The effects of text messaging on young novice driver performance

The current project aimed to evaluate, using the advanced driving simulator located at the Monash University Accident Research Centre, the effects of text (SMS) messaging on the driving performance of young novice drivers. Twenty participants drove on a simulated roadway which contained a number of events, including a pedestrian emerging from behind parked cars, traffic lights, cars turning right in front of the driver, a car following episode and a lane change task. The results revealed that retrieving and, in particular, sending text messages had a detrimental effect on a number of safety critical driving measures. When text messaging, drivers ability to maintain their lateral position on the road and to detect and respond appropriately to traffic signs was significantly reduced. In addition, drivers spent up to 400 per cent more time with their eyes off the road when text messaging, than when not text messaging. While there was some evidence that drivers attempted to compensate for being distracted by increasing their following distance when following a lead vehicle, drivers did not reduce their speed while distracted. Failure to do so in the real world could increase their risk of being involved in a crash as it increases the stopping distance required to avoid a collision. The practical implications of these findings are discussed. (a) For the covering record of the conference, please refer to ITRD abstract no E216954.
The Role of Internet Technology in EFL Syllabus Design

The increasing use of technology, in addition to internet based learning and teaching has created a significant change in traditional language classrooms and inevitably in language syllabus. When making practical decisions about syllabus design, the possible factors that affect the teachability of a particular syllabus such as technologisation should be taken into consideration. It has been pointed out that material, learner, and teacher are decisive factors in a language syllabus design and implementation. In this paper the role of internet technology in modifying and affecting EFL syllabus design in the light of these factors will be investigated. It is argued that internet technology can provide diversified authentic EFL material which in turn motivates learners and enables teachers to create a non-traditional teaching atmosphere.
An accurate 3-phase induction machine model including skin effect and saturations for transient studies

The aim of this paper is to present an accurate mathematical model of high power induction machines for the transient studies. The proposed model takes into consideration the skin effect and stator and rotor leakage flux paths saturation. This model has been simulated using MATLAB/spl reg/ 6.1 program. In order to validate our model on both transient and steady-state regimes, an experimental test-bed with a 3-phase, 45 kW, delta-connected induction motor has been used. Finally, the stability of the experimental numerical results will be shown to prove the performance of the proposed model.
Convoluted and interdigitated hexagon loop unit cells for frequency selective surfaces

Two types of improved hexagon loop unit cells for miniaturised frequency selective surfaces (FSSs) are presented and their transmission responses are contrasted. The measured results indicate that by interdigitating the common boundary of adjacent unit cells of FSSs, the operating bandwidth can be broadened compared with convoluted ones and the effect of size reduction is also enhanced.
Accelerated Orthodontics

Clinical orthodontics is ever dynamic branch of Dentistry. Traditionally orthodontics was always considered as aesthetic treatment of face & also needed for proper oral oral function. This treatment may take up 2–3 years of total duration. The chapter describes changing trends in this aspect wherein we speed up the treatment by various methods thus reducing the overall time duration. These modalities include alteration in bio mechanics, pharmacological, chemical & by biological means. It is also cautioned here that the clinician has to take up these changing trends based on sound clinical knowledge & evidence based applicability.
Limitations of standard coliform enumeration techniques

The coiiform indicator bacteria belong to one taxonomic group and are characterized as gram-negative, facutatively anaerobic rods, oxidase negative, and capable of producing gas from lactose within 48 hours at 35°C. They are most commonly members of the genus Escherichia, Klebsiella, Enterobacter, or Citrobactar . ' On occasion, members of the genera Hafnia and Yersinia also conform to this definition of coiiform organisms. Collectively, these bacteria are diverse in their ecology, physiology, and significance to human health. Many assume these organisms are found growing in one of two significantly different environments the warm blooded animal intestinal tract or the natural environment of

