Technological processes study for high value health ingredients and foods production

This PhD thesis describes set up of technological models for obtaining high health value foods and ingredients that preserve the final product characteristics as well as enrich with nutritional components. In particular, the main object of my research has been Virgin Olive Oil (VOO) and its important antioxidant compounds which differentiate it from all other vegetables oils. It is well known how the qualitative and quantitative presence of phenolic molecules extracted from olives during oil production is fundamental for its oxidative and nutritional quality. For this purpose, agronomic and technological conditions of its production have been investigated. It has also been examined how this fraction can be better preserved during storage. Moreover, its relation with VOO sensorial characteristics and its interaction with a protein in emulsion foods have also been studied. Finally, an experimental work was carried out to determine the antioxidative and heat resistance properties of a new antioxidant (EVS-OL) when used for high temperature frying such as is typically employed for the preparation of french fries. Results of the scientific research have been submitted for a publication and some data has already been published in national and international scientific journals.

From inverted pendulum to N-link chain: inertial sensors-based assessment of movement kinematics and dynamics for functional evaluation and rehabilitation

Despite several clinical tests that have been developed to qualitatively describe complex motor tasks by functional testing, these methods often depend on clinicians' interpretation, experience and training, which make the assessment results inconsistent, without the precision required to objectively assess the effect of the rehabilitative intervention. A more detailed characterization is required to fully capture the various aspects of motor control and performance during complex movements of lower and upper limbs. The need for cost-effective and clinically applicable instrumented tests would enable quantitative assessment of performance on a subject-specific basis, overcoming the limitations due to the lack of objectiveness related to individual judgment, and possibly disclosing subtle alterations that are not clearly visible to the observer. Postural motion measurements at additional locations, such as lower and upper limbs and trunk, may be necessary in order to obtain information about the inter-segmental coordination during different functional tests involved in clinical practice. With these considerations in mind, this Thesis aims: i) to suggest a novel quantitative assessment tool for the kinematics and dynamics evaluation of a multi-link kinematic chain during several functional motor tasks (i.e. squat, sit-to-stand, postural sway), using one single-axis accelerometer per segment, ii) to present a novel quantitative technique for the upper limb joint kinematics estimation, considering a 3-link kinematic chain during the Fugl-Meyer Motor Assessment and using one inertial measurement unit per segment. The suggested methods could have several positive feedbacks from clinical practice. The use of objective biomechanical measurements, provided by inertial sensor-based technique, may help clinicians to: i) objectively track changes in motor ability, ii) provide timely feedback about the effectiveness of administered rehabilitation interventions, iii) enable intervention strategies to be modified or changed if found to be ineffective, and iv) speed up the experimental sessions when several subjects are asked to perform different functional tests.

Safety, Security And safeguards In GEN IV sodium fast reactors

This work presents first a study of the national and international laws in the fields of safety, security and safeguards. The international treaties and the recommendations issued by the IAEA as well as the national regulations in force in France, the United States and Italy are analyzed. As a result of this, a comparison among them is presented. Given the interest of the Japan Atomic Energy Agency for the aspects of criminal penalties and monetary, also the Japanese case is analyzed. The main part of this work was held at the JAEA in the field of proliferation resistance (PR) and physical protection (PP) of a GEN IV sodium fast reactor. For this purpose the design of the system is completed and the PR & PP methodology is applied to obtain data usable by designers for the improvement of the system itself. Due to the presence of sensitive data, not all the details can be disclosed. The reactor site of a hypothetical and commercial sodium-cooled fast neutron nuclear reactor system (SFR) is used as the target NES for the application of the methodology. The methodology is applied to all the PR and PP scenarios: diversion, misuse and breakout; theft and sabotage. The methodology is applied to the SFR to check if this system meets the target of PR and PP as described in the GIF goal; secondly, a comparison between the SFR and a LWR is performed to evaluate if and how it would be possible to improve the PR&PP of the SFR. The comparison is implemented according to the example development target: achieving PR&PP similar or superior to domestic and international ALWR. Three main actions were performed: implement the evaluation methodology; characterize the PR&PP for the nuclear energy system; identify recommendations for system designers through the comparison.

