Information is provided on the processes and procedures used by a number of states in using PCC pavement as aggregate in reconstructed concrete pavement. Since 1975 a number of state highway agencies have reconstructed concrete pavements using the old PCC as aggregate in the new pavement. This report of the Transportation Research Board describes the processes used on various projects in several states, giving details of construction procedures, as well as test results on various properties of the recycled aggregates and the resultant concrete.
A multilevel analysis of project lead the way implementation in Indiana

Sorge, Brandon H. Ph.D., Purdue University, December 2014. A Multilevel Analysis of Project Lead the Way Implementation in Indiana. Major Professor: Melissa Dark. Using data from the 2010 Indiana public high school graduating class (N=55612), this project employed a multi-level analysis to determine, what if any differences occurred in majoring in STEM and freshman to sophomore year persistence, between students attending a school that offers Project Lead the Way and students that don’t, while controlling for being a PLTW student. Additionally, this project explored the mitigating institutional factors that influenced a student majoring in STEM or persisting from their freshman to sophomore year in post-secondary education and if and how these factors varied depending upon if a student took PLTW courses, attended a PLTW school but did not take any PLTW courses, or attended a school that did not offer PLTW.
Performance of structurally integrated antennas subjected to dynamical loads

This paper proposes a coupling approach to investigate the effects of dynamic loads on the performance of structurally integrated antenna. In this method, the deformed displacement of radiating elements is determined by using the modal superposition principle of dynamic mechanic equation. Subsequently, the deformed displacement is coupled to the radiated field equation of the antenna array considering the effect of mutual coupling. Finally, an electromechanical coupling model is built by combining the equations from two different disciplines. An iterative solution method is presented to solve the coupling model. Some experimental devices are designed by utilizing a 2.5 GHz structurally integrated antenna, and the results confirm the effectiveness of the coupling model. The validated model is applied to investigate the influences of dynamic loads on the mechanical and electrical performance. The results show that the deformed displacement of radiating elements depends on the structural constraint forms and dynamic load values. Moreover, the greater the deformed displacement of the antenna array surface, the more serious the degradation of the electrical performance. The coupling model is particularly suited to the multidisciplinary analysis and design of structurally integrated antenna.
Forecasting Model for Mango (Mangifera indica) Malformation in New Delhi and Lucknow

Data related to intensity of mango malformation and weather variables at New Delhi and Lucknow were collected. They were analyzed for their relation and for developing and validation of MLR prediction models. The resultant correlation matrix found less than 0.1 was considered not having relation to malformation intensity with that particular weather variable and was excluded in further multiple linear regression analysis. Data from 1993 to 2000 was used for developing prediction models and are validated by using data from 2001 to 2006 for both FBD (flower bud differentiation) and flowering stages. The percent deviation was calculated which gave good forecasting of disease intensity for all selected malformation prone areas. For Delhi the wind speed, RH2, minimum and maximum temperatures were positively correlated with mango malformation and the MLR models under predicted the disease intensity for both FBD and flowering stages. Lucknow, at flowering stage maximum temperature and minimum temperature showed significant relation with the mango malformation and the MLR model at FBD stage showed a very good estimate whereas for flowering stage it gave reasonable estimate. The model under predicted the disease during FBD stage whereas it was over predicted at flowering stage.
Section, Member and System Level Analyses for Precast Concrete Hybrid Frames

Experimental studies have shown that precast concrete hybrid frames with dry jointed moment connections can provide adequate lateral force resistance for buildings located in high seismic zones. This framing concept, which has been approved for use by code officials, utilizes unbonded post-tensioning and mild steel reinforcement that is debonded over a short distance to establish a moment resisting connection between a precast beam and a precast column. As a result, the hybrid frames have the ability to dissipate energy and sustain minimal residual displacements when subjected to earthquake lateral forces. Due to the use of unbonded steel reinforcement, the hybrid connection concept introduces strain incompatibility between the reinforcement and the surrounding concrete, making the analysis and design of the connection difficult. Consequently, the available analysis and design methods for hybrid frame connections are based on many simplified assumptions. The analytical investigation presented in this report examines the monolithic beam analogy concept and establishes an improved set of expressions for estimating concrete and steel strains at the connection. The accuracy of the improved set of equations is verified using experimental data through section (or connection) and system level analyses. The improved analysis procedure is then demonstrated for a member level analysis and seismic analysis of a five-story precast hybrid building under different earthquake input motions. Using the analytical response of the five-story building, the following are examined: the benefits of using flexible floor links in hybrid frames, the ability of hybrid frames to satisfy limit states when subjected to different earthquake intensities, and suitable response modification (R-) factors for the force based design of hybrid frames.
Flight Demonstration of Integrated Airport Surface Movement Technologies

