Recently the unique possibility to transfer the WASA detector from TSL in Uppsala to COSY in Jülich has appeared. This transfer will be advantageous to both the current WASA collaboration at CELSIUS and the current COSY user group, since it will allow for a continued utilization of the WASA detector and it will enable a much more complete exploitation of the physics potential of COSY. This symbiosis will allow WASA to capitalize on the higher beam energy and polarized beams available and COSY to measure many of the possible final states with more than one photon. This report presents a sketch of the physics program forseen for WASA at COSY and the ongoing activities to prepare the transfer.

There exist a variety of multi-pulse NMR experiments for spectral assignment of complex molecules in solution. The conventional heteronuclear multiple-quantum coherence (HMQC) NMR experiment provides correlation between weakly coupled hetero-nuclei. The COSY is one of the most popular two-dimensional NMR experiment which is used to correlate J-coupled homo-nuclei of spectral assignment. The combination of the conventional HMQC and COSY NMR experiments yields a new experiment called 3D HMQC-COSY NMR experiment. The product operator theory is widely used for the analytical descriptions of multi-pulse NMR experiments for weakly coupled spin systems in liquids. In this study, complete product operator theory for weakly coupled IS (I = 1, S = 1) spin system is presented by obtaining the evolutions of the product operators under the spin-spin coupling Hamiltonian. As an application and a verification, analytical descriptions of 3D HMQC-COSY NMR experiment are obtained for weakly coupled ISnI’_S’m (I = I’ = 1/2; S = S’ = 1; n = 1,2, 3; m = 1, 2) multi-spin systems. Then the estimated spectra of this experiment for various multi-spin systems are explained in detail.

