Fatigue Strength of Hot Rolled Deformed Reinforcing Bars

FATIGUE TESTS ON #5, 8, AND 10 REINFORCING BARS (16, 25, AND 32 MM DIAMETER, RESPECTIVELY) WITH NOMINAL YIELD STRENGTHS OF 40, 60 AND 75 KSI (2800, 4200, AND 5300 KGF/CM SQUARED) ARE REPORTED. TESTS WERE CARRIED OUT ON REINFORCED CONCRETE BEAMS CONTAINING ONE SUCH BAR AND ON SPECIMENS MACHINED FROM THE BARS. ALTHOUGH THE FATIGUE STRENGTH OF THE MACHINED SPECIMENS VARIED DIRECTLY AS THE ULTIMATE TENSILE STRENGTH OF THE BARS, THE FATIGUE STRENGTHS OF THE BARS THEMSELVES WERE ESSENTIALLY CONSTANT AND EQUAL TO 30 KSI (2100 KGF/CM SQUARED) FOR A ZERO TO MAXIMUM TENSION CYCLE. IT IS SUGGESTED THAT THIS MAY BE CAUSED BY THE DECARBURIZED OUTER SURFACE OF THE BARS AND STRESS CONCENTRATIONS AT THE BASE OF THE DEFORMATIONS. /AUTHOR/
The New Indices of Religious Orientation Revised (NIROR): A Study among Canadian Adolescents Attending a Baptist Youth Mission and Service Event

This study explores the properties of the New Indices of Religious Orientation Revised (NIROR) among a sample of 521 Canadian adolescents attending a Baptist youth mission and service event, ranging in age from 12 to 19 years. This revision simplified the language of the original instrument to increase its accessibility among young people. The data support the internal consistency reliability and construct validity of the three revised nine-item scales designed to operationalise extrinsic religious orientation, intrinsic religious orientation, and quest religious orientation.
Ocean Acidification and the Loss of Phenolic Substances in Marine Plants

Rising atmospheric CO2 often triggers the production of plant phenolics, including many that serve as herbivore deterrents, digestion reducers, antimicrobials, or ultraviolet sunscreens. Such responses are predicted by popular models of plant defense, especially resource availability models which link carbon availability to phenolic biosynthesis. CO2 availability is also increasing in the oceans, where anthropogenic emissions cause ocean acidification, decreasing seawater pH and shifting the carbonate system towards further CO2 enrichment. Such conditions tend to increase seagrass productivity but may also increase rates of grazing on these marine plants. Here we show that high CO2 / low pH conditions of OA decrease, rather than increase, concentrations of phenolic protective substances in seagrasses and eurysaline marine plants. We observed a loss of simple and polymeric phenolics in the seagrass Cymodocea nodosa near a volcanic CO2 vent on the Island of Vulcano, Italy, where pH values decreased from 8.1 to 7.3 and pCO2 concentrations increased ten-fold. We observed similar responses in two estuarine species, Ruppia maritima and Potamogeton perfoliatus, in in situ Free-Ocean-Carbon-Enrichment experiments conducted in tributaries of the Chesapeake Bay, USA. These responses are strikingly different than those exhibited by terrestrial plants. The loss of phenolic substances may explain the higher-than-usual rates of grazing observed near undersea CO2 vents and suggests that ocean acidification may alter coastal carbon fluxes by affecting rates of decomposition, grazing, and disease. Our observations temper recent predictions that seagrasses would necessarily be “winners” in a high CO2 world.
Alteration of cell-wall porosity is involved in osmotic stress-induced enhancement of aluminium resistance in common bean (Phaseolus vulgaris L.)

