description: HD 15082 (WASP-33) is the hottest and fastest rotating star known to harbor a transiting extrasolar planet (WASP-33b). The lack of high precision radial velocity (RV) data stresses the need for precise light curve analysis and gathering further RV data. By using available photometric and RV data, we perform a blend analysis, compute more accurate system parameters, confine the planetary mass and attempt to cast light on the observed transit anomalies. We combine the original HATNet observations and various followup data to jointly analyze the signal content and extract the transit component and use our RV data to aid the global parameter determination. The blend analysis of the combination of multicolor light curves yields the first independent confirmation of the planetary nature of WASP-33b. We clearly identify three frequency components in the 15-21 1/day regime with amplitudes 7-5 mmag. These frequencies correspond to the delta Scuti-type pulsation of the host star. None of these pulsation frequencies or their low-order linear combinations are in close resonance with the orbital frequency. We show that these pulsation components explain some but not all of the observed transit anomalies. The grand-averaged transit light curve shows that there is a ~1.5 mmag brightening shortly after the planet passes the mid-transit phase. Although the duration and amplitude of this brightening varies, it is visible even through the direct inspections of the individual transit events (some 40-60% of the followup light curves show this phenomenon). We suggest that the most likely explanation of this feature is the presence of a well-populated spot belt which is highly inclined to the orbital plane. This geometry is consistent with the inference from the spectroscopic anomalies. Finally, we constrain the planetary mass to M_p=3.27+/-0.73 M_J by using our RV data collected by the TRES spectrograph.

description: A new solution for the implementation of a HEMT negative current source is presented. The topology can be also profitably employed as a current mirror and as an active load in high-gain MMICs voltage amplifiers. A small-signal model of the proposed circuit is developed which allows to find accurate expressions for the required transfer functions (i.e., the output impedance of the current source, and the current gain of the circuit when operated as a current mirror). Design examples using Philips PML ED02AH GaAs PHEMT process are provided. Spice simulations show that a 10- kW output impedance for the current source and a 35dB voltage gain for a differential pair loaded with the proposed current mirror are easily achieved.

description: Im Rahmen der vorliegenden Arbeit soll das Vorkommen und die funktionelle Bedeutung der Peptidhormone Relaxin 2 (RLN2) und Relaxin-like Faktor (RLF) sowie der Leuzin-reichen G-Protein-gekoppelten Rezeptoren LGR7 und LGR8 an der Augenoberfläche und im Tränenwegsystem untersucht werden. Um nähere Erkenntnisse über die mögliche Bedeutung und das Expressionsmuster von RLN2 und RLF sowie der Rezeptoren LGR7 und LGR8 an der Augenoberfläche und im Tränenwegsystem zu gewinnen, wurden Untersuchungen mittels RT-PCR und Immunhistochemie an Tränendrüse, Meibom-Drüse, Konjunktiva, Kornea, primären kornealen Fibroblasten, ableitenden Tränenwegen, sowie an der humanen Sebozytenzelllinie (SZ95), Kornea- (HCE) und Konjunktivaepithelzelllinie (IOBA-NHC) durchgeführt. Mittels eines BrdU-Assays wurde die Proliferation unter RLN2- und RLF-Stimulation geprüft. Außerdem wurde der Einfluss von RLN2 und RLF auf die Migrationsfähigkeit der Epithelzelllinien mit Hilfe eine Scratch-Assays untersucht. Zellkulturexperimente wurden ebenfalls zur Analyse der Regulation von Matrix Metalloproteinasen (MMPs) und Tissue Inhibitors of MMP (TIMPs) nach RLN2- und RLF-Stimulation mittels der Real-Time PCR durchgeführt. RLN2- und RLF-mRNA konnte nur vereinzelt an Geweben der Augenoberfläche nachgewiesen werden. Der mRNA-Nachweis von LGR7 und LGR8 gelang in fast allen Geweben. In der Meibom-Drüse und vereinzelt in ableitenden Tränenwegen sowie in den 3 Zelllinien erfolgte die Detektion des LGR7-Proteins. Die Zelllinien exprimieren die Hormone und Rezeptoren auf mRNA-Ebene. RLN2 und RLF steigern die Proliferation und Migration von IOBA-NHC- und HCE-Zellen. Nach Stimulation der SZ95-, HCE- und IOBA-NHC-Zellen mit RLN2 und RLF zeigt sich eine Regulation der MMP- und TIMP-Expression. Die Ergebnisse der Expressionsuntersuchungen implizieren, dass die Hormone nicht unter physiologischen Bedingungen an der Augenoberfläche gebildet werden, sondern via Blutstrom zur Augenoberfläche transportiert werden. Der endokrine Effekt kann über die Rezeptoren LGR7 und LGR8 erfolgen. Des Weiteren deuten die proliferations- und migrationssteigernden Wirkung sowie der Einfluss auf die MMP- und TIMP-Expression auf eine Bedeutung der Hormone im Rahmen der Wundheilung hin.

