User's manual for CONTAIN 1. 0, a computer code for severe nuclear reactor accident containment analysis

The CONTAIN 1.0 computer code is an integrated analysis tool for the physical, chemical, and radiological conditions inside a containment building following the release of radioactive material from the primary system in a severe reactor accident. It can also predict the source term to the environment. Purpose of this User's Manual is to provide a basic understanding of the features and models in CONTAIN 1.0 so that users can prepare reasonable input and understand the output and its significance for particular applications. Besides input instructions, the User's Manual also contains brief descriptions of the basic features of the models. Both light-water reactors and liquid-metal reactors can be modeled with CONTAIN 1.0. The code includes atmospheric models for steam/air thermodynamics, intercell flows, condensation/evaporation on structures and aerosols, aerosol behavior, hydrogen burning, sodium/atmosphere chemistry, sodium-spray fires, and sodium-pool fires. It also includes models for reactor cavity phenomena such as core/concrete interactions, coolant-pool boiling, and sodium/concrete interactions. Heat conduction in structures, fission-product decay and transport, radioactive heating, and the thermal-hydraulic and fission-product decontamination aspects of engineered safety features are also modeled.
Experimental investigations on biologically inspired airfoils for MAV applications

Two experimental studies were conducted to explore the possibilities of biologically inspired airfoils as Micro-Air-Vehicles (MAVs) applications. In the first study, the flow behavior around a corrugated dragonfly airfoil compared with both a traditional streamlined airfoil and a flat plate were investigated. This study was conducted at the chord Reynolds number of 34,000 where MAVs usually operate in order to explore the potential application of such biologically inspired airfoils for MAV designs. The resulting measurements demonstrate clearly that the corrugated dragonfly airfoil has much better aerodynamic performance over both the traditional streamlined airfoil and the flat plate in preventing large-scale flow separation and airfoil stall at the test low Reynolds number level. The second study was conducted to investigate the flow behavior around flexible membrane airfoils compared with a rigid counterpart. The experimental study was conducted at the chord Reynolds number of 80,000, which is also in the MAV operation range. The measurement results demonstrated clearly that the flexible membrane airfoil could have much better aerodynamic performance than a rigid counterpart. Detailed force and PIV measurements have elucidated the underlying physics about how and why the flexible membrane airfoils could have much better aerodynamic performance compared with the rigid counterpart Due to the flexibility, flexible membrane airfoils can change their camber line and reduce its effective angle of attack automatically to adopt the incoming flow to suppress flow separation.
A model for developing and disseminating multimedia materials for teacher educators.

The purpose of this study was to develop a model that would enhance the development, dissemination, and adoption of educational multimedia materials. The grounded theory definition of open coding was used to analyze data collected from the 3-year Technology Leadership Web Library Project at the University of North Texas. Weekly meeting minutes, email communication, reports, notes, questionnaires, and surveys were examined to determine major factors involved in the process of product development and dissemination. From the analysis of this study, five major factors in product development and dissemination were identified. These factors were leadership, team dynamics, expert advisors, feedback, and consumers. The synthesis of the factors led to the development of the PROMOTE (process revolving around ongoing management of team and evaluative feedback) model. The PROMOTE model is based on the establishment of a system that includes leadership, development team, and expert advisors at its center. The system is tied together with well-established feedback loops for stages of evaluation. The PROMOTE model is iterative and uses consumer feedback to generate new products. The PROMOTE model differs from other product development and evaluation models both in the focus of the process and the nature of the evaluation feedback.
On the Relationship between Knowledge, Networks, and Local Context