Old and at home in an intelligent environment

Due to the rapid aging of the Dutch population and aging-in-place policies, an increasing demand for suitable dwellings is to be expected. A significant contribution can be provided by domotics defined as: the advanced technological equipments and services in the domestic environment to sustain and to enhance the quality of aging in place as well as empowerment of the senior citizen (in daily life). This paper, based on literature review and qualitative and quantitative studies, (i) seeks to inform the development of domotics technology in the living environment of the older adults; (ii) provides an overview of the multiplicity of needs and attitudes of the older citizens regarding smart technology in the domestic environment; and (iii) develops recommendations to incorporate domotics in the architectural structure of the dwelling. Study to senior citizens’ needs and attitudes toward domotics is based on triangulation of cohort-group discussions, enabling techniques and in-depth interviews followed by a postal questionnaire survey. Hence, based on the identified needs, two houses, occupied by the elderly, have been upgraded by domotics. The findings indicate that needs, perceptions, environmental and personal attributes of the senior determine the attitudes towards automation. This attitude can best be described as ‘critical/positive’. Too much automation is undesirable. Ethical considerations are particularly related to professional stakeholders, especially caregivers, whereas seniors are mainly interested in the functionality of domotics. In the elderly housing, the stage of stand-alone devices is outdated. It should be focused on the networked home and the integration of domotics in the house. Innovation by addition in a traditional construction environment often results in sub-optimal solutions. The results confirm that the integration of intelligent technology in a house needs to be a synthesis of the user’s needs, technology, the living environment and healthcare.
Transition measurements on a 5 degree cone in the T4 Shock Tunnel

This report presents results from tests to detect boundary layer transition on a 572 mm long, 5 degree semi-angle cone at Mach numbers of 6.0, 6.6 and 8.8 in the T4 Shock tunnel at The University of Queensland. Results are presented for the cone with both a sharp tip and a blunted tip (nose tip radius of 5.4 mm). Results show that transition Reynolds number increases with the unit Reynolds number of the flow and that bluntness delays transition.
Lysosome

Since Christian de Duve first described the lysosome in the 1950s, it has been generally presented as a membrane-bound compartment containing acid hydrolases that enables the cell to degrade molecules without being digested by autolysis. For those working on the field of lysosomal storage disorders, the lack of one such hydrolase would lead to undegraded or partially degraded substrate storage inside engorged organelles disturbing cellular function by yet poorly explored mechanisms. However, in recent years, a much more complex scenario of lysosomal function has emerged, beyond and above the cellular ‘‘digestive’’ system. Knowledge on how the impairment of this organelle affects cell functioning may shed light on signs and symptoms of lysosomal disorders and open new roads for therapy.
A METHODOLOGY TO ESTIMATE LOAD AND NON-LOAD SHARES OF HIGHWAY PAVEMENT ROUTINE MAINTENANCE AND REHABILITATION EXPENDITURES

The present study focused on the estimation of load and non-load shares of pavement maintenance and rehabilitation expenditures. The information provides the basis for the allocation of pavement-related expenditures in a highway cost allocation study. A comprehensive database was developed in the study, and an aggregate performance approach was used based on econometric models. This approach utilizes the marginal effect of traffic loading to quantify the load and non-load shares of pavement routine maintenance and rehabilitation expenditures. The study revealed that the share of pavement damage attributable to load and non-load factors depends on several factors such as the type of improvement (routine maintenance or rehabilitation), pavement type, and other variables. For routine maintenance, the load and non-load shares were found to be 25-75 for flexible pavements, 36-64 and 60-40 for Jointed Concrete Pavements (JCP) and Continuously Reinforced Concrete (CRC) pavements, and 30-70 for composite pavements. The load and non-load fractions of rehabilitation expenditures used to repair pavement damage were found to be 30-70 for flexible pavements, 80-20 for JCP, and 40-60 for composite pavements. It is expected that the results of this study will facilitate the apportionment of pavement routine maintenance and rehabilitation expenditures in a fair and equitable manner.
Maximización de captura de energía en turbinas eólicas de velocidad variable usando control proporcional integral generalizado

This paper proposes an alternative linear control technique to maximize the energy capture in a horizontal-axis wind turbine. The proposed strategy is based on Generalized Proportional Integral (GPI) controllers supported by the active disturbance rejection approach, which allows asymptotic tracking of a rotor speed reference trajectory without exact wind turbine model knowledge. The proposed methodology controls the tip-speed ratio, via the rotor angular speed, to an optimum point at which power coefﬁcient is maximum. Several simulations are performed on a 4.8MW wind turbine benchmark model in order to validate the proposed control strategy and to compare it to a classical controller. The simulation results show that the proposed control strategies are effective in terms of power capture and robustness.

