Résumé :

The aim of the study is to estimate the effect of the Russian academic excellence project (Project 5-100) on the publication activity of the University of Tyumen, measured by the number of articles published in journals indexed in the Web of Science database. The hypothesis of the research is that there is a positive causal relationship between the number of published articles and the University’s participation in Project 5-100. This impact was estimated empirically for the University of Tyumen while the other university participants (31 universities) were taken as a control group. Counterfactual scenarios are used to find the number of articles that the university employees would have published in the absence of Project 5-100. Thus, it is shown that, despite the failure to meet the goal of entering the top 200 of world universities in the ranking for ecology and agricultural biology, the University of Tyumen benefited from its participation in Project 5-100: its number of publications, especially in journals of the first and second quartile, has been growing faster than in the control group of universities.

Résumé :

The project called “5-100” has been established in Russia in 2013 for the period of time from 2013 up to 2020. It was supposed that this project would be resulted in entry of 5 Russian universities into 100 highest positions of the world university ratings. 21 Russian universities were chosen as the participants of the project. To achieve the purpose of the project, every chosen university received considerable financial support from the Russian federal government. Among others, two universities from the city of Tomsk – Tomsk State University (TSU) and Tomsk Polytechnic University (TPU) were the participants of this project. In spite of the identical starting points, the universities have demonstrated substantially different results by the end of the project implementation. In this article, we attempted to explain the difference of the results through difference of the corporate cultures of both universities. The corporate culture study has been done using OCAI method. The study showed that TGU’s corporate culture looks like more competitive than TPU’s one. It was proved by the comparison of the TPU and TGU cultures with cultures of the foreign universities.

Résumé :

The implementation of the 5-100 Project in Russian universities, aimed at improving their competitiveness through adaptation to world standards and inclusion in the international educational environment has produced some quantitative and qualitative results. Despite the undoubted achievements of the universities participating in the Project, the mechanisms of its implementation have revealed some problematic areas that in the end can primarily affect the young generations of scholars. Therefore, assessing the perception of the 5-100 Project by scholars of different ages is important. The purpose of this article is to analyze, through the lens of a generational approach, the risks associated with the two aspects of universities’ activities. First, the principles of funding under the 5-100 Project and second, the approaches applied for assessment of academic performance. The analysis is based on the results of semi-structured interviews with scientific and pedagogical staff at five universities that participated in the 5-100 Project (108 respondents). We analyzed the answers of respondents in three age groups: young scientists, middle-aged and older scholars. The study showed that there are areas where representatives of all generations are unanimous and areas where the young academics have perceptions different from other generations. There is unanimity in the attitudes to principles of financing practiced in the universities. The younger generation turned to be the most sensitive to insufficient spending on research equipment. In terms of performance evaluation indicators, the younger generation demonstrated the greatest adaptability to the system of formal quantitative assessment, while noting its dysfunctional effects. They have also revealed that it is easier for them to change jobs than for other generations of scholars.

Résumé :

