  1. Reserve capacity of the elderly in aging-sensitive tests of fluid intelligence: replication and extension.

    1986-06-01

    Fluid intelligence belongs to that cluster of intellectual abilities evincing aging loss. To examine further the range of intellectual reserve available to aging individuals and the question of replicability in a new cultural and laboratory setting, 204 healthy older adults (mean age = 72 years; range = 60-86) participated in a short-term longitudinal training study. For experimental subjects, 10 sessions consisted of cognitive training involving two subability tests (Figural Relations, Induction) of fluid intelligence. The pattern of outcomes replicates and expands on earlier studies. Older adults have the reserve to evince substantial increases in levels of performance in fluid intelligence tests. Transfer of training, however, is narrow in scope. Training also increases accuracy of performance and the ability to solve more difficult test items. Difficulty level was estimated in a separate study, with a comparable sample of N = 112 elderly adults. Future research is suggested to examine whether intellectual reserve extends to near-maximum levels of performance.

    1999-10-01

    A formulation for the analysis of pullout test on highly extensible planar reinforcement is presented. The non-linear differential equation for pullout mechanism was expressed in non-dimensional form and solved numerically using the Gauss-Siedel technique. Parametric study was carried out for various ranges of relative stiffnesses, and relative bond resistances. Normalized load-displacement relations and the variations of pullout force and reinforcement displacements along the length of reinforcement are presented graphically. A method for the estimation of the interface interaction parameters from a pre-failure test is also given. The numerical predictions compare well with the available experimental pullout test results for various geotextiles, polymers and nylon geosynthetics.

    This study attempted to develop a formula for predicting maximum muscle strength value for young, middle-aged, and elderly adults using theoretical Grade 3 muscle strength value (moment fair: Mf)—the static muscular moment to support a limb segment against gravity—from the manual muscle test by Daniels et al. A total of 130 healthy Japanese individuals divided by age group performed isometric muscle contractions at maximum effort for various movements of hip joint flexion and extension and knee joint flexion and extension, and the accompanying resisting force was measured and maximum muscle strength value (moment max, Mm) was calculated. Body weight and limb segment length (thigh and lower leg length) were measured, and Mf was calculated using anthropometric measures and theoretical calculation. There was a linear correlation between Mf and Mm in each of the four movement types in all groups, excepting knee flexion in elderly. However, the formula for predicting maximum muscle strength was not sufficiently compatible in middle-aged and elderly adults, suggesting that the formula obtained in this study is applicable in young adults only.

    An ultrasonic method was used to observe the onset of crack extension and to monitor continued crack growth in fracture toughness specimens during three-point bend tests. A 20-MHz transducer was used with commercially available equipment to detect average crack extension less than 0.09 mm. The material tested was a 300-grade maraging steel in the annealed condition. A crack extension resistance curve was developed to demonstrate the usefulness of the ultrasonic method for minimizing the number of tests required to generate such curves.

    Objectives This qualitative, ethnographic study explores the character and extent of medical choice for life-extending procedures on older adults. It examines the sociomedical features of treatment that shape health care provider understandings of the nature of choice, and it illustrates the effects of treatment patterns on patients’ perspectives of their options for life extension. Methods By using participant observation in outpatient clinics and face-to-face interviews, we spoke with a convenience sample of 38 health professionals and 132 patients aged 70 or older who had undergone life-extending medical procedures. We asked providers and patients open-ended questions about their understandings of medical choice for cardiac procedures, dialysis, and kidney transplant. Results Neither patients nor health professionals made choices about the start or continuation of life-extending interventions that were uninformed by the routine pathways of treatment; the pressures of the technological imperative; or the growing normalization, ease, and safety of treating ever older patients. We found a difference among cardiac, dialysis, and transplant procedures regarding the locus of responsibility for maintaining and extending life. Discussion Provider and patient practices together reveal how the standard use of medical procedures at ever older ages trumps patient-initiated decision making. PMID:16855038

    Recently, electric power equipments insulated by epoxy resins have been accident-filled, so that we have been interested in the degradation character of epoxy resin insulations at normal temperature to estimate their life. Thus the aging tests on epoxy insulations were accomplished, and then resistive leakage current on their insulations kept in a glass state at 90 and 80°C was measured by the method canceling capacitive current which was applied to degradation estimation of ZnO varistors. Results of reduced resistive leakage current were led to evaporation and migration of hydrogen ions in epoxy insulations, which are compared between new ones and used ones and applied to estimation of aging degradation in this paper.

  18. Tests of the Extension and Deadbolt Models of Integrin Activation*

    2007-01-01

    Despite extensive evidence that integrin conformational changes between bent and extended conformations regulate affinity for ligands, an alternative hypothesis has been proposed in which a “deadbolt” can regulate affinity for ligand in the absence of extension. Here, we tested both the deadbolt and the extension models. According to the deadbolt model, a hairpin loop in the β3 tail domain could act as a deadbolt to restrain the displacement of the β3 I domain β6-α7 loop and maintain integrin in the low affinity state. We found that mutating or deleting the β3 tail domain loop has no effect on ligand binding by either αIIbβ3 or αVβ3 integrins. In contrast, we found that mutations that lock integrins in the bent conformation with disulfide bonds resist inside-out activation induced by cytoplasmic domain mutation. Furthermore, we demonstrated that extension is required for accessibility to fibronectin but not smaller fragments. The data demonstrate that integrin extension is required for ligand binding during integrin inside-out signaling and that the deadbolt does not regulate integrin activation. PMID:17301049

    The Double Shell Tanks (DSTs) play a critical role in the Hanford High-Level Waste Treatment Complex, and therefore activities are underway to protect and better understand these tanks. The DST Life Extension Program is focused on both tank life extension and on evaluation of tank integrity. Tank life extension activities focus on understanding tank failure modes and have produced key chemistry and operations controls to minimize tank corrosion and extend useful tank life. Tank integrity program activities have developed and applied key technologies to evaluate the condition of the tank structure and predict useful tank life. Program results to date indicate that DST useful life can be extended well beyond the original design life and allow the existing tanks to fill a critical function within the Hanford High-Level Waste Treatment Complex. In addition the tank life may now be more reliably predicted, facilitating improved planning for the use and possible future replacement of these tanks.

    Testing forms a critical part of the development process for large-scale software, and there is growing need for automated tools that can read, represent, analyze, and transform the application's source code to help carry out testing tasks. However, the support required to compile applications written in common general purpose languages is generally inaccessible to the testing research community. In this paper, we report on an extensible, open-source compiler infrastructure called ROSE, which is currently in development at Lawrence Livermore National Laboratory. ROSE specifically targets developers who wish to build source-based tools that implement customized analyses and optimizations for large-scale C, C++, and Fortran90 scientific computing applications (on the order of a million lines of code or more). However, much of this infrastructure can also be used to address problems in testing, and ROSE is by design broadly accessible to those without a formal compiler background. This paper details the interactions between testing of applications and the ways in which compiler technology can aid in the understanding of those applications. We emphasize the particular aspects of ROSE, such as support for the general analysis of whole programs, that are particularly well-suited to the testing research community and the scale of the problems that community solves.

  5. Criterion-Related Validity of Sit-and-Reach Tests for Estimating Hamstring and Lumbar Extensibility: a Meta-Analysis.

    The main purpose of the present meta-analysis was to examine the scientific literature on the criterion-related validity of sit-and-reach tests for estimating hamstring and lumbar extensibility. For this purpose relevant studies were searched from seven electronic databases dated up through December 2012. Primary outcomes of criterion-related validity were Pearson´s zero-order correlation coefficients (r) between sit-and-reach tests and hamstrings and/or lumbar extensibility criterion measures. Then, from the included studies, the Hunter- Schmidt´s psychometric meta-analysis approach was conducted to estimate population criterion- related validity of sit-and-reach tests. Firstly, the corrected correlation mean (rp), unaffected by statistical artefacts (i.e., sampling error and measurement error), was calculated separately for each sit-and-reach test. Subsequently, the three potential moderator variables (sex of participants, age of participants, and level of hamstring extensibility) were examined by a partially hierarchical analysis. Of the 34 studies included in the present meta-analysis, 99 correlations values across eight sit-and-reach tests and 51 across seven sit-and-reach tests were retrieved for hamstring and lumbar extensibility, respectively. The overall results showed that all sit-and-reach tests had a moderate mean criterion-related validity for estimating hamstring extensibility (rp = 0.46-0.67), but they had a low mean for estimating lumbar extensibility (rp = 0. 16-0.35). Generally, females, adults and participants with high levels of hamstring extensibility tended to have greater mean values of criterion-related validity for estimating hamstring extensibility. When the use of angular tests is limited such as in a school setting or in large scale studies, scientists and practitioners could use the sit-and-reach tests as a useful alternative for hamstring extensibility estimation, but not for estimating lumbar extensibility.

    The analysis of mutations that are associated with the occurrence of drug resistance is important for monitoring the antiretroviral therapy of patients infected with human immunodeficiency virus (HIV). Here, we describe the establishment and successful application of Arrayed Primer Extension (APEX) for genotypic resistance testing in HIV as a rapid and economical alternative to standard sequencing. The assay is based on an array of oligonucleotide primers that are immobilised via their 5′-ends. Upon hybridisation of template DNA, a primer extension reaction is performed in the presence of the four dideoxynucleotides, each labelled with a distinct fluorophore. The inserted label immediately indicates the sequence at the respective position. Any mutation changes the colour pattern. We designed a microarray for the analysis of 26 and 33 codons in the HIV protease and reverse transcriptase, respectively, which are of special interest with respect to drug resistance. The enormous genome variability of HIV represents a big challenge for genotypic resistance tests, which include a hybridisation step, both in terms of specificity and probe numbers. The use of degenerated oligonucleotides resulted in a significant reduction in the number of primers needed. For validation, DNA of 94 and 48 patients that exhibited resistance to inhibitors of HIV protease and reverse transcriptase, respectively, were analysed. The validation included HIV subtype B, prevalent in industrialised countries, as well as non-subtype B samples that are more common elsewhere.

  8. Testing and extension of a sea lamprey feeding model

    Cochran, Philip A.; Swink, William D.; Kinziger, Andrew P.

    1999-01-01

    A previous model of feeding by sea lamprey Petromyzon marinus predicted energy intake and growth by lampreys as a function of lamprey size, host size, and duration of feeding attachments, but it was applicable only to lampreys feeding at 10°C and it was tested against only a single small data set of limited scope. We extended the model to other temperatures and tested it against an extensive data set (more than 700 feeding bouts) accumulated during experiments with captive sea lampreys. Model predictions of instantaneous growth were highly correlated with observed growth, and a partitioning of mean squared error between model predictions and observed results showed that 88.5% of the variance was due to random variation rather than to systematic errors. However, deviations between observed and predicted values varied substantially, especially for short feeding bouts. Predicted and observed growth trajectories of individual lampreys during multiple feeding bouts during the summer tended to correspond closely, but predicted growth was generally much higher than observed growth late in the year. This suggests the possibility that large overwintering lampreys reduce their feeding rates while attached to hosts. Seasonal or size-related shifts in the fate of consumed energy may provide an alternative explanation. The lamprey feeding model offers great flexibility in assessing growth of captive lampreys within various experimental protocols (e.g., different host species or thermal regimes) because it controls for individual differences in feeding history.

    Objective: To investigate the effect of Meek skin grafting on patients with extensive deep burn at different age groups. Methods: Eighty-four patients with extensive deep burns conforming to the study criteria were hospitalized in our unit from April 2011 to April 2015. Patients were divided into children group (C, with age less than 12 years old), young and middle-aged group (YM, with age more than 18 years and less than 50 years old), and old age group (O, with age more than 55 years old) according to age, with 28 patients in each group. All patients received Meek skin grafting treatment. The use of autologous skin area, operation time, wound healing time, and hospitalization time were recorded. The survival rate of skin graft on post operation day 7, complete wound healing rate in post treatment week 2, and the mortality were calculated. Data were processed with one-way analysis of variance, t test, and χ(2) test. Results: The use of autologous skin area of patients in group C was (5.1±1.0)% total body surface area (TBSA), significantly less than (8.3±1.0)%TBSA and (8.3±1.4)%TBSA in groups YM and O, respectively (with t values 32.900 and 52.624, respectively, P values below 0.05). The operation time, wound healing time, and hospitalization time of patients in group C were (1.368±0.562) h, (9.6±0.6) and (32±11) d, significantly shorter than those in group YM [(3.235±0.011) h, (16.9±2.6) and (48±12) d, respectively] and group O [(3.692±0.481) h, (17.3±2.6) and (46±13) d, respectively, with t values from 4.350 to 21.160, P values below 0.05]. The survival rate of skin graft of patients on post operation day 7 in group C was (92±15)%, significantly higher than (81±10)% and (72±12)% in groups YM and O, respectively (with t values 5.509 and 3.229, respectively, P values below 0.05). The above indexes in groups YM and O were similar (with t values from 0.576 to 22.958, P values above 0.05). Complete wound healing rate in post treatment week 2 and the

    It is often assumed that there is broad public support for strong life extension research (i.e. research aimed at the dramatic extension of human life beyond the current maximum), and that there would be a near universal interest in using any life extending technologies that this research may produce. In this paper we report the opinions of researchers in ageing on the controversial promise of life extension, and compare these views. This paper describes the professional attitudes, personal interest and concerns expressed by Australian and international researchers in ageing (n = 14) as expressed during semi-structured, in-depth interviews. Researchers held varying opinions about the possibility of significantly extending human life. Some saw a limit to the extension of human life, while others did not. Some felt that research into the fundamental ageing process was a priority; others did not. Researchers tended to weigh up the potential risks and benefits of life extension with most expressing a personal interest in life extension that was contingent on the technology providing a good quality of life. Some participants were not interested in the prospect of life extension for personal reasons, because they felt the potential risks outweighed the potential benefits, or because life extension raised issues of justice and equity.

    The modified Thomas test was developed to assess the presence of hip flexion contracture and to measure hip extensibility. Despite its widespread use, to the authors' knowledge, its criterion reference validity has not yet been investigated. The purpose of this study was to assess the criterion reference validity of the modified Thomas test for measuring peak hip extension angle and hip extension deficits, as defined by the hip not being able to extend to 0º, or neutral. Twenty-nine healthy college students (age = 22.00 ± 3.80 years; height = 1.71 ± 0.09 m; body mass = 70.00 ± 15.60 kg) were recruited for this study. Bland-Altman plots revealed poor validity for the modified Thomas test's ability to measure hip extension, which could not be explained by differences in hip flexion ability alone. The modified Thomas test displayed a sensitivity of 31.82% (95% CI [13.86-54.87]) and a specificity of 57.14% (95% CI [18.41-90.10]) for testing hip extension deficits. It appears, however, that by controlling pelvic tilt, much of this variance can be accounted for (r = 0.98). When pelvic tilt is not controlled, the modified Thomas test displays poor criterion reference validity and, as per previous studies, poor reliability. However, when pelvic tilt is controlled, the modified Thomas test appears to be a valid test for evaluating peak hip extension angle.

    A new test assembly algorithm based on a Monte Carlo random search is presented in this article. A major advantage of the Monte Carlo test assembly over other approaches (integer programming or enumerative heuristics) is that it performs a uniform sampling from the item pool, which provides every feasible item combination (test) with an equal…

    The modified Thomas test was developed to assess the presence of hip flexion contracture and to measure hip extensibility. Despite its widespread use, to the authors’ knowledge, its criterion reference validity has not yet been investigated. The purpose of this study was to assess the criterion reference validity of the modified Thomas test for measuring peak hip extension angle and hip extension deficits, as defined by the hip not being able to extend to 0º, or neutral. Twenty-nine healthy college students (age = 22.00 ± 3.80 years; height = 1.71 ± 0.09 m; body mass = 70.00 ± 15.60 kg) were recruited for this study. Bland–Altman plots revealed poor validity for the modified Thomas test’s ability to measure hip extension, which could not be explained by differences in hip flexion ability alone. The modified Thomas test displayed a sensitivity of 31.82% (95% CI [13.86–54.87]) and a specificity of 57.14% (95% CI [18.41–90.10]) for testing hip extension deficits. It appears, however, that by controlling pelvic tilt, much of this variance can be accounted for (r = 0.98). When pelvic tilt is not controlled, the modified Thomas test displays poor criterion reference validity and, as per previous studies, poor reliability. However, when pelvic tilt is controlled, the modified Thomas test appears to be a valid test for evaluating peak hip extension angle. PMID:27602291

  18. Extensive Test of an SU(3)-based Partial Dynamical Symmetry

    NASA Astrophysics Data System (ADS)

    Casten, R. F.

    2014-09-01

    The concept of symmetries pervades much of our understanding of nature. In nuclear structure, the IBA embodies a framework with three dynamical symmetries U(5), O(6) and SU(3). Of course, most nuclei break these symmetries. Leviatan has discussed a concept of Partial Dynamical Symmetry (PDS) in which the states of the ground and gamma bands, only, are exactly described by SU(3) while all others are not. With an E2 operator which is not a generator of SU(3), this PDS gives a parameter-free description of γ to ground band relative B(E2) values in 168Er that is virtually identical to the best collective model (IBA) calculations with 2-3 parameters. We have carried out the first extensive study of this PDS, in 47 rare earth nuclei. Overall, the PDS works very well, and the deviations from the data are usually understandable in terms of specific kinds of mixing.

  19. Using geodetic VLBI to test Standard-Model Extension

    2016-04-01

    The modeling of the relativistic delay in geodetic techniques is primordial to get accurate geodetic products. And geodetic techniques can also be used to measure the relativistic delay and get constraints on parameters describing the relativity theory. The effective field theory framework called the Standard-Model Extension (SME) has been developed in order to systematically parametrize hypothetical violations of Lorentz symmetry (in the Standard Model and in the gravitational sector). In terms of light deflexion by a massive body like the Sun, one can expect a dependence in the elongation angle different from GR. In this communication, we use geodetic VLBI observations of quasars made in the frame of the permanent geodetic VLBI monitoring program to constrain the first SME coefficient. Our results do not show any deviation from GR and they improve current constraints on both GR and SME parameters.

    Objective. Investigate time-related age differences in cognitive functioning without influences of prior test experience. Methods. Cognitive scores were compared in different individuals from the same birth years who were tested in different years, when they were at different ages. These types of quasi-longitudinal comparisons were carried out on data from three large projects: the Seattle Longitudinal Study [Schaie, K. W. (2013). Developmental influences on adult intelligence: The Seattle Longitudinal Study (2nd ed.). New York, NY: Oxford University Press], the Betula Project [Ronnlund, M., & Nilsson, L-G. (2008). The magnitude, generality, and determinants of Flynn effects on forms of declarative memory and visuospatial ability: Time-sequential analyses of data from a Swedish cohort study. Intelligence, 36, 192–209], and the Virginia Cognitive Aging Project (this study). Results. In each data set, the results revealed that the estimates of cognitive change with no prior test experience closely resembled the estimates of age relations based on cross-sectional comparisons. Furthermore, longitudinal comparisons revealed positive changes at young ages that gradually became more negative with increased age, whereas all of the estimates of change without prior test experience were negative except those for measures of vocabulary. Discussion. The current results suggest that retest effects can distort the mean age trends in longitudinal comparisons that are not adjusted for experience. Furthermore, the findings can be considered robust because the patterns were similar across three data sets involving different samples of participants and cognitive tests, and across different methods of controlling experience effects in the new data set.

    This study confirms the clinical value of investigating the "iliacus complex" during evaluations of the low back. A new "iliacus test" isolates this iliacus complex component of limited hip extension. Designed for a single joint, the test isolates motion across the hip joint. Study results include the following: (1) in a comparison with the clinical standard, the Thomas test, data show that the two tests are significantly different in an asymptomatic population between the ages of 18 and 35 years; (2) with the exception of the standard Thomas test, the data show no statistical differences in range of motion when comparing the left side with the right side; (3) examiner-added, end-range pressure for assessment of range of motion when compared with the standard gravity-dependent end range of motion used in the Thomas test yields valuable new information; and (4) data provide a basis for population norms for each test--Thomas and iliacus--in gravity-dependent and examiner-produced tissue-feel end ranges.

    Progress toward understanding the underlying mechanisms of pelvic organ prolapse (POP) is limited, in part, due to a lack of information on the biomechanical properties and microstructural composition of the vaginal wall. Compromised vaginal wall integrity is thought to contribute to pelvic floor disorders; however, normal structure-function relationships within the vaginal wall are not fully understood. In addition to the information produced from uniaxial testing, biaxial extension-inflation tests performed over a range of physiological values could provide additional insights into vaginal wall mechanical behavior (i.e., axial coupling and anisotropy), while preserving in vivo tissue geometry. Thus, we present experimental methods of assessing murine vaginal wall biaxial mechanical properties using extension-inflation protocols. Geometrically intact vaginal samples taken from 16 female C57BL/6 mice underwent pressure-diameter and force-length preconditioning and testing within a pressure-myograph device. A bilinear curve fit was applied to the local stress-stretch data to quantify the transition stress and stretch as well as the toe- and linear-region moduli. The murine vaginal wall demonstrated a nonlinear response resembling that of other soft tissues, and evaluation of bilinear curve fits suggests that the vagina exhibits pseudoelasticity, axial coupling, and anisotropy. The protocols developed herein permit quantification of biaxial tissue properties. These methods can be utilized in future studies in order to assess evolving structure-function relationships with respect to aging, the onset of prolapse, and response to potential clinical interventions.

    2016-01-01

    The effects of age in usability testing were examined in an experiment. Sixty users from two age groups (M = 23.0 yrs, M = 58.1 yrs) operated two technical devices (keyboard-based and touchscreen-based smartphones). In addition to various performance measures (e.g. task completion time, task completion rate), several subjective measures were taken (e.g. perceived usability, affect, and workload). The results showed better performance scores for younger adults than older adults for task completion time. For older adult users there was a mismatch between usability ratings and task completion time but not between usability ratings and task completion rate. Age-related differences in the importance of speed and accuracy in task completion point to the need to consider more strongly the factor user age in usability research and practice.

    As a continuation of earlier wire aging investigations, additional candidates for wire chamber gas and wire have been tested. These include the gases: argon/ethane, HRS gas, dimethyl ether, carbon dioxide/ethane, and carbon tetrafluoride/isobutane. Wires used were: gold- plated tungsten, Stablohm, Nicotin, and Stainless Steel. Measurements were made of the effects upon wire aging of impurities from plumbing materials or contamination from various types of oil. Attempts were made to induce wire aging by adding measured amounts of oxygen and halogen (methyl chloride) with negative results. In this paper, the possible role of electronegativity in the wire aging process is discussed, and measurements of electronegativity are made with several single carbon Freons, using both an electron capture detector and a wire chamber operating with dimethyl ether.

  10. Limiting extensibility constitutive model with distributed fibre orientations and ageing of abdominal aorta.

    PubMed

    2014-10-01

    The abdominal aorta is susceptible to age-related pathological changes (arteriosclerosis, atherosclerosis, aneurysm, and tortuosity). Computational biomechanics and mechanobiology provide models capable of predicting mutual interactions between a changing mechanical environment and patho-physiological processes in ageing. However, a key factor is a constitutive equation which should reflect the internal tissue architecture. Our study investigates three microstructurally-motivated invariant-based hyperelastic anisotropic models suitable for description of the passive mechanical behaviour of the human abdominal aorta at a multiaxial state of stress known from recent literature. The three adopted models have also been supplemented with a newly proposed constitutive model (limiting extensibility with fibre dispersion). All models additively decouple the mechanical response of the isotropic (elastin and smooth muscle cells represented by the neo-Hookean term) and the anisotropic (collagen) parts. Two models use exponential functions to capture large strain stiffening ascribed to the engagement of collagen fibres into the load-bearing process. The other two models are based on the concept of limiting extensibility. Perfect alignment of reinforcing fibres with two preferred directions as well as fibre dispersion are considered. Constitutive models are calibrated to the inflation-extension response adopted from the literature based on the computational model of the residually-stressed thick-walled tube. A correlation analysis of determined material parameters was performed to reveal dependence on the age. The results of the nonlinear regression suggest that limiting fibre extensibility is the concept which is suitable to be used for the constitutive description of the aorta at multiaxial stress states and is highly sensitive to ageing-induced changes in mechanical response.

    A technique has been developed to quantitatively describe macroscopic cracks, both their location and extent, in heterogeneous high explosive and mock materials. By combining such a technique with the deformation field measurement using digital image correlation (DIC), we conduct observation and measurement of the initiation, extension, and coalescence of internal cracks in the compression of Brazilian disk made of pristine and artificially aged PBX 9501 hjgh explosives. Our results conclude quantitatively that aged PBX 9501 is not only weaker but also much more brittle than the pristine one, thus is more susceptible to macroscopic cracking.

    Tactile expertise, resulting from extensive use of hands, has previously been shown to improve tactile perception in blind people and musicians and to be associated with changes in the central processing of tactile information. This study investigated whether expertise, due to precise and deliberate use of the fingers at work, relates to improved tactile perception and whether this expertise interacts with age. A tactile pattern and a frequency discrimination task were conducted while ERPs were measured in experts and nonexperts of two age groups within middle adulthood. Independently of age, accuracy was better in experts than in nonexperts in both tasks. Somatosensory N70 amplitudes were larger with increasing age and for experts than for nonexperts. P100 amplitudes were smaller in experts than in nonexperts in the frequency discrimination task. In the pattern discrimination task, P300 difference wave amplitude was reduced in experts and late middle-aged adults. In the frequency discrimination task, P300 was more equally distributed in late middle-aged adults. We conclude that extensive, dexterous manual work leads to acquisition of tactile expertise and that this expertise might delay, but not counteract, age effects on tactile perception. Comparable neurophysiological changes induced by age and expertise presumably have different underlying mechanisms. Enlarged somatosensory N70 amplitudes might result from reduced inhibition in older adults but from enhanced, specific excitability of the somatosensory cortex in experts. Regarding P300, smaller amplitudes might indicate fewer available resources in older adults and, by contrast, a reduced need to engage as much cognitive effort to the task in experts.

    The cardiac troponin I (cTnI) isoform contains a unique N-terminal extension that functions to modulate activation of cardiac myofilaments. During cardiac remodeling restricted proteolysis of cTnI removes this cardiac specific N-terminal modulatory extension to alter myofilament regulation. We have demonstrated expression of the N-terminal-deleted cTnI (cTnI-ND) in the heart decreased the development of the cardiomyopathy like phenotype in a β-adrenergic-deficient transgenic mouse model. To investigate the potential beneficial effects of cTnI-ND on the development of naturally occurring cardiac dysfunction, we measured the hemodynamic and biochemical effects of cTnI-ND transgenic expression in the aged heart. Echocardiographic measurements demonstrate cTnI-ND transgenic mice exhibit increased systolic and diastolic functions at 16 months of age compared with age-matched controls. This improvement likely results from decreased Ca2+ sensitivity and increased cross-bridge kinetics as observed in skinned papillary bundles from young transgenic mice prior to the effects of aging. Hearts of cTnI-ND transgenic mice further exhibited decreased β myosin heavy chain expression compared to age matched non-transgenic mice as well as altered cTnI phosphorylation. Finally, we demonstrated cTnI-ND expressed in the heart is not phosphorylated indicating the cTnI N-terminal is necessary for the higher level phosphorylation of cTnI. Taken together, our data suggest the regulated proteolysis of cTnI during cardiac stress to remove the unique cardiac N-terminal extension functions to improve cardiac contractility at the myofilament level and improve overall cardiac function.

    Nuclear material inventories are increasingly being transferred to interim storage locations where they may reside for extended periods of time. Use of a shipping package to store nuclear materials after the transfer has become more common for a variety of reasons. Shipping packages are robust and have a qualified pedigree for performance in normal operation and accident conditions but are only certified over an approved transportation window. The continued use of shipping packages to contain nuclear material during interim storage will result in reduced overall costs and reduced exposure to workers. However, the shipping package materials of construction must maintain integrity as specified by the safety basis of the storage facility throughout the storage period, which is typically well beyond the certified transportation window. In many ways, the certification processes required for interim storage of nuclear materials in shipping packages is similar to life extension programs required for dry cask storage systems for commercial nuclear fuels. The storage of spent nuclear fuel in dry cask storage systems is federally-regulated, and over 1500 individual dry casks have been in successful service up to 20 years in the US. The uncertainty in final disposition will likely require extended storage of this fuel well beyond initial license periods and perhaps multiple re-licenses may be needed. Thus, both the shipping packages and the dry cask storage systems require materials integrity assessments and assurance of continued satisfactory materials performance over times not considered in the original evaluation processes. Test programs for the shipping packages have been established to obtain aging data on materials of construction to demonstrate continued system integrity. The collective data may be coupled with similar data for the dry cask storage systems and used to support extending the service life of shipping packages in both transportation and storage.

