KONONOV, Anton. "Multipurpose silicon detector for (polarized) internal target experiments at the COSY Storage Ring in Jülich." Doctoral thesis, Università degli studi di Ferrara, 2020. http://hdl.handle.net/11392/2488096.
Повний текст джерелаExperiments 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.

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...

Повний текст джерелаA 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

Este trabalho de dissertação, do Programa de Pós-graduação em Ensino de Ciências Naturais (PPGECN) promovido pela Universidade Federal de Mato Grosso (UFMT), utiliza montagens experimentais com materiais de baixo custo e simulações de computador para auxiliar na compreensão de conceitos de Física pelo aprendiz. Essa metodologia foi aplicada no Instituto Federal de Educação, Ciência e Tecnologia de Rondônia - IFRO/campus Jiparaná, com os alunos dos cursos de Informática e Química integrados ao ensino médio, minicurso de capacitação para os professores de Ciências Naturais da E.E.E.F.M Aluizio Ferreira, Ji-paraná/RO e apresentação dos mecanismos de manuseio do software e os protótipos para os professores de Física do IFRO. Trata de conciliar a prática educativa com as confecções de protótipos e seus respectivos simuladores no software PhET (Physics Education Technology). A execução da atividade em sala de aula se deu por meio da divisão em grupos das turmas. Cada grupo registrou todo o processo de montagem dos protótipos em um relatório, comentando suas experiências de trabalho em grupo e os novos conceitos encontrados ao explorar o experimento e o simulador. No minicurso com os professores, foram apresentados todos os experimentos confeccionados e tutoriais dos simuladores e dos protótipos e suas respectivas simulações, propondo a eles um plano de execução. Essa proposta traz vantagens aos professores que utilizam as simulações nas aulas de Física. A utilização equilibrada dos recursos experimentais e computacionais fornece um apoio ao professor em suas demonstrações de conceitos relacionados ao assunto em questão, que podem ser de difícil visualização para os alunos.
This dissertation work, of the Program Postgraduate in Teaching of Natural Sciences (PPGECN) held by the Federal University of Mato Grosso (UFMT), uses experimental apparatus with low cost materials and computer simulations to aid in the understanding of physics concepts by the student. This methodology was applied at Federal Institute of Education, Science and Technology of Rondônia - IFRO / Campus Ji-paraná, with students of the technical course of Informatics and Chemistry and in a training course for Natural Sciences teachers of EEEFM Aluizio Ferreira, Ji-Paraná/RO and presentation mechanisms for handling software and prototypes for teachers of Physics IFRO. This work aimed to reconcile educational practice with the development of prototypes and their software simulators in PhET (Physics Education Technology). The execution of the activity in the classroom was given by dividing the class into groups. Each group made a register of the assembly process of the prototypes in a report commenting on their experiences of working in groups and the new concepts encountered exploring the experiment and the simulator. All the prepared experiments, tutorials simulators, prototypes and their respective simulations were presented, proposing an implementation plan at a short course made with teachers. This proposal brings benefits to teachers that can use simulations in physics classes. The utilization of experimental and computational resources aid the teacher to explain concepts that otherwise could be difficult for students to understand.

Повний текст джерелаAs the Navy has refocused its goals towards littoral warfare, mine countermeasures have become an area of special interest. The Naval Postgraduate School is developing an autonomous underwater vehicle to map shallow water minefields--a vital role in the Navy's overall plan for mine countermeasures. A key feature of the vehicle is its low cost, and to this end it uses a commercially available system called 'DiveTracker' for precise acoustic navigation and communication. This research experimentally evaluated the reliability of the DiveTracker communication system in conditions approximating those for which the vehicle is designed. It was concluded that highly reliable communication of short commands will be restricted to relatively short separation distances between nodes. The very shallow water acoustic channel is highly variant in both signal attenuation and background noise levels. The maximum range is limited by the background noise while the probability of correct message reception depends on the received signal to noise ratio. Initial data indicates that the low cost unit under development cannot communicate beyond 500 meters with a probability of a single roundtrip success greater than 34 percent. Several options are available for its improvement.

