THE USE of biological agents, such as bacteria, fungi, plant material, and insects, is proposed as a viable design methodology that can include end-of-life material treatment and re-use as part of the design process. Decay, typically thought of as a destructive process with spatially and temporally unpredictable results can be potentially designed to high levels of spatial and temporal tunability, such that the product of decay can still be of value to the designer. In particular, could microbes, in combination with water, be guided to selectively disintegrate, and potentially also then be harnessed as agents of assembly, enabling design construction instead of destruction? What would the ecology of this system that includes the microbes, biocompatible substrate, and contextual environment, look like? How might it behave and how might this affect how architects design the built environment? The main goal of this thesis is to understand how water-induced decay of biocomposite-based artifacts might be designed such that the deterioration process has use-value for the designed artifact and how this decay might be harnessed as a formative agent instead of only as a deconstructive one. This understanding will be informed by the execution and analysis of a series of case study projects that include: Aguahoja: Artifacts and Hexes Aguahoja: Colonization Aguahoja: Pavilion For these projects, water-based composites of chitosan, cellulose, and pectin, will be additively printed into architectural-scale artifacts and panels which are used as the skin of a small pavilion. The use of the chitin-cellulose-pectin composite introduces a water-dependent biocompatible material system that can act as the base scaffold for biofilms and microbial colonies. A series of material characterization tests were done to understand the nuances of the different bio-composites. Working challenges for this system included warping and uncontrolled deflections due to changing relative humidity and the gradual and constant dehydration of the material. This hydration dependent activity also dictated flexibility rigidity, and colour. Water is used to initiate the disintegration of the panels as well as initiate the growth of microbial cultures on the panels. The projects described here are intended to serve as examples of how a designer might be able to incorporate biological agency into her process. It is not intended as a comprehensive guidebook, but rather as case studies of how one might use nascent biological tools in current design methodology and how that methodology might have to change in order to leverage biology in her process.

The medium format photographs created in conjunction with my senior thesis exhibit, Everyday Decay, use texture, line, intimate framing, warm color palettes, and layering to explore an aspect of the everyday landscape that we interact with often but generally ignore. The choice of medium and subject of decay creates a sense of the past, aided by the warm tones that imply affinity and nostalgia.

The intention of the project is to create an environment where the viewer can explore and form a personal narrative in the process of organic interaction with the work. At first glance, the scale of the installation will attract the viewer to the exhibition, however, upon close investigation he will discover there is deterioration, decay, and mutation. The ideas of time, beauty, decay, mortality, and interdependence will be discussed in this paper. The visitors are invited to interact with the work. I hope through spontaneous interaction the arrangements from the viewer will result in evolution of the work. The balance and tension between patterns and evolution, between creativity and predictability will evolve naturally. I hope the viewer can build a meaningful experience based on his or her cultural, intellectual, and social background through interacting with the installation.

Full textAbstract:
The long time energy decay of vortices for several different initial flow scenarios is investigated both theoretically and numerically. The theoretical analysis is based on the energy method. Numerical calculations are done by solving the compressible Navier-Stokes equations using a high order stable finite difference method. The simulations verify the theoretical conclusion that vortices decay at a slow rate compared to other types of flows. Several Reynolds numbers and grid sizes in both two and three dimensions are considered.

Full textAbstract:
Interactions between copper and chlorine disinfectants were examined from the perspective of disinfectant decay and copper pitting corrosion. Sparingly soluble cupric hydroxide catalyzed the rapid decay of free chlorine, which in turn, led to production of less soluble and more crystalline phases of cupric hydroxide. The catalytic activity of the cupric hydroxide was retained over multiple cycles of chlorine dosing.
Experiments with chloramine revealed that copper species could also trigger rapid loss of chloramine disinfectant. In copper pipes, loss of free chlorine and chloramine were both rapid during stagnation. Reactivity of the copper to the disinfectants was retained for weeks. Phosphate tended to decrease the reactivity between the copper pipe and chlorine disinfectants.
A novel, inexpensive and real-time test to monitor copper pitting corrosion was developed. In a normal pipe, it is not possible to measure the electron flow or pitting current from the pit anode to the cathode. But a new method was developed that can form an active pit on the tip of a copper wire, which in turn, allows the pitting current to be measured. Preliminary experiments presented herein have proven that this technique has promise in at least one water condition known to cause pitting. The method also quickly predicted that high levels of orthophosphate could stop pitting attack in this water, whereas low levels would tend to worsen pitting. Future research should be conducted to examine this technique in greater detail.Master of Science