Gli esperimenti con bersagli polarizzati e fasci di protoni polarizzati offrono una grande opportunita` per lo studio di un numero importante di osserv- abili fisiche fondamentali. Nell’ambito di questa tesi sono presi in consider- azione esperimenti in programma presso l’anello di accumulazione COoler SYnchrotron (COSY) del Forschungszentrum Ju ̈lich (FZJ). La collaborazione PAX (Polarized Antiproton eXperiment) pianifica di re- alizzare esperimenti di produzione Drell-Yan in collisioni protone-antiprotone, entrambi polarizzati, nella struttura Facility for Antiproton and Ion Research (FAIR) di Darmstadt. Questo tipo di processo permette un accesso diretto alla struttura di spin trasverso del nucleone. Finora non `e stato possibile ` produrre fasci di antiprotoni con una polarizzazione accettabile. E obiettivo della collaborazione PAX sviluppare un metodo efficiente per polarizzare an- tiprotoni in un anello di accumulazione. La collaborazione ha svolto con suc- cesso un test di “spin-filtering” con protoni a COSY, usando un bersaglio di idrogeno polarizzato trasversalmente. Questo ha portato a determinare la sezione d’urto spin-dipendente di “build-up” ella polarizzazione trasversa, provando che lo “spin filtering” `e un metodo valido per polarizzare un fascio in un anello di accumulazione. PAX intende utilizzare il setup sperimentale unico offerto da COSY per applicare questo metodo alla polarizzazione longitudinale. In preparazione a tale test, `e stato costruito un nuovo rivelatore mediante una collaborazione tra l’Universita` di Ferrara, l’INFN di Ferrara ed il Forschungszentrum Juelich. Il nuovo rivelatore sar`a utilizzato sia per l’esperimeto di “spin-filtering” lon- gitudinale a COSY, sia per i futuri esperimenti con antiprotoni. ` E inoltre previsto l’utilizzo del nuovo rivelatore PAX per l’esecuzione di un’interazione di violazione dell’invarianza temporale (TIVOLI). Ora `e ben chiaro che la violazione dell’inversione del tempo (T-V), come l’equivalente violazione delle simmetrie combinate di carica (C) e parit`a (P) (CP-V), `e un ingrediente necessario per affrontare il mistero della l’asimmetria materia- antimateria del nostro Universo - uno dei piu` grandi problemi irrisolti nella ` fisica e nella cosmologia contemporanea. E ampiamente accettato che una soluzione di questo rompicapo comporter`a nuova fisica oltre il Modello Stan- dard (SM) della fisica delle particelle elementari (BSM). L’esperimento TIVOLI dovrebbe limitare o addirittura scoprire la fisica BSM indagando Le violazioni della simmetria a T sono complementari alle ricerche di Momenti di Dipolo Elettrico (EDM). Gli obiettivi sono (i) una ricerca di T-V diretta attraverso una precisa misurazione di diffusione elastica protone-deutone a doppia polarizzazione, sfruttando lo spin delle particelle come ”manopola per l’inversione del tempo”, e (ii) lo sviluppo di una sol- ida base teorica per l’interpretazione delle interazioni T-V, in particolare i risultati sperimentali di TIVOLI. L’ambiente sperimentale unico offerto dal sincrotrone piu` freddo (COSY) anello di stoccaggio presso il Forschungszen- trum Ju ̈lich promette Questa tesi si concentra sul lavoro svolto per la costruzione e la messa in funzione di questo nuovo rivelatore, che consiste in quattro quadranti identici disposti in una configurazione a diamante. Ognuno di questi quadranti `e for- mato da tre strati di sensori a strisce di silicio fronte-retro, che costituiscono una struttura a telescopio. I sensori dei primi due strati sono spessi 300μm, quello del terzo 1000μm.
Experiments with polarized internal gas targets and polarized proton beams give a great opportunity to access a number of fundamental physics observ- ables. In the frame of this thesis I consider experiments performed at the Cooler Synchrotron COSY storage ring at Forschungszentrum Ju ̈lich (FZJ). The PAX (Polarized Antiproton eXperiment) collaboration plans to carry out Drell-Yan production experiments in proton-antiproton collisions, both polarized, in the Facility for Antiproton and Ion Research (FAIR) facility in Darmstadt. This type of process allows direct access to the transverse spin structure of the nucleon. Until now it has not been possible to produce antiproton beams with an acceptable polarization. The objective of the PAX collaboration is to develop an efficient method to polarize antiprotons in a storage ring. The collaboration successfully performed a spin-filtering test with COSY protons, using a transversely polarized hydrogen target. This led to the determination of the spin-dependent cross-section of ”build-up” of the transverse polarization, proving that ”spin filtering” is a valid method to polarize a beam in a storage ring. PAX intends to use the unique experimental setup offered by COSY to apply this method to longitudinal polarization. In preparation for this test, a new detector (PAX detector) has been built through a collaboration between the University of Ferrara, the INFN of Ferrara and the Forschungszentrum Ju ̈lich. The new detector will be used both for the longitudinal spin-filtering experiment at COSY and for future experiments with antiprotons. There is also a plan to use the new PAX detector for performing a Time Invariance Violation Interactions (TIVOLI). Now it is well understood that time reversal violation (T-V), like the equivalent violation of the combined symmetries of charge (C) and parity (P) (CP-V), is a necessary ingredient for addressing the mystery of the matter-antimatter asymmetry of our Universe - one of the biggest unsolved problems in contemporary physics and cosmology. It is widely accepted that a solution of this puzzle will involve new physics beyond the Standard Model (SM) of elementary particle physics (BSM). TIVOLI experiment should constrain or even discover BSM physics by investigating T-symmetry violations complementary to searches for Elec- tric Dipole Moments (EDM). The objectives are (i) a search for direct T-V through a precise measurement of double polarized proton-deuteron elastic scattering, exploiting the particle spin as a “time reversal knob”, and (ii) the development of a solid theoretical basis for the interpretation of T-V interactions, in particular the experimental findings of TIVOLI. The unique experimental environment offered by the cooler synchrotron (COSY) stor- age ring at Forschungszentrum Ju ̈lich promises to improve the present upper limit on T-V by one to two orders of magnitude, using COSY as a zero degree spectrometer and PAX detector. This thesis focuses on the work done for the construction and commis- sioning of the new PAX detector, which consists of four identical quadrants arranged in a diamond configuration. Each of these quadrants consists of three layers of double-sided silicon striped sensors, which form a telescope structure. The sensors of the first two layers are 300μm thick and the third layer is 1000μm thick. A first detector test, with two of the four quadrants installed opposite to each other, was successfully conducted at COSY using a beam of un- polarized protons and a target of vector-polarized deuterons. By operating the detector in the described configuration, an energy resolution 60 keV, was achieved for the first two layers of detectors. The spatial resolution is in the order of σ ≈ 200μm. The results of the test are illustrated in this thesis.