Aluminium (Al) toxicity and drought are the two major abiotic stress factors limiting common bean production in the tropics. Using hydroponics, the short-term effects of combined Al toxicity and drought stress on root growth and Al uptake into the root apex were investigated. In the presence of Al stress, PEG 6000 (polyethylene glycol)-induced osmotic (drought) stress led to the amelioration of Al-induced inhibition of root elongation in the Al-sensitive genotype VAX 1. PEG 6000 (>> PEG 1000) treatment greatly decreased Al accumulation in the 1 cm root apices even when the roots were physically separated from the PEG solution using dialysis membrane tubes. Upon removal of PEG from the treatment solution, the root tips recovered from osmotic stress and the Al accumulation capacity was quickly restored. The PEG-induced reduction of Al accumulation was not due to a lower phytotoxic Al concentration in the treatment solution, reduced negativity of the root apoplast, or to enhanced citrate exudation. Also cell-wall (CW) material isolated from PEG-treated roots showed a low Al-binding capacity which, however, was restored after destroying the physical structure of the CW. The comparison of the Al3+, La3+, Sr2+, and Rb+ binding capacity of the intact root tips and the isolated CW revealed the specificity of the PEG 6000 effect for Al. This could be due to the higher hydrated ionic radius of Al3+ compared with other cations (Al3+ >> La3+ > Sr2+ > Rb+). In conclusion, the results provide circumstantial evidence that the osmotic stress-inhibited Al accumulation in root apices and thus reduced Al-induced inhibition of root elongation in the Al-sensitive genotype VAX 1 is related to the alteration of CW porosity resulting from PEG 6000-induced dehydration of the root apoplast.
Loss of the CONSTITUTIVE PHOTOMORPHOGENIC9 Signalosome Subunit 5 Is Sufficient to Cause the cop/det/fus Mutant Phenotype in Arabidopsis

The COP9 signalosome (CSN) was originally identified based on the constitutively photomorphogenic/de-etiolated/fusca (cop/det/fus) mutants from Arabidopsis thaliana. CSN is evolutionary conserved, and its subunit 5 (CSN5) mediates the deconjugation of NEDD8 from the cullin subunit of E3 ubiquitin ligases (deneddylation). Here, we report on Arabidopsis mutants deficient in CSN5 function. We show that these mutants are phenotypically indistinguishable from the previously described cop/det/fus mutants of other CSN subunits. However, we also show that these mutants retain the CSN complex (lacking CSN5), and this finding is in contrast with the previously described CSN subunit mutants, which lack the CSN complex. We therefore conclude that loss of CSN5 as part of CSN is sufficient to cause the cop/det/fus mutant phenotype. Furthermore, we show that mutants defective in CSN5 as well as mutants defective in CSN are unable to deneddylate the Arabidopsis cullins AtCUL1, AtCUL3A, and AtCUL4. Because these are representative cullin subunits of the three cullin-containing E3 families present in Arabidopsis, we postulate that the cop/det/fus mutant phenotype may be the result of the defects caused by impaired CSN5-dependent deneddylation of cullin-containing E3s.
Contextual Bitext-Derived Paraphrases in Automatic MT Evaluation

In this paper we present a novel method for deriving paraphrases during automatic MT evaluation using only the source and reference texts, which are necessary for the evaluation, and word and phrase alignment software. Using target language paraphrases produced through word and phrase alignment a number of alternative reference sentences are constructed automatically for each candidate translation. The method produces lexical and low-level syntactic paraphrases that are relevant to the domain in hand, does not use external knowledge resources, and can be combined with a variety of automatic MT evaluation system.
Association between Severity of Cannabis Dependence and Depression

Objective. The aim of the current study was to investigate the relationship between self-reported severity of cannabis dependence and symptoms of depression. Method. The lifetime diagnoses of depression and cannabis misuse (abuse and/or dependence) were obtained from 50 participants recruited from the general community, using a self-completed diagnostic interview (CIDI-Auto 2.1). The lifetime severity of cannabis dependence was established using a standard questionnaire, Severity of Dependence Scale (SDS). Results. Of the 19 participants with mental illness diagnoses, 14 (74%) reported depression symptoms. The 14 participants with depression diagnoses had significantly more cannabis misuse diagnoses and significantly higher SDS scores compared to those without mental illness diagnoses (N = 31). SDS scores significantly predicted presence or absence of CIDI depression diagnoses with a 69% overall rate of cor-rect predictions. As SDS scores increased the odds of classification into depressed versus non-depressed groups was 1.3 (95% C.I. 1.02-1.57). Conclusion. The presence of lifetime depression symptoms is associated with higher lifetime severity of cannabis dependence and more lifetime cannabis misuse symptoms in otherwise healthy research vol-unteers.
Peripheral Refraction With and Without Contact Lens Correction