Il panorama dell'istruzione superiore in Russia è cambiato in modo significativo nel corso degli anni 2010 grazie all'attuazione dell'iniziativa di eccellenza Progetto 5-100. L'iniziativa è stata lanciata per aumentare la competitività globale di un gruppo di università russe. In precedenza, alcuni studi avevano riportato una crescita degli indicatori associati alla dimensione internazionale per i partecipanti al Progetto 5-100, mentre in pochi avevano considerato le percezioni del personale universitario e mostrato come le università hanno vissuto il processo di rapida internazionalizzazione. La tesi indaga l'impatto del Progetto 5-100 sull'evoluzione del posizionamento internazionale dell'Università Federale degli Urali e di tre delle sue unità accademiche. Queste ultime sono state scelte sulla base della loro performance durante la prima fase del Progetto 5- 100. Il presente lavoro evidenzia anche come l'internazionalizzazione sia stata riposizionata durante e in conclusione dell'iniziativa di eccellenza nel 2020 per quanto riguarda i criteri, le strategie di ricerca e didattica e i servizi. La tesi costruisce tre casi studio corrispondenti a tre rispettive unità accademiche sulla base dell'analisi tematica di interviste a 53 partecipanti allo studio e dell'analisi documentale dei piani strategici. La ricerca è supportata dal Rationales Prioritization Exercise (Lewis, 2007; di seguito RPE) e dall'analisi del contesto. Lo studio adotta la teoria del posizionamento (van Langenhove & Harré, 1999) come prospettiva teorica, considerando i documenti strategici e le interviste con i partecipanti allo studio come cornice contestuale. La definizione di internazionalizzazione di de Wit et al. (2015) è stata utilizzata come quadro concettuale: l'internazionalizzazione è intesa come un processo intenzionale che migliora la qualità dell'istruzione e della ricerca e coinvolge tutti gli studenti e il personale al fine di contribuire alla società. Le conclusioni dimostrano che le tre unità accademiche hanno scelto strategie diverse di internazionalizzazione all'interno dello stesso contesto dato dal Progetto 5-100, ma il loro posizionamento internazionale si è evoluto in modo simile proprio grazie all'iniziativa di eccellenza. La ricerca illustra che l'Università Federale degli Urali ha compiuto un cambiamento significativo verso la comprensione dell'internazionalizzazione così come definita da de Wit et al. (2015) e l'ha riposizionata a livello universitario. Infatti, l'internazionalizzazione nell'Università Federale degli Urali è passata dall’essere un insieme di attività specifiche a un processo intenzionale e parte integrante della vita accademica dell'università. La tesi dimostra inoltre che le unità accademiche hanno riposizionato l'internazionalizzazione in un modo da corrispondere alle loro caratteristiche uniche e strategie adottate.
The landscape of higher education in Russia significantly changed during 2010s due to the implementation of the excellence initiative Project 5-100. The initiative was launched in order to increase the global competitiveness of a group of Russian universities. Previous research had reported a growth in indicators associated with the international dimension for the participants of Project 5-100, while little research had considered the perceptions of university staff and shown how universities experienced the process of rapid internationalization. The thesis investigates the impact of Project 5-100 on the evolution of the international positioning of Ural Federal University and three of its academic units. These were chosen on the basis of their performance during the first half of Project 5-100. The present work also uncovers how internationalization was repositioned during the excellence initiative with regard to rationales, research and educational strategies, and services by the end of the excellent initiative in 2020. The thesis constructs three case studies of respective academic units based on the thematic analysis of interviews with 53 study participants and the document analysis of Strategic Plans. The research is supported by the Rationales Prioritization Exercise (Lewis, 2007; hereon RPE) and analysis of the context. The study adopts positioning theory (van Langenhove & Harré, 1999) as a theoretical lens where strategic documents and interviews with the study participants are considered as discourse. The definition of internationalization by de Wit et al. (2015) is used as a conceptual framework, where internationalization is understood as an intentional process that enhances the quality of education and research and involves all students and staff in order to contribute to society. The conclusions demonstrate that three academic units have chosen different strategies of internationalization within the same given context of Project 5-100, but their international positioning evolved in a similar way due to the timeframe of the excellence initiative. The research illustrates that Ural Federal University has made a significant shift towards understanding internationalization as defined by de Wit et al. (2015) and it has repositioned it at university level. Indeed, internationalization in Ural Federal University went from a set of specific activities to an intentional process and an integral part of the academic life of the university. The research also shows that the academic units repositioned internationalization in a way which matched their unique features and chosen strategies.

Résumé :

In the framework of the Terrafirma project, Persistent Scatterers Interferometry (PSI) has be used for mapping land subsidence at basin scale in Gioia Tauro plain (Italy). The investigated area is built over unconsolidated fine-grained sediments, where the increasing groundwater demands for irrigation have caused the natural sediment consolidation to progressively accelerate. Both historical (1992-2001; ERS1/2 images) and recent (2002-2006; ENVISAT images) scenarios are analyzed to solve the spatial variability and temporal evolution of ground displacements affecting the plain. The results show deformation rates as high as 10-12 mm/yr in 1992-2007, with highest velocities occurred between 1992 and 2000 within the central part of the basin, in the area of Rizziconi (5 km ESE of Gioia Tauro). The outcomes of this PSI study could support the future improvement of groundwater management and the implementation of best strategies for land use planning and sustainable use of groundwater resources.

Résumé :

Abstract This book presents some of the improved agricultural technologies that were validated by the Africa RISING Project in East and Southern Africa (ESA), focusing on smallholder farmers in Malawi, Tanzania, and Zambia, and working in partnership with development (scaling) institutions. It consists of 11 chapters. Chapter 1 shows how gender concerns must be woven into all sustainable intensification (SI) interventions to produce equitable outcomes. It describes activities to enhance women's participation, measure the benefits, and transform gender relations. Chapter 2 describes the performance of new cereal and legume crop varieties introduced by Africa RISING into agroecosystems in which they had not been tested before. Chapter 3 presents technologies to diversify the common maize-dominated cropping systems and address human nutrition, improve soil organic matter, and maximize the benefits of applying fertilizer. Chapter 4 presents technologies for replacing the nutrients lost from cropped fields with external fertilizer sources in a manner that minimizes the consequences of too little or too much application. Chapter 5 is about soil conservation. Chapter 6 presents conservation agriculture, which can help smallholder farmers build better resilience to the consequences of climate change and variable weather. Improved technologies for drying, shelling, and hermetic storage of grain are presented in Chapter 7. Chapter 8 provides information to help farmers use outputs from crop production systems to formulate supplementary feed. Chapter 9 follows with technologies that allow well-planned nutrition-specific interventions (recipes) to utilize various livestock and crop products to enhance family nutrition, with specific attention paid to diets for children. Chapter 10 presents examples from the preceding chapters to illustrate the potential impacts of interconnected technologies. Lastly, Chapter 11 presents experiences and lessons learned from using these approaches to transfer and scale the technologies.