    2006-01-01

    A four-list version of a release from proactive interference paradigm was used to assess the degree to which older and younger adults tested at optimal and nonoptimal times of day are vulnerable to interference effects in memory, effects that may increase at nonoptimal times. Morning type older adults and Evening type younger adults were tested either early in the morning or late in the afternoon. Standard buildup and release effects were shown for all age groups except for older adults tested in the afternoon; they failed to show release. Recall and intrusion data suggested that older adults are more vulnerable to proactive interference than younger adults and that for older adults at least, interference effects are heightened at nonoptimal times of day. The data are discussed in terms of an inhibitory model of control over the contents of working memory (Hasher, Zacks, & May, 1999). PMID:12271750

    Early versions of uncemented femoral total hip stems were often associated with thigh pain thought to be due to micromotion between the implant and bone in the distal uncoated regions. An extensively coated stem was introduced in 1992 to reduce that risk. We therefore asked whether second-generation extensively porous-coated cementless femoral stems in patients younger than 50 years of age would (1) be durable in terms of revisions; (2) provide high functional scores and reduce thigh pain; and (3) show radiographic signs of durability, including a reduction in stress shielding. We prospectively followed all 100 patients (115 hips) age 50 and younger treated with primary cementless total hip arthroplasties using a second-generation extensively porous-coated femoral stem between June 1994 and December 1999. The average age was 39.6 years (range, 17-50 years). The stems were mated to cementless acetabular components. Ninety patients were followed for a minimum of 5 years (mean, 8.6 years; range, 5-10 years). One stem was revised after a periprosthetic fracture. None were revised for loosening and all stems demonstrated bony ingrowth at last followup. No acetabular shell was revised for loosening and none was radiographically loose. Six acetabular liners were revised for wear (three each were 22-mm and 26-mm heads). This second-generation extensively porous-coated stem was durable at 5- to 10-year followup in this young active population. Level IV, therapeutic study.

  17. Degradation mechanisms and accelerated aging test design

    1985-01-01

    The fundamental mechanisms underlying the chemical degradation of polymers can change as a function of environmental stress level. When this occurs, it greatly complicates any attempt to use accelerated tests for predicting long-term material degradation behaviors. Understanding how degradation mechanisms can change at different stress levels facilitates both the design and the interpretation of aging tests. Oxidative degradation is a predominant mechanism for many polymers exposed to a variety of different environments in the presence of air, and there are two mechanistic considerations which are widely applicable to material oxidation. One involves a physical process, oxygen diffusion, as a rate-limiting step. This mechanism can predominate at high stress levels. The second is a chemical process, the time-dependent decomposition of peroxide species. This leads to chain branching and can become a rate-controlling factor at lower stress levels involving time-scales applicable to use environments. The authors describe methods for identifying the operation of these mechanisms and illustrate the dramatic influence they can have on the degradation behaviors of a number of polymer types. Several commonly used approaches to accelerated aging tests are discussed in light of the behaviors which result from changes in degradation mechanisms. 9 references, 4 figures.

  1. Aging of concrete components and its significance relative to life extension of nuclear power plants

    1987-01-01

    Nuclear power currently supplies about 16% of the US electricity requirements, with the percentage expected to rise to 20% by 1990. Despite the increasing role of nuclear power in energy production, cessation of orders for new nuclear plants in combination with expiration of operating licenses for several plants in the next 15 to 20 years results in a potential loss of electrical generating capacity of 50 to 60 gigawatts during the time period 2005 to 2020. A potential timely and cost-effective solution to the problem of meeting future energy demand is available through extension of the service life of existing nuclear plants. Any consideration of plant life extension, however, must consider the concrete components in these plants, since they play a vital safety role. Under the USNRC Nuclear Plant Aging Research (NPAR) Program, a study was conducted to review operating experience and to provide background that will lead to subsequent development of a methodology for assessing and predicting the effects of aging on the performance of concrete-based structures. The approach followed was in conformance with the NPAR strategy.

  2. Dark Ages Radio Explorer Instrument Verification Program: Antenna Test Results

    Observations of the HI 21 cm transition line promises to be an important probe into the cosmic Dark Ages and Epoch of Reionization. The Dark Ages Radio Explorer (DARE) is designed to measure the sky-averaged 21-cm signal from this cosmic age using a single radiometer operating between 40-120 MHz (redshifts z=11-35). DARE will orbit the Moon for a mission lifetime of ≤ 3 years and take data above the lunar far side, where it is shielded from the Earth's intense interference. The science objectives of DARE include formation of first stars, first accreting black holes, beginning of reionization and end of the Dark Ages. The science instrument is composed of a three-element radiometer, including electrically-short, tapered, bi-conical dipole antennas, a receiver, and a digital spectrometer. Although the TRL (Technology Readiness Level) of the individual components of DARE instrument is high, the overall instrument TRL is low. One of the main aim of the entire DARE team is to advance the instrument TRL. In this work we mainly focus on the development work for DARE Antenna. We will present the initial test results of a prototype DARE antenna, fabricated in NRAO. Some CST simulations using the actual DARE experiment set up have also been performed. In future, we plan to perform extensive tests to characterize the beam pattern and spectral response of the prototype DARE instrument design. In order to utilize the anechoic chamber available at NRAO, we will use a half-scale version of the DARE antenna (120-200 MHz). The full-scale version of the DARE antenna (40-120 MHz) along with the final version of the DARE receiver will be used for outdoor tests in the low-RFI environment of Western Australia. We will also present the initial software development for analyzing the test results from the prototype DARE antenna and receiver.

  3. Tests of local Lorentz invariance violation of gravity in the standard model extension with pulsars.

    The standard model extension is an effective field theory introducing all possible Lorentz-violating (LV) operators to the standard model and general relativity (GR). In the pure-gravity sector of minimal standard model extension, nine coefficients describe dominant observable deviations from GR. We systematically implemented 27 tests from 13 pulsar systems to tightly constrain eight linear combinations of these coefficients with extensive Monte Carlo simulations. It constitutes the first detailed and systematic test of the pure-gravity sector of minimal standard model extension with the state-of-the-art pulsar observations. No deviation from GR was detected. The limits of LV coefficients are expressed in the canonical Sun-centered celestial-equatorial frame for the convenience of further studies. They are all improved by significant factors of tens to hundreds with existing ones. As a consequence, Einstein's equivalence principle is verified substantially further by pulsar experiments in terms of local Lorentz invariance in gravity.

    2017-01-01

    Carbon-carbon (C-C) composite nozzle extensions are of interest for use on a variety of launch vehicle upper stage engines and in-space propulsion systems. The C-C nozzle extension technology and test capabilities being developed are intended to support National Aeronautics and Space Administration (NASA) and Department of Defense (DOD) requirements, as well as those of the broader Commercial Space industry. For NASA, C-C nozzle extension technology development primarily supports the NASA Space Launch System (SLS) and NASA's Commercial Space partners. Marshall Space Flight Center (MSFC) efforts are aimed at both (a) further developing the technology and databases needed to enable the use of composite nozzle extensions on cryogenic upper stage engines, and (b) developing and demonstrating low-cost capabilities for testing and qualifying composite nozzle extensions. Recent, on-going, and potential future work supporting NASA, DOD, and Commercial Space needs will be discussed. Information to be presented will include (a) recent and on-going mechanical, thermal, and hot-fire testing, as well as (b) potential future efforts to further develop and qualify domestic C-C nozzle extension solutions for the various upper stage engines under development.

  8. Innovating aging: promises and pitfalls on the road to life extension

    One of the main benefits from the dramatic technological progress over the last two centuries is the enormous increase in human life expectancy, which has now reached record highs. After conquering most childhood diseases and a fair fraction of the diseases that plague adulthood, medical technology is now mainly pre-occupied by age-related disorders. Further progress is dependent on circumventing the traditional medical focus on individual diseases and instead targeting aging as a whole as the ultimate cause of the health problems that affect humankind at old age. In principle, a major effort to control the gradual accumulation of molecular and cellular damage – considered by many as the ultimate cause of intrinsic aging – may rapidly lead to interventions for regenerating aged and worn-out tissues and organs. While considered impossible by many, there really is no reason to reject this as scientifically implausible. However, as we discuss, it is not only scientific progress that is currently a limiting factor, but societal factors that hinder and may ultimately prevent further progress in testing and adopting the many possible interventions to cure aging.

  12. Reliability of Goniometric and Trigonometric Techniques for Measuring Hip-Extension Range of Motion Using the Modified Thomas Test

    PubMed Central

    Wakefield, C. Brent; Halls, Amanda; Difilippo, Nicole; Cottrell, G. Trevor

    2015-01-01

    Context: Goniometric assessment of hip-extension range of motion is a standard practice in clinical rehabilitation settings. A weakness of goniometric measures is that small errors in landmarking may result in substantial measurement error. A less commonly used protocol for measuring hip range of motion involves applying trigonometric principles to the length and vertical displacement of the upper part of the lower extremity to determine hip angle; however, the reliability of this measure has never been assessed using the modified Thomas test. Objective: To compare the intrarater and interrater reliability of goniometric (GON) and trigonometric (TRIG) techniques for assessing hip-extension range of motion during the modified Thomas test. Design: Controlled laboratory study. Setting: Institutional athletic therapy facility. Patients or Other Participants: A total of 22 individuals (12 men, 10 women; age range, 18–36 years) with no pathologic knee or back conditions. Main Outcome Measure(s): Hip-extension range of motion of each participant during a modified Thomas test was assessed by 2 examiners with both GON and TRIG techniques in a randomly selected order on 2 separate days. Results: The intraclass correlation coefficient (ICC) revealed that the reliability of the GON technique was low for both the intrarater (ICC = 0.51, 0.54) and interrater (ICC = 0.30, 0.65) comparisons, but the reliability of the TRIG technique was high for both intrarater (ICC = 0.90, 0.95) and interrater (ICC = 0.91, 0.94) comparisons. Single-factorial repeated-measures analyses of variance revealed no mean differences in scoring within or between examiners for either measurement protocol, whereas a difference was observed when comparing the TRIG and GON tests due to the differences in procedures used to identify landmarks. Conclusions: Using the TRIG technique to measure hip-extension range of motion during the modified Thomas test results in superior intrarater and interrater

    2016-07-01

    We investigated 7- to 10-year-old children's productive extension of semantic memory through self-generation of new factual knowledge derived through integration of separate yet related facts learned through instruction or through reading. In Experiment 1, an experimenter read the to-be-integrated facts. Children successfully learned and integrated the information and used it to further extend their semantic knowledge, as evidenced by high levels of correct responses in open-ended and forced-choice testing. In Experiment 2, on half of the trials, the to-be-integrated facts were read by an experimenter (as in Experiment 1) and on half of the trials, children read the facts themselves. Self-generation performance was high in both conditions (experimenter- and self-read); in both conditions, self-generation of new semantic knowledge was related to an independent measure of children's reading comprehension. In Experiment 3, the way children deployed cognitive resources during reading was predictive of their subsequent recall of newly learned information derived through integration. These findings indicate self-generation of new semantic knowledge through integration in school-age children as well as relations between this productive means of extension of semantic memory and cognitive processes engaged during reading.

  16. Thermoluminescence dating of sediments: a re-extension of age range for loess

    1985-01-01

    Thermoluminescence (TL) dating of wind blown minerals provides a technique whereby non-carbonaceous sediments could be dated to several hundred thousand years. Two recent reports, however, indicate age underestimates on feldspar in some European loesses older than 50 ka, the effect increasing in severity with age. Suggested causes include decay of luminescence centers, or does dependent sensitivity changes. Data presented in this paper do not support these limitations or explanations. TL provides 3 separate techniques of dating sediments, which, when used together, prove to be efficient internal cross checks for mineralogical anomalies or inconsistencies created by any of the individual methods. In the authors studies each sample was dated by all 3 methods whereas the Europeans analyses employed only the Regeneration technique. This work presents results from loess sections in Mississippi, Illinois and Alaska. These show excellent internal consistency, and consistency with both independent dating methods and stratigraphy, with 2 exceptions. Both exceptions were by the Regen technique giving age underestimates up to 30%. The underestimates were found to be caused by a change in mineral sensitivity resulting from the Regen requirements of strong laboratory light-bleaching followed by irradiations. A simple method to test and correct for this condition is presented. TL thus appears to remain a powerful and increasingly flexible method of sediment dating.

    Multiple-baseline designs are an extension of the basic single-case AB phase designs, in which several of those AB designs are implemented simultaneously to different persons, behaviors, or settings, and the intervention is introduced in a staggered way to the different units. These designs are well-suited for research in the behavioral sciences. We discuss the advantages and limitations for valid inferences, and suggest a statistical technique--randomization tests--for use with multiple-baseline data, to complement visual analysis. In addition, we provide an extension of our SCRT-R package (which already contained means for conducting randomization tests on single-case phase and alternation designs), for multiple-baseline AB data.

    2011-02-01

    The purpose of the present study was to investigate the statistical properties of two extensions of the Levin-Wampold (1999) single-case simultaneous start-point model's comparative effectiveness randomization test. The two extensions were (a) adapting the test to situations where there are more than two different intervention conditions and (b) examining the test's performance in classroom-based intervention situations, where the number of time periods (and associated outcome observations) is much smaller than in the contexts for which the test was originally developed. Various Monte Carlo sampling situations were investigated, including from one to five participant blocks per condition and differing numbers of time periods, potential intervention start points, degrees of within-phase autocorrelation, and effect sizes. For all situations, it was found that the Type I error probability of the randomization test was maintained at an acceptable level. With a few notable exceptions, respectable power was observed only in situations where the numbers of observations and potential intervention start points were relatively large, effect sizes were large, and the degree of within-phase autocorrelation was relatively low. It was concluded that the comparative effectiveness randomization test, with its desirable internal validity and statistical-conclusion validity features, is a versatile analytic tool that can be incorporated into a variety of single-case school psychology intervention research situations.

  1. Cybernetic principles of aging and rejuvenation: the buffering- challenging strategy for life extension.

    PubMed

    Heylighen, Francis

    2014-01-01

    Aging is analyzed as the spontaneous loss of adaptivity and increase in fragility that characterizes dynamic systems. Cybernetics defines the general regulatory mechanisms that a system can use to prevent or repair the damage produced by disturbances. According to the law of requisite variety, disturbances can be held in check by maximizing buffering capacity, range of compensatory actions, and knowledge about which action to apply to which disturbance. This suggests a general strategy for rejuvenating the organism by increasing its capabilities of adaptation. Buffering can be optimized by providing sufficient rest together with plenty of nutrients: amino acids, antioxidants, methyl donors, vitamins, minerals, etc. Knowledge and the range of action can be extended by subjecting the organism to an as large as possible variety of challenges. These challenges are ideally brief so as not to deplete resources and produce irreversible damage. However, they should be sufficiently intense and unpredictable to induce an overshoot in the mobilization of resources for damage repair, and to stimulate the organism to build stronger capabilities for tackling future challenges. This allows them to override the trade-offs and limitations that evolution has built into the organism's repair processes in order to conserve potentially scarce resources. Such acute, "hormetic" stressors strengthen the organism in part via the "order from noise" mechanism that destroys dysfunctional structures by subjecting them to strong, random variations. They include heat and cold, physical exertion, exposure, stretching, vibration, fasting, food toxins, micro-organisms, environmental enrichment and psychological challenges. The proposed buffering-challenging strategy may be able to extend life indefinitely, by forcing a periodic rebuilding and extension of capabilities, while using the Internet as an endless source of new knowledge about how to deal with disturbances.

  2. Changes in Support Networks in Late Middle Age: The Extension of Gender and Educational Differences

    2015-01-01

    Objectives. This paper tests whether differences by gender and by educational attainment in contact with friends and family and in support expected from friends and family narrow or widen in late middle age. Methods. The data are drawn from about 4,800 members of the Wisconsin Longitudinal Survey who answered questions about their frequency of contact with social ties and expectations of 3 kinds of help in both 1993, when they were in their early 50s, and again in 2004. Results. Using lagged dependent variable models, we find that between their 50s and 60s women’s network advantages over men and college graduates’ network advantages over high school graduates in frequency of social contact widened. The same was roughly true as well for expectations of social support, although here the divergences depended partly on the type of the support: Women gained relative to men in “talk” support and in help from nonkin if ill, but lost ground in financial support. The college-educated gained ground in all sorts of support from nonkin. Discussion. These results reinforce concern that late middle age is a period when men and the less educated become yet more disadvantaged in social support, making attention to connectedness yet more critical.

    The field of biogerontology has made great strides towards understanding the biological processes underlying aging, and the time is ripe to look towards applying this knowledge to the pursuit of aging interventions. Identification of safe, inexpensive, and non-invasive interventions that slow the aging process and promote healthy aging could have a significant impact on quality of life and health care expenditures for the aged. While there is a plethora of supplements and interventions on the market that purport to slow aging, the evidence to validate such claims is generally lacking. Here we describe the development of an aging interventions testing program funded by the National Institute on Aging (NIA) to test candidate interventions in a model system. The development of this program highlights the challenges of long-term intervention studies and provides approaches to cope with the stringent requirements of a multi-site testing program.

    Abstract Introduction: Achieving the UNAIDS goals of 90–90-90 will require more than doubling the number of people accessing HIV care in Uganda. Community-based programmes for entry into HIV care are effective strategies to expand access to HIV care, but few programmes have been evaluated with a particular focus on scale-up. Methods: Integrated Community Based Initiatives, a Uganda-based non-governmental organization, designed and implemented a programme of community-based HIV counselling and testing and facilitated linkage to care utilizing community health extension workers (CHEWs) in rural Sheema District, Uganda. CHEWs performed programme activities during 1 October 2015 through 31 March 2016. Outcomes for this evaluation were (1) the number of people tested for HIV, and (2) the proportion of those testing positive who were seen at an ART clinic within three months of their positive test, and (3) the cost of the programme per person newly diagnosed with HIV. Microcosting methods were used to calculate the programme costs. Program scalability factors were evaluated using a published framework. Results: Sixty-two CHEWs attended a five-day training that introduced the biology of HIV, the conduct of confidential HIV testing, HIV prevention messages, and linkage, referral, and reporting requirements. CHEWs received a $30 monthly stipend and a field testing kit that included a bicycle, field bag, umbrella, gumboots, reporting booklet, pens, and HIV testing materials. Trained CHEWs tested 43,696 persons for HIV infection during the six-month programme period. Nine-hundred seventy-four participants (2.2%) were identified as HIV positive, and 623 participants (64%) were linked to HIV care. An estimated 69% of adult residents received testing as part of this campaign. The programme cost $3.02 per person test, $135.70 per positive person identified, and $212.15 per HIV-positive person linked to care. Conclusions: Lay community health extension workers (CHEWs) can be

    It has been suggested that the accuracy of manual muscle testing is dependent on examiner strength. Our purpose was to relate male and female clinicians' upper extremity strength to their ability to challenge the quadriceps and detect weakness in patients using manual muscle testing. Quadriceps muscles of seven men and 12 women with postpoliomyelitis were tested manually by a male and female clinician while forces were recorded with a hand-held dynamometer. Patients' maximal isometric knee extension force was recorded with a Lido dynamometer and clinicians' maximal vertical push force was recorded with the hand-held dynamometer. Manual muscle testing forces, patient maximum quadriceps forces, and examiner push forces were compared with repeated measures analysis of variance. Female examiners' maximal vertical push force (235.7 +/- 54.3 N) was not significantly different from either female or male patients' maximal quadriceps force (166.8 +/- 66.7 N and 341.6 +/- 123.7 N) but was only 60% and 40% of the isometric knee extension forces generated by a group of normal women and men. Male examiners were significantly stronger (357.0 +/- 93.4 N) than the female but not the male patients and produced 90% and 60% of the normal isometric quadriceps forces for women and men. Examiners gave appropriate grades in 30 of 38 tests. Examiner strength limits detection of moderate quadriceps weakness with manual resistance. Most of the muscle test grades, however, were appropriate, given the examiner's upper extremity strength. Clinicians using manual muscle testing should determine their maximal vertical push force and the extent of weakness they can detect.

    2017-03-22

    Recent studies have suggested that Boundary Extension (BE), a scene construction error, may be linked to the function of the hippocampus. In this study, we tested BE in two groups with variations in hippocampal development and disorder: a typically developing sample ranging from preschool to adolescence and individuals with Down syndrome. We assessed BE across three different test modalities: drawing, visual recognition, and a 3D scene boundary reconstruction task. Despite confirmed fluctuations in memory function measured through a neuropsychological assessment, the results showed consistent BE in all groups across test modalities, confirming the near universal nature of BE. These results indicate that BE is an essential function driven by a complex set of processes, that occur even in the face of delayed memory development and hippocampal dysfunction in special populations.

    The Power Extension Package (PEP) is the prime focus of a development program to produce low cost solar cells. The PEP is a 32 kilowatt flexible substrate, retrievable, solar array system for use on the Space Shuttle. Solar cell cost will be reduced by increasing cell area and simplifying cell and coverglass fabrication processes and specifications. The cost goal is to produce cells below $30 per watt. Two and ten ohm-cm silicon cells were investigated. This paper describes a unique radiation damage test and side-by-side comparison of candidate cell types with pre-and post-irradiation airplane calibration of outer space short-circuit current.

    Literature has not shown the minimum time required to recover from muscle fatigue after a prolonged trunk isometric contraction. The purpose of this study was to determine if the lumbar multifidus (LM) and gluteus maximus (GM) muscles would recover from fatigue after three different rest periods following performance of a back extension endurance test. Endurance time and electromyographic (EMG) activity of bilateral LM and GM muscles were collected from 12 healthy adults during a modified Biering-Sørensen test. On three separate visits, each participant performed two modified Biering-Sørensen tests, one before and one after a rest period (3, 6 or 9 min). For each endurance test, endurance time was measured and both mean and median EMG frequency fatigue rates were calculated. The results showed a significantly reduced endurance time and normalized mean frequency fatigue rates on the second modified Biering-Sørensen endurance test regardless of the rest periods (3, 6, and 9 min). This suggests that adequate rest should be considered for fatigue recovery when designing a back and hip endurance exercise program, and that future studies should investigate a rest time longer than 9 minutes for fatigue recovery following a modified Biering-Sørensen endurance test.

On three separate visits, each participant performed two modified Biering-Sørensen tests, one before and one after a rest period (3, 6 or 9 min). For each endurance test, endurance time was measured and both mean and median EMG frequency fatigue rates were calculated. The results showed a significantly reduced endurance time and normalized mean frequency fatigue rates on the second modified Biering-Sørensen endurance test regardless of the rest periods (3, 6, and 9 min). This suggests that adequate rest should be considered for fatigue recovery when designing a back and hip endurance exercise program, and that future studies should investigate a rest time longer than 9 minutes for fatigue recovery following a modified Biering-Sørensen endurance test.

  16. A service life extension (SLEP) approach to operating aging aircraft beyond their original design lives

    NASA Astrophysics Data System (ADS)

    Pentz, Alan Carter

    With today's uncertain funding climate (including sequestration and continuing budget resolutions), decision makers face severe budgetary challenges to maintain dominance through all aspects of the Department of Defense (DoD). To meet war-fighting capabilities, the DoD continues to extend aircraft programs beyond their design service lives by up to ten years, and occasionally much more. The budget requires a new approach to traditional extension strategies (i.e., reuse, reset, and reclamation) for structural hardware. While extending service life without careful controls can present a safety concern, future operations planning does not consider how much risk is present when operating within sound structural principles. Traditional structural hardware extension methods drive increased costs. Decision makers often overlook the inherent damage tolerance and fatigue capability of structural components and rely on simple time- and flight-based cycle accumulation when determining aircraft retirement lives. This study demonstrates that decision makers should consider risk in addition to the current extension strategies. Through an evaluation of eight military aircraft programs and the application and simulation of F-18 turbine engine usage data, this dissertation shows that insight into actual aircraft mission data, consideration of fatigue capability, and service extension length are key factors to consider. Aircraft structural components, as well as many critical safety components and system designs, have a predefined level of conservatism and inherent damage tolerance. The methods applied in this study would apply to extensions of other critical structures such as bridges. Understanding how much damage tolerance is built into the design compared to the original design usage requirements presents the opportunity to manage systems based on risk. The study presents the sensitivity of these factors and recommends avenues for further research.

    The JEM-EUSO mission will detect extensive air showers produced by extreme energy cosmic rays. It operates from the ISS looking down on Earth's night time atmosphere to detect the nitrogen fluorescence and Cherenkov produce by the charged particles in the EAS. The JEM-EUSO science objectives require a large field of view, sensitivity to energies below 50 EeV, and must fit within available ISS resources. The JEM-EUSO optic module uses three large diameter, thin plastic lenses with Fresnel surfaces to meet the instrument requirements. A bread-board model of the optic has been manufactured and has undergone preliminary tests. We report the results of optical performance tests and evaluate the present capability to manufacture these optical elements.

  18. Drivers of age-related inflammation and strategies for healthspan extension

    Summary Aging is the greatest risk factor for the development of chronic diseases such as arthritis, type 2 diabetes, cardiovascular disease, kidney disease, Alzheimer’s disease, macular degeneration, frailty, and certain forms of cancers. It is widely regarded that chronic inflammation may be a common link in all these age-related diseases. This raises the provocative question, can one alter the course of aging and potentially slow the development of all chronic diseases by manipulating the mechanisms that cause age-related inflammation? Emerging evidence suggests that pro-inflammatory cytokines interleukin-1 (IL-1) and IL-18 show an age-dependent regulation implicating inflammasome mediated caspase-1 activation in the aging process. The Nod-like receptor (NLR) family of innate immune cell sensors, such as the nucleotide-binding domain, leucine-rich-containing family, pyrin domain-containing-3 (NLRP3) inflammasome controls the caspase-1 activation in myeloid-lineage cells in several organs during aging. The NLRP3 inflammasome is especially relevant to aging as it can get activated in response to structurally diverse damage-associated molecular patterns (DAMPs) such as extracellular ATP, excess glucose, ceramides, amyloids, urate and cholesterol crystals, all of which increase with age. Interestingly, reduction of NLRP3-mediated inflammation prevents age-related insulin-resistance, bone loss, cognitive decline and frailty. NLRP3 is a major driver of age-related inflammation and therefore dietary or pharmacological approaches to lower aberrant inflammasome activation holds promise in reducing multiple chronic diseases of age and may enhance healthspan.

    Rey's Auditory Verbal Learning Test (AVLT) is widely used to evaluate dysfunctional episodic memory. The current study aimed to provide extended age- and gender-specific norms for the German AVLT for individuals older than 50 years. In 690 subjects, a comprehensive medical examination including a structural 3.0-tesla magnetic resonance imaging scan was administered, as well as extensive neuropsychological tests. After controlling for exclusion criteria, 407 subjects were included in the analysis. AVLT performance decreased with age, and women outperformed men. We present age- and gender-specific normative data for the German AVLT from subjects aged between 50 and 70 years.

    2011-01-01

    Knowledge of age sensitivity, the capacity of a behavioral test to reliably detect age-related changes, has utility in the design of experiments to elucidate processes of normal aging. We review the application of these tests in studies of normal aging and compare and contrast the age sensitivity of the Barnes maze, eyeblink classical conditioning, fear conditioning, Morris water maze, and rotorod. These tests have all been implemented to assess normal age-related changes in learning and memory in rodents, which generalize in many cases to age-related changes in learning and memory in all mammals, including humans. Behavioral assessments are a valuable means to measure functional outcomes of neuroscientific studies of aging. Highlighted in this review are the attributes and limitations of these measures in mice in the context of age sensitivity and processes of brain aging. Attributes of these tests include reliability and validity as assessments of learning and memory, well-defined neural substrates, and sensitivity to neural and pharmacological manipulations and disruptions. These tests engage the hippocampus and/or the cerebellum, two structures centrally involved in learning and memory that undergo functional and anatomical changes in normal aging. A test that is less well represented in studies of normal aging, the context pre-exposure facilitation effect (CPFE) in fear conditioning, is described as a method to increase sensitivity of contextual fear conditioning to changes in the hippocampus. Recommendations for increasing the age sensitivity of all measures of normal aging in mice are included, as well as a discussion of the potential of the under-studied CPFE to advance understanding of subtle hippocampus-mediated phenomena.

