Evaluation of Human Exposure to Magnetic Fields Generated by Electric Power Systems in Complex Configurations

The international growing concern for the human exposure to magnetic fields generated by electric power lines has unavoidably led to imposing legal limits. Respecting these limits, implies being able to calculate easily and accurately the generated magnetic field also in complex configurations. Twisting of phase conductors is such a case. The consolidated exact and approximated theory regarding a single-circuit twisted three-phase power cable line has been reported along with the proposal of an innovative simplified formula obtained by means of an heuristic procedure. This formula, although being dramatically simpler, is proven to be a good approximation of the analytical formula and at the same time much more accurate than the approximated formula found in literature. The double-circuit twisted three-phase power cable line case has been studied following different approaches of increasing complexity and accuracy. In this framework, the effectiveness of the above-mentioned innovative formula is also examined. The experimental verification of the correctness of the twisted double-circuit theoretical analysis has permitted its extension to multiple-circuit twisted three-phase power cable lines. In addition, appropriate 2D and, in particularly, 3D numerical codes for simulating real existing overhead power lines for the calculation of the magnetic field in their vicinity have been created. Finally, an innovative ‘smart’ measurement and evaluation system of the magnetic field is being proposed, described and validated, which deals with the experimentally-based evaluation of the total magnetic field B generated by multiple sources in complex three-dimensional arrangements, carried out on the basis of the measurement of the three Cartesian field components and their correlation with the field currents via multilinear regression techniques. The ultimate goal is verifying that magnetic induction intensity is within the prescribed limits.

Molekularer Magnetismus und Multistabilitäten in sternförmigen cyanidgebrückten Eisen- und Übergangsmetall-Komplexverbindungen

In der hier vorliegenden Arbeit wurden neue eisenhaltige Spincrossover-Komplexerndargestellt und deren magnetische Eigenschaften untersucht. Ausgehend von früheren Ergebnissen wurden verschiedene Strategien zur Optimierung der Eisen-Spincrossover Verbindungen verfolgt. Wie schon früher dokumentiert finden sich bei Eisen-Übergangsmetall Komplexen eine Vielzahl von Spincrossover Phänomenen. Ebenso gut dokumentiert sind die Möglichen Änderungen des Spin Zustandes durch äußere Einflüsse wie Temperatur, Druck oder Licht. Darauf aufbauend wurden nunrnverschiedene Eisenkomplexe synthetisiert und auf das Spincrossover Phänomen hin untersucht. Dazu wurden zum Einen Fe(II) Komplexe vom Typ [FeL1(NCS)2] (L1 = pmea, pmap, tepa and tmpa) betrachtet und zum anderen Sternförmige Fe(III) Komplexe vom Typ [M{(CN-FeIIIL2}x]y+. (M=Fe(II), Co(III), Mo(IV), Ru(II)) undrndodecanukleare Komplexe vom Typ [(L2Fe(III)NC)5Fe(II)CNCo(III)(CNFe(III)L2)5]4+. L2= Bis(R2,3,4 -salicylidenaminoalkyl-R1-amin. Thermischen Spincrossover und LIESST zeigen [3,3/N-H/Sal-H/Fe/Co]; [3,3/N-H/Sal-H/Fe/Ru]; [3,3/N-H/sal-H/Fe/Mo]; [3,3/N-H/Sal-H/Fe/W]; FeII(pmea)(SCN)2; thermischen Spinübergang zeigt [2,3/N-H/Sal-H/Fe/Fe-Co]. Die Ethylen gebrückten Komplexe zeigen weniger guten oder gar keinen Schalteffekt im Gegensatz zum Propylen gebrückten Komplexe. Fe(II)(PMEA)(SCN)2 zeigt vollständigen thermischen Spinübergang von High Spin nach Low Spin ein LIESST und einen LiPTH Effekt.