A literatura específica da área de Ensino de Ciências tem apresentado importantes discussões sobre dificuldades de aprendizagem e compreensão de conceitos científicos pelos alunos. Diante disso, já há algum tempo a História da Ciência tem sido defendida enquanto elemento que pode auxiliar no processo de ensino-aprendizagem dos conceitos científicos. Apesar do potencial educacional que é atribuído à História da Ciência e do esforço que tem sido feito para aproximá-la da educação científica, existem algumas barreiras que podem inviabilizar o sucesso desta aproximação impedindo que ela cumpra, efetivamente, o seu papel frente ao Ensino de Ciências. Dentre as barreiras que a literatura aponta, destacamos a falta de material histórico de qualidades e acessível a alunos e professores que possa subsidiar práticas metodológicas em sala de aula. No bojo dessa escassez está a falta de traduções de fontes primárias para o português. Tendo em vista tal contexto, este trabalho de doutorado tem como objetivo geral de fazer a tradução comentada dos dez artigos de Stephen Gray (1666-1736) relacionados à eletricidade. Dos dez textos traduzidos, nove foram publicados no periódico Philosophical Transactions of the Royal Society e uma carta foi publicada por Chipman (1954). Como objetivo específico propomos elaborar um conjunto de elementos, os quais denominamos de recursos didáticos, que possam ampliar o acesso de professores e alunos ao conteúdo das traduções: comentários em forma de notas; figuras; experimentos históricos com material de baixo custo; breve biografia do autor do texto traduzido; linha do tempo do período em questão; introdução geral ao texto. Stephen Gray foi um importante, porém mencionado, pesquisador do início do Século XVIII. Seu trabalho trouxe importantes...
The specific literature related to Science Education has presented important discussion on the difficulties faced by students in the learning and understanging of scientific concepts. In this context, some time ago the History of Science has been advocated as an element that can facilitate the process of teaching scientific conceps. Despite the educational potential that is assigned to the History of Science and the effort that has been done to bring it closer to Science Education, there are some barriers that can hinder the sucess of this approach, preventing it to fulfill effectively its role with the teaching of science. Among the barriers pointed out by the literature, we emphasize the lack of historical material with quality and accessible to students and teachers that can subsidize methodological practices in the classroom. Among this shortage of historical material, there is a lack of Portuguese translations of primary sources. Given this context, the main goal of this PhD work is the translation into Portuguese of the ten articles of Stephen Gray (1666-1736) related to electricity. Of the ten translated texts, nine were published in the Philosophical Transactions of the Royal Society and a letter was published by Chipman (1954). The specific goal of this thesis is to prepare a set of elements, which we will call teaching resources, that can expand the accesss of the content of the translations to teachers and students: comments as notes; figures; historical experiments with law-cost material; brief biography of the author of the tranlated text; timeline of the period; and a general introduction to the text. Stephen Gray was an important, though rarely mentioned, researcher at the beginning of the Eighteenth Century. His work has brought important contributions to the field of electricity. Some of his...

Functional response experiments are commonly used to explore predator-prey systems, where we are interested in learning about the number of prey consumed per predator as a function of prey density. Currently, functional response experiments are designed in an ad-hoc manner and may require significant experimentation to learn about the underlying system. In this thesis, we developed statistically principled functional response designs to learn about the true mathematical model driving the predator-prey dynamics as quickly as possible. This can lead to functional response experiments with reduced monetary costs and less sacrificing of animals.