Повний текст джерелаSyftet för detta projekt är att undersöka tillverkningskostnaden, med tonvikt på bearbetning av högpresterande flänsar för turbinapplikationer (TRS), samt dess relation till strukturella prestanda och vikt. Traditionella kostnadsmodelleringstekniker kombineras med det ickekonventionella tillverkningskomplexitetsindexet och används som kostnadsindikator. En tvärvetenskaplig studie genomförs med hjälp av ANSYS Workbench i form av dator simulerade experiment för att undersöka flänsavvägningar. En slutsats av studien är att multidisciplinära modeller av kostnad, prestanda och vikt saknade robusthet för att kunna dra djupgående slutsatser om prestandan för en flänsdesign. Tillverkningskomplexitetsindexet visar dock, efter partiell validering med erfarna ingenjörer, lovande resultat och kan vara framgångsrikt ett sätt att uppskatta den slutliga bearbetningskostnaden för flänsar.

Повний текст джерелаThe increasing demand for analytical platforms that are reliable and, at the same time, easy to use and compact, that require low sample consumption and provide high sensitivity and real-time response, have provided considerable innovation in the design of the biosensors. Among all of them, those based on surface plasmon resonance phenomena (SPR) have been the subject of great scientific interest in recent decades because they provide high sensitivity and simplicity in the detection schemes. With the advance in nanofabrication techniques, the development of optical sensors based on plasmonic nanostructures has represented an excellent way to integrate them into Lab-on-a-chip devices with a small size, with the ability to solve some of the current challenges related to the analysis times, the volume of sample required and the feasibility of detecting several analytes at the same time multiplexed. With the purpose of offering simple and inexpensive biosensing tools, this Doctoral Thesis presents the development of nanoplasmonic biosensors integrated in Lab-on-a-Chip (LOC) platforms for the multiplexed biosensing of different analytes in real time. The developed sensor is based on the use of commercial Blu-Ray discs as a substrate containing nano-slits to generate the plasmon resonance phenomena by coating them with different metallic layers on a nanometric scale. The developed nanobiosensors are a very promising alternative that could replace conventional analysis techniques, simplifying processes and overcoming the main current challenges related to sensitivity, cost and time required for clinical diagnosis.

Повний текст джерелаThe ejectors are devices widely used in the most several branches of the engineering. This work was developed at the Laboratory of Hydraulics of the School of Engineering of São Carlos - SP, with the purpose of evaluating experimentally and theoretically the acting of low cost ejectors, projected and built in connections of the type \"tee\" of PVC, where water was used as much primary fluid as secondary. The experiments were accomplished with ejectors of nominal diameters of 25 mm and of 32 mm with area ratio of 0,25; 0,35 and 0,53. It was also used, for each diameter, a more compact ejector and without mixing chamber, with the area ratio of intermediate value. The common ejectors presented higher efficiencies than the compact ones, being the maximum of 30,52% reached with the ejector of 25 mm and area ratio of 0,35. The coefficients of head loss in each component of the ejectors were adjusted through one-dimensional model. The phenomenon of the cavitation was also analyzed. The results showed that the low cost ejectors present similar operation to the conventional ejectors.

The quality of a product to a large extent determines the success of that product in competitive markets. Measuring and improving quality is thus a primary objective of the designer. The aim of the following work is to provide an introduction to the methods of quality optimization and to illustrate these techniques through examples. Quality is first defined and quantified. The robust design method, which is a technique that focuses on improving quality without adding cost, is then described. Particular attention is paid to experiment design, which is a major factor in the effectiveness and efficiency of the robust design process. The effect of product variability on the mean performance of a product is also explained along with the various ways that can be used to predict a shift in the mean value of the performance. Two examples are then developed. The first focuses on the application of the robust design method to illustrate the steps of the process. The second example primarily focuses on creating a comparison of the Monte Carlo, Latin Hypercube, and star pattern sampling methods on predicting mean shift. The benefits of the star pattern sampling method are apparent through the example. The error in the prediction of mean shift of the star pattern is less than 1%, and the execution time was less than one fifth the times of the Monte Carlo and Latin Hypercube methods.