  3. Uniaxial Tension Test of Slender Reinforced Early Age Concrete Members

    2011-01-01

    The present study aims to obtain the tensile properties of early age concrete based on a uniaxial tension test employing RC slender members. First, the paper shows that concrete strain is equal to the strain of rebar at the mid-span of the RC member. The tensile Young’s modulus and the strain capacity of early age concrete are estimated using strain measurements. The experiment indicated that the tensile Young’s modulus at an early age is higher than the compressive modulus. This observation was similar to one found in a previous investigation which used a direct tension test of early age concrete. Moreover, the paper describes how an empirical equation for mature concrete can be applied to the relation between uniaxial tensile strength and splitting tensile strength even in early age concrete. Based on a uniaxial tension test, the paper proposes an empirical equation for the relationship between standard bond stresses and relative slip. PMID:28824146

    To assess the long-term performance of 72 kV and 230 kV composite long rod insulators different laboratory aging tests have been developed. This paper reports two principal diagnostic tests used to measure the performance of the insulators, the quick flashover salt fog (QFO SF), and the rapid flashover clean fog (RFO CF) tests. The aging processes were: cement coating and clean fog, salt fog, and cement coating and salt fog. Similar sets of insulators were aged also in the field for over three years, and all the insulators evaluated in the laboratory. The cement/salt fog aging process was found to be the most controllable and realistic, when the results were assessed by means of the RFO CF test.

    66 children (M=56.2 mo., SD=10.9), recruited from preschool and daycare centers, were administered two continuous performance tests, one auditory and one visual. Both tests utilized a format with one target and one nontarget. Interstimulus interval was fixed at 1350 msec. for the visual test and 5000 msec. for the auditory test. The visual test produced greater rates of omission and commission errors than the auditory test. Age was significantly related to mean reaction time and response variability for both tests; however, the visual test produced an unexpected pattern of increasing response time across age groups. On both tests omission rates improved significantly with age, while commission rates were consistent across ages 3-6 years. When considering continuous performance test paradigms for preschoolers, 3-yr.-olds may need at least a 4000-msec. interstimulus interval to make a choice for the stimulus cue. Hits following an interstimulus interval shorter than 1400 msec. may reflect younger preschoolers' response to a previous stimulus.

    PubMed

    2014-01-01

    In finite populations, there is selection against demographic stochasticity. In this study, it is shown that an increase in the rate of aging, here defined as an increase in early-life survival at the expense of later survival, may reduce this form of stochasticity. In particular, a trade-off between juvenile and adult survival is highly efficient in reducing demographic stochasticity. Therefore, aging may evolve as a response to selective pressure for reduced demographic stochasticity.

    The results from a study aimed at improving the dynamic and aerodynamic characteristics of composite rotor blades through the use of extension-twist elastic coupling are presented. A set of extension-twist-coupled composite tubular spars, representative of the primary load carrying structure within a helicopter rotor blade, was manufactured using four plies of woven graphite/epoxy cloth 'prepreg.' These spars were non-circular in cross section design and were therefore subject to warping deformations. Three cross-sectional geometries were developed: square, D-shape, and flattened ellipse. Results from free-free vibration tests of the spars were compared with results from normal modes and frequency analyses of companion shell-finite-element models developed in MSC/NASTRAN. Five global or 'non-shell' modes were identified within the 0-2000 Hz range for each spar. The frequencies and associated mode shapes for the D-shape spar were correlated with analytical results, showing agreement within 13.8 percent. Frequencies corresponding to the five global mode shapes for the square spar agreed within 9.5 percent of the analytical results. Five global modes were similarly identified for the elliptical spar and agreed within 4.9 percent of the respective analytical results.

    2014-01-01

    Background Two clinical tests used to assess for neuromuscular control deficits in low back pain (LBP) patients are the prone hip extension (PHE) test and active straight leg raise (ASLR) test. For these tests, it has been suggested examiners classify patients as “positive” or “negative” based on the presence or absence (respectively) of specific “abnormal” lumbopelvic motion patterns. The inter-rater agreement of such a classification scheme has been reported for the PHE test, but not for the ASLR test. In addition, the sensitivity and specificity of such classification schemes have not been reported for either test. The primary objectives of the current study were to investigate: 1) the inter-rater agreement of the examiner-reported classification schemes for these two tests, and 2) the sensitivity and specificity of the classification schemes. Methods Thirty participants with LBP and 40 asymptomatic controls took part in this cross-sectional observational study. Participants performed 3–4 repetitions of each test whilst two examiners classified them as “positive” or “negative” based on the presence or absence (respectively) of specific “abnormal” lumbopelvic motion patterns. The inter-rater agreement (Kappa statistic), sensitivity (LBP patients), and specificity (controls) were calculated for each test. Results Both tests demonstrated substantial inter-rater agreement (PHE test: Kappa = 0.76, 95% CI = 0.57-0.95, p < 0.001; ASLR test: Kappa = 0.76, 95% CI = 0.57-0.96, p < 0.001). For the PHE test, the sensitivity was 0.18-0.27 and the specificity was 0.63-0.78; the odds ratio (OR) of “positive” classifications in the LBP group was 1.25 (95% CI = 0.58-2.72; Examiner 1) and 1.27 (95% CI = 0.52-3.12; Examiner 2). For the ASLR test, the sensitivity was 0.20-0.25 and the specificity was 0.84-0.86; the OR of “positive” classifications in the LBP group was 1.72 (95% CI = 0.75-3.95; Examiner 1) and 1

    Advances in DNA sequencing technologies have prompted a wide range of genomic applications to improve healthcare and facilitate biomedical research. However, privacy and security concerns have emerged as a challenge for utilizing cloud computing to handle sensitive genomic data. We present one of the first implementations of Software Guard Extension (SGX) based securely outsourced genetic testing framework, which leverages multiple cryptographic protocols and minimal perfect hash scheme to enable efficient and secure data storage and computation outsourcing. We compared the performance of the proposed PRESAGE framework with the state-of-the-art homomorphic encryption scheme, as well as the plaintext implementation. The experimental results demonstrated significant performance over the homomorphic encryption methods and a small computational overhead in comparison to plaintext implementation. The proposed PRESAGE provides an alternative solution for secure and efficient genomic data outsourcing in an untrusted cloud by using a hybrid framework that combines secure hardware and multiple crypto protocols.

    2015-03-01

    A rotor blade chord extension system was designed, fabricated and hover tested, using electromechanical and pneumatic actuation. A 1.5 in actuator stroke output in the spanwise direction was converted into chordwise motion of a trailing-edge plate (TEP), via a rigid link. On the hover stand, with a 20 V dc input, the electromechanical actuator was shown to fully extend and retract the plate at rotational speeds up to 385 RPM (which put the system at a centrifugal loading of 209.5 g, or 47.2% of that on a Black Hawk helicopter at 73% span). The configuration was changed to reduce the actuator force requirement for the pneumatic actuator. The rotor test facility allowed a maximum of 105 psi pressure input through the rotary union (significantly lower than the rating of the actuator). At these moderate pressure inputs, full TEP deployment was observed at 315 RPM (140.2 g, or 31.6% of that on a Black Hawk helicopter at 73% span). The model prediction of TEP displacement versus pressure showed good correlation with test results.

    The seismic-fragility response of naturally-aged, nuclear station, safety-related batteries is of interest for two reasons: (1) to determine actual failure modes and thresholds; and (2) to determine the validity of using the electrical capacity of individual cells as an indicator of the end-of-life of a battery, given a seismic event. This report covers the first test series of an extensive program using 12-year old, lead-calcium, Gould NCX-2250 cells, from the James A. Fitzpatrick Nuclear Power Station operated by the New York Power Authority. Seismic tests with three cell configurations were performed using a triaxial shake table: single-cell tests, rigidly mounted; multi-cell (three) tests, mounted in a typical battery rack; and single-cell tests specifically aimed towards examining propagation of pre-existing case cracks. In general the test philosophy was to monitor the electrical properties including discharge capacity of cells through a graduated series of g-level step increases until either the shake-table limits were reached or until electrical failure of the cells occurred. Of nine electrically active cells, six failed during seismic testing over a range of imposed g-level loads in excess of a 1-g ZPA. Post-test examination revealed a common failure mode, the cracking at the abnormally brittle, positive lead bus-bar/post interface; further examination showed that the failure zone was extremely coarse grained and extensively corroded. Presently accepted accelerated-aging methods for qualifying batteries, per IEEE Std. 535-1979, are based on plate growth, but these naturally-aged 12-year old cells showed no significant plate growth.

    The seismic-fragility of naturally-aged nuclear station safety-related batteries is of interest for two reasons: (1) to determine actual failure modes and their thresholds and (2) to determine the validity of using the electrical capacity of individual cells as an indicator of the ''end-of-life'' of a battery if subjected to a seismic event. This report, the second in a test series of an extensive seismic research program, covers the testing of 10-year old lead-calcium Exide FHC-19 cells from the Calvert Cliffs Nuclear Power Station operated by the Baltimore Gas and Electric Company. The Exide cells were tested in two configurations using a triaxial shake table: single-cell tests, both rigidly and loosely mounted; and multicell (three-cell) tests, mounted in a typical battery rack. A total of six electrically active cells was used in the two different cell configurations.

    The Cyclades are known for their extensional tectonics and recently recognized as having significant bivergence with top-to-NNE and top-to-SSW kinematics. Crustal extension and exhumation of the Attic-Cycladic massif, and in some instances metamorphic core complex formation are the result of back arc extension in the wake of Hellenic subduction retreat. Of the western islands, Kea and Kythnos have remained relatively little investigated even given their critical juncture between mainland Attica and the other Cyclades. Mapping by Team ACCEL indicates the islands are dominated by highly-strained middle greenschist facies Chl-Ep schists, calc-silicates and marbles, folded into open structural domes. Characterizing the tectonostratigraphy is a dominant, meter to decameter thick layer of ultramylonitic marble which is preserved in klippen scattered along the edges of the domes. The most recent brittle deformation is recorded as a number of low-angle normal faults which truncate the domal structure; both these brittle and other ductile (e.g. boudinage) kinematics indicate a consistent SW-directed stretching direction. No unequivocal hanging wall rocks have been identified and neither dome contains evidence of Alpine or younger magmatism. Ar-Ar thermochronometry performed on white mica from various lithologies at different structural levels on Kea yield consistent Early to Middle Miocene (21 Ma to 13 Ma) cooling ages. (U-Th)/He apatite cooling ages are between 14 Ma and 7.5 Ma. Although poorly defined, the older cooling ages are in the middle of the dome and along the geomorphic 'spine' which defines the dome's long axis. White mica from Kythnos yield poor age spectra with integrated ages between 22 Ma and 17 Ma, likely indicating mixed mineral populations were analyzed. The (U-Th)/He apatite cooling ages from this dome are all consistently Middle Miocene, with no evident spatial pattern. We interpret the Early to Middle Miocene cooling ages of the Kea and Kythnos

  16. Accelerated aging test results for aerospace wire insulation constructions

    NASA Technical Reports Server (NTRS)

    Dunbar, William G.

    1995-01-01

    Several wire insulation constructions were evaluated with and without continuous glow discharges at low pressure and high temperature to determine the aging characteristics of acceptable wire insulation constructions. It was known at the beginning of the test program that insulation aging takes several years when operated at normal ambient temperature and pressure of 20 C and 760 torr. Likewise, it was known that the accelerated aging process decreases insulation life by approximately 50% for each 10 C temperature rise. Therefore, the first phases of the program, not reported in these test results, were to select wire insulation constructions that could operate at high temperature and low pressure for over 10,000 hours with negligible shrinkage and little materials' deterioration.The final phase of the program was to determine accelerated aging characteristics. When an insulation construction is subjected to partial discharges the insulation is locally heated by the bombardment of the discharges, the insulation is also subjected to ozone and other deteriorating gas particles that may significantly increase the aging process. Several insulation systems using either a single material or combinations of teflon, kapton, and glass insulation constructions were tested. All constructions were rated to be partial discharge and/or corona-free at 240 volts, 400 Hz and 260 C (500 F) for 50, 000 hours at altitudes equivalent to the Paschen law. Minimum partial discharge aging tests were preceded by screening tests lasting 20 hours at 260 C. The aging process was accelerated by subjecting the test articles to temperatures up to 370 C (700 F) with and without partial discharges. After one month operation with continuous glow discharges surrounding the test articles, most insulation systems were either destroyed or became brittle, cracked, and unsafe for use. Time with space radiation as with partial discharges is accumulative.

    Upper stage and in-space liquid rocket engines are optimized for performance through the use of high area ratio nozzles to fully expand combustion gases to low exit pressures increasing exhaust velocities. Due to the large size of such nozzles and the related engine performance requirements, carbon-carbon (C/C) composite nozzle extensions are being considered for use in order to reduce weight impacts. NASA and industry partner Carbon-Carbon Advanced Technologies (C-CAT) are working towards advancing the technology readiness level of large-scale, domestically-fabricated, C/C nozzle extensions. These C/C extensions have the ability to reduce the overall costs of extensions relative to heritage metallic and composite extensions and to decrease weight by 50%. Material process and coating developments have advanced over the last several years, but hot fire testing to fully evaluate C/C nozzle extensions in relevant environments has been very limited. NASA and C-CAT have designed, fabricated and hot fire tested multiple subscale nozzle extension test articles of various C/C material systems, with the goal of assessing and advancing the manufacturability of these domestically producible materials as well as characterizing their performance when subjected to the typical environments found in a variety of liquid rocket and scramjet engines. Testing at the MSFC Test Stand 115 evaluated heritage and state-of-the-art C/C materials and coatings, demonstrating the capabilities of the high temperature materials and their fabrication methods. This paper discusses the design and fabrication of the 1.2k-lbf sized carbon-carbon nozzle extensions, provides an overview of the test campaign, presents results of the hot fire testing, and discusses potential follow-on development work.

    The aim of this study was to examine the fatigue and recovery in boys and men during a maximal intermittent isometric fatigue test of the knee extensor muscles, by evaluating the electromyogram of vastus lateralis, vastus medialis and biceps femoris. Thirteen boys (10.0 +/- 0.8yrs) and 13 men (26.1 +/- 4.2yrs) were fatigued until torque reached 50% of its initial value. Three and 6 min after, a maximal isometric knee extension test was assessed. Men had faster torque decline during fatigue and slower torque recovery compared with boys. Agonist activity declined in both groups during fatigue but men had greater extent of reduction. After 6 min boys recovered fully in respect to agonist EMG, whereas this was not the case for the men. The lower level of fatigue and faster recovery in boys could be attributed to the limited inhibition that was observed in the boys' agonist muscles, whereas the antagonist activity does not seem to play a role in the fatigue or recovery differences between the groups.

    1987-10-01

    The basis for a recently initiated program on the chemical decontamination of nuclear reactor components and the possible impact of decontamination on extended-life service is described. The incentives for extending plant life beyond the present 40-year limit are discussed, and the possible aging degradation processes that may be accentuated in extended-life service are described. Chemical decontamination processes for nuclear plant primary systems are summarized with respect to their corrosive effects on structural alloys, particularly those in the aged condition. Available experience with chemical cleaning processes for the secondary side of PWR steam generators is also briefly considered. Overall, no severe materials corrosion problems have been found that would preclude the use of these chemical processes, but concerns have been raised in several areas, particularly with respect to corrosion-related problems that may develop during extended service.

    Schwartz, Fabiano Peruzzo; Bottaro, Martim; Celes, Rodrigo Souza; Brown, Lee E.; Nascimento, Francisco Assis de Oliveira

    2010-01-01

    Exercise on an isokinetic device involves three distinct movement phases: acceleration, constant velocity, and deceleration. Inherent in these phases are unique occurrences that may confound test data and, thereby, test interpretation. Standard methods of data reduction like windowing and other techniques consist of removing the acceleration and deceleration phases in order to assure analysis under constant velocity conditions. However, none of these techniques adequately quantify the velocity overshoot (VO) movement artifact which is a result of the devices resistance imposed to the limb. This study tested the influence of VO on isokinetic data interpretation. A computational algorithm was developed to accurately identify each movement phase and to delineate the VO segment. Therefore, the VO was then treated as a fourth and independent phase. A total of sixteen healthy men (26.8 ± 4.7 yrs, 1.76 ± 0.05 m, and 79.2 ± 9.4 kg) performed two sets of ten maximal concentric extension repetitions of their dominant knee (at 60°·s-1 and 180°·s-1), on separate days and in a counterbalanced order, on a Biodex System 3 Pro dynamometer. All the phases of the isokinetic exercise were measured in terms of their biomechanical descriptors and according to the developed algorithm, the windowing method, and a data reduction technique that eliminates the first and last 10° of the total range of motion. Results showed significant differences (p < 0.05) between the constant velocity phases found by each method: the largest segment was obtained with the windowing method; the second one, with the algorithm; and the smallest, with data reduction technique. The point of peak torque was not affected by none of the techniques, but significant differences (p < 0.05) were found between the data including and not including the VO phase, concerning total work, time interval, and average length of load range: VO represents more than 10% of the amount calculated in constant velocity phase

    Testing drugs for anti-aging effects has historically been conducted in mouse life-span studies, but are costly and time consuming, and more importantly, difficult to recapitulate in humans. In addition, life-span studies in mice are not well suited to testing drug combinations that target multiple factors involved in aging. Additional paradigms for testing therapeutics aimed at slowing aging are needed. A new paradigm, designated as the Geropathology Grading Platform (GGP), is based on a standardized set of guidelines developed to detect the presence or absence of low-impact histopathological lesions and to determine the level of severity of high-impact lesions in organs from aged mice. The GGP generates a numerical score for each age-related lesion in an organ, summed for total lesions, and averaged over multiple mice to obtain a composite lesion score (CLS). Preliminary studies show that the platform generates CLSs that increase with the age of mice in an organ-dependent manner. The CLSs are sensitive enough to detect changes elicited by interventions that extend mouse life span, and thus help validate the GGP as a novel tool to measure biological aging. While currently optimized for mice, the GGP could be adapted to any preclinical animal model. © The Author 2017.

    The needs of offspring change as they develop. Thus, parents should concomitantly change their investment based on the age-related needs of the offspring as they mature. Due to the high costs of parental care, it is optimal for parents to exhibit a shift from intense caregiving of young offspring to promoting independence in older offspring. Yet, the neural mechanisms that underlie shifts in parental behavior are poorly understood, and little is known about how the parental brain responds to offspring of different ages. To elucidate mechanisms that relate to shifts in parental behavior as offspring develop, we examined behavioral and neural responses of male and female prairie voles (Microtus ochrogaster), a biparental rodent, to interactions with offspring at different stages of development (ranging from neonatal to weaning age). Importantly, in biparental species, males and females may adjust their behavior differentially as offspring develop. Because the nonapeptides, vasopressin (VP) and oxytocin (OT), are well known for modulating aspects of parental care, we focused on functional activity of distinct VP and OT cell groups within the maternal and paternal brain in response to separation from, reunion (after a brief period of separation) with, or no separation from offspring of different ages. We found several differences in the neural responses of individual VP and OT cell groups that varied based on the age of pups and sex of the parent. Hypothalamic VP neurons exhibit similar functional responses in both mothers and fathers. However, hypothalamic and amygdalar OT neurons exhibit differential functional responses to being separated from pups based on the sex of the parent. Our results also reveal that the developmental stage of offspring significantly impacts neural function within OT, but not VP, cell groups of both mothers and fathers. These findings provide insight into the functional plastic capabilities of the nonapeptide system, specifically in relation

    This study was conducted to evaluate the effects of rhizome powder from the herb Rhodiola rosea, a traditional Western Ukraine medicinal adaptogen, on lifespan and age-related physiological functions of the fruit fly Drosophila melanogaster. Flies fed food supplemented with 5.0 mg/ml and 10.0 mg/ml of R. rosea rhizome powder had a 14% to 17% higher median lifespan, whereas at 30.0 mg/ml lifespan was decreased by 9% to 12%. The preparation did not decrease fly fecundity.The effect of R. rosea supplement on lifespan was dependent on diet composition. Lifespan extension by 15% to 21% was observed only for diets with protein-to-carbohydrate ratios less than 1. Lifespan extension was also dependent on total concentration of macronutrients. Thus, for the diet with 15% yeast and 15% sucrose there was no lifespan extension, while for the diet with protein-to-carbohydrate ratio 20:1 R. rosea decreased lifespan by about 10%.Flies fed Rhodiola preparation were physically more active, less sensitive to the redox-cycling compound menadione and had a longer time of heat coma onset compared with controls. Positive effects of Rhodiola rhizome on stress resistance and locomotor activity were highest at the 'middle age'. The present data show that long-term food supplementation with R. rosea rhizome not only increases D. melanogaster lifespan, but also delays age-related decline of physical activity and increases stress resistance, what depends on protein-to-carbohydrate ratio of the diet.

    Establishing the age of individuals is an important step in identification and a frequent challenge in forensic medicine. This can be done with high precision up to adolescence by analysis of dentition, but establishing the age of adults has remained difficult. Here we show that measuring {sup 14}C from nuclear bomb tests in tooth enamel provides a sensitive way to establish when a person was born.

    An insulation's performance is of primary concern to the consumer who is considering re-insulating his home. Minnesota Retrofit Insulation In Situ Test Program, published by the Department of Energy in June 1978, details the findings of an in situ study of various thermal insulations installed in 55 residences in the Minneapolis/St. Paul area. The study, conducted in the summer of 1977, consisted of field observations and laboratory measurements of properties critical to the insulations' performance. Properties studied included density, thermal resistance, moisture content, shrinkage, flammability, friability, and compression strength. This study, Phase I, was extended with a second phase to include further in-situ study of retrofit insulations. Included in this extension work, Phase II, was a further study of the moisture content of insulations, the corrosiveness of retrofit loose-fill cellulose insulation, thermography and field observations of sidewalls for signs of settling of retrofit loose-fill insulations, analysis of fuel consumption data for a number of the retrofitted homes, and density and thermal resistance retests of loose-fill insulations. This report details the field and laboratory findings of Phase II.

  6. Slope of the lateral density function of extensive air showers around the knee region as an indicator of shower age

    Analyzing simulated extensive air shower (EAS) events generated with the Monte Carlo code CORSIKA, this paper critically studies the characteristics of lateral distribution of electrons in EAS around the knee energy region of the energy spectrum of primary cosmic rays. The study takes into account the issue of the lateral shower age parameter as an indicator of the stage of development of showers in the atmosphere. The correlation of the lateral shower age parameter with other EAS observables is examined, using simulated data in the context of its possible use in a multi-parameter study of EAS, with a view to obtaining information about the nature of the shower initiating primaries at sea level EAS experiments. It is shown that the observed slope of the lateral density function in the 3-dimensional plot, at least for the KASCADE data, supports the idea of a transition from light to heavy mass composition around the knee.

    To investigate the progression of retinal atrophy in patients with retinal pigment epithelium (RPE) tears secondary to neovascular age-related macular degeneration. In this retrospective case series, patients were analyzed at two high-volume referral centers. The extension of the areas without RPE was analyzed yearly from baseline to last examination through fundus autofluorescence (FAF) imaging using Region Finder (Heidelberg Engineering, Heidelberg, Germany). Sixteen eyes of 14 patients were included in the study. Mean follow-up was 70.11 months ± 15.5 months. The average area of atrophy was 6.89 mm(2) ± 5.4 mm(2) at baseline and 9.21 mm(2) ± 7.7 mm(2) at the last visit (P < .0001). This accounts for a progression of 0.36 mm(2) ± 0.46 mm(2)/year. In all cases, FAF revealed centrifugal extension of retinal atrophy. In this series, the area of retinal atrophy enlarged over time. Atrophy enlargement is characterized by centrifugal extension from the base of the tear. [Ophthalmic Surg Lasers Imaging Retina. 2017;48:705-710.]. Copyright 2017, SLACK Incorporated.

    Subscale liquid engine tests were conducted at NASA/MSFC using a 1.2 Klbf engine with liquid oxygen (LOX) and gaseous hydrogen. Testing was performed for main-stage durations ranging from 10 to 160 seconds at a chamber pressure of 550 psia and a mixture ratio of 5.7. Operating the engine in this manner demonstrated a new and affordable test capability for evaluating subscale nozzles by exposing them to long duration tests. A series of 2D C-C nozzle extensions were manufactured, oxidation protection applied and then tested on a liquid engine test facility at NASA/MSFC. The C-C nozzle extensions had oxidation protection applied using three very distinct methods with a wide range of costs and process times: SiC via Polymer Impregnation & Pyrolysis (PIP), Air Plasma Spray (APS) and Melt Infiltration. The tested extensions were about 6" long with an exit plane ID of about 6.6". The test results, material properties and performance of the 2D C-C extensions and attachment features will be discussed.

    Purpose. To develop a flow model for bovine livers for extensive bench testing of technical improvements or procedure-related developments of radiofrequency ablation excluding animal experiments. Methods. The perfusion of bovine livers directly from the slaughterhouse was simulated in a liver perfusion tank developed for the experimental work. The liver perfusion medium used was a Tyrode solution prepared in accordance with physiologic criteria (as for liver transplants) which was oxygenated by an oxygenator and heated to 36.5 deg. C. Portal vein circulation was regulated via a flow- and pressure-controlled pump and arterial circulation using a dialysis machine. Flow rate and pressure were adjusted as for the physiology of a human liver converted to bovine liver conditions. The fluid discharged from the liver was returned into the perfusion system through the vena cava. Extendable precision swivel arms with the radiofrequency probe attached were mounted on the liver perfusion tank. RFA was conducted with the RF3000 generator and a 2 cm LeVeen needle (Boston Scientific, Ratingen, Germany) in a three-dimensional grid for precise localization of the generated thermolesions. Results. Four bovine livers weighing 8.4 {+-} 0.4 kg each were prepared, connected to the perfusion system, and consecutively perfused for the experiments. Mean arterial flow was 569 {+-} 43 ml/min, arterial pressure 120 mmHg, portovenous flow 1440 {+-} 305 ml/min, and portal pressure 10 mmHg. Macroscopic evaluation after the experiments revealed no thrombi within the hepatic vessels. A total of 136 RF thermolesions were generated with an average number of 34 per liver. Mean RF duration was 2:59 {+-} 2:01 min:sec with an average baseline impedance of 28.2 {+-} 3.4 ohms. The mean diameter of the thermolesions along the puncture channel was 22.98 {+-} 4.34 mm and perpendicular to the channel was 23.27 {+-} 4.82 mm. Conclusion.

    Balance impairment is one of the biggest risk factors for falls reducing inactivity, resulting in nursing care. Therefore, balance ability is crucial to maintain the activities of independent daily living of older adults. Many tests to assess balance ability have been developed. However, few reports reveal the structure underlying results of balance performance tests comparing young and older adults. Covariance structure analysis is a tool that is used to test statistically whether factorial structure fits data. This study examined aging effects on the factorial structure underlying balance performance tests. Participants comprised 60 healthy young women aged 22 ± 3 years (young group) and 60 community-dwelling older women aged 69 ± 5 years (older group). Six balance tests: postural sway, one-leg standing, functional reach, timed up and go (TUG), gait, and the EquiTest were employed. Exploratory factor analysis revealed that three clearly interpretable factors were extracted in the young group. The first factor had high loadings on the EquiTest, and was interpreted as ‘Reactive’. The second factor had high loadings on the postural sway test, and was interpreted as ‘Static’. The third factor had high loadings on TUG and gait test, and was interpreted as ‘Dynamic’. Similarly, three interpretable factors were extracted in the older group. The first factor had high loadings on the postural sway test and the EquiTest and therefore was interpreted as ‘Static and Reactive’. The second factor, which had high loadings on the EquiTest, was interpreted as ‘Reactive’. The third factor, which had high loadings on TUG and the gait test, was interpreted as ‘Dynamic’. A covariance structure model was applied to the test data: the second-order factor was balance ability, and the first-order factors were static, dynamic and reactive factors which were assumed to be measured based on the six balance tests.

    The Contingency Naming Test (CNT; Taylor, Albo, Phebus, Sachs, & Bierl, 1987) was initially designed to assess aspects of executive functioning, such as processing speed and response inhibition, in children. The measure has shown initial utility in identifying differences in executive function among child clinical groups; however, there is an absence of adequate psychometric data for use with adults. The current study expanded psychometric data upward for use with a college student sample and explored the measure's test-retest reliability and factor structure. Performance in the adult sample showed continued improvement above child norms, consistent with theories of executive function development. Exploratory factor analysis showed that the CNT is most closely related to measures of processing speed, as well as elements of response inhibition within the latter trials. Overall, results from the current study provide added support for the utility of the CNT as a measure of executive functioning in young adults. However, more research is needed to determine patterns of performance among adult clinical groups, as well as to better understand how performance patterns may change in a broader age range, including middle and older adulthood.