In einer systematischen Analyse wird die Produktion von ω-Mesonen in Proton-Proton-Kollisionen pp → ppω untersucht. Die Messung der experimentellen Daten wurde mit dem Flugzeitspektrometer COSY-TOF am Forschungszentrum Jülich für vier verschiedene Überschussenergien (ε = 92, 128, 129 und 173 MeV, ε = √s − 2 · mp − mω) durchgeführt. In der Analyse werden Ereignisse, in denen das kurzlebige ω-Meson über den Hauptzerfallskanal ω → π+π−π0 in drei Pionen zerfällt, gegenüber denen anderer Reaktionskanäle angereichert. Die Reaktion pp → ppω wird anschließend anhand der Signale in den Spektren der Missing Mass, das ist die im Ausgangskanal neben der invarianten Masse des Proton-Proton-Systems fehlenden Masse, untersucht. Totale sowie differentielle Wirkungsquerschnitte werden in verschiedenen Bezugssystemen bestimmt, u. a. die Winkelverteilungen der Protonen und ω-Mesonen im Schwerpunktsystem, Verteilungen von Jackson- und Helizitätswinkeln sowie die Spektren der invarianten Massen. Darüber hinaus wird mit Hilfe der Bestimmung der Zerfallsebenen der ω-Mesonen die Polarisation der ω-Mesonen ermittelt. Im Dreiteilchenausgangszustand ppω werden Bahndrehimpulse l > 0 nur für die ω-Mesonen gefunden. Aus der Messung folgt, dass bei ε = 92, 128 und 129 MeV maßgeblich Endzustände mit Bahndrehimpulsen lω = 0 ħ und lω = 1 ħ sowie bei ε = 173 MeV zusätzlich solche mit lω = 2 ħ zum Reaktionsprozess beitragen. Weitere Informationen über die beteiligten Partialwellen werden aus der Messung der Polarisation der ω-Mesonen gewonnen. Direkte Hinweise auf Beiträge von Nukleonresonanzen zum Produktionsprozess werden in keiner der untersuchten Observablen gefunden. Ein Szenario, in dem ω-Mesonen ausschließlich über Nukleonresonanzen produziert werden, kann anhand der Winkelverteilungen von Protonen und ω-Mesonen ausgeschlossen werden
A systematic analysis of the production of ω mesons in proton-proton collisions pp → ppω is carried out. The experimental data were taken at Forschungszentrum Jülich with the COSY-TOF spectrometer at four different excess energies (ε = 92, 128, 129 and 173 MeV, ε = √s − 2 · mp − mω). In the analysis events with ω-mesons decaying via the main decay channel ω → π+π−π0 are enriched in relation to other reaction channels. Afterwards, the reaction pp → ppω is analysed based on the ω-signals in the spectra of the missing mass, i. e. the mass missing in the exit channel beside the proton-proton system. Total as well as differential cross sections are determined in different reference systems (angular distributions of ω-mesons and protons in CMS, distributions of Jackson and helicity angles, and invariant mass spectra). In addition the polarisation of the ω-mesons is determined. In the three particle exit channel ppω angular momenta l > 0 are seen only for ω-mesons. It is found that final states with angular momenta lω = 0 ħ and lω = 1 ħ contribute at excess energies ε = 92, 128 and 129 MeV. In addition states with lω = 2 ħ are seen at ε = 173MeV. Further informations on partial waves follows for the polarisation of the ω-meson. No observable shows direct signs of resonant contributions to the production process. In contrast, using the informations from the angular distributions of ω-mesons and protons a scenario with the exclusive production of ω-mesons through N* resonances can be excluded

This dissertation addresses the problem of Computer Aided Architectural Evaluation and Design, with particular reference to building cost evaluation and cost modelling. It identifies the lack of building evaluation tools in the CAAD environment, and suggests an integrated approach to building modelling and cost modelling. The interaction of elemental and spatial descriptions of a design solution is considered as an original contribution to the field of computer aided building modelling and evaluation. It demonstrates the potential of CAAD and Bills of Quantities intergration to give an extra dimension to cost modelling at early design stages. Essentially, this research project advocates a larger overlap in the use of computers for the generation and evaluation of design. It asserts that any computer aided solution evaluation system must be able to converse with the designer during the highly integrated iteration of briefing, analysis, synthesis and evaluation stages of design. A working example is produced after software specification and implementation, to demonstrate to possibilities and/or limitations of such an approach.