Neonatal Mice Spinal Cord Interneurons Sending Axons in Dorsal Roots

Background: Spinal cord interneurons send their axons in the dorsal root. Their antidromic fire could modulate peripheral receptors. Thus, it could control pain, other sensorial modality, or muscle spindle activity. In this study, we assessed a staining technique to analyze whether interneurons send axons in the neonate mouse’s dorsal roots. We conducted experiments in 10 Swiss-Webster mice, which ranged in age from 2 to 13 postnatal days. We dissected the spinal cord and studied it in vitro. Results: We observed interneurons in the spinal cord dorsal horn sending axons through dorsal roots. A mix of fluorochromes applied in dorsal roots marked these interneurons. They have a different morphology than motoneurons. Primary afferent depolarization in afferent terminals produces antidromic action potentials (dorsal root reflex; DRR). These reflexes appeared by stimulation of adjacent dorsal roots. We found that in the presence of bicuculline, DRR recorded in the L4 dorsal root evoked by L5 dorsal root stimulation was reduced. Simultaneously, the monosynaptic reflex (MR) in the L5 ventral root was not affected; nevertheless, a long-lasting after discharge appeared. The addition of 2-amino-5 phosphonovalric acid (AP5), an antagonist of NMDA receptors, abolished the MR without changing the after discharge. Action potentials persisted in dorsal roots even in low Ca2+ concentration. Conclusions: Thus, firing interneurons could send their axons by dorsal roots. Antidromic potentials may be characteristics of the neonatal mouse, probably disappearing in adulthood.
Defense in Hard Times: Budget Pressure, High Demand, and Defense Transformation in the Obama Administration

The Obama Administration’s unprecedented retention of Bush Secretary of Defense Robert Gates paved the way for dramatic cuts to defense programs in the first few months of the Administration. This paper analyzes the process of developing and presenting the revised defense budget for Fiscal Year 2010. Following the approach of Eugene Bardach, as elaborated by Michael Barzelay, it develops an extrapolation-oriented case study of this episode, identifying the process context factors and process design features that activated or impeded causal mechanisms influential in this case. Consistent with Bardach’s “craftsmanship” approach, the paper closes with reflections on lessons learned from the case for application elsewhere.
Modeling Hurricane Evacutaion Decisions with Ethnographic Methods

This paper directly models individual and household hurricane evacuation behavior using ethnographic decision tree analysis. This approach uses a set of iterative processes to inductively derive a general decision model from specific individual decision models. To elicit the model described here, below the authors and several graduate students interviewed Miami residents who had been in South Florida during both Hurricanes Andrew in 1992 and Erin in 1995. The resulting model of hurricane evacuation decision processes was then tested with interview data collected from a separate random sample of 954 South Florida residents drawn from areas that were evacuation zones and areas immediately adjacent to them at the time of Hurricane Andrew. The model captures the complexity and messiness of real-life decision-making by including criteria-showing how people are constrained by their perceptions of the hurricane, the safety features of their homes, the time they have available to prepare for the hurricane, their age, and the reactions of other family members who are also deciding whether or not to evacuate. By showing the richness of the decision process as well as its messiness, results taken from this model can better inform emergency managers who need to know how people will react to the approach of a hurricane.
Lagrangian Coherent Structures and Vortex Formation in High Spatiotemporal‐Resolution Satellite Winds of an Atmospheric Kármán Vortex Street

Recent advances in geostationary imaging have enabled the derivation of high spatiotemporal‐resolution cloud‐motion winds for the study of mesoscale unsteady flows. Due to the general absence of ground truth, the quality assessment of satellite winds is challenging. In the current limited practice, straightforward plausibility checks on the smoothness of the retrieved wind field or tests on aggregated trends such as the mean velocity components are applied for quality control. In this study, we demonstrate additional diagnostic tools based on feature extraction from the retrieved velocity field. Lagrangian Coherent Structures (LCS), such as vortices and transport barriers, guide and constrain the emergence of cloud patterns. Evaluating the alignment of the extracted LCS with the observed cloud patterns can potentially serve as a test of the retrieved wind field to adequately explain the time‐dependent dynamics. We discuss the suitability and expressiveness of direct, geometry‐based, texture‐based, and feature‐based flow visualization methods for the quality assessment of high spatiotemporal‐resolution winds through the real‐world example of an atmospheric Kármán vortex street and its laboratory archetype, the 2D cylinder flow.
Dual polarized open-ended waveguide using 7-layer PTFE board

