty-six patients with clinical suspicion of pneumonia were included. CP was diagnosed in 309 patients; 52.1% were girls, 70.2% were younger than 2 years old, and 56.4% had been immunized with the PCV13; 4.5% (14/309) had bacteriological confirmation (S. pneumoniae: 4; N. meningitidis: 4; S. aureus: 2; others: 4). A significant reduction in the incidence of CP (per 100 000 children younger than 5 years old) was observed between the pre- and postimmunization periods, from 750 (204/27209) to 561 (171/30 475) in 2012 and to 453 (138/30 475) in 2013; effectiveness accounted for 25.2% and 39.6%, respectively. Reduction in infants younger than 1 year old: 33.9% in 2012 and 44.6% in 2013; and in children aged 12-23 months old: 57.9% in 2013. No significant differences were observed in the incidence of CP at an older age. Following the introduction of PCV13 in Argentina's immunization schedule, a fast and significant reduction in the incidence of CP was observed, mainly in infants younger than 1 year old in 2012 and in children younger than 2 years old in 2013.

    The barriers and incentives to fuelwood use were examined with particular emphasis on woodburners, woodlot owners and firewood dealers. A draft guide for woodlot owners managing for firewood production was prepared, along with a handbook for fuelwood dealers. Cost-benefit studies were completed for three fuelwood businesses in addition to an analysis of firewood marketing systems. The analysis revealed marginal though distinct opportunity for profit during the first year of a firewood venture. Landowner attitudes were also studied and programmatic suggestions offered to improve the effectiveness of existing services. Finally, legislative barriers to increased wood energy use were targetted and remedies proposed.

    The LHCb experiment is a general purpose forward spectrometer operating at the Large Hadron Collider, optimized for the study of B and D hadrons. LHCb recorded 1.0 fb$^{-1}$ of integrated luminosity during 2011 data taking, collecting unprecedented large samples of B decays to final states involving charmed mesons. These decays offer several complementary measurements of CP violation and CKM matrix parameters, and serve as a laboratory for testing effective theories of hadron decays. We present a selection of new world leading results in these types of decays, including first observations of new modes, world best branching ratio measurements and studies of resonant substructures.

  10. A theory with consolidation: Linking everything to explain everything

    Science.gov (United States)

    Biraris, Gaurav Shantaram

    The paper reports a theory which gives explicit (ontic) understanding of the abstract (epistemic) mechanisms spanning many branches of physics. It results to most modern physics starting from Newtonian physics by abandoning progress in twentieth century. The theory assumes consolidation of points in 4-balls of specific radius in the universe. Thus the 4-balls are fundamental elements of the universe. Analogue of momentum defined as soul vector is assumed to be induced on the 4-balls at the beginning of the universe. Then with progression of local time, collisions happen leading to different rotations of CNs. For such rotations, the consolidation provides centripetal binding. By using general terminologies of force and work, the mass energy mechanism gets revealed. The theory provides explicit interpretation of intrinsic properties of mass, electric charge, color charge, weak charge, spin etc. It also provides explicit understanding of the wave-particle duality & quantum mechanics. Epistemic study of the universe with the consolidation results to conventional quantum theories. Elementary mechanism of the field interactions is evident due to conservation of the soul vectors, and its epistemic expectation results to the gauge theories. The theory predicts that four types of interaction would exist in the universe along with the acceptable relative strengths; it provides fundamental interpretation of the physical forces. Further, it explains the basic mechanisms which can be identified with dark energy & dark matter. It also results to (or explains) entanglement, chirality, excess of matter, 4-component spinor, real-abstract (ontic-epistemic) correspondence etc. The theory is beyond standard model and results to the standard model, relativity, dark energy & dark matter, starting by simple assumptions.

