Negli anni il programma ha portato al riconoscimento di Riserve della Biosfera che gli Stati Membri si impegnano a gestire nella prospettiva della conservazione delle risorse. L’Organismo Gestore dell’Area Protetta, partendo, da un lato, dalla consapevolezza della ricchezza ambientale che caratterizza il suo territorio e, dall’altro, del contesto di sviluppo antropico elevato in cui essa è situata, ha riconosciuto nel programma MAB un’opportunità per incrementare le sue attività di protezione e potenziamento delle risorse. Questo articolo descrive i primi risultati ottenuti negli studi preliminari per la Designazione al MAB, con particolare attenzione sia alle opportunità di implementazione di progetti legati al marchio “Collina Po”, creato dall’Organo di Gestione del Parco, si ain termini di scambio di ‘best practices’ con altre Riserve di Biosfera.

Il programma dell'universo

CERN Document Server

Lloyd, Seth

2006-01-01

Da quando l'universo ha avuto inizio, ha cominciato a calcolare il proprio comportamento. All'inizio il computer-universo produceva strutture semplici, particelle elementari e leggi elementari della fisica; col passare del tempo ha processato "informazioni" sempre più complesse, producendo strutture sempre più intricate (galassie, stelle, pianeti), ma sempre secondo leggi semplici. Ogni cosa deve quindi la propria esistenza alla capacità intrinseca della materia e dell'energia di processare informazione. Se si decifrasse fino in fondo si potrebbe, con un computer quantistico di dimensioni ridotte, comprendere l'universo nel suo insieme.

We report findings on teacher learning and student outcomes, and reflect on practical implications and directions for future research on the programme. In the “Dialogic Video Cycle” (DVC six teachers participated in a year-long intervention built on effective components of TPD and using videos of teachers’ own practices as tools for reflection and basis for group discussions. We compared the DVC with a traditional TPD programme (n= 4 teachers. Additionally, students (N= 226 were assessed regarding their motivational orientations and individual beliefs. Results show that effective TPD components could successfully be implemented in the DVC and that this new and innovative programme enhances teachers’ performance in classroom discourse and affects students’ interest in the subject, self-efficacy and domain-specific self-concept of ability positively. Thus, the DVC seems a promising tool to foster teacher learning with an impact on perceived student motivation and learning. Presentiamo un programma innovativo per lo sviluppo professionale degli insegnanti (TPD, centrato sulla ridefinizione della conduzione di interazioni verbali in classe.

2011-03-15

The Dutch government considers the transition process to be necessary and stimulates investments in energy innovations in the built environment. This innovation effort is the programme 'Energy Leap' (Energiesprong), which is being carried out by the Steering Group Experimental Housing (SEV) on behalf of the Dutch Ministry of the Interior and Kingdom Relations (BZK). The programme is derived from the Innovation Agenda for Energy in the Built Environment. The examples in this book are intended to inspire (potential) participants in the Experiment Energy Leap for Small-scale Urban Areas. The examples focus explicitly on the reduction of CO2 emissions in urban areas, and thus, in addition to CO2 reduction on a building level, the aspects of energy supply, (local) energy production and the energy infrastructure [Dutch] Het SEV-programma Energiesprong (SEV is Stuurgroep Experimenten Volkshuisvesting) beoogt een substantiele bijdrage te leveren aan de condities waaronder de energietransitie effectief tot stand kan komen. In dit basisplan wordt uiteengezet hoe de markt daartoe moet kunnen komen en welke activiteiten daarvoor worden ondersteund, opgezet en/of uitgevoerd vanuit Energiesprong. Het SEV-programma Energiesprong wordt in opdracht van het Ministerie van Binnenlandse Zaken en Koninkrijksrelaties (BZK) uitgevoerd. Het programma is afgeleid van de Innovatie Agenda energie Gebouwde Omgeving. Dit voorbeeldenboek dient ter inspiratie van (potentiele) deelnemers aan het Experiment Energiesprong kleinschalige Binnenstedelijke Gebieden.

Seven years ago, the Clean Air Schools Program was launched to encourage people to use less energy and improve the indoor environment. In 2012, the program Energy and Built Environment will no longer pay specific attention focused on school buildings. Therefore, the market needs to jump in. 'Market initiatives' refers to projects, products and services that contribute to the realization of Clean Air Schools and which are not initiated by the Dutch government [Dutch] Zeven jaar geleden is het Frisse Scholen Programma gestart om gemeenten en scholen te stimuleren om minder energie te gebruiken en het binnenmilieu te verbeteren. In 2012 biedt het programma Energie en Gebouwde Omgeving geen ruimte meer voor specifieke aandacht gericht op scholen. Daarom zal het stokje overgedragen moeten worden aan marktpartijen. Met 'marktinitiatieven' wordt gedoeld op projecten, producten en diensten die bijdragen aan de realisatie van Frisse Scholen en niet door de Rijksoverheid worden geinitieerd.

Full Text Available

Obiettivi: aumento del 10% dell’uso delle cinture di sicurezza anteriori e posteriori e del 20% dei seggiolini per bambini nella Regione del Veneto.

Metodi: il Programma Regionale di Prevenzione dei Traumi da Traffico è stato varato nel 1998 e rifinanziato nel 2002 per un secondo triennio. Fa capo alla Direzione per la Prevenzione dell’Assessorato alle Politiche Sanitarie del Veneto, coinvolge i Dipartimenti di Prevenzione di tutte le Aziende ULSS del Veneto e ha come capofila l’azienda ULSS 7 di Pieve di Soligo (TV. Nell’ambito del programma, il 16 maggio 2003 è stata avviata una campagna di marketing sociale finanziata dalla fondazione CARIVERONA e commissionata ad un’ agenzia pubblicitaria leader del settore. La campagna è stata preceduta da ricerca formativa con 19 focus group e 12 interviste, volta ad analizzare il punto di vista dei diversi target, nonché degli attori principali coinvolti (Forze dell’Ordine, autoscuole, etc. Dopo un test di gradimento, la campagna è partita con spot televisivi e radiofonici, inserzioni nei giornali e manifesti informativi destinati alle scuole medie superiori, alle scuole guida nonché agli ambulatori dei medici di famiglia. Attraverso i media si sostiene una serie di azioni nel territorio che coinvolgeranno le amministrazioni comunali, le forze di polizia e le associazioni di volontariato.

Risultati: l’efficacia della campagna viene valutata attraverso due distinte rilevazioni dell’uso delle cinture di sicurezza/seggiolini, confrontando i dati raccolti prima della campagna e dopo.

Conclusioni: i traumi da traffico rappresentano nel Veneto un’importante causa di mortalità e morbosità. Il programma regionale ha utilizzato la tecnica innovativa del marketing sociale come strumento essenziale per sostenere i cambiamenti comportamentali necessari a prevenire l’incidentalità da traffico nel

This paper demonstrates how a CO{sub 2} emission reduction programme can change the competition between the two power production technologies which will probably dominate the future of the Italian power industry: the coal fired USC steam power plant and the natural gas fired CCGT power plant. An economic value of the CO{sub 2} emission is calculated, in order to make the short-run-marginal-cost (or the long-run-marginal-cost). equal for both technologies, under a CO{sub 2} emission trading scheme and following a single-plant specific CO{sub 2} emission homogenizing approach. [Italian] Si dimostra come un programma teso alla riduzione delle emissioni di CO{sub 2} possa mutare la competivita' tra le due tecnologie per la produzione termoelettrica che saranno dominanti nel prossimo futuro in Italia: le centrali a carbone USC e le centrali CCGT a gas naturale. Si calcola il prezzo delle emissioni di CO{sub 2} per valutare il costo marginale di breve periodo (o il costo marginale di lungo periodo) per entrambe le tecnologie, avvalendosi di un programma di emission trading e utilizzando un approccio di omogeneizzazione delle emissioni di CO{sub 2} specifiche di ogni impianto.

In 2007, the Dutch Ministry of Waterways and Public Works (currently the Ministry of Infrastructure and Environment) launched the multi-annual plan 'Voortvarend Besparen 2007-2010' (Energetic Saving) that aims to stimulate captains of barges into more energy efficient sailing behavior. The program aims to encourage energy efficient operation of ships, resulting in a fuel saving and a 5% reduction in CO2 emissions in inland shipping in 2010 compared to 2007. In the final measurement, questionnaires were sent to the barge skippers to find out if the inland shipping sector succeeded in realizing the target and to examine to what extent the Energetic Saving program contributed to the CO2 reduction. [Dutch] In 2007 heeft het Ministerie van Verkeer en Waterstaat (nu het Ministerie van Infrastructuur en Milieu) het startsein gegeven voor het meerjarenprogramma VoortVarend Besparen (2007 - 2010) met als doel schippers te stimuleren tot energie-efficienter vaargedrag. Het programma dient energie-efficienter vaargedrag te stimuleren resulterend in een brandstofbesparing en een 5% reductie van CO2 emissies in de binnenvaartsector in 2010 ten opzichte van 2007. In de eindmeting is door middel van enquetes onder binnenvaartschippers onderzocht of de binnenvaartsector deze doelstelling heeft gehaald, en in welke mate het VoortVarend Besparen programma heeft bijgedragen aan deze CO2-reductie.