description: We consider Implicit-Explicit (IMEX) Runge-Kutta (R-K) schemes for hyperbolic systems with stiff relaxation in the so-called diffusion limit. In such regime the system relaxes towards a convection-diffusion equation. The first objective of the paper is to show that traditional partitioned IMEX R-K schemes will relax to an explicit scheme for the limit equation with no need of modification of the original system. Of course the explicit scheme obtained in the limit suffers from the classical parabolic stability restriction on the time step. The main goal of the paper is to present an approach, based on IMEX R-K schemes, that in the diffusion limit relaxes to an IMEX R-K scheme for the convection-diffusion equation, in which the diffusion is treated implicitly. This is achieved by an original reformulation of the problem, and subsequent application of IMEX R-K schemes to it. An analysis on such schemes to the reformulated problem shows that the schemes reduce to IMEX R-K schemes for the limit equation, under the same conditions derived for hyperbolic relaxation. Several numerical examples including neutron transport equations confirm the theoretical analysis.

description: Il settore della vitivinicoltura, come il comparto agroalimentare nel suo complesso, ha vissuto negli ultimi decenni un’evoluzione sostanziale dettata dall’insorgere di nuove esigenze manifestate dai consumatori e dalla volontà dei produttori di garantire un’offerta sostenibile e rispettosa nei confronti dell’ecosistema. L’attuale panorama del mercato del vino è caratterizzato da un’ampia categoria di vini sostenibili (biologici, biodinamici, vegani, naturali) ciascuna delle quali con caratteri distintivi propri. Un mercato vinicolo dinamico e variegato, come quello attuale, necessita di adeguati strumenti di analisi per poter rispondere tempestivamente alle esigenze di una domanda quanto mai selettiva ed informata. Alla luce di queste considerazioni, il paper considera un segmento particolare di domanda, l’alta ristorazione, comparto che ricopre un ruolo fondamentale nel consumo di vino. Nello specifico verrà analizzato il consumo di una particolare categoria di vino sostenibile, quello cosiddetto naturale. La ricerca tenta di formulare previsioni e proporre un’interpretazione originale relativa alle possibili evoluzioni del mercato dei vini naturali in un contesto di scelte di produzione sostenibili.

description: In this paper, we propose a new broadband microwave amplifier structure using multi layer technology. Thus the design of multilayer interconnections, with combined slotlines and microstriplines, improves the integration of a feedback passive cell and permits to obtain a broadband balanced amplifier without increasing the circuit area. A first part details the structure design and the conception of this feedback cell. In a second part, the method is performed for a microwave amplifier design considering a GaAs FET commonly used in microwave circuits. A large frequency bandwidth of about 500MHz around 4 GHz is obtained. The results concerning the input VSWR, the output one and the gain are then presented. In conclusion the amplifier performances are satisfying and the feasibility of such a structure with the use of the multilayer interconnections is then evidenced.
Enhancing impact characterization and multi-criteria design optimization of glass fiber reinforced polypropylene laminates