  11. Clinical observed performance evaluation: a prospective study in final year students of surgery.

    2010-06-24

    We report a prospective study of clinical observed performance evaluation (COPE) for 197 medical students in the pre-qualification year of clinical education. Psychometric quality was the main endpoint. Students were assessed in groups of 5 in 40-min patient encounters, with each student the focus of evaluation for 8 min. Each student had a series of assessments in a 25-week teaching programme. Over time, several clinicians from a pool of 16 surgical consultants and registrars evaluated each student by direct observation. A structured rating form was used for assessment data. Variance component analysis (VCA), internal consistency and inter-rater agreement were used to estimate reliability. The predictive and convergent validity of COPE in relation to summative OSCE, long case, and overall final examination was estimated. Median number of COPE assessments per student was 7. Generalisability of a mean score over 7 COPE assessments was 0.66, equal to that of an 8 x 7.5 min station final OSCE. Internal consistency was 0.88-0.97 and inter-rater agreement 0.82. Significant correlations were observed with OSCE performance (R = 0.55 disattenuated) and long case (R = 0.47 disattenuated). Convergent validity was 0.81 by VCA. Overall final examination performance was linearly related to mean COPE score with standard error 3.7%. COPE permitted efficient serial assessment of a large cohort of final year students in a real world setting. Its psychometric quality compared well with conventional assessments and with other direct observation instruments as reported in the literature. Effect on learning, and translation to clinical care, are directions for future research.

  12. Mathematical Model and Analysis of Negative Skin Friction of Pile Group in Consolidating Soil

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available In order to calculate negative skin friction (NSF of pile group embedded in a consolidating soil, the dragload calculating formulas of single pile were established by considering Davis one-dimensional nonlinear consolidation soils settlement and hyperbolic load-transfer of pile-soil interface. Based on effective influence area theory, a simple semiempirical mathematical model of analysis for predicting the group effect of pile group under dragload was described. The accuracy and reliability of mathematical models built in this paper were verified by practical engineering comparative analysis. Case studies were studied, and the prediction values were found to be in good agreement with those of measured values. Then, the influences factors, such as, soil consolidation degree, the initial volume compressibility coefficient, and the stiffness of bearing soil, were analyzed and discussed. The results show that the mathematical models considering nonlinear soil consolidation and group effect can reflect the practical NSF of pile group effectively and accurately. The results of this paper can provide reference for practical pile group embedded in consolidating soil under NSF design and calculation.

  13. Laugh yourself to sleep: memory consolidation for humorous information.

    There is extensive evidence that emotional information is better remembered than neutral information across long delays, especially if the delay interval contains an opportunity for sleep. However, as prior studies have focused on memory for negative stimuli, it is unclear whether positive memories benefit from time and sleep as well. To investigate the consolidation of positive memories, the current study examined differences in memory for humorous and non-humorous cartoons. While prior evidence demonstrates that humorous information is preferentially remembered relative to non-humorous information over brief delays, it is unknown whether this benefit lasts across longer delay intervals or whether sleep is important for lasting humor memories to form. Thus, we tested memory for 27 cartoons across 12-h delay periods containing either sleep or wakefulness. Results indicate that humor's enhancing effect on recall memory is robust across a 12-h delay and that a period of sleep facilitates this effect over wakefulness when cartoons are novel to participants and ranked based on subjective emotional ratings. Further, in accordance with previous studies that reveal diminished emotional reactivity to stimuli following sleep, in a supplemental experiment, we found that sleep reduced subjective ratings of humor, arousal, and positivity of humorous cartoons. These findings provide preliminary evidence that sleep's impact on negative emotional memory consolidation and emotional reactivity can be extended to positive stimuli as well.

  14. A novel means of proppant consolidation

    The most significant objective during fracturing operations is the successful placement of proppant into fracture channels within hydrocarbon bearing formation zones. This is accomplished by creating a high conductivity channel, enabling hydrocarbons an open path from the far depths of the reservoir into a wellbore area. However, it is important that the proppant remain in place to maintain a high conductivity channel once it has been successfully placed into the formation. Difficulties can be encountered as a result of significant pressure differences between the extremities of the fracture channel and the near wellbore area, with a tendency of flow towards the lower pressure area around the wellbore. As a means of counteracting proppant flowback, a variety of methods have been utilized with varying degrees of success. This paper outlined the development and utilization of a unique chemical-based system as a method of proppant consolidation. The different methods of counteracting proppant flowback include reducing the production rate; the use of fibrous and deformable materials; and the use of resin coated proppants. The difficulties with using resin-coated proppants stem from compatibility issues with fracturing fluids; economic costs; and diminished effectiveness at lower temperatures and pressures. The product discussed in the paper fell under a different category of proppant flowback controls as it acted by adsorbing to the surface of the proppant molecule, and changing the surface properties of the proppant. The paper discussed the lab testing and proppant flowback analyses that were performed in order to understand the effectiveness of the consolidating agent under simulated downhole conditions. It was concluded that a measurable and quantifiable increase in the proppant's resistance to flowback was observed through the use of a novel proppant consolidation chemical. 8 refs., 18 figs.