Résumé :

AbstractThis paper describes the outline of the video tutorial prepared for vegetation workers and relevant officers in Bhutan to learn how vegetation works are to be done in remote areas. The Japan International Cooperation Agency (JICA for short) took a project on cutting unstable slopes in Gangthangkha, Wangdue, Bhutan, so that they should be gentler than 45° to improve slope stability with vegetation works. Particularly stabilizing slopes along Prime National Highway No. 1 (PNH-1 for short) was the overriding priority because slope failures along this highway have reportedly occurred in rainy seasons. Before vegetation works were carried out on the studied slope of the project, the authors conducted germination tests to choose seeds and methods suitable for the vegetation works. They chose Paspalum Atratum, Ruzi grass, and GM mixed (Grass Mixture seed formulating of Cock’s foot 70% and Italian Ryegrass 30% of 100 kg) based on their test results. The soil thickness associated with sowing was set at 5 cm. The authors tried the following types of vegetation methods on the studied site. Type A is arranging on the slope stripes of soil mixed with seeds and fertilizer, Type B is spreading out a five cm-thick seeds-mixed soil layer over the slope, and Type C is transplanting germination beds. In conclusion, Type C is the best in terms of its performance because the whole slope is quickly covered with already grown plants. In Type B, it is not until grass covers the entire slope that the slope is finally stabilized. Type A is good for seeds-mixed soil stripes, but it takes time for the grass to spread gradually over the whole slope.

Résumé :

The ATTAP aims at proving the performance and life of structural ceramic components in the hot gas path of an automotive gas turbine engine. This Department of Energy (DOE)-sponsored, NASA-managed program is being addressed by a General Motors (GM) team drawing expertise from the Advanced Engineering Staff (AES) and from Allison. The program includes design, process development and fabrication, rig and engine testing, and iterative development of selected key ceramic components for the AGT-5 engine. A reference powertrain design (RPD) based on this engine predicts acceleration, driveability, and fuel economy characteristics exceeding those of both current engines and the DOE goals. A low-apsect-ratio ceramic turbine rotor design has been successfully engine-demonstrated at 2200°F and 100% speed, including survival of impact and other hostile flow path conditions. Turbine flow path components have been designed for the 2500°F cycle, using improved monolithic ceramics targeted for Year 2 fabrication. Major development/fabrication efforts have been subcontracted at Carborundum, GTE Labs, Corning Glass, Garrett Ceramic Components, and Manville. Feasibility studies were initiated with Ceramics Process Systems and Drexel University.

Résumé :

Abstract Doosan is developing a 5 MW 100% hydrogen gas turbine combustor based on the existing NG (natural gas) firing combustor through a national project. This engine consists of 8 (eight) cans of the combustor and our plan is to develop a hydrogen burner to replace the existing NG burner, if possible, without any change of other combustor components such as liner & transition piece, etc. We developed various concept nozzles for 100% hydrogen combustion without flash back during the operating condition and low NOx emission using dry low NOx premixed combustion methods. Among the various concept nozzles several candidates conducted experiment test in ambient pressure condition which they showed low NOx emission and larger operating conditions through lean blow off and flame holding flash back test. The best nozzle will be selected and tested at ambient & high pressure can test for evaluating 100% hydrogen combustor development targets.

Résumé :

Both single-agency and multi-agency efforts are currently underway to put a Doppler lidar wind sounder into space within the next decade. Justification for this ambitious project rests mainly in the universally recognized need to provide direct measurements of the winds as input to both climate studies and forecast models. Expectations of success are based heavily upon ground-based observations as well as a few airborne observations. While the space-based observations will be taken at 5-10 Hz providing samples with a spatial separation of 50 to 70 kilometers within the earth's atmosphere, both the ground-based and airborne observations have been acquired primarily at 20 to 100 hertz providing a shot density of many samples per square meter resolution. Furthermore, many of the wind velocity estimates derived from these ground-based and airborne instruments have been acquired by using a poly-pulse pair technique involving 20 to sometimes 100 pulses. Currently there is very little in the way of data that is acquired in a single shot mode and processed to achieve resolution, both in space and time, that will approximate that which is achievable with a space-based system.