Publisher: name: University of British Columbia
Year: 2014

description: Twintex®, a relatively new thermoplastic composite material system made of comingled polypropylene (PP) and glass fibers, has shown superior toughness in comparison with traditional glass-fiber epoxy composites. Along this improvement, this thesis aims at enhancing impact characterization of Twintex composites and developing a systematic approach for weave pattern selection and lay-up optimization of their laminates under impact. The research was conducted in experimental and numerical parts with a case study on potential application of Twintex in a highway guardrail. In the first part, a set of 180 drop-weight-impact and four-point-flexural experiments were performed for mechanical characterization of PP/glass laminates with different fiber architectures (balanced plain, balanced will, unbalanced plain, and unidirectional tape) before and after impact. Another set of the experiments was designed based on a Taguchi design of experiment (DOE) method and showed that this method has a good accuracy in predicting impact response of hybrid fiber reinforced plastic (FRP) composites such as Twintex. The X-ray microtomography and visual inspection techniques were also employed to investigate the interior and exterior damages induced to the specimens due to impact. These nondestructive evaluation techniques revealed that the impact damage mechanisms are highly dependent on the selected architecture of fibers. Also it is shown that, contrary to some previously published reports, impact resistance of FRP composites cannot be evaluated solely based on the extent of visible damages, and that inner damage along with associated damage modes must also be taken into account. Next, a case study was conducted to extract the criteria that may be used by engineers to assess impact-resistance of different Twintex FRP laminates for a potential guardrail application. Namely, a decision matrix with nine criteria was formed and three weighting techniques were developed under a multicriteria decision making environment to select the most appropriate fabric weave pattern for this specific application. The proposed multi-criteria approach is general and can assist designers to select optimum composite materials in other similar applications. The last part of this thesis deals with a simplified approach for numerical characterization (finite element analysis) of Twintex laminates under impact without a need for additional subroutine codes.

description: This research explores the digital technology experiences of students with disability in higher education in Bangladesh. The findings explicitly showcase the importance of the network of informal support systems for students with disability for empowering them to use digital technologies and, at the same time, illustrate the poverty of institutional support. The findings also depicted how technology uses helped students with disability to empower themselves and to become mostly self-dependent. However, at the same time, some service provisions and attitudes of relevant personnel led them to opt them out of availing equal opportunities to learn and to thrive.

description: This paper presents original results provided by combination of Enhancement-Mode (E-mode) with metamorphic growth of Al0.67In0.33As/Ga0.66In0.34As HEMT structure on a GaAs substrate. The devices, which are the first reported for Enhancement-Mode Al0.67In0.33As/Ga0.66In0.34As MM-HEMT’s, exhibits good dc and rf performance. Good Schottky characteristics have been obtained (a forward turn-on voltage of 0.9V and a typical reverse gate to drain breakdown voltage of 16 V). The 0.4µm gate length devices have a saturation current of 455 mA/mm at +0.8V gate voltage. Gate current studies, versus gate-to-drain extension have been observed, in the first time, in such as devices, showing gate current issued from impact ionization.

description: The paper presents investigations of optical-microwave frequency conversion processes for InP-PIN photodiode. The planar InGaAsP/InGaAs/InP heterostructure PIN photodiode operating at 1.3 µm has been used in an optoelectronic mixer configuration. The nonlinear model of the PIN photodiode responsivity has been assumed. The mathematical analysis of frequency conversion process and results of simulation are presented. The obtained results of calculation and results of measurements are compared and discussed.
Results are presented for the first fully physical, time-dependent, coupled electro-thermal simulations of microwave power FETs and MMICs, on timescales suitable for CAD. This is achieved by combining an original, analytical thermal resis-tance matrix model of time-dependent heat flow in a power FET or MMIC, with a fully physical electrical CAD model for transistors.