    We test extensions to the standard cosmological model with weak gravitational lensing tomography using 450 deg2 of imaging data from the Kilo Degree Survey (KiDS). In these extended cosmologies, which include massive neutrinos, non-zero curvature, evolving dark energy, modified gravity and running of the scalar spectral index, we also examine the discordance between KiDS and cosmic microwave background (CMB) measurements from Planck. The discordance between the two data sets is largely unaffected by a more conservative treatment of the lensing systematics and the removal of angular scales most sensitive to non-linear physics. The only extended cosmology that simultaneously alleviates the discordance with Planck and is at least moderately favoured by the data includes evolving dark energy with a time-dependent equation of state (in the form of the w0 - wa parametrization). In this model, the respective S_8=σ _8√{Ω m/0.3} constraints agree at the 1σ level, and there is 'substantial concordance' between the KiDS and Planck data sets when accounting for the full parameter space. Moreover, the Planck constraint on the Hubble constant is wider than in Λ cold dark matter (ΛCDM) and in agreement with the Riess et al. (2016) direct measurement of H0. The dark energy model is moderately favoured as compared to ΛCDM when combining the KiDS and Planck measurements, and marginalized constraints in the w0-wa plane are discrepant with a cosmological constant at the 3σ level. KiDS further constrains the sum of neutrino masses to 4.0 eV (95% CL), finds no preference for time or scale-dependent modifications to the metric potentials, and is consistent with flatness and no running of the spectral index.

    The associate learning subtest from the Wechsler Memory Scale; Benton's Visual Retention test and a Controlled Word Association Task (FAS) were administered to a random sample of normal, healthy individuals whose age ranged from 20 to 79 years, recruited within the Italian peninsula. The neuropsychological examination took place on a mobile unit and the tests were given by the same team of neuropsychologists to reduce variability among examiners. The Research Project was known as Progetto Memoria. Corrections to the scores of these tests were calculated for age, sex, and education. These corrected values will allow clinicians to screen for memory impairment with greater precision among normally aging individuals, thus improving differential diagnosis between physiologic and pathologic deterioration of cognitive functions.

    Personality is an important epidemiological factor for understanding health outcomes. This study investigated the associations of trait procrastination with hypertension and cardiovascular disease (HT/CVD) and maladaptive coping by testing an extension of the procrastination-health model among individuals with and without HT/CVD. Individuals with self-reported HT/CVD (N = 182) and healthy controls (N = 564), from a community sample, completed an online survey including measures of personality, coping, and health outcomes. Logistic regression analysis controlling for demographic and higher order personality factors found that older age, lower education level and higher procrastination scores were associated with HT/CVD. Moderated mediation analyses with bootstrapping revealed that procrastination was more strongly associated with maladaptive coping behaviours in participants with HT/CVD than the healthy controls, and the indirect effects on stress through maladaptive coping were larger for the HT/CVD sample. Results suggest procrastination is a vulnerability factor for poor adjustment to and management of HT/CVD.

    The accuracy of rest and exercise radionuclide angiocardiography (RNA) and exercise treadmill testing (ETT) for diagnosis of three-vessel or left main coronary artery disease (extensive CAD) was determined in 544 patients. ETT and RNA sensitivities were similar (88% vs 92%, NS), but ETT was more specific than RNA (46% vs 34%, p less than 0.01). The prevalence of extensive CAD in patients with a positive treadmill (41%) increased only 3% when the RNA was also positive. However, in the 292 patients with a negative or indeterminate ETT, a positive RNA increased this prevalence from 16% to 23%, while a negative RNA decreased this prevalence to 5%. These results support the initial use of ETT followed by RNA if the treadmill is negative or indeterminate for diagnosis in a population with a high prevalence of extensive CAD. This approach separates patients into subgroups with a high or low probability of extensive CAD.

    This document describes the results of accelerated aging tests to determine the long-term effectiveness of selected impoundment liner materials in a uranium mill tailings environment. The study was sponsored by the US Department of Energy under the Uranium Mill Tailings Remedial Action Project. The study was designed to evaluate the need for, and the performance of, several candidate liners for isolating mill tailings leachate in conformance with proposed Environmental Protection Agency and Nuclear Regulatory Commission requirements. The liners were subjected to conditions known to accelerate the degradation mechanisms of the various liners. Also, a test environment was maintained that modeled the expected conditions at a mill tailings impoundment, including ground subsidence and the weight loading of tailings on the liners. A comparison of installation costs was also performed for the candidate liners. The laboratory testing and cost information prompted the selection of a catalytic airblown asphalt membrane and a sodium bentonite-amended soil for fiscal year 1981 field testing.

    An aging evaluation program has been developed for the United States Department of Energy's Advanced Test Reactor to support the current goal of operation through the year 2014 and beyond. The Aging Evaluation and Life Extension Program (AELEX) employs a three-phased approach. In Phases 1 and 2, now complete, components were identified, categorized and prioritized. Critical components were selected and aging mechanisms for the critical components identified. An initial evaluation of the critical components was performed and extended life operation for the plant appears to be both technically and economically feasible. Detailed evaluations of the critical components are now in progress in the early stages of Phase 3. Some results are available. Evaluations of many non-critical components and refinements to the program based on probabilistic risk assessment results will follow in later stages of Phase 3. 6 refs., 2 figs., 5 tabs.

    Widespread Amazonian-aged fluvial channels have been mapped proximal to Lyot crater, a 225 km diameter impact basin in the northern lowlands of Mars. Comparable in area to some Noachian/Hesperian fluvial systems, their morphology differs, being dominated by broad, shallow braided channels. Using new developments in the study of cratering, water inventory, and climate history, we assess eight different models for their origin. Dewatering of excavated ice-rich Lyot ejecta and contact melting from hot Lyot ejecta superposed on surface ice deposits are the most plausible channel origins. The existence of this extensive Amazonian fluvial system is attributed to: (1) the large size of Lyot, and its consequent hot ejecta, and (2) the presence of surface ice at the time of impact, attributed to obliquity changes redistributing polar ice to the mid-latitudes, a relatively common occurrence in Martian geologic history.Plain Language SummaryA vast network of relatively young broad and shallow fluvial channels were previously mapped near Lyot crater, a 225 km diameter impact basin located in one of the lowest regions of Mars. These channels are highly unusual based on their young <span class="hlt">age</span> and dispersed scour morphology. We use new developments in the study of cratering, water inventory, and climate history to assess different models for the origin of these channels. We find that the fluvial channels likely formed through runoff of water derived from dewatering of melted pore ice from within the ejecta and/or meltwater from contact melting of hot Lyot ejecta superposed on a regional surface ice sheet. The existence of this <span class="hlt">extensive</span> young fluvial system is attributed to: (1) the large size of Lyot, and its consequent hot ejecta, and (2) the presence of surface ice at the time of impact, attributed to obliquity changes redistributing polar ice to the mid-latitudes, a relatively common occurrence in Martian geologic history.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://adsabs.harvard.edu/abs/2013AIPC.1556..226M','NASAADS'); return false;" href="http://adsabs.harvard.edu/abs/2013AIPC.1556..226M"><span>CPV solar receiver <span class="hlt">ageing</span> <span class="hlt">tests</span>: The enhanced electroluminescence method</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Mabille, Loïc; Mangeant, Christophe; Baudrit, Mathieu</p> <p>2013-09-01</p> <p>For two years now, CEA INES is involved in the development of insulated metal substrates (IMS) for CPV receivers.

Key features include: (i) use of genetically heterogeneous mice (a standardized four-way cross), (ii) replication at three <span class="hlt">test</span> sites (the Jackson Laboratory, TJL; University of Michigan, UM; and University of Texas, UT), (iii) sufficient statistical power to detect 10% changes in lifespan, (iv) <span class="hlt">tests</span> for <span class="hlt">age</span>-dependent changes in T cell subsets and physical activity, and (v) an annual solicitation for collaborators who wish to suggest new interventions for evaluation. Mice in the first cohort were exposed to one of four agents: aspirin, nitroflurbiprofen (NFP), 4-OH-alpha-phenyl-N-tert-butyl nitrone (4-OH-PBN), or nordihydroguiaretic acid (NDGA). An interim analysis was conducted using survival data available on the date at which at least 50% of the male control mice had died at each <span class="hlt">test</span> site. Survival of control males was significantly higher, at the interim time-point, at UM than at UT or TJL; all three sites had similar survival of control females. Males in the NDGA group had significantly improved survival (P = 0.0004), with significant effects noted at TJL (P < 0.01) and UT (P < 0.04). None of the other agents altered survival, although there was a suggestion (P = 0.07) of a beneficial effect of aspirin in males. More data will be needed to determine if any of these compounds can extend maximal lifespan, but the current data show that NDGA reduces early life mortality risks in genetically heterogeneous mice at multiple <span class="hlt">test</span> sites.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://adsabs.harvard.edu/abs/2017MMTA..tmp..477F','NASAADS'); return false;" href="http://adsabs.harvard.edu/abs/2017MMTA..tmp..477F"><span><span class="hlt">Extension</span> of the Mechanical Threshold Stress Model to Static and Dynamic Strain <span class="hlt">Aging</span>: Application to AA5754-O</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Feng, Yu; Mandal, Sudipto; Gockel, Brian; Rollett, Anthony D.</p> <p>2017-08-01</p> <p>Based on the mechanical threshold stress model and the visco-plastic self-consistent algorithm, a modified constitutive model is developed to model static strain <span class="hlt">aging</span> and dynamic strain <span class="hlt">aging</span> for application to a non-heat treatable aluminum alloy, AA5754-O.

The approach involves quantitative description of the oxidative stress theory of <span class="hlt">aging</span>, which is presented in the form of a mathematical homeostatic model. The crucial variable in the model is called 'homeostatic capacity', which is analogous to the classical notion of vitality. We model the process of <span class="hlt">aging</span> as the <span class="hlt">age</span>-related accumulation of damage produced by oxidative stress, which reduces the homeostatic capacity of the organism.

We form an hypothesis about the mechanisms underlying the results observed in the experiments and analyze a possible interplay of these mechanisms.

Computerized assessment may be uniquely suited to early detection of changes in cognition in the elderly. We present here a systematic review of the status of computer-based cognitive <span class="hlt">testing</span> focusing on detection of cognitive decline in the <span class="hlt">aging</span> population. Methods All studies purporting to assess or detect <span class="hlt">age</span>-related changes in cognition or early dementia/mild cognitive impairment (MCI) by means of computerized <span class="hlt">testing</span> were included. Each <span class="hlt">test</span> battery was rated on availability of normative data, level of evidence for <span class="hlt">test</span> validity and reliability, comprehensiveness, and usability. All published studies relevant to a particular computerized <span class="hlt">test</span> were read by a minimum of two reviewers, who completed rating forms containing the above-mentioned criteria. Results Of the 18 <span class="hlt">test</span> batteries identified from the initial search, eleven were appropriate to cognitive <span class="hlt">testing</span> in the elderly and were subjected to systematic review. Of those 11, five were either developed specifically for application with the elderly or have been used <span class="hlt">extensively</span> with that population. Even within the computerized <span class="hlt">testing</span> genre, great variability existed in manner of administration, ranging from fully examiner administered to fully self-administered. All <span class="hlt">tests</span> had at least minimal reliability and validity data, commonly reported in peer-reviewed articles. However, level of rigor of validity <span class="hlt">testing</span> varied widely. Conclusion All <span class="hlt">test</span> batteries exhibited some of the strengths of computerized cognitive <span class="hlt">testing</span>: standardization of administration and stimulus presentation, accurate measures of response latencies, automated comparison in real-time with an individual’s prior performance as well as with <span class="hlt">age</span>-related norms, and efficiencies of staffing and cost.

This work examined the <span class="hlt">aging</span>-related effects of temporal pressure on movement synchronization and dynamic stability. Sixteen young and eleven elderly subjects performed series of simultaneous rapid leg flexions in an erect posture paired with ipsilateral index-finger <span class="hlt">extensions</span>, minimizing the difference between heel and finger movement onsets. This task was repeated ten times under two temporal conditions (self-initiated [SI] vs. reaction-time [RT]). Results showed that, first, temporal pressure modified movement synchronization; the finger <span class="hlt">extension</span> preceded swing heel-off in RT, and inversely in SI. Synchronization error and associated standard deviation were significantly greater in elderly than in young adults in SI only, i.e. in the condition where proprioception is thought to be crucial for temporal coordination. Secondly, both groups developed a significantly shorter mediolateral (ML) anticipatory postural adjustment duration in RT (high temporal pressure) than in SI. In both groups, this shortening was compensated by an increase in the anticipatory peak of centre-of-gravity (CoG) acceleration towards the stance-leg so that ML dynamic stability at foot-off, quantified with the “extrapolated centre-of-mass”, remained unchanged across temporal conditions. This increased CoG acceleration was associated with an increased anticipatory peak of ML centre-of-pressure shift towards the swing-leg in young adults only. This suggested that the ability to accelerate the CoG with the centre-of-pressure shift was degraded in elderly, probably due to weakness in the lower limb muscles. Dynamic stability at foot-off was also degraded in elderly, with a consequent increased risk of ML imbalance and falling.

Yet, this interpretation rests on empirical assumptions about the uniformity of item-response functions between groups. In this article, we <span class="hlt">test</span> item response models of differential responding against datasets containing younger-, middle-<span class="hlt">aged</span>-, and older-adult responses to three popular vocabulary <span class="hlt">tests</span> (the Shipley, Ekstrom, and WAIS-R) to determine whether members of different <span class="hlt">age</span> groups who achieve the same scores have the same probability of responding in the same categories (e.g., correct vs. incorrect) under the same conditions. Contrary to the null hypothesis of measurement invariance, datasets for all three <span class="hlt">tests</span> exhibit substantial differential responding. Members of different <span class="hlt">age</span> groups who achieve the same overall scores exhibit differing response probabilities in relation to the same items (differential item functioning) and appear to approach the <span class="hlt">tests</span> in qualitatively different ways that generalize across items. Specifically, younger adults are more likely than older adults to leave items unanswered for partial credit on the Ekstrom, and to produce 2-point definitions on the WAIS-R. Yet, older adults score higher than younger adults, consistent with most reports of vocabulary outcomes in the cognitive <span class="hlt">aging</span> literature. In light of these findings, the most generalizable conclusion to be drawn from the cognitive <span class="hlt">aging</span> literature on vocabulary <span class="hlt">tests</span> is simply that older adults tend to score higher than younger adults, and not that older adults possess more of a common ability.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('https://www.gpo.gov/fdsys/pkg/FR-2013-11-25/pdf/2013-28074.pdf','FEDREG'); return false;" href="https://www.gpo.gov/fdsys/pkg/FR-2013-11-25/pdf/2013-28074.pdf"><span>78 FR 70324 - Thy Hydrostatic <span class="hlt">Testing</span> Provision of the Portable Fire Extinguishers Standard; <span class="hlt">Extension</span> of the...</span></a></p> <p><a target="_blank" href="http://www.gpo.gov/fdsys/browse/collection.action?collectionCode=FR">Federal Register 2010, 2011, 2012, 2013, 2014</a></p> <p></p> <p>2013-11-25</p> <p>...

The chambers were irradiated over a large area: in total, about 2.1 m{sup 2} or 700 m of wire in each chamber. The 40% Ar+50%CO{sub 2}+10%CF{sub 4} gas mixture was provided by an open-loop gas system for one of the chambers and by closed-loop recirculating gas system for the other. After accumulating 0.3-0.4 C per centimeter of a wire, which is equivalent to operation during about 30-50 years at the peak LHC luminosity, no significant changes in gas gain, chamber efficiency, and wire signal noise were observed for either of the two chambers. The only consistent signs of <span class="hlt">aging</span> were a small increase in dark current from {approx}2 nA to {approx}10 nA per plane of 600 wires and a decrease of strip-to-strip resistance from 1000 G{Omega} to 10-100 G{Omega}. Disassembly of the chambers revealed deposits on the cathode planes, while the anode wires remained fairly clean.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.dtic.mil/docs/citations/ADA598110','DTIC-ST'); return false;" href="http://www.dtic.mil/docs/citations/ADA598110"><span>Surfzone Bubbles: Model Development, <span class="hlt">Testing</span> and <span class="hlt">Extension</span> to Sedimentary/Chemical/Biological Processes</span></a></p> <p><a target="_blank" href="http://www.dtic.mil/">DTIC Science & Technology</a></p> <p></p> <p>2013-09-30</p> <p>inundation", Ocean Modelling, 43-44, 36-51.

Based on DPT we have derived a Dual Processing Model (DPM) to describe and explain therapeutic medical decision-making. The DPM model indicates that doctors decide to treat when treatment benefits outweigh its harms, which occurs when the probability of the disease is greater than the so called "threshold probability" at which treatment benefits are equal to treatment harms. Here we extend our work to include a wider class of decision problems that involve diagnostic <span class="hlt">testing</span>. We illustrate applicability of the proposed model in a typical clinical scenario considering the management of a patient with prostate cancer. To that end, we calculate and compare two types of decision-thresholds: one that adheres to expected utility theory (EUT) and the second according to DPM. Our results showed that the decisions to administer a diagnostic <span class="hlt">test</span> could be better explained using the DPM threshold. This is because such decisions depend on objective evidence of <span class="hlt">test</span>/treatment benefits and harms as well as type 1 cognition of benefits and harms, which are not considered under EUT. Given that type 1 processes are unique to each decision-maker, this means that the DPM threshold will vary among different individuals. We also showed that when type 1 processes exclusively dominate decisions, ordering a diagnostic <span class="hlt">test</span> does not affect a decision; the decision is based on the assessment of benefits and harms of treatment. These findings could explain variations in the treatment and diagnostic patterns documented in today's clinical practice.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('https://www.ncbi.nlm.nih.gov/pubmed/23098283','PUBMED'); return false;" href="https://www.ncbi.nlm.nih.gov/pubmed/23098283"><span>Time-domain microwave breast cancer detection: <span class="hlt">extensive</span> system <span class="hlt">testing</span> with phantoms.</span></a></p> <p><a target="_blank" href="https://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pubmed">PubMed</a></p> <p>Porter, Emily; Santorelli, Adam; Coates, Mark; Popovic, Milica</p> <p>2013-04-01</p> <p>Early detection of breast cancer is known to be a key factor in the successful treatment of the disease. Here, we present a detection technique complementary to the currently used modalities (primarily mammography, ultrasound and magnetic resonance imaging). Our time-domain breast cancer detection system transmits microwave-range pulses into the breast and records the scattering off of the breast in order to detect malignancies. This method is made possible by an intrinsic contrast in the dielectric parameters, specifically the relative permittivity and conductivity, of the healthy and malignant breast tissues over the microwave frequency range. The long-term goal of our work is to develop a system that can be used periodically to monitor for unusual changes in breast tissues; for instance, healthy breasts would be scanned, and follow-up scans at regular intervals would detect any small changes in breast tissue composition that could indicate the presence of a malignant growth. At that point, the patient would be referred to see a doctor for further investigation of the abnormal results. Such a system would compare each new scan with previous ones to determine the level of tissue changes, and would be used by patients at home. We report feasibility and performance <span class="hlt">tests</span> for our initial system, conducted with breast phantoms made up of tissue-mimicking materials (unique skin, fat, gland and tumor mixtures). We initiated the system <span class="hlt">testing</span> with simple homogeneous phantoms, consisting solely of adipose tissue. Then, we extended our <span class="hlt">tests</span> to cases of increasing complexity by adding a skin layer and varying percentages of glandular structures and tumor sizes. In order to optimize the experimental system, we performed <span class="hlt">tests</span> with multiple antenna arrangements, tumor sizes and locations.

However, there is disagreement as to whether opening light rail lines attracts new ridership or merely draws ridership from existing transit users. We study a new light rail line in Salt Lake City, Utah, USA, which is part of a complete street redevelopment. We utilize a pre-<span class="hlt">test</span> post-<span class="hlt">test</span> control group quasi-experimental design to <span class="hlt">test</span> two different measures of ridership change. The first measure is calculated from stops along the light rail route; the second assumes that nearby bus stops might be displaced by the rail and calculates ridership change with those stops included as baseline. Both the simple measure (transit use changes on the complete street light rail corridor) and the “displacement” measure (transit use changes in the one-quarter mile catchment areas around new light rail stops) showed significant (p < .01) and substantial (677%) increases in transit passengers compared to pre-light rail bus users. In particular, the displacement analysis discredits a common challenge that when a new light rail line opens, most passengers are simply former bus riders whose routes were canceled in favor of light rail. The study suggests that light rail services can attract additional ridership to public transit systems. In addition, although pre-post control-group designs require time and effort, this project underscores the benefits of such quasi-experimental designs in terms of the strength of the inferences that can be drawn about the impacts of new transit infrastructure and services.

Improvements to the 2nd edition of the <span class="hlt">test</span> (M-ABC-2) include an <span class="hlt">extension</span> of the <span class="hlt">age</span> range and reduction in the number of <span class="hlt">age</span> bands as well as revision of tasks. The total <span class="hlt">test</span> score provides a measure of motor performance, which can be used to help make a diagnosis of DCD. M-ABC-2 also provides 3 sub-scales for Manual Dexterity, Aiming and Catching and Balance but the validity of these conceptually derived sub-scales has not previously been reported. To examine the factor structure of the M-ABC-2 <span class="hlt">test</span> across the three <span class="hlt">age</span> bands (AB): AB1 (3-6-year olds), AB2 (7-10-year olds) and AB3 (11-16-year olds). Data from the 2007 standardisation sample (N=1172) were used in this study. Confirmatory factor analyses (CFA) and structural equation modelling (LISREL 8.8) were employed to explore the relationship between the tasks within each of the 3 <span class="hlt">age</span> bands. A model trimming approach was used to arrive at a well fitting model. In AB1 a complex factor structure emerged providing evidence for an independent general factor, as well as specific factors representing the 3 <span class="hlt">test</span> components. In AB2 a final model emerged with four correlated factors, an additional distinction being drawn between static and dynamic balance. In addition, a 2nd order general factor explained a considerable amount of variance in each primary factor. In AB3 CFA supported the 3-factor structure of the M-ABC-2, with only modest correlations between each factor. The confirmatory factor analyses undertaken in this study further validate the structural validity of the M-ABC-2 as it has developed over time. Although its tasks are largely associated with the three sub-components within each <span class="hlt">age</span> band, there was also clear evidence for a change in the factor structure towards differentiation in motor abilities with <span class="hlt">age</span>.

Design: we compared the performance in the leg <span class="hlt">extension</span> <span class="hlt">test</span> and the response in the sEMG activity to vibration in the operated to the non-operated leg. Thirty-eight patients with knee operation and 14 healthy subjects participated in these experiments. Results: during leg <span class="hlt">extension</span> <span class="hlt">test</span>, the mechanical power of the operated leg showed a lower value (P<0.001) than the contralateral one, while no differences were noted in the sEMG activity. The sEMG activity during vibration treatment was higher in the operated compared to non-operated leg (P<0.001). It has been suggested that the reduced motility trigger functional adaptations that are exhibited via the vibration <span class="hlt">test</span>. Conclusions: results of our study suggest that combination of vibration and sEMG recordings may detect the impairment as well as monitoring progress of the rehabilitation programs.

Document strength data normalized to the individual's limb muscle mass. Observational and reliability study. Inter-rater reliability for each of the hand-held dynamometry measures was established in both legs of 10 volunteers (6 male). During routine annual screening, 216 male professional football (soccer) players were examined using these same measures in addition to performing an isokinetic evaluation of knee flexion and <span class="hlt">extension</span> strength. Intra-class correlation coefficients for inter-rater reliability, Pearson r correlations between hand-held dynamometry and isokinetic dynamometry were calculated. Peak torque, peak torque normalized to: body weight; lean body mass; and lean limb mass were documented. Excellent inter-rater reliability was demonstrated with intra-class correlation₂,₁ values of 0.90, 0.91, and 0.96, for the eccentric hamstrings, isometric hamstrings, and isometric quadriceps measures respectively. Medium to high correlations (r=0.322-0.617) which were all significant (p<0.001) were found for the comparisons between the hand-held dynamometry and isokinetic measures. We present 3 novel and reliable methods of examining knee flexion and <span class="hlt">extension</span> strength using hand-held dynamometry which require less skill and strength on the part of the examiner than previous measures. Correlations between these measures and isokinetic dynamometry are documented. The hand-held dynamometry examinations took less than 4 min per player to conduct and may be useful in clinical practice where isokinetic examination can be difficult to implement.

Application of the uranium comminution <span class="hlt">age</span> method, which has great potential in tracing production and transportation of sediments is however complicated by the weathering dissolution of 234U depleted particle surfaces, the difficulty in determining the fraction of recoiled nuclei, and the precipitation of exogenetic 234U. Here we minimize these complications by using a newly developed precise size separation using electroformed sieve, and a chemical protocol that involves reductive and oxidative leaching. Eolian deposits collected from the Chinese Loess Plateau (CLP) were used to <span class="hlt">test</span> the validity of our method. Possible effects of weathering dissolution were also evaluated by comparing samples with different weathering intensities. The results show decreasing 234U/238U ratios in fine eolian particles with increasing sedimentation <span class="hlt">age</span>, agreeing well with the theoretical prediction of the comminution <span class="hlt">age</span> model. This successful application of the uranium comminution <span class="hlt">age</span> approach to the eolian deposits on the CLP is also aided by a stable dust source, the low weathering intensity, the lack of consolidation, and the well-defined <span class="hlt">age</span> model of the deposits.

N.; Thoss, H.; Güntner, A.; Apel, H.</p> <p>2009-04-01</p> <p>Monitoring of floodplain inundation is one of the key issues in respect to hydraulic model calibration, especially for 2-dimensional modeling of floodplains. While in recent years the use of remote sensing products for flood mapping have received a large boost by new techniques and platforms (LiDAR, SAR, optical system, both satellite and airborn) and proved to be a significant step forward in floodplain inundation model calibration, they are not the encompassing answer to the chronic lack of data of floodplain inundation. Due to the singular nature of floods and restrictions in sensor availability, overpass frequencies, unfavorable atmospheric conditions and difficulties in signal interpretation, remote sensing products usually provide only a short but spatially <span class="hlt">extensive</span> view on the inundation process. In order to get a more encompassing picture of the inundation dynamics, time series of flood parameters have to be collected in the floodplains itself. In order to overcome the intrinsic problem of <span class="hlt">testing</span> flood monitoring equipment in a short termed research project, an <span class="hlt">extensive</span> ground-based flood monitoring system was established within the WISDOM (www.wisdom.caf.dlr.de)project in the Mekong Delta. Due to annual flood rhythm flood condition could be guaranteed within the projects duration. For the flood season 2008 the <span class="hlt">test</span> site Tam Nong in the Plain of Reeds in the Delta was equipped with 21 water level pressure gauges, 7 turbidity sensors and 2 GPS buoys, all designed to run autonomously for a period of 6 month and sampling data in short termed intervals. The collected data show a detailed picture of the inundation and sediment dynamics in the whole area including tidal influence and dike overtopping. This unique data set will be used in combination with spatial explicit water masks derived by remote sensing for 2D hydraulic model calibration in the next step.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('https://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pmcentrez&artid=4022280','PMC'); return false;" href="https://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pmcentrez&artid=4022280"><span>Synaptic genes are <span class="hlt">extensively</span> downregulated across multiple brain regions in normal human <span class="hlt">aging</span> and Alzheimer’s disease</span></a></p> <p><a target="_blank" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pmc">PubMed Central</a></p> <p>Berchtold, Nicole C.; Coleman, Paul D.; Cribbs, David H.; Rogers, Joseph; Gillen, Daniel L.; Cotman, Carl W.</p> <p>2014-01-01</p> <p>Synapses are essential for transmitting, processing, and storing information, all of which decline in <span class="hlt">aging</span> and Alzheimer’s disease (AD). Because synapse loss only partially accounts for the cognitive declines seen in <span class="hlt">aging</span> and AD, we hypothesized that existing synapses might undergo molecular changes that reduce their functional capacity. Microarrays were used to evaluate expression profiles of 340 synaptic genes in <span class="hlt">aging</span> (20–99 years) and AD across 4 brain regions from 81 cases. The analysis revealed an unexpectedly large number of significant expression changes in synapse-related genes in <span class="hlt">aging</span>, with many undergoing progressive downregulation across <span class="hlt">aging</span> and AD. Functional classification of the genes showing altered expression revealed that multiple aspects of synaptic function are affected, notably synaptic vesicle trafficking and release, neurotransmitter receptors and receptor trafficking, postsynaptic density scaffolding, cell adhesion regulating synaptic stability, and neuromodulatory systems. The widespread declines in synaptic gene expression in normal <span class="hlt">aging</span> suggests that function of existing synapses might be impaired, and that a common set of synaptic genes are vulnerable to change in <span class="hlt">aging</span> and AD.