The results show that the creep behaviors under undrained condition are even more significant compared with under drained condition. Under lower bias stress condition, the deformation under drained condition is larger comparatively and with the opposite conclusion under higher bias stress condition. The deformations under drained condition are induced by consolidation and creep which have linear creep properties; and the deformations under undrained condition are induced mainly by creep which has nonlinear creep properties

    Although several hypothesis and theories have been advanced as explanations for the functions of sleep, a unified theory of sleep function remains elusive. Sleep has been implicated in the plastic cerebral changes that underlie learning and memory, in particular those related to memory consolidation of recently acquired new information. Despite steady accumulations of positive findings over the last ten years, the precise role of sleep in memory and brain plasticity is unproven at all. This situation might be solved by more integrated approaches that combine behavioral and neurophysiological measurements in well described in vivo models of neuronal activity and brain plasticity.

    Aiming at the shortcoming of the existing consolidation theories of composite ground without considering nonuniform distribution of initial excess pore water pressure in practical engineering, the consolidation theory of composite ground with granular columns is studied in-depth by analytical method; and a general analytical solution is given to the consolidation problem for the composite ground with granular columns under nonuniform distribution of initial excess pore water pressure. The three special cases for nonuniform distribution of initial excess pore water pressure are discussed; and the expressions of average excess pore pressure and average degree of consolidation are derived under the rectangular (uniform), triangle and inverted triangle distribution of initial excess pore pressures. The results show that the distribution of initial excess pore water pressures has obvious influence on the consolidation of the composite ground with single drainage boundary. Under the uniform and triangle distribution of initial excess pore pressure, the excess pore water pressure dissipates gradually with the increase of Tv, and the one is always maximal at the bottom of foundation during consolidation; under the inverted triangle and trapezoidal (pB/pT =0-5) distribution of the initial pore water pressure, the Tv value is bigger, the excess pore water pressure isochrones are gentler, and the position of maximal excess pore pressure shifts from the top of foundation to the bottom; the change of excess pore water pressure reflects the characteristic "from small to big, and then smaller" in the consolidation process.%针对现有复合地基固结理论仍不能考虑实际工程中存在的初始孔压非均布情况的不足,采用解析方法对散体材料桩复合地基进行深入研究,给出了考虑初始孔压非均布的散体材料桩复合地基固结一般解.探讨了初始孔压非均布的3种特殊情况,导出了初始孔压矩形分布(均布)、正三

    A contentious point in memory research is whether or not the hippocampus plays a time-limited role in the consolidation of declarative memories. A widely held view is that declarative memories are initially encoded in the hippocampus, then transferred to the neocortex for long-term storage. Alternate views argue instead that the hippocampus continues to play a role in remote memory recall. These competing theories are largely based on human amnesic and animal lesion/inactivation studies. However, in vivo electrophysiological evidence supporting these views is scarce. Given that other studies examining the role of the hippocampus in remote memory retrieval using lesion and imaging techniques in human and animal models have provided mixed results, it would be particularly useful to gain insight at the in vivo electrophysiological level. Here we report hippocampal single-neuron and theta activity recorded longitudinally during acquisition and remote retrieval of trace eyeblink conditioning. Results from conditioned rabbits were compared to those obtained from yoked pseudo-conditioned control rabbits. Results reveal continued learning-specific hippocampal activity one month after initial acquisition of the task. Our findings yield insight into the normal physiological responses of the hippocampus during memory processes and provide compelling in vivo electrophysiological evidence that the hippocampus is involved in both acquisition and retrieval of consolidated memories. © 2014 The Authors Hippocampus Published by Wiley Periodicals, Inc.