Effects of low-density lipoprotein receptor-related protein 4 and apolipoprotein E isoforms on bone metabolism in vivo

LRP4, member of the LDLR family, is a multifunctional membrane-bound receptor that is expressed in various tissues. The expression of LRP4 by osteoblasts, its novel interaction with Wnt-signaling inhibitors Dkk1 and SOST, and the lower levels of activated beta-catenin in different bone locations described here, adds another player to the long list of established factors that modulate canonical Wnt-signaling in bone. By demonstrating that in addition to Wise, LRP4 is able to interact with two additional important modulators of Wnt- and BMP-signaling, our perspective of the complexity of the integration of BMP and Wnt-signaling pathways on the osteoblast surface has expanded further. Nevertheless the recently described association of both the SOST and LRP4 genes with BMD in humans, together with our findings suggest that LRP4 plays a physiologically important role in the skeletal development and bone metabolism not only in rodents, but in humans as well. The efficiency with which LRP4 binds both SOST and Dkk1, presumably at the osteoblastic surface, LRP4 may act as a sink and competes with LRP5/6 for the binding of these Wnt antagonists, which then are no longer available for suppression of the signal through the LRP5/6 axis. rnApoE, a 299 amino acid glycoprotein, is a crucial regulator in the uptake of triglyceride, phospholipids, cholesteryl esters, and cholesterol into cells. ApoE has been linked to osteoporosis, and such a role is further strengthened by the present of a high bone mass phenotype in ApoE null mice. Until recently, the effects of respective ApoE isoforms E2, E3, and E4, and their impact on bone metabolism, have been unclear. Here we report that respective human ApoE knockin mice display diverse effects on bone metabolism. ApoE2 mice show decreased trabecular bone volume per total volume in femoral bone and lumbar spine in comparison to ApoE3 and E4 animals. In this context, urinary bone resorption marker DPD is increased in these animals, which is accompanied by a low ratio of osteoclastogenesis markers OPG/RANKL. Interestingly, serum bone formation markers ALP and OCN are diminished in ApoE4 mice. In contrast to this finding, ApoE2 mice show the lowest bone formation of all groups in vivo. These findings cannot be explained by the low receptor-affinity of ApoE2 and subsequent decreased uptake of triglyceride-rich lipoproteins by osteoblasts, resulting in elevated levels of undercarboxylated osteocalcin. Thus, other crucial pathways relevant for bone metabolism, e. g. Wnt/beta-catenin-signaling pathways, must be, compared to the ApoE3/4 isoforms, more affected by the ApoE2 isoform.

Validation of a new method to assess the long-term Hypothalamic-Pituitary-Adrenal Activity using hair glucocorticoids as biomarkers. - Studies on pigs and laboratory Sprague-Dawley Rats

The evaluation of chronic activity of the hypothalamic-pituitary-adrenal (HPA) axis is critical for determining the impact of chronic stressful situations. The potential use of hair glucocorticoids as a non-invasive, retrospective, biomarker of long term HPA activity is of great interest, and it is gaining acceptance in humans and animals. However, there are still no studies in literature examining hair cortisol concentration in pigs and corticosterone concentration in laboratory rodents. Therefore, we developed and validated, for the first time, a method for measuring hair glucocorticoids concentration in commercial sows and in Sprague-Dawley rats. Our preliminary data demonstrated: 1) a validated and specific washing protocol and extraction assay method with a good sensitivity in both species; 2) the effect of the reproductive phase, housing conditions and seasonality on hair cortisol concentration in sows; 3) similar hair corticosterone concentration in male and female rats; 4) elevated hair corticosterone concentration in response to chronic stress manipulations and chronic ACTH administration, demonstrating that hair provides a good direct index of HPA activity over long periods than other indirect parameters, such adrenal or thymus weight. From these results we believe that this new non-invasive tool needs to be applied to better characterize the overall impact in livestock animals and in laboratory rodents of chronic stressful situations that negatively affect animals welfare. Nevertheless, further studies are needed to improve this methodology and maybe to develop animal models for chronic stress of high interest and translational value in human medicine.

Raccontare, resistere. La denuncia tra novela negra e testimonio. Affinita' e differenze in tre scrittori ispanoamericani: Serna, Walsh e Bolaño.