This would also give a new perspective on how the formulae of Joyce-Song and Kontsevich-Soibelman are related. We check the conjecture in many examples.

description: Kompositionell ungeordnete, polymere Netzwerke sind Systeme statischer Unordnung. Um aus der Zustandssumme die mittlere freie Energie zu erhalten, wird die Replikamethode verwendet. In kompositionell ungeordneten Netzwerken manifestieren sich zwei Formen statischer Unordnung. Die statische Unordnung bestimmt die Thermodynamik des kompostionell ungeordneten, polymeren Netzwerks und führen zu einem Phasenübergang 1.ter Ordnung (Quellung - Kollaps). In der Arbeit wird die Synthese heterogener polymer Netzwerk diskutiert. Es wird gezeigt, dass das System durch irreversible chemische Reaktionen im Bereich der spinodalen Entmischung eingefroren wird. Die statische Unordnung der Topologie der Netzknoten und der Heterogenität der Netzketten wird diskutiert. Zusammenfassend kann daraus die statistische Mechanik vernetzter Heteropolymere bestimmt werden.
description: Compositional disordered polymer networks are systems of quenched disorder. To determine the free energy from the canonical partition function, the replica method is used. Two distinct manifestation of quenched disorder are found in compsitional disordered polymer networks and lead to a phase transition (sweeling - collapse). The synthesis of heterogene polymer networks is discussed in the thesis. It is shown, that the system is freezed in spinodal decompositon due to irreversible chemical reactions. The static disorder due to the topology of the cross links and the heterogenity of the junctions is discussed. In conclusion, the statistical mechanics of cross linked heteropolymers can be determined.

description: Das Schulte-Koagulum wird im Universitätsklinikum Halle (Saale) zur Füllung größerer, intraoraler Knochendefekte genutzt und beseht klassischerweise aus 5 ml venösem Vollblut, einem Gelatineschwamm sowie 250 IE Thrombin und 10.000 IE Penizillin G pro Milliliter Blut. Diese Materialien werden in einem sterilen Behälter gemischt und in den knöchernen Defekt platziert. Der klinische Erfolg dieser Methode ist neben der von Schulte (1959) postulierten Retraktionsstabilität insbesondere auf positive zelluläre Effekte durch Thrombin und PDGF aus aktivierten Thrombozyten zurückzuführen. Durch Penizillin G hervorgerufene, negative Zellproliferationseffekte können durch erhöhte Thrombinkonzentrationen teilweise kompensiert werden. Thrombinrezeptor-aktivierende Peptide (100 µM) allein, hatten keinen Einfluss auf die Proliferation der MC3T3-E1 Zellen. In Kombination mit niedrigen Thrombinkonzentrationen wurde ein zusätzlicher Proliferationseffekt beobachtet.

description: The comparison of the linearity performance for three PHEMTs have been investigated in Ka band. The studied transistors are a single recessed PHEMT, a double recessed PHEMT and a double recessed dual channel PHEMT. The main result is : at a given output power level, the double recess allows a large improvement of the intermodulation ratio (IMR), thanks to its higher drain-source bias voltage capability, compared to the single recess. The second result is : the double recessed PHEMTs comparison shows that the dual channel, thanks to a more wide and uniform ransconductance distribution than the single channel, is a better solution for linearity application at 26GHz.

They are defined as simply connected prism complexes satisfying some local combinatorial conditions. We study various approaches to bucolic complexes: from graph-theoretic and topological perspective, as well as from the point of view of geometric group theory. In particular, we characterize bucolic complexes by some properties of their 2-skeleta and 1-skeleta (that we call bucolic graphs), by which several known results are generalized. We also show that locally-finite bucolic complexes are contractible, and satisfy some nonpositive-curvature-like properties.

description: In this paper the effect of a body contact to increase the breakdown voltage in GaAs based pseudomorphic HEMT has been theoretically investigated. The body contact is formed by a p-doped substrate connected to an ohmic back contact. By using a Monte Carlo simulation we show that the body contact reduces the density of holes generated by impact ionization and prevents holes from accumulating in the channel. ‘The breakdown effect is quenched as the density of acceptors in the substrate increases. This extends the range of the usable drain voltages.