Maneu, Victoria Jordi. "Decay of Doubly Strange Hypernuclei." Doctoral thesis, Universitat de Barcelona, 2019. http://hdl.handle.net/10803/668372.
Full textAbstract:
Double § hypernuclei are bound systems of several nucleons and two § hyperons. These systems are unstable with respect to the weak interaction and chiefly decay through two-body processes that conserve neither parity, isospin or strangeness. Among such processes we can find those mediated by the
§N ! NN, §§ ! §n and §§ ! ßN reactions but also, thanks to the baryon channel mixing (§N ° ßN, §§ ° •N,§§ ° ßß) made possible by the strong interaction, the weak ßN ! NN, •N ! §n, •N ! ßN, ßß ! §n and ßß ! ßN channels.
This work completes the study of the decay of double-§ hypernuclei by taking into account the microscopic effects of the strong interaction on two baryon states in strangeness sectors -2, -1 and 0, pertaining to the possible baryon-baryon states appearing in the initial and final states, as previously stated. The initial strangeness °2 wave function is obtained from the solution of a G-matrix equation with the input of realistic strong baryon-baryon potentials, while the final hyperon-nucleon wave functions are derived analogously from a microscopic T-matrix calculation. Consequently the opening of the channel induced by the •N pair (with a lower energy threshold than that corresponding to the ßß pair) had to be considered. In order to evaluate these new decay channels the potential that governs the •N interaction with a strangeness variation |¢S|= 1 had to be derived for its incorporation in the study of the decay of 6He. This potential is based on the meson exchange model and includes fundamental states of the pseudoscalar and vector octets.
v
The inclusion of •° p and •0 n states required the derivation of new coupling constants using chiral Lagrangians and SU(3) flavour symmetry (extended to SU(6) spin-flavour symmetry for vector mesons), as well as the construction of new operational structures to account for the different isospin transition channels.
The new §§ ! YN decay rate studied in this work, with YN = §n, ß0 n and ß° p,
represents 3-4% of the total one-baryon induced non-mesonic decay and is remarkably affected by strong interaction effects. In particular, the relative importance of the partial decay rates, encoded in the ratio °§n/(°ß0 n + °ß° p), gets inverted when the mixing to •N
states is incorporated in the initial correlated §§ wave function. This sensitivity can be
used experimentally to learn about the strong interaction in the strangeness °2 sector.Els hipernuclis doble-§ són estats lligats de nucleons i dos hiperons quests estats són inestables en front de la interacció feble, i es desintegren majoritàriament a través de processos a dos cossos que no conserven paritat, isospín ni estranyesa. Entre aquests processos tenim els que venen donats per les reaccions NNN, n i N, però també, i gràcies a la interacció forta que permet la barreja de canals bariònics (NN, N, ), pels canals febles NNN, Nn, NN, n i N. En aquesta tesi s’ha completat l’estudi d’aquests hipernuclis, tenint en compte els efectes microscòpics de la interacció forta per als estats de dos barions en el sector d’estranyesa -2, -1 i 0, corresponents als possibles sistemes barió-barió que apareixen als estats inicial i final esmentats al paràgraf anterior. Per al cas de les partícules lligades en un nucli s’ha resolt una equació de matriu-G mentre que per als sistemes finals s’ha resolt una matriu-T, ambdos casos sota la consideració de potencials barió-barió moderns i realistes, i que ens proporcionen la funció d’ona acoblada per al sistemes inicial i final respectivament. S’ha hagut de considerar doncs l’obertura del canal induït per la parella N, amb un llindar energètic més baix que el corresponent a la parella . Per tal de considerar els nous canals que apareixen en tenir en compte aquesta parella s’ha hagut de derivar el potencial feble a dos cossos que regeix la interacció ΞN amb canvi d’estranyesa |N amb canvi d’estranyesa |S|=1, per tal d’incorporar-lo en el càlcul de la desintegració del 6He. La inclusió de les transicions febles corresponents als estats intermedis ΞN amb canvi d’estranyesa |0 n i ΞN amb canvi d’estranyesa |- p necessita del càlcul de noves constants d'acoblament, les quals s’han derivat utilitzant Lagrangians quirals i simetria de sabor SU(3) (estesa a simetria de sabor-espín S(6) per als mesons vector), així com la construcció d’estructures operacionals que donin compte de les noves transicions que apareixen a l’espai d’espín isotòpic. La nova taxa de desintegració corresponent a YN representa el 3-4% del decaïment no-mesònic induit per un sol barió i es veu afectada considerablement per la interacció forta. En particular la importància relativa dels rates parcials es veu invertida quan s’incorpora l’acoblament a estats N en la funció d’ona correlacionada inicial. Aquesta sensibilitat pot ser usada per a estudiar la interacció forta en el sector d’estranyesa -2.

Full textAbstract:
The non-trivial structure of the QCD vacuum gives rise to a P and CP violating term in the QCD Lagrangian. The fact that we do not see an observable CP violation in the strong interaction despite this CP violating theta term is called the Strong CP Problem. In this thesis, we analyze an observable consequence of this theta vacuum term in the decay of the ground state neutral Sigma hyperon. Due to the SU(3) flavor symmetry, the current upper bound of the neutron electric dipole moment can be translated to an angular asymmetry in the decay distribution of the Σ0 particle. The selfanalyzing weak decay of the Λ hyperon means that any P violation in the initial Σ0 → Λγ decay will result in an asymmetry in the angular distribution of the final decay products. Studying the Sigma and anti-Sigma hyperon decays, we get an idea of C and CP violation in the decay chain. The effect of the production process of the Σ0 hyperon on the angular distribution of the final products is also worked out. A significant angular asymmetry in the decay will mean not only physics beyond the Standard Model, but also physics beyond the CP violating term in the QCD Lagrangian