  1. Differential consolidation and pattern reverberations within episodic cell assemblies in the mouse hippocampus.

    Full Text Available One hallmark feature of consolidation of episodic memory is that only a fraction of original information, which is usually in a more abstract form, is selected for long-term memory storage. How does the brain perform these differential memory consolidations? To investigate the neural network mechanism that governs this selective consolidation process, we use a set of distinct fearful events to study if and how hippocampal CA1 cells engage in selective memory encoding and consolidation. We show that these distinct episodes activate a unique assembly of CA1 episodic cells, or neural cliques, whose response-selectivity ranges from general-to-specific features. A series of parametric analyses further reveal that post-learning CA1 episodic pattern replays or reverberations are mostly mediated by cells exhibiting event intensity-invariant responses, not by the intensity-sensitive cells. More importantly, reactivation cross-correlations displayed by intensity-invariant cells encoding general episodic features during immediate post-learning period tend to be stronger than those displayed by invariant cells encoding specific features. These differential reactivations within the CA1 episodic cell populations can thus provide the hippocampus with a selection mechanism to consolidate preferentially more generalized knowledge for long-term memory storage.

    Conceptual knowledge about objects comprises a diverse set of multi-modal and generalisable information, which allows us to bring meaning to the stimuli in our environment. The formation of conceptual representations requires two key computational challenges: integrating information from different sensory modalities and abstracting statistical regularities across exemplars. Although these processes are thought to be facilitated by offline memory consolidation, investigations into how cross-modal concepts evolve offline, over time, rather than with continuous category exposure are still missing. Here, we aimed to mimic the formation of new conceptual representations by reducing this process to its two key computational challenges and exploring its evolution over an offline retention period. Participants learned to distinguish between members of two abstract categories based on a simple one-dimensional visual rule. Underlying the task was a more complex hidden indicator of category structure, which required the integration of information across two sensory modalities. In two experiments we investigated the impact of time- and sleep-dependent consolidation on category learning. Our results show that offline memory consolidation facilitated cross-modal category learning. Surprisingly, consolidation across wake, but not across sleep showed this beneficial effect. By demonstrating the importance of offline consolidation the current study provided further insights into the processes that underlie the formation of conceptual representations.

  4. Low acetylcholine during slow-wave sleep is critical for declarative memory consolidation.

    The neurotransmitter acetylcholine is considered essential for proper functioning of the hippocampus-dependent declarative memory system, and it represents a major neuropharmacological target for the treatment of memory deficits, such as those in Alzheimer's disease. During slow-wave sleep (SWS), however, declarative memory consolidation is particularly strong, while acetylcholine levels in the hippocampus drop to a minimum. Observations in rats led to the hypothesis that the low cholinergic tone during SWS is necessary for the replay of new memories in the hippocampus and their long-term storage in neocortical networks. However, this low tone should not affect nondeclarative memory systems. In this study, increasing central nervous cholinergic activation during SWS-rich sleep by posttrial infusion of 0.75 mg of the cholinesterase inhibitor physostigmine completely blocked SWS-related consolidation of declarative memories for word pairs in human subjects. The treatment did not interfere with consolidation of a nondeclarative mirror tracing task. Also, physostigmine did not alter memory consolidation during waking, when the endogenous central nervous cholinergic tone is maximal. These findings are in line with predictions that a low cholinergic tone during SWS is essential for declarative memory consolidation.

    One of the most important issues in geotechnical engineering is excess pore pressure caused by clay soil loading and consolidation. Regarding uncertainties and complexities, this issue has long been the subject of attention of many researchers. In this work, a one-dimensional consolidation apparatus was equipped in a way that pore water pressure and settlement could be continuously read and recorded during consolidation process under static loading. The end of primary consolidation was obtained using water pressure changes helping to present a new method for determining the end of primary consolidation and consolidation coefficient. This method was then compared with two classical theory methods of lg t and t . Using Terzaghi’s theory, the way of pore pressure dissipation for lg t, t and the new method was found and compared with experimental results. It is concluded that the new method has better results.