description: In the modern formulation of lattice gauge-fixing, the gauge fixing condition is written in terms of the minima or stationary points (collectively called solutions) of a gauge-fixing functional. Due to the non-linearity of this functional, it usually has many solutions called Gribov copies. The dependence of the number of Gribov copies, n[U] on the different gauge orbits plays an important role in constructing the Faddeev-Popov procedure and hence in realising the BRST symmetry on the lattice. Here, we initiate a study of counting n[U] for different orbits using three complimentary methods: 1. analytical results in lower dimensions, and some lower bounds on n[U] in higher dimensions, 2. the numerical polynomial homotopy continuation method, which numerically finds all Gribov copies for a given orbit for small lattices, and 3. numerical minimisation ("brute force"), which finds many distinct Gribov copies, but not necessarily all. Because n for the coset SU(N_c)/U(1) of an SU(N_c) theory is orbit-independent, we concentrate on the residual compact U(1) case in this article and establish that n is orbit-dependent for the minimal lattice Landau gauge and orbit-independent for the absolute lattice Landau gauge. We also observe that contrary to a previous claim, n is not exponentially suppressed for the recently proposed stereographic lattice Landau gauge compared to the naive gauge in more than one dimension.

La cooperazione e lo sviluppo dei sistemi turistici locali: percorsi e ritorni in quarant'anni di sviluppo del sistema turistico riminese

description: La cooperazione tra imprese turistiche ha svolto in alcuni territori un ruolo fondamentale nello sviluppo di sistemi turistici locali “ante litteram”.
La riflessione vuole indagare il ruolo della cooperazione tra imprese (non solo in forma di società cooperative propriamente dette, ma anche di forme associative e consortili e di coordinamento imprenditoriale formalizzato) in uno dei sistemi maggiormente sviluppati (o “maturi che dir si voglia) del nostro paese ossia il territorio riminese.
Attraverso l’osservazione del ruolo delle cooperative nelle diverse fasi del mezzo secolo dello sviluppo riminese, si indaga il ruolo svolto dalle forme aggregative nelle diverse fasi dello sviluppo del sistema turistico: l’infrastrutturazione di base, lo sviluppo, la differenziazione, la riqualificazione.
La cooperazione tra imprese che in un primo momento costituisce lo strumento in cui la microimpresa prende in carico in proprio lo sviluppo e l’infrastrutturazione del territorio, diviene poi prima vincolo alla diversificazione ed allo sviluppo del prodotto e poi strumento di diversificazione e nuovamente di promozione di nuovi segmenti turistici, per operare infine come elemento di intervento sulle crisi aziendali.
L’analisi delle storie delle cooperative tra esercenti di impianti balneari, tra albergatori, tra operatori di particolari micro territori, mostrano le potenzialità ed i limiti dei sistemi di aggregazione “orizzontali” tra imprese e della loro collaborazione con i soggetti incaricati della promozione turistica del territorio.

description: This report describes progress made during the first 18 months of BioExcel-2 executing the project’s planned demonstrator research projects (the “Use Cases”) as well as research work done by BioExcel in response to the COVID-19 pandemic. The report demonstrates how important challenges in biomolecular modelling and simulation can be tackled effectively using the software and expertise developed by the CoE and by exploiting large-scale computing resources. Success stories and lessons learned are highlighted, in particular where these have had the most significant impact on advancing what can be achieved using (pre-)exascale computing. With regards to COVID-19, core applications and workflow tools were rapidly adapted to perform large-scale mutational and free energy analyses to elucidate the evolutionary and structural relationships of SARS-CoV2 to other coronavirus species and strains as well as host sensitivity, viral adaptation, and the cell entry mechanism of the virus. This approach as well as molecular dynamics simulation and docking were used to screen for large numbers of potential therapeutic candidates and to study the inhibitory mode of action of potential drug targets. Progress has been made in Use Cases 1 and 3 developing and evaluating computational pipeline protocols that use various combinations of the core BioExcel applications GROMACS, HADDOCK and PMX to perform free energy and docking calculations for the design of antibody-based drugs and other therapeutics, including mutational analysis. The workflow tools developed by the project are enabling these pipelines to execute as containerised workflows on HPC resources, demonstrating how the work being done is set to achieve the ultimate goal of shortening the overall time and effort taken to develop new and better therapeutics through large-scale computational biomolecular modelling and simulation. In Use Case 2, parallel execution of containerised HADDOCK and the necessary data movement underpinning this execution is similarly orchestrated by PyCOMPSs, demonstrating how (pre-)exascale HPC resources will be able to be used to study significant fractions of the interactions of biomolecules encoded by the human genome. In Use Case 4, QM/MM simulation with GROMACS and CP2K using large-scale computing resources are set to improve electrospray ionization mass spectrometry - a key analytical technique in proteomics - and, combined with free energy calculations using PMX, are enabling the design of fluorescent proteins enabling the high-resolution monitoring of cellular functions, gene expression, protein-protein interactions, intra-cellular interactions in living systems as well as understanding and finding novel strategies to tackle disease.