Повний текст джерелаENGLISH ABSTRACT: Vacuum assisted resin transfer moulding (VARTM) belongs to the category of resin infusion techniques that use lower than atmospheric pressure to infiltrate a reinforced cavity. This technique has various advantages; however, manufacturing costs can be relatively high due to more difficult shapes fabricated and a lack of knowledge regarding cost driving factors. The objective of this study was to develop a cost model for composite parts. Such a model allows the estimation of manufacturing costs of shapes of different geometries. Therefore, it provides a comparison to alternative manufacturing techniques, such as metal forming or composite spray lay-up and helps to avoid unnecessarily expensive design features. The proposal was made to split complex shaped composite parts into individual basic shapes, which are further investigated here. For the basic shapes, an experimental approach was used where the manufacturing times of each process step are measured and then statistically analysed. Infusion simulation software was used to obtain additional filling times to complete the design of experiments. This method allows the estimation of manufacturing times of composite parts with different geometries. The manufacturing times were validated to that of a complex shaped industrial part, with reasonable results. Finally, a flexible cost model was developed to compare different manufacturing techniques and to estimate the manufacturing costs.
AFRIKAANSE OPSOMMING: Vakuumgesteunde harsinspuitingsgietwerk (VARTM) behoort tot die kategorie harsinspuitingstegnieke wat laer-as-atmosferiese druk gebruik om ʼn versterkte holte binne te dring. Hierdie tegniek hou verskeie voordele in. Tog kan vervaardigingskoste betreklik hoog wees wanneer dit by ingewikkelder vorms en ʼn gebrek aan kennis met betrekking tot kostesnellers kom. Die doelwit van hierdie studie was om ʼn kostemodel vir saamgestelde onderdele te ontwikkel. Die model maak voorsiening vir die raming van die vervaardigingskoste vir verskillende afmetings. Sodoende bied dit ʼn vergelyking met alternatiewe tegnieke, en help voorkom onnodig duur ontwerpkenmerke. Daar is voorgestel dat dele met ingewikkelde vorms in individuele basiese vorms verdeel word, wat dan hier verder ondersoek word. Vir die basiese vorms word ʼn eksperimentele benadering gebruik waar die vervaardigingstye in elke prosesstap gemeet en statisties ontleed word. Voorts word inspuitingsimulasiesagteware gebruik om komplementêre inspuitingstye te bepaal ten einde die eksperimentele ontwerp te voltooi.