Habitat networking: a new chance for the otter in Europe?

Directory of Open Access Journals (Sweden)

Claus Reuther

1995-12-01

Full Text Available Abstract One of the main problems for otter protection in Germany as well as in Europe is the fragmentation and isolation of populations. In Germany a thriving population exists in the eastern parts of the country while in the central parts only isolated populations remain, and in the western parts the species is extirpated. On the basis of this situation a habitat network program is in progress with the aim to protect and restore not only those habitats where the otter still remains but also those habitats which can function as a network to connect the thriving with the isolated populations. This network focuses on existing protected wetlands or rivers and restoration activities in wetlands or rivers. The situation of the otter in Europe (excluding Scandinavia and the British Isles is comparable to that in Germany. There are stable or thriving populations in the eastern and western parts while in Central Europe only isolated populations remain. Following the German otter habitat network program possibilities are shown and discussed to establish a habitat network program for the otter on a European level. Riassunto Ripristino di una rete di ambienti favorevoli alla lontra: una nuova possibilità per la specie in Europa? - Uno dei principali problemi riguardanti la conservazione della lontra (Lutra lutra in Germania, come del resto in Europa, è la frammentazione e l'isolamento delle popolazioni. In Germania, una cospicua popolazione esiste nella parte orientale, mentre in quella centrale sono presenti nuclei isolati; nella porzione occidentale del paese la specie è invece praticamente estinta. Tenendo presente questa situazione, è stato avviato un programma di ricostruzione di una rete di ambienti favorevoli alla lontra con l'obiettivo di proteggere e ripristinare non solo gli ambienti in cui la specie è attualmente presente, ma anche quelli che possono funzionare come rete di

Il programma di radicale naturalizzazione della mente. Note su alcuni assunti concettuali

Directory of Open Access Journals (Sweden)

Aldo Stella

2014-12-01

Full Text Available The Project of a Radical Naturalization of Mind. Remarks on Some Conceptual Assumptions - In this paper we address the program of the radical naturalization of the mind and, in particular, the materialist monism perspective which is the product of that program. Our aim is to identify the fundamental assumptions on which the program is based. The first assumption we recognize and critically discuss concerns the correspondentist conception of truth. A second assumption is related to the view that the study of the mind consists solely in the identification of causal relations and laws that govern mechanical processes, while the only investigations that can be considered scientific are those which are based on the principle of the closure of the physical world. In conclusion, we show that the most significant assumption of this program is the negation of subjectivity and consciousness, which are reduced to unconscious, non-intelligent processes. The problem we identify with respect to this reduction is that the fundamental distinction between empirical conditions and the conditions of intelligibility is disregarded.

Full Text Available Nowadays, the need to develop and boost new forms of sustainable urban mobility to replace urban transport is a key iusse, addressed by European Commission with a big effort in terms of research, strategies and initiatives. In this context, two relevant instruments identified to reach this goal are integrated planning at all the mobility levels and its management. The former may be realized through the processing of PUMS (Urban Plan of Sustainable Mobility, while the latter through Intelligent Transport Systems (ITS. Among the other sustainable transport services, car sharing is expected to become efficient and is expected to limit the use of private cars, thus facilitating multi-modal for public transports. The present text deals with a presentation of the state-of.art practices in terms of car sharing, particularly referring to the case of Turin.

Full Text Available Il contributo si colloca in un programma interdisciplinare volto alla valorizzazione e la tutela del fiume, attraverso il controllo dei flussi e l’attivazione di simbiosi. Si integrano, con un approccio che parte dalla progettazione ambientale, le tematiche urbane, paesaggistiche, tecnologiche ed ecologiche, per orientare lo sviluppo del territorio in termini di tutela e valorizzazione delle risorse, e per recuperare le discontinuità rappresentata oggi dal fiume, in alcuni contesti urbani, conferendole maggiore riconoscibilità e potenzialità. Nello specifico si indaga il rapporto tra L’Aquila e il fiume Aterno per individuare, a livello locale, le strategie perseguibili per il recupero delle connessioni tra l’ambito fluviale e urbano, per la valorizzazione del territorio e il ripristino della funzionalità dell’acqua nel suo ciclo vitale.

Radiation Protection Programme in Nuclear Medicine Practice

International Nuclear Information System (INIS)

Alarfaj, Abd-I.M.

2003-01-01

This paper specifies the main elements of the radiation protection programma (RPP) that should be estabished for each practice, which involves radiation exposure. Practices of nuclear medicine have been considered as an example, since among the 245 installations which are conducting different practices with radiation sources in the Kingdom of Saudi Arabia, there are 78 installations dealing with nuclear medicine practices. Reviewing the RPP in these nuclear medicine installations, it may be easily concluded that the RPPs for the majority of these installations do not respond to the requirements of the regulatory body of the Kingdom, which is King Abdulaziz City for Science and Technology (KACST). This may be attributed to a set of different reasons, such as shortage in understanding the main elements of the RPP as well as in applying methodologies

Full Text Available La maggior parte degli sforzi per trasformare l’economia sub-sahariana negli anni Ottanta e Novanta faceva seguito ai cosiddetti “accordi di Washington”; questi sforzi avevano l’obiettivo di ridimensionare il ruolo dello Stato e liberalizzare i prezzi agricoli. La strategia prescritta funzionò per alcuni, ma non per la maggioranza dei produttori agricoli; all’inizio del XXI secolo è necessario, ancora una volta, un “momento di ripensamento”. I responsabili delle politiche agricole suggeriscono ora che,per indurre un cambiamento efficace, il nuovo modo di pensare deve fare i conti con modelli inappropriati di coltivazione, cogliere le dimensioni sociali e politiche dei cambiamenti indotti dalle moderne tecniche di coltivazione e venire a patti con i locali modi di comprensione dei contesti complessi (Scoones, Devereux, Haddad 2005, p. 3.

Welzijnsorganisaties, onderzoekinstellingen, overheidsinstellingen en woningcorporaties zijn alle potentiële partners in stedelijke herstructureringsprogramma’s. Het combineren van de belangen van deze organisaties vormt een interessante managementuitdaging. Ook is het een uitdaging om een informatiesysteem te ontwikkelen dat tegemoet komt aan de informatiebehoefte van alle partners, zowel de afzonderlijke organisaties, als het collectief. Dit artikel zal deze uitdaging van informatiemanagement bespreken, door een case study naar cooperative knowledge production te presenteren. De case study heeft betrekking op het Rotterdamse stedelijk investeringssprogramma “Pact op Zuid”, een programma waarin tussen 2006 en 2016 1.5 miljard euro wordt geïnvesteerd in stedelijk gebied met 190.000 inwoners. Dit artikel geeft allereerst inzicht in literatuur over innovatieconfiguraties en lerende netwerken, concepten die belangrijk zijn om de complexiteit van stedelijke renovatie en cooperative knowledge production te begrijpen. Het bespreekt eveneens hoe cooperative knowledge production binnen Pact op Zuid plaatsvond.

Evaluation of the search and rescue LEEWAY model in the Tyrrhenian Sea: a new point of view

Channel Regional Model developed in the framework of PON-TESSA (Programma Operativo Nazionale; National Operative Program – TEchnology for the Situational Sea Awareness project. The main objective of the work is to validate a new approach of leeway calculation that relies on a real person in water (PIW event, which occurred in the Tyrrhenian Sea in July 2013. The results show that by assimilating a human body to a cylinder and estimating both the transition from laminar to turbulent boundary layer and the drag coefficients, it can be possible to solve a force balance equation, which allows the search area to be estimated with good approximation. This new point of view leads to the possibility of also testing the same approach for other different categories of targets, so as to overcome the limitations associated with the calculation of the leeway in the future by means of standard statistical law.

Waarom is het belangrijk en wat weten we over de praktijk van interdisciplinaire samenwerking? Recent buitenlands onderzoek licht een tipje op van de sluier. Naar aanleiding van de interimevaluatie van het Stimuleringsprogramma Biodiversiteit in 2003, werd er door de evaluatiecommissie op aangedrongen het tweede deel van het onderzoeksprogramma interdisciplinair op te zetten en te focussen op biodiversiteit in agrarisch gebied. Ook hier was vergroting van de beleidsrelevantie van de resultaten de achterliggende reden. Aangezien het Stimuleringsprogramma Biodiversiteit ooit is opgezet naar aanleiding van een advies van RMNO en NRLO, is onderzocht hoe begrippen als interdisciplinariteit en beleidsrelevantie zijn geoperationaliseerd in het programma. Dit resulteerde in het rapport 'Een studie over (bio)diversiteit'.

primer lugar, se eligieron para la realizacion de esos circuitos las aleaciones de indio, metal liquido a temperatura ambiente. Se estudio el comportamiento de dos eutecticos de indio frente a algunos materiales de construccion y a principios de 1960 se construyo el primer circuito de prueba de indio-galio. Como iesultado de estudios ulteriores, se instalaron modelos de circuitos de indio-galio, con una actividad en el irradiador equivalente a unos 100 g de Ra, en el reactor IRT de la Academia de Ciencias de la Republica Socialista Sovietica de Georgia, asi'como un circuito de prueba de indio-galio-estafio in el canal del reactor IRT del Instituto de Energia Atomica de la Academia de Ciencias de la Union Sovietica. Por ultimo, en 1962, se instalo un circuito de trabajo de indio-galio-estano en el reactor IRT de la Academia de Ciencias de la Republica Socialista Sovietica de Latvia para efectuar irradiaciones en escala semiindustrial. La actividad maxima en el irradiador equivale a 30 000 g de Ra. La memoria consta de las siguientes partes: 1.