description: In all nontrivial cases renormalization, as it is usually formulated, is not a change of integration variables in the functional integral, plus parameter redefinitions, but a set of replacements, of actions and/or field variables and parameters. Because of this, we cannot write simple identities relating bare and renormalized generating functionals, or generating functionals before and after nonlinear changes of field variables. In this paper we investigate this issue and work out a general field-covariant approach to quantum field theory, which allows us to treat all perturbative changes of field variables, including the relation between bare and renormalized fields, as true changes of variables in the functional integral, under which the functionals Z and W = ln Z behave as scalars. We investigate the relation between composite fields and changes of field variables, and show that, if J are the sources coupled to the elementary fields, all changes of field variables can be expressed as J-dependent redefinitions of the sources L coupled to the composite fields. We also work out the relation between the renormalization of variable-changes and the renormalization of composite fields. Using our transformation rules it is possible to derive the renormalization of a theory in a new variable frame from the renormalization in the old variable frame, without having to calculate it anew. We define several approaches, useful for different purposes, in particular a linear approach where all variable changes are described as linear source redefinitions. We include a number of explicit examples.

description: Effector of Transcription (ET)-Faktoren sind durch hoch konservierte C-terminale DNA- und Zink- bindende, nur bei Pflanzen gefundene, repetitive Protein-Domänen charakterisiert. Zusätzlich besitzen sie eine Domäne mit struktureller Ähnlichkeit zu einer DNA-Einzelstrang schneidenden Domäne (GIY-YIG) prokaryontischer Reparaturproteine. Für eine funktionelle Charakterisierung von ET wurden drei experimentelle Ansätze angewandt: a) Synthese von ET-Faktoren in Bakterien und die Erzeugung spezifischer Antikörper (nanobodies), b) die biochemische Analyse der DNA-Bindungsaktivität sowie die in vivo Untersuchung zur Funktion einer DNA-Einzelstrang schneidenden Proteindomäne und c) die genetische Charakterisierung der ET-Genfamilie auf der Basis von T-DNA-Mutanten und RNAi-Konstruktionen. Die beschriebenen Ergebnisse charakterisieren ET-Faktoren als neue, redundant funktionierende Transkriptionsfaktoren mit DNA-Einzelstrang-schneidender Aktivität. Mutantenanalyse belegt darüber hinaus wichtige Funktionen während der Entwicklung des männlichen Gametophyten sowie der frühen Embryogenese und Endosperm-Entwicklung.

