Improved Marine 4D Repeatability Using an Automated Vessel, Source and Receiver Positioning System

SUMMARY A new automated and integrated, vessel, source, and receiver control system has been developed to improve the accuracy and repeatability of 4D surveys. The new control system replaces operator intervention with automated updates to vessel, source, and streamer steering devices from positioning information from all in-sea equipment. This has lead to a step change in the accuracy of source repeatability (2.5-m repeat accuracy for 95% of shotpoints), and has also improved the ability to repeat receiver positions.
Can human patient simulators be used in physiotherapy education

Purpose: The purpose of this study was to review the evidence for the use of human patient simulators in physiotherapy education. Method: A review of the physiotherapy literature was undertaken. Due to the lack of studies found the search was expanded to include health professional education. Exclusion criteria were then applied to the identified literature and critical appraisal undertaken. Results: Due to the differences in methodology employed in the studies identified a meta-analysis could not be performed. The studies identified repeat practice and the ability to control the learning environment as positive aspects for learning using human patient simulators. In medical education psychomotor skills improved when simulators where used. Conclusions: Conclusions were not able to be drawn regarding whether the use of human patient simulators leads to improved patient management in a clinical environment especially in the field of physiotherapy. A controlled study investigating cardiorespiratory physiotherapy clinical performance is recommended to determine whether human patient simulators should be used in physiotherapy education.

Alternate Derivation of the Critical Value of the Frank-Kamenetskii Parameter in Cylindrical Geometry

Abstract Noether’s theorem is used to determine first integrals admitted by a generalised Lane- Emden equation of the second kind modelling a thermal explosion. These first integrals exist for rectangular and cylindrical geometry. For rectangular geometry the first integrals show the symmetry of the temperature gradients at the rectangular walls. For a cylindrical geometry the first integrals show the dependence of the critical parameter on the temperature gradient at the cylinder wall. The well known critical value for the Frank-Kamenetskii parameter, δ = 2, is obtained in a very natural way.

Clinical and Laboratory Characteristics of Herpes Simplex Encephalitis in Children in Qena Governorate , Egypt

Background: Herpes encephalitis in children entails a significant risk of mortality and morbidity. The diagnosis of herpes simplex virus (HSV) encephalitis has been markedly facilitated by the availability of assays that amplify viral DNA to detectable levels by using polymerase chain reaction (PCR). This study aimed to obtain the incidence of HSV encephalitis in Qena Governorate, Egypt, to highlight the role of different investigation studies in diagnosis and prognosis of herpetic encephalitis and to highlight the role of PCR in detection of HSV. Methods: This study was conducted on 50 patients suspected to have viral encephalitis. All were subjected to complete history and examination, cerebrospinal fluid (CSF) examination, electroencephalogram (EEG), CT brain and PCR amplification for HSV DNA by real-time PCR using SYBR Green I Dye as the detection signal. Results: Encephalitis was more detected in cases less than 1 year (52.2%), males, in rural (61.3%) and in lower socioeconomic state (55%) than others. Seizures (60%) and focal neurological findings (46%) were the most common presentations. HSV DNA was detected by PCR in CSF samples from 28 patients (56%). Conclusions: PCR may be one of the sensitive and specific investigative methods for laboratory diagnosis of HSV encephalitis. The incidence of HSV-induced encephalitis in children in Qena governorate
Benefits of laptop computer ergonomics education to graduate students

Laptop computers are used more often than desktop computers, especially among graduate students. Many common laptop habits can have severe physiological effects on the user ranging from eye strain, poor posture, upper extremity pain, and overuse injuries. Thus, it is important to educate students on the best ergonomic position to use laptops. This study investigates the efficacy of a laptop ergonomic education session and its effects on graduate students’ knowledge and behaviors regarding proper laptop use. A convenience sample of control and experimental groups was used and consisted of 83 occupational therapy (OT), 63 physical therapy (PT), and 26 nurse anesthesia (NA) graduate students. The sample size was 172, with 94 graduate students in the control group and 78 graduate students in the experimental. All study participants completed an initial ergonomics questionnaire. The experimental group was given an ergonomics education session following the questionnaire. Approximately 4 weeks after both groups completed the initial questionnaire; a follow up questionnaire was administered. Results showed that subjects demonstrated a statistically significant improvement in ergonomics knowledge after they completed the ergonomic educational session. Some participants reported making adaptations to laptop positioning and equipment use following the educational session. Thus, participating in ergonomic education can positively influence awareness of body mechanics relative to laptop workstation design.
Emotional hybrids and Functional Cerebral Asymmetries: The role of the left and right hemispheres in processing unseen emotional content