Purpose. Peripheral refractive error degrades the quality of retinal images and has been hypothesized to be a stimulus for the development of refractive error. The purpose of this study was to investigate the changes in refractive error across the horizontal visual field produced by contact lenses (CLs) and to quantify the effect of CLs on peripheral image blur. Methods. A commercial Shack-Hartmann aberrometer measured ocular wavefront aberrations in 5° steps across the central 60° of visual field along the horizontal meridian before and after CLs correction. Wavefront refractions for peripheral lines-of-sight were based on the full elliptical pupil encountered in peripheral measurements. Curvature of field is the change in peripheral spherical equivalent relative to the eye's optical axis. Results. Hyperopic curvature of field in the naked eye increases with increasing amounts central myopic refractive error as predicted by Atchison (2006). For an eccentricity of E degrees, field curvature is approximately E percent of foveal refractive error. Rigid gas permeable (RGP) lenses changed field curvature in the myopic direction twice as much as soft CLs (SCLs). Both of these effects varied with CLs power. For all lens powers, SCL cut the degree of hyperopic field curvature in half whereas RGP lenses nearly eliminated field curvature. The benefit of reduced field curvature was partly offset by increased oblique astigmatism. The net reduction of retinal blur because of CLs is approximately constant across the visual field. Conclusions. Both SCL and RGP lenses reduced the degree of hyperopic field curvature present in myopic eyes, with RGP lenses having greater effect. The tradeoff between field curvature and off-axis astigmatism with RGP lenses may limit their effectiveness for control of myopia progression. These results suggest that axial growth mechanisms that depend on retinal image quality will be affected more by RGP than by SCL lenses.
Post-traumatic stress symptoms in relatives in the first weeks after severe traumatic brain injury

Introduction: Severe traumatic brain injury (STBI) can cause psychological stress in proxies in the long-term. This study assessed post-traumatic stress (PTS) symptoms in proxies of survivors of STBI in the short-term and investigated stress-associated factors. Methods: Prospective cross-sectional study, conducted at three Swiss trauma centres over 1 year. Patient and proxy demographics, trauma data including Glasgow Coma Scale (GCS) and management data were collected. The proxies’ PTS symptoms were assessed by applying the Impact of Event Scale–Revised (IES-R), once in the first month after the accident (median: 11 days). Results: Sixty-nine proxies were included; 52 proxies were female (77.8%). Mean IES-R sum score for intrusions was 13.38 (SD = 7.26), for avoidance 8.91 (SD = 5.94), and for hyperarousal 9.07 (SD = 6.75). Clinically significant PTS symptoms were observed in 36 proxies (52.2%); mean IES-R sum scores were significantly higher in women. IES-R sub-scale values were inversely related with GCS at the scene of the accident and on hospital admission. Conclusions: More than half of proxies had clinically significant PTS symptoms shortly after their relative's accident. More severe PTS symptoms were found in women and in proxies of patients with poorer initial GCS scores. Further research into risk groups in the short- and long-term and the long-term impact on patients of PTS syndrome in proxies is warranted.
The Impact of Age vs. Life Experience on the Gender Role Attitudes of Women in Different Cohorts

ABSTRACT Much research has concluded that the gender role attitudes of older women are more traditional in orientation. This line of research, however, has often confounded the impact of age and cohort. Consequently, cohort differences in life experiences have not been systematically explored. This study addresses the relationship between age and gender role attitudes, taking into account the potential mediating effects of life experiences and controlling for cohort. The conclusions suggest that the impact of age on gender role attitudes is not as strong as might be expected. Rather, the results show that the life experiences of different cohorts are better predictors of gender role attitudes among older women, though such experiences do not have the same impact on all women.

Objective To assess whether traditional measures of access to health care (distance and travel time to a facility) and non-traditional measures (social and financial support indicators) are associated with mortality among children under 5 years of age in the Gambia. Methods We conducted a case–control study in a population under demographic surveillance. Cases (n = 140) were children under 5 years of age who died between 31 December 2003 and 30 April 2006. Each case was matched in age and sex to five controls (n = 700). Information was gathered by interviewing primary caregivers. The data were analysed using conditional logistic regression. Findings Of traditional measures of access, only rural versus urban/periurban residence was important: children from rural areas were more likely to die (OR: 4.9; 95% confidence interval, CI: 1.2–20.2). For non-traditional measures, children were more likely to die if their primary caregivers lacked help with meal preparation were unable to cut spending for health care (OR: 2.5; 95% CI: 1.5–4.2) or had to carry out odd jobs to pay for the care (OR: 3.4; 95% CI: 2.1–5.5). A protective effect was observed when the caregiver had other children to care for (OR: 0.2; 95% CI: 0.1–0.5). Conclusion Improving access to health-care for children in the Gambia and similar settings is not simply a matter of reducing travel time and distance to a health facility, but requires improvements in caregivers' support networks and their access to the financial resources they need.

