Abstract:
SynopsisStability and asymptotic stability of the null solution of the differential-difference equation (E)x′(t) = f(x(t), x(t − r)), f: RNxRN → RN, f(0, 0) = 0, are studied by means of an extension of the Liapunov–Razumikhin method. Let V: RN → R be a differentiate map, let C = C(+ −r, 0=, RN), and let x(t, ψ) denote the solution of (E) with initial condition ψ in C at t = 0. For t ≧ 0 let xt(ψ) be defined by xt,(ψ)(θ) = x(t + θ, ψ), −r ≦θ ≦0. Let V′ (ψ) be the variation of V along the solution x(t, ψ). We say that V is dichotomic with respect to (E) if there exist T ≧0 and Ω, a neighbourhood of the origin in C, such that if ψ is in the closure of the set where V′ (xT(ψ)) >; 0, then V(x(T, ψ)) ≦ V(x(s, ψ)) for some s, −r ≦ sT. It is proved that if V is positive definite, continuously differentiable, and dichotomic, then the null solution of (E) is stable. A concept of strict dichotomic map is introduced and used to prove asymptotic stability. A number of examples are given to illustrate the applications of the method.

Let T be a triangle.

Given a function f on [0,∞), let E[/(r), U, V] denote the mean value of f(|u–v|), where |u–v| is the distance between u∊U and v∊V. Using Borel’s overlap technique, a specific distance weight function and a specific equivalence relation, we obtain formulae expressing E[f(r), U, V] in terms of triple integrals, expressing E(rn, U, V), E[f(r), A, V] and E[f(r), R, V] in terms of double integrals, expressing E[f(r), A, B], E[f(r), R, S], E[f(r), T, T], E[f(r), P, P], E(rn, C, D) and E(rn, R, V) in terms of single integrals, and expressing E(rn, R, S), E(rn, P, P), E(rn, T, T), E(rn, E, E) in terms of elementary functions, where n is an integer ≧−1.

Abstract:
AbstractIt is shown that the system of the form x + V′ (x) = p (t) with periodic V and p and with (p) = 0 is near-integrable for large energies. In particular, most (in the sense of Lebesgue measure) fast solutions are quasiperiodic, provided V ∈ C(5) and p ∈ L1; furthermore, for any solution x(t) there exists a velocity bound c for all time: |x(t)| < c for all t ∈ R. For any real number r there exists a solution with that average velocity, and when r is rational, this solution can be chosen to be periodic.

Abstract:
An irreversible conversion process is a dynamic process on a graph where a one-way change of state (from state 0 to state 1) is applied on the vertices if they satisfy a conversion rule that is determined at the beginning of the study. The irreversible k -threshold conversion process on a graph G = V , E is an iterative process which begins by choosing a set S 0 ⊆ V , and for each step t t = 1 , 2 , ⋯ , , S t is obtained from S t − 1 by adjoining all vertices that have at least k neighbors in S t − 1 . S 0 is called the seed set of the k -threshold conversion process, and if S t = V G for some t ≥ 0 , then S 0 is an irreversible k -threshold conversion set (IkCS) of G . The k -threshold conversion number of G (denoted by ( C k G ) is the minimum cardinality of all the IkCSs of G . In this paper, we determine C 2 G for the circulant graph C n 1 , r when r is arbitrary; we also find C 3 C n 1 , r when r = 2 , 3 . We also introduce an upper bound for C 3 C n 1 , 4 . Finally, we suggest an upper bound for C 3 C n 1 , r if n ≥ 2 r + 1 and n ≡ 0 mod 2 r + 1 .

Abstract

Problem: The desire for development in less privileged countries like Uganda has created the need for the privileged countries like Sweden to embark on external knowledge transfer through different projects, as one of the objectives to achieve development. However, some factors tend to limit the success of this external knowledge transfer process.

Purpose: The purpose of this research is to find out the factors that lead to the barriers and limitations of knowledge transfer in development projects. Since there are differences in objectives between nonprofit and profit making projects, the research is also aimed at highlighting the extent to which the affecting factors hinder the achievement of objectives and goals.