Full Text Available Diventa difficile, in questa situazione sfuggire alla logica della precarietà, così come riuscire a stabilire un discorso continuativo con una o più persone, se non ricorrendo a qualche trucco “tecnico” migliorativo. Rimane il grosso vantaggio rappresentato dalla comunicazione diretta, quasi in tempo reale, se le persone sono in quel momento collegate al programma, quindi sono in grado di replicare. Diventa quindi il possibile veicolo e motore di movimenti di opinione, di gruppi spontanei di persone, di emozioni che possono diventare “oceaniche”, come quando, in uno stadio gremito, tutti si muovono all’unisono sotto il segno della ola. Vengono così soddisfatte la partecipazione e la reciprocità nel bisogno di relazione, e viene soddisfatto il bisogno delle persone di narrazione, ovvero il bisogno di raccontare con leggerezza ad un possibile interlocutore, o ad una platea, la propria storia in frammenti, attraverso commenti puntuali, espressioni di intento, canzoni e immagini. La narrazione, oggi, è fenomeno sempre più raro, grazie al crollo del valore aggiunto rappresentato dall’esperienza, e si è trasformata in storytelling.

GASCOD, a near-ultraviolet and visible differential optical spectrometer, was developed at CNR's FISBAT Institute in Bologna, Italy, and first tested at Terra Nova Bay station in Antarctica (74.6 deg S, 164.6 deg E) during the summer expeditions 1988-1990 of PNRA (PNRA is the national research program in Antarctica, 'Programma Nazionale di Ricerche in Atartide'). A comparison with coincident O3 total column measurements taken in the same Antarctic area is presented, as is another comparison performed in Italy. Also introduced is an updated model for solar zenith measurements taken from a ground-based, upward-looking GASCOD spectrometer, which was employed for the 1991-92 winter campaign at Aer-Ostersund in Sweden (63.3 deg N, 13.1 deg E) during AESOE (European Arctic Stratospheric Ozone Experiment). The GASCOD can examine the spectra from 300 to 700 nm, in 50 nm steps, by moving the spectrometer's grating. At present, it takes measurements of solar zenith radiation in the 310-342 nm range for O3 and in the 405-463 nm range for NO2.

Three different methods have been used to condition chloride salt wastes coming from pyro-processes. Two of them allow to synthesise sodalite, a naturally occurring mineral containing chlorine: the former, starting from Zeolite 4A, which transforms the zeolite into sodalite; the latter, which starts from kaolinite, giving sodalite as well. In addition, a new matrix, termed SAP (SiO 2 -Al 2 O 3 -P 2 O 5 ), has been synthesised. It is able to form different mineral phases which occlude fission metals. The products from the different processes have been fully characterised. In particular the chemical durability of the final waste forms has been determined using the standard product consistency test. According to the results obtained, SAP seems to be a promising matrix for the incorporation of chloride salt wastes from pyro-processes. Financial support from the Nuclear Fission Safety Programme of the European Union (projects ACSEPT, contract FP7-CP-2007- 211 267, and SACSESS, Collaborative Project 323282), as well as from Italian Ministry for Economic Development (Accordo di Programma: Piano Annuale di Realizzazione 2008-2009) is gratefully acknowledged.

Lo scopo della ricerca è l’indagine nel quartiere sud-ovest di Palmira, i cui limiti sono definiti a sud-est dal muro perimetrale dell’Agorà, a sud e a sud-ovest dal settore delle Mura di Diocleziano compreso tra l’Agorà e la Porta di Damasco, a nord-ovest e a nord-est dalla Via Colonnata Trasversale e dalla Grande Via Colonnata. Cinta su tre lati da vie colonnate e inclusa all’interno della cerchia muraria tardo-antica, quest’area è conosciuta come “quartiere residenziale”. Malgrado la sua centralità nel tessuto urbano - finora peraltro escluso da sistematiche attività di ricerca e di scavo – nel quartiere non risultano evidenti i resti di grandi monumenti pubblici o religiosi, come nelle aree adiacenti, e appare quindi ragionevole supporne una prevalente, se non esclusiva, destinazione residenziale. Appare quindi necessario una verifica di tale ipotesi attraverso una rigorosa indagine scientifica.

1. Work on a counter system designed for electron capture studies has shown that the diameter of the anode wire in a high-pressure proportional counter can have an important influence on the energy resolution obtained in measurements of low-energy radiations. In a counter working at a pressure of 12 atmospheres the width of the pulse distribution due to 13.5 keV K-capture radiations could be changed from 65% to 17% by changing the wire diameter from 0.0076 mm to 0.0025 mm. This phenomenon is interpreted as an effect of positive ion space charge in the avalanche. For a given gas gain and primary radiation the density of positive ions in the avalanche increases rapidly with pressure of the filling gas, and when the accompanying electric fields are large enough to affect the last stages of the multiplication process the energy resolution of the counter deteriorates. Decrease in diameter of the anode wire increases the externally applied field in the region where multiplication takes place, thus tending to counteract the effect of space charge. Use of 0.0025 mm anode wires has proved satisfactory in new measurements of L/K capture ratios made with a multiwire counter system working at pressures up to 12 atmospheres. The results obtained for L/K capture ratios of Ge{sup 71} and Kr{sup 79} are 0.115 and 0.112 respectively. The same counting system has also been used in a search for M capture in these two isotopes. The low energy of the M capture radiation, 180 eV in Ge{sup 71} and 260 eV in Kr{sup 79}, and its low intensity relative to that of K capture, makes accurate measurement difficult; but peaks attributable to M capture were observed in pulse spectra of both sources. 2. Low-Background Counting - Recent observations made on a combination of proportional counter and scintillation counters (operating as shields) show that there are some real difficulties in devising a relatively simple system of this kind. The performance is inherently very satisfactory but practical matters such as long-term gas purity are difficult to overcome. 3. Studies of Electron Attachment - An approach to systematic observations in gases and mixtures of moment in proportional counting is described. It is hoped that such measurements as are effected with this arrangement will be valuable in enlarging the field of application of the counters. (author) [French] 1. Les travaux consacres a la mise au point d'un dispositif de comptage destine a l'etude de la capture electronique ont montre que le diametre du, fil constituant l'anode dans un compteur proportionnel a haute pression peut avoir une influence importante sur le pouvoir de resolution en energie obtenu dans les mesures de rayonnements de faible energie. Dans un compteur travaillant sous une pression de 12 atmospheres, l'amplitude de la repartition des impulsions dues aux rayonnements de capture K de 13,5 keV a pu etre ramenee de 65% a 17%. en reduisant de 0,0076 mm a 0,0025 mm le diametre du fil. Ce phenomene est interprete comme constituant un effet de la charge spatiale en ions positifs dans l'avalanche. Pour un gain et un rayonnement primaire donnes, la densite des ions positifs dans l'avalanche s'accroit rapidement avec la pression du gaz de remplissage, et lorsque les champs electriques d'accompagnement sont assez grands pour affecter les derniers stades du processus de multiplication, le pouvoir de resolution en energie du compteur diminue. Toute diminution du diametre de l'anode entraine un accroissement du champ applique exterieurement, dans la region ou se produit la multiplication, ce qui tend a contrecarrer l'effet de la charge spatiale. L'emploi de fils d'un diametre de 0,0025 mm a donne des resultats satisfaisants lors de nouvelles mesures des rapports de capture L/K effectuees au moyen d'un dispositif de comptage a fils multiples, travaillant sous des pressions pouvant atteindre 12 atmospheres. Les resultats obtenus pour les rapports de capture L/K du Ge{sup 71} et du Kr{sup 79} sont de 0,115 et 0,112 respectivement. On a utilise le meme dispositif de comptage pour etudier la capture M dans ces deux isotopes. La faible energie du rayonne- ment de capture M, soit 180 eV pour le Ge{sup 71} et 260 eV pour le Kr79, ainsi que sa faible intensite comparee a celle de la capture K, rendent difficiles les mesures precises; cependant, des pics imputables a la capture M ont ete observes dans les spectres d'impulsions des deux sources. 2. Comptage d'une activite de fond peu elevee - Des observations recentes faites avec un dispositif comprenant un compteur proportionnel et des compteurs a scintillateurs (ces derniers agissant comme ecrans protecteurs) montrent que la mise au point d'un dispositif relativement simple de ce genre presente de serieuses difficultes. Le fonctionnement est tres satisfaisant en soi, mais certains problemes pratiques, tels que le maintien d'un gaz a l'etat pur pendant une longue periode, sont difficiles a resoudre. 3. Etudes sur l'accumulation d'electrons - On decrit une methode d'observation systematique portant sur les gaz et melanges importants pour le comptage proportionnel. On espere que les mesures effectuees grace au dispositif correspondant s'avereront utiles en permettant d'elargir le champ d'application des compteurs. (author) [Spanish] 1. Los trabajos de perfeccionamient o de un dispositivo de recuento destinado al estudio de la captura electronica demuestran que el diametro del alambre anodico de un contador proporcional de elevada presion puede ejercer una influencia considerable sobre el poder de resolucion energetica obtenido en la medicion de radiaciones de baja energia. En un contador que trabaje a la presion de 12 atmosferas, la amplitud de la distribucion de los impulsos debidos a radiaciones de captura K de 13,5 keV, puede reducirse de 65 a 17% sustituyendo el alambre de 0,0076 mm de diametro por otro de 0,0025 mm. Este fenomeno se interpreta como un efecto de la carga espacial de los iones positivos en la avalancha. Para una amplificacion gaseosa y una radiacion pri- maria determinadas, la densidad de los iones positivos en la avalancha aumenta rapidamente con la presion del gas contenido en el contador, y cuando los campos electricos concomitantes tienen suficiente intensidad para afectar las ultimas fases del proceso de multiplicacion, el poder de resolucion del contador disminuye. La reduccion del diametro del alambre anodico trae aparejado un aumento de la intensidad del campo externo en la zona donde se verifica la multiplicacion, tendiendo asi a contrarrestar el efecto de la carga espacial, pero el empleo de alambres anodicos de 0,0025 mm ha dado resultados satisfactorios en nuevas mediciones de las razones de captura L/K efectuadas con un contador de hilos multiples funcionando a presiones de hasta 12 atmosferas. Los resul- tados obtenidos para la razon de captura L/K del Ge{sup 71} y del Kr{sup 79} son 0,115 y 0,112 respectivamente . El mismo sistema de recuento se ha empleado para investigar una posible captura M en estos dos isotopos. La baja energia de la radiacion emitida por captura M, a saber 180 eV en el Ge{sup 71} y 260 eV en el Kr{sup 79}, asi como su reducida intensidad en relacion con la correspondiente a la captura K, dificultan una medicion exacta; sin embargo, en los espectros de impulsos de ambas fuentes se han observado maximos que pueden atribuirse a la captura M. 2. Recuento de bajas actividades de fondo. - Observaciones recientes efectuadas con un dispositivo formado por un contador proporcional y contadores de centelleo (que funcionan como pantalla protectora) revelan que la construccion de un dispositivo relativamente sencillo de este tipo ofrece ciertas dificultades. El funcionamiento es de por si muy satisfactorio, pero algunos problemas practicos, tales como el mantenimiento del gas al estado puro durante uen tiempo largo, son dificiles de resolver. 3. Estudios sobre acumulacion de electrones. - El autor describe un procedimiento de observacion sistematica de las propriedades de los gases y mezclas utilizadas en el recuento proporcional.