Methods In a well-powered microarray study of young (20 to 59 years), <span class="hlt">aged</span> (60 to 99 years), and AD (74 to 95 years) cases, gene responses were assessed in the hippocampus, entorhinal cortex, superior frontal gyrus, and post-central gyrus. Results Several novel concepts emerge. First, immune/inflammation-related genes showed major changes in gene expression over the course of cognitively normal <span class="hlt">aging</span>, with the extent of gene response far greater in <span class="hlt">aging</span> than in AD. Of the 759 immune-related probesets interrogated on the microarray, approximately 40% were significantly altered in the SFG, PCG and HC with increasing <span class="hlt">age</span>, with the majority upregulated (64 to 86%). In contrast, far fewer immune/inflammation genes were significantly changed in the transition to AD (approximately 6% of immune-related probesets), with gene responses primarily restricted to the SFG and HC. Second, relatively few significant changes in immune/inflammation genes were detected in the EC either in <span class="hlt">aging</span> or AD, although many genes in the EC showed similar trends in responses as in the other brain regions.

In forensic genetics, the mtDNA control region (CR) is commonly sequenced using established Sanger-type Sequencing (STS) protocols involving fragment sizes down to approximately 150 base pairs (bp). Recent developments include Massively Parallel Sequencing (MPS) of (multiplex) PCR-generated libraries using the same amplicon sizes. Molecular genetic studies on archaeological remains that harbor more degraded aDNA have pioneered alternative approaches to target mtDNA, such as capture hybridization and primer <span class="hlt">extension</span> capture (PEC) methods followed by MPS. These assays target smaller mtDNA fragment sizes (down to 50 bp or less), and have proven to be substantially more successful in obtaining useful mtDNA sequences from these samples compared to electrophoretic methods. Here, we present the modification and optimization of a PEC method, earlier developed for sequencing the Neanderthal mitochondrial genome, with forensic applications in mind. Our approach was designed for a more sensitive enrichment of the mtDNA CR in a single tube assay and short laboratory turnaround times, thus complying with forensic practices. We characterized the method using sheared, high quantity mtDNA (six samples), and <span class="hlt">tested</span> challenging forensic samples (n = 2) as well as compromised solid tissue samples (n = 15) up to 8 kyrs of <span class="hlt">age</span>. The PEC MPS method produced reliable and plausible mtDNA haplotypes that were useful in the forensic context. It yielded plausible data in samples that did not provide results with STS and other MPS techniques. We addressed the issue of contamination by including four generations of negative controls, and discuss the results in the forensic context.

Yet, in fact, these studies, explicitly aiming to prolong human life, often constituted a formidable, though hardly ever acknowledged, motivation for biomedical research and discovery. At least several modern biomedical fields have originated directly from rejuvenation and life <span class="hlt">extension</span> research: (1) Hormone replacement therapy was born in Charles-Edouard Brown-Séquard's rejuvenation experiments with animal gland extracts (1889). (2) Probiotic diets originated in Elie Metchnikoff's conception of radically prolonged "orthobiosis" (c. 1900). (3) The development of clinical endocrinology owed much to Eugen Steinach's "endocrine rejuvenation" operations (c. 1910s-1920s). (4) Tissue transplantations in humans (allografts and xenografts) were first widely performed in Serge Voronoff's "rejuvenation by grafting" experiments (c. 1910s-1920s). (5) Tissue engineering was pioneered during Alexis Carrel's work on cell and tissue immortalization (c. 1900-1920). (6) Cell therapy (and particularly human embryonic cell therapy) was first widely conducted by Paul Niehans for the purposes of rejuvenation as early as the 1930s. Thus, the pursuit of life <span class="hlt">extension</span> and rejuvenation has constituted an inseparable and crucial element in the history of biomedicine. Notably, the common principle of these studies was the proactive maintenance of stable, long-term homeostasis of the entire organism.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://adsabs.harvard.edu/abs/2017JCoMa..51..153B','NASAADS'); return false;" href="http://adsabs.harvard.edu/abs/2017JCoMa..51..153B"><span>Bias <span class="hlt">extension</span> <span class="hlt">test</span> on an unbalanced woven composite reinforcement: Experiments and modeling via a second-gradient continuum approach</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Barbagallo, Gabriele; Madeo, Angela; Azehaf, Ismael; Giorgio, Ivan; Morestin, Fabrice; Boisse, Philippe</p> <p>2017-01-01</p> <p>The classical continuum models used for the woven fabrics do not fully describe the whole set of phenomena that occur during the <span class="hlt">testing</span> of those materials. This incompleteness is partially due to the absence of energy terms related to some micro-structural properties of the fabric and, in particular, to the bending stiffness of the yarns. To account for the most fundamental microstructure-related deformation mechanisms occurring in unbalanced interlocks, a second-gradient, hyperelastic, initially orthotropic continuum model is proposed. A constitutive expression for the strain energy density is introduced to account for i) in-plane shear deformations, ii) highly different bending stiffnesses in the warp and weft directions and iii) fictive elongations in the warp and weft directions which eventually describe the relative sliding of the yarns. Numerical simulations which are able to reproduce the experimental behavior of unbalanced carbon interlocks subjected to a Bias <span class="hlt">Extension</span> <span class="hlt">Test</span> are presented.

A challenge was performed in 52/72 infants with suspected CMPA and was positive in 65.4%. All confirmed CMPA cases tolerated eCH. The symptom-based score decreased significantly in all infants within a month, and the highest reduction was in those with confirmed CMPA. Regurgitation was reduced in all infants (6.4 ± 3.2-2.8 ± 2.9, p < 0.001), but fell more with the T-eCH (-4.2 ± 3.2 regurgitations/day vs. -3.0 ± 4.5, ns), especially in infants with a negative challenge (-3.9 ± 4.0 vs. -1.9 ± 3.4, ns). eCH fulfilled the criteria for a hypoallergenic formula, and the NT-eCH and T-eCH formulas both reduced CMPA symptoms.

The analysis described in this report shows that, based on the current data analysis, two of these measurements, Upper Assembly Outer Diameter (UAOD) and Upper Assembly Inside Height (UAIH), do not have statistically significant <span class="hlt">aging</span> trends regardless of wattage levels. In contrast, this analysis indicates that the measurement of Air Shield Gap (ASGap) does show a significant increase with <span class="hlt">age</span>. It appears that the increase is greater for high wattage containers, but this result is dominated by two measurements from high-wattage containers. For all three indicators, additional high-wattage, older containers need to be examined before any definitive conclusions can be reached. In addition, the current analysis indicates that ASGap measurements for low and medium wattage containers are increasing slowly over time. To reduce uncertainties and better capture the <span class="hlt">aging</span> trend for these containers, additional low and medium wattage older containers should also be examined. Based on this analysis, surveillance guidance is to augment surveillance containers resulting from 3013 surveillance with 9975-focused sampling that targets older, high wattage containers and also includes some older, low and medium wattage containers. This focused sampling began in 2015 and will continue in 2016. The UAOD, UAIH and ASGap data are highly variable. It is possible that additional factors such as seasonal variation and packaging site location might reduce variability and be useful for focusing surveillance and predicting <span class="hlt">aging</span>.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('https://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pmcentrez&artid=4258766','PMC'); return false;" href="https://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pmcentrez&artid=4258766"><span>Fetuses-at-risk, to avoid paradoxical associations at early gestational <span class="hlt">ages</span>: <span class="hlt">extension</span> to preterm infant mortality</span></a></p> <p><a target="_blank" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pmc">PubMed Central</a></p> <p>Auger, Nathalie; Gilbert, Nicolas L; Naimi, Ashley I; Kaufman, Jay S</p> <p>2014-01-01</p> <p>Background: Fetuses-at-risk denominators are commonly used in research on preterm stillbirth, but applications to postnatal outcomes such as preterm infant mortality are controversial. We evaluated whether biased associations between maternal risk factors and preterm infant mortality caused by stratification by preterm birth could be avoided using fetuses-at-risk risk ratios. Methods: Data included 3 277 570 births drawn from the linked live birth-death file for Canada from 1990 through 2005. We used maternal <span class="hlt">age</span> as the risk factor, and estimated the association with stillbirth, early neonatal, late neonatal and postneonatal mortality by gestational interval (22–24, 25–27, 28–31, 32–36, ≥37 weeks). Models were run using (i) log-binomial regression stratified by preterm gestational <span class="hlt">age</span>, and (ii) unstratified log-binomial regression using fetuses-at-risk denominators. Results: Extremes of maternal <span class="hlt">age</span> were associated with higher mortality among term births. Among preterm births, the stratified model suggested a protective, null or attenuated association of extremes of maternal <span class="hlt">age</span> with stillbirth, early, late and post neonatal mortality. The unstratified fetuses-at-risk model, however, resulted in the expected higher risk of mortality at extremes of maternal <span class="hlt">age</span> for all outcomes. Conclusions: Fetuses-at-risk regression can avoid paradoxical associations between maternal exposures and mortality of infants born early in gestation, caused by preterm birth stratification bias. The fetuses-at-risk approach can be extended through the first year of life, or potentially beyond, depending on the outcome and presence of unmeasured confounders associated with preterm birth.

M.</p> <p>2016-12-01</p> <p>Metamorphic core complexes (Mccs) within the western U.S. record a history of Cenozoic ductile and brittle extensional deformation, metamorphism, and magmatism, and exhumation within the footwall of high-angle Basin and Range normal faults. Documenting these histories within Mccs have been topics of research for over 40 years, yet there remains disagreement about: 1) whether the detachment fault formed and moved at low angles or initiated at high angles and rotated to a low angle; 2) whether brittle and ductile extensional deformation were linked in space and time; and 3) the temporal relationship of both modes of <span class="hlt">extension</span> to the development of the detachment fault. The northern Snake Range metamorphic core complex (NSR), Nevada has been central to this debate. To address these issues, we report new U/Pb dates from zircon in deformed and undeformed rhyolite dikes emplaced into ductilely thinned and horizontally stretched lower plate rocks that provide tight bounds on the timing of ductile <span class="hlt">extension</span> at between 38.2 ± 0.3 Ma and 22.50 ± 0.36 Ma. The maximum <span class="hlt">age</span> constraint is from the Northern dike swarm (NDS), which was emplaced in the northwest part of the range pre- to syn-tectonic with ductile <span class="hlt">extension</span>. The minimum <span class="hlt">age</span> constraint is from the Silver Creek dike swarm (SDS) that was emplaced in the southern part of the range post ductile extensional deformation. Our field observations, petrography, and U/Pb zircon <span class="hlt">ages</span> on the dikes combined with published data on the geology and kinematics of <span class="hlt">extension</span>, moderate and low temperature thermochronology on lower plate rocks, and <span class="hlt">age</span> and faulting histories of Cenozoic sedimentary basins adjacent to the NSR are interpreted as recording an episode of localized upper crustal brittle <span class="hlt">extension</span> during the Eocene that drove upward ductile extensional flow of hot middle crustal rocks from beneath the NSR detachment soon after, or simultaneous with, emplacement of the NDS.

Our testable model indicates that: From 60-45 Ma SOAM moved southward ca.200 km with respect to NOAM as CARIB squeezed into the Atlantic forcing the Yucatan and Grenada basins to open. Since 45 Ma CARIB has moved only east carrying fragments of the Caribbean Great Arc that had struck the west coast of SOAM at ca.70 Ma and shearing the passive margin of SOAM in a ca.250 km wide right-lateral transform PBZ between the thick continental lithosphere of SOAM and the thick oceanic plateau lithosphere of CARIB. Pull-aparts in the PBZ include the Falcon, Cariaco and Gulf of Paria basins and flower structure thrust belts include, the Serrania del Interior, Villa de Cura, Araya-Paria peninsula and the Northern Range of Trinidad. These thrust belts generated the loads that formed the East Venezuelan 150 km wide foreland basin. This model requires that: (1) all igneous and high P/T metamorphic <span class="hlt">ages</span> in the thrust belts of Venezuela were acquired at or before ca. 70 Ma when the Great Arc of the Caribbean struck the west coast of SOAM; (2) Younger igneous <span class="hlt">ages</span> in the northern part of the PBZ represent fragments of the southern end of the Lesser Antillean arc dragged into the PBZ as the arc slid by; and (3) Deformation in the PBZ began no earlier than the local time of passage of the southern end of the Lesser Antillean arc except in the Gulf of Paria region where halokinesis began earlier. Collision of the Panama arc (ca.7Ma) caused shortening on the west coast of SOAM and 70 km of northward escape of the triangular Maracaibo prism bounded by the Bocono and Santa Marta strike-slip faults and by a deep lithospheric-scale thrust. Restoring the Maracaibo prism aligns the Cuisa and Oca faults with the CARIB-SOAM east-west trending PBZ.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://hdl.handle.net/2060/19890004122','NASA-TRS'); return false;" href="http://hdl.handle.net/2060/19890004122"><span>Evaluation of coated columbium <span class="hlt">test</span> panels having application to a secondary nozzle <span class="hlt">extension</span> for the RL10 rocket engine system, parts 1 and 2</span></a></p> <p><a target="_blank" href="http://ntrs.nasa.gov/search.jsp">NASA Technical Reports Server (NTRS)</a></p> <p>Murphy, Kenneth S.; Castro, Joaquin H.</p> <p>1988-01-01</p> <p>The activity performed on the screening and evaluation of various coatings for application on columbium alloy <span class="hlt">test</span> panels representative of a radiation-cooled nozzle <span class="hlt">extension</span> for the RL10 rocket engine is summarized.

The aim of this study is to develop a model of the construct that is focused on the individual, including different elements of people's lives that have the potential to be modified by intervention programs. Moreover, the paper examines the contributions of active <span class="hlt">ageing</span> to life satisfaction, as well as the possible predictive role of coping styles on active <span class="hlt">ageing</span>. For this purpose, a representative sample of 404 Galician (Spain) community-dwelling older adults (<span class="hlt">aged</span> ≥60 years) were interviewed using a structured survey.

The model comprises status variables (related to physical, psychological, and social health) as well as different types of activities, called processual variables. This model is <span class="hlt">tested</span> using partial least squares (PLS) regression. The findings show that active <span class="hlt">ageing</span> is a fourth-order, formative construct. In addition, PLS analyses indicate that active <span class="hlt">ageing</span> has a moderate and positive path on life satisfaction and that coping styles may predict active <span class="hlt">ageing</span>.

A.</p> <p>2004-12-01</p> <p>Polygonal features with characteristic dimensions of 100 +/- 30 m, bounded by cracks, are commonly observed on the martian northern plains. These features have previously been attributed to thermal cracking, in direct analogy to ice-wedge polygons in terrestrial polar regions. Polygons were mapped in the northern mid latitudes (30 to 65 N) using all Mars Orbiter Camera (MOC) narrow-angle images (5 m per pixel) from September 1997 through September 2003. Three fourths of MOC images showing polygons are centered in western Utopia Planitia (40 to 50 N; 258 to 288 W). This region, notable for its dense concentration of polygonal terrain, is otherwise non-unique in its mapped geology, topography, gravity, or albedo. Previous authors have suggested that this concentration of polygons indicates the presence of a generally continuous ice-rich mantle. Ice stability models, neutron spectroscopy data, and the common occurrence of thermokarst indicate that the ice is concentrated below 1 m depth and is currently subliming. The MOC images show 687 craters, with diameters between 100 m and 4 km, on polygonal terrain. The size-frequency distribution of these craters larger than 1 km is concordant with the Barlow distribution for craters larger than 8 km in western Utopia, indicating preservation of a late Hesperian crater population. Approximately 20 of the 687 craters on polygonal terrain postdate the adjacent polygonal cracks, indicating Amazonian-<span class="hlt">age</span> deposition or activation of the ice-rich layer. The size-frequency distribution of craters on polygonal terrain shows a marked deficiency of craters smaller than 1 km, suggestive of mantling. Some such craters with diameters between 460 m and 1.1 km are buried to their rims by polygonal terrain; below this range all rims are buried, and above all rims are exposed. Based on the MOLA-derived relationship between rim height and crater diameter, this range indicates that the ice-rich layer is locally 30 to 40 m thick.

The work includes a review of relevant literature as well as hands-on experimental verification of inspection capabilities. As NPPs consider applying for second, or subsequent, license renewal (SLR) to extend their operating period from 60 years to 80 years, it important to understand how the materials installed in plant systems and components will <span class="hlt">age</span> during that time and develop <span class="hlt">aging</span> management programs (AMPs) to assure continued safe operation under normal and design basis events (DBE). Normal component and system <span class="hlt">tests</span> typically confirm the cables can perform their normal operational function. The focus of the cable <span class="hlt">test</span> program is directed toward the more demanding challenge of assuring the cable function under accident or DBE. Most utilities already have a program associated with their first life <span class="hlt">extension</span> from 40 to 60 years. Regrettably, there is neither a clear guideline nor a single NDE that can assure cable function and integrity for all cables. Thankfully, however, practical implementation of a broad range of <span class="hlt">tests</span> allows utilities to develop a practical program that assures cable function to a high degree. The industry has adopted 50% elongation at break (EAB) relative to the un-<span class="hlt">aged</span> cable condition as the acceptability standard. All <span class="hlt">tests</span> are benchmarked against the cable EAB <span class="hlt">test</span>. EAB is a destructive <span class="hlt">test</span> so the <span class="hlt">test</span> programs must apply an array of other NDE <span class="hlt">tests</span> to assure or infer the overall set of cable’s system integrity. These cable NDE programs vary in rigor and methodology. As the industry gains experience with the efficacy of these programs, it is expected that implementation practice will converge to a more common approach.

Given the prevalence of recovery of pedal elements in isolation, it is critical that methods exist to facilitate the estimation of <span class="hlt">age</span> from this anatomical region and that those methods be <span class="hlt">tested</span> to ensure they are reliable, repeatable and statistically robust. A study was carried out to determine the validity of using the Whitaker method of <span class="hlt">age</span> estimation from the bones of the foot as a tool in forensic <span class="hlt">age</span> estimation within a modern Scottish population. Two-hundred and sixty radiographs from individuals <span class="hlt">aged</span> between birth and 18 years were assessed according to the Whitaker method; the results were compared with chronological <span class="hlt">age</span>. The results of this study suggest that the method of Whitaker et al. is highly unlikely to estimate the <span class="hlt">age</span> of females below 16 years of <span class="hlt">age</span> or males below 18 years of <span class="hlt">age</span> correctly. When the methodology was altered to correspond with best practice principles of <span class="hlt">age</span> estimation, the estimated <span class="hlt">age</span> ranges were found to be too wide to be of practical value in forensic <span class="hlt">age</span> estimation.

Sixty participants (<span class="hlt">aged</span> 28 to 71 years) were divided into young, middle-<span class="hlt">aged</span> and old groups of both genders. Clinical stress <span class="hlt">test</span> was performed by stationary cycle ergometer (CEload). Peak oxygen uptake (VO2peak), heart rate and lactate concentration were measured using maximal TMload <span class="hlt">test</span>. Isometric strength and EMG-activity of upper and lower extremities were measured before and after TMload. VO2peak of TMload correlated significantly with TMload exercise time (ET) in all other groups (r=0.67 to 0.91 and p ≤ 0.05 to p<0.001) except old men. Leg <span class="hlt">extension</span> force decreased (p ≤ 0.05 to p<0.001) after TMload in all groups, grip force in young groups (p ≤ 0.05), while plantar flexion force and all EMGs remained unchanged. In men VO2peak explained 81% and in women VO2peak and <span class="hlt">age</span> explained 87% of the total variation of the TMload ET. In conclusion, ET of TMload is associated with high VO2peak, but not with muscle strength or its changes during the loading. The present load carrying walking <span class="hlt">test</span> may be used for <span class="hlt">testing</span> workers with heavy loading in their occupation or in rehabilitation purposes.

Overlap between these two methods of assessing complex cognition in older <span class="hlt">age</span> remains unclear. Such overlap could be investigated using inter-<span class="hlt">test</span> correlations alone, as in previous studies, but this would be enhanced by ascertaining whether frontal <span class="hlt">test</span> performance and gf share neurobiological variance. To this end, we examined relationships between gf and 6 frontal <span class="hlt">tests</span> (Tower, Self-Ordered Pointing, Simon, Moral Dilemmas, Reversal Learning and Faux Pas <span class="hlt">tests</span>) in 90 healthy males, <span class="hlt">aged</span> ~ 73 years.

Some frontal <span class="hlt">test</span> scores also exhibited shared variance after controlling for gf. Principal component analysis of <span class="hlt">test</span> scores identified units of gf-common and gf-independent variance. The former was associated with variance in the left dorsolateral (DL) and anterior cingulate (AC) regions, and the latter with variance in the right DL and AC regions. Thus, we identify two biologically-meaningful components of variance in complex cognitive performance in older <span class="hlt">age</span> and suggest that <span class="hlt">age</span>-related changes to DL and AC have the greatest cognitive impact.

The present state of knowledge is based on using injury outcomes and biomechanical metrics from post-mortem human subject (PMHS) and mechanical records from dummy <span class="hlt">tests</span>. Data from these models are combined to develop dummy injury assessment risk curves (IARCs)/dummy injury assessment risk values (IARVs). This simple substitution approach involves duplicating dummy metrics for PMHS <span class="hlt">tested</span> under similar conditions and pairing with PMHS injury outcomes. It does not directly account for the <span class="hlt">age</span> of each specimen <span class="hlt">tested</span> in the PMHS group.

The <span class="hlt">age</span>-infusion methodology presented in this perspective article accommodates for an annual rate factor that modifies the dummy injury risk assessment responses to account for the <span class="hlt">age</span> of the PMHS that the injury data were based on.

The present state of knowledge is based on using injury outcomes and biomechanical metrics from post-mortem human subject (PMHS) and mechanical records from dummy <span class="hlt">tests</span>. Data from these models are combined to develop dummy injury assessment risk curves (IARCs)/dummy injury assessment risk values (IARVs). This simple substitution approach involves duplicating dummy metrics for PMHS <span class="hlt">tested</span> under similar conditions and pairing with PMHS injury outcomes. It does not directly account for the <span class="hlt">age</span> of each specimen <span class="hlt">tested</span> in the PMHS group. Current substitution methods for injury risk assessments use <span class="hlt">age</span> as a covariate and dummy metrics (e.g., accelerations) are not modified so that <span class="hlt">age</span> can be directly included in the model. The <span class="hlt">age</span>-infusion methodology presented in this perspective article accommodates for an annual rate factor that modifies the dummy injury risk assessment responses to account for the <span class="hlt">age</span> of the PMHS that the injury data were based on.

The aim was to determine the impact of <span class="hlt">age</span> on the safety, tolerability and efficacy of long-term treatment with fesoterodine 8 mg in subjects with OAB syndrome. This was a pooled analysis of two identically designed open-label <span class="hlt">extensions</span> of 12-week, randomized, double-blind, placebo-controlled studies. The setting was urology and general practice offices. Subjects who participated in the 12-week, double-blind studies and opted to continue long-term, open-label treatment with fesoterodine were included. Subjects were initiated on fesoterodine 8 mg/day at open-label baseline. After 1 month, subjects could elect dose reduction to 4 mg/day and subsequent re-escalation to 8 mg; each was permitted once annually. Maximal duration of open-label treatment ranged from 24 to 36 months.

This study extends previous work on the relations between <span class="hlt">tests</span> and language samples to a new population—school-<span class="hlt">age</span> bilingual speakers with primary language impairment—and considers the clinical implications for bilingual assessment. Method Fifty-one bilingual children with primary language impairment completed narrative language samples and standardized language <span class="hlt">tests</span> in English and Spanish. Children were separated into younger (<span class="hlt">ages</span> 5;6 [years;months]–8;11) and older (<span class="hlt">ages</span> 9;0–11;2) groups. Analysis included correlations with <span class="hlt">age</span> and partial correlations between language sample measures and <span class="hlt">test</span> scores in each language. Results Within the younger group, positive correlations with large effect sizes indicated convergence between <span class="hlt">test</span> scores and microstructural language sample measures in both Spanish and English. There were minimal correlations in the older group for either language. <span class="hlt">Age</span> related to English but not Spanish measures. Conclusions <span class="hlt">Tests</span> and language samples complement each other in assessment. Wordless picture-book narratives may be more appropriate for <span class="hlt">ages</span> 5–8 than for older children. We discuss clinical implications, including a case example of a bilingual child with primary language impairment, to illustrate how to synthesize information from these tools in assessment.

Ilia were scored for five features: transverse organization, surface texture, microporosity, macroporosity, and apical changes, which combined for a composite score. The results indicated that all features and the composite score were positively correlated with known <span class="hlt">age</span>. Composite scores were significantly different between the sexes, suggesting that males and females should be treated separately.

In the study described herein, new physical examination <span class="hlt">tests</span> for LS and LI were devised and evaluated for their validity. The <span class="hlt">test</span> for LS was designated "low midline sill sign", and that for LI was designated "interspinous gap change" during lumbar flexion-<span class="hlt">extension</span> motion. The validity of the low midline sill sign was evaluated in 96 patients with low back or lumbar radicular pain. Validity of the interspinous gap change during lumbar flexion-<span class="hlt">extension</span> motion was evaluated in 73 patients with low back or lumbar radicular pain. The sensitivity, specificity, and positive and negative predictive values of the two <span class="hlt">tests</span> were also investigated. The sensitivity and specificity of the low midline sill sign for LS were 81.3% and 89.1%, respectively.

In a within-participants study (n = 12), participants performed three lifting techniques--free style, stoop and squat lifting from knee to waist level--using the same dynamic functional capacity evaluation lifting <span class="hlt">test</span> to assess MAWL and to calculate low back and knee kinetics. We assessed which knee and back kinetic parameters increased with the load mass lifted, and whether the magnitudes of the kinetic parameters were consistent across techniques when lifting MAWL. MAWL was significantly different between techniques (p = 0.03). The peak lumbosacral <span class="hlt">extension</span> moment met both criteria: it had the highest association with the load masses lifted (r > 0.9) and was most consistent between the three techniques when lifting MAWL (ICC = 0.87). In conclusion, MAWL reflects the lumbosacral <span class="hlt">extension</span> moment across free style, stoop and squat lifting in healthy young males, but the relation between the load mass lifted and lumbosacral <span class="hlt">extension</span> moment is different between techniques. <span class="hlt">Tests</span> of maximum acceptable weight of lift (MAWL) from knee to waist height are used to assess work capacity of individuals with low-back disorders.

Cross-sectional. University-based research laboratory. 331 healthy subjects separated into six groups according to <span class="hlt">age</span>: G1, 18 to 28 years; G2, 29 to 39 years; G3, 40 to 50 years; G4, 51 to 61 years; G5, 62 to 72 years and; G6, 73 to 83 years. Two ISWTs were performed and participants were permitted to run and to exceed 12 levels during the <span class="hlt">test</span>, if necessary. Heart rate (HR) and symptoms of dyspnoea and fatigue were recorded before and after the <span class="hlt">test</span>, and the percentage of <span class="hlt">age</span>-predicted maximal HR (HRmax) was calculated. Maximal effort was defined as HRmax >90% of <span class="hlt">age</span>-predicted HRmax. Almost 31% of the subjects exceeded 12 levels in the ISWT. At the end of the <span class="hlt">test</span>, all groups presented a median [interquartile range] HR greater than 90% of HRmax (G1: 100 [95 to 104]; G2: 100 [96 to 105]; G3: 103 [97 to 108]; G4: 99 [91 to 106]; G5: 96 [87 to 106] and G6: 96 [91 to 109]% HRmax). Regarding symptoms, all groups showed higher values after the <span class="hlt">test</span> (P<0.05). A multiple logistic regression analysis identified female gender, older <span class="hlt">age</span> and a lower HR before the <span class="hlt">test</span> as determinants of not achieving 90% of HRmax at the end of the <span class="hlt">test</span>. The ISWT requires maximal effort in healthy individuals, but for that it is necessary to extend the <span class="hlt">test</span> beyond twelve levels. Female gender, older <span class="hlt">age</span> and lower heart rate before the <span class="hlt">test</span> are the determinants of not reaching maximal effort.