ABSTRACTThis document describes operations associated with a set of flight experiments anddemonstrations using a Boeing-757-200 research aircraft as part of low visibility landingand surface operations (LVLASO) research activities. To support this experiment, the B-757 performed flight and taxi operations at the Harts field-Atlanta International Airport(ATL) in Atlanta, GA. The test aircraft was equipped with experimental displays that weredesigned to provide flight crews with sufficient information to enable safe, expedientsurface operations in any weather condition down to a runway visual range (RVR) of 300feet. In addition to flight deck displays and supporting equipment onboard the B-757,there was also a ground-based component of the system that provided for ground controllerinputs and surveillance of airport surface movements.The integrated ground and airborne components resulted in a system that has the potentialto significantly improve the safety and efficiency of airport surface movements particularlyas weather conditions deteriorate. Several advanced technologies were employed to showthe validity of the operational concept at a major airport facility, to validate flight simulationfindings, and to assess each of the individual technologies' performance in an airportenvironment. Results show that while the lack of maturity of some of the technologies donot permit immediate implementation, the operational concept is valid and the performanceis more than adequate in many areas. Finally, over 100 visitors from the Federal AviationAdministration (FAA) and the aviation community attended the demonstration sessionstoward the end of the testing phase. Their impressions are also documented here.REFERENCEThis activity can be considered a follow-on to trials performed at the FAA Technical Centerin Atlantic City, NJ during the summer of 1995 on NASA's Boeing-737-100 aircraft [1]. This flight test activity builds on lessons-learned in 1995 as well as flight simulation studiesand a workshop [2] held in the interim.ACKNOWLEDGMENTSThe success of this project was the result of the efforts of a talented, dedicated team of over100 individuals from NASA, the FAA, and private industry. The authors would like tothank Mr. Vincent Capezzuto of the Federal Aviation Administration, Mr. Stefan Koczo ofRockwell International, Mr. Anthony Lobrutto of Cardion, Inc., Mr. James Savard ofJeppesen-Sanderson, Dr. James Rankin of St. Cloud State University, and Mr. IanMcWilliams of the Volpe National Transportation Systems Center. These individuals ledthe work being done outside NASA and were able to do so in exemplary fashion whilemeeting a rugged schedule and a challenging technical and operational milestone.
The influence of hull boundary layers on waterjet intake performance

The influence of hull boundary layers on typical waterjet propulsion system intakes used in the fast catamaran ferry industry has been experimentally and computationally studied. Particular attention was paid to the effect of boundary layer thickness on flow quality at the pump impeller face. A scale waterjet intake model mounted on the side wall of a wind tunnel enabled performance to be determined experimentally. Surface mini-tufts, ingestion streamtube determination, skin friction measurements and velocity and thermal anemometry traverses were used to detail the flow. The most significant observation was the presence of a separation zone on the intake roof. Two complete sets of results were obtained: one with the wind tunnel's naturally thin boundary layer and another with an artificially thickened boundary layer. The latter showed more extensive flow separation. Computational work was conducted using the commercial finite element package FIDAP. Grid independence required a surprisingly large number of nodes (approximately 300,000). However, good agreement with experimental results was obtained with about 120,000 nodes. Waterjet intakes installed on fast catamaran ferries ingest thick hull boundary layers (hull boundary layer thickness is comparable with the intake diameter). Both experimental and computational results show that a thick hull boundary layer adversely effects the performance of such intakes. Therefore, inclusion of thick hull boundary layers in the modelling/ designing of waterjet systems is essential for realistic performance predictions. The intake performance under manoeuvring conditions (zero vessel speed) was also studied both experimentally and computationally. It was found that cut-water flow separation choked the inlet and severely limited the available manoeuvring thrust. Computational results for an increased cut-water radius indicated that substantial improvement is possible with no detrimental effect on cruise performance.
Relationship Between Unsignalised Intersection Geometry and Accident Rates - A Literature Review