Full textAbstract:
Decay and accumulation of blanket peat in the Northern Pennine region of England are considered, both in quantitative and qualitative terms. Productivity on the surface of these peat bogs is not unusually high, suggesting that a low decay rate may be responsible for the accumulation of the peat. Considerable study has formerly been made of the aerobic decay processes, at the expense of the parallel anaerobic processes, which have largely hitherto been considered negligible. Yet a current mathematical model of peat accumulation suggests that it is likely to be the anaerobic decay rate which determines the total depth of peat which may accumulate. Further, such models intimate that a very small absolute change in the anaerobic decay rate will have an unexpectedly large effect on the potential steady state depth of peat. The present study concentrates on obtaining measurements of anaerobic decay rates, and on identifying the possible limiting environmental factors of the decay. The design of a sampler to collect gas samples in situ from blanket peat is described. The components of particular interest in the samples are CH4 and C02. Gas concentrations down eight peat profiles at two sites are monitored over two seasons. Simultaneous surface flux measurements above pool, lawn and hummock microhabitats are also made. Water level, temperature, pH, redox potential, depth of the sulphide zone and total sulphide concentration are recorded on each field visit. The results from the gas sample analyses are discussed in relation to the environmental factors and in relation to our present understanding of peat decay rates and their consequences on peat accumulation. The anaerobic decay rate is calculated, and is confirmed to be several orders of magnitude less than that in the overlying aerobic peat. It is shown that the methane is not fossil, but is continually being produced at all depths. Rates of gas production are calculated. Annual methane and carbon dioxide losses from entire peat bogs are calculated to contribute a significant amount to carbon cycling, on a site-specific and global scale.

Full textAbstract:
This thesis is concerned with quantum mechanical decay processes and their mathematical description. It consists out of three parts:
In the first part we look at Laser induced ionization, whose mathematical description is often based on the so-called dipole approximation. Employing it essentially means to replace the Laser's vector potential $\vec A(\vec r,t)$ in the Hamiltonian by $\vec A(0, t).$ Heuristically this is justified under usual experimental conditions, because the Laser varies only slowly in $\vec r$ on atomic length scales. We make this heuristics rigorous by proving the dipole approximation in the limit in which the Laser's length scale becomes infinite compared to the atomic length scale. Our results apply to $N$-body Hamiltonians.
In the second part we look at alpha decay as described by Skibsted (Comm. Math. Phys. 104, 1986) and show that Skibsted's model satisfies an energy-time uncertainty relation. Since there is no self-adjoint time operator, the uncertainty relation for energy and time can not be proven in the same way as the uncertainty relation for position and momentum. To define the time variance without a self-adjoint time operator, we will use the arrival time distribution obtained from the quantum current. Our proof of the energy-time uncertainty relation is then based on the quantitative scattering estimates that will be derived in the third part of the thesis and on a result from Skibsted. In addition to that, we will show that this uncertainty relation is different from the well known {\it linewidth-lifetime relation}.
The third part is about quantitative scattering estimates, which are of interest in their own right. For rotationally symmetric potentials having support in $[0,R_V]$ we will show that for $R\geq R_V$, the time evolved wave function $e^{-iHt}\psi$ satisfies
\begin{align}\nonumber
\|\1_R e^{-iHt}\psi\|_2^2\leq c_1t^{-1}+c_2t^{-2}+c_3t^{-3}+c_4t^{-4}
\end{align}
with explicit quantitative bounds on the constants $c_n$ in terms of the resonances of the $S$-Matrix. While such bounds on $\|\1_R e^{-iHt}\psi\|_2$ have been proven before, the quantitative estimates on the constants $c_n$ are new. These results are based on a detailed analysis of the $S$-matrix in the complex momentum plane, which in turn becomes possible by expressing the $S$-matrix in terms of the Jost function that can be factorized in a Hadamard product.Gegenstand dieser Arbeit ist die mathematische Beschreibung von quantenmechanischen Zerfallsprozessen. Im ersten von drei Teilen, werden wir die durch Laser induzierte Ionisation von Atomen untersuchen, die üblicherweise mit Hilfe der sogenannten Dipolapproximation beschrieben wird. Bei dieser Approximation wird das Vektorpotential $\vec A(\vec r,t)$ des Lasers im Hamiltonoperator durch $\vec A(0, t)$ ersetzt, was oft dadurch gerechtfertigt ist, dass sich das Vektorpotential des Lasers auf atomaren Längenskalen in $\vec r$ kaum verändert. Ausgehend von dieser Heuristik werden wir die Dipolapproximation in dem Limes beweisen, in dem die Wellenlänge des Lasers im Verhältnis zur atomaren Längenskala unendlich groß wird. Unsere Resultate sind auf $N$-Teilchen Systeme anwendbar. Im zweiten Teil wenden wir uns dem Alphazerfallsmodell von Skibsted (Comm. Math. Phys. 104, 1986) zu und beweisen, dass es eine Energie-Zeit Unschärfe erfüllt. Da kein selbstadjungierter Zeitoperator existiert, kann die Energie-Zeit Unschärfe nicht auf gleiche Weise wie die Orts-Impuls Unschärfe bewiesen werden. Um ohne einen selbstadjungierten Zeitoperator Zugriff auf die Zeitvarianz zu bekommen, werden wir mit Hilfe des quantenmechanischen Wahrscheinlichkeitsstroms eine Ankunftszeitverteilung definieren. Der Beweis der Energie-Zeit Unschärfe folgt dann aus einem Resultat von Skibsted und aus den quantitativen Streuabschätzungen, die im dritten Teil der Dissertation bewiesen werden. Darüber hinaus werden wir zeigen, dass diese Unschärfe von der {\it linewidth-lifetime relation} zu unterscheiden ist. Hauptresultat des dritten Teils sind quantitative Streuabschätzungen, die als eigenständiges Resultat von Interesse sind. Für rotationssymmetrische Potentiale mit Träger in $[0,R_V]$ werden wir für alle $R\geq R_V$ die Abschätzung \begin{align}\nonumber \|\1_R e^{-iHt}\psi\|_2^2\leq c_1t^{-1}+c_2t^{-2}+c_3t^{-3}+c_4t^{-4} \end{align} beweisen und darüber hinaus, das ist das Novum, quantitative Schranken für die Konstanten $c_n$ angeben, die von den Resonanzen der $S$-Matrix abhängen. Um zu diesen Schranken zu gelangen, werden wir die analytische Struktur der $S$-Matrix studieren, indem wir die Beziehung der $S$-Matrix zur Jost-Funktion ausnutzen und die wiederum in ein Hadamard-Produkt zerlegen.