Method: Qualitative methods were used in this research. Telephone interviews were conducted after sending questionnaires to four respondents from different organizations that were actively involved in the projects. In order to have balanced results, two respondents each from Uganda and Sweden were interviewed. Trustworthiness and ethical issues were put into consideration while conducting the interviews, in a bid to create a desirable atmosphere for conducting the study.

Result: External knowledge transfer is affected by factors like culture, individual factors, and knowledge management factors. Apart from the mentioned factors, research found that instead of organizational factors that would affect profit making projects to a greater extent, factors like the political will, ownership and local needs are the ones that affect development projects.

Conclusion: The factors that affect the external knowledge transfer process are to a greater extent human, and are controllable. In development projects, the recipient country should identify the needs that would initiate the external knowledge transfer process. Most of the affecting factors would be controlled through building of relationships and strong ties, local ownership, and political considerations. All this put into consideration, external knowledge transfer between developed and developing countries stand a high chance to succeed.

This research analyses the TV CÂMARA, a legislative channel of Bauru, a city located in São Paulo, Brazil. Its purpouse is based on a search for the channel s uses, analisyng the programations contents, the process of production and transmition, the social contributions on the contruction of citizen s conscience and finally, its acception by the viewer. The medotological procedures included the participant observation, consisted in follow day by day the TV s activities from March 2002 from February 2003, and July 2003. The documental research had given several informations about the strategies and interviews, which permited the knowledge about comunity participation in the propgrams and the perception about the role of the channel in the city. The fact is that TV CÂMARA has been increasing the options in the local TV broadcasting. The city viewers can see themselves watching the legislative programation. Nevertheless the channel needs to set its existence in the communication field. The society participation can be increased with new programs and more directly, through the guidelines organization. The most important thing is: the legislative channel is a public instrument that must be used by the local population.
Esta pesquisa analisa a TV CÂMARA canal legislativo municipal da cidade de Bauru, SP. Os objetivos foram levantar as formas de uso do canal, analisar o conteúdo da programação produzida e veiculada para a realidade bauruense, suas contribuições sociais na construção da consciência cidadã e a aceitação do canal junto ao telespectador. Os procedimentos metodológicos incluíram a observação participante, que consistiu no acompanhamento interno das atividades do canal de março de 2002 a fevereiro de 2003 e em julho de 2003. A pesquisa documental que ofereceu dados sobre estratégias da programação e entrevistas, as quais permitiram colher informações sobre participação da comunidade nos programas e sua percepção sobre o papel do canal televisivo no município. Conclui-se que o canal abriu um considerável leque de opções na televisão local. A cidade se enxerga quando assiste o canal legislativo. Ainda assim a TV Câmara precisa se solidificar no meio em que atua. A participação da sociedade pode ser ampliada com mais programas e ainda de forma mais direta, inclusive na elaboração de pautas. O mais importante: o canal é um instrumento público.

Abstract:
In un mondo in cui la preoccupazione per l’equilibrio ambientale è sempre più pressante, la rifessione sul rapporto tra spazio urbano e spazio agricolo – e, in particolare, sulle modalità di approvvigionamento delle città e, più specifcamente, sul il commercio alimentare – diventa evidente. L’analisi dello stretto rapporto tra commercio e trasformazione urbana nella città di Lisbona, così come, in particolare, Marvila – un quartiere appartenente alla parte orientale di Lisbona dove, fno a tempi recenti, proliferavano fattorie e orti – ci serve come pretesto per ripensare al ruolo della produzione agricola e del commercio all’interno della struttura cittadina. Attraverso un’analisi dello stretto rapporto tra commercio e trasformazione urbana, si cerca di prevedere come un commercio basato su fliera corta possa trasformare profondamente il modo di vivere dei suoi abitanti. Il carattere frammentato e disperso del territorio di Marvila ci aiuta a immaginare la città alla luce delle infrastrutture che potrebbero trasformare Lisbona in un sistema.