We propose a wideband and dual polarized open-ended waveguide for planar array antennas. The proposal forms most of the antenna structures including waveguide and feeding networks in the dielectric substrates. This yields two advantages. First, it reduces the antenna dimensions because the waveguide is filled with dielectric; this yields 30% bandwidth and short element spacing without grating lobes. Second, it simplifies the machining process, especially for the case of large scale arrays consisting of several hundred elements. We design antenna elements and a four-element array, and then fabricate the four-element array using a 7-layer board of PTFE. Though the calculated and measured reflection characteristics diverge slightly, the radiation patterns well match.
TPV conversion of nuclear energy for space applications

This paper explores the possibility of achieving high conversion efficiencies in a closed loop TPV system by replacing the typical combustion thermal source with a nuclear thermal source such as a high temperature gas cooled reactor. Possible applications are nuclear electric propulsion, long‐term power for mission support systems, and terrestrial base nuclear power systems. The emitter portion of the system utilizes a novel low temperature processing technique, while the collector portion of the system utilizes a holographic concentrator/spectral splitter to reduce cell area and remove off‐band emissions.
ASSESSMENT OF DRINKING WATER QUALITY IN RURAL AREAS OF SONITPUR DISTRICT (ASSAM), INDIA.

The aim of this study is to assess the water quality of ground water in rural areas as the water is extensively used for several purposes of daily use including drinking one. Ground water was collected from rural areas (North-Eastern region) of Tezpur city of Assam (India). The above areas are situated nearby Defence Research Laboratory. The water samples were collected from different consumer ends viz. open wells, bore wells, tube wells etc. for the analysis of physicochemical parameters like pH, Dissolved Oxygen (DO), TDS, Turbidity, Conductivity, Resistivity, Salinity, Iron and Fluoride. pH, turbidity, bacteria and iron of few samples are found to have more than permissible limit (WHO/BIS/USEPA) with DO<4 ppm. Civil population use ground water for drinking purposes and they face health effect due to contaminants present in the water.
Selection of an Alternate Biocide for the ISS Internal Thermal Control System Coolant, Phase 2

The ISS (International Space Station) ITCS (Internal Thermal Control System) includes two internal coolant loops that utilize an aqueous based coolant for heat transfer. A silver salt biocide had previously been utilized as an additive in the coolant formulation to control the growth and proliferation of microorganisms within the coolant loops. Ground-based and in-flight testing demonstrated that the silver salt was rapidly depleted, and did not act as an effective long-term biocide. Efforts to select an optimal alternate biocide for the ITCS coolant application have been underway and are now in the final stages. An extensive evaluation of biocides was conducted to down-select to several candidates for test trials and was reported on previously. Criteria for that down-select included: the need for safe, non-intrusive implementation and operation in a functioning system; the ability to control existing planktonic and biofilm residing microorganisms; a negligible impact on system-wetted materials of construction; and a negligible reactivity with existing coolant additives. Candidate testing to provide data for the selection of an optimal alternate biocide is now in the final stages. That testing has included rapid biocide effectiveness screening using Biolog MT2 plates to determine minimum inhibitory concentration (amount that will inhibit visible growth of microorganisms), time kill studies to determine the exposure time required to completely eliminate organism growth, materials compatibility exposure evaluations, coolant compatibility studies, and bench-top simulated coolant testing. This paper reports the current status of the effort to select an alternate biocide for the ISS ITCS coolant. The results of various test results to select the optimal candidate are presented.
Pervasive Games: Theory and Design

Quickly emerging from the fast-paced growth of mobile communications and wireless technologies, pervasive games take gaming away from the computer screen and back to the three-dimensional world. Now games can be designed to be played in public spaces like shopping malls, conferences, museums and other non-traditional game venues. Game designers need to understand how to use the world as a gamespace-and both the challenges and advantages of doing so. This book shows how to change the face of play-who plays, when and where they play and what that play means to all involved. The authors explore aspects of pervasive games that concern game designers: what makes these games compelling, what makes them possible today and how they are made. For game researchers, it provides a solid theoretical, philosophical and aesthetic understanding of the genre. Pervasive Games covers everything from theory and design to history and marketing. designers, so that they can learn how to engage players' real-time experiences beyond the mobile phone or computer screen. -Thirteen case studies with illustrative and inspiring examples make the entire pervasive games design space tangible. -Provides practical design tips, potential pitfalls, design problems from real games, and inspiration from some of the most interesting pervasive game designers in the world, including Matt Adams, Frank Lantz, and others.