description: Anhand von 301 Patienten, die im Jahre 1998 im Rahmen einer multizentrischen Studie an einem Schilddrüsenkarzinom operiert wurden, wurde die Bedeutung des Resektionsausmaßes für die chirurgische Komplikationsrate bei Patienten mit einem Schilddrüsenkarzinomrezidiv (n=38) untersucht. Die häufigsten Komplikationen bei den Rezidivoperationen waren der passagere Hypoparathyreoidismus (13,2%), die transiente Rekurrensparese (10,5%), die permanente Rekurrensparese (7,9%) und der permanente Hypoparathyreoidismus (6,6%). Wir konnten in unserer Untersuchung keine signifikanten Unterschiede hinsichtlich des Auftretens vom Komplikationen bei Rezidiv- versus Primäreingriffen (n=263) finden, unabhängig vom Resektionsausmaß. Bei der Untersuchung aller Malignompatienten fand sich gerade kein statistisch signifikanter Einfluss der Darstellung des Nervus laryngeus recurrens bezüglich einer Reduzierung der permanenten Pareserate (p=0,06). Wir konnten zeigen, dass die Lymphknotendissektion ein Risikofaktor für die Entwicklung einer passageren (p=0,011) und eines permanenten (p=0,014) Hypoparathyreoidismus, für das Auftreten eines Horner- Syndroms (p=0,05) und für das Notwendigwerden einer Reoperation (p=0,028) bei allen Tumorpatienten war. Bei Rezidivpatienten mit einem pT4-Tumor wurde postoperativ signifikant häufiger eine passagere Rekurrensparese diagnostiziert (p<0,05), während bei pT1-3-Rezidiven signifikant häufiger ein permanenter Hypoparathyreoidismus (p<0,05) auftrat.
description: Based on the data of 301 patients who underwent operation of thyroid carcinoma as part of a multicenter study in 1998, the significance of the extent of resection on the surgical complication rate was investigated with particular interest on recurrent thyroid carcinoma (n=38). The most common complications observed after reoperation were transient hypoparathyroidism (13.2%), transient recurrent laryngeal nerve paresis (10.5%), permanent recurrent laryngeal nerve paresis (7.9%), and permanent hypoparathyroidism (6.6%). No difference could be found comparing complication rates after reoperation and primary operation (n=263), independent of the sugical extent. The identification of the recurrent laryngeal nerve correlated almost significantly with a reduction of the permanent recurrent laryngeal nerve paresis rate (p=0.06). Analysing the data of all carcinoma patients, ymph node dissection coulb be identified as a risk factor to develop transient (p=0.011) hypoparathyroidism, permanent (p=0.014) hypoparathyroidism, Horner’s syndrome (p=0.05) and the necessity to perform reoperation (p0.028). Anlyising only patients who underwent reoperation, patients with pT4-tumor more often developed transient recurrent laryngeal nerve paresis (p<0.05) whereas patients with pT1-3-tumor more often developed and permanent hypoparathyroidism (p<0.05).

description: L’evoluzione della presenza delle imprese sociali nel sistema del welfare italiano, dopo la fase degli appalti di manodopera e quella dei servizi per conto, si confronta con lo scenario della gestione dei servizi pubblici con lo strumento dell’accreditamento. 
Ciò pone nuove sfide al sistema della cooperazione sociale, che viene chiamata ad uniformarsi a standard di servizio e modelli tariffari di remunerazione richiesti dall’ente pubblico concedente il servizio e rischia di abbandonare quella spinta all’innovazione ed all’integrazione con la società civile in quanto non richiesta dai contratti di servizio.
La “deriva contrattualistica” delle imprese sociali accreditate verso i soli standard di servizio si affianca alla deriva lavoristica determinando una “sterilizzazione” dell’apporto innovativo della cooperazione sociale nella gestione dei servizi.  Il soggetto pubblico concedente, spinto dai vincoli di bilancio, definirà nei contratti un livello di servizio minimo senza richiedere al soggetto accreditato un compenso per attività aggiuntive ed innovative.
Ciò porta le imprese sociali ad allinearsi ai modelli di gestione definiti nel modello di accreditamento accettando un processo di normalizzazione della propria gestione adeguandosi da espressione della società civile a soli fornitori di servizio pubblico.
Le imprese sociali inserite nel sistema dell’accreditamento si trovano inoltre a gestire in modo diretto un servizio pubblico utilizzando denaro pubblico, sia pure in una regolamentazione privatistica (si pensi alla gestione del personale e delle forniture), e quindi devono rivedere i propri sistemi di governance e di accountability prevedendo forme e procedure di controllo interno, partecipazione e rendicontazione che garantiscano maggiormente stakeholders interni ed esterni.
Il bilancio sociale, i sistemi di controllo della qualità tecnica e relazionale dei servizi, i modelli di partecipazione di soci, lavoratori ed utenti devono misurarsi con un diverso ruolo di “fornitori privati di servizi pubblici”.
Il sistema dell’accreditamento ridefinisce in radice il concetto di “servizio pubblico” portandolo da una nozione soggettiva ad una oggettiva richiedendo alle imprese sociali una revisione degli strumenti di governo e controllo.