In this article, we concentrate on the process of value creation within local business networks. We argue that in a local business network the locus of value creation is found within the local context and its ability to create a network of exchange knowledge relations among the various (local) agents. In order to build a model that explains the process of knowledge transfer among individuals and organizations in a local business network, we combine the knowledge based view (Kogut and Zander, 1992; Conner and Prahalad, 1996; Foss, 1996a, 1996b) and the network perspective (Thorelli, 1986; Jarrillo, 1988; Powell, 1990; Uzzi, 1997; Gulati, 1999; Gulati et al., 2000). The knowledge-based view (KBV) within the framework of the resource-based approach is concerned with firm-level analysis; the network approach literature is far more descriptive and seeks to understand how networks affect competition (Nielsen, 2000). It appears that these two approaches are diametrically opposed: the knowledge-based view is exclusively engaged with analysis of the individual firm’s knowledge creation and accumulation, and has nothing to say about inter-firm relations; the primary research interest of the network perspective is, on the other hand, to identify, categorize and theorize relations between firms (networks). We argue that it is indeed feasible for knowledge researchers to draw in a fruitful way on network insights (and vice versa) (Foss, 1999; Dagnino, 1999; Nielsen, 2000). More specifically, the idea of the local business network provides one possible bridge between the two approaches. We will first present a critical review of the knowledge-based theory, which provides an outline of the main theoretical perspectives within this field of research about knowledge transfer, and a review of the network theory approach, which analyses the importance of the relations among different organizations by focusing on the process of sharing and transferring knowledge. A description of our conceptual model, which explains how local context influences the performance of firms belonging to a local business network, follows. Finally, the conclusions and implications for firms and research are discussed.
Orientation analysis for antenna diversity using circular polarization

Traditional polarization diversity systems have relied on the distribution of obstacles within the mobile medium to achieve signal decorrelation and power coupling between orthogonal polarizations. If the channel does not facilitate adequate power coupling, signal diversity is suboptimal because signal contribution from the polarization with lesser power is limited. Further, due to the presence of a dominant polarization, the signal power received in the orthogonal polarizations becomes a function of the transmitter orientation. The use of circular polarization at the transmitter is proposed to facilitate power coupling and alleviate the branch power imbalance between the vertical and horizontal polarizations. The analysis shows that if circular polarization is used, the branch power imbalance between the vertical and horizontal polarizations can be significantly lower than linear polarization, and that the cross polarization discrimination becomes independent of the transmitter orientation. The proposed antenna configuration to achieve circular polarization allows for polarization diversity to be implemented in the uplink and downlink.
Hepatoprotective effect of Tetracarpidium conophorum oil in diclofenac sodium induced hepatotoxicity in rats Primary tabs

Western dietary lifestyle has gained lots of attention globally with high level of patronage hence generating human health concern. This calls for dietary balance and supplementation with vegetables, fish and nuts which are known to contain Omega-3, Omega-6 and Omega-9 fatty acids. Plant based oils such as Walnut (Tetracarpidium conophorum), are known to be rich in Omega-fatty acids, which can help lower pathological conditions such as heart diseases. Therefore, the study investigated the effects of pre-treatment with Tetracarpidium conophorum oil (Oil of African Walnut) in adult male Wistar rats exposed to diclofenac sodium (DFS). Twenty four male rats were randomly divided into four groups of six rats each, this includes: Group 1-Normal control; Group 2DFS control; Group 3low dose Tc oil + DFS; and Group 4high dose Tc oil + DFS. The rats in group 2 received intramuscular dose of DFS (10 mg/kg body weight/day during the last 7 days of T. conophorum oil treatment. Rats in treatment groups 3 and 4 were pre-treated with T. Conophorum oil at 5.0 and 10 ml/kg b.w/day per oral for 21 days, afterwards they were administered DFS at 10 mg/kg b.w/day respectively for 7 days. The result showed that, DFS increased significantly biochemical and pro-inflammatory markers. Pre-treatment with oil of T. conophrum significantly prevented the pathological conditions due to diclofenac. In conclusion, pre-treatment dosing with oil of T. Conophorum could be suggested as a novel adjuvant in long term management of rheumatoid arthritis in man using diclofenac sodium.
Identification and Quantification by Targeted Metabolomics of Antibiotic-Responsive Urinary Small Phenolic Molecules Derived from the Intestinal Microbiota in Mice