Повний текст джерелаActualmente el diagnóstico de Tuberculosis (TB) se realiza en laboratorios centralizados, empleando equipos voluminosos, reactivos complejos y personal capacitado, aumentando los costes y el tiempo para obtener los resultados. Por esta razón, el objetivo de esta Tesis Doctoral es el desarrollo de una plataforma point-of-care (POC) capaz de ofrecer una respuesta rápida y fiable en el diagnóstico de TB. Para llevar a cabo este objetivo, la plataforma POC integra un novedoso sensor fotónico incorporado en un cartucho de micofluídica desechable. El sensor fotónico consiste en un conjunto de interferómetros Mach-Zehnder que ofrecen una alta sensibilidad. En primer lugar, se llevó a cabo una caracterización óptica para estudiar el rendimiento de la plataforma POC y su capacidad para ser empleada en aplicaciones biosensoras. Una vez caracterizada ópticamente, se evaluaron distintas estrategias de biofuncionalización para incorporar anticuerpos específicos como bioreceptores a la superficie del sensor. Después de un estudio en profundidad, se seleccionó y empleó la estrategia de biofuncionalización óptima para el análisis de los biomarcadores de TB. Los biomarcadores de TB se evaluaron tanto en solución tampón como en muestras biológicas, particularmente en orina humana. El biomarcador más prometedor y conocido de TB es el lipoarabinomanano (LAM), un componente de la pared celular bacteriana. En concreto, la detección de este biomarcador fue validada con muestras clínicas de pacientes con TB y donantes sanos, mostrando la capacidad de nuestra plataforma POC para discriminar a aquellos pacientes con Tuberculosis activa. Además, el diseño del sensor fotónico permite la detección simultánea de seis biomarcadores distintos. Teniendo esto en cuenta, hemos llevado a cabo una prueba de concepto del empleo de la plataforma biosensora POC para la detección de un panel de biomarcadores de TB utilizando nanolitografía Dip-Pen para la deposición de cada bioreceptor en cada sensor. Nuestros resultados, validados en estudios clínicos más amplios, podrían tener importantes implicaciones diagnósticas. Además, nuestro biosensor POC ofrece una serie de ventajas en comparación con los métodos recomendados por la Organización Mundial de la Salud.
Nowadays, Tuberculosis (TB) diagnosis is carried out at centralised laboratories, employing bulky equipment, complex reagents, and trained staff, increasing costs and the time to obtain the results. For that reason, the aim of this Doctoral Thesis is to develop a point-of-care (POC) platform able to deliver a prompt and reliable response to TB diagnosis, taking advantage of a highly sensitive evanescent wave optical sensor. The POC platform integrates a novel photonic sensor consisting of a Mach-Zehnder Interferometer transducer array incorporated in a disposable microfluidic cartridge. Firstly, an optical characterisation was carried out to study the new POC performance and its ability to be employed for biosensing applications. Once the POC platform was optically characterised, diverse biofunctionalisation strategies were tested in order to incorporate specific antibodies as bioreceptors to the sensor surface. After an in-depth study, the optimal biofunctionalisation strategy was selected and employed for the analysis of the TB biomarkers. The TB biomarkers were evaluated in both buffer and biological samples, particularly human urine. The most promising and well-known TB biomarker was lipoarabinomannan (LAM), a bacterial cell wall component. In particular, this biomarker detection was validated with clinical samples from TB patients and healthy donors, showing the ability of our POC platform to discriminate those patients with active TB. Moreover, taking advantage of the photonic sensor design, which allows the simultaneous detection of six different biomarkers, we initiated the proof-of-concept of the POC platform for a TB biomarker panel detection using Dip-Pen Nanolithography for each corresponding bioreceptor deposition. Our results, if validated with larger clinical studies, could have important diagnostic implications taking into account the advantages added by our POC biosensor in comparison with the methods recommended by the World Health Organisation.

Повний текст джерелаThe present study investigated the effect of a history of cooperation on the choice of a participant in cooperating or working individually, in the presence and absence of costs. Participants worked on one computer in a two-person task, with the computer simulating the performance of the second participant. At each try, each participant should choose between a blue and a green card and the combination of choices defined equal or unequal gains for participants. Due to gains, a cooperative response was defined as the participant choosing the blue card, an individual response was defined as the participant choosing the green card. This was because the use of the blue card enabled one of the participants to earn more against an array of smaller but equal gains. Participants were exposed to five phases: Fairness Phase, Favorable Iniquity Phase without Costs, Unfavorable Iniquity Phase without Costs, Favorable Iniquity Phase with Costs and Unfavorable Iniquity Phase without Costs. The computer chose the blue card in all rounds and phases of the study and the choice of the green card produced 20 points for the Participant and the computer in all phases of the study. In the Fairness Phase (10 rounds) the choice for the blue card produced 100 points for the participant and for the computer. In the Favorable Iniquity Phase without Costs (16 rounds) the choice for the blue card produced 100 points for the participant and 20 points for the computer. In the Unfavorable Iniquity Phase without Costs (16 or 32 rounds) the choice for the blue card produced 20 points for the participant and 100 points for the computer. In Favorable Iniquity Phase with Costs (16 rounds) the choice for the blue card produced 100 points for the participant and 10 points for the computer. In the Unfavorable Iniquity Phase with Costs (16 or 32 rounds) the choice for the blue card produced 10 points for the participant and 100 points for the computer. Participants were divided into two groups, which differed in the order in which they were exposed to cost. In both groups, the last phase of the study had twice as many rounds as the rest of the study. The results indicate that the effect of cost varied between participants and also depended on the order in which it was introduced: the earlier the cost was introduced, the greater the effect was to decrease the choice by the blue card (cooperate). The results also show clear signs of aversion to favorable and unfavorable iniquity. Some participants consistently produce unfavorable iniquity, which challenges formal models of aversion to iniquity