Full textAbstract:
mRNA decay is an important step in the control of gene expression. To study mRNA degradation I have exploited the genetic, biochemical, and molecular tools available in Saccharomyces cerevisiae. These studies provided insight into the signals within individual transcripts which specify their half-lives, the various mechanisms by which mRNAs are degraded, and the trans-acting factors which both perform and control nucleolytic events. I identified a 65 nucleotide segment from the coding region of the unstable MATɑl mRNA which was capable of targeting both the MATɑl and stable PGKI transcripts for rapid degradation. This "instability element" was divided into two parts, one located in the first 33, and the second in the latter 32, nucleotides. The first part could be functionally replaced by different mRNA sequences containing rare codons, and while unable to promote mRNA decay by itself, enhanced degradation mediated by the second part. I determined that the MATɑl Instability Element (MIE) targets mRNAs for rapid degradation by increasing the rates of two nucleolytic steps in a pathway of mRNA decay common to several stable and unstable yeast transcripts. The initial step in this pathway is shortening of the poly(A) tail of an mRNA. Subsequently, mRNAs are decapped, after which the transcript body is degraded in a 5' to 3' exonucleolytic manner. The MIE promotes decay of the MATɑl mRNA through an increase in its decapping rate. In contrast, PGKI mRNA decay was stimulated through an increase in its rate of deadenylation. The observation that the poly(A) tail must be removed prior to mRNA decapping suggests that the poly(A) tail inhibits decapping. I determined that the major poly(A)binding protein (Pablp) is required for the inhibition of decapping mediated by the poly(A) tail. Pablp is also required for normal deadenylation rates. Pablp therefore affects mRNA decapping and deadenylation, the two rate determining steps in a common pathway of mRNA decay. Determining how Pablp, and additional trans-acting factors, exert influence over both decapping and deadenylation will provide a greater understanding of the basis of differential rates of mRNA degradation.

Full textAbstract:
Different modifications, namely hexanolylation, acetylation, thennal modification and silylation by trimethoxy vinyl silane (VTMS,) and by 'Y-methacryloxy propyl silane (TMPS) were applied to impart decay resistance to Corsican pine sapwood, which is a non-durable wood. The possible mechanisms by which the modifications impart decay resistance to the wood were also investigated. The silanes applied in this study showed completely different reactivity so that the vinyl group of VTMS remained un-reacted and the vinyl group of TMPS reacted (but its sHanol was not very reactive). The decay resistance of the modified woods were assessed by soft rot, brown rot and white rot fungal tests. The decay resistance against basidiomycetes and soft rot fungi was improved by all the wood modifications applied in this study, but the wood treated with methanolic solutions of the silanes did not show complete decay resistance against brown rot fungi. The failure of the silanes to impart complete protection of wood against brown rot fungus (c. puteana) was attributed to the restriction of the silanes in penetrating into the cell wall. In the soft rot tests, VTMS modified stakes showed high decay resistance but TMPS modified wood showed a moderate decay resistance. This was attributed to the uneven distribution of TMPS in wood. An industrially acceptable treatment method (by using aqueous solutions of silane instead of methanolic solutions and pressure treatment instead of vacuum treatments was established). The perfonnance of the silane treated wood was assessed by field tests. The method worked well with TMPS (the wood showed significant decay resistance in the test) but it didn not work with VTMS. Since both anhydrides (hexanoic and acetic anhydride) used in this study, showed nearly the same perfonnance against C. puteana and soft rot fungi, it was concluded that the improvement in decay resistance against the brown rot fungi and soft rot depends on the WPGonly. Heat treatment above 200°C was recognised to be an effective treatment in improving the decay resistance of wood. It was shown that heat treatment temperature plays a more important role in the improvement of decay resistance than the treatment time. Heat treatment at 250°C for 2 hours, imparted complete decay resistance to the wood against basidiomycetes and soft rot. No significant difference between decay resistance of heated wood post-extracted and heated wood without any extraction against basidiomycet and soft rot fungi was obtained, suggesting that extractable fungicidal is not the reason for the improved decay resistance. In addition to the decay tests, dimensional stability, pore cell wall pore accessibility and hygroscopicity of the modified wood were also studied to find the mechanism by which the modification imparts decay resistance to the wood. It was suggested that hexanoylation and acetylation reduces hygroscopicity so that not enough water is available for the diffusion of brown rot degrading agents into the cell wall, while lignin substitution might be the main reason for the improved decay resistance against white rot fungi. For heated wood, a good correlation between a reduction in FSP and WL due to decay was obtained. Thus, it was suggested that a reduction in the hygroscopicity of wood could be the main reason for the improved decay resistance. By using the Hailwood Horrobin model it was shown that a reduction in poly-molecular adsorption of heated wood is the main reason for the reduced hygroscopicity. Since good correlation between an increase in the lignin content and a reduction in the poly-molecular sorption was obtained, a reduction in the hygroscopicity of heated wood was suggested to be due to a reduction in the swelling of the wood cell wall in which micro fibrils were placed in a matrix of condensed lignin and the hemicellulose residue, rather than a reduction in the hydroxyl groups of wood. Lignin modification is thought to be the main reason for the reduced hygroscopicity.