Functional cerebral asymmetries have been demonstrated for emotional face perception but a conflicting pattern of results emerges from the literature. Previous studies suggest discrepancies may be driven by the spatial frequency content of emotional stimuli and also participant’s awareness. The current study investigated this using emotional hybrid faces which are created by combining low spatial frequency content of an emotional face with high spatial frequency information of a neutral face. An affective priming paradigm was employed to investigate whether emotional content conveyed by low spatial frequencies was sufficient to affect identification of target emotional hybrids; when presented to each cerebral hemisphere using the divided visual half-field technique. In Experiment 1, participants viewed neutral or emotional primes followed by emotional targets on congruent trials or neutral targets on incongruent trials, presented in each visual half-field. Participants indicated whether the target face was emotional or neutral. Experiments 2 and 3 adopted an expression identification task, requiring participants to identify the emotion displayed. The results revealed fearful faces were identified more accurately by the left hemisphere in Experiment 1 and that emotional congruency of prime and target had a positive effect on performance. Experiments 2 and 3 however, showed a general advantage for the right hemisphere and an adverse effect of emotional congruency. It was concluded that contrast effects accounted for the adverse effects of congruency in the later experiments and differences between Experiments 1 and Experiments 2 and 3 were the result of increased task difficulty in the latter. The results also suggest a general RH dominance for emotion processing as the left hemisphere advantage for fear in Experiment 1 was concluded to result from a hemispheric advantage for processing changes in the white sclera of the eye region.
Design of an Aeroelastically Tailored 10 MW Wind Turbine Rotor

This work presents an integrated multidisciplinary wind turbine optimization framework utilizing state-of-the-art aeroelastic and strutural tools, capable of simultaneous design of the outer geometry and internal structure of the blade. The framework is utilized to design a 10 MW rotor constrained not to exceed the design loads of an existing reference wind turbine. The results show that through combined geometric tailoring of the internal structure and aerodynamic shape of the blade it is possible to achieve significant passive load alleviation that allows for a 9% longer blade with an increase in AEP of 8.7%, without increasing blade mass and without significant increases in ultimate and fatigue loads on the hub and tower.
The relationship between job insecurity and well-being among Peruvian workers

The present study’s aims are twofold: to introduce job insecurity research in Peru, and to investigate the relationship between job insecurity and a broad range of well-being indicators, including optimal and impaired, and general and work-related well-being. We hypothesise that job insecurity (1) relates negatively to work-related optimal well-being (i.e., job satisfaction, career satisfaction and work engagement) and positively to work-related impaired well-being (i.e., burnout), and (2) negatively to general optimal well-being (i.e., life satisfaction) and positively to general impaired well-being (i.e., psychological distress). In 2008, we administered questionnaires to employees from eight organizations based in Metropolitan Lima, yielding a convenience sample of 651 respondents. We used hierarchical regression analyses and controlled for organizations, age, gender, job-related (e.g., occupational position) and familyrelated (e.g., financial contribution to the household) variables. Results supported our hypotheses. We conclude that job insecurity shows a strong association with impaired wellbeing. A particular strength of this study is that it is situated in Lima, Peru, and in a context of economic growth. It also contributes to understand the association of job insecurity with workrelated well-being by including rarely studied variables such as career satisfaction, work engagement and burnout.
Performance and carcass characteristics of feedlot-finished Zebu cattle in different feeding systems