Background: Urinary levels of small molecules generated by the gut microbiota (GMB) constitute potential biomarkers for the state of the GMB. Such metabolites include numerous small phenolic molecules linked to anaerobic bacteria, particularly Clostridium species. Due to multiple technical challenges, however, the relationship between these chemicals and the GMB remains poorly characterized. Improved, high-performance liquid chromatography-mass spectrometry (LC-MS)-based metabolomic analysis can now reliably separate and quantify low levels of multiple small phenolic molecules and their structural isomers.Methods: CF-1 (female mice) were treated over 2 consecutive days with either i) vehicle, ii) one of 2 different antibiotic regimens (clindamycin or piperacillin/tazobactam) known to inhibit intestinal anaerobes and promote colonization by Clostridium difficile and other pathogens or iii) an antibiotic (aztreonam) that suppresses facultative Gram-negative bacteria but not enterococci or anaerobes and does not promote pathogen colonization Urine collected 24 hours after the last treatment was analyzed by LC-MS.Results: We identified over 25 compounds, many of which had not been previously reported in mouse urine. Eleven small phenolic molecules showed significant antibiotic-related changes. Urinary levels of the hydroxyphenylpropionic acids were suppressed by clindamycin and piperacillin/tazobactam treatment, but were elevated in aztreonam-treated mice. In addition, aztreonam treatment was associated with elevated levels of the dihydroxyhydrocinnamic acids.Conclusions: Profiles of differential changes in urinary small phenolic molecules may provide an index of anaerobic bacterial species in the GMB and could prove useful in monitoring susceptibility to overgrowth of pathogens such as C. difficile.
Design and control of quadrotors with application to autonomous flying

This thesis is about modelling, design and control of Miniature Flying Robots (MFR) with a focus on Vertical Take-Off and Landing (VTOL) systems and specifically, micro quadrotors. It introduces a mathematical model for simulation and control of such systems. It then describes a design methodology for a miniature rotorcraft. The methodology is subsequently applied to design an autonomous quadrotor named OS4. Based on the mathematical model, linear and nonlinear control techniques are used to design and simulate various controllers along this work. The dynamic model and the simulator evolved from a simple set of equations, valid only for hovering, to a complex mathematical model with more realistic aerodynamic coefficients and sensor and actuator models. Two platforms were developed during this thesis. The first one is a quadrotor-like test-bench with off-board data processing and power supply. It was used to safely and easily test control strategies. The second one, OS4, is a highly integrated quadrotor with on-board data processing and power supply. It has all the necessary sensors for autonomous operation. Five different controllers were developed. The first one, based on Lyapunov theory, was applied for attitude control. The second and the third controllers are based on PID and LQ techniques. These were compared for attitude control. The fourth and the fifth approaches use backstepping and sliding-mode concepts. They are applied to control attitude. Finally, backstepping is augmented with integral action and proposed as a single tool to design attitude, altitude and position controllers. This approach is validated through various flight experiments conducted on the OS4.
Numerical Simulation of the Ion Transport Behavior in Concrete under Coupled Axial Loading and Sulfate Attack

During a sulfate attack on concrete, ions, which are transported to the interior of concrete through pores, react with the concrete components. The transport characteristics are affected by various factors. A chemical-mechanical coupling method for accurately evaluating the transport behavior of sulfate ions in concrete under stress conditions was proposed in this study to investigate the transport characteristics of these ions. The diffusion-reaction equations of sulfate ions were obtained based on the diffusion-reaction approach in combination with the mechanism of volume expansion under a sulfate attack and the influence of load on the concrete voidage. The constitutive response and crack density of the matrix were calculated according to the volumetric strain caused by external load and ettringite growth. Then, the diffusion coefficient of the equation was dynamically corrected. T'his phenomenon was a strongly coupled moving boundary problem, and the equations were solved using numerical method. A case study was conducted to analyze the distribution law of ionic concentration and volumetric strain obtained using the proposed method. Results demonstrate that the crack damage due to volumetric strain plays a major role in the diffusion of sulfate ions. The load has minimal effect on the transport behavior under a low stress level, and the water-cement ratio is negatively correlated with ion transport capacity. The proposed method serves as a reference for evaluating the durability of an underground structure in a sulfate formation.
The One to One Future: Building Relationships One Customer at a Time (Будущее персонализации: построение взаимоотношений с одним клиентом)