Full textAbstract:
Metastable states are classically stable at zero temperature but can decay due to quantum tunneling. The rate of this process is exponentially small and it may be computed in Euclidean space in the Coleman-de Luccia formalism. The exponential suppression is determined by the Euclidean action computed on a trajectory with definite boundary conditions, known as Coleman-de Luccia instanton, or bounce. In some theories, the bounce may not exist or its on-shell action may be ill-defined or infinite, thus hindering the vacuum decay process. The issue of vacuum stability is, in fact, not just speculation: the Standard Model vacuum state is itself metastable. The Higgs field may tunnel outside its potential well, with catastrophic consequences for all observers. Luckily, the typical lifetime of such a state is predicted to be very long. Still, unknown high energy physics can change it by several orders of magnitude, and particle physics theories as well as cosmological models that predict large decay rates are ruled out thanks to the anthropic principle. Moreover, gravitational effects play an important role in this process, especially in the early Universe. It is thus important to examine in detail vacuum decay phenomena in gravitational settings and to keep the underlying field theory as general as possible.
This thesis aims at exploring existence conditions for the Coleman-de Luccia instanton in gravitational settings. The first two chapters are dedicated to outlining the basic formalism and describing preexisting results about vacuum decay in cosmology. The Euclidean path integral approach for decay rate calculations, which was first discussed by Callan and Coleman, is introduced in Chapter 1. A quantum mechanical description of the problem is formulated and then extended to field theory. A detailed analysis of bounce calculations and their physical interpretation as bubbles of true vacuum follows. The Higgs field stability within the Standard Model is also addressed. Gravitational effects on the vacuum decay process are considered in Chapter 2, by focusing on the decay from Minkowski and de Sitter space, as they have important cosmological consequences respectively in the current Universe (due to the smallness of the cosmological constant) and at early times. The implications on Higgs decay are discussed in both settings. The last two chapters are dedicated to new results. Vacuum decay in field theories with a scalar field and quadratic gravity is investigated. An Einstein-Hilbert term, a non-minimal coupling, and a quadratic Ricci scalar are considered while keeping the scalar field potential general. The focus is on decay from Minkowski and de Sitter space, due to their importance in cosmology. Scalar fields with Einstein-Hilbert gravity are discussed in Chapter 3, by showing that the bounce at large Euclidean radii has an analytical form that is almost entirely independent of the potential, which is called the "asymptotic bounce". Bounds on the Hubble parameter in the de Sitter case are also explored, by giving an analytical explanation to numerical evidence present in the literature. These properties are used, in Chapter 4, to test for stabilization of the false vacuum state in quadratic gravity. Conclusions follow.