The performance and characteristics of 18 carcasses of feedlot-finished Zebu cattle were evaluated over 93 days in confinement or semi-confinement systems. In the semi-confinement system, two strategies of pasture deferral were adopted, 40 days (40DD) and 80 days (80DD). The feed of animals in confinement was composed of 24% of grass silage Urochloa spp. and 76% concentrate, on dry matter, freely supplied twice daily. Grazing animals received 4 kg of animal concentrate per day. The final fasting weight of the animals in confinement (534.92 kg) was higher than that of animals semi-confined in 40DD (475.33 kg) and 80DD (460.67 kg) pastures, because of the higher daily weight gain (1.37 vs. 0.82 and 0.64 kg, respectively). Feedlot-finished animals had a greater carcass gain (0.91 kg animal-1 day-1), resulting in a higher carcass weight (296.47 kg), higher thickness of external fat (5.42 mm), weight and percentage of side cut (17.88 kg and 12.20%), and weight and percentage of fat in the carcass (74.50 kg and 25.22%). However, no difference was observed for the metric and developmental characteristics of the carcass, which allowed good quality carcasses to be obtained, independent of the strategies evaluated. Feedlot-finished Zebu cattle provide heavier and bulky carcasses, leading to higher revenue per marketed carcass.
Time constraints in design idea generation

It is generally believed that time pressure can hamper creative work. For design researchers, this belief is only one of the many time related claims that are short of any solid scientific basis. During previous years, design research has witnessed the birth of a new offspring, design idea generation research. This has lead to a range of systematic, psychologically-motivated studies that have identified principles behind a successful, efficient idea generation process. With this regard, it is surprising the effects of time constraints have not been thoroughly investigated so far. In this review paper we seek to clarify the temporal dimension in design idea generation by examining parallel time studies on various creative tasks. We start by analyzing the time constraints of design idea generation. We introduce three categories for time related effects: duration of a task, time decomposition of a task, and time pressure. For each category we review studies regarding its effect on idea generation. The main discoveries are that time decomposition can increase the productivity of idea generation, and while time pressure usually increases productivity, creativity can be compromised by both scarcity and abundance of time. We conclude by arguing that the controlled application of these time constraints can increase productivity and creativity within design idea generation.

Evolution of Mechanical Properties and Microstructures with Equivalent Strain in Pure Fe Processed by High Pressure Torsion

Pure Fe (99.96%) was processed by high pressure torsion (HPT) using disc and ring samples. When the microhardness and tensile properties are plotted against the equivalent strain, the individual properties fall well on unique single curves, level off at the equivalent strain of � 40. At the saturated level, the tensile strength of 1050 MPa and the elongation to failure of 2% are attained. Transmission electron microscopy showed that a subgrain structure containing dislocations develops at an initial stage of straining. More dislocations form within the grains and the subgrain size decreases with further straining. At the saturation stage, the average grain size reaches � 200 nm, the misorientation angle increases and some grains which are free from dislocations appear. It is suggested that at the saturation stage, a steady state condition should be established through a balance between hardening by dislocation generation and softening by recrystallization.