Résumé :

The direct steam generation (DSG) in parabolic trough collectors is a promising option to improve the mature parabolic trough solar thermal power plant technology of the Solar Energy Generating Systems (SEGS) in California. According to previous studies [1–3], the cost reduction of the DSG process compared to the SEGS technology is expected to be 8 to 25%. All these studies were more or less preliminary since they lacked detailed information on the design of collector fields, absorber tubes required for steam temperatures higher than 400°C and power blocks adapted to the specific needs of the direct steam generation. To bridge this gap, a detailed system analysis was performed within the German R&D project DIVA. Power blocks and collector fields were designed for four different capacities (5, 10, 50 and 100 MWel) and different live steam parameters. The live steam temperature was varied between saturation temperature and 500°C, and live steam pressures of 40, 64 and 100 bar were investigated. To assess the different cases, detailed yield analyses of the overall system were performed using hourly data for the direct normal irradiation and the ambient temperature for typical years. Based on these results the levelized costs of electricity were determined for all cases and compared to a reference system using synthetic oil as heat transfer fluid (HTF). This paper focuses on two main project findings. First, the 50 MWel DSG system parameter comparisons are presented. Second, the detailed comparison between a DSG and a SEGS-like 100 MWel system is given. The main result of the investigation is that the benefit of the DSG process depends on the project site and can reach an 11% reduction of the levelized electricity cost (LEC).

Résumé :

Abstract Starting in 2002, Belgoprocess will proceed with the treatment and conditioning of some 200 m3 of widely varying high- and medium-level wastes from earlier research and development work, to meet standard acceptance criteria for later disposal. The gross volume of primary and secondary packages amounts to 2,600 m3. The wastes have been kept in decay storage for up to 30 years. The project was started in 1998. Operation of the various processing facilities will take 7–8 years. The overall volume of conditioned waste will be of the order of 800 m3. All conditioned waste will be stored in appropriate storage facilities onsite. At present (August, 2000), the construction of a new processing facility is in progress and the call for venders for the equipment has been sent out. Several cells of the Pamela vitrification facility onsite will be adapted for the treatment of high-level and highly α-contaminated wastes; low-level β/γ wastes will be treated in the existing facility for supercompaction and conditioning by embedding into cement (CILVA). The bulk of these wastes, of which 95% are solids, the remainder consisting of mainly solidified liquids, have been produced between 1967 and 1988. They originate from various research programmes and reactor operation at the Belgian nuclear energy research centre SCK•CEN, isotope production, decontamination and dismantling operations. The wastes are stored in 4800 primary packages, of which 700 contain 120 g (5.1012 Bq) radium. Half the radium inventory is present in 25 containers. The presence of radium in waste packages, resulting in the emission of radon gas, requires particular measurements and the welding of packages for storage, in order to allow a correct interpretation of alpha measurements onsite. The total activity at the moment of production amounted to 18,811 TBq β/γ and 34.4 TBq α, with individual packages emitting up to 555 TBq β/γ and 2.2 TBq α. According to calculations, the β/γ activity has decreased to some 2,000 TBq, with individual packages up to 112 TBq. The extreme diversity of the wastes is not only expressed in their radiological characteristics, but also in their chemical composition, physical state, the nature and condition of the packages. Radioactivity ranges between 0.01 mCi to 1,000 Ci per package. Some packages contain resins, Na, NaK and Al containing wastes, poison rods, residues of fuel elements. Although most of the liquid wastes are solidified, a small fraction — both aqueous and organic — still remains liquid. Primary packages may be plastic bags, metal boxes, wire gauze, La Calène boxes; secondary packages may be steel drums and concrete containers. Solid wastes may be sources, counters, control and poison rods, nuclear fuel residues, filters, synthetic materials, metals, resins, granulates, rock, sludges, cables, glass … Some 1000 primary packages are stored in a dry storage vault comprising 20 concrete cells, while 3800 primary packages are stored in some 2,000 concrete containers, on a concrete floor, surrounded by an earth bank to the height of the waste stacking and covered by a metal construction. At present, the annual production of similar wastes amounts to 2 m3 divided over some 30 containers. Generally, the primary waste packages will be loaded in 80 l drums (an average of 2 packages per drum), and compacted in a 150 t hydraulic press. The pellets will be collected in 100 l drums (an average of 3 pellets per drum). Low-level β/γ waste is transferred to the CILVA facility for further treatment, while the other 100 l drums are filled up with sand and, in the case of radium-contaminated wastes, tight-welded. Subsequently, the 100 l drums are loaded into 400 l drums and embedded into cement. Certain packages, for example solidified radium-contaminated liquids in welded metal containers, are conditioned as such in overpacks. Specific procedures will be established for the various non-standard wastes, such as sources, control and poison rods, resins and filters, fuel residues. The new processing facility is being built partly over the dry storage vaults, in the immediate vicinity of the already covered storage area. It comprises 1) feeder locks for the introduction of the various waste packages; 2) a dispatching cell in which the primary packages are loaded into 80 l drums; 3) the processing cell in which the 80 l drums are compacted and the pellets loaded into 100 l drums; and either sent to the CILVA facility (low-level β/γ wastes), or the Pamela facility (highly active and/or heavily α-contaminated), or further treated in 4) the transport area, in which radium and medium-level waste containing drums are conditioned into cement; 5) the measurement and characterisation cell, in which the conditioned waste is characterized by gamma spectrometry, and checked for compliance with maximum allowed surface contamination and dose rate in view of interim storage in the appropriate facilities onsite. Ideally, gamma spectrometry measurements are carried out on the primary packages, but due to the extreme diversity of these packages, ranging from plastic bags containing cardboard to highly active steel valves, preference was given to measurements on the conditioned wastes, or at least on already pre-compacted wastes in the case of treatment in the 2,000 t press of the CILVA facility. Thus tremendous problems of calibration can be largely avoided. All operations are remotely controlled. Transfers between buildings are carried out within appropriately shielded containers and secondary wastes will be treated in existing facilities onsite.