Abstract:
A maneira como as cidades se abastecem e as preocupações ambientais relativas ao sistema alimentar do qual atualmente dependemos têm vindo a suscitar um particular interesse no âmbito da investigação no campo da arquitetura. Tomando como ponto de partida as questões alimentares e as relações que estas estabelecem com o espaço urbano, torna-se então possível repensar as cidades contemporâneas e recuperar o antigo vínculo - que se tem vindo a perder desde o advento da revolução industrial - entre o mundo urbano e o mundo agrícola. As particulares condições naturais da área de Lisboa favoreceram historicamente a prática agrícola no interior do seu território, demonstrando a pertinência de uma abordagem à cidade que tenha como tema central a agricultura. Através do recurso a fontes primárias - como documentos escritos e cartográfcos históricos, é conduzida uma análise com a intenção de traçar de forma pormenorizada a antiga ocupação agrícola do solo da capital. No contexto de Lisboa, a Freguesia de Marvila é identifcada como a área que atualmente apresenta as características naturais e históricas apropriadas para a proposta arquitetónica de um modelo urbano agrícola. A estreita relação que se estabelece com a comida, a partir da produção até a fase de consumo, permite defnir um modo de vida colectivo que disponibiliza novos espaços para a cidade e para os seus habitantes. A comida, em todas as fases do sistema alimentar, torna-se o elemento estruturante na defnição de uma cidade agrícola: o projeto arquitetónico e paisagístico proposto responde às necessidades programáticas e funcionais do modelo de cadeia curta, que pressupõe uma proximidade entre produtor e consumidor, ou seja, entre horta e habitação.
Negli ultimi anni, il modo in cui vengono nutrite le città e le preoccupazioni ambientali relative al sistema alimentare da cui attualmente dipendiamo hanno riscontrato un particolare interesse nella ricerca in campo architettonico. Prendendo come punto di partenza le questioni alimentari e le relazioni che esse instaurano con lo spazio urbano è possibile ripensare le città contemporanee e recuperare l’antico legame tra mondo urbano e mondo agricolo che è andato a perdersi dall’avvento della rivoluzione industriale. Le particolari caratteristiche naturali dell’area di Lisbona hanno storicamente favorito la pratica agricola sul territorio, dimostrando la pertinenza di un approccio alla città che abbia come tema centrale l’agricoltura. Attraverso il ricorso a fonti primarie - come documenti scritti e cartografci storici, viene condotta un’analisi che intende tracciare in modo dettagliato l’antica occupazione agricola sul suolo cittadino. All’interno del contesto di Lisbona, la Freguesia di Marvila viene individuata come l’area che attualmente presenta le caratteristiche naturali e storiche adatte alla proposta architettonica di un modello urbano agricolo. Lo stretto rapporto che si stabilisce con il cibo, dalla produzione alla fase di consumazione, permette di defnire un modo di vivere collettivo che mette a disposizione nuovi spazi per la città e per i suoi abitanti. Il cibo, in tutte le diverse fasi del sistema alimentare, diventa l’elemento strutturante nella defnizione di una città agricola: il progetto architettonico e paesaggistico proposto risponde alle necessità programmatiche e funzionali del modello della fliera corta, che presuppone una prossimità tra produttore e consumatore, quindi tra orto e abitazione.

This study proposes a measurement and assessment model for the construction productivity of freeway reconstruction project, according to on the previous studies of Thomas and the characteristics of the freeway reconstruction project. The model is used on the cases of the freeway No. 1 reconstruction projects and No. 2 new construction project in Taiwan to realize and compare their respective influence factors of the construction productivity. When the model evaluates the threshold construction productivity of the embankment in the cases, the estimate values for the reconstruction projects and the new construction project are 0.048~0.052 MH/ M 3 and 0.025 MH/ M 3 , respectively. In addition, the influence factors in the reconstruction projects and between the reconstruction projects and the new construction project are introduced, leading to the arrangement of improvement methods. The results based on this study can support the use of the model to various constructions to completely establish the threshold construction productivity in construction engineering for the further use of the cost analysis and construction management. The working content factor in the model, however, should be further studied in a future to obtain a better result.