Motivation for tattoo removal.

Motivations for removal of tattoos may be similar among different populations. Our data support the Boston, Mass, report 1 that tattoos applied impulsively in youth are regretted in later years. In a survey of 68 patients, 44 men and 24 women, requesting tattoo removal at the Bridgend Laser Clinic, Bridgend Mid Glamorgan, Wales, 2 we found that 71% of patients had tattoos applied before 18 years of age. Forty-five percent of patients had applications because tattoos were perceived as fashionable, 22% because of peer pressure, 7% through "sheer stupidity," and 6% because they were in love. Only 13% were under the influence of alcohol or drugs at the time. Ten percent of patients regretted the tattoo immediately and 28% voiced remorse within the first month. The primary motive for removal of a tattoo was an overwhelming desire to improve self-esteem (48%), followed by removal of a socially stigmatizing and discrediting
Pancreatic Neuroendocrine Tumors and EMT Behavior Are Driven by the CSC Marker DCLK1

Doublecortin-like kinase 1 (DCLK1), a marker for intestinal and pancreatic cancer stem cells, is highly expressed in neuroblastomas. This study was conducted to assess DCLK1 expression levels in pancreatic neuroendocrine tumor (PNET) tissues and to explore the roles of this molecule in clinical tissue from multiple PNET patients, cells (BON1, QGP1, and CM) and tumor xenografts. Immunohistochemically, all PNET tissues highly and diffusely expressed DCLK1 as a full-length isoform, identical to that detected in primary liver NETs. A DCLK1-overexpressing PNET cell line (QGP1-DCLK1) exhibited epithelial–mesenchymal transition (EMT)-related gene signatures, and robust upregulation of Slug (SNAI2), N-Cadherin (CDH2), and Vimentin (VIM) was validated by real-time PCR and immunoblotting. QGP1-DCLK1 cells had increased cell migration in a wound-healing assay and formed significantly larger xenograft tumors in nude mice. The factors involved in the formation of the fast-growing tumors included p-FAK (on Tyr925), p-ERK1/2, p-AKT, Paxillin, and Cyclin D1, which upon knockdown or pharmacologic inhibition of DCLK1 abolished the expression of these molecules. In conclusion, robust and ubiquitous expression of DCLK1 was first demonstrated here in human PNET tissue specimens and cells. DCLK1 characterized the PNET cell behavior, inducing p-FAK/SLUG-mediated EMT. These findings suggest the possibility of developing novel therapeutic strategies against PNETs by targeting DCLK1. Implications: Evidence here reveals that human PNETs diffusely and robustly express the cancer stem cell marker DCLK1, which drives SLUG-mediated EMT, and suggests that NETs share biological features for druggable targets with other tumors, including neuroblastoma that also highly expresses DCLK1.

Rejection Sensitivity, Perceived Power, and HIV Risk in the Relationships of Low-Income Urban Women

The psychological processes associated with HIV infection in long-term relationships differ from those operative in casual sexual encounters, and relatively little research has considered the aspects of personality applicable in the ongoing heterosexual relationships in which women are at greatest risk. Sensitivity to rejection has been linked with efforts to prevent rejection at a cost to the self and, therefore, may be relevant to the health risks that many women incur in relationships. We examined the association of rejection sensitivity with women’s sexual risk behavior in a sample of women at heightened risk for HIV exposure. Women in long-term heterosexual relationships (N = 159) were recruited for study participation in the hospital emergency room serving a low-income neighborhood in New York City, in 2001–2003. Rejection sensitivity and known HIV risk factors were assessed using verbally administered questionnaires. Rejection sensitivity was associated with lower perceived relationship power and, in turn, more frequent unprotected sex with a partner perceived to be at risk for HIV. These results held when controlling for other HIV risk factors including partner violence, economic dependence, and substance use. Understanding the association of rejection concerns with lower perceived personal power in relationships may be important for HIV prevention.
ANTIPNEUMOCOCCIC IMMUNITY REACTIONS IN INDIVIDUALS OF DIFFERENT AGES