This paper discusses the results of a literature review of studies relating intersection geometry to accident rates. It also discusses a research project currently being undertaken at the Queensland University of Technology to determine the effect of unsignalised intersection geometry, traffic volumes and other parameters on the rates and various types of accidents occurring for Australian conditions. The literature review revealed that most studies have found traffic flow to be by far the most important independent variable, with geometric parameters having only a small effect. The majority of studies have identified that the minor road flow affects accident rates more than the major road flow. Several statistically significant geometric and other parameters have been found across the various studies. However, there is little consistency between the results of these studies. If a particular study identified an important parameter (other than traffic volume), then this parameter often was not considered by other studies, was not found to be important, or was found to have the opposite effect. The only results found consistent across two or more independent studies are that T-intersections are safer than cross-intersections, lit intersections are safer than unlit intersections, and larger stop signs on the minor legs result in a lower accident rate. This paper also discusses the proposed approach to be undertaken for the research project, given consideration of the results of the literature review.
FREE THE CHILDREN! DOWN WITH PLAYGROUNDS!

"Just put up the fence - the kids'll find something to do inside it. " This remark was made recently by a parent serving on a committee overseeing the design of a neighbourhood playground. The committee had asked a group of students in a senior design studio to come up with a decent playground. Working with the residents and drawing on recent environmental design research, the students coughed up five plans. At a neighbourhood meeting, the residents rejected them all. The reason? No fence. During the meeting the residents unanimously supported this fence, described enthusiastically as a ten foot-high chain link fence with barbed wire along its top. After heavy debate, they decided they could skip the barbed wire. When informed by the designers that, given the budget, they could have either the fence around or the play equipment within the playground, the residents were overwhelmingly for the fence. The students castigated these parents as Neanderthals. I disagree. As far as I can see, their attitudes toward playgrounds differ from those of others only in being less hypocritical. Armed with their mandate, the students retumed to their drawing boards to do fence details.
Biomimetic oscillating foil propulsion to enhance underwater vehicle agility and maneuverability

Abstract : Inspired by the swimming abilities of marine animals, this theses presents "Finnegan the RoboTurtle," an autonomous underwater vehicle (AUV) powered entirely by four flapping foils. Biomimetic actuation is shown to produce dramatic improvements in AUV maneuvering at cruising speeds, while simultaneously allowing for agility at low speeds. Using control algorithms linear in the modified Rodrigues parameters to support large angle maneuvers, the vehicle is successfully controlled in banded and twisting turns, exceeding the best reported AUV turning performance by more than a factor of two. Observations of "Myrtle," a 250kg Green sea turtle (Chelonia Mydas) at the New England Aquarium, are detailed: along with steady swimming, Myrtle is observed performing level turns and rapidly actuating pitch to control depth and speed. Limb kinematics for the level turning maneuver are replicated by Finnegan, and turning rates comparable to those of the turtle are achieved.
Taking Soil Science to Farmers’ Doorsteps through Community Watershed Management**

This lecture is dedicated to great soil scientist Dr. B.V. Mehta and the research is based on the work of a large number of research and development workers from different institutions, including policy makers and resource poor farmers. Soil Science is the backbone of sustainable management and development of natural resources and thus has to play an important role in meeting the emerging challenges. Scientists and policy makers in the tropical developing world have a major challenge on land as this region is hotspot of poverty, malnutrition, water scarcity, land degradation and desertification and most likely to bear the brunt of consequences of climate change due to global warming. However, ground reality reveals that despite availability of modern science, tools and scientific knowledge in the research institutes, the poor farmers are struggling to meet their daily needs and are suffering from poverty. Due to lack of opportunities for the Soil Scientists, the students in Soil Science are shying away from the discipline; and as a result the new strategic research in the areas of analytical technique development, application of research findings at the field level as well as policy formulation are suffering very badly. Soil Scientists need to take on the challenge and translate the present challenge into opportunities and contribute significantly to achieve the millennium development goals of sustainable development, reducing poverty, improving access and availability of drinking water and building global partnerships. To achieve this goal, community watersheds framework provide opportunities as well as necessary impetus to bring back the soil science at the center stage to help the humankind.
PSYCHOLOGICAL FEATURES OF EMOTIONAL INTELLIGENCE