Nuove pratiche turistiche e sostenibilita'. I profili del turista lento in Valnerina

Il presente lavoro intende analizzare il tema del turista lento che nell���ultimo decennio si �� diffuso nel dibattito scientifico e culturale connesso al tema della sostenibilit�� e della qualit�� della vita e nel contesto dell���approccio teorico strutturato intorno alle nuove tendenze dello Slow Tourism. In una prima parte la tesi delinea il framework della sostenibilit�� con particolare attenzione al recente dibattito in corso sulla ���decrescita��� e l������a-crescita��� come concetti alternativi al paradigma della crescita. Successivamente viene evidenziato il modo in cui le idee di base ed i principi dello sviluppo sostenibile sono stati applicati al turismo e indagato il legame tra sostenibilit�� e responsabilit�� e come questo configura l���emergere di un turismo ���responsustable���. In tale contesto viene analizzata la relazione tra turismo e lentezza in cui a filosofia slow non deve essere interpretata come un fenomeno del momento o un innovativo prodotto turistico, ma come una filosofia di vita, un movimento sociale e globale che negli ultimi anni ha caratterizzato i diversi ambiti socio-economici delle comunit�� locali. Successivamente attraverso una review della letteratura nazionale ed internazionale sul tema, la pluralit�� di prospettive teoriche vengono sistematizzate in tre ipotesi di lettura riconducibili a tre paradigmi: sostenibilit��- slow tourism- territorio; benessere ��� slow tourism ��� qualit�� della vita; esperienza ��� slow tourism ��� consumo. Nella seconda parte del lavoro viene presentata l���indagine empirica a partire dall���analisi di contesto del territorio in cui si �� svolta l���attivit�� di ricerca, i nove comuni del Comprensorio Turistico della Valnerina in Umbria, con particolare riferimento all���analisi dell���offerta e della domanda turistica. Successivamente sono presentati i risultati di un questionario somministrato a 620 turisti attraverso il quale viene analizzato il profilo motivazionale, le esperienze di fruizione turistica e la percezione della qualit�� territoriale da parte del turista e delineato il profilo del turista slow in Valnerina.

Beyond socialism: Tanzanian theatre, neoliberalism and foreign aid complexity

Theatralit��t ist ein g��ngiges Konzept, um Theater in Afrika zu definieren. Wird dieses Konzept angewendet, so treten die historischen Unterschiede zwischen den verschiedenen Theaterformen in den Hintergrund. Deshalb ist es wichtig, Theater in einen kulturellen Kontext zu stellen, aus dem das Theater entsteht. Dadurch k��nnen nationale und internationale Suprastrukturen, die die sozialpolitische und wirtschaftliche Atmosph��re bestimmen, analysiert werden,. Da sich die aktuelle ���globale��� Entwicklung auf neoliberale Grunds��tze st��tzt, ist es offensichtlich, dass man Theater nicht diskutieren kann, ohne n��her auf Neoliberalismus, Imperialismus, Kapitalismus, Entwicklungshilfe und Geberpolitik einzugehen.rnDerzeit werden die meisten Theaterprojekte in Tansania durch die Entwicklungshilfe oder ausl��ndische Geberorganisationen unterst��tzt. Diese Organisationen stellen finanzielle Mittel zur Verf��gung, um Theaterproduktionen auf unterschiedlichem Niveau zu erm��glichen. Diese Spendenpraxis hat zu der Fehlannahme gef��hrt, dass Theater nur dann ein Theater ist, wenn es durch ausl��ndische Organisationen finanziert wird. Jedoch ist es offensichtlich, dass diese finanziellen Mittel eine gro��e Rolle in der Machtpolitik spielen. Diese Studie untersucht deshalb die Frage: Welchen Einfluss hat die neoliberale Politik, insbesondere durch die Entwicklungshilfe, auf das Theater in Tansania? Die Arbeit deckt einmal die Verbindung zwischen dem produzieren Theater und den verschiedenen dominierenden politischen Richtungen ��� von Nationalismus bis Neoliberalismus ��� auf. Dar��ber hinaus wird gezeigt, dass diese Verbindungen es dem Theater erschweren, diese Suprastrukturen zu vermeiden, durch die es finanziert wird. Das bedeutet, dass die neoliberale Politik mit seinen Merkmalen von Einengung, Unterdr��ckung und Ausbeutung auch ein eingeengtes, unterdr��cktes und ausbeuterisches Theater hervorbringt. Dieser Studie bezeichnet ein solches Theater als Theater (Neo-)Liberalismus. Es ist ein Theater, das apolitisch auftritt, aber tats��chlich unter der neoliberal Politik des freien Markts und der Subventionsstreichungen ums ��berleben k��mpft.rnIndem diese Verbindungen zwischen Theater, Entwicklungshilfe und Geberorganisationen erl��utert werden, kommt diese Forschung zu folgendem Ergebnis: Die Geberorganisationen haben kein Recht, unabh��ngig von der H��he ihrer Spende, in die Souver��nit��t eines Staates einzugreifen oder ein neues System einzuf��hren. Deshalb sollte die Losl��sung von ausl��ndischen Geberl��ndern an erster Stelle stehen, damit sich das Theater ganz entwickeln und unabh��ngig ��berleben kann. Es ist deshalb notwendig, das Konzept des Volkstheaters neu zu definieren. Das Theater soll wieder mit den Initiativen von Menschen zu tun haben und ihre eigenen Themen in einem gewissen zeitlich und r��umlichen Rahmen ansprechen.rnrn