NERI FINAL TECHNICAL REPORT, DE-FC07-O5ID14647, OPTIMIZATION OF OXIDE COMPOUNDS FOR ADVANCED INERT MATRIX MATERIALS

In order to reduce the current excesses of plutonium (both weapon grade and reactor grade) and other transuranium elements, a concept of inert matrix fuel (IMF) has been proposed for an uranium free transmutation of fissile actinides which excludes continuous uranium-plutonium conversion in thermal reactors and advanced systems. Magnesium oxide (MgO) is a promising candidate for inert matrix (IM) materials due to its high melting point (2827 C), high thermal conductivity (13 W/K {center_dot} m at 1000 C), good neutronic properties, and irradiation stability However, MgO reacts with water and hydrates easily, which prevents it from being used in light water reactors (LWRs) as an IM. To improve the hydration resistance of MgO-based inert matrix materials, Medvedev and coworkers have recently investigated the introduction of a secondary phase that acts as a hydration barrier. An MgO-ZrO{sub 2} composite was specifically studied and the results showed that the composite exhibited improved hydration resistance than pure MgO. However, ZrO{sub 2} is insoluble in most acids except HF, which is undesirable for fuel reprocessing. Moreover, the thermal conductivity of ZrO{sub 2} is low and typically less than 3 W {center_dot} m{sup -1} {center_dot} K{sup -1} at 1000 C. In search for an alternativemore » composite strategy, Nd{sub 2}Zr{sub 2}O{sub 7}, an oxide compound with pyrochlore structure, has been proposed recently as a corrosion resistant phase, and MgO-Nd{sub 2}Zr{sub 2}O{sub 7} composites have been investigated as potential IM materials. An adequate thermal conductivity of 6 W {center_dot} m{sup -} 1 {center_dot} K{sup -1} at 1000 C for the MgO-Nd{sub 2}Zr{sub 2}O{sub 7} composite with 90 vol% MgO was recently calculated and reported. Other simulations proposed that the MgO-pyrochlore composites could exhibit higher radiation stability than previously reported. Final optimization of the composite microstructure was performed on the 70 vol% MgO-Nd{sub 2}Zr{sub 2}O{sub 7} composite that burnup calculations had shown to have the closest profile to that of MOX fuel. Theoretical calculations also indicated that a homogeneous 70 vol% MgO composite could achieve the desired microstructure that would result in satisfying the dual requirements of good thermal properties. « less
Who are Driving Commonality in Liquidity?

Individual stocks co-vary with each other in their liquidity, which induces a systematic, undiversifiable liquidity risk for investors. Despite the pervasive evidence on the commonality in individual liquidity within stock markets, few researches have looked at the source of commonality in liquidity. This study investigates whether correlated trading behavior of institutional investors causes co-variation in their demand of liquidity, and thus co-variation in liquidity. The empirical test using Japanese stock data shows that institutional investors prefer liquid stocks over illiquid stocks, and such preference is especially strong for foreign institutional investors. We also find that stocks heavily traded by institutional investors (both domestic and foreign institutional investors) have a higher commonality in liquidity than stocks heavily traded by individual investors. The positive relation between commonality in liquidity and co-movement in trading activity in stocks suggests that institutional investors’ correlated trading behavior does have some impact on the liquidity risk.
MACAO-VLTI First Light: Adaptive Optics at the Service of Interferometry

The Multiple Application Curvature Adaptive Optics (MACAO) programme was initiated by ESO in 1998 to fulfil the high angular resolution requirements of the VLT Interferometer (Glindemann et al., 2002) and also instruments like SINFONI (Bonnet et al., 2002) and CRIRES (Moorwood et al., 2002). After a learning phase of two years with the laboratory Curvature prototype delivered by Laplacian Optics, the ESO Adaptive Optics Department set up a project team at the beginning of 2000 for the line production of seven MACAO systems (Donaldson et al., 2000): four for VLTI, one for SINFONI, one for CRIRES and one spare. Although the AO key components are similar for these seven systems, the opto-mechanical implementations are different for the VLTI, SINFONI and CRIRES. In the following we will concentrate on the VLTI implementation. The main aim of MACAO-VLTI is to feed the VLTI with a corrected wavefront, to improve light injection efficiency in the monomode fibres. The existing Coude mirror train M8 is replaced by the corrective optics. The MACAO-VLTI Wave Front Sensor (WFS) is located just below M9 on the Coude platform (Figure 1). M9 is a dichroic that allows the wavefront sensing in the visible (transmits 0.45–0.9 μm) and reflects the wavelengths 1 to 13 μm to the recombination laboratory. Simulations done for the design reviews show that MACAO-VLTI will reach a Strehl ratio of 0.58 at 2.2 μm on bright stars (V < 10) with a seeing of 0.65 and this has been confirmed by tests in the laboratory. Limiting magnitude is evaluated at V ~ 18 which would result in a Strehl ratio slightly under ~0.1. MACAO will also operate with worse seeing (1.0 ) but the correction is less spectacular (expected Strehl ratio of 0.39). The first MACAO-VLTI system was delivered to Paranal on UT2 in April 2003, and results from the first light are shown further down in this article. The other three systems will follow at 6 month intervals. By the end of 2003 the first two systems will be available and will allow wavefront corrected beam recombination at the VLTI.