Résumé :

This paper describes the system setup and presents results from the ongoing BioSOFC project. The project aims at demonstrating integration of atmospheric biomass steam gasification, high temperature gas cleaning and Solid Oxide Fuel Cells (SOFCs). This is done by taking a slipstream from a steam gasification reactor (the Fast Internally Circulating Fluidised Bed (FICFB) gasifier at Biomasse Kraftwerk Gu¨ssing in Gu¨ssing, Austria) as fuel feed for a 5 kWel Solid Oxide Fuel Cell (SOFC) stack. The system also includes a novel high temperature particle filter (the Panel Bed Filter (PBF)) and a high temperature H2S removal unit. The biomass gasifier, using wood chips as fuel, has a dry producer gas consisting of H2 (up to 45 vol%), CO (up to 30 vol%), CO2 (up to 20 vol%), CH4 (8–12 vol%) and N2 (1–2 vol%). This gas composition makes the producer gas highly suitable as fuel for SOFCs. However, the gas has a relatively high particle loading (up to 60 g/Nm3) and a tar content of up to 2 g/Nm3. In addition, it has been reported that the dry producer gas contains 100–200 ppmv H2S and 500–1000 ppmv NH3. Due to otherwise expected fuel cell performance degradation, the particles have to be removed before entering the SOFC stack. In addition, the sulphur (mainly H2S) concentration must be reduced to minimize the performance degradation in the SOFC. The slipstream is taken from the top of the gasifier freeboard, and is then cooled from about 900°C to 550°C before entering the PBF where the particles are removed. The H2S concentration is reduced in a separate fixed-bed reactor with a Zink-oxide based sorbent. The pressure in the producer gas is increased from the somewhat below atmospheric pressure in the filter to the atmospheric pressure required by the SOFC stack. This pressure increase is achieved by means of two high temperature fans operated at about 525°C. The producer gas is then heated again to up to 900°C before entering the fuel cell stack. This paper presents results from component tests carried out at the Norwegian University of Science and Technology (NTNU) as well as results from the field tests of the system in Gu¨ssing. This ongoing project is scheduled to continue until December 2007. The BioSOFC project is carried out in cooperation with TU-Vienna and Austrian and Norwegian technology companies. The project is funded by the Research Council of Norway and six Norwegian companies.

Résumé :

A power unit constituted by a reformer, a H2 purification section and a fuel cell is being tested c/o the Dept. of Physical Chemistry and Electrochemistry of Universita` degli Studi di Milano, on the basis of a collaboration with Helbio S.A. Hydrogen and Energy Production Systems (supplier of the unit) and some sponsors (Linea Energia S.p.A., Parco Tecnologico Padano and Provincia di Lodi). The system size allows to cogenerate 5 kWe (a.c.) + 5 kWt (hot water at 65°C) as peak output. Bioethanol, obtainable by different non-food competitive biomass is transformed into syngas by a prereforming and a reforming stage and the reformate is purified from CO to a concentration below 20 ppmv, suitable to feed the proton exchange membrane fuel cells (PEMFC) stack integrated in the fuel processor. This result is achieved by feeding the reformate to two water gas shift reactors, connected in series and operating at high and low temperature, respectively. CO concentration in the outcoming gas is ca. 0.7 vol% and the final CO removal to meet the specifications is accomplished by two methanation stages in series. The second methanation step acts as a guard since ca. 15 ppmv of CO are obtained even after the first reactor. The purified H2 is suitable for feeding a 5 kWe PEMFC stack, which should have an expected overall efficiency higher than 80% (including thermal output). The main goal of the present project is to check system performance under different operating conditions, to verify the effectiveness of the proposed technology and to suggest adequate improvements. In particular, the system will be tested under different load, to check for the readyness of response. Another point will be the effect of bioethanol origin, purity and concentration, so to open the way to separation processes different from distillation. Due to the demonstrative character of the project the main part of the experimentation focuses on the accumulation of a suitable amount of hours-on-stream to validate the system feasibility. A parallel investigation is active on the development of alternative nanostructured catalysts for the present application. In particular, Ni, Co and Cu-based catalysts, supported over La2O3, TiO2 and SiO2 were tested at 500, 625 and 750°C. At the moment no perfect candidate has been found to operate the steam reforming at the lowest temperature, due to unsatisfactory material balances and by-products formation at 500°C with most catalysts. Good H2 productivity, with 100% C balance has been achieved at higher temperature (≥ 625°C).