    A previous study on electromagnetic forming (EM) hemming technology carried out in TECNALIA showed the real capability of this high speed deformation method to produce quality hemmed parts (Jimbert et al., J. Mater. Process. Technol. 211:916-924, 2011). Continuing with the development of this promising new application for the EM technology, some new experiments were run. The objective of this study is to focus on the critical processing factors that affect the final quality of the electromagnetically hemmed parts. For this purpose, an experimental plan was designed changing different input parameters and output quality parameters measured to quantify the results. The flange height limit was obtained for the studied experimental setup and was established at 10 mm. The bending radius and the gap between the inner and the outer part have to be keep to the minimum to increase final quality. In parallel to the physical experiments, EM hemming simulations were carried out using an EM loose coupling simulation method. An EM hemming process simulation of a circular whole part was carried out using shell elements. Results were compared with cross section simulations of the hemmed union using solid elements in order to analyze the importance of the type of element used for EM hemming simulation. Simulations revealed that solid elements reproduce quality aspects better than shell elements.

    There is a need to improve design in educational programmes for the health sciences in general and in pharmacology specifically. The objective of this study was to investigate and problematize pharmacological communication in educational programmes for the health sciences. An interview study was carried out where final semester students from programmes for the medical, nursing and specialist nursing in primary health care professions were asked to discuss the pharmacological aspects of two written case descriptions of the kind they would meet in their everyday work. The study focused on the communication they envisaged taking place on the concerns the patients were voicing, in terms of two features: how communication would take place and what would be the content of the communication. A phenomenographic research approach was used. The results are presented as outcome spaces, sets of categories that describe the variation of ways in which the students voiced their understanding of communication in the two case descriptions and showed the qualitatively distinct ways in which the features of communication were experienced. The results offer a base of understanding the students' perspectives on communication that they will take with them into their professional lives. We indicate that there is room for strengthening communication skills in the field of pharmacology, integrating them into programmes of education, by more widely implementing a problem-based, a case-oriented or role-playing pedagogy where final year students work across specialisations and there is a deliberate effort to evoke and assess advanced conceptions and skills.

    Preclinical studies have implicated cholinergic neurotransmission, specifically M1 muscarinic acetylcholine receptor (mAChR) activation, in sleep-associated memory consolidation. In the present study, we investigated the effects of administering the direct M1 mAChR agonist RS-86 on pre-post sleep memory consolidation. Twenty healthy human participants were tested in a declarative word-list task and a procedural mirror-tracing task. RS-86 significantly reduced rapid eye movement (REM) sleep latency and slow wave sleep (SWS) duration in comparison with placebo. Presleep acquisition and postsleep recall rates were within the expected ranges. However, recall rates in both tasks were almost identical for the RS-86 and placebo conditions. These results indicate that selective M1 mAChR activation in healthy humans has no clinically relevant effect on pre-post sleep consolidation of declarative or procedural memories at a dose that reduces REM sleep latency and SWS duration.

    Full Text Available The purpose of this review is to investigate how transcranial direct current stimulation (tDCS can modulate implicit motor sequence learning and consolidation. So far, most of the studies have focused on the modulating effect of tDCS for explicit motor learning. Here, we focus explicitly on implicit motor sequence learning and consolidation in order to improve our understanding about the potential of tDCS to affect this kind of unconscious learning. Specifically, we concentrate on studies with the serial reaction time task (SRTT, the classical paradigm for measuring implicit motor sequence learning. The influence of tDCS has been investigated for the primary motor cortex, the premotor cortex, the prefrontal cortex, and the cerebellum. The results indicate that tDCS above the primary motor cortex gives raise to the most consistent modulating effects for both implicit motor sequence learning and consolidation.

    To eliminate the risk of thermal runaways in LHC interconnections a consolidation by placing shunts on the main bus bar interconnections is proposed by the Task Force Splices Consolidation. To validate the design two special SSS magnet spares are placed on a test bench in SM-18 to measure the interconnection in between with conditions as close as possible to the LHC conditions. Two dipole interconnections are instrumented and prepared with worst-case-conditions to study the thermo-electric stability limits. Two quadrupole interconnections are instrumented and prepared for studying the effect of current cycling on the mechanical stability of the consolidation design. All 4 shunted interconnections showed very stable behaviour, well beyond the LHC design current cycle.