The primary objective of the study was to identify in nursing home women a variable extracted from instrumented TUG (iTUG) that is the best predictor of <span class="hlt">age</span>. The secondary objective was to assess whether this variable is associated with the results of the isometric knee <span class="hlt">extension</span> peak torque (IKEPT); lower limb strength measured by the 30-s chair stand <span class="hlt">test</span> (30sCST), and walking capacity measured by the 6-min walk <span class="hlt">test</span> (6MWT). Twenty-six women (mean ± SD: <span class="hlt">age</span>-85.8 ± 3.6 years; body weight-59.4 ± 12.3 kg; body height-151.0 ± 7.3 cm; BMI-26.0 ± 4.9 kg/m(2)) performed iTUG (while wearing a body-fixed inertial sensor) and functional <span class="hlt">tests</span>. Total iTUG performance time significantly correlated with <span class="hlt">age</span> (r = 0.484; p < 0.05), 30sCST (r = -0.593; p < 0.01), and 6MWT (r = -0.747; p < 0.001) but not with absolute nor relative IKEPT (p > 0.05). Additionally, the subjects' <span class="hlt">age</span> correlated with 30sCST (r = -0.422; p < 0.05), 6MWT (r = -0.482; p < 0.05), IKEPT (r = -0.392; p < 0.05) and IKEPT/FFM (r = -0.407; p < 0.05). Five out of 16 analyzed iTUG variables were significantly related to <span class="hlt">age</span>, and multiple regression analysis showed the best correlation with the sit-to-stand vertical acceleration range (STSVAR) (r(2) = 0.430; SEE = 3.041; β = -0.544 ± 0.245; B = -1.204 ± 0.543; p < 0.05).

The obtained results suggest that in the oldest old group of nursing home women an <span class="hlt">age</span>-related decline in TUG performance is mainly associated with a reduction of "explosive" strength of lower limb muscles.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.osti.gov/scitech/servlets/purl/10152475','SCIGOV-STC'); return false;" href="http://www.osti.gov/scitech/servlets/purl/10152475"><span><span class="hlt">Aging</span>, Loss-of-Coolant Accident (LOCA), and high potential <span class="hlt">testing</span> of damaged cables</span></a></p> <p><a target="_blank" href="http://www.osti.gov/scitech">SciTech Connect</a></p> <p>Vigil, R.A.; Jacobus, M.J.</p> <p>1994-04-01</p> <p>Experiments were conducted to assess the effects of high potential <span class="hlt">testing</span> of cables and to assess the survivability of <span class="hlt">aged</span> and damaged cables under Loss-of-Coolant Accident (LOCA) conditions. High potential <span class="hlt">testing</span> at 240 Vdc/mil on undamaged cables suggested that no damage was incurred on the selected virgin cables. During <span class="hlt">aging</span> and LOCA <span class="hlt">testing</span>, Okonite ethylene propylene rubber (EPR) cables with a bonded jacket experienced unexpected failures.

Comparisons of P13 / N23 latency, amplitude and threshold response curves have been used to compare pathologic groups to normal controls. Appropriate characterization of these etiologies requires normative data across the frequency spectrum and <span class="hlt">age</span> range. Purpose The objective of the current study was to <span class="hlt">test</span> the hypothesis that significant changes in VEMP responses occur as a function of increased <span class="hlt">age</span> across all <span class="hlt">test</span> stimuli as well as characterize the VEMP threshold response curve across <span class="hlt">age</span>. Research Design This project incorporated a prospective study design using a sample of convenience. Openly recruited subjects were assigned to groups according to <span class="hlt">age</span>. Study Sample Forty-six normal controls ranging between 20 and 76 years of <span class="hlt">age</span> participated in the study. Participants were separated by decade into 5 <span class="hlt">age</span> categories from 20 to 60 plus years. Normal participants were characterized by having normal hearing sensitivity, no history of neurologic or balance/dizziness involvement and negative results on a direct office vestibular examination. Intervention VEMP responses were measured at threshold to click and 250, 500, 750, and 1000 Hz tone burst stimuli and at a suprathreshold level to 500 Hz toneburst stimuli at123 dBSPL.

Bramwell</p> <p>1999-04-01</p> <p>This report describes four sets of <span class="hlt">tests</span> sponsored by the U.S. Nuclear Regulatory Commission and conducted by the Idaho National Engineering and Environmental Laboratory. The <span class="hlt">tests</span> support research addressing the need to provide assurance that motor-operated valves are able to perform their intended safety function, usually to open or close against specified (design basis) flow and pressure loads. One of the parameters that affects a gate valve's operability is the friction between the disc seats and the valve body seats. In most gate valves, these surfaces are hardfaced with Stellite 6, a cobalt-based alloy. The <span class="hlt">tests</span> described in this report investigate the changes that occur in the friction as the Stellite 6 surfaces develop an oxide film as they <span class="hlt">age</span>. Stellite 6 specimens were <span class="hlt">aged</span> in a corrosion autoclave, the oxide films were examined and characterized, and the specimens were subjected to friction <span class="hlt">testing</span> in a friction autoclave. A very thin oxide film formed after only a fe w days of natural <span class="hlt">aging</span>. Even a very thin oxide film caused an increase in friction. The surface structure of the oxide film was dominated by a hard crystalline structure, such that the friction response was analogous to rubbing two pieces of sandpaper together. In the limited data provided by naturally <span class="hlt">aged</span> specimens (78 days maximum exposure, very thin oxide films), the friction increased with greater <span class="hlt">aging</span> time, approaching an as-yet-undetermined plateau. Although the thickness of the oxide film increased with greater <span class="hlt">aging</span> time, the mechanical properties of the oxide film (larger granules with greater <span class="hlt">aging</span> time) appeared to play a greater role in the friction response. Friction <span class="hlt">testing</span> of specimens subjected to simulated in-service <span class="hlt">testing</span> strokes at intervals during the <span class="hlt">aging</span> process showed only a slight decrease in friction, compared to other specimens.

A total of 2084 community dwelling older adults from wave I and II were recruited through a multistage random sampling method.

Forensic <span class="hlt">age</span> inference was initially based on morphological inspection or radiography and only later began to adopt molecular approaches. However, a lack of accuracy or technical problems hampered the introduction of these DNA-based methodologies in casework analysis. A turning point occurred when the epigenetic signature of DNA methylation was observed to gradually change during an individual´s lifespan. In the last four years, the number of publications reporting DNA methylation <span class="hlt">age</span>-correlated changes has gradually risen and the forensic community now has a range of <span class="hlt">age</span> methylation <span class="hlt">tests</span> applicable to forensic casework. Most forensic <span class="hlt">age</span> predictor models have been developed based on blood DNA samples, but additional tissues are now also being explored. This review assesses the most widely adopted genes harboring methylation sites, detection technologies, statistical <span class="hlt">age</span>-predictive analyses, and potential causes of variation in <span class="hlt">age</span> estimates. Despite the need for further work to improve predictive accuracy and establishing a broader range of tissues for which <span class="hlt">tests</span> can analyze the most appropriate methylation sites, several forensic <span class="hlt">age</span> predictors have now been reported that provide consistency in their prediction accuracies (predictive error of ±4 years); this makes them compelling tools with the potential to contribute key information to help guide criminal investigations.

Six healthy males participated in this study. They performed isometric contractions at 90° and 20° of knee flexion, gradually increasing to maximum effort. For the calculation of the actual knee-joint moment and the joint moment relative to the knee-joint center, determined using the external marker, two free body diagrams were used of the Cybex arm and the lower leg segment system. In the first free body diagram, the mean center of the circular profiles of the femoral epicondyles was used as the knee-joint center, whereas in the second diagram, the joint center was assumed to coincide with the external marker.

Six healthy males participated in this study. They performed isometric contractions at 90° and 20° of knee flexion, gradually increasing to maximum effort. For the calculation of the actual knee-joint moment and the joint moment relative to the knee-joint center, determined using the external marker, two free body diagrams were used of the Cybex arm and the lower leg segment system. In the first free body diagram, the mean center of the circular profiles of the femoral epicondyles was used as the knee-joint center, whereas in the second diagram, the joint center was assumed to coincide with the external marker. Then, the calculated knee-joint moments were compared with those measured by the dynamometer. The results indicate that 1) the actual knee-joint moment was different from the dynamometer recorded moment (difference ranged between 1.9% and 4.3%) and the moment calculated using the skin marker (difference ranged between 2.5% and 3%), and 2) during isometric knee <span class="hlt">extension</span>, the internal knee angle changed significantly from rest to the maximum contraction state by about 19°.

The structural architecture of the lower- and mid-crustal at the onset of <span class="hlt">extension</span> may be complex due to lithologic variation resulting from structural juxtaposition of pre-arc lithologies, intrusion of plutons, and local partial melting. Additional complexity is introduced by the dynamic nature of arcs. Thus, robust <span class="hlt">ages</span> for deformation, metamorphism, intrusion, and partial melting are essential for unraveling arc evolution and discerning the role of arc plutonism and metamorphism in strain localization during both contraction and <span class="hlt">extension</span>. Eclogite and granulite facies metamorphic minerals indicate that Mesozoic arc crust in Fiordland was ≥ 50 km thick ca. 130 Ma prior to extensional collapse. This mid- to lower-crust records a history of mafic to intermediate magmatism, high-grade metamorphism, lower crustal melting, and the formation of extensional detachments that border eclogite- and granulite-cored gneiss domes. U-Pb zircon and Sm-Nd garnet <span class="hlt">ages</span> indicate that intrusion of voluminous plutons, including the Western Fiordland Orthogneiss (WFO), and subsequent metamorphism occurred sequentially from north to south. Pluton emplacement occurred at 0.6-1.1 GPa in the north to 1.0-1.2 GPa in the south. In northern Fiordland [Milford Sound], intrusion of 135-128 Ma gabbroic magma was followed by 0.6-1.1 GPa 2-pyroxene granulite metamorphism at 126-135 Ma, and then 1.2-1.4 GPa garnet granulite metamorphism and partial melting ca. 126-123 Ma. To the south, WFO plutons have a similar history from north to south: the low-P 125-120.1 Ma Worsley was metamorphosed to garnet granulite at 1.2-1.4 GPa, ca. 115 Ma; the low-P ca. 120 Ma Misty was metamorphosed to garnet granulite at 1.2 GPa, ca. 115 Ma; the high-P 117.8-113.2 Ma Malaspina was metamorphosed to garnet granulite at 1.0-1.4 GPa, ca. 113 Ma along Doubtful Sound and 111.9±1.6 Ma to the south on</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('https://www.ncbi.nlm.nih.gov/pubmed/27486430','PUBMED'); return false;" href="https://www.ncbi.nlm.nih.gov/pubmed/27486430"><span><span class="hlt">Aging</span> Increases Compensatory Saccade Amplitude in the Video Head Impulse <span class="hlt">Test</span>.</span></a></p> <p><a target="_blank" href="https://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pubmed">PubMed</a></p> <p>Anson, Eric R; Bigelow, Robin T; Carey, John P; Xue, Quan-Li; Studenski, Stephanie; Schubert, Michael C; Weber, Konrad P; Agrawal, Yuri</p> <p>2016-01-01</p> <p>Rotational vestibular function declines with <span class="hlt">age</span> resulting in saccades as a compensatory mechanism to improve impaired gaze stability.

Horizontal VOR gain was measured in 243 participants <span class="hlt">age</span> 27-93 from the Baltimore Longitudinal Study of <span class="hlt">Aging</span> using video head impulse <span class="hlt">testing</span>. Latency and amplitude of the first saccade (either covert - occurring during head impulse, or overt - occurring following head impulse) were measured for head impulses with compensatory saccades (n = 2230 head impulses). The relationship between <span class="hlt">age</span> and saccade latency, as well as the relationship between <span class="hlt">age</span> and saccade amplitude, were evaluated using regression analyses adjusting for VOR gain, gender, and race. Older adults (mean <span class="hlt">age</span> 75.9) made significantly larger compensatory saccades relative to younger adults (mean <span class="hlt">age</span> 45.0).

Raman lidar observations performed at three stations of EARLINET (Athens, Thessaloniki and Istanbul), provided clear ash signatures within certain layers, although ash was sometimes mixed with mineral dust advected from the Saharan region. AERONET columnar measurements did not indicate the presence of ash over the area for that period, although they did for the dust particles. This was further investigated and confirmed by simulations of the ash trajectories by the FLEXPART model and the BSC-DREAM8b dust model. Good agreement was found between simulated and observed geometrical characteristics of the ash and dust layers, respectively. Ash particles were observed over the lidar stations after 6-7-days transport from the volcanic source at height ranges between approximately 1.5 and 6 km. Mean ash particle layer thickness ranged between 1.5 and 2.5 km and the corresponding aerosol optical depth (AOD) was of the order of 0.12-0.06 at 355 nm and of 0.04-0.05 at 532 nm. Inside the ash layers, the lidar ratios (LR) ranged between 55 and 67 sr at 355 nm and 76-89 sr at 532 nm, while the particle linear depolarization ratio ranged between 10 and 25%.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('https://www.ncbi.nlm.nih.gov/pubmed/27001718','PUBMED'); return false;" href="https://www.ncbi.nlm.nih.gov/pubmed/27001718"><span>Odor-Specific Loss of Smell Sensitivity with <span class="hlt">Age</span> as Revealed by the Specific Sensitivity <span class="hlt">Test</span>.</span></a></p> <p><a target="_blank" href="https://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pubmed">PubMed</a></p> <p>Seow, Yi-Xin; Ong, Peter K C; Huang, Dejian</p> <p>2016-07-01</p> <p>The perception of odor mixtures plays an important role in human food intake, behavior, and emotions. Decline of smell acuity with normal <span class="hlt">aging</span> could impact food perception and preferences at various <span class="hlt">ages</span>. However, since the landmark Smell Survey by National Geographic, little has been elucidated on differences in the onset and extent of loss in olfactory sensitivity toward single odorants.

Subjects of Chinese descent in Singapore (186 women, 95 men), <span class="hlt">aged</span> 21-80 years, were assessed for olfactory sensitivity of 10 odorants from various odor groups. Notably, subjects in their 70s required 179 times concentration of rose-like odorant (2-phenylethanol) than subjects in the 20s, while thresholds for onion-like 2-methyloxolane-3-thiol only differed by 3 times between the <span class="hlt">age</span> groups. In addition, identification rate for 2-phenylethanol was negatively correlated with <span class="hlt">age</span> throughout adult life whereas mushroom-like oct-1-en-3-ol was equally identified by subjects across all <span class="hlt">ages</span>. Our results demonstrated the girth of differentiated olfactory loss due to normal <span class="hlt">ageing</span>, which potentially affect overall perception and preferences of odor mixtures with <span class="hlt">age</span>. © The Author 2016.

Factors promoting well-being at work need to be identified, which would enable targeting interventions and development in nursing work in an appropriate manner. Due to dissimilarity of many areas of nursing work and unique features of every <span class="hlt">age</span> group, specialized and aligned scales are needed. The aim of this article is to describe a study to develop and <span class="hlt">test</span> the psychometric properties of the Dignity and Respect in <span class="hlt">Ageing</span> Nurses' Work Scale (DRANWS). A sample of 328 <span class="hlt">ageing</span> Finnish hospital nurses in the first phase (response rate 55%) and 285 nurses in the second phase (response rate 48%) responded to the scale. Content validity was assessed by expert evaluation. Exploratory factor analysis was used to assess construct validity. Reliability (internal consistency) was assessed by Cronbach's alpha coefficient. The DRANWS consists of 72 items and three dimensions: (1) nurse-nurse interaction (cohesion, feeling of freedom in work community, giving and receiving assistance and support, nurses' status at work, perceiving one's work as meaningful, being together with other nurses, nurses working in pairs), (2) nurse-patient interaction (patient satisfaction, well-conducted nursing, encountering patients and helping them) and (3) nursing-centredness (provision of good care to patients, putting the patient first, appreciation of nursing). Cronbach's alphas ranged from 0.74 to 0.96 in the first phase and from 0.79 to 0.98 in the second phase, demonstrating the internal consistency of scale to be high. Content validity was good based on expert evaluations. Construct validity of the scale was also very good based on factor analysis. In conclusion, the DRANWS is a reliable and valid scale to measure well-being at work of <span class="hlt">ageing</span> hospital nurses focusing on dignity and respect. © 2011 The Authors.

Overall, similar <span class="hlt">aging</span> trends are observed for softwood and cane fiberboard samples, with a few differences. Some softwood fiberboard properties tend to degrade faster in some environments, while some cane fiberboard properties degrade faster in the two most aggressive environments. As a result, it is premature to assume both materials will <span class="hlt">age</span> at the same rates, and the preliminary <span class="hlt">aging</span> models developed for cane fiberboard might not apply to softwood fiberboard.

We hypothesized that there would be a reduced microvascular Po2 (Po2m) in the <span class="hlt">testes</span> from <span class="hlt">aged</span> rats, and this reduced Po2m would be associated with impaired vasomotor control in isolated resistance arterioles. In addition, given the positive effect of exercise on microvascular Po2 and arteriolar function, we further hypothesized that there would be an enhanced Po2m in the <span class="hlt">testes</span> from <span class="hlt">aged</span> animals after aerobic exercise training. Testicular Po2m was measured in vivo via phosphorescence quenching in young and <span class="hlt">aged</span> sedentary (SED) and exercise-trained (ET; 15 m/min treadmill walking, 15-degree incline, 5 days/wk for 10 wk) male Fischer-344 rats. Vasoconstriction to α-adrenergic [norepinephrine (NE) and phenylephrine (PE)] and myogenic stimuli in testicular arterioles was assessed in vitro. In the SED animals, testicular Po2m was reduced by ∼50% with old <span class="hlt">age</span> (<span class="hlt">aged</span> SED 11.8 ± 1.9 vs. young SED 22.1 ± 1.1 mmHg; P = 0.0001). Contrary to our hypothesis, exercise training did not alter Po2m in the <span class="hlt">aged</span> group and reduced testicular Po2m in the young animals, abolishing <span class="hlt">age</span>-related differences (young ET, 10.0 ± 0.8 vs. <span class="hlt">aged</span> ET, 10.7 ± 0.9 mmHg; P = 0.37). Vasoconstrictor responsiveness to NE and PE was diminished in <span class="hlt">aged</span> compared with young (NE: young SED, 58 ± 2 vs. <span class="hlt">aged</span> SED, 47 ± 2%; P = 0.001) (PE: young SED, 51 ± 3 vs. <span class="hlt">aged</span> SED, 36 ± 5%; P = 0.008).

Objetivo: determinar la validez del ángulo lumbo-horizontal en flexión y la distancia alcanzada en el <span class="hlt">test</span> sitand- reach como criterio de extensibilidad isquiosural en mujeres mayores. Metodología: un total de 120 mujeres mayores realizaron aleatoriamente los <span class="hlt">test</span> de elevación de pierna recta (EPR) con ambas piernas y el <span class="hlt">test</span> sit-and-reach (SR). En este último se valoró la distancia alcanzada y la disposición del raquis lumbo-sacro (L-Hfx) al alcanzar la posición de máxima flexión del tronco. Resultados y discusión: los valores medios en el EPR fueron 81,70 ± 13,83º y 82,10 ± 14,36º en las piernas izquierda y derecha, respectivamente. La media del EPR de ambas piernas fue de 81,90 ± 12,70º. La distancia media en el SR fue de -1,54 ± 8,09 cm. En el L-Hfx, el valor medio fue de 91,08º ± 9,32º. La correlación entre el <span class="hlt">test</span> EPR medio de ambas piernas respecto a la distancia alcanzada en el <span class="hlt">test</span> DDP y el ángulo L-Hfx fueron moderados (L-Hfx: r = -0,72, p < 0,01; SR: r = 0,70, p < 0,01). Ambas variables, de forma independiente, explicaron alrededor del 50% de la varianza (L-Hfx: R2 = 0,52; p < 0,001; SR: R2 = 0,49; p < 0,001).

Results of climb <span class="hlt">tests</span> indicate that when power is changed from approximately 1475 horsepower at 2550 rpm (roughly normal power) to 2400 horsepower at 2700 rpm (approximately military power) there is a loss in propeller efficiency of 3 percent at an altitude of 7000 feet, and 4 percent at 21,000 feet. At an airplane Mach number of 0.7 there is a gain of 9 percent in propeller efficiency when the power coefficient per blade is increased from 0.06 to 0.09.

The primary negative outcome was not achieving grade-level proficiency on achievement <span class="hlt">tests</span>. Logistic regression accounting for repeated measures was used to evaluate for associations between achieving proficiency and demographic data, maternal education, and clinical factors. A total of 362 of 458 (79%) children who underwent surgery for CHD were matched to the Arkansas Department of Education database, 285 of whom had grade 3 and/or 4 achievement <span class="hlt">tests</span> scores. Fewer students with CHD achieved proficiency in literacy and mathematics (P < .05) compared with grade-matched state students. Higher 5-minute Apgar score, shorter duration of hospitalization, and higher maternal education predicted proficiency in literacy (P < .05). White race, no cardiopulmonary bypass, and shorter hospitalization predicted proficiency in mathematics (P < .05). Sex, gestational <span class="hlt">age</span>, <span class="hlt">age</span> at surgery, CHD diagnosis, and type and number of surgeries did not predict <span class="hlt">test</span> proficiency. Compared with all public school students, more children with CHD received special education services (26.9% vs 11.6%; P < .001). Children with CHD had poorer academic achievement and were more likely to receive special education services than all state students.

This study investigates the association between clinical factors and SIBO according to lactulose hydrogen breath <span class="hlt">test</span> (LHBT) result. Methods. A cross-sectional study in a university-based gastroenterology practice was performed. Data was abstracted from the medical records of subjects undergoing LHBT from 6/1/2009 to 6/1/2013. Logistic regression analysis was performed to determine the association between predictor variables: <span class="hlt">age</span>, sex, body mass index (BMI), and positive LHBT, the outcome of interest. Results. LHBT was performed in 791 subjects. Fifty-four percent had a positive LHBT. There was no statistically significant difference between the LHBT results according to <span class="hlt">age</span> or BMI. In females, the likelihood of a positive LHBT increased with <span class="hlt">age</span> (OR 1.02; 95% CI: 1.01–1.03).

Knee stiffness measurements have been reported for the anesthetized rat, but it is difficult to separate the contributions of muscular and ligamentous restraints to the recorded values. in vitro <span class="hlt">testing</span> of isolated rat knees devoid of musculature allows measurement of joint structural properties alone. In order to measure the effects of therapeutic or surgical interventions designed to alter joint stiffness, the opposite extremity is often used as a control. However, right-left stiffness differences for the normal rat knee have not been reported in the literature. If stiffness changes observed for a treatment group are within the normal right-left variation, validity of the results could be questioned. The objectives of this study were to utilize a new <span class="hlt">testing</span> apparatus to measure right-left stiffness differences during knee <span class="hlt">extension</span> in a population of normal rat knees and to document repeatability of the stiffness measurements on successive <span class="hlt">testing</span> days. Moment versus rotation curves were recorded for 15 right-left pairs of normal rat knees on three consecutive days, with overnight specimen storage in a refrigerator. Each knee was subjected to ten loading-unloading cycles, with the last loading curve used for analysis. Angular rotation (AR), defined here as the change in flexion-<span class="hlt">extension</span> angle from a specified applied joint moment, is commonly used as a measure of overall joint stiffness.

This <span class="hlt">test</span> suffers from many disadvantages - it is expensive and time consuming, uses a large number of mice, causes significant animal distress, and suffers from high variability. Recently, the European Pharmacopoeia has recognised the use of a serological potency assay (SPA) as an alternative method to the challenge <span class="hlt">test</span>. This new <span class="hlt">test</span> is based on the determination of rabies neutralising antibody titres in vaccinated mice, by using the modified Rapid Fluorescent Focus Inhibition <span class="hlt">Test</span> (mRFFIT). With the objective of adopting this new method for the batch release of inactivated rabies vaccines, we evaluated its performance on a large collection of rabies vaccines currently assessed in our laboratory. The Fluorescent Antibody Virus Neutralisation <span class="hlt">test</span> (FAVNt) was used in parallel with the mRFFIT, and the results were compared to the mouse challenge <span class="hlt">test</span>. Our results demonstrate that the SPA is capable of estimating the potency of vaccines formulated with a potency margin well above the minimum of 1IU/dose. For low potency vaccines, this new method demonstrated some limitations, due to the recurrent invalidation of the assay. We have also demonstrated the superior sensitivity of the FAVNt when compared to the mRFFIT, and the importance of minimising the risk of detecting non-responders in vaccinated mice. 2015 FRAME.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('https://www.ncbi.nlm.nih.gov/pubmed/20087634','PUBMED'); return false;" href="https://www.ncbi.nlm.nih.gov/pubmed/20087634"><span>Practices and policies of providers <span class="hlt">testing</span> school-<span class="hlt">aged</span> children for tuberculosis, Connecticut, 2008.</span></a></p> <p><a target="_blank" href="https://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pubmed">PubMed</a></p> <p>Lazar, Christina M; Sosa, Lynn; Lobato, Mark N</p> <p>2010-10-01</p> <p>This study identified current practices and policies related to <span class="hlt">testing</span> school children for latent tuberculosis infection (LTBI) in Connecticut.

Multi-level mediation modelling revealed that both negative mood states and dieting significantly mediated the state body dissatisfaction-disordered eating relationships, although the strength of these associations depended on the aspect of disordered eating measured and individual differences in trait body dissatisfaction, internalization of appearance standards, tendency towards dieting, and BMI. Collectively, these results not only support adapting the dual pathway model to the state-level, but also suggest that several of the model implied pathways may be more relevant for individuals with more pathological eating- and body-related concerns and behaviours.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('https://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pmcentrez&artid=4749842','PMC'); return false;" href="https://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pmcentrez&artid=4749842"><span>Who, when, and where? <span class="hlt">Age</span>-related differences on a new memory <span class="hlt">test</span></span></a></p> <p><a target="_blank" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pmc">PubMed Central</a></p> <p>Sumida, Catherine A.; Holden, Heather M.; Van Etten, Emily J.; Wagner, Gabrielle M.; Hileman, Jacob D.</p> <p>2016-01-01</p> <p>Our study examined <span class="hlt">age</span>-related differences on a new memory <span class="hlt">test</span> assessing memory for “who,” “when,” and “where,” and associations among these elements.

These results have methodological implications because of the implied risk of measuring (lack of) computer proficiency in addition to bona fide cognitive deficits.

Participants included 164 students (86 girls, 78 boys; mean <span class="hlt">age</span>, 11.5 ± 2.5 years) recruited from a grade school in a metropolitan area located in the southwestern United States. Students performed an equipment-free, moderate-to-high intensity, dynamic core conditioning warm-up routine once a week for a period of 6 weeks during the start of their physical education classes. The intervention consisted of 10 different dynamic core conditioning exercises performed at a 30-second duration per exercise totaling 5 minutes per session.

We are interested whether these persist after cessation and extend to specific cognitive domains. Design Randomized controlled clinical trial Setting Fourteen clinical centers of the Women's Health Initiative Participants 2,304 women <span class="hlt">aged</span> 65-80 years and free of probable dementia at enrollment Intervention 0.625 mg/day of CEE, with or without medroxyprogesterone acetate (MPA, 10 mg/day), and matching placebos Measurements Annual administrations of a battery of cognitive <span class="hlt">tests</span> during and following the trial Methods General linear models were used to compare on-trial and post-trial mean standardized <span class="hlt">test</span> scores between treatment groups, with adjustment for baseline risk factors for cognitive impairment. Results Assignment to CEE-based therapies was associated with small mean relative decrements in global and several domain-specific cognitive functions on-trial, which largely persisted through up to 4 years post-trial. The strongest statistical evidence was for global cognitive function: 0.07 standard deviation decrements both on-trial (p=0.007) and post-trial (p=0.01). Among domain specific scores, the mean relative decrements were slightly smaller, were less significant, and tended to be larger for CEE-alone therapy. Conclusions CEE-based therapies, when initiated after <span class="hlt">age</span> 65 years, produce a small broad-based decrement in cognitive function that persists after their use is stopped. The differences in cognitive function however are small and would not be detectable or have clinical significance for an individual woman. Differences in effects among cognitive domains suggest that more than one mechanism may be involved.