Full Text Available Il patrimonio edilizio urbano è un bene che caratterizza l’identità dell’uomo che con esso ha vissuto; la conoscenza della realtà originaria, la conservazione e valorizzazione nel tempo comportano interventi di tipo documentale che possono interessare sia gli aspetti costruttivi degli edifici, connessi a dimensioni e geo-localizzazione, sia quelli legati alla forma urbana, sia ancora altri più specifici di tipo storico-artistico e materico. Le nuove tecnologie laser di misura terrestre, integrate da sensori di posizionamento e fotografici, consentono di rilevare in tempi ridotti e di rappresentare anche spazialmente sia singole unità edilizie sia interi insediamenti urbani. Le grandi quantità di dati acquisiti costituiscono un arricchimento della conoscenza geometrica di base, fornita in genere da rappresentazioni cartografiche “vettoriali o raster”. Il lavoro descrive un test di scansione laser, statica e cinematica, avviato sul territorio di Dalmine (Bergamo nell’ambito di un programma di interventi comunali di tutela paesaggistica, conservazione dei caratteri costruttivi e valorizzazione degli insediamenti storici della città, realizzati negli anni venti del secolo scorso e identificativi del suo passato di città-industria. L’approccio al rilievo tende altresì a validare una procedura operativa, basata su componenti tecnologiche innovative, semplice, sufficientemente economica e convenientemente applicabile all’indagine su aree urbane.

Full Text Available La logistica urbana rappresenta oggi una delle principali sfide per una mobilità sostenibile. La distribuzione delle merci in città paga infatti in competitività quei problemi di cui è in parte responsabile: traffico, inquinamento, incidenti etc. Negli ultimi anni la sensibilità su questi aspetti di sostenibilità ambientale è cresciuta in maniera netta, e a livello europeo molta strada è stata fatta per predisporre le risposte più adeguate. Il progetto europeo CityLog, finanziato nell’ambito del Settimo Programma Quadro, vede oggi collaborare diciotto partner europei coordinati dal Centro Ricerche Fiat per migliorare la logistica urbana agendo lungo tre direttrici: •\tservizi telematici orientati alla logistica, per dare un contributo decisivo al miglioramento della pianificazione delle missioni utilizzando strumenti per il routing ottimizzato dei veicoli e il supporto informativo costante agli autisti dei veicoli; •\tsoluzioni a bordo veicolo, che rappresentano un fattore chiave per aumentare la flessibilità operativa di camion e furgoni; •\tunità di carico innovative, accuratamente progettate per essere utilizzate su veicoli diversi in missioni diverse. Ne deriva pertanto una famiglia di container compatti con un layout interno riconfigurabile così da poter essere utilizzati per scopi diversi.

The paper evaluates surface coal mining in the Dal'vostugol' association. Five surface mines of the association mined 13.8 Mt in 1980, 105,900 m/sup 3/ of overburden were removed, overburden to coal ratio was 7.67 m/sup 3//t, labor productivity per miner was 663 t/month, mining cost 2.70 ruble/t. Use of powerful walking draglines for mining, overburden removal and spoil bank formation influenced mining schemes and permitted labor productivity to be increased. Mining schemes without transport of overburden are shown . The following types of mining equipment were used: EhSh-15/90, EhSh-14/75, EhSh-10/60 and EhSh-10/70 draglines, EhKG-4.6u and EhVG-4I face shovels. Mining and geologic conditions are described: climatic conditions are characterized by intensive temperature fluctuation. Air temperature in January ranges from minus 26.8 C to minus 41.0 C and in July from 7.2 C to 31.9 C, the annual precipitation is 622 mm. Thickness of frozen soil in winter ranges from 2.5 to 3.0 m. Geologic conditions of the basin are analyzed: coal seam thickness, depth, coal properties, ash, sulfur, volatile matter, moisture, calorific value, stratification of overburden, mechanical properties of overburden, ground water and water influx. Operation of the Dal'vostugol' mines is described on the example of the Severo-Vostochnyi surface mine, the largest of the region (47% of the coal output). The following aspects of mine operation are evaluated: coal output, economic analysis, mining cost, mining equipment, earthmoving equipment (draglines), mine haulage, effects of climates (particularly equipment repairs), mining schemes, failures of excavators, innovation and safety.

There is increasing interest in the distribution of sustainable gases (H2, H2/CO, CH4/CO2) and imported gases, such as LNG. The composition of these 'new' gases can differ greatly from the traditional distributed gases. The combustion characteristics may cause undesired effects in household appliances. One of the solutions is to develop equipment that can accept a wide range of gases and mixtures thereof. To this end, within the EDGaR-program (Energy Delta Gas Research) the project 'new gas sensors' is started by the Energy Research Centre of the Netherlands (ECN), Delft University of Technology (TUD) and DNV-KEMA/Gasunie to develop a boiler in which the new gases can be used [Dutch] Er is toenemende interesse in de distributie van duurzame gassen (H2 , H2/CO, CH4/CO2 ) en geimporteerde gassen, zoals LNG. De samenstelling van deze 'nieuwe' gassen kan sterk verschillen van de traditioneel gedistribueerde gassen. De verbrandingseigenschappen kunnen ongewenste effecten veroorzaken in huishoudelijke apparatuur. Een van de oplossingen is het ontwikkelen van apparatuur die een breed scala aan gassamenstellingen kan accepteren. Hiertoe is binnen het EDGaR-programma (Energy Delta Gas Research) een project 'new gas sensors' gestart met ECN, TU Delft en DNV-KEMA/Gasunie voor het ontwikkelen van een CV-ketel die geschikt is voor de nieuwe gassen.