Повний текст джерелаPrematurity represent today a more and more increasing problem for public health. The aim of researching this field is to detect as early as possible altogether subjects highly prone to risk and subjects associated with selective weaknesses (which occasionally can be supported with essential actions), and subjects who are likely to be able to build up an appropriate outcome (in order to avoid useless recurrent checkups). Continuous advances in obstetric techniques and intensive e neonatal care increase the share of children surviving preterm birth without serious cerebral damages, however the most promising strategy available to compensate their weaknesses and to promote their growth potential seems to be to act to their environment, setting up for them an early intervention. Definition of a protocol of Early Intervention and planning of a trial study to evaluate his feasibility, applicability and efficacy. This is a single-blind randomized study (data analyzer were blind), that involved 42 high risk preterm babies and their mothers divided in two groups of equal size and recruited randomly (each baby have been pre assigned to one of the groups, according to birth order). Inclusion criteria for the study: gestational age ≤32 weeks and/or birth weight ≤1500 g; mothers with a good knowledge of spoken and written Italian; written informed consent. For both groups are planned four check-points: at recruiting, at hospital discharge, at 40 weeks of gestational age, at 3 months of correct age. For babies: at each check-point were done Neurological examination, General Movements videotaping, Behavioural examination by the neurodevelopmental therapist, and at hospital discharge and 40 weeks of GA also to Neonatal Intensive Care Unit Network Neurobehavioral Scale (NNNS) Attention (Orientation) subscale, Sensory-motor scale for the neonate and Global Ratings of Mother Infant Interaction Scale (GRS). For mothers: at recruiting was proposed a daily diary to note the presence in NICU/duration/kangaroo therapy (SCENE); at hospital discharge were discussed some “care” suggestions from the neurodevelopmental therapist, and delivery of an information booklets regarding characteristics and development of preterm babies. It has also be proposed PSS-NICU, the EPDS, the MSPSS, the NPST; at 40 weeks of gestational age has been proposed the MPAS and the PSI; at 3 months of correct age the Life events form, the PSI, the EPSD, the MSPSS. Only for the experimental group (Early Intervention Protocol): from recruiting to hospital discharge were proposed 2 meetings with a small group of mothers, a paediatric neuropsychiatrist and a neurodevelopmental therapist to describe some typical characteristic of preterm babies, some special needs in care habits and to talk about prematurity; from recruiting to hospital discharge 3 individual meetings with each mother and the neurodevelopmental therapist at baby’s cradle to observe together that single baby; at 40 weeks and at 3 months of correct age one individual meeting with each mother, the paediatric neuropsychiatrist and the neurodevelopmental therapist, was carried out to evaluate the changes in the baby and in the mother’s attitude. Statistical analysis (descriptive statistic, T test, K analysis, Factorial analysis, Cronbach's alpha coefficient, Pearson’s correlation coefficient, ANOVA) of results.