Full textAbstract:
CoordenaÃÃo de AperfeÃoamento de Pessoal de NÃvel SuperiorAromatic hydrocarbons are chemical compounds of great interest in the petrochemical industry. These are commonly derived from reformed naphtha, which are in multicomponent mixtures with aliphatic hydrocarbons. The separation of these components is realized, generally, the liquid-liquid extraction process. In this process, the sulfolane is the most widely used solvent. However, this has some disadvantages such as high cost. For this reason, many studies are developed by the academic community in order to propose alternative solvents to replace the exclusive use of sulfolane by compounds that are important features like good selectivity, easy recoverability and low costs. Given the above, this study main aims to determine liquid-liquid equilibrium data (LLE) to study the ability of solvents [diethylene glycol (DEG), triethylene glycol (TEG), glycerol and 2-hydroxyethyl amine format (2-HEAF)] in extracting aromatic mixtures with aliphatic. The physical properties also of great importance in the understanding of the behavior and interactions that occur in liquid mixtures. Thus, in this study were also studied the density and viscosity of solvent extractors aromatic. The experimental methodology for the determination of LLE data was initially validated by reproducing the literature, and the results showed good agreement between these data. After the method has been validated, solubility curves and tie-lines were constructed for systems containing decane + toluene + DEG (+ TEG, + glycerol, + 2-HEAF, + sulfolane) at T = (303.15 and 333.15) K. The composition data of tie-lines, obtained experimentally, were used to calculate the selectivity parameter and the distribution coefficient. With this data, it can be concluded that all the solvents studied have a good capacity for toluene extraction from mixtures with decane. However, the glycerol has presented as the most promising solvent for aromatics extraction. Finally, the experimental data were correlated through the thermodynamic activity coefficient models, NRTL and UNIQUAC. The results were considered satisfactory, noting that the NRTL was the model that presented minor deviations in compositions. Thus, best represented the LLE data for the systems studied.
Os hidrocarbonetos aromÃticos sÃo compostos quÃmicos de grande interesse na indÃstria petroquÃmica. Estes sÃo comumente originados da nafta reformada, onde encontram-se em misturas multicomponentes com hidrocarbonetos alifÃticos. A separaÃÃo destes componentes à realizada, em sua grande maioria, pelo processo de extraÃÃo lÃquido-lÃquido. Nesse processo, o sulfolano à o solvente mais utilizado. No entanto, este apresenta algumas desvantagens, tais como alto custo. Por esse motivo, inÃmeros estudos sÃo realizados pela comunidade acadÃmica a fim de propor solventes alternativos que substituam o uso exclusivo do sulfolano por compostos que tambÃm apresentem caracterÃsticas importantes, como boa seletividade, boa recuperabilidade e baixos custos. Diante do exposto, o presente trabalho tem como principal objetivo determinar dados de equilÃbrio lÃquido-lÃquido (ELL) para estudar a capacidade dos solventes [dietilenoglicol (DEG), trietilenoglicol (TEG), glicerina e 2-hidroxietilamina formato (2-HEAF)] em extrair aromÃticos das misturas com alifÃticos. As propriedades fÃsicas tambÃm assumem extrema importÃncia no conhecimento do comportamento e das interaÃÃes que ocorrem nas misturas de lÃquidos. Deste modo, neste trabalho foram estudados a densidade e a viscosidade de solventes extratores de aromÃticos. A metodologia experimental para obtenÃÃo dos dados de ELL foi inicialmente validada reproduzindo dados da literatura, e os resultados mostraram uma boa concordÃncia entre estes dados. ApÃs a metodologia ter sido validada foram construÃdas curvas de solubilidade e tie-lines para os sistemas contendo decano + tolueno + DEG (+ TEG, + glicerina, + 2-HEAF, + sulfolano) a T = (303,15 e 333,15) K. Os dados de composiÃÃo das tie-lines, obtidos experimentalmente, foram utilizados para calcular o parÃmetro de seletividade e o coeficiente de distribuiÃÃo. De posse desses dados, pode-se concluir que todos os solventes estudados apresentam boa capacidade para extraÃÃo de tolueno a partir de misturas com decano. No entanto, a glicerina destacou-se como o solvente mais promissor para a extraÃÃo de aromÃticos apresentando os maiores valores para seletividade. Finalmente, os dados experimentais foram correlacionados atravÃs dos modelos termodinÃmicos de coeficiente de atividade, NRTL e UNIQUAC. Os resultados foram considerados satisfatÃrios, observando-se que o NRTL foi o modelo que apresentou os menores desvios na composiÃÃo. Dessa forma, representou melhor os dados de ELL para os sistemas estudados.

Full textAbstract:
SNO+ is a liquid scintillator experiment whose physics goals include measurements of solar neutrinos, reactor anti-neutrinos, geo neutrinos and double beta decay. During an initial water phase, it will also search for invisible modes of nucleon decay. This thesis investigates methods of improving the detector's sensitivity to the baryon and lepton violating processes of neutrinoless double beta decay and invisible nucleon decay. It does this through an improved scintillator model, allowing the sensitivity of the detector with different loading techniques to be evaluated, through a new background rejection technique, capable of increasing the active volume of the detector, and with the development of improved position fitters, achieving resolutions of approximately 10 cm in scintillator and 25 cm in water. The sensitivity of SNO+ to invisible modes of nucleon decay is explored, predicting, after one month of data, a limit of t > 1.38 x 1030 years on the decay of neutrons and of t > 1.57 x 1030 years on the decay of protons.

Full textAbstract:
The order $G sb{F}m sbsp{t}{2}$ electro-weak corrections to the decay $t to bW sp+$ are calculated, arising essentially from virtual radiation of the Higgs boson. For large $m sb{t}$ these represent the dominant effect serving to shift the top lifetime from its tree level value. In practice, for $m sb{t}$ $<$ 240 $GeV$ these corrections are typically 0.1%. A comparison with recent calculations of the complete electro-weak and strong effects is made.Several contributions to the branching ratio for the inclusive decay $ Upsilon to J/ psi X$ are calculated using perturbative Q.C.D. to lowest order in the relative quark momentum and the strong coupling $ alpha sb{s}$. In addition to the direct transition, decay to J/$ psi$ through the states $ psi sp prime$ and $ chi sb1$ is also considered. The following results are obtained: $Br( Upsilon to psi sp prime X$) = (0.26 $ pm$ 0.13) $ times$ 10$ sp{-3}$, $Br( Upsilon to chi sb1 X$) $ le$ 0.17 $ times$ 10$ sp{-3}$, and $Br( Upsilon to J/ psi X$) = (0.44 $ pm$ 0.15) $ times$ 10$ sp{-3}$. The latter may just be consistent with the experimental result (1.1 $ pm$ 0.4 $ pm$ 0.2) $ times$ 10$ sp{-3}$ where the first error is statistical and the second systematic.