This report for the Swiss Federal Office of Energy (SFOE) takes a look at a project for the realisation of a small hydro-power plant on the alpine stream 'Ri Secco' in the municipality of Quinto, southern Switzerland. The Ri Secco partly flows in a steep canyon. The elevation difference of 810 or 620 m (depending on the location of the water deviation from the stream) is favorable to the installation of a small-scale high-head power plant. The report presents details on the hydrological data and the dimensioning of the installation. Several variants are considered, which also include two possible penstock diameters for each weir location. The electricity production expected is discussed, as is the economic viability of the project.

Dose assessment in internal dosimetry needs computational and interpretative tools that allow carrying out, as a first step, an evaluation of intake on the base of bioassay measurements or WBC measurements, and as a second step, dose evaluation on the base of estimated intake. In the frame of the MIDIA Co-ordination (WBC operating in Italy), in the first months of 1997 a census on methodologies for dose evaluation in internal contamination has been proposed. A technical form has been sent to all the WBC Centres allowing an accurate description of modalities used in each centre. 9 out of 17 centres sent the answers to the technical form in time. In this paper all the forms filled in are reported. A careful comparative evaluation of the answers has been made both for routine monitoring and for special monitoring. The various radionuclides present in the Italian reality, calculation methodologies both for intake and dose, hypotheses adopted for date, path and modalities of contaminations are also presented. Proposals for conforming to the methodology in Italy after the introduction of the models following ICRP 60 publication that are the base of the Euratom 96/29 Directive are also discussed. [Italiano] La valutazione di dose in contaminazione interna necessita di strumenti interpretativi che permettano di effettuare in una prima la valutazione dell`intake sulla base delle misure dei campioni biologici o del corpo intero (WBC), ed in una seconda fase la valutazione della dose sulla base dell`intake. All`interno del coordinamento MIDIA dei WBC operanti in Italia e` stato proposto, nel primo trimestre del 1997, un censimento sulle metodologie di valutazione di dose da contaminazione interna. Ai diversi centri e` stato inviato una scheda tecnica che, mediante un particolareggiato schema di domande, aiutava i diversi centri nella esposizione delle modalita` di valutazione di dose che ogni centro segue. 9 au 17 centri WBC operanti al momemnto in Italia hanno inviato la risposta alla scheda tecnica in tempo utile.

The environmental pollution is continuously increasing owing to anthropic activity. High concentrations of heavy metals may have drastic consequences on human health, particularly on children development. Conventional approaches have high economical and environmental costs that do not allow soil decontamination unless sites are particularly valuable. Phytoextraction uses plants producing biomass to transfer metals from the soil to the aerial parts of the plants at the expenses of solar energy. This work illustrates the activity performed within a Life-Environment european project in order to verify whether phytoremediation can be transferred from the laboratory scale to the field scale. [Italian] L'inquinamento del suolo dovuto all'accumulo di metalli come conseguenza delle attivita' umane sta continuamente e drammaticamente aumentando. Principali cause di contaminazione sono l'accumulo di rifiuti urbani, l'utilizzo di fertilizzanti, il traffico motorizzato, gli inceneritori, le centrali termoelettriche, le emissiioni industriali nocive, lo sfruttamento e dismissione di miniere. La decontaminazione di suoli inquinati da metalli e' un problema estremamente difficile da trattare. La bonifica di suoli inquinati da metalli mediante l'utilizzo di piante metallofite e/o agronomiche (fitoestrazione) emerge quindi come una tecnica estremamente interessante. Viene percio' illustrato il progetto PhyLeS (Phytoextraction of Lead from Soil), un progetto pilota finanziato dal programma Europeo Life/Ambiente (DG XI), che si propone di verficare i potenziali vantaggi e la trasferibilita' della metodica di fitoestrazione assistita dalla scala di laboratorio a quella di campo.

Testing two or more data sets for the hypothesis that they are sampled form the same population is often required in environmental data analysis. Typically the available samples have a small number of data and often then assumption of normal distributions is not realistic. On the other hand the diffusion of the days powerful Personal Computers opens new possible opportunities based on a massive use of the CPU resources. The paper reviews the problem introducing the feasibility of two non parametric approaches based on intrinsic equi probability properties of the data samples. The first one is based on a full re sampling while the second is based on a bootstrap approach. A easy to use program is presented. A case study is given based on the Chernobyl children contamination data. [Italiano] Nell`analisi di dati ambientali ricorre spesso il caso di dover sottoporre a test l`ipotesi di provenienza di due, o piu`, insiemi di dati dalla stessa popolazione. Tipicamente i dati disponibili sono pochi e spesso l`ipotesi di provenienza da distribuzioni normali non e` sostenibile. D`altra aprte la diffusione odierna di Personal Computer fornisce nuove possibili soluzioni basate sull`uso intensivo delle risorse della CPU. Il rapporto analizza il problema e presenta la possibilita` di utilizzo di due test non parametrici basati sulle proprieta` intrinseche di equiprobabilita` dei campioni. Il primo e` basato su una tecnica di ricampionamento esaustivo mentre il secondo su un approccio di tipo bootstrap. E` presentato un programma di semplice utilizzo e un caso di studio basato su dati di contaminazione di bambini a Chernobyl.

Full Text Available In qualità di docente, fondatore e direttore del Laboratori d’Urbanisme de Barcelona presso la ETSAB dal 1969 al 2012, l’architetto e urbanista spagnolo Manuel Solà-Morales ha curato la riforma chiave della pedagogia urbana della scuola di Barcellona. Deciso a superare la tendenza tecnocratica che aveva contraddistinto l’architettura e la pianificazione spagnola durante l’ultimo decennio del regime di Franco, l’obiettivo di Solà-Morales fu la formazione di quello che definì l’‘architetto-urbanista’ attraverso un programma propedeutico che accorpava architettura e urbanistica in un’unica disciplina. Sotto l’egida della morfologia urbana, il nuovo corso di Urbanistica impartito dal corpo docente del LUB diede il via allo studio della città e della sua storia come base principale di ogni progetto architettonico e urbano. / As professor and founding director of the Laboratori d’Urbanisme at the ETSAB from 1969 to 2012, Manuel Solà-Morales oversaw the pivotal reform of urban pedagogy in the Barcelona school. Determined to overcome the technocratic tendency that marked Spanish architecture and planning in the final decade of Franco’s regime, Solà-Morales’ mission was to educate what he defined as the ‘architect-urbanist’ through a foundational program that unified architecture and studies of urban form as a single discipline. Under the aegis of urban morphology, the new course of Urbanística taught by LUB’s team instituted the study of the city and its history as the primary ground for every architectural and urban project.

Een groeiende nadruk op de activering van uitkeringsgerechtigden heeft in veel Westerse verzorgingsstaten geleid tot de ontwikkeling van interventies die gericht zijn op uitkeringsgerechtigden met gezondheidsklachten. Vormen van dwang, zoals verplichte participatie, worden meer en meer toegepast binnen dit activeringsbeleid. Een voorbeeld hiervan is het Nederlandse project “Gezond aan de Slag”, dat een interventie ontwikkelde en evalueerde waarin een fysiek trainingsprogramma gecombineerd wordt met cognitieve training. Hoewel HtW als “best practice” gold, liet een randomized trial geen positieve effecten van de interventie zien. Omdat het cognitieve trainingsprogramma, gebaseerd op rationeel-emotieve therapie, niet eerder afzonderlijk werd bestudeerd, werd een diepgaande kwalitatieve studie uitgevoerd. Getracht werd om de oorzaken van het falen van het programma in kaart te brengen. Zes, gericht geselecteerde, trainers werden geïnterviewd. De resultaten lieten zien dat de trainers problemen hadden met de heterogeniteit van de deelnemersgroep en op andere problemen, verwachtingen en arbeidsmarktobstakels stuitten dan vooraf verwacht. De verplichte aard van HtW had een negatief effect op de motivatie van zowel deelnemers als trainers. In de discussieparagraaf van dit artikel worden vraagtekens geplaatst bij de veronderstelling dat de coping stijl en cognities van uitkeringsgerechtigden met gezondheidsproblemen de belangrijkste hindernissen zijn voor het vinden van werk, en worden vraagtekens geplaatst bij het beleid om fysieke beperkingen van deelnemers te negeren. De auteurs suggereren dat met betrekking tot dit complexe praktijkprobleem, verbetering kan worden bereikt door aanpassen en leren van de interventie gedurende de toepassing daarvan toe te staan, en door expliciet te reflecteren op de normatieve aspecten van de interventie, en de perspectieven van de uitkeringsgerechtigden zelf.

At the request of ten political parties, the Netherlands Bureau for Economic Policy Analysis (CPB) and PBL Netherlands Environmental Assessment Agency have mapped out the effects of the respective election platforms on the economy and the environment. The analysis shows that each of the proposed policy measures included in the platforms has both advantages and disadvantages. The platforms thus reflect the diverse choices that have been made by the parties. The publication presents the impact of party programs on public finances, purchasing power and employment. Also included in the publication are analyses in the field of mobility, energy and climate, nature, education, housing and healthcare [Dutch] De verkiezingsprogramma's 2012 laten zien welke keuzes politieke partijen maken voor de jaren 2013-2017.