Повний текст джерелаdetection of structural damages. Throughout its service life, a civil structure besides the exposure to operational and environmental forces can be subjected episodically to earthquakes. These events may have a deep impact on building safety and a continuous monitoring of the structure health conditions becomes desirable or necessary in many cases. Structural Health Monitoring (SHM) provides a valuable knowledge of the dynamic behavior of monitored structures of their response to service environmental loadings, and of rise and distribution of the deterioration conditions. These techniques are widely employed in mechanical, aeronautical, and civil engineering, generally rely on vibration response measurements. The development of low cost and low energy measuring devices, the new generation of data acquisition systems, together with the increasing availability of software for advanced dynamic analysis, have extended SHM to several areas where up to now the high cost of traditional equipment was not justified by the value of structure itself. In civil engineering, SHM is moving from big infrastructures like bridges, dams and skyscrapers to historical heritage and residential buildings. Within this a background, the purpose of this work is to propose a new combined experimental and numerical methodology to perform the SHM of civil structures lying in seismic hazard zones. A relatively low-cost SHM prototype system based on this approach has been developed and the issues related to the usage of low-cost sensors and new generation data acquisition tools for non-destructive structural testing are discussed. A scale frame model of a three-story building has been build up and instrumented in order to simulate the vibration response of a multi-story building subjected to cyclic loads. Dynamic tests have been carried out by using two different types of sensors in order to make a comparative analysis of floor noise, dynamic response and phase shift in different operating conditions: (i) low cost MEMSbased accelerometers and (ii) classical piezo-electric transducers. The usage of low-cost sensors has allowed to get enough comparable performance, in terms of measured quantities, with respect to piezoelectric accelerometers. The data acquired by the system are provided to a finite element numerical model (FE) to detect the appearing, rise and distribution of local damages and to estimate a global damage level. The numerical finite element (FE) model of the structure has been developed and tuned up by means of the outcome of a structural iden-tification performed by using an Experimental and Operational Modal Analysis approaches. In particular, the modal parameters estimated have been utilised to update the FE model. A damage level estimation methodology is proposed and calibrated comparing the experimental results with the FE model prediction during cyclic failure tests of the scale frame. The life prediction of the scale model obtained by local and global damage indexes is consistent with the experimental results.

Resumo: Este trabalho propõe possíveis alterações em procedimentos experimentais de química geral envolvendo mudanças de materiais, reagentes, quantidades e concentrações de soluções, para a redução de custos e resíduos produzidos em laboratórios de ensino. Os roteiros experimentais estudados fazem parte da disciplina de Química Geral Experimental (QG-102), ministrada no Instituto de Química da Universidade Estadual de Campinas (UNICAMP), no 2° semestre de 2005 e 1° semestre de 2006. Durante esses dois semestres os alunos foram observados no desenvolvimento de suas aulas.Diante das observações, modificações foram propostas em cinco dos doze experimentos trabalhados e novos materiais foram criados, na intenção de preservar ou melhorar os aspectos didáticos dos experimentos, os resultados obtidos e o processo de aprendizagem. Alguns dos experimentos modificados reduzem em até vinte vezes a quantidade de reagentes, a quantidade de resíduos produzidos, o tempo de realização do experimento, energia elétrica e água para a limpeza dos materiais, sem comprometer os objetivos didáticos e, em alguns casos, melhorando os resultados obtidos e a compreensão dos conceitos envolvidos no experimento. Os novos roteiros experimentais foram descritos neste trabalho e aplicados para alunos ingressantes no 1° semestre de 2007, na mesma disciplina, com sucesso. Embora não avaliadas sistematicamente, as modificações propostas agradaram aos alunos e demonstraram que a preocupação com a geração e tratamento de resíduos foi despertada nos mesmos.
Abstract: This work shows possible changes introduced in experiments procedures of general chemistry involving the modification of educational materials, reagents, and solutions amount and/or concentrations, in order to diminish cost and residues. The modified experimental procedures suggested for disciplines of Laboratory of General Chemistry at Campinas State University, were conceived by observing, during two semesters, the students' pratical work at the laboratory. The aim of this project is to create new educational materials that present the same didactic performance of the conventional experimental procedures. In many respects the utilization of these new educational materials or procedures lead to the achievement of better experimental results and improved the students learning process. The new experimental procedures reduced by 20 times the amount of used reagents, and also reduced the amount of generated residues as well as the cleaning materials and energy. This work also describes new experimental procedures that were already effectively applied during experimental classes. Experiments procedures reducing by 20 times the reagent amounts, classified as micro scale, resulted in short times to carry on the experimental work, allowing free time for experimental reports and theoretical studies. The modifications proposed did not show any loss regarding the didactics purposes of the experiments. Even though not systematically evaluated, the students appreciated the modifications proposed and were concerned residue generations and managements.