Chaozhong Li of the Shanghai Institute of Organic Chemistry demonstrated (Organic Lett. 2008, 10, 4037) facile and selective Cu-catalyzed β-lactam formation, converting 1 to 2. Paul Helquist of the University of Notre Dame devised (Organic Lett. 2008, 10, 3903) an effective catalyst for intramolecular alkyne hydroamination, converting 3 into the imine 4. Six-membered ring construction worked well also. Jon T. Njardarson of Cornell University found (Organic Lett. 2008, 10, 5023) a Cu catalyst for the rearrangement of alkenyl aziridines such as 5 to the pyrroline 6. Philippe Karoyan of the UPMC, Paris developed (J. Org. Chem. 2008, 73, 6706) an interesting chiral auxiliary directed cascade process, converting the simple precursor 7 into the complex pyrrolidine 9. Sherry R. Chemler of the State University of New York, Buffalo devised (J. Am. Chem. Soc. 2008, 130, 17638) a chiral Cu catalyst for the cyclization of 10, to give 12 with substantial enantiocontrol. Wei Wang of the University of New Mexico demonstrated (Chem. Commun. 2008, 5636) the organocatalyzed condensation of 13 and 14 to give 16 with high enantio- and diastereocontrol. Two complementary routes to azepines/azepinones have appeared. F. Dean Toste of the University of California, Berkeley showed (J. Am. Chem. Soc. 2008, 130, 9244) that a gold complex catalyzed the condensation of 17 and 18 to give 19. Frederick G. West of the University of Alberta found (Organic Lett. 2008, 10, 3985) that lactams such as 20 could be ring-expanded by the addition of the propiolate anion 21. Takeo Kawabata of Kyoto University extended (Organic Lett . 2008, 10, 3883) “memory of chirality” studies to the cyclization of 23, demonstrating that 24 was formed in high ee. Paul V. Murphy of University College Dublin took advantage (Organic Lett . 2008, 10, 3777) of the well-known intramolecular addition of azides to alkenes, showing that the intermediate could be intercepted with nucleophiles such as thiophenol, to give the cyclized product 26 with high diastereocontrol.

Abstract:
The reduction of the lambda calculus to the theory of combinators in Schönfinkel 1924 applies to positive implicational logic, i.e. to the typed lambda calculus, where the types are built up from atomic types by means of the operation A → B, to show that the lambda operator can be eliminated in favour of combinators К and S of each type A → (B → A) and(A → (B →C)) →((A →C)), respectively. I will extend that result to the case in which the types are built up by means of the general function type ∀х : A.B(x) as well as the disjoint union type Ǝх : A.B(x)— essentially to the theory of Howard 1980. To extend the treatment of→ to ∀ we shall need a generalized form of the combinators К and S, and to deal with Ǝ we will need to introduce a new form of the combinator S (whose type turns out to be a general form of the axiom of choice). But also in the present context, if we are to eliminate variables, then not only the lambda operator for forming terms, but also quantification as a variable-binding operation for forming formulas must be analyzed away; so we will need an analogue of the combinators for formulas. As usual, we shall write if for the value s(t) of the function s for the argument t; so rst is (r(s)))(t), etc. Let v be a free variable of type A. We wish to rewrite the formulas B(v), ∀x: A.B(x) and Ǝх : A.B(x), respectively, as B′v, ∀В′ and ƎB′, where B' is a type-valued function on A.