ENEA (Italian National Agency for New Technologies, Energy and the Environment) is conducting a large research and development programme on innovative vehicles with high energy efficiency and low environmental impact. In particular conducts activities on electric and hybrid vehicles. Testing and evaluation activities play a strong role in this programme. A complete characterization chain has been then defined and set up with a network of facilities which covers main testing needs for single components, subsystems and complete vehicles, in simulated and real operating conditions. The test facility which has been realised is able to experiment and fully characterise complete drive-trains (and subsystems) for pure electric and hybrid vehicles. It is composed by a different section for each subsystem: 1) power generation; 2) energy storage and management; 3) driving motors. Each section acts as an experimental island, able to operate alone or jointly with the other sections. In fact, all the sections are remotely controlled and managed in order to create different assembly of the drive-train. The facility has been sized to allow the testing of drive-trains and subsystems of small and medium-sized vehicles (up to minibuses), but an extension to larger vehicles is possible. During 1996 and part of 1997 the Drive train Test Facility has been completed and made operative. This paper mainly presents the final configurations of these novel testing systems with peculiar features and characteristics.

I feel that the changes which have taken place in science in the last few years open up new possibilities, about which I should like to say a few words. In 1951 we began work on thermonuclear reactions in the confident belief that we would solve the problem with a rush and immediately. I was assigned the task of ensuring that our future thermonuclear reactor would not get too much out of hand. It was like the story of the man who wished to invent a perpetual motion machine and had taken out a patent on a method for keeping it under control. This attitude stemmed from the successes in developing ''explosive thermonuclear reactors'', a task which was achieved within a very short period of time, leaving physicists with the impression that they could do everything - and do it fast. However, experience soon showed that here we had a scientific rather than a technological problem and that it would be necessary to study in detail the physics of plasmas - which we have now been doing for over ten years. [Russian] Mne kazhetsja, chto za poslednie gody- v nauke proizoshli izmenenija, otkryvshie novye vozmozhnosti, na kotoryh ja hotel by ostanovit'sja.

Mne bylo porucheno obespechivat' regulirovanie budushhego termojadernogo reaktora, chtoby tot ne ochen' ''razognalsja'' i ne vyshel iz-pod kontrolja.

Bol'shie uspehi v razrabotke ''vzryvchatyh termojadernyh reaktorov'', kotorye byli sozdany za ochen' korotkoe vremja, porodili u fizikov uverennost' v to, chto oni mogut sdelat' vse i sdelat' bystro.

L'INAF-OA Cagliari (OACa) sta sviluppando un ricevitore criogenico a basso rumore basato su un mixer SSB (Single Side Band) a superconduttore SIS (Superconductor-Insulator-Superconductor) per la banda 3 mm. Il ricevitore, acquistato da IRAM, è stato fortemente modificato per essere adattato al fuoco Gregoriano di SRT (Sardinia Radio Telescope). Lo strumento è caratterizzato da una nuova criogenia a ciclo chiuso 4 K (per evitare l'uso di elio liquido in antenna), da un nuovo oscillatore locale (di tipo ALMA Banda 3) e da un nuovo sistema di controllo e di monitoraggio basato su schede Raspberry ed Arduino sviluppato ad OACa. Verranno presentati i recenti sviluppi sul ricevitore, inclusi i risultati preliminari della misura della temperatura di rumore, che raggiunge un valore pari a Trec=66 K alla frequenza di 86 GHz, nonostante la criogenia non sia ancora ottimizzata. L'INAF-OACa è coinvolto nel progetto AETHRA (Advanced European Technologies for Heterodyne Receivers for Astronomy) nel quadro del programma Radionet/Horizon2020 per il quale sta contribuendo al WP1 (Work Package 1). Lo scopo del WP1 è di sviluppare e costruire un dimostratore di un array di ricevitori a doppia polarizzazione per la banda 3 mm basato su amplificatori criogenici a basso rumore (LNA) in tecnologia a semiconduttore MMIC. Nell'ambito del WP1 l'OACa ha in carico il progetto di un OrthomodeTransducer (OMT) in guida d'onda o in tecnologia planare per la banda 72-116 GHz che sia integrabile con amplificatori MMICs ed adatto all'integrazione in un array da installare nel piano focale di un radiotelescopio. Verranno presentati i design preliminari degli OMT per AETHRA, che sono basati su prototipi sviluppati in passato da OACa.

L’articolo, a partire da queste prime indicazioni, affronta, attraverso l’analisi della rivista ufficiale dell’OIM «Mouseion»,  il tema dello sviluppo delle attività sociali e educative promosse dall’Office e declinate nei principali paesi membri della Società delle Nazioni fino al 1939, anno in cui si sarebbe dovuto svolgere un convegno internazionale sul tema, i cui risultati avrebbero dovuto costituire il terzo volume degli atti di Muséographie. Il convegno, di cui vengono qui riferiti proposte e programmi, non venne mai realizzato a causa dello scoppio della seconda guerra mondiale.   In 1927, the committee of experts convened to study the program of the Office International des Musées (OIM, established the previous year, had adopted a number of resolutions relating to the organization of the institution, cataloging and social role of the modern museum was increasingly called upon to perform. The paper, based on these early indications, addresses through the analysis of the official magazine «Mouseion» the issue of the development of educational and social activities promoted by the OIM and declined in the major member countries of the League of Nations until 1939, the year in which would have to play an international conference on whose acts would have to be the third volume of Muséographie. The conference, which we outline here the proposals and programs, was never realized due to the outbreak of the World War II.

Energy conservation in the existing Dutch private housing stock; Energiebesparing bestaande koopwoningen

One of the elements of the 'SER energy agreement' concluded by the Netherlands Social and Economic Council (SER) is concerned with energy efficiency in the current private housing stock. Over the past few decades there have been many programmes in this area, and a number of measures have certainly been implemented. To say that these have been overwhelmingly successful in securing the Dutch government's climate policy targets for the built environment would be an exaggeration, though. The pace of change has been too slow. The Netherlands Society for Nature and Environment (Natuur en Milieu) asked CE Delft to estimate the impact of a package of measures for improving the energy performance of existing dwellings, comprising incentives up to the year 2020 and an obligatory label C or better thereafter. The data in this brief report are derived largely from the dashboard model 'New instruments for the existing housing stock' developed by CE Delft in collaboration with ECN [Dutch] In het SER-energieakkoord speelt energiebesparing in de bestaande woningbouw een relevante rol. Vele programma's zijn de afgelopen decennia de revue gepasseerd, waarbij zeker besparingsmaatregelen zijn getroffen. Er is echter geen sprake van doorslaggevend succes dat de klimaatdoelen van de Rijksoverheid in de gebouwde omgeving daadwerkelijk binnen bereik brengt. Meer tempo is nodig. Natuur en Milieu heeft CE Delft gevraagd om de effecten in beeld te brengen van een pakket voor de verbetering van de energiekwaliteit van bestaande woningen dat bestaat uit verleiden tot 2020, met na 2020 een verplichting tot label C of beter. De cijfers in deze notitie zijn in belangrijke mate ontleend aan het dashboardmodel 'Nieuwe instrumenten voor de bestaande bouw' van CE Delft dat is ontwikkeld in samenwerking met ECN.

The work deals with a detection system qualification for direct measurements of thyroid internal contamination by radioiodine. The isotopes {sup 131}I and {sup 125}I are the most frequently used in nuclear medicine. Because of their volatility they are very dangerous for thyroid contamination by inhalation. The system has been projected to be easily and fast used and above all transportable where the control is necessary. These characteristic make it able to realise supervision programs of internal contamination by radioiodine. In fact due the very high control frequencies (each 15 days for {sup 131}I), these programs are usually very expensive and demanding when they are executed in external measurement laboratories. The following steps are described: devices presentation, calculation of energy and efficiency parameters, minimum detectable activity, time system reliability, best operative conditions in the measurements. At the end an application example of the system is reported. [Italian] Il presente lavoro consiste nella qualificazione di un sistema di rivelazione per misure dirette di contaminazione interna da radioiodio in tiroide, progettato per essere maneggevole, di semplice e rapido impiego e trasportabile sul luogo dove e' richiesta la misura. Il sistema e' stato studiato per la realizzazione di programmi di sorveglianza della contaminazione interna da radioiodio che, richiedendo frequenze di controllo elevate (quindicinali per lo {sup 131}I), sono estremamente impegnativi ed onerosi, soprattutto se i controlli vengono effettuati in centri di misura esterni. Dopo la determinazione dei parametri della calibrazione in energia ed efficienza, la minima attivita' rivelabile, l'affidabilita' del sistema nel tempo e le condizioni operative ottimali da adottare in sede di misura, viene verificata la piena affidabilita' del sistema in un programma di sorveglianza della contaminazione interna da radioiodio.