Статтю присвячено висвітленню психологічних особливостей емоційного інтелекту, аналізу концепцій та моделей емоційного інтелекту у зарубіжній та вітчизняній психології, зокрема розгляду його змісту та структури, вивченню внутрішньо-особистісного та міжособистісного аспектів емоційного інтелекту. На сьогоднішній день зростає кількість наукових досліджень, спрямованих на вивчення емоційного інтелекту серед зарубіжних та вітчизняних вчених, які досліджують різні психологічні особливості прояву емоційного інтелекту. Дж. Майер, П. Саловей розглядають емоційний інтелект як групу ментальних здібностей, які сприяють усвідомленню і розумінню власних емоцій та емоцій оточуючих. У наукових працях представлені наступні моделі емоційного інтелекту: модель здібностей, в якій подана ідея про перетин емоцій та мислення (Дж. Майер, П. Саловей); змішана модель – поєднання інтелектуальних, емоційних та особистісних властивостей людини (Р. Бар-Он та Д. Гоулман). Іншого погляду дотримуються дослідники К. В. Петрідес та Е. Фернхем, які розглядають емоційний інтелект як рису особистості та як здібність до обробки емоційної інформації, спираючись на конструкт «емоційної самоефективності». І. М. Андрєєва виділяє інтегративну модель емоційного інтелекту та розглядає інтегральний емоційний інтелект як когнітивно-особистісне утворення, як сукупність розумових здібностей до розуміння емоцій та управління ними, компетенцій, пов’язаних з обробкою та перетворенням емоційної інформації, а також комунікативних, емоційний, інтелектуальних та регулятивних особистісних властивостей, які сприяють адаптації індивіда. У дослідженні Е. Л. Носенко та Н. В. Ковриги емоційний інтелект розглядається як аспект виявлення внутрішнього світу особистості, що відображає міру розумності ставлення людини до світу, до інших та до себе як суб’єкта життєдіяльності. Йому притаманні внутрішні (диспозиційні) та зовнішні (ті, що виявляються в ознаках перебігу емоційного процесу) компоненти, які зумовлюють стресозахисну та адаптивну функції цієї інтегральної особистісної властивості. Дослідники запропонували ієрархічну структуру рівнів сформованості емоційного інтелекту. Внутрішньоособистісний та міжособистісний аспекти емоційного інтелекту виділяють як зарубіжні, так і вітчизняні дослідники, серед них Г. Гарднер, Дж. Майер, П. Саловей, Д. В. Люсін, Е. Л. Носенко, Н. В. Коврига, М. А. Манойлова, І. М. Андрєєва та ін. На думку Г. Гарднера, внутрішньоособистісний емоційний інтелект – це вміння людини розуміти власні емоції та почуття, їх витоки і регулювати на цій основі власну поведінку, а міжособистісний емоційний інтелект – це вміння людини взаємодіяти з іншими людьми. Отже, емоційний інтелект – це інтегральна властивість особистості, яка сприяє її гармонійному розвитку та покращенню міжособистісної взаємодії.
What do cars do when they are parked? Material objects and infrastructuring in social practices

ABSTRACT The paper problematises current conceptualisations of objects in social practices by investigating car parking, using original research material. Motionless cars are not only ‘leftovers’ of driving – they actively perform parking while waiting for their users to start driving again. They infrastructure everyday im|mobility and play a part in shaping urban environments. Two modalities of social practice are discerned and described to account for these performative capacities of objects. By describing different ways in which cars are taken care of and take part in parking in the material setting of a street, the article argues for more attention to non-human objects involved in social practices, particularly in the context of their infrastructuring capacities. The article contributes to the current developments in theories of social practices, discourses on social materiality and infrastructuring and complements existing understandings of automobility.
Experience of Emergency Medical Services Response to Arasbaran Earthquakes in 2012:  A Qualitative Study

Background One of the most important concerns in responding to disasters is providing Basic Life Support (BLS) services to injuries. Considering the key role of Emergency Medical Services (EMS) in providing BLS, the purpose of this study is to investigate the experience of provincial EMS's response to the Arasbaran twin earthquakes and its challenges in 2012 in Iran.Methods In this qualitative content analysis, data were collected through Focus Group Discussions (FGD) and semi-structured in-depth interviews with purposefully-selected EMS paramedics and officers in East Azerbaijan Province, Iran. To form the main categories, the interviews were encoded in three stages and the similar codes were placed under the same subcategories and merged.Results A total of 26 EMS paramedics and officers participated in the study. The codes extracted from their interviews were divided into ten categories, including; the lack of preparedness and coordination, dead bodies' management challenges, responders’ psychosocial support, deficiencies in supplies and ambulances, difficulty of access to rural areas, volunteer management, non-documentation of the experiences, communication challenges, recalling and deploying of EMS responders.Conclusion According to the findings, EMS timely response and paramedic's sense of responsibility for providing services were a positive point about the EMS operations. The weaknesses of the system should therefore be addressed through transferring of experiences and by planning and arranging training courses.