Abstract:
This volume is intended to employ E–pH diagrams to describe the inorganic solution chemistry of the chemical elements. Such diagrams are very useful in numerous fields of investigation, including electrochemistry, analytical chemistry, inorganic chemistry, geochemistry, environmental chemistry, corrosion chemistry, hydrometallurgy, water chemistry, agricultural chemistry, toxicology, biochemistry, chemical engineering, materials science, health physics, and nutrition. It is assumed that the reader is acquainted with the following major topics which are treated in elementary chemistry: stoichiometry, equilibrium, acid–base phenomena, solubility, complexation, elementary thermodynamics, and electrochemistry. In 1923, W. M. Clark and B. Cohen published a paper in which they introduced the idea of plotting the electromotive force as referred to the hydrogen electrode E against the pH for several chemical systems. In 1928, Clark continued to develop this graphical presentation in his text on the determination of pH. The utility of the method was further extended by numerous other investigators such as M. Pourbaix, G. Valensi, G. Charlot, T. P. Hoar, R. M. Garrels, N. de Zoubov, J. Van Muylder, E. Deltombe, C. Vanleugenhaghe, J. Schmets, M. Maraghini, P. Van Rysselberghe, A. Moussard, J. Brenet, F. Jolas, K. Schwabe, J. Besson, W. Kunz, A. L. Pitman, J. N. Butler, P. Delahay, H. Freiser, H. A. Laitinen, L. G. Sillen, P. L. Cloke, and others. In 1963, M. Pourbaix in collaboration with N. de Zoubov published Atlas d’equilibres electrochimiques, a collection of E–pH diagrams for 90 chemical elements. This volume was translated into English in 1966 by J. A. Franklin and published as Atlas of Electrochemical Equilibria in Aqueous Solutions. Subsequently other investigators published computer programs for constructing the diagrams: L. Santoma; B. G. Williams, and W. H. Patrick; P. B. Linkson, B. D. Phillips, and C. D. Rowles; K. Osseo-Asare, A. W. Asihene, T. Xue, and V. S. T. Ciminellie; D. R. Drewes; M. Mao and E. Peters; H-H. Huang and C. A. Young; J. P. Birk and Laura L. Tayer; G. P. Glasby and H. D. Schulz; and Q.

Andreas Pfaltz of the University of Basel and Keisuke Suzuki of the Tokyo Institute of Technology showed (Angew. Chem. Int. Ed. 2010, 49, 881) that the iodohydrin of 1 did not interfere with the enantioselective hydrogenation. J. R. Falck of UT Southwestern developed (J. Am. Chem. Soc. 2010, 132, 2424) a procedure for coupling arene boronic acids with a cyano triflate 3, readily available in high ee from the corresponding aldehyde. Anita R. Maguire of University College Cork devised (J. Am. Chem. Soc. 2010, 132, 1184) a Cu catalyst for the enantioselective C-H insertion cyclization of 5 to 6. Jin-Quan Yu of Scripps/La Jolla established (J. Am. Chem. Soc. 2010, 132, 460) a complementary enantioselective C-H functionalization protocol, converting the prochiral 7 into 8 in high ee. Xumu Zhang of Rutgers University effected (Angew. Chem. Int. Ed. 2010, 49, 4047) enantioselective branching hydroformylation of 9 to give 10. T. V. RajanBabu of Ohio State University established (J. Am. Chem. Soc. 2010, 132, 3295) the enantioselective hydrovinylation of a diene 11 to the diene 12. Gregory C. Fu extended (J. Am. Chem. Soc. 2010, 132, 1264, 5010) Ni-mediated cross-coupling, both with alkenyl and aryl nucleophiles, to the racemic bromoketone 13. Hyeung-geun Park and Sang-sup Jew of Seoul National University used (Organic Lett. 2010, 12 , 2826) their asymmetric phase transfer protocol to effect the enantioselective alkylation of the amide 15. Kyung Woon Jung of the University of Southern California showed (J. Org. Chem. 2010, 75, 95) that the oxidative Pd-mediated Heck coupling of arene boronic acids to 17 could be effected in high ee. Nicolai Cramer of ETH Zurich observed (J. Am. Chem. Soc. 2010, 132, 5340) high enantioinduction in the cleavage of the prochiral cyclobutanol 19. Alexandre Alexakis of the University of Geneva achieved (Organic Lett. 2010, 12, 1988) the long-sought goal of efficient enantioselective conjugate addition of a Grignard reagent to an unsaturated aldehyde 21. Professor Alexakis also established (Organic Lett. 2010, 12, 2770) conditions for enantioselective conjugate addition to a nitrodiene 23. This procedure worked equally well for β-alkynyl nitroalkenes.