La tesi è incentrata sui recenti sviluppi della narrativa testimoniale dell’America Latina. Verranno presi in considerazione gli ultimi contributi critici dedicati al rapporto tra finzione e realtà in letteratura, e sarà dato spazio alla costruzione narrativa della realtà e alla nascita del testimonio, come genere a sé, che raccoglie alcune delle principali opere latinoamericane degli ultimi quaranta anni. Nello specifico, l’indagine riguarderà la rappresentazione letteraria della violenza nella narrativa di denuncia di tre autori ispoanoamericani: la novela negra di Enrique Serna, il poliziesco testimoniale di Rodolfo Walsh e la scrittura estrema di Roberto Bolaño. Obiettivo della ricerca è capire in che modo i tre scrittori hanno raccontato le loro verità alternative, provando a salvaguardare la memoria, e quali effetti hanno ottenuto. Verranno analizzate non solo le tematiche affrontate, facendo riferimento quindi al contesto storico, politico e sociale al quale si rifanno, ma saranno illustrate anche le differenti tecniche di costruzione del romanzo, dell’intreccio e della trama, e verrà isolato il ruolo del testimone (diretto o indiretto) e delle fonti, per cogliere le differenze ma anche le similitudini stilistiche e narrative di ognuna delle opere. Più in generale, dimostreremo come e quanto i testi di questi autori costituiscano in realtà una forte critica al sistema imperante e diano voce alle categorie sociali altrimenti emarginate.

Diversity of the proximal femur in humans: morphological variations of the head-neck junction

The proximal femur is a high-diversity region of the human skeleton, especially at the anterior junction between head and neck, where various bony morphologies have been recognized since mid nineteenth century. Classical literature on this topic is chaotic and contradictory, making almost impossible the comparison of data from different researches. Starting from an extensive bibliographic review, the first standardized method to score these traits has been created. This method allows representing both the anatomical diversity of the region already described in literature and a part of variability not considered before, giving few and univocal definitions and allowing to collect comparable data. The method has been applied to three identified and five archaeological European skeletal collections, with the aim of investigating the distribution of these features by sex, age and side, in different places and time periods. It has also been applied to 3D digital reconstructions of femurs from CT scan files of coxo-femoral joints from fresh cadavers. In addition to the osseous traits described in the standardized method, the presence and frequency of some features known as herniation pits have been scored both on bones and on CT scans. The various osseous traits of the proximal femur are present at similar frequencies in skeletal samples from different countries and different historical periods, even if with clear local differentiation. Some of the features examined show significant trends related to their distribution by gender and age. Some hypotheses are proposed about the etiology of these morphologies and their possible implication with the acquisition of bipedalism in Humans. It is therefore highlighted the possible relation of some of these traits with the development of disorders of the hip joint. Moreover, it is not recommended the use of any of these features as a specific activity-related marker.

Turbulence models in the atmospheric boundary layer under convective conditions

In this work a modelization of the turbulence in the atmospheric boundary layer, under convective condition, is made. For this aim, the equations that describe the atmospheric motion are expressed through Reynolds averages and, then, they need closures. This work consists in modifying the TKE-l closure used in the BOLAM (Bologna Limited Area Model) forecast model. In particular, the single column model extracted from BOLAM is used, which is modified to obtain other three different closure schemes: a non-local term is added to the flux- gradient relations used to close the second order moments present in the evolution equation of the turbulent kinetic energy, so that the flux-gradient relations become more suitable for simulating an unstable boundary layer. Furthermore, a comparison among the results obtained from the single column model, the ones obtained from the three new schemes and the observations provided by the known case in literature ”GABLS2” is made.

Effect of different management intensities on natural and human-induced carbon fluxes in a golf course in northern Italy

Turfgrasses are ubiquitous in urban landscape and their role on carbon (C) cycle is increasing important also due to the considerable footprint related to their management practices. It is crucial to understand the mechanisms driving the C assimilation potential of these terrestrial ecosystems Several approaches have been proposed to assess C dynamics: micro-meteorological methods, small-chamber enclosure system (SC), chrono-sequence approach and various models. Natural and human-induced variables influence turfgrasses C fluxes. Species composition, environmental conditions, site characteristics, former land use and agronomic management are the most important factors considered in literature driving C sequestration potential. At the same time different approaches seem to influence C budget estimates. In order to study the effect of different management intensities on turfgrass, we estimated net ecosystem exchange (NEE) through a SC approach in a hole of a golf course in the province of Verona (Italy) for one year. The SC approach presented several advantages but also limits related to the measurement frequency, timing and duration overtime, and to the methodological errors connected to the measuring system. Daily CO2 fluxes changed according to the intensity of maintenance, likely due to different inputs and disturbances affecting biogeochemical cycles, combined also to the different leaf area index (LAI). The annual cumulative NEE decreased with the increase of the intensity of management. NEE was related to the seasonality of turfgrass, following temperatures and physiological activity. Generally on the growing season CO2 fluxes towards atmosphere exceeded C sequestered. The cumulative NEE showed a system near to a steady state for C dynamics. In the final part greenhouse gases (GHGs) emissions due to fossil fuel consumption for turfgrass upkeep were estimated, pinpointing that turfgrass may result a considerable C source. The C potential of trees and shrubs needs to be considered to obtain a complete budget.