Résumé :

The ESA ESEO Mission [1] included an amateur radio payload [2]. The results of which included the development of radio technologies that utilised final year student projects over a 5 year period. Many lessons regarding compliance and process enabled a new payload to follow: the Student Ranging Transponder Radio for X-band and L-band (or STAR-XL). The STAR-XL design leverages key aspects of the ESEO payload design for a generic CubeSat platform; including TT&C voltage and current sense circuitry, receiver circuitry, and flight software. But instead of a maximum 4800 bps telemetry and transponder system - the STAR- XL targets a 100 kHz bandwidth system that will allow faster downlink rates that are forward error correction, link margin and modulation order dependent. With 100 kHz bandwidth, the linear receiver is designed to also operate as a transponder - enabling ranging and navigation applications such as orbit determination and further experiments from amateur radio groundstations. This paper details the recent student project efforts in three key areas: a new STM32-based on-board computer, an X-band up-converter board and dual X/L band patch (as shown in Fig. 1). The new OBC includes an IQ modulator for transmitting complex waveforms and an optimised flight software suite that takes advantage of dual DMA hardware on-chip to reduce overheads. The X-band upconverter board required the development of new safety interlock and RF chain circuitry on a Rogers (RO4350B) PCB material. A new dual X/L-band patch antenna and filter circuit is also built and measured. Each of these projects has led to new lessons and increased the real-world case studies used to teach spacecraft avionics.

Résumé :

<p>The cement concrete industries globally produced about 4.2 billion tons (required processing energy 1,400kWh/ton) and produce 30 billion tons concrete and contribute about 7%global warming effects. Global rapid urbanization, energy demand in buildings will increase 50%, while existing global building floor area 220 billion m2 is expected to double by 2050, driving energy demand and related GHG emissions for construction. Thus, the shortcoming of innovative and sustainable cement concrete to bring together the building and construction industry to facilitate the global transition towards for low-emission, energy-efficient buildings to achieving the common objective of limiting global warming to well-below 2 Celsius (2°C). The objective in this study is to use the biomass and industrial waste to produce the Sustainable Ultra High Performance Cementitious (SUHPC) for Carbon Neutral Cement Concrete (CNCC). SUHPC was produced by biohybrid- mechano-chemical activation method. SUHPC performance was evaluated in OPC mortar by replace the OPC from dosage 5% to 100% Mortar prism strength with SUHPC at low dosage series increased the early strength but at high dosage series enhanced the early and ultimate strength of OPC. The produced SUHPC concrete quality strength is performed at high performance concrete (HPC) upto ultra high performance concrete (UHPC) level. The innovative SUHPC has proven here to be useful sustainable technology, increased productivity, durability and social economy benefits for Malaysian and abroad cement concrete plants for some rapid urbanization mega infrastructure projects such as Mega Railway Sleeper KV-Double Track MRT Project, Mega Tunnelling Pahang Water Transfer Projects (PWTP), Mass Rapid Transit (MRT) Project, Sarawak Hydropower Murum Dam and general construction projects. Embodied energy and CO2 emission reduced > 85% and reduced non-renewable materials approaching carbon neutral cement concrete. SUHPC is suitable for rapid urbanization and carbon neutral mega construction projects to provide the innovative sustainable construction materials development and future resilient construction.</p>

Résumé :