The One to One Future revolutionized marketing when it was first published. Then considered a radical rethinking of marketing basics, this bestselling book has become today's bible for marketers. Now finally available in paperback, this completely revised and updated edition - with an all-new User's Guide - takes readers step-by-step through the latest strategies needed for any business to compete, and succeed, in the Interactive Age. Most businesses follow time-honored mass-marketing rules of pitching their products to the greatest number of people. However, selling more goods to fewer people is not only more efficient but far more profitable. The One to One Future is a radically innovative business paradigm focusing on the share of customer - one customer at a time - rather than just the share of market. Authors Don Peppers and Martha Rogers reveal one to one strategies to: * Find the 20 percent - or 2 percent - of your own customers and prospects who are the most loyal and who offer the biggest opportunities for future profit; * Collaborate with each customer, one at a time, just as you now work with individual suppliers or marketing partners; * Nurture your relationships with each customer by relying on new one to one media vehicles - not just the mail, but the fax machine, the touch-tone phone, voice mail, cell phones, and interactive television. Leading-edge companies such as MCI, Lexus, Levi Strauss, and Nissan Canada, and thousands of smaller enterprises, have already adopted the one-to-one perspective. The strategies outlined in this book work just as well - often even better - for small companies, from two-person accounting firms to flower shops to furniture stores.
Thermodynamic Analysis of the Reactions of Sulphur-Containing Compounds in the Process of Diesel Fractions Hydrodesulphurization on the Base of Quantum-Chemical Calculations

On the base of quantum-chemical calculations (DFT, B3LYP, 3-21G), thermodynamic parameters of the reactions of sulfur-containing compounds in the process of diesel fractions hydrodesulphurization were estimated. Based on the thermodynamic analysis, the probability of reactions occurrence was determined, the reaction scheme for hydrocarbon transformations was proposed, which can be used in mathematical modeling. It was shown that thermodynamic probability of the hydrogenolysis reactions increases in the series: dibenzothiophenes (ΔGr=-33.27 kJ/mol), benzothiophenes (ΔGr=-71.36 kJ/mol), thiophenes (ΔGr=-137.20 kJ/mol) and sulfides (ΔGr=-142.64 kJ/mol). It was found that hydrogenolysis of sulfides, thiophenes, and benzothiophenes proceeds irreversibly, and hydrogenolysis of dibenzothiophenes proceeds reversibly through the stage of aromatic hydrocarbons formation, followed by their hydrogenation to cycloparaffins. It was shown that in the series of thiophenes, benzothiophenes, and dibenzothiophenes, the thermodynamic probability of the hydrogenolysis reactions decreases with increasing molecular weight. The values of the enthalpies of the sulfur-containing compounds reactions are calculated, and all reactions were shown to be exothermic. The greatest thermal effect is is observed for reactions of dibenzothiophenes hydrogenation to bicyclic paraffins (ΔHr=-514.89 kJ/mol), reactions of benzothiophenes to cycloparaffins (ΔHr=-398.71 kJ/mol), reactions of thiophenes to paraffins (ΔHr=317.85 kJ/mol.
Relating elementary students' process portfolios to writing self-efficacy and performance