Full text
Abstract:
We have measured the low frequency (undamped) electrooptic and piezoelectric coefficients in several photorefractive crystals using interferometric techniques. The electrooptic and piezoelectric measurements were independent of the frequency (in the range from 10 Hz to 100 kHz) and linear in the magnitude (in the range from 0.1 to 200 V/cm) of the applied electric field. The electrooptic coefficients measured in melt-grown BaTiO3 single crystals at λ = 5145 Å and at T = 23°C are r13 = 33 ± 2 pm/V and r33=124 ± 6 pm/V. The piezoelectric coefficient d13 = 57 ± 3 pm/V was measured separately. The combined Pockels coefficient r C = 84 ± 5 pm/V was measured independently and is in good agreement with the value r c ≡ r33 − (n1/n3)3r13 = 84 ± 5 pm/V computed from the above values of r13 and r33. (n1, and n3 are the ordinary and extraordinary indices of refraction, respectively, of tetragonal BaTiO3.) Similar measurements at λ = 5145 Å in Sr0.6Ba0.4Nb2O6 single crystals yield the electrooptic coefficients r13 = 55 ± 3 pm/V, r33 = 224 ± 11 pm/V, and the piezoelectric coefficient d13 = 47 ± 3 pm/V. The electrooptic and piezoelectric coefficients of LiNbO3 single crystals were also measured. As an independent check on this data, we also measured the coupling between two optical beams in these photorefractive crystals. The ratio of the measured coupling strengths for different optical polarizations agrees with theory using the electrooptic coefficients measured above.

Abstract:
In a world stressed by a cultural crisis, carachterised by excessive abstraction and virtuality (ex: R.Reich’s Symbolic-analysts or/and R. Florida’s Creatives), observing self built city constitute not an escape but an exploration to change our point of view and find a new path of development. Self building involves at any scale, a practical attitude and return to an psychosomatic interaction among inhabitants and built environment. Focusing in self-building can become a Slowskij’s “estragement” to reactivate different sensibilities, for a new philosophy in contemporary design. Morphological reading of self-built environments has a double importance: for self-built cities themselves, to give response to the need of social cohesion, for a restructuring that traduces these needs into building and transforms the plural individual needs into a collective urban structure; for the enrichment that this reading can give to the architectural community culture, a new panorama where we can search new path to go over the crisis; The paper focuses on the scales that goes from building and construction material scale to urban fabric scale. Starting from the observation of a brick’s furnace, through the observation of an original constructive system, up to the aggregation of each built organism in the urban fabric it will be possible to read and interpret the formative process and to evaluate, through design experience cases, some new path for the contemporary design that come from this interpretation of self-built: design as a formative process re-activation, artisanal-not authorial sensorial design; References G.

Abstract:
To choose the adequate regenerator, that gives the highest Stirling engine performances, different compromises must be considered. The figure of Merits is a powerful tool to evaluate and compare the performance of different Stirling engine regenerator matrices. The figure of merits is usually defined as the ratio between the heat transfer performance and the pressure drop losses through the regenerator matrix. The figure of merits can be obtained too by calculating different rations of pressure drop ΔPPm of regenerator volume VdrVE and for regenerator loss Q.tQ.r F M S C = 1 Δ P P m V d r V E Q . t Q . r In this study the experimental results of various Gamma Stirling engine metallic wire regenerator matrices are presented. The figure of merit parameter will be estimated to determine the adequate regenerator. Then the FMSC was used to determine the best regenerator porosity and the optimal operation parameters.