The Everglades National Park and Big Cypress National Preserve vegetation mapping project is part of the Comprehensive Everglades Restoration Plan (CERP). It is a cooperative effort between the South Florida Water Management District (SFWMD), the United States Army Corps of Engineers (USACE), and the National Park Service’s (NPS) Vegetation Mapping Inventory Program (VMI). The goal of this project is to produce a spatially and thematically accurate vegetation map of Everglades National Park and Big Cypress National Preserve prior to the completion of restoration efforts associated with CERP. This spatial product will serve as a record of baseline vegetation conditions for the purpose of: (1) documenting changes to the spatial extent, pattern, and proportion of plant communities within these two federally-managed units as they respond to hydrologic modifications resulting from the implementation of the CERP; and (2) providing vegetation and land-cover information to NPS park managers and scientists for use in park management, resource management, research, and monitoring. This mapping project covers an area of approximately 7,400 square kilometers (1.84 million acres [ac]) and consists of seven mapping regions: four regions in Everglades National Park, Regions 1–4, and three in Big Cypress National Preserve, Regions 5–7. The report focuses on the mapping effort associated with the Northwest Coastal Everglades (NWCE), Region 4 , in Everglades National Park. The NWCE encompasses a total area of 1,278 square kilometers (493.7 square miles [sq mi], or 315,955 ac) and is geographically located to the south of Big Cypress National Preserve, west of Shark River Slough (Region 1), and north of the Southwest Coastal Everglades (Region 3). Photo-interpretation was performed by superimposing a 50 × 50-meter (164 × 164-feet [ft] or 0.25 hectare [0.61 ac]) grid cell vector matrix over stereoscopic, 30 centimeters (11.8 inches) spatial resolution, color-infrared aerial imagery on a digital photogrammetric workstation. Photo-interpreters identified the dominant community in each cell by applying majority-rule algorithms, recognizing community-specific spectral signatures, and referencing an extensive ground-truth database. The dominant vegetation community within each grid cell was classified using a hierarchical classification system developed specifically for this project. Additionally, photo-interpreters categorized the absolute cover of cattail (Typha sp.) and any invasive species detected as either: Sparse (10–49%), Dominant (50–89%), or Monotypic (90–100%). A total of 178 thematic classes were used to map the NWCE. The most common vegetation classes are Mixed Mangrove Forest-Mixed and Transitional Bayhead Shrubland. These two communities accounted for about 10%, each, of the mapping area. Other notable classes include Short Sawgrass Marsh-Dense (8.1% of the map area), Mixed Graminoid Freshwater Marsh (4.7% of the map area), and Black Mangrove Forest (4.5% of the map area). The NWCE vegetation map has a thematic class accuracy of 88.4% with a lower 90th Percentile Confidence Interval of 84.5%.

Résumé :

Wildlife-vehicle collisions (WVCs) are a significant component of overall crashes in the US and Canada. Roads and their traffic also create partial or total barriers to the movement of wildlife, both large and small. There are several well-studied proven mitigation measures that significantly reduce WVCs, provide for safe animal passage across roads, and maintain habitat connectivity. Highly effective measures, such as overpasses and underpasses with fencing can reduce large animal WVCs by over 80% – 100% on average; yet these structures can be costly and there is room for improvement in their design, the use of new materials, adding elements that improve their use by smaller animal species, such as reptiles and amphibians and improving their cost effectiveness. This Transportation Pooled Fund Study, TPF-5(358) (TPF Study), allowed researchers to evaluate the latest information on the effectiveness of 24 different highway mitigation measures designed to decrease collisions with large wildlife, large feral and domestic animals. Also reviewed were these same measures’ ability to protect small mammals, reptiles, and amphibians from collisions. The TPF Study also explored the effectiveness of the 24 measures ability to maintain or enhance habitat connectivity. It conducted 11 different research projects that variously explored a) the costs and benefits of animal-vehicle collisions and the mitigation measures that seek to reduce them, b) the ecological effectiveness of various mitigation measures, and 3) new designs for crossing structures for a variety of species. The project developed a manual of best practices and concluded with a final report.

Texte intégral

Résumé :

The project objective was to more fully understand how the motion of pollen grains may be controlled by electrostatic forces, and to develop a reliable mechanized pollination system based upon sound electrostatic and aerodynamic principles. Theoretical and experimental analyses and computer simulation methods which investigated electrostatic aspects of natural pollen transfer by insects found that: a) actively flying honeybees accumulate ~ 23 pC average charge (93 pC max.) which elevates their bodies to ~ 47 V likely by triboelectrification, inducing ~ 10 fC of opposite charge onto nearby pollen grains, and overcoming their typically 0.3-3.9 nN detachment force resulting in non-contact electrostatic pollen transfer across a 5 mm or greater air gap from anther-to-bee, thus providing a theoretical basis for earlier experimental observations and "buzz pollination" events; b) charge-relaxation characteristics measured for flower structural components (viz., 3 ns and 25 ns time constants, respectively, for the stigma-style vs. waxy petal surfaces) ensure them to be electrically appropriate targets for electrodeposition of charged pollen grains but not differing sufficiently to facilitate electrodynamic focusing onto the stigma; c) conventional electrostatic focusing beneficially concentrates pollen-deposition electric fields onto the pistill tip by 3-fold as compared to that onto underlying flower structures; and d) pollen viability is adequately maintained following exposure to particulate charging/management fields exceeding 2 MV/m. Laboratory- and field-scale processes/prototype machines for electrostatic application of pollen were successfully developed to dispense pollen in both a dry-powder phase and in a liquid-carried phase utilizing corona, triboelectric, and induction particulate-charging methods; pollen-charge levels attained (~ 1-10 mC/kg) provide pollen-deposition forces 10-, 77-, and 100-fold greater than gravity, respectively, for such charged pollen grains subjected to a 1 kV/cm electric field. Lab and field evaluations have documented charged vs. ukncharged pollen deposition to be significantly (a = 0.01-0.05) increased by 3.9-5.6 times. Orchard trials showed initial fruit set on branches individually treated with electrostatically applied pollen to typically increase up to ~ 2-fold vs. uncharged pollen applications; however, whole-tree applications have not significantly shown similar levels of benefit and corrective measures continue. Project results thus contribute important basic knowledge and applied electrostatics technology which will provide agriculture with alternative/supplemental mechanized pollination systems as tranditional pollen-transfer vectors are further endangered by natural and man-fade factors.