Full Text Available Gathering Stories along the Front: A Critical Look at Ten Oorlog [To War]This article reflects critically on the popular television programme Ten Oorlog, thereby examining the field of tension between history and entertainment, between historians and ‘the public’. History can be addressed via various television formats as an historical documentary or a travel programme. An analysis indicates the extent to which Ten Oorlog is inspired by these formats. However, the popular television programme from the outset was not conceived as a classic historical documentary and perhaps can best be described as a historical human interest programme as part of the large-scale commemoration of the First World War. How do history and entertainment relate to one another in this programme? Is there more emphasis on the historical context or on anecdotal stories? This analysis of Ten Oorlog illustrates the tense relation between historians and ‘the public’.Dit artikel werpt een kritische blik op het populaire televisieprogramma Ten Oorlog en gaat daarbij in op het spanningsveld tussen geschiedenis en entertainment, tussen historici en ‘het publiek’. Geschiedenis kan via verschillende formats zoals een historische documentaire of een reisprogramma aan bod komen op televisie. Een analyse van deze formats geeft aan in welke mate Ten Oorlog hierop geïnspireerd is. Het populaire televisieprogramma was echter van begin af aan niet als een klassieke historische documentaire bedoeld en kan misschien het bestomschreven worden als een historisch human interest programma, in het kader van de grootschalige herdenking van de Eerste Wereldoorlog. Hoe verhoudengeschiedenis en entertainment zich daarin? Helt de balans meer over naar historische omkadering of naar anekdotische verhalen?

In the frame of the program of the Institute for Radiation Protection of ENEA, related to the evaluation of dose from radon and thoron progeny, an alpha spectrometer for the continuous air monitoring (CAM type) of radon and thoron has been realized. The constructive characteristics of the device are here presented together with energy and efficiency calibration. The device allows, by means of a screen type diffusion battery and a filter, to determinate the single radioactivity of each radionuclide of the progeny selecting them in relation to their diffusive behaviour (dichotomous particle size selection). The three-count filter method has been employed to measure the concentrations of {sup 218}Po, {sup 214}Pb and {sup 214}Bi in air. Radon and thoron effective doses using a dosimetric, instead of an epidemiologic approach, will be then evaluated. [Italian] Presso l'Istituto per la Radioprotezione, nell'ambito del programma di valutazione di dose da radon e' stato progettato e realizzato uno spettrometro alfa per il monitoraggio continuo in aria (CAM) della progenie del radon e del toron.

E' stato inoltre applicato un metodo spettrometrico a tre conteggi per il calcolo delle concentrazioni individuali della progenie del radon, {sup 218}Po, {sup 214}Pb and {sup 214}Bi, effettuando un conteggio alfa di {sup 218}Po e due conteggi alfa di {sup 214}Po.

The second version of the program GAPHAT (Outlined Analysis Program Horizontal Axis Wind Turbines) is discussed. The program can be used for investigated analysis and gives the following results: 1. aerodynamical coefficients as functions of high-speed, blade angle and rotor azimuth angle; 2. loads in the heart of the blade and on the rotor axis as function of the time; 3. dynamic behavior at different adjustments. The aerodynamic loads follow a combination of linear momentum theory and blade element theory. The resulting equations are calculated with a quadratic equation with the inflow angle as an unknown. Summation of aerodynamic, innate weight and centrifugal loads gives the total loads. For the blade angle control a few general models were developed: an active on/off control for power and a PID control for linear speed (PID is proportional, integral and differential control). Calculations of aerodynamic coefficients and of loads in the heart of the blade were compared to calculations with the program PHATAS-I. The differences are less than 10% in most cases. 16 figs., 7 refs., 1 tab

Broad band seismology in the Scotia region. The base Esperanza seismological observatory

1995-08-01

The lithospheric study and the identification of relevant lateral heterogeneities in the Antarctic continent and borderlands, is essential to understand the geodynamic evolution both of the continental and oceanic bordering regions. The complexity of the geological evolution and the structural properties of the lithosphere in the Scotia area have been stressed by many authors. The present setting of the area is the result of the mutual interaction among the Antarctic, South American and several minor plants whose geodynamic history and actual boundaries are still partially unknown. The intense seismic activity that characterizes the region encourages the use of the seismological approach to investigate the lithospheric structure of the area. Since January 1992 a broad band three components station is operating at the Antarctic base Esperanza in the NE area of Antarctic Peninsula. The station has been installed with financial support of the Italian Programma Nazionale di Ricerche in Antartide (PNRA) by Osservatorio Geofisico Sperimentale (OGS) and Instituto Antartico Argentino (IAA). Russi et al. (1994) have analyzed selected recordings using the frequency-time analysis (FTAN) method obtaining some relevant information on the large scale structure of the lithosphere in the Scotia region even if data recorded by a single station were available. The extension of our analysis to further events and to horizontal component records is here presented. Within the framework of the international co-operation to the Antarctic Seismographic Network, the OGS and the IAA are upgrading the Esperanza station and installing an additional broad band station near the town of Ushuaia (Tierra del Fuego, Argentina) with the financial support of PNRA. The inversion of the dispersion curves through the FTAN of the signals recorded by an increased number of stations and generated by events with source-station paths spanning the region will allow us to extract the elastic and anelastic

Questa sessione apre i lavori dell’VIII Conferenza di Sanità Pubblica della nostra Società. Il programma che vi è stato presentato, la sede in cui si svolge, la qualità e la dimensione della vostra partecipazione riconfermano la validità di una formula che si è andata consolidando nel tempo e rappresenta ormai, insieme al Congresso Nazionale biennale, il fiore all’occhiello della ricchissima attività convegnistica della SItI.

Si conferma anche la straordinaria continuità e coerenza della nostra società scientifica nell’interpretare, a livelli qualitativi sempre più elevati, la propria missione di individuazione, approfondimento e disseminazione della conoscenza necessaria per migliorare l’azione di Sanità Pubblica nel nostro Paese.

La sessione testimonia questa attenzione! Con il tema della SARS, la Relazione di Pietro Crovari dà conto delle linee di comportamento dell’apparato di sanità pubblica nell’affrontare un problema che ha scosso l’opinione pubblica mondiale risvegliando anche nei paesi più progrediti antiche paure e arcaici pregiudizi; che ha provocato contraccolpi enormi in ambito commerciale ed economico; che ha richiamato l’attenzione su regole e precauzioni tanto scontate da risultare poi in pratica quasi inapplicate. La risposta italiana è stata corretta, impostata sulle conoscenze scientifiche adottate con pragmatico buon senso. Una autorevole presenza della cultura igienistica nelle sedi decisionali ci consente anche di guardare con serenità ai possibili rischi ancora ipotizzabili.

La partecipazione alla Comunità Europea e l’adesione ai suoi principi e le sue regole stanno producendo una serie di cambiamenti che arriveranno a incidere anche sui nostri modelli di prevenzione. La Relazione di Vittorio Carreri fornirà il punto di vista di uno sperimentato ed attento conoscitore della materia riguardo agli innumerevoli problemi già aperti e su quelli ancora incombenti sul

Obiettivi: obiettivo dello studio è verificare il miglioramento della qualità delle indagini epidemiologiche per eventi epidemici di tossinfezione alimentare dopo l’implementazione di un protocollo aziendale condiviso tra i servizi del Dipartimento di Prevenzione della ASL RMG (SIP-SIAN-SV e l’attivazione della pronta disponibilità di una equipe dedicata.

Metodi: sono state presi in considerazione tutti gli eventi epidemici di tossinfezione alimentare individuati dal SIP nel periodo 1998-2002: il periodo A (1998-1sem2000 è quello precedente all’attivazione del protocollo e il periodo B (2sem 2000-2002 è quello successivo. È stato realizzato un questionario per la raccolta retrospettiva dei dati archiviati; l’informatizzazione è stata effettuata con il programma EPIinfo vers. 6.0 e l’analisi con il software microsoft excel vers 7.0. Risultati: nel periodo A sono stati individuati n.14 eventi epidemici per un totale di 76 malati. Il servizio SIAN e/o SV è stato attivato nel 28% dei casi, il sopralluogo nel luogo di consumo del pasto è stato effettuato nel 42%(6/14 e nel 33% dei casi il campionamento dell’alimento ha individuato l’agente microbiologico. Nel periodo B invece sono stati individuati n.21 eventi epidemici per un totale di 202 malati. Il servizio SIAN e/o SV è stato attivato nel 71% dei casi, il sopralluogo nel luogo di consumo del pasto è stato effettuato nel 57%(12/21 e nel 57% dei casi il campionamento dell’alimento ha individuato l’agente microbiologico.