Full text
Abstract:
This work presents an investigation of the ductile tearing properties for API 5L X70 and X80 pipeline steels using experimentally measured crack growth resistance curves (J-R curves). Testing of the pipeline steels employed compact tension (C(T)) fracture specimens to determine the J-R curves based upon the unloading compliance method using a single specimen technique in accordance with the ASTM E1820 standard procedure. Conventional tensile tests and Charpy V-Notch tests were also performed to determine the mechanical and impact properties for the tested materials. Severe splitting running parallel with the crack propagation path with varied lengths was observed in all tested fracture specimens, particularly for the API X80 material. The occurrence of splits makes the determination of JIc and resistance curves more difficult, as delamination of interfaces positioned normal to the crack front decreases the effective thickness of the test piece, inducing plane stress conditions deep inside the specimen. This experimental characterization provides additional toughness and mechanical data against which the general behavior of X70 and X80 class pipeline steel can be compared.

What we are trying to accomplish is the development of some equation with a mathematical underpinning that can usefully relate Functionality, Cost, Schedule and Risk which can then be graphed, and this graph then becomes a decision making and communications aid. For some of us, the current contention is that a possible IPL is analogous to the Ideal Gas Law (IGL), which relates Pressure (P), Volume (V) and Temperature (T) for reasonably well-behaved gases. (P*V)/T = Constant (where the constant has very much to do with the nature of the gas under discussion). This is due to our belief that the IPL will represent some form of a relationship (inverse or direct) between Cost (C), Schedule (S), Functionality (F) and Risk (R) much like the IGL represents relationships between P, V and T for a given gas. We also expect that at least some of the factors will change based on the type of project, so we might have to develop a range of factors and constants. The Ideal Gas Law informs us, for example, that if you keep V fixed and increase P, then you can expect T to also increase. So “keep this one factor fixed, and change that other factor and then watch the third factor move one way or the other” relationships can be described via the Ideal Gas Law. We believe that this “push on one factor and see what happens to the other factors” feature of the Ideal Gas Law seems to be very analogous to project and operation Cost, Schedule, Functionality and Risk relationships. This law, or some such function, is absolutely essential. Having such a Law that is proven valid will introduce (or rather tactfully enforce) some systematic thinking in the project and operational management set-up. Otherwise, no matter how elaborate a case is made for project or operational risks, the risk decisions will be left to the whims, fancies and moods of the key decision-making person(s) in the organization or project — we are working towards reducing this subjectivity in decision-making. We may determine that it is impossible to have a 100% scientific outlook on project or operational factors simply because human beings are involved, but if that is the case, we may be able to be at least 80% scientific about it.

Abstract:
Abstract In this work an experimental study of spray cooling using monodispersed droplet sprays impinging on a flat and heated surface is reported. The aim of the work was to formulate an empirical model describing the heat flux (HF) for the nucleate boiling regime. Monodispersed water droplets with a known diameter and velocity, produced by a droplet generator, were directed toward a heated surface and the heat transfer was registered using a data acquisition system. The resulting high heat flux was investigated as function of the droplets’ diameter and velocity, mass flow rate, ambient pressure, subcooling degree and surface roughness. The resulting matrix of variables investigated in the experiments included; mass flux rate (340 &lt; ṁ″ &lt; 750 kg/m2s), subcooling degree (25 &lt; Tsub &lt; 78 °C), ambient pressure (1 &lt; P &lt; 1.8 bar), and surface roughness (79 &lt; Rt &lt; 5 μm). A generalized correlation was developed for the dimensionless HF as function of the dimensionless mass flow rate, temperature, surface roughness and pressure, along with the Jacob number. The form of the correlation is q ˙ ″ ρ V h f g = 0.245 ( Ja ) 1.038 ( Δ T sub Δ T sat ) 0.491 ( ρ σ m ˙ μ 3 ) 0.133 ( R t D ) 0.0213 ( P P 0 ) 0.291 having a confidence level greater than 95%, the differences between predicted and experimental HF were less than ±19%.