Résumé :

The project’s general objectives were to determine specific polymorphisms at the DNA level responsible for observed quantitative trait loci (QTLs) and to estimate their effects, frequencies, and selection potential in the Holstein dairy cattle breed. The specific objectives were to (1) localize the causative polymorphisms to small chromosomal segments based on analysis of 52 U.S. Holstein bulls each with at least 100 sons with high-reliability genetic evaluations using the a posteriori granddaughter design; (2) sequence the complete genomes of at least 40 of those bulls to 20 coverage; (3) determine causative polymorphisms based on concordance between the bulls’ genotypes for specific polymorphisms and their status for a QTL; (4) validate putative quantitative trait variants by genotyping a sample of Israeli Holstein cows; and (5) perform gene expression analysis using statistical methodologies, including determination of signatures of selection, based on somatic cells of cows that are homozygous for contrasting quantitative trait variants; and (6) analyze genes with putative quantitative trait variants using data mining techniques. Current methods for genomic evaluation are based on population-wide linkage disequilibrium between markers and actual alleles that affect traits of interest. Those methods have approximately doubled the rate of genetic gain for most traits in the U.S. Holstein population. With determination of causative polymorphisms, increasing the accuracy of genomic evaluations should be possible by including those genotypes as fixed effects in the analysis models. Determination of causative polymorphisms should also yield useful information on gene function and genetic architecture of complex traits. Concordance between QTL genotype as determined by the a posteriori granddaughter design and marker genotype was determined for 30 trait-by-chromosomal segment effects that are segregating in the U.S. Holstein population; a probability of <10²⁰ was used to accept the null hypothesis that no segregating gene within the chromosomal segment was affecting the trait. Genotypes for 83 grandsires and 17,217 sons were determined by either complete sequence or imputation for 3,148,506 polymorphisms across the entire genome. Variant sites were identified from previous studies (such as the 1000 Bull Genomes Project) and from DNA sequencing of bulls unique to this project, which is one of the largest marker variant surveys conducted for the Holstein breed of cattle. Effects for stature on chromosome 11, daughter pregnancy rate on chromosome 18, and protein percentage on chromosome 20 met 3 criteria: (1) complete or nearly complete concordance, (2) nominal significance of the polymorphism effect after correction for all other polymorphisms, and (3) marker coefficient of determination >40% of total multiple-regression coefficient of determination for the 30 polymorphisms with highest concordance. The missense polymorphism Phe279Tyr in GHR at 31,909,478 base pairs on chromosome 20 was confirmed as the causative mutation for fat and protein concentration. For effect on fat percentage, 12 additional missensepolymorphisms on chromosome 14 were found that had nearly complete concordance with the suggested causative polymorphism (missense mutation Ala232Glu in DGAT1). The markers used in routine U.S. genomic evaluations were increased from 60,000 to 80,000 by adding markers for known QTLs and markers detected in BARD and other research projects. Objectives 1 and 2 were completely accomplished, and objective 3 was partially accomplished. Because no new clear-cut causative polymorphisms were discovered, objectives 4 through 6 were not completed.

Résumé :

• Renewable energy (RE) projects in Indonesia usually have IRR between 10% and 15% and PP around 6 to 30 years • Attractive return usually could be found in large scale RE projects, although there are numerous other factors involved including technology developments, capacity scale, power purchasing price agreements, project locations, as well as interest rates and applied incentives. • Crowdfunding (CF) has big potential to contribute to the financing of RE projects especially financing small scale RE projects. • P2P lending usually targeted short-term loans with high interest rates. Therefore, it cannot be employed as an alternative financing for RE projects in Indonesia. • Three types of CF that can be employed as an alternative for RE project funding in Indonesia.