Topics in Local Economic Development

This thesis contributes to the current debate in literature about local economic development by considering two different topics: quality of institutions, and the role of clusters in innovation and productivity growth. The research is built upon three papers. The first paper deals with the analysis of the effect of administrative continuity on administrative efficiency. The analysis underlines the importance of different typologies of social capital. Findings reveal a positive impact on administrative efficiency (AE) by administrative continuity (AC) when it is coupled by bridging and linking social capital. On the contrary, bonding social capital influences negatively the effect by AC on AE. The second paper investigates the spatial interaction in levels of quality of government (QoG) among European regions. Notwithstanding the largely recognised role by institutions in the design of regional policies, no study has been conducted about the mechanisms of interaction and diffusion of QoG at regional level. This research wants to overcome this knowledge gap in literature. Findings reveal a heterogeneity in spatial interaction among groups of regions, i.e. ‘leader regions’ (Northern regions) and ‘lagging regions’ (Southern regions), when considering different mechanisms of interaction (learning / imitating competition and pure competition). Moreover, the effect of wealth on the levels of QoG is nonlinear. Finally, the third paper analyses the relation among specialization and productivity within the agricultural sector. In literature, the study of clusters dynamics has long neglected agriculture. The analysis describes the changes in sectorial specialization for eight main crop groups in Italian regions (NUTS 3), assessing the existence of spatial autocorrelations by using an exploratory data analysis. Furthermore, the effect of specialization on productivity is analysed within the main crop groups using a spatial panel data model. Findings reveal a marked tendency to specialization in the Italian agriculture, and a heterogeneous effect by specialization on productivity.

Characterization of mitochondrial genomes in bivalve species with doubly uniparental inheritance of mitochondria

Many bivalve species possess two distinct mtDNA lineages, called F and M, respectively inherited maternally and paternally: this system is called doubly uniparental inheritance (DUI). The main experimental project of my PhD was the quantification of the two mtDNAs during the development of the DUI species Ruditapes philippinarum, from early embryos to sub-adults, using Real-Time qPCR. I identified the time interval in which M mtDNA is lost from female individuals, while it is retained in males (which are heteroplasmic through all of their life cycle). The results also suggested absence of mtDNA replication during early embryogenesis, a process constituting a bottleneck that highly reduces the copy number of mtDNA molecules in cells of developing larvae. In males this bottleneck may produce cells homoplasmic for M mtDNA, and could be considered as a first step of the segregation of M in the male germ line. Another finding was the characterization, in young clams approaching the first reproductive season, of a significant boost in copy number of F mtDNA in females and of M in males. Given the age of animals in which this mtDNA-specific growth was observed, the finding could probably be the outcome of the first round of gonads and gametes production. Other lines of research included the characterization of the unassigned regions in mt genomes of DUI bivalves. These regions can harbor signals involved in the control of replication and/or transcription of the mtDNA molecule, as well as additional open reading frames (ORFs) not related to oxidative phosphorylation. These features in DUI species could be associated to the maintenance of separate inheritance routes for the two mtDNAs. Additional ORFs are also found in other animal mt genomes: I summarized the presence of gene duplications as a co-author in a review focusing on animal mt genomes with unusual gene content.