Using cool main-sequence (MS) stars in Praesepe, we define empirical corrections to the Lejeune et al. color-effective temperature (Teff) relations down to Teff ~ 3600 K, complementing our previous work based on the Hyades and the Pleiades. We apply empirically corrected isochrones to existing optical and near-infrared photometry of cool (Teff ~ 5500 K) and metal-rich ([Fe/H]=+0.37) MS stars in NGC 6791, and find that color-excess and distance estimates from color-magnitude diagrams with different color indices converge on each other at the precisely known metallicity of the cluster. Along with a satisfactory agreement with eclipsing binary data in the cluster, we view the improved internal consistency as a validation of our calibrated isochrones at super-solar metallicities. For very cool stars (Teff < 4800 K), however, we find that BV colors of our models are systematically redder than the cluster photometry by ~0.02 mag. We use color-Teff transformations from the infrared flux method (IRFM) and alternative photometry to examine a potential color-scale error in the input cluster photometry. After excluding BV photometry of these cool MS stars, we derive E(B-V)=0.105±0.014, [M/H]=+0.42±0.07, (m-M)0 = 13.04±0.09, and the <span class="hlt">age</span> of 9.5±0.3 Gyr for NGC 6791.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://hdl.handle.net/2060/19890018840','NASA-TRS'); return false;" href="http://hdl.handle.net/2060/19890018840"><span><span class="hlt">Age</span>-related changes in human vestibulo-ocular reflexes: Sinusoidal rotation and caloric <span class="hlt">tests</span></span></a></p> <p><a target="_blank" href="http://ntrs.nasa.gov/search.jsp">NASA Technical Reports Server (NTRS)</a></p> <p>Peterka, R.

METHOD: The study group was composed of 56 healthy elderly subjects who underwent neuropsychological assessment and quantitative magnetic resonance imaging.

However, it is expected that both cane and softwood fiberboard assemblies will perform satisfactorily in conforming packages stored in a typical KAC storage environment for up to 15 years. <span class="hlt">Aging</span> and <span class="hlt">testing</span> of softwood fiberboard will continue and additional data will be collected. Additional samples will be added to each <span class="hlt">aging</span> environment, to support development of an <span class="hlt">aging</span> model specific to softwood fiberboard. Post-conditioning data have been measured on samples from a single softwood fiberboard assembly, and baseline data are also available from a limited number of vendor-provided samples. This provides minimal information on the possible sample-to-sample variation exhibited by softwood fiberboard. Data to date are generally consistent with the range seen in cane fiberboard, but some portions of the data trends are skewed toward the lower end of that range. Two additional softwood fiberboard source packages have been obtained and will begin to provide data on the range of variability of this material.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('https://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pmcentrez&artid=4116362','PMC'); return false;" href="https://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pmcentrez&artid=4116362"><span>Development and psychometric <span class="hlt">testing</span> of the active <span class="hlt">aging</span> scale for Thai adults</span></a></p> <p><a target="_blank" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pmc">PubMed Central</a></p> <p>Thanakwang, Kattika; Isaramalai, Sang-arun; Hatthakit, Urai</p> <p>2014-01-01</p> <p>Background Active <span class="hlt">aging</span> is central to enhancing the quality of life for older adults, but its conceptualization is not often made explicit for Asian elderly people. Little is known about active <span class="hlt">aging</span> in older Thai adults, and there has been no development of scales to measure the expression of active <span class="hlt">aging</span> attributes. Purpose The aim of this study was to develop a culturally relevant composite scale of active <span class="hlt">aging</span> for Thai adults (AAS-Thai) and to evaluate its reliability and validity. Methods Eight steps of scale development were followed: 1) using focus groups and in-depth interviews, 2) gathering input from existing studies, 3) developing preliminary quantitative measures, 4) reviewing for content validity by an expert panel, 5) conducting cognitive interviews, 6) pilot <span class="hlt">testing</span>, 7) performing a nationwide survey, and 8) <span class="hlt">testing</span> psychometric properties. In a nationwide survey, 500 subjects were randomly recruited using a stratified sampling technique. Statistical analyses included exploratory factor analysis, item analysis, and measures of internal consistency, concurrent validity, and test–retest reliability. Results Principal component factor analysis with varimax rotation resulted in a final 36-item scale consisting of seven factors of active <span class="hlt">aging</span>: 1) being self-reliant, 2) being actively engaged with society, 3) developing spiritual wisdom, 4) building up financial security, 5) maintaining a healthy lifestyle, 6) engaging in active learning, and 7) strengthening family ties to ensure care in later life. These factors explained 69% of the total variance. Cronbach’s alpha coefficient for the overall AAS-Thai was 0.95 and varied between 0.81 and 0.91 for the seven subscales. Concurrent validity and test–retest reliability were confirmed.

The present study <span class="hlt">tested</span> the tenets of objectification theory with a sample of 316 bisexual women and further extended this theory by examining the roles of 2 minority stressors-antibisexual discrimination and internalized biphobia-that are contextually salient for bisexual women. A latent variable structural equation model was conducted, and the model yielded a good fit to the data. Antibisexual discrimination and internalized biphobia (but not sexual objectification experiences) yielded significant unique links with internalization of sociocultural standards of attractiveness (internalization of CSA). Next, internalization of CSA yielded a significant unique link with body surveillance. In addition, antibisexual discrimination, internalization of CSA, and body surveillance yielded significant unique links with body shame. Finally, sexual objectification experiences, internalization of CSA, and body shame yielded significant unique links with eating disorder symptomatology. Beyond the direct relations, antibisexual discrimination yielded significant positive indirect links with body surveillance, body shame, and eating disorder symptoms. Internalization of CSA yielded significant positive indirect links with body shame and eating disorder symptoms. Lastly, body surveillance yielded a significant positive indirect link with eating disorder symptoms. Implications for research and practice with bisexual women are discussed.

Stress <span class="hlt">tests</span> have been performed in boreholes in-situ and under high head pressures. For a pre-fractured rock system, data analysis must incorporate the effects of opening and closing of fractures. As the head pressure increases form ambient, the aperture of the existing dilated fractures increase. The fracture surface area remains constant until the excess head increases to above a critical pressure, when induced fractures can open and existing fractures may propagate. These will furnish a larger rock surface area thereby allowing a more rapid percolation of the water into the rock matrix. We have extended previous models by specifying a functional dependence of both existing fracture aperture and induced fracture surface area and volume on the excess water pressure. Relationships are obtained through the mass conservation laws and these predictions are used as discriminative graphs, with the most useful being pressure versus rate of pressure change. Such type-curves are applied to; Yucca Mountain data with interpretation in terms of the applicable fracture systems and the critical pressure. Estimates of the critical pressure are obtained and usually lie in the range of 10 to 30 bars which is appreciably lower than that expected from the lithostatic pressure effects. This implies that large dilational stresses exist at Yucca Mountain.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('https://www.ncbi.nlm.nih.gov/pubmed/1140562','PUBMED'); return false;" href="https://www.ncbi.nlm.nih.gov/pubmed/1140562"><span><span class="hlt">Testing</span> the protein error theory of <span class="hlt">ageing</span>: a reply to Baird, Samis, Massie and Zimmerman.</span></a></p> <p><a target="_blank" href="https://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pubmed">PubMed</a></p> <p>Holliday, R</p> <p>1975-01-01</p> <p>A major prediction of Orgel's theory is that the misincorporation of amino acids into proteins will increase with <span class="hlt">age</span>.

In the application of polyolefin geosynthetics, a major issue is an estimate of the materials durability (i.e. service lifetime) under various <span class="hlt">aging</span> conditions. Antioxidant packages are added to the polyolefin products to extend the induction time, during which antioxidants are gradually depleted and polymer oxidation reactions are prevented. In this PhD study, an improved laboratory accelerating <span class="hlt">aging</span> method under elevated and high pressure environments was applied to evaluate the combined effect of temperature and pressure on the depletion of the antioxidants and the oxidation of polymers. Four types of commercial polyolefn geosynthetic materials selected for <span class="hlt">aging</span> <span class="hlt">tests</span> included HDPE geogrid, polypropylene woven and nonwoven geotextiles. A total of 33 different temperature/pressure <span class="hlt">aging</span> conditions were used, with the incubation duration up to 24 months. The applied oven temperature ranged from 35°C to 105°C and the partial oxygen pressure ranged from 0.005 MPa to 6.3 MPa. Using the Oxidative Induction Time (OIT) <span class="hlt">test</span>, the antioxidant depletion, which is correlated to the decrease of the OIT value, was found to follow apparent first-order decay. The OIT data also showed that, the antioxidant depletion rate increased with temperature according to the Arrhenius equation, while under constant temperatures, the rate increased exponentially with the partial pressure of oxygen. A modified Arrhenius model was developed to fit the antioxidant depletion rate as a function of temperature and pressure and to predict the antioxidant lifetime under various field conditions. This study has developed new temperature/pressure incubation <span class="hlt">aging</span> <span class="hlt">test</span> method with lifetime prediction models.

Method The sample was composed of 120 community-dwelling older adults, with a mean of <span class="hlt">age</span> of 71.0 years (SD = 6.3). Mediational analyses and structural equation modeling were used to analyze and compare different models. Results Greater knowledge about <span class="hlt">aging</span> was negatively related to both intolerance of uncertainty and worry, and its effect on worry was partially mediated by intolerance of uncertainty. The mediational model obtained an excellent fit to the data (i.e. Goodness of fit index (GFI) = 0.995) and clearly had a better fit than alternative models. Conclusion These results suggest that a good knowledge of the <span class="hlt">aging</span> process could help decrease aversive uncertainty and thus reduce the level of worry among older adults.

The time-dependent data of specific surface areas were subsequently used to construct kinetics of sintering at the specific temperature. According to the analytical results of the catalysts' properties, the increase in <span class="hlt">aging</span> temperature causes an increase in pore size of the catalysts and a decrease in the specific surface area. The <span class="hlt">aged</span> catalysts all exhibited lower performances than the fresh ones. The reduction in catalytic activity is consistent with the reduction in the loss of specific surface area. The finding of catalytic properties' dependence on temperature is consistent with the thermally activated theory. In contrast, the effect of the <span class="hlt">aging</span> time on the specific surface area was only significant during the initial few hours. The high correlation between specific surface areas measured by the Brunauer-Emmett-Teller (BET) method and predicted by the constructed model verifies that the prediction models can predict the sintering rate reasonably under the <span class="hlt">aging</span> conditions discussed in this study. As compared to automobile catalytic converters, the differences of structures and <span class="hlt">aging</span> conditions are made less obvious by the deactivation phenomena of motorcycles.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://hdl.handle.net/2060/20090016321','NASA-TRS'); return false;" href="http://hdl.handle.net/2060/20090016321"><span>Wind-Tunnel <span class="hlt">Tests</span> of Several Model Tractor-Propeller and Pusher-Propeller Wing <span class="hlt">Extension</span>-Shaft Arrangements, Special Report</span></a></p> <p><a target="_blank" href="http://ntrs.nasa.gov/search.jsp">NASA Technical Reports Server (NTRS)</a></p> <p>Harmon, Hubert N.</p> <p>1941-01-01</p> <p><span class="hlt">Tests</span> were made in the 20-foot propeller-research tunnel to investigate the possibility of obtaining increased net efficiencies of propeller-nacelle units by enclosing the engines in the wings and by using <span class="hlt">extension</span> shafts.

The efficiencies for the pusher position appeared to be more critically affected by spinner size than those for the tractor position.

Part of this research addresses the friction that occurs at the interface between the valve disc and the valve body seats during operation of a gate valve. In most gate valves, these surfaces are hardfaced with Stellite 6, a cobalt-based alloy. The nuclear industry has developed methods to analytically predict the thrust needed to operate these valves at specific pressure conditions. To produce accurate valve thrust predictions; the analyst must have a reasonably accurate, though conservative, estimate of the coefficient of friction at the disc-to-seat interface. One of the questions that remains to be answered is whether, and to what extent, <span class="hlt">aging</span> of the disc and seat surfaces affects the disc-to-seat coefficient of friction. Specifically, does the accumulation of a surface film due to <span class="hlt">aging</span> of these surfaces increase the coefficient of friction and if so, how much? This paper presents results of specimen <span class="hlt">tests</span> addressing this issue with emphasis on the following: • The change in the friction coefficient of Stellite 6 as it <span class="hlt">ages</span> and whether the friction reaches a plateau. • The effect periodic gate valve cycling due to in-service <span class="hlt">testing</span> has on the friction coefficient. • The results of an independent review of the <span class="hlt">test</span> methods, processes, and the results of the research to date. • The status of ongoing <span class="hlt">aging</span> and friction <span class="hlt">testing</span>.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('https://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pmcentrez&artid=4356796','PMC'); return false;" href="https://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pmcentrez&artid=4356796"><span>In Vitro Susceptibility <span class="hlt">Testing</span> of Eravacycline Is Unaffected by Medium <span class="hlt">Age</span> and Nonstandard Assay Parameters</span></a></p> <p><a target="_blank" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pmc">PubMed Central</a></p> <p>Pillar, Chris M.; Sahm, Daniel F.; Sutcliffe, Joyce A.</p> <p>2015-01-01</p> <p>Eravacycline is a fluorocycline antibiotic in phase 3 clinical development for complicated intra-abdominal and urinary tract infections.

First, performance was recorded for 66 mice in rotorod, tightrope, grip strength, exploratory activity, and runwheel activity tasks at 24 mo of <span class="hlt">age</span>. Except in the rotorod task, performance was positively and significantly correlated to lifespan, i.e. better performance indicated longer lifespan. Body weight and body temperature were also significantly correlated with lifespan, while water consumption was negatively related. Using the five behavioral scores in a multiple regression analysis, about 40% of the variance in lifespan was explainable. When measures of body weight, body temperature, and water consumption were added to the regression equation, about 54% of the variance in lifespan could be explained.

Methods: ankle proprioception was assessed in 289 participants (131 women) of the Baltimore Longitudinal Study of <span class="hlt">Aging</span> (BLSA); the participants <span class="hlt">aged</span> 51–95 years and were blinded during <span class="hlt">testing</span>. Results: the average minimum perceived ankle rotation was 1.11° (SE = 0.07) in women and 1.00° (SE = 0.06) in men, and it increased with <span class="hlt">ageing</span> in both sexes (P < 0.001, for both). Ankle tracking performance, which is the ability to closely follow with the left ankle, a rotational movement induced on the right ankle by a torque motor, declines with <span class="hlt">ageing</span> in both men and women (P = 0.018 and P = 0.011, respectively). Conclusions: a simple, standardised method for assessing ankle proprioception was introduced in this study using a customized <span class="hlt">test</span> instrument, software and <span class="hlt">test</span> protocol. <span class="hlt">Age</span>-associated reduction in ankle proprioception was confirmed from two subtests of threshold and tracking separately for women and men.

The charges were newly pressed from 37.5 year-old molding powder. We compare these results to equivalent data performed on the same lot when it was 3.5 years old. Comparison of the detonation energy inferred from detonation speed to that inferred from wall motion suggests that the HMX energy is unchanged but the NC energy has decreased to {approx}25% of its original value. The degradation of explosives and their binders is a subject of continual interest. Secondary explosives such as HMX are sufficiently stable near room temperature that they do not measurably degrade over a period of at least several decades. For formulated systems the bigger concern is binder degradation, for which the three main issues are strength, initiation safety, and (if the binder is energetic) energy content. In this paper we examine the detonation energy of new and <span class="hlt">aged</span> PBX 9404 (94 wt% HMX, 3 wt% tris-{beta} chloroethylphosphate (CEF), 2.9 wt% nitrocellulose (NC), 0.1 wt% diphenylamine (DPA) [1, 2]), measured via the detonation copper cylinder <span class="hlt">test</span>. In 1959, two independent PBX 9404 accidents [3] raised serious concerns about the safety of the formulation. Over about a decade's time, Los Alamos pursued a safer, energetically equivalent replacement, which ultimately became PBX 9501. In order to accurately compare the performance of the PBX 9404 and PBX 9501 formulations, W. Campbell and R. Engelke (C & E) developed a stringent cylinder <span class="hlt">test</span> protocol that they called the Los Alamos Precision Cylinder <span class="hlt">Test</span> [4].

Cardiovascular comorbidities are a known risk factor for impaired mobility in elderly individuals. Motor impairments in Parkinson disease are conventionally ascribed to nigrostriatal dopaminergic denervation although progressive gait and balance impairments become more common with <span class="hlt">aging</span> and often show limited response to dopaminergic replacement therapies.

Although senescent declines in survival are well documented in humans and in domestic and laboratory animals, evidence for their occurrence and importance in wild animal species remains limited and equivocal. Several recent papers have suggested that methodological issues may contribute to this problem, and have encouraged investigators to improve sampling designs and to analyse their data using recently developed approaches to modelling of capture-mark-recapture data. Here we report on a three-year, two-site, mark-recapture study of known-<span class="hlt">aged</span> common terns (Sterna hirundo) in the north-eastern USA. The study was nested within a long-term ecological study in which large numbers of chicks had been banded in each year for > 25 years. We used a range of models to <span class="hlt">test</span> the hypothesis of an influence of <span class="hlt">age</span> on survival probability. We also <span class="hlt">tested</span> for a possible influence of sex on survival. The cross-sectional design of the study (one year's parameter estimates) avoided the possible confounding of effects of <span class="hlt">age</span> and time. The study was conducted at a time when one of the study sites was being colonized and numbers were increasing rapidly. We detected two-way movements between the sites and estimated movement probabilities in the year for which they could be modelled. We also obtained limited data on emigration from our study area to more distant sites. We found no evidence that survival depended on either sex or <span class="hlt">age</span>, except that survival was lower among the youngest birds (<span class="hlt">ages</span> 2-3 years). Despite the large number of birds included in the study (1599 known-<span class="hlt">aged</span> birds, 2367 total), confidence limits on estimates of survival probability were wide, especially for the oldest <span class="hlt">age</span>-classes, so that a slight decline in survival late in life could not have been detected.

To make sure that the quality of the simulant is acceptable, the production method was scaled up starting from laboratory-prepared simulant through 15-gallon vendor prepared simulant and 250-gallon vendor prepared simulant before embarking on the production of the 3500-gallon simulant batch by the vendor. The 3500-gallon PEP simulant batches were packaged in 250-gallon high molecular weight polyethylene totes at NOAH Technologies. The simulant was stored in an environmentally controlled environment at NOAH Technologies within their warehouse before blending or shipping. For the 15-gallon, 250-gallon, and 3500-gallon batch 0, the simulant was shipped in ambient temperature trucks with shipment requiring nominally 3 days. The 3500-gallon batch 1 traveled in a 70-75°F temperature controlled truck. Typically the simulant was uploaded in a PEP receiving tank within 24-hours of receipt. The first uploading required longer with it stored outside. Physical and chemical characterization of the 250-gallon batch was necessary to determine the effect of <span class="hlt">aging</span> on the simulant in transit from the vendor and in storage before its use in the PEP. Therefore, <span class="hlt">aging</span> <span class="hlt">tests</span> were conducted on the 250-gallon batch of the vendor-produced PEP blended feed simulant to identify and determine any changes to the physical characteristics of the simulant when in storage. The supernate was also chemically characterized. Four <span class="hlt">aging</span> scenarios for the vendor-produced blended simulant were studied: 1) stored outside in a 250-gallon tote, 2) stored inside in a gallon plastic bottle, 3) stored inside in a well mixed 5-L tank, and 4) subject to extended temperature cycling under summer temperature conditions in a gallon plastic bottle.

The scientific medicine did not begin with him, and the succeeding generations of him were not one and the same in opinions. For example, there were the confrontations between the school of Kos and that of Knidos in the very <span class="hlt">age</span> of Hippocrates, as well as the opposition of rationalism and empiricism. The school of Kos was alleged to succeed the tradition of Hippocrates, taking into consideration individual physical conditions and being based on the principle of various clinical methods of physical therapy assuming chronical <span class="hlt">extension</span>. On the contrary, the school of Knidos tended to define the diseases in simple aspects, paying no much attention to the difference of physical conditions and developmental stages of illness. Futhermore, the latter grasped the diseases rather in the point of individual organs than the disorder of physical state of the body. It can be said that the anatomical knowledge was more useful for the school of Knidos. The difference between the two schools can also be found in what purpose the medicine sought after. While Hippocrates attached much importance to physical therapy and made the people including the poor as object of medical treatment, there were doctors in no small number, we can suppose, in pursuit of money, power, worldly glory. As time passed, however, the two schools gradually got similar to each other, the difference of them reduced as well as the tradition of Hippocrates faded. The opposition between rationalism and empiricism in the Hellenistic <span class="hlt">Age</span> shared, in some aspect, the difference of Kos and Knidos. According to Celsus, the conflict between rationalism and empiricism did not refer to pharmacy or anatomy, but just to diet.

Experiment 3 examined performance in subjects instructed to feign symptoms of traumatic brain injury: 44% of subjects produced abnormal completion times on the C-TMT-A, and 18% on the C-TMT-B. Malingering subjects could be distinguished from abnormally slow controls based on (1) disproportionate increases in dwell-time on the C-TMT-A, and (2) greater deficits on the C-TMT-A than on the C-TMT-B. Experiment 4 examined the performance of 28 patients with traumatic brain injury: C-TMT-B completion times were slowed, and TBI patients showed reduced movement velocities on both <span class="hlt">tests</span>. The C-TMT improves the reliability and sensitivity of the trail making <span class="hlt">test</span> of processing speed and executive function.

E.; Zhang, Y.; Fogg, G. E.</p> <p>2004-12-01</p> <p>Recent research shows that dispersion due to geologic heterogeneity can cause large (10's to 100's of yrs) variations in actual groundwater <span class="hlt">age</span> within individual samples drawn from a well, even if well bore mixing is not significant. We hypothesize that the presence of such large ranges in groundwater <span class="hlt">age</span> may cause the mean apparent <span class="hlt">age</span> as estimated from environmental tracers such as CFC's, SF&_{6}, and ^{3}H-^{3}He to drift measurably during long-term, continuous pumping. This hypothesis was confirmed by 3-D numerical experiments wherein variation in groundwater <span class="hlt">ages</span> under high-rate (\\sim0.06 m^{3}/s; 1,000 gpm) long-term pumping was modeled using backward-time random walk particle tracking techniques combined with geostatistical simulations of hydrofacies heterogeneity. Results indicate that the <span class="hlt">age</span> distribution within a water sample and the mean apparent <span class="hlt">age</span> implied by environmental tracers is strongly influenced by historical atmospheric concentrations of environmental tracers and subsurface heterogeneity. As a partial implementation of this same experiment in the field, an abandoned well was pumped at a low rate (\\sim0.005 m^{3}/s; 75 gpm) during 53 days. Water samples were collected from the top and bottom of a 25 foot well screen at 12 hour intervals for the first 30 days and were analyzed for CFC's, SF&6, and 3H-3He. The measured tracer <span class="hlt">ages</span> indicate that 1) CFC-11 apparent <span class="hlt">ages</span> increased with time within the first five days of pumping and then remained constant for the remainder of the pump <span class="hlt">test</span>; 2) trends in CFC-12, CFC-113 and SF&_{6}$ indicate a discrepancy in apparent <span class="hlt">ages</span> with CFC-11, 3) water reaching the top interval is younger than water reaching the bottom interval. Gas samples were collected from the unsaturated zone to investigate possible CFC contamination and tracer concentration spatial variations in the pumping well recharge zone. Potential effects of heterogeneity and local CFC contamination on the monitoring results will be discussed.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://hdl.handle.net/2060/19980209930','NASA-TRS'); return false;" href="http://hdl.handle.net/2060/19980209930"><span>Correlation of Chemical and Physical <span class="hlt">Test</span> Data For the Environment <span class="hlt">Ageing</span> of Coflon (PVDF).

P.</p> <p>1997-01-01</p> <p>This report aims to identify correlations between mechanical property changes and chemical/morphological structure changes for Coflon. It is intended both to illustrate the overall methodology and to indicate the <span class="hlt">testing</span> that needs to be undertaken in order to obtain correlations. Many fluid exposures have now been carried out on Coflon during the project and many data generated as a result. The report summarises the changes observed in mechanical and physical properties and relates these as well as possible to the chemistry thought to be occurring during <span class="hlt">ageing</span>. For this purpose, data have been collated from already-issued MERL and TRI technical and progress reports. Most of the mechanical <span class="hlt">testing</span> of <span class="hlt">aged</span> testpieces has been performed soon after the completion of the exposure; however, there is of necessity a delay in obtaining chemical analysis of the same testpieces, so that more physical than chemical data are shown. Three fluids have so far caused measurable deterioration of Coflon, these being: methanol (Fluid A), a methanol and amine mixture (Fluid G), and a mixture of methane, carbon dioxide gas and hydrogen sulphide gas plus aqueous amine (Fluid F). Only the effects of these fluids will be dealt with in any detail in this report, although other fluids are assessed to give relevant background information. Relevant <span class="hlt">test</span> data collated here include: tensile modulus and related properties, mode of sample failure at break, fracture toughness, fatigue crack growth rate and resistance, stress relaxation rate, permeation coefficients, % crystallinity and molecular weight distributions together with changes in fluorine levels, and other observations where appropriate. However, not all of these were obtained for every <span class="hlt">ageing</span> condition. Because of the wide range of <span class="hlt">tests</span> employed, and the different ways in which their results are obtained, the following section has been included to serve as a background for making comparisons.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('https://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pmcentrez&artid=4495451','PMC'); return false;" href="https://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pmcentrez&artid=4495451"><span>4-Second Exercise <span class="hlt">Test</span>: Reference Values for <span class="hlt">Ages</span> 18–81 Years</span></a></p> <p><a target="_blank" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pmc">PubMed Central</a></p> <p>Araújo, Claudio Gil; de Castro, Claudia Lucia Barros; Franca, João Felipe; Ramos, Plínio Santos</p> <p>2015-01-01</p> <p>Background Physiological reflexes modulated primarily by the vagus nerve allow the heart to decelerate and accelerate rapidly after a deep inspiration followed by rapid movement of the limbs. This is the physiological and pharmacologically validated basis for the 4-s exercise <span class="hlt">test</span> (4sET) used to assess the vagal modulation of cardiac chronotropism. Objective To present reference data for 4sET in healthy adults. Methods After applying strict clinical inclusion/exclusion criteria, 1,605 healthy adults (61% men) <span class="hlt">aged</span> between 18 and 81 years subjected to 4sET were evaluated between 1994 and 2014. Using 4sET, the cardiac vagal index (CVI) was obtained by calculating the ratio between the duration of two RR intervals in the electrocardiogram: 1) after a 4-s rapid and deep breath and immediately before pedaling and 2) at the end of a rapid and resistance-free 4-s pedaling exercise. Results CVI varied inversely with <span class="hlt">age</span> (r = -0.33, p < 0.01), and the intercepts and slopes of the linear regressions between CVI and <span class="hlt">age</span> were similar for men and women (p > 0.05). Considering the heteroscedasticity and the asymmetry of the distribution of the CVI values according to <span class="hlt">age</span>, we chose to express the reference values in percentiles for eight <span class="hlt">age</span> groups (years): 18–30, 31–40, 41–45, 46–50, 51–55, 56–60, 61–65, and 66+, obtaining progressively lower median CVI values ranging from 1.63 to 1.24. Conclusion The availability of CVI percentiles for different <span class="hlt">age</span> groups should promote the clinical use of 4sET, which is a simple and safe procedure for the evaluation of vagal modulation of cardiac chronotropism.