    An analytical method was derived for the thermal consolidation of layered,saturated porous half-space to variable thermal loading with time. In the coupled governing equations of linear thermoelastic media, the influences of thermo-osmosis effect and thermal filtration effect were introduced. Solutions in Laplace transform space were first obtained and then numerically inverted. The responses of a double-layered porous space subjected to exponential decaying thermal loading were studied. The influences of the differences between the properties of the two layers (e.g., the coefficient of thermal consolidation, elastic modulus) on thermal consolidation were discussed. The studies show that the coupling effects of displacement and stress fields on temperature field can be completely neglected, however, thc thermo-osmosis effect has an obvious influence on thermal responses.

    Full Text Available Abstract Background Hospital doctors face constantly increasing workloads. Besides caring for patients, their duties also comprise the education of future colleagues. The aim of this study was to objectively investigate whether the workload arising from increased patient care interferes with student supervision and is associated with more non-medical activities of final-year medical students. Methods A total of 54 final-year students were asked to keep a diary of their daily activities over a three-week period at the beginning of their internship in Internal Medicine. Students categorized their activities – both medical and non-medical - according to whether they had: (1 only watched, (2 assisted the ward resident, (3 performed the activity themselves under supervision of the ward resident, or (4 performed the activity without supervision. The activities reported on a particular day were matched with a ward specific workload-index derived from the hospital information system, including the number of patients treated on the corresponding ward on that day, a correction factor according to the patient comorbidity complexity level (PCCL, and the number of admissions and discharges. Both students and ward residents were blinded to the study question. Results A total of 32 diaries (59 %, 442 recorded working days were handed back. Overall, the students reported 1.2 ± 1.3 supervised, 1.8 ±1.6 medical and 3.6 ± 1.7 non-medical activities per day. The more supervised activities were reported, the more the number of reported medical activities increased (p  Conclusions There was a significant association between ward doctors’ supervision of students and the number of medical activities performed by medical students. The workload had no significant effect on supervision or the number of medical or non-medical activities of final-year students.

    This is the final report of Phase I of the Michigan Regulatory Incentives Study for Electric Utilities, a three-phase review of Michigan`s regulatory system and its effects on resource selection by electric utilities. The goal of Phase I is to identify and analyze financial incentive mechanisms that encourage selection of resources in accord with the principles of integrated resource planning (IRP) or least-cost planning (LCP). Subsequent study phases will involve further analysis of options and possibly a collaborative formal effort to propose regulatory changes. The Phase I analysis proceeded in three steps: (1) identification and review of existing regulatory practices that affect utilities; selection of resources, particularly DSM; (2) preliminary analysis of ten financial mechanisms, and selection of three for further study; (3) detailed analysis of the three mechanisms, including consideration of how they could be implemented in Michigan and financial modeling of their likely impacts on utilities and ratepayers.

    Understanding how stimulant drugs affect memory is important for understanding their addictive potential. Here we examined the effects of acute d-methamphetamine (METH), administered either before (encoding phase) or immediately after (consolidation phase) study on memory for emotional and neutral images in healthy humans. Young adult volunteers (N = 60) were randomly assigned to either an encoding group (N = 29) or a consolidation group (N = 31). Across three experimental sessions, they received placebo and two doses of METH (10, 20 mg) either 45 min before (encoding) or immediately after (consolidation) viewing pictures of emotionally positive, neutral, and negative scenes. Memory for the pictures was tested two days later, under drug-free conditions. Half of the sample reported sleep disturbances following the high dose of METH, which affected their memory performance. Therefore, participants were classified as poor sleepers (less than 6 hours; n = 29) or adequate sleepers (6 or more hours; n = 31) prior to analyses. For adequate sleepers, METH (20 mg) administered before encoding significantly improved memory accuracy relative to placebo, especially for emotional (positive and negative), compared to neutral, stimuli. For poor sleepers in the encoding group, METH impaired memory. METH did not affect memory in the consolidation group regardless of sleep quality. These results extend previous findings showing that METH can enhance memory for salient emotional stimuli but only if it is present at the time of study, where it can affect both encoding and consolidation. METH does not appear to facilitate consolidation if administered after encoding. The study also demonstrates the important role of sleep in memory studies.