Writing performance is essential for academic success at all levels. To help elementary school students become better and motivated writers, educators need to help them have functional writing self-efficacy beliefs that slightly exceed what a learner can actually accomplish. A suggested way to achieve this is having students create process portfolios to: a) document the writing process and their progress monitoring, b) have access to peers' work and c) receive feedback. This multiple case study explored the development of students' writing performance and writing self-efficacy beliefs through a one-academic-year implementation of process portfolios in three fourth grade elementary school classes (N=63 students) in Cyprus. The students of two fourth grade classes (n2=23, n3=20) created paper-based process portfolios, while in the researcher's class (n1=20) students created digital portfolios. The study explored how process portfolio affordances, such as a process approach in writing, progress monitoring (goal setting, reflection, self-evaluation), access to peers' work and feedback related to students' writing performance and self-efficacy and how this relationship changed over time. It relied on a mixed method (quantitative and qualitative) research methodology comprised of pre- mid-and post- portfolio implementation students' writing performance and self-efficacy tests, teachers' and students' interviews on their perceptions of portfolios and a portfolio artifact analysis. While there is much to understand regarding the impact of portfolios on students' writing performance and writing self-efficacy the results of this study produced several important findings and practical implications related to portfolio use and the added pedagogical benefits of portfolio affordances. The key findings revealed that students' writing performance increased over time. Learning gains were also found in students' ability to provide corrective feedback and constructive comments to their peers' work, to set goals, and to provide accurate self-evaluations of their work. Students' writing self-efficacy increased over time and became more accurate as it reflected students' actual performance by the end of portfolio implementation. Implications for practice and guidelines based on a bottom-up approach that could facilitate a large-scale implementation of digital and paper-based portfolios in Cyprus in the future are offered.
Immobilization of GOx on Trp / Trp-Fc Functionalized Nanospheres: Improved of Reusability and Stability

In the study, new nanospheres support containing ferrocene were synthesized and characterized, then the properties of nanospheres as biocatalysis were researched . Novel support was prepared from (Aminomethyl)polystyrene (AMP), tryptophan (Trp) and ferrocene aldehyde (Fc) and the enzymatic properties of immobilized glucose oxidase enzyme (GOx) was investigated. Modified polystyrene was characterized IR spectra, Gel permeation chromatography and Scanning electron microscopy. Ferrocene-tagged nanospheres-GOx shows high reusability and storage capacity and fast incubation time determination of glucose. After 12 months, immobilized GOx to the AMP-Trp and AMP-Trp-Fc retained ca 20 % and 40 % for their original activity, respectively. High activities were found for modified polymers AMP-Trp-Fc retains more than 35 % of the initial activity after fifteenth successive cycles, which is a perfect performance.
Integrated Circuit Yield Enhancement - Redundant Multi Core DSP Cluster

The manufacturing of integrated circuits is not a perfect fault-free process. The constant downscaling of integrated circuits requiring higher accuracy each generation also allows the designer to fit more transistors in the same area. From a manufacturing point of view, this downscaling introduces additional possible sources of error, which forces a constant struggle to keep the yield or ratio of successfully manufactured chips high enough to be profitable. The manufacturing success ratio, or yield, is a major component of what determines the time and material cost it takes to manufacture an integrated circuit. To increase yield a common approach is to add redundant or spare parts to the system requiring only enough of them to work. Redundancy has long been a common concept in memories. For random logic blocks, the overhead cost has been too large to be reasonable. But for multi core systems, with several instances of the same logic block, the situation is starting to resemble the case of a memory. The manufacturing yield can be predicted by statistical models. Such models may consist of analytical expressions based on very low level information such as the exact layout features of every transistor and wire of the entire chip. However the addition of a spare core for a multi core cluster is an architectural decision that has to be made in the early stages of the design where low level details are not readily available. The modeling approach taken in this project uses a collection of simplified models previously used for yield calculations for memories. The model results in estimates of the yield before and after the addition of redundant cores. The input parameters to the model are based on gate counts and global routing estimates of an early floor plan together with information about the manufacturing process in the form a fault density. When sources of defects are found and suppressed, the yield ramps up. The yield model presented here also shows the effect the redundancy has on the yield ramp, pushing it towards an earlier volume production date, potentially decreasing the product time to market.