Abstract:
In the last phase of the core degradation, an oxidic melt pool of mainly UO2, ZrO2, and unoxidized Zircaloy and stain-less steel will form in the lower head of the RPV (Theofanous et al., 1996). A molten metal layer (composed mainly of Fe and Zr) will rest on the top of the crust of the oxidic pool. A thin oxidic crust layer of frozen core material is formed on the vessel’s inside wall. In this bounding configuration, thermal loads to the RPV walls are determined by natural convection heat transfer driven by internal heat sources. Decay heat from fission products is assumed to be generated uniformly within the oxidic pool and generally no heat generation is considered in the upper metallic layer. For example, in a hypothetical severe accident scenario for an AP600-like reactor, the following values can be expected: volumetric heat generation Qv ∼ 1 MW/m3, volume of the oxidic pool V ∼ 10 m3, radius R = 2 m, temperatures in the oxidic pool T ∼ 2700°C, temperatures in the metal layer T ∼ 2000°C, maximum depth ratio of the metal layer to the oxidic pool L12 ∼ 0:3, properties of the oxidic pool, depending on melt composition, as characterized by the Prandtl number, Pr ∼ 0:6, properties of the metallic layer Pr &lt; 0:1, the intensity of convective motion, as characterized by the Rayleigh number, Ra ∼ 1015–1016 (Theofanous et al., 1996). The time scale of core melt pool formation is estimated as 1/2 to 1 hour (Sehgal, 1999). Indeed, these estimates could vary, depending very much on the accident scenario and the type of reactor.

Abstract:
Abstract A research and development program was outlined in June 1998 by the CEA’s Rhône Valley Research Center (Valrhô) to model the initial alteration rate r0 between 100°C and 50°C, and the long-term alteration rate r(t) over one year at 50°C, throughout the composition range for the UOX1 “light water” borosilicate containment glass as specified for the R7 and T7 vitrification facilities in the COGEMA reprocessing plant at La Hague. An experimentation plan methodology was set up for this purpose. Seven groups of glass components were designated to assess the influence of composition variations: SiO2, B2O3, Na2O, Al2O3, additive oxides (Fe2O3+NiO+Cr2O3), insoluble fine particle suspensions, and fission product and actinide oxides. The other glass constituents, accounting for 9.5 oxide wt% of the composition, were maintained constant. An empirical synergistic mixing model was postulated, based on first-degree terms and enriched with second-degree terms corresponding to the major interactions liable to exist between some constituents. The NEMROD calculation code was used to select the 22 glass compositions necessary to construct the model (i.e. to determine the values of the 15 coefficients) and the 3 control compositions. The initial rates for all 25 glass compositions were measured in pure water using a Soxhlet test device at 100°C, and in static mode at 50°C. The alteration rates at an advanced degree of reaction progress were determined in static mode at 50°C with a glass-surface-area-to-solution-volume (S/V) ratio of about 60 cm−1. The rates after one year are now available, but the tests are still in progress in order to confirm the stability over time of the steady-state conditions observed. The test results show that the initial alteration rates are clustered around the value obtained for the SON 68 reference glass composition (about 2.4 g·m−2d−1 at 100°C and 0.031 g·m−2d−1 at 50°C), with minor variations between 1.2 and 3.4 g·m−2d−1 at 100°C and between 0.012 and 0.058 g·m−2d−1 at 50°C. These slight rate variations are of considerable significance in view of the wide range of glass compositions investigated. The one-year alteration rates for the test glasses varied by a factor of about 11 around a mean value of 1 × 10−4 g·m−2d−1 at 50°C. The rate variations were modeled as a function of the glass composition variations using the NEMROD program. Other parameter values determined during static testing at the high S/V ratio were also modeled to improve our understanding of the phenomena involved: notably the altered glass thickness after one year. The order of importance of the constituents on the initial rate is not the same as for the final rate, suggesting that the alteration kinetics are controlled by different mechanisms. The initial rate was influenced primarily by the following constituents (by order of importance): the fission product oxides and SiO2 (increasing durability at increasing concentrations) and B2O3 (diminishing durability at increasing concentration). Conversely, the one-year alteration rates were found statistically to depend much more on the variability of the Na2O, Al2O3 and FP oxide concentrations than on the SiO2 concentration. Several hypotheses are proposed to account for these effects.