Poor visibility, which is exacerbated by <span class="hlt">age</span>-related changes in vision, is a leading contributor to fatal nighttime crashes. There is little evidence, however, concerning the extent to which drivers recognize and compensate for their visual limitations at night. Young, middle-<span class="hlt">aged</span>, and elder participants drove on a closed road course in day and night conditions at a "comfortable" speed without speedometer information. During night <span class="hlt">tests</span>, headlight intensity was varied over a range of 1.5 log units using neutral density filters. Average speed and recognition of road signs decreased significantly as functions of increased <span class="hlt">age</span> and reduced illumination. Recognition of pedestrians at night was significantly enhanced by retroreflective markings of limb joints as compared with markings of the torso, and this benefit was greater for middle-<span class="hlt">aged</span> and elder drivers. Lane keeping showed nonlinear effects of lighting, which interacted with task conditions and drivers' lateral bias, indicating that older drivers drove more cautiously in low light. Consistent with the hypothesis that drivers misjudge their visual abilities at night, participants of all <span class="hlt">age</span> groups failed to compensate fully for diminished visual recognition abilities in low light, although older drivers behaved more cautiously than the younger groups. These findings highlight the importance of educating all road users about the limitations of night vision and provide new evidence that retroreflective markings of the limbs can be of great benefit to pedestrians' safety at night.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('https://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pmcentrez&artid=3630906','PMC'); return false;" href="https://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pmcentrez&artid=3630906"><span>Biomechanics of the Human Posterior Sclera: <span class="hlt">Age</span>- and Glaucoma-Related Changes Measured Using Inflation <span class="hlt">Testing</span></span></a></p> <p><a target="_blank" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pmc">PubMed Central</a></p> <p>Coudrillier, Baptiste; Tian, Jing; Alexander, Stephen; Myers, Kristin M.; Quigley, Harry A.; Nguyen, Thao D.</p> <p>2012-01-01</p> <p>Purpose. The objective of this study was to measure the biomechanical response of the human posterior sclera in vitro and to estimate the effects of <span class="hlt">age</span> and glaucoma. Methods. Scleral specimens from 22 donors with no history of glaucoma and 11 donors with a history of glaucoma were excised 3 mm posterior to the equator and affixed to an inflation chamber. Optic nerve cross-sections were graded to determine the presence of axon loss. The time-dependent inflation response was measured in a series of pressure-controlled load–unload <span class="hlt">tests</span> to 30 mm Hg and creep <span class="hlt">tests</span> to 15 and 30 mm Hg. Circumferential and meridional strains were computed from the digital image correlation displacements, and midposterior stresses were determined from pressure and deformed geometry. Results. Among normal specimens, older <span class="hlt">age</span> was predictive of a stiffer response and a thinner sclera. In the <span class="hlt">age</span> group 75 to 93, diagnosed glaucoma eyes with axon damage were thicker than normal eyes. Both damaged and undamaged glaucoma eyes had a different strain response in the peripapillary sclera characterized by a stiffer meridional response. Undamaged glaucoma eyes had slower circumferential creep rates in the peripapillary sclera than normal eyes. Glaucoma eyes were not different from normal eyes in stresses and strains in the midposterior sclera. Conclusions. The observed differences in the biomechanical response of normal and glaucoma sclera may represent baseline properties that contribute to axon damage, or may be characteristics that result from glaucomatous disease.

The most common input devices, touchpad (experiment 1) and trackpoint (experiment 2) were examined. So far, the evaluation of mobile input devices has been restricted to younger users.

The results show that <span class="hlt">ageing</span> is a central factor to be considered in input device design. Middle-<span class="hlt">aged</span> users were significantly slower than younger users when executing the different tasks.

A high percentage (40.1%) of the normative sample obtained at least one or more low scores (i.e., false positives). In contrast, the risk of having low scores was much less important (<2%) when considering the combinations of 2 <span class="hlt">test</span>-scores. Low scores are very common in healthy older subjects and are thus not necessarily pathological or indicative of truly impaired functioning. The information derived from a cognitive profile may provide a greater clinical relevance in an individual, since very few of the healthy older adults obtained low scores on combinations of 2 <span class="hlt">test</span>-scores. © 2017 S.

The fecal immunochemical <span class="hlt">test</span> (FIT) may be useful for advanced colorectal neoplasia (ACRN) screening in a young population. To evaluate the diagnostic accuracy of FIT in a young population. The diagnostic performance of FIT for detecting ACRN was compared among the following <span class="hlt">age</span> groups who underwent FIT and colonoscopy as part of a comprehensive health screening program: 30-39, 40-49, and ≥50 years. Of 26,316 participants, 464 (1.8%) had ACRN and 805 (3.1%) showed positive FIT results. No significant differences in the sensitivity (22.1%, 17.2%, and 22.0%; p=0.435) and specificity (97.2%, 97.4%, and 96.9%; p=0.344) of FIT for detecting ACRN were observed among the groups.

Physical, mechanical and thermal properties have been measured following varying periods of conditioning in each of several environments. These <span class="hlt">tests</span> have been conducted in the same manner as previous <span class="hlt">testing</span> on cane fiberboard samples. Overall, similar <span class="hlt">aging</span> trends are observed for softwood and cane fiberboard samples. Some of the observed differences result from the limited exposure periods of the softwood fiberboard samples, and the impact of seasonal humidity levels. <span class="hlt">Testing</span> following additional conditioning will continue and should eliminate this bias. Post-conditioning data have been measured on a single softwood fiberboard assembly, and baseline data are also available from a limited number of vendor-provided samples. This provides minimal information on the possible sample-to-sample variation exhibited by softwood fiberboard. Data to date are generally consistent with the range seen in cane fiberboard, but much of the compression strength data tends toward the lower end of that range. Further understanding of the variability of softwood fiberboard properties will require <span class="hlt">testing</span> of additional material. Cane fiberboard wall sheathing is specified for thermal insulation and impact resistance in 9975 shipping packages. Softwood fiberboard manufactured by Knight-Celotex was approved as an acceptable substitute for transportation in 2008.

Single nucleotide polymorphisms (SNPs) in several genes including ApoE, MTHFR, HFE and FTO are known to increase the risk of both conditions. The E4 allele of the ApoE polymorphism is the most <span class="hlt">extensively</span> studied risk factor for AD and increases the risk of coronary heart disease by approximately 40%. It furthermore displays differential therapeutic responses with use of cholesterol-lowering statins and acetylcholinesterase inhibitors, which may also be due to variation in the CYP2D6 gene in some patients. Disease expression may be triggered by gene-environment interaction causing conversion of minor metabolic abnormalities into major brain disease due to cumulative risk.

In this review, the concept of pathology supported genetic <span class="hlt">testing</span> (PSGT) for CVD is described in this context. PSGT combines DNA <span class="hlt">testing</span> with biochemical measurements to determine gene expression and to monitor response to treatment. The aim is to diagnose treatable disease subtypes of complex disorders, facilitate prevention of cumulative risk and formulate intervention strategies guided from the genetic background.

This study investigates PPSL signal intensities in order to assess its usefulness in obtaining relative OSL <span class="hlt">ages</span> from linear regressions created by interpolating newly generated PPSL values of samples with existing OSL <span class="hlt">ages</span> from two <span class="hlt">extensive</span> Nilotic-sourced dunefields. Eighteen OSL-dated sand samples from two quartz-dominated sand systems in Israel were studied:(1) the Mediterranean littoral-sourced coastal dunefields that formed since the middle Holocene; and (2) the inland north-western Negev desert dunefield that rapidly formed between the Last Glacial Maximum and the Holocene. Samples from three coastal dune profiles were also measured. Results show that the PPSL signals differ by several orders of magnitude between modern and late Pleistocene sediments. The coastal and desert sand have different OSL <span class="hlt">age</span> - PPSL signal ratios. Coastal sand show better correlations between PPSL values and OSL <span class="hlt">ages</span>. However, using regression curves for each dunefield to interpolate <span class="hlt">ages</span> is less useful than expected as samples with different <span class="hlt">ages</span> exhibit similar PPSL signals.

This study demonstrates that a rapid assessment of the relative OSL <span class="hlt">ages</span> across different and <span class="hlt">extensive</span> dunefields is useful and may be achieved. However, the OSL <span class="hlt">ages</span> obtained by linear regression are only a very rough <span class="hlt">age</span> estimate. The reasons for not obtaining more reliable <span class="hlt">ages</span> need to be better understood, as several variables can affect the PPSL signal such as mineral provenance, intrinsic grain properties, micro-dosimetry and moisture content.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('https://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pmcentrez&artid=2858599','PMC'); return false;" href="https://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pmcentrez&artid=2858599"><span>The Oral Trail Making <span class="hlt">Test</span>: Effects of <span class="hlt">Age</span> and Concurrent Validity†</span></a></p> <p><a target="_blank" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pmc">PubMed Central</a></p> <p>Mrazik, Marty; Millis, Scott; Drane, Daniel L.</p> <p>2010-01-01</p> <p>The oral version of the Trail Making <span class="hlt">Test</span> (OTMT) is a neuropsychological measure that provides an assessment of sequential set-shifting without the motor and visual demands of the written TMT (WTMT). Originally purposed to serve as an oral analog of the WTMT, the OTMT provides a means to evaluate patients with physical restrictions. However, formal validity studies and available normative data remain sparse. In a sample of healthy adults (n = 81), a strong correlation was observed between OTMT-B and its written counterpart (r = .62), but the correlations were weak between OTMT-A and either written version of the TMT. OTMT-B was significantly correlated with <span class="hlt">age</span> but not with education or gender, whereas OTMT-A was not significantly correlated with demographic factors. The WTMT to OTMT ratios observed in the current study were generally lower than previously reported and varied across <span class="hlt">age</span> groups, suggesting that the recommended use of a uniform conversion factor to predict one performance based on the other should be cautiously undertaken. Normative data that have been stratified by <span class="hlt">age</span> are provided as well as suggestions for using both versions of the TMT in tandem to better elucidate the nature of cognitive deficits and to aid in the localization of cerebral dysfunction.

PARTICIPANTS 5206 older adults <span class="hlt">aged</span> 65 to 103 from the Dynamic Analyses to Optimise <span class="hlt">Ageing</span> (DYNOPTA) project. MEASUREMENTS Included were: self-reported driving status, ABT for driver’s license renewal status, demographics, medical conditions, Mini Mental State Exam (MMSE), and visual acuity. RESULTS After accounting for significant demographic and health covariates, logistic regression analyses revealed that older adults required to undergo ABT were between 2.22 (95% CI= 1.35–3.57, P <.01) and 1.52 (95% CI=1.18–1.92, P<.01) times more likely to report not driving. Similar proportions of drivers with cognitive or visual impairments were found regardless of ABT status. CONCLUSIONS Required ABT for license renewal was associated with lower rates of driving. The proportion of drivers with probable cognitive or visual impairments was similar in those who had ABT and those who did not. Future investigation of the impact of current ABT policies on crash rates and the potential to use other scientifically designed ABT strategies, is therefore needed.

We explored whether a thickened or nonthickened version was best for infants with suspected CMPA, which commonly causes regurgitation/vomiting. Methods Diagnosis of CMPA was based on a positive challenge <span class="hlt">test</span>. We compared the efficacy of two casein <span class="hlt">extensive</span> hydrolysates (eCH), a nonthickened version (NT-eCH) and a thickened version (T-eCH), using a symptom-based score covering regurgitation, crying, stool consistency, eczema, urticarial and respiratory symptoms. Results A challenge was performed in 52/72 infants with suspected CMPA and was positive in 65.4%. All confirmed CMPA cases tolerated eCH. The symptom-based score decreased significantly in all infants within a month, and the highest reduction was in those with confirmed CMPA. Regurgitation was reduced in all infants (6.4 ± 3.2–2.8 ± 2.9, p < 0.001), but fell more with the T-eCH (−4.2 ± 3.2 regurgitations/day vs. −3.0 ± 4.5, ns), especially in infants with a negative challenge (−3.9 ± 4.0 vs. −1.9 ± 3.4, ns). Conclusion eCH fulfilled the criteria for a hypoallergenic formula, and the NT-eCH and T-eCH formulas both reduced CMPA symptoms. The symptom-based score is useful for evaluating how effective dietary treatments are for CMPA.

Physical, mechanical and thermal properties have been measured following varying periods of conditioning in each of several environments. These <span class="hlt">tests</span> have been conducted in the same manner as previous <span class="hlt">testing</span> on cane fiberboard samples. Overall, similar <span class="hlt">aging</span> trends are observed for softwood and cane fiberboard samples, with a few differences. On the positive side, the softwood fiberboard data to date shows less sample-to-sample variation in physical properties than cane fiberboard, and the thermal conductivity decreases at a slower rate at 250F for softwood fiberboard than for cane fiberboard. On the other hand, the softwood fiberboard physical property samples generally show degradation rates greater than cane fiberboard samples in the 185F 30%RH environment. <span class="hlt">Testing</span> following additional conditioning will continue and the addition of samples in other elevated humidity environment(s) will be pursued to identify the extent of these trends. Post-conditioning data have been measured on samples from a single softwood fiberboard assembly, and baseline data are also available from a limited number of vendor-provided samples. This provides minimal information on the possible sample-to-sample variation exhibited by softwood fiberboard. Data to date are generally consistent with the range seen in cane fiberboard, but some portions of the data trends are skewed toward the lower end of that range. Further understanding of the variability of softwood fiberboard properties will require <span class="hlt">testing</span> of additional material.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://adsabs.harvard.edu/abs/2003NIMPA.508..106A','NASAADS'); return false;" href="http://adsabs.harvard.edu/abs/2003NIMPA.508..106A"><span><span class="hlt">Ageing</span> <span class="hlt">tests</span> on the low-resistivity RPC for the ALICE dimuon arm</span></a></p> <p><a target="_blank" href="http://adsabs.harvard.edu/abstract_service.html">NASA Astrophysics Data System (ADS)</a></p> <p>Arnaldi, R.; Baldit, A.; Barret, V.; Bastid, N.; Blanchard, G.; Chiavassa, E.; Cortese, P.; Crochet, Ph.; Dellacasa, G.; De Marco, N.; Drancourt, C.; Dupieux, P.; Espagnon, B.; Ferretti, A.; Forestier, B.; Gallio, M.; Genoux-Lubain, A.; Insa, C.; Jouve, F.; Lamoine, L.; Lefevre, F.; Manso, F.; Mereu, P.; Musso, A.; Oppedisano, C.; Piccotti, A.; Poggio, F.; Royer, L.; Rosnet, Ph.; Saturnini, P.; Scalas, E.; Scomparin, E.; Sigaudo, F.; Travaglia, G.; Vercellin, E.; Alice Collaboration</p> <p>2003-08-01</p> <p>The trigger for the Dimuon Forward Spectrometer of the forthcoming ALICE experiment at CERN LHC will be provided by low-resistivity, single gap Resistive Plate Chambers working in streamer mode.

In this paper, we investigate the effects of vocational interests, previous academic experience, gender and <span class="hlt">age</span> on SJT performance. The SJT was part of the selection process for the Bachelor's degree programme in Medicine at University of Groningen, the Netherlands. All applicants for the academic year 2015-2016 were included and had to choose between learning communities Global Health (n = 126), Sustainable Care (n = 149), Intramural Care (n = 225), or Molecular Medicine (n = 116). This choice was used as a proxy for vocational interest. In addition, all graduate-entry applicants for academic year 2015-2016 (n = 213) were included to examine the effect of previous academic experience on performance. We used MANCOVA analyses with Bonferroni post hoc multiple comparisons <span class="hlt">tests</span> for applicant performance on a six-scenario SJT. The MANCOVA analyses showed that for all scenarios, the independent variables were significantly related to performance (Pillai's Trace: 0.02-0.47, p < .01). Vocational interest was related to performance on three scenarios (p < .01). Graduate-entry applicants outperformed all other groups on three scenarios (p < .01) and at least one other group on the other three scenarios (p < .01). Female applicants outperformed male applicants on three scenarios (p < .01) and <span class="hlt">age</span> was positively related to performance on two scenarios (p < .05). A good fit between applicants' vocational interests and SJT scenario was related to better performance, as was previous academic experience. Gender and <span class="hlt">age</span> were related to performance on SJT scenarios in different settings. Especially the first effect might be helpful in selecting appropriate candidates for areas of health care in which more professionals are needed.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('https://ntrs.nasa.gov/search.jsp?R=20000102418&hterms=Aging&qs=Ntx%3Dmode%2Bmatchall%26Ntk%3DAll%26N%3D0%26No%3D70%26Ntt%3DAging','NASA-TRS'); return false;" href="https://ntrs.nasa.gov/search.jsp?R=20000102418&hterms=Aging&qs=Ntx%3Dmode%2Bmatchall%26Ntk%3DAll%26N%3D0%26No%3D70%26Ntt%3DAging"><span>Polymer-Oxygen Compatibility <span class="hlt">Testing</span>: Effect of Oxygen <span class="hlt">Aging</span> on Ignition and Combustion Properties</span></a></p> <p><a target="_blank" href="http://ntrs.nasa.gov/search.jsp">NASA Technical Reports Server (NTRS)</a></p> <p>Waller, Jess M.; Haas, Jon P.; Wilson, D.

Three elastomers were <span class="hlt">tested</span>: CR rubber (C873-70), FKM fluorocarbon rubber (Viton A), and MPQ silicone rubber (MIL-ZZ-765, Class 2); and three thermoplastics were <span class="hlt">tested</span>: polyhexamethylene adipamide (Zytel 42), polytetrafluoroethylene (Teflon TFE), and polychlorotrifluoroethylene (Neoflon CTFE M400H). Post-<span class="hlt">aging</span> changes in mass, dimensions, tensile strength, elongation at break, and durometer hardness were determined. Also, the compression set was determined for the three elastomers. Results show that the properties under investigation were more sensitive to oxygen pressure at low to moderate temperatures, and more sensitive to temperature at low to moderate oxygen pressures. Inspection of the results also suggested that both chain scissioning and cross-linking processes were operative, consistent with heterogeneous oxidation. Attempts are underway to verify conclusively the occurrence of heterogeneous oxidation using a simple modulus profiling technique. Finally, the effect of <span class="hlt">aging</span> at 620 kpa (90 psia) and 121 C (250 F) on ignition and combustion resistance was determined. As expected, <span class="hlt">aged</span> polymers were less ignitable and combustible (had higher AlTs and lower heats of combustion). Special attention was given to Neoflon CTFE. More specifically, the effect of process history (compression versus extrusion molding) and percent crystallinity (quick- versus slow-quenched) on the AIT, heat of combustion, and impact sensitivity of Neoflon CTFE was investigated. Results show the AIT, heat of combustion, and impact sensitivity to be essentially independent of Neoflon CTFE process history and structure.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('https://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pmcentrez&artid=2613599','PMC'); return false;" href="https://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pmcentrez&artid=2613599"><span>Adrenocorticotropic hormone stimulation <span class="hlt">tests</span> in healthy foals from birth to 12 weeks of <span class="hlt">age</span></span></a></p> <p><a target="_blank" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pmc">PubMed Central</a></p> <p>Wong, David M.; Vo, Dai Tan; Alcott, Cody J.; Stewart, Allison J.; Peterson, Anna D.; Sponseller, Brett A.; Hsu, Walter H.</p> <p>2009-01-01</p> <p>The purpose of this study was to investigate total baseline plasma cortisol and adrenocorticotropic hormone (ACTH) concentrations, and ACTH-stimulated cortisol concentrations in foals from birth to 12 wk of <span class="hlt">age</span>.

Each foal received cosyntropin (0.1 μg/kg) intravenously. Plasma cortisol concentrations were measured before (baseline), and 30, and 60 min after cosyntropin administration at birth and at 3, 5, 7, 10, 14, 21, 28, 42, 56, and 84 d of <span class="hlt">age</span>. Compared with baseline, cortisol concentration increased significantly 30 min after administration of cosyntropin on all days. Cortisol concentration was highest at birth, measured at 30 and 60 min after cosyntropin administration, compared with all other days. With the exception of birth measurements, cortisol concentration was significantly higher on day 84, measured at 30 and 60 min after cosyntropin administration, when compared with all other days. Baseline plasma ACTH was lowest at birth when compared with concentrations on days 2, 3, 4, 5, 7, 10, 14, 42, 56, and 84.

These data should serve as a reference for the ACTH stimulation <span class="hlt">test</span> in foals and should be useful in subsequent studies to evaluate the hypothalamic-pituitary-adrenal axis in healthy and critically ill foals.

We conducted three systematic reviews of the literature to identify studies of menopause prediction based on AMH, AFC, or mother's ANM, corrected for baseline <span class="hlt">age</span>. Six studies selected in the search for AMH all consistently demonstrated AMH as being capable of predicting ANM (hazard ratio, 5.6-9.2). The sole study reporting on mother's ANM indicated that AMH was capable of predicting ANM (hazard ratio, 9.1-9.3). Two studies provided analyses of AFC and yielded conflicting results, making this marker less strong. AMH is currently the most promising marker for ANM prediction. The predictive capacity of mother's ANM demonstrated in a single study makes this marker a promising contributor to AMH for menopause prediction. Models, however, do not predict the extremes of menopause <span class="hlt">age</span> very well and have wide prediction interval. These markers clearly need improvement before they can be used for individual prediction of menopause in the clinical setting. Moreover, potential limitations for such use include variations in AMH assays used and a lack of correction for factors or diseases affecting AMH levels or ANM. Future studies should include women of a broad <span class="hlt">age</span> range (irrespective of cycle regularity) and should base predictions on repeated AMH measurements.

These field activities will be conducted according to the guidelines established in DOE/RL-2010-29, 100-NR-2 Design Optimization Study, hereafter referred to as the DOS. The DOS supports the Federal Facility Agreement Consent Order (EPA et al., 1989), Milestone M-16-06-01, and 'Complete Construction of a Permeable Reactive Barrier at 100-N.' Injections of apatite precursor chemicals will occur at an equal distance intervals on each end of the existing PRE to extend the PRB from the existing 91 m (300 ft) to at least 274 m (900 ft). Field <span class="hlt">testing</span> at the 100-N Area Apatite Treatability <span class="hlt">Test</span> Site, as depicted on Figure 1, shows that the barrier is categorized by two general hydrologic conceptual models based on overall well capacity and contrast between the Hanford and Ringold hydraulic conductivities. The upstream portion of the original barrier, shown on Figure 1, is characterized by relatively low overall well specific capacity. This is estimated from well development data and a lower contrast in hydraulic conductivity between the Hanford formation and Ringold Formations. Comparison of <span class="hlt">test</span> results from these two locations indicate that permeability contrast between the Hanford formation and Ringold Formation is significantly less over the upstream one-third of the barrier.

Three outlines are the basis of the pyramid that comprehend the research as a whole: authors' previous work, which has provided the public to self-check their own sunglasses regarding the ultraviolet protection compatible to their category; Brazilian national survey in order to improve nationalization of sunglasses standards; and studies conducted on revisiting requirements of worldwide sunglasses standards, in which this work is inserted. It is still controversial on the literature the ultraviolet (UV) radiation effects on the ocular media, but the World Health Organization has established safe limits on the exposure of eyes to UV radiation based on the studies reported in literature. Sunglasses play an important role in providing safety, and their lenses should provide adequate UV filters. Regarding UV protection for ocular media, the resistance-to-irradiance <span class="hlt">test</span> for sunglasses under many national standards requires irradiating lenses for 50 uninterrupted hours with a 450 W solar simulator. This artificial <span class="hlt">aging</span> <span class="hlt">test</span> may provide a corresponding evaluation of exposure to the sun. Calculating the direct and diffuse solar irradiance at a vertical surface and the corresponding radiant exposure for the entire year, we compare the latter with the 50-h radiant exposure of a 450 W xenon arc lamp from a solar simulator required by national standards. Our calculations indicate that this stress <span class="hlt">test</span> is ineffective in its present form.

All participants were subjected to vHIT with horizontal semicircular canal (HSCC). vHIT with vertical canal (posterior and anterior semicircular canal [PSCC and ASCC]) additionally was performed in 434 participants. The mean vestibulo-ocular reflex (VOR) gain was maintained in patients in the HSCC at below 70 years (1.025 ± 0.08) and in the vertical canal at below 80 years (PSCC: 0.965 ± 0.12, ASCC: 0.975 ± 0.14). However, the decrease of VOR gain was significant in patients over 70 years in the HSCC (0.978 ± 0.35, P < .001) and in patients over 80 years in the vertical canal (PSCC: 0.828 ± 0.16, ASCC: 0.851 ± 0.13, P < .001). In addition, a VOR gain of rightward impulse was higher than the leftward impulse, but there was no difference based on the direction of impulse in the vertical impulse <span class="hlt">test</span>. VOR gain declines with increasing <span class="hlt">age</span>, over 70 years on the horizontal canal, and over 80 years on the vertical canal. Additionally, horizontal VOR gain of rightward impulse was higher than the leftward impulse in right-eye recordings only, but the vertical canal showed no difference of gain according to the direction of impulse. 2b.

This study examined <span class="hlt">test</span>-retest reliability of isokinetic knee strength measurements in children <span class="hlt">aged</span> 8 to 10 years and defined limits for the minimum difference (MD) in strength that indicates a clinically important change. Isokinetic knee strength measurements (using the Biodex System 4) in children will provide reliable results. Descriptive laboratory study. In 22 healthy children, 5 maximal concentric (CON) knee extensor (KE) and knee flexor (KF) contractions at 2 angular velocities (60 deg/s and 180 deg/s) and 5 maximal eccentric (ECC) KE/KF contractions at 60 deg/s were assessed 7 days apart. The intraclass correlation coefficient (ICC2.1) was used to examine relative reliability, and the MD was calculated on the basis of standard error of measurement. ICCs for CON KE/KF peak torque measurements were fair to excellent (range, 0.49-0.81). The MD% values for CON KE and KF ranged from 31% to 37% at 60 deg/s and from 34% to 39% at 180 deg/s. ICCs in the ECC mode were good (range, 0.60-0.70), but associated MD% values were high (>50%). There was no systematic error for CON KE/KF and ECC KE strength measurements at 60 deg/s, but systematic error was found for all other measurements. The dynamometer provides a reliable analysis of isokinetic CON knee strength measurements at 60 deg/s in children <span class="hlt">aged</span> 8 to 10 years. Measurements at 180 deg/s and in the ECC mode were not reliable, indicating a need for more familiarization prior to <span class="hlt">testing</span>. The MD values may help clinicians to determine whether a change in knee strength is due to error or intervention.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://hdl.handle.net/2060/20120001765','NASA-TRS'); return false;" href="http://hdl.handle.net/2060/20120001765"><span>Solid Propulsion Systems, Subsystems, and Components Service Life <span class="hlt">Extension</span></span></a></p> <p><a target="_blank" href="http://ntrs.nasa.gov/search.jsp">NASA Technical Reports Server (NTRS)</a></p> <p>Hundley, Nedra H.; Jones, Connor</p> <p>2011-01-01</p> <p>The service life <span class="hlt">extension</span> of solid propulsion systems, subsystems, and components will be discussed based on the service life <span class="hlt">extension</span> of the Space Transportation System Reusable Solid Rocket Motor (RSRM) and Booster Separation Motors (BSM). The RSRM is certified for an <span class="hlt">age</span> life of five years. In the aftermath of the Columbia accident there were a number of motors that were approaching the end of their five year service life certification. The RSRM Project initiated an assessment to determine if the service life of these motors could be extended. With the advent of the Constellation Program, a flight <span class="hlt">test</span> was proposed that would utilize one of the RSRMs which had been returned from the launch site due to the expiration of its five year service life certification and twelve surplus Chemical Systems Division BSMs which had exceeded their eight year service life. The RSRM <span class="hlt">age</span> life tracking philosophy which establishes when the clock starts for <span class="hlt">age</span> life tracking will be described.

The current study examined verbal memory performance using the Rey Auditory Verbal Learning <span class="hlt">Test</span> (RAVLT) in a pediatric TBI sample. Verbal memory abilities as well as the effect of <span class="hlt">age</span> at-<span class="hlt">testing</span> on performance were examined. A sample of 67 children following severe TBI (<span class="hlt">age</span> average = 12.3 ± 2.74) and 67 matched controls were evaluated using the RAVLT. <span class="hlt">Age</span> effect at assessment was examined using two <span class="hlt">age</span> groups: above and below 12 years of <span class="hlt">age</span> during evaluation. Differences between groups were examined via the 9 RAVLT learning trials and the 7 composite scores conducted out of them. Children following TBI recalled significantly less words than controls on all RAVLT trials and had significantly lower scores on all composite scores. However, all of these scores fell within the low average range. Further analysis revealed significantly lower than average performance among the older children (above 12 years), while scores of the younger children following TBI fell within average limits. To conclude, verbal memory deficits among children following severe TBI demonstrate an <span class="hlt">age-at-testing</span> effect with more prominent problems occurring above 12 years at the time of evaluation. Yet, <span class="hlt">age</span>-appropriate performance among children below 12 years of <span class="hlt">age</span> may not accurately describe memory abilities at younger <span class="hlt">ages</span> following TBI. It is therefore recommended that clinicians address child's <span class="hlt">age</span> at <span class="hlt">testing</span> and avoid using a single <span class="hlt">test</span> as an indicator of verbal memory functioning post TBI.</p> </li> </ol> <div class="pull-right"> <ul class="pagination"> <li><a href="#" onclick='return showDiv("page_1");'>«</a></li> <li><a href="#" onclick='return showDiv("page_21");'>21</a></li> <li><a href="#" onclick='return showDiv("page_22");'>22</a></li> <li><a href="#" onclick='return showDiv("page_23");'>23</a></li> <li><a href="#" onclick='return showDiv("page_24");'>24</a></li> <li class="active"><span>25</span></li> <li><a href="#" onclick='return showDiv("page_25");'>»</a></li> </ul> </div> </div><!-- col-sm-12 --> </div><!-- row --> </div><!-- page_25 --> <center> <div class="footer-extlink text-muted"><small>Some links on this page may take you to non-federal websites.