Guidelines of Special Care Dentistry in Patients with Chromosomal and Genetic syndromes

Chromosomal and genetic syndromes are frequently associated with dental and cranio-facial alterations. The aim of our study is to identify and describe the dental and craniofacial alterations typical of six genetic and chromosomal syndromes examined. Materials and Methods- A dental visit was performed to 195 patients referred from Sant’Orsola Hospital of Bologna, University of Bologna, to Service of Special Need Dentistry, Dental Clinic, Department of Biomedical and Neuromotor Science, University of Bologna. The patients recruited were 137 females and 58 males, in an age range of 3-49 years (mean age of 13.8±7.4). The total sample consisted of subjects affected with Down Syndrome (n=133), Familiar Hypophosphatemic Ricket (n=10), Muscular Dystrophies (n=12), Noonan Syndrome (n=13), Turner Syndrome (n=17), Williams Syndrome(n=10). A questionnaire regarding detailed medical and dental history, oral health and dietary habits, was filled by parents/caregivers, or patients themselves when possible. The intra-oral and extra-oral examination valued the presence of facial asymmetries, oral habits, dental and skeletal malocclusions, dental formula, dental anomalies, Plaque Index (Silness&LÖe Index), caries prevalence (dmft/DMFT index), gingivitis and periodontal disease, and mucosal lesions. Radiographic examinations (Intraoral radiographies, Orthopanoramic, Skull teleradiography) were executed according to patient’s age and treatment planning. A review of literature about each syndrome and its dental and cranio-facial characteristics and about caries, hygiene status and malocclusion prevalence on syndromic and non-syndromic population was performed. Results - The data of all the patients were collected in the “Data Collection Tables” created for each syndrome. General anamnesis information, oral hygiene habits and dmft/DMFT, PI, malocclusion prevalence were calculated and compared to syndromic and non-syndromic population results found in literature. Discussions and conclusions - Guidelines of Special Care dentistry were indicated for each syndrome, in relation to each syndrome features and individual patient characteristics.

Software zur automatischen Tumordiagnose in der funktionalen MRT der weiblichen Brust

In den westlichen Industrieländern ist das Mammakarzinom der häufigste bösartige Tumor der Frau. Sein weltweiter Anteil an allen Krebserkrankungen der Frau beläuft sich auf etwa 21 %. Inzwischen ist jede neunte Frau bedroht, während ihres Lebens an Brustkrebs zu erkranken. Die alterstandardisierte Mortalitätrate liegt derzeit bei knapp 27 %.rnrnDas Mammakarzinom hat eine relative geringe Wachstumsrate. Die Existenz eines diagnostischen Verfahrens, mit dem alle Mammakarzinome unter 10 mm Durchmesser erkannt und entfernt werden, würden den Tod durch Brustkrebs praktisch beseitigen. Denn die 20-Jahres-Überlebungsrate bei Erkrankung durch initiale Karzinome der Größe 5 bis 10 mm liegt mit über 95 % sehr hoch.rnrnMit der Kontrastmittel gestützten Bildgebung durch die MRT steht eine relativ junge Untersuchungsmethode zur Verfügung, die sensitiv genug zur Erkennung von Karzinomen ab einer Größe von 3 mm Durchmesser ist. Die diagnostische Methodik ist jedoch komplex, fehleranfällig, erfordert eine lange Einarbeitungszeit und somit viel Erfahrung des Radiologen.rnrnEine Computer unterstützte Diagnosesoftware kann die Qualität einer solch komplexen Diagnose erhöhen oder zumindest den Prozess beschleunigen. Das Ziel dieser Arbeit ist die Entwicklung einer vollautomatischen Diagnose Software, die als Zweitmeinungssystem eingesetzt werden kann. Meines Wissens existiert eine solche komplette Software bis heute nicht.rnrnDie Software führt eine Kette von verschiedenen Bildverarbeitungsschritten aus, die dem Vorgehen des Radiologen nachgeahmt wurden. Als Ergebnis wird eine selbstständige Diagnose für jede gefundene Läsion erstellt: Zuerst eleminiert eine 3d Bildregistrierung Bewegungsartefakte als Vorverarbeitungsschritt, um die Bildqualität der nachfolgenden Verarbeitungsschritte zu verbessern. Jedes kontrastanreichernde Objekt wird durch eine regelbasierte Segmentierung mit adaptiven Schwellwerten detektiert. Durch die Berechnung kinetischer und morphologischer Merkmale werden die Eigenschaften der Kontrastmittelaufnahme, Form-, Rand- und Textureeigenschaften für jedes Objekt beschrieben. Abschließend werden basierend auf den erhobenen Featurevektor durch zwei trainierte neuronale Netze jedes Objekt in zusätzliche Funde oder in gut- oder bösartige Läsionen klassifiziert.rnrnDie Leistungsfähigkeit der Software wurde auf Bilddaten von 101 weiblichen Patientinnen getested, die 141 histologisch gesicherte Läsionen enthielten. Die Vorhersage der Gesundheit dieser Läsionen ergab eine Sensitivität von 88 % bei einer Spezifität von 72 %. Diese Werte sind den in der Literatur bekannten Vorhersagen von Expertenradiologen ähnlich. Die Vorhersagen enthielten durchschnittlich 2,5 zusätzliche bösartige Funde pro Patientin, die sich als falsch klassifizierte Artefakte herausstellten.rn