description: Social Enterprise is increasingly becoming a pressing area of study in European faculties, and likewise, a broad range of literature has been produced on the various, relating arguments.
One of the aspects least focused upon, however, regards the issue of governance; which is a fundamental aspect when defining a type of governing system that could lead to an improvement in the efficiency and effectiveness of social enterprises. The need to combine both social and economic aims in the decision making process also emphasizes the importance of stakeholder participation.
Furthermore, seeing as how social enterprises work in an environment of high public involvement, whether it be with public entities or with the community as a whole, issues such as business administration and activity supervision, come to be of high importance. The production of social utility goods and/or services is directed toward a plurality of local actors, which are to be furthermore guaranteed a high level of accountability and transparency.
This paper explores governance through an in-depth analysis and comparison of the legislation of eleven countries on social enterprise or social cooperatives (Belgium, Finland, France, Greece, Italy, Latvia, Lithuania, Poland, Portugal, Spain, and United Kingdom).

description: “Public accreditation certification” of private institutions and differentiation of institutional forms of public
bodies define a convergence between public and private non profit provider of social services in Italy
In Italy the system of public provision of social health and educational services historically developed as an
expression of the central and local government. While the private institutions that provide the same services
was not included in the public system. They maintained a wide autonomy in organizing services, but they
paid the autonomy with the absence of a strong financial support. In the last thirty years , the process of
concessions before, and then of public-private partnership, and now, the general accreditation for private
institutions and the increasing strategic and financial autonomy for the public institutions is leading to a
different frame of reference. Private bodies if they want to work in partnership with the public institutions and
receive public funds have to obtain accreditation so they reduce their differentiation and autonomy. Instead
the public, in search of new opportunities and new funding, tend to adopt private law models. This path
suggest us to affirm a new concept of "public service" objective and not subjective, and to seek common
forms of regulation. We argue that should be requested more transparency and social control to the private
operators who managed public services with public funding. While to the public bodies should be requested
a greater responsibility and competitiveness with private entities that have the same standard of service. The
“accreditation revolution” requires new governance and accountability tools.

description: Il presente studio muove dal progetto di esaminare la documentazione materiale degli strumenti musicali e degli oggetti sonori, utile alla comprensione sia dei loro particolari acustici, musicali e formali, sia degli aspetti comunicativi e simbolici. 
La conoscenza del contesto di rinvenimento, così come la loro datazione e descrizione, aiutano a comprenderne l’uso e la funzione e consentono di ricostruire il ruolo della musica nella sfera rituale e cultuale e di definire cosa la musica e il far musica significassero per le società antiche. 
Unici testimoni diretti e interni della pratica musicale, gli strumenti musicali e gli oggetti sonori sono i mezzi con cui si manifestano i messaggi e i valori relativi alla vita e alle attività musicali nell’antichità.
Coniugando i metodi della musicologia e dell’archeologia, il loro studio permette di gettare luce sulla recezione di elementi della cultura e della musica presso le elites greche d’Occidente per le quali essa svolgeva un ruolo paideutico e politico, oltre che sull’adozione da parte delle aristocrazie indigene dell’Italia meridionale di modelli ellenici. Inoltre, l’indagine consente di individuare alcuni aspetti relativi alla musica non solo presso le popolazioni italiote e siceliote ma anche, per quanto riguarda la Sicilia, nell’ambiente punico contiguo, talora evidenziando una stretta connessione con la vita quotidiana e con le attività legate al lavoro.