AbstractNowadays, generating omics data is a common activity for laboratories in biology. Experimental protocols to prepare biological samples are well described, and technical platforms to generate omics data from these samples are available in most research institutes. Furthermore, manufacturers constantly propose technical improvements, simultaneously decreasing the cost of experiments and increasing the amount of omics data obtained in a single experiment. In this context, biologists are facing the challenge of dealing with large omics datasets, also called “big data” or “data deluge.” Working with omics data raises issues usually handled by computer scientists, and thus cooperation between biologists and computer scientists has become essential to efficiently study cellular mechanisms in their entirety, as omics data promise. In this chapter, we define omics data, explain how they are produced, and, finally, present some of their applications in fundamental and medical research.

AbstractRenal tissue hypoperfusion and hypoxia are early key elements in the pathophysiology of acute kidney injury of various origins, and may also promote progression from acute injury to chronic kidney disease. Here we describe methods to study control of renal hemodynamics and tissue oxygenation by means of invasive probes in anesthetized rats. Step-by-step protocols are provided for two setups, one for experiments in laboratories for integrative physiology and the other for experiments within small-animal magnetic resonance scanners.This publication is based upon work from the COST Action PARENCHIMA, a community-driven network funded by the European Cooperation in Science and Technology (COST) program of the European Union, which aims to improve the reproducibility and standardization of renal MRI biomarkers. This experimental protocol chapter is complemented by a separate chapter describing the basic concepts of quantitatively assessing renal perfusion and oxygenation with invasive probes.

AbstractFluorine-19 MRI shows great promise for a wide range of applications including renal imaging, yet the typically low signal-to-noise ratios and sparse signal distribution necessitate a thorough data preparation.This chapter describes a general data preparation workflow for fluorine MRI experiments. The main processing steps are: (1) estimation of noise level, (2) correction of noise-induced bias and (3) background subtraction. The protocol is supplemented by an example script and toolbox available online.This chapter is based upon work from the COST Action PARENCHIMA, a community-driven network funded by the European Cooperation in Science and Technology (COST) program of the European Union, which aims to improve the reproducibility and standardization of renal MRI biomarkers. This analysis protocol chapter is complemented by two separate chapters describing the basic concept and experimental procedure.

The solution to many engineering problems is obtained through the combination of analytical, computational and experimental methods. In many cases, cost or size constraints limit testing of full-scale articles. Similitude allows observations made in the laboratory to be used to extrapolate the behavior to full-scale system by establishing relationships between the results obtained in a scaled experiment and those anticipated for the full-scale prototype. This paper describes the application of the Buckingham Pi theorem to develop a set of non-dimensional parameters that are appropriate for describing the problem of a distributed load applied to the rostrum of the paddlefish. This problem is of interest because previous research has demonstrated that the rostrum is a very efficient structural system. The ultimate goal is to estimate the response of a complex, bio-inspired structure based on the rostrum to blast load. The derived similitude laws are verified through a series of numerical experiments having a maximum error of 3.39%.

We exploit new experimental and quasi-experimental data to investigate voters' intrinsic motivation to engage politically. Does having the right to vote increase engagement or, given significant incentives to free ride, do eligible voters remain rationally unengaged? Does knowledge that ones group is pivotal reduce free riding? And are the politically engaged influenced by election-relevant policy information in the run-up to a major election? To address these questions, we fielded an original survey of 5,400 Mexican high school seniors just prior to the historic 2018 general election. Age-based regression discontinuity results show that the just-eligible score higher on measures of low-cost political engagement compared to the just-ineligible. A first survey experiment reveals that information that the youth vote will be pivotal increases the eligible respondents' interest in the presidential debate and in the election result. In the second experiment, information about current policy outcomes affects future policy priorities in ways consistent with the incentives of eligible respondents to collect relevant information on salient policy issues.