Full textAbstract:
In single A hypernuclei, a A hyperon can occupy any orbital in the hypernucleus since it is free from the Pauli exclusion principle due to its additional quantum number strangeness. Due to the Pauli blocking effect, which suppresses the mesonic decay mode A ->N(pi) in the nuclear medium, hypernuclei larger than (5/A)He decay mainly through the nonmesonic channel, AN-> NN, where the A mass excess of 176 MeV is converted into kinetic energy of a final state of nucleons emerging above the Fermi see. This nonmesonic decay mode is assumed to proceed via the exchange of virtual mesons, and the large momentum transfer involved in the reaction leads to a mechanism that is sensitive to the short-distance behaviour of the amplitude and thus raises the possibility that the exchange of mesons heavier than the pion may play an important role. The fairly large momentum transfer also raises the hope that this reaction turns out to be insensitive to nuclear structure details and thus creates a suitable channel to investigate the weak decay mechanism.

Full textAbstract:
Most advice for improving physiological strain in the heat includes maintaining hydration using long-term acclimation protocols (>10 days). Therefore, the major aims of this thesis were to examine; (i) effectiveness of short term (5-day) heat acclimation (STHA) with moderately and highly trained athletes; (ii) fluid regulatory strain has a thermally-independent role in heat adaptation; and, (iii) impact of STHA on a marker of thermotolerancè (inducible heat shock protein 70; HSP70).
Ten moderately trained males completed heat acclimation (Acc) under controlled hyperthermia (rectal temperature 38.5�C) for 90-min on five consecutive days (T[a] = 40�C, 60% RH), on two occasions separated by a five-week washout, in a cross-over design. One Acc was undertaken with euhydration (fluid replenishment; EUH) and one with dehydration (no fluid intake; DEH) during daily Acc bouts. Participants completed an exercising heat stress test (HST) one week before, then on the 2nd day after Acc for both regimes. HST involved cycling at 40% PPO for 90 min (T[a] = 35�C, 60% RH), 10 min rest and a ramp protocol (2% PPO each 30 s) to volitional fatigue. HSTs were further completed 1, 2, and 3 wks after Acc to track the acclimation decay. On a later occasion eight highly trained male rowers were heat acclimated under the same protocol but with DEH acclimation only and a rowing-specific HST (2000 m rowing performance test). Plasma volume (PV) at rest and cardiac output (Q̇) during HSTs were measured using CO and CO₂ rebreathing, respectively. A number of plasma constituents were measured: PV, AVP, aldosterone, HSP70, total protein, albumin, Na⁺, K⁺, Cl⁻ and osmolality.
Short term heat acclimation resulted in physiological adaptation and enhanced exercise capacity for moderately trained participants. Compared to EUH permissive DEH during Acc bouts conferred larger acclimation-induced increases in resting PV by 4.1% (95%CI: -1.5 to 9.8%; p=0.06), Q̇[F]. (4.2: 0.7 to 7.8 mlmin⁻� 100 ml⁻�; p0.009), FVC (0.06: 0.02 to 0.10 ml 100ml Tissue⁻�mmHg⁻�; p=0.006), end-exercise V[s] (45.9: 3.6 to 84.4 mL; p=0.02) and decreased end-exercise f[c] by 17% (19: -29 to 9 b�min⁻�; p=0.08). Cardiovascular adaptations except PV persisted for one wk, but not two wks after Acc indicating that cardiovascular-related benefits from STHA may not be mediated by hypervolaemic responses per se. The highly trained athletes had functional heat adaptations of similar magnitude to lesser fitness-adapted participants across DEH acclimation, including resting PV expansion (4.5: 0.7 to 8.3%) and increased performance (-4.0: -6.3 to 0.6[s]; p=0.02). Plasma total protein-corrected HSP70 concentration increased from rest to end-exercise across acclimation (p=0.001). There was a greater change from rest to end-exercise on day one versus day five Acc (p=0.05), indicating a reduced stress-induced increase and a protective adaptive change. There were weak to moderate relationships between hydration indices in dynamic circumstances indicating that there is no single measure to accurately assess hydration status.
In conclusion, short-term (5-day) heat acclimation was effective with adaptations more pronounced after fluid regulatory strain from a dehydration acclimation regime. Similar findings were found using highly trained and lesser- fitness adapted participants. Thermotolerance was increased by dehydration acclimation.