1. The incidence of pneumococcidal power of the whole defibrinated blood in human beings has been shown to vary with age. The age distribution of other type-specific antibodies varies similarly, insofar as they are frequent enough to be compared or technically demonstrable. 2. The incidence of pneumococcidal power of the whole defibrinated blood for Type I, Type II, and Type III differs. Type I is the rarest, Type II is the most frequent, and Type III is of intermediate frequency. The type-specific antibodies responsible for the other tests employed show a similar relative frequency in regard to Types I and II, but some variation in regard to Type III. 3. The skin reactions to the acetic acid-predpitable proteins and autolysates of the pneumococci are negative or rarely positive in infants, infrequently positive in childhood, and positive in a high percentage of adults.
Optimal Dynamic Remapping of Data Parallel Computations

A large class of data parallel computations is characterized by a sequence of phases, with phase changes occurring unpredictably. Dynamic remapping of the workload to processors may be required to maintain good performance. The problem considered, for which the utility of remapping and the future behavior of the workload are uncertain, arises when phases exhibit stable execution requirements during a given phase, but requirements change radically between phases. For these situations, a workload assignment generated for one phase may hinder performance during the next phase. This problem is treated formally for a probabilistic model of computation with at most two phases. The authors address the fundamental problem of balancing the expected remapping performance gain against the delay cost, and they derive the optimal remapping decision policy. The promise of the approach is shown by application to multiprocessor implementations of an adaptive gridding fluid dynamics program and to a battlefield simulation program. >
Silhouette and stereo fusion for 3D object modeling

We present a new approach to high quality 3D object reconstruction. Starting from a calibrated sequence of color images, the algorithm is able to reconstruct both the 3D geometry and the texture. The core of the method is based on a deformable model, which defines the framework where texture and silhouette information can be fused. This is achieved by defining two external forces based on the images: a texture driven force and a silhouette driven force. The texture force is computed in two steps: a multistereo correlation voting approach and a gradient vector flow diffusion. Due to the high resolution of the voting approach, a multigrid version of the gradient vector flow has been developed. Concerning the silhouette force, a new formulation of the silhouette constraint is derived. It provides a robust way to integrate the silhouettes in the evolution algorithm. As a consequence, we are able to recover the apparent contours of the model at the end of the iteration process. Finally, a texture map is computed from the original images for the reconstructed 3D model.
Transfer of assembly operations to new workpiece poses by adaptation to the desired force profile

In this paper we propose a new algorithm that can be used for adaptation of robot trajectories in automated assembly tasks. Initial trajectories and forces are obtained by demonstration and iteratively adapted to specific environment configurations. The algorithm adapts Cartesian space trajectories to match the forces recorded during the human demonstration. Experimentally we show the effectiveness of our approach on learning of Peg-in-Hole (PiH) task. We performed our experiments on two different robotic platforms with workpieces of different shapes.
From Onions to Shallots: Rewarding Tor Relays with TEARS

Abstract : The Tor anonymity network depends on volunteers to operate relays, and might offer higher bandwidth with lower response latencies if more users could be incentivized to contribute relay bandwidth.We introduce TEARS, a system rewarding useful service with traffic priority. TEARS audits relays and rewards them with anonymous coins called Shallots, proportionally to bandwidth contributed. Shallots may be re- deemed anonymously for PriorityPasses, which in turn may be presented to relays to request traffic priority. The PriorityPass construction enables relays to prevent double spending locally without leaking information. Unlike previous incentive proposals, TEARS incorporates transparent and distributed banking using protocols from distributed digital cryptocurrency systems like Bitcoin. Shallots are publicly-veri able, minimizing reliance on and trust in banking authorities, making them auditable while naturally distributing bank functionality and associated overhead. Further, these distributed banking protocols resist denial-of-service at- tacks and can recover from catastrophic failures. TEARS may either be deployed in the existing Tor network or operate alongside it.