Applying erosion damage mapping to asses and quantify off-site effects of soil erosion in Switzerland

In order to fill existing knowledge gaps in the temporal and spatial distribution of soil erosion, its sources and causes, as well as in relation to its off-site impacts, erosion damage mapping of all visible erosion features was carried out at three study sites in Switzerland. The data illustrate that about one-quarter of the cultivated land was affected by water erosion. Observed mean annual soil loss rates are considered rather low (0.7���2.3 t/ha/y) compared to other European countries. However, substantial losses of >70 t/ha were recorded on individual plots. This paper focuses on the spatial aspects of soil erosion, by observing and comparing the study areas in a 1-year period from October 2005 to October 2006. The analyses illustrate that the sites differ considerably in average soil loss rates, but show similar patterns of off-site effects. In about one-third of the damaged plots an external source of surface runoff upslope contributed to the damage (run-on). Similarly, more than 50 per cent of the soil eroded on arable land deposited downslope on adjacent plots, roads, public/private infrastructure, etc., and 20 per cent of it reached open water bodies. Large amounts of eroded soil which deposit off-site, often related to slope depressions, are considered muddy floods and were frequently observed in Switzerland. Mapping, in conclusion, helps to sheds light on some of the important challenges of today, in particular: to comprehensively assess socioeconomic and ecological off-site effects of soil erosion, to attribute off-site impacts to on-site causes, and to raise awareness of all stakeholders involved, in order to improve ongoing discussions on policy formulation and implementation at the national and international levels.

Climate Change and International Law. Exploring the Linkages Between Human Rights, Environment, Trade and Investment

Mapping the relevant principles and norms of international law, the paper discusses scientific evidence and identifies current legal foundations of climate change mitigation adaptation and communication in international environmental law, human rights protection and international trade regulation in WTO law. It briefly discusses the evolution and architecture of relevant multilateral environmental agreements, in particular the UN Framework Convention on Climate Change. It discusses the potential role of human rights in identifying pertinent goals and values of mitigation and adaptation and eventually turns to principles and rules of international trade regulation and investment protection which are likely to be of crucial importance should the advent of a new multilateral agreement fail to materialize. The economic and legal relevance of rules on tariffs, border tax adjustment and subsidies, services and intellectual property and investment law are discussed in relation to the production, supply and use of energy. Moreover, lessons from trade negotiations may be drawn for negotiations of future environmental instruments. The paper offers a survey of the main interacting areas of public international law and discusses the intricate interaction of all these components informing climate change mitigation, adaptation and communication in international law in light of an emerging doctrine of multilayered governance. It seeks to contribute to greater coherence of what today is highly fragmented and rarely discussed in an overall context. The paper argues that trade regulation will be of critical importance in assessing domestic policies and potential trade remedies offer powerful incentives for all nations alike to participate in a multilateral framework defining appropriate goals and principles.

The Swiss cohort of elderly patients with venous thromboembolism (SWITCO65+): rationale and methodology

Venous thromboembolism (VTE) is common and has a high impact on morbidity, mortality, and costs of care. Although most of the patients with VTE are aged ���65��years, there is little data about the medical outcomes in the elderly with VTE. The Swiss Cohort of Elderly Patients with VTE (SWITCO65+) is a prospective multicenter cohort study of in- and outpatients aged ���65��years with acute VTE from all five Swiss university and four high-volume non-university hospitals. The goal is to examine which clinical and biological factors and processes of care drive short- and long-term medical outcomes, health-related quality of life, and medical resource utilization in elderly patients with acute VTE. The cohort also includes a large biobank with biological material from each participant. From September 2009 to March 2012, 1,863 elderly patients with VTE were screened and 1003 (53.8��%) were enrolled in the cohort. Overall, 51.7��% of patients were aged ���75��years and 52.7��% were men. By October 16, 2012, after an average follow-up time of 512��days, 799 (79.7��%) patients were still actively participating. SWITCO65+ is a unique opportunity to study short- and long-term outcomes in elderly patients with VTE. The Steering Committee encourages national and international collaborative research projects related to SWITCO65+, including sharing anonymized data and biological samples.

Hospital for joint diseases participates in international spine registry Spine Tango after successful pilot study

Spine Tango is currently the only international spine registry in existence. It was developed under the auspices of Eurospine, the Spine Society of Europe, and is hosted at the University of Bern, Switzerland. The HJD Spine Center successfully tested Spine Tango during a 3-month pilot study and has since expanded documentation activities to more surgeons. Workflow integration and dedicated research staff are key factors for such an endeavor. Participation enables benchmarking against national and international peers and outcome research and quality assurance of surgical and non-surgical treatments.