The decay properties of the neutron deficient nuclei $ sp{144}$Gd, $ sp{142}$Gd, $ sp{ rm 141g}$Gd, $ sp{ rm 141m}$Gd and $ sp{140}$Gd are investigated in detail for the first time and the new beta decaying isomers $ sp{ rm 141g,m}$Gd, $ sp{141}$Tb(A) and $ sp{140}$Gd are discovered. A gas-jet recoil-transport system and a conversion electron spectrometer are designed and constructed in order to measure the electromagnetic transitions emitted following their decay. Levels schemes are deduced for the daughter nuclei $ sp{144}$Eu, $ sp{142}$Eu, $ sp{141}$Eu, $ sp{140}$Eu, and $ sp{141}$Gd and spin-parity assignments are established for several states. The decay half-life of these nuclei is also measured.The deduced information is discussed in the general context of the Z $ geq$ 50, N $ leq$ 82 mass region. The low lying structure of the N = 76, 77, 78, 79, 81 and 82 isotones is compared to the predictions of theoretical calculations using either spherical BCS or deformed Hartree-Fock plus BCS formalism with a semi-realistic interaction derived from the Tabakin potential. Contributions to original knowledge are outlined in Chapter V.

As the coldest form of matter known to exist, atomic Bose-Einstein condensates are unique forms of matter where the constituent atoms lose their individual identities, becoming absorbed into the cloud as a whole. Effectively, these gases become a single macroscopic object that inherits its properties directly from the quantum world. In this work, I describe the quantum properties of a zero temperature condensate where the atoms have a propensity to pair, thereby leading to a molecular character that coexists with the atoms. Remarkably, the addition of this molecular component is found to induce a quantum instability that manifests itself as a collective decay of the assembly as a whole. As a signature of this phenomenon, there arises a complex chemical potential in which the imaginary part quantifies a coherent decay into collective phonon excitations of a collapsing ground state. The unique decay rate dependencies on both the scattering length and the density can be experimentally tested by tuning near a Feshbach resonance. Being a purely quantum mechanical effect, there exists no mechanical picture corresponding to this coherent many-body process. The results presented can serve as a model for other systems with similar underlying physics.

Hughes, Mark Andrew. "The decay of short period comets." Thesis, University of Sheffield, 2000. http://etheses.whiterose.ac.uk/14785/.
Full textAbstract:
This thesis considers both the mass of dust released by short period comets and the size distribution of a decaying cometary population. The secular variation in the H 10 absolute magnitude of comets 2P /Encke, 4P /Paye, 6P /d'Arrest, 7P /Pons-Winnecke and lOP/Tempel 2 is investigated and it is concluded that there is more information in the H 10 data than can be found from a linear regression analysis. A computer program is presented that takes the absolute magnitude of a comet, H 10, the orbital eccentricity and the perihelion distance, and calculates the mass of dust released by the comet per apparition. This model is applied to the H1O data set for the above comets, and it is concluded that 4P /Paye has been a prolific contributor of dust to the inner Solar System, releasing an average of (21.6 ± D.5) x 1011 g per apparition during the last 19 recorded apparitions. This is mainly attributed to an unusual period of activity pre-1910. A simple model of cometary decay, whereby individual comets lose a constant depth from the cometary nucleus at each apparition is presented. This is used to model the decay of a model population of short period comets. The population is examined at regular time intervals and the mass distribution index is calculated. This index indicates how mass is distributed within the cometary population, and is found to decrease, non-linearly, as comets in the population decay. The total mass of dust released by a model population of comets, each having only one perihelion passage, is also calculated. The list of cometary orbits for this population is kept fixed and the cometary H1O values are randomly mixed up and reassigned back to the list of orbits. In this way new populations of short period comets are created. It is concluded that the current population of short period comets releases an unusually small total mass of dust, and that this is due to the average value of H10 decreasing as a function of perihelion distance.

Full textAbstract:
Micropitting is a type of surface contact fatigue often observed in gears and rolling element bearings operating under mixed or elastohydrodynamic lubrication (EHL). Once initiated, micropitting will lead to the catastrophic failure of the affected components which then requires unplanned industrial shutdowns to allow for their replacement. Micropitting in carburised gears has become a major concern in the wind power industry and other sectors where gears operate at relatively high loads and relatively slow speeds. It occurs most often in parallel axis gears (spur and helical) but it was also reported in other types of gears such as spiral bevel gears. An important feature that has been observed in bearings damaged by micropitting was the transformation of the initial microstructure. The change in microstructure, known as martensite decay, consists in the development of a new phase known as Dark Etching Region (DER) due to its appearance in reflected light microscopy. This microstructural change which has also been observed in gears leads to changes in the mechanical properties in the affected regions with implications on the initiation and propagation of the cracks leading to the formation of micropits. The fatigue life of gears can be extended by controlling the formation of micropits but this requires an in-depth understanding of the micropitting mechanism. The aim of this project was to identify and characterise the microstructural changes accompanying micropitting in gears and to develop a micropitting mechanism which describes the formation of the micropits. The microstructure has been investigated by electron microscopy techniques such as Scanning Electron Microscopy (SEM), Electron Backscattered Diffraction (EBSD), and Transmission Electron Microscopy (TEM). Nanoindentation was used to determine the mechanical properties of the affected regions. The proposed micropitting mechanism is based on the results from the above investigations as well as Density Functional Theory (DFT) calculations of material properties combined with Finite Element Analysis (FEA) of the contact region.