Energy-efficient Communication and Estimation in Wireless Sensor Networks

This thesis focuses on the energy efficiency in wireless networks under the transmission and information diffusion points of view. In particular, on one hand, the communication efficiency is investigated, attempting to reduce the consumption during transmissions, while on the other hand the energy efficiency of the procedures required to distribute the information among wireless nodes in complex networks is taken into account. For what concerns energy efficient communications, an innovative transmission scheme reusing source of opportunity signals is introduced. This kind of signals has never been previously studied in literature for communication purposes. The scope is to provide a way for transmitting information with energy consumption close to zero. On the theoretical side, starting from a general communication channel model subject to a limited input amplitude, the theme of low power transmission signals is tackled under the perspective of stating sufficient conditions for the capacity achieving input distribution to be discrete. Finally, the focus is shifted towards the design of energy efficient algorithms for the diffusion of information. In particular, the endeavours are aimed at solving an estimation problem distributed over a wireless sensor network. The proposed solutions are deeply analyzed both to ensure their energy efficiency and to guarantee their robustness against losses during the diffusion of information (against information diffusion truncation more in general).

Integration von Heizern in thermotrope flüssigkristalline Elastomer-Aktoren und deren Anwendung beim technischen Nachbau eines menschlichen Auges

Flüssigkristalline Elastomere (LCE) zeigen eine reversible Kontraktion und werden in der Literatur auch als „künstliche Muskeln“ bezeichnet. In dieser Arbeit werden sie mit einem integrierten Heizer versehen, um eine schnelle und präzise Ansteuerung zu ermöglichen. Anschließend werden diese als Aktoren zur Realisierung eines technischen Nachbaus des menschlichen Auges verwendet. rnDas einzigartige Verhalten der flüssigkristallinen Elastomere beruht auf der Kombination der Entropie Elastizität des Elastomers mit der Selbstorganisation der flüssigkristallinen Einheiten (Mesogene). Diese beiden Eigenschaften ermöglichen eine reversible, makroskopische Verformung beim Phasenübergang des Flüssigkristalls in die isotrope Phase. Hierbei ist es wichtig eine homogene Orientierung der Mesogene zu erzeugen, was in dieser Arbeit durch ein Magnetfeld erreicht wird. Da es sich um ein thermotropes flüssigkristallines Elastomer handelt, werden in dieser Arbeit zwei Ansätze vorgestellt, um den LCE intern zu heizen. Zum einen werden Kohlenstoffnanoröhren integriert, um diese über Strahlung oder Strom zu heizen und zum anderen wird ein flexibler Heizdraht integriert, welcher ebenfalls über Strom geheizt wird. rnUm den technischen Nachbau des menschlichen Auges zu realisieren, ist die Herstellung einer flüssigkristallinen Iris gezeigt. Hierzu wird ein radiales Magnetfeld aufgebaut, welches eine radiale Orientierung des Mesogene ermöglicht, wodurch wiederum eine radiale Kontraktion ermöglicht wird. Außerdem sind zwei Konzepte vorgestellt, um eine Elastomer Linse zu verformen. Zum einen wird diese mit einem ringförmigen LCE auseinandergezogen und somit abgeflacht. Zum anderen sind acht Aktoren über Anker an einer Linse angebracht, welche ebenfalls eine Vergrößerung der Linse bewirken. In beiden Fällen werden LCE mit dem zuvor präsentierten integrierten Heizdraht verwendet. Abschließend ist das Zusammensetzen des technische Nachbaus des menschlichen Auges dargestellt, sowie Aufnahmen, welche mit diesem erzeugt wurden.