Empirical results in economics often stem from success in controlled experimental settings, but often fail when scaled up. This study presents a behavioral intervention and a scalable equivalent aimed at reducing teacher shortages by motivating high school students to pursue an education degree. The intervention was delivered through WhatsApp chats by trained human promoters (humans arm) and rule-based Chatbots programmed to closely replicate the humans program (bots arm). Results show that the humans arm successfully increased high-school students demand for and enrollment in education majors, particularly among high-performing students. The bots arm showed positive but smaller and statistically insignificant effects. These findings indicate that a relatively low-cost intervention can effectively reduce teacher shortages, but scaling up such interventions may have limitations. Therefore,testing scalable solutions during the design stage of experiments is crucial.

Air pollution is one of the primary causes of premature death worldwide. This paper examines the cost-effectiveness of two different air quality information programs that were implemented as part of randomized control trials. In the case of the SMS air quality alerts in Mexico City, we find that the program was not cost-effective in the experimental sample, but it would likely be cost-effective if the program were extended to all of Mexico City. In the case of real-time feedback on wood stove emissions in Valdivia, we find that the program was cost-effective in both the experimental sample and at scale.

This report summarizes the test results of a joint horizontal gas storage well field experiment undertaken at the West Edmond Storage field in Oklahoma. An existing vertical well with 7-in. casing set through the Red Fork sand was plugged and horizontally extended over 1500 feet in 32 days. On test, the horizontal well produced at an initial rate of over six times the vertical well. Cost was less than twice the cost of the vertical well. Thus, this experiment successfully demonstrated the technical and economic viability of implementing horizontal well technology to increase deliverability in gas storage fields. A comprehensive implementation plan, developed as a part of this field experiment, is also described in this report. This step-by-step approach is designed to enable gas storage operators to ensure a high degree of success in implementing horizontal well technology in their fields.

House flies (Muscadomestica) are global pests of animal agriculture, causing major annoyance, carrying pathogens among production facilities and humans and thus have profound impacts on animal comfort and productivity. Successful fly control requires an integrated pest management (IPM) approach that includes elements of manure management, mass trapping, biological control, and selective insecticide use. Insecticidal control of house flies has become increasingly difficult due to the rapidity with which resistance develops, even to new active ingredients. Global climate change poses additional challenges, as the efficacy of natural enemies is uncertain under the higher temperatures that are predicted to become more commonplace in the future. The two major objectives of this research project were: 1) to develop a cost-effective autodissemination application method of Pyriproxifen (PPF), an insect growth regulator, for controlling house flies; 2) to study the effect of increasing temperatures on the interactions between house flies and their principal natural enemies. First, we collected several wild house fly populations in both countries and established that most of them are susceptible to PPF, although one population in each country showed initial signs of PPF-resistance. An important finding is that the efficacy of PPF is substantially reduced when applied in cows’ manure. We also found that PPF is compatible with several common species of parasitoids that attack the house fly, thus PPF can be used in IPM programs. Next, we tried to develop “baited stations” in which house flies will collect PPF on their bodies and then deliver and deposit it in their oviposition sites (= autodissemination). The concept showed potential in lab experiments and in outdoor cages trials, but under field conditions the station models we tested were not effective enough. We thus tested a somewhat different approach – to actively release a small proportion of PPF-treated flies. This approach showed positive results in laboratory experiments and awaits further field experiments. On the second topic, we performed two experimental sets: 1) we collected house flies and their parasitoids from hot temperature and mild temperature areas in both countries and, by measuring some fitness parameters we tested whether the ones collected from hot areas are better adapted to BARD Report - Project 4701 Page 2 of 16 heat. The results showed very little differences between the populations, both of flies and parasitoids. 2) A “fast evolution” experiment, in which we reared house flies for 20 generations under increasing temperatures. Also here, we found no evidence for heat adaptation. In summary, pyriproxyfen proved to be a highly effective insect growth regulator for house flies that is compatible with it’s natural enemies. Although our autodissemination stations yielded disappointing results, we documented the proportion of flies in a population that must be exposed to PPF to achieve effective fly control. Both the flies and their principal parasitoids show no evidence for local adaptation to high temperatures. This is an encouraging finding for biological control, as our hypothesis was that the fly would be adapting faster to high temperatures than the parasitoids. BARD Report - Project 4701 Page 3 of 16