Conclusioni: in seguito all’attivazione del protocollo è migliorata la qualità dei dati raccolti. L’istituzione di una equipe dedicata ha determinato una più accurata sorveglianza degli episodi di tossinfezione attraverso una maggiore efficienza nell’attivazione dei servizi SIAN-SV. Questa esperienza dimostra che l’integrazione tra i Servizi del Dipartimento di Prevenzione

Obiettivi: l’interesse suscitato dall’obesità in età scolare è in continuo aumento, sia a causa della prevalenza sempre più estesa di tale patologia in questa età, sia perché il bambino vive con ansia e ostilità questo suo stato divenendo spesso oggetto di derisione da parte del gruppo. In un progetto di educazione alimentare che potesse avere un’azione di prevenzione primaria nei riguardi dell’obesità in età evolutiva; il nostro obiettivo è stato quello di effettuare uno screening prima di iniziare l’intervento su una porzione di popolazione scolastica per valutare lo stato auxologico dei soggetti e saggiare le loro conoscenze sulla nutrizione e sulle abitudini alimentari. Abbiamo ritenuto che ormai sia assolutamente necessario ricavare queste informazioni per poi programmare interventi efficaci ed efficienti per migliorare la qualità di ogni programma di educazione alimentare.

Materiali e metodi: l’indagine condotta in tre scuole elementari di Palermo ha coinvolto per ogni scuola due terze, due quarte, due quinte per un totale di 360 bambini con un’età compresa tra i 7 e gli 11 anni. Per la valutazione auxologica sono stati presi in considerazione statura, peso ed età cronologica secondo il metodo di J.M. Tanner. Il rilevamento delle abitudini alimentari e stili di vita è stato effettuato per mezzo di un questionario a risposta multipla.

Risultati: dai risultati di questa indagine preliminare è emerso che la prevalenza dell’obesità in età evolutiva nella nostra popolazione si avvicina notevolmente a quella italiana che è del 19%. Lo stile di vita sedentario aggrava la già precaria situazione dovuta alla cattiva alimentazione.

Conclusioni: dalle considerazioni fatte appare evidente quanto sia necessario e urgente un intervento efficiente di educazione alimentare che non resti sporadico e privo di una metodologia ben

Full Text Available È ormai opinione largamente condivisa che l’attuale “crisi” dell’organismo territoriale non sia soltanto economica ma anche ambientale. Quest’ultima tematica unita a quella della green economy potrebbero rappresentare l'occasione di intervenire sui sistemi territoriali non urbani, un tempo vitali per l’economia locale, ed oggi abbandonati a se stessi a favore delle aree urbanizzate, luoghi economicamente più vantaggiosi. Partendo dalle indicazioni del Programma per l’Ambiente delle Nazioni Unite (UNEP si potrebbero definire politiche di sviluppo al fine di migliorare la competitività e l'attrattività dei sistemi territoriali rurali attraverso la valorizzazione delle risorse endogene presenti su tali territori, con l’obiettivo di favorire lo sviluppo ecosostenibile delle diverse attività al fine di creare una rete integrata. La ricerca svolta presenta le diverse dinamiche legate alla creazione di una rete di Eco-Villaggi, con lo scopo di rifunzionalizzare il patrimonio edilizio e urbanistico esistente, migliorando, così, la qualità della vita dei centri montani. Questo modello può rappresentare concretamente una delle possibili soluzioni allo spopolamento, nel conservare e tutelare lo spazio naturale attraverso la promozione della green economy, basata sull’utilizzo di sistemi di produzione sostenibili, nel rispetto dei requisiti ambientali, nell’attivazione di sistemi energetici rinnovabili e nel richiamo turistico del patrimonio storico-culturale della montagna. Infatti queste risorse se gestite nel modo corretto, attraverso una attenta pianificazione territoriale, potrebbero rappresentare il volano per un modello di sviluppo sostenibile e allo stesso tempo potrebbero avviare una riqualificazione e valorizzazione dei borghi rurali, che spesso ospitano un patrimonio architettonico di notevole pregio. Risulta necessario, per i contesti rurali, porre in atto strumenti, modalità e forme innovative d’intervento capaci

After the start of the natural gas exploitation on the Dutch island Ameland in 1986 surveys were carried out from 1988 on to investigate and monitor the effect of the exploitation on land subsidence and related environmental effects. In this third report evaluated results of that survey over the last 18 years are presented and discussed. [Dutch] De gaswinning op Ameland-Oost is begonnen in 1986. In dat zelfde jaar werd in opdracht van de NAM door WL|Delft Hydraulics in samenwerking met Alterra (toen RIN) een voorspelling gemaakt van de mogelijke effecten van de bodemdaling, waarna eind 1988 is begonnen met de monitoring. De eerste twee rapportages zijn gebaseerd op gegevens tot 1994 respectievelijk 1999 en beschrijven de effecten over een periode van 8 jaar respectievelijk 13 jaar na het begin van de gaswinning. Deze derde rapportage is gebaseerd op gegevens tot 2003/2004. Voor meer achtergrondinformatie wordt verwezen naar het evaluatierapport van maart 2000 en het nieuwe monitoringsprogramma 2000-2010 die op de bijgevoegde CD aanwezig zijn. De bodemdaling vond plaats in de vorm van een grote schotel met een doorsnede van ongeveer 15 km, en werd meetbaar vanaf 1987. In de periode daarna, ongeveer tot het jaar 2000, daalde de bodem in het centrum van de schotel met ongeveer 1,8 cm per jaar. Daarna begon de dalingssnelheid wat af te nemen, door de daling van de druk in het veld, tot circa 1,2 cm per jaar. In 2003 bedroeg de bodemdaling in het centrum van de bodemdalingschotel 27 cm. Verwacht wordt dat de bodemdaling steeds verder af zal nemen totdat hij rond het jaar 2020 geheel beeindigd zal zijn. In 2000 zijn de resultaten gepresenteerd in een openbaar debat. Sindsdien zijn verschillende verbeteringen doorgevoerd. De highlights van de afgelopen 5 jaar zijn de publicatie van het onderzoeksprogramma 2000-2010, het vogelonderzoek, de uitgebreide metingen op de wadplaten en de nieuw ontwikkelde techniek van spijkermetingen. Daarnaast heeft het nieuwe programma voor de

Surface water (CLIMA) Project of the Programma Nazionale di Ricerca in Antartide activities. Dissolved oxygen, nutrients, phytoplankton pigments and concentration and complexation of dissolved trace metals were determined. Experimental data were elaborated by Principal Component Analysis (PCA). As a result of solar heating and freshwater inputs from melting sea-ice, the water column was strongly stratified with an Upper Mixed Layer 4-16 m deep. The integrated Chl a in the layer 0-100 m ranged from 60 mg m-2 to 235 mg m-2, with a mean value of 138 mg m-2. The pigment analysis showed that diatoms dominated the phytoplankton assemblage. Major nutrients were generally high, with the lowest concentration at the surface and they were never fully depleted. The Si:N drawdown ratio was close to the expected value of 1 for Fe-replete diatoms. We evaluated both the total and the labile dissolved fraction of Fe and Cu. The labile fraction was operationally defined by employing the chelating resin Chelex-100, which retains free and loosely bound trace metal species. The total dissolved Fe ranged from 0.48 to 3.02 nM, while the total dissolved Cu from 3.68 to 6.84 nM. The dissolved labile Fe ranged from below the detection limit (0.15 nM) to 1.22 nM, and the dissolved labile Cu from 0.31 to 1.59 nM, respectively. The labile fractions measured at 20 m were significantly lower than values in 40-100 m samples. As two stations were re-sampled 5 days later, we evaluated the short-term variability of the physical and biogeochemical properties. In particular, in a re-sampled station at 20 m, the total dissolved Fe increased and the total dissolved Cu decreased, while their labile fraction was relatively steady. As a result of the increase in total Fe, the percentage of the labile Fe decreased. An increase of the Si:N, Si:P and Si:FUCO ratios was measured also in the re-sampled station. On this basis, we speculated that a switch from a Fe-replete to a Fe-deplete condition was occurring.

This report describes the results of the final phase of a research project about local climate policy. An ideal model of a climate management system was tested by practise for the municipality of Alkmaar. In this case study ECN analysed numerous policy documents as well as the process of building a new soccer stadium. We looked if the municipal organisation passed through all the steps of this climate management system and if it used any mechanisms through which the external integration of climate policy in policies other than environmental policy fields could be enhanced. The report shows that though the model was not running effectively in Alkmaar, the municipal organisation still managed to partly integrate climate policy in non-environment policy areas. For the major part this can be contributed to enthusiastic and hard-working sustainability coordinators. Had the systematic approach been in place, the municipality would clearly be more accurate in its network policy steering which proved necessary to realise the new soccer stadium. [Dutch] Dit rapport doet verslag van een onderzoek naar lokaal klimaatbeleid in Alkmaar. Het onderzoek heeft plaatsgevonden in de eerste maanden van 2001. Het is onderdeel van het onderzoeksproject 'Lokale overheden en klimaatbeleid' dat is uitgevoerd in opdracht van het Nationaal Onderzoek Programma Mondiale Luchtverontreiniging en Klimaatverandering (NOP-MLK). Doelstelling van het onderzoek is te analyseren in hoeverre er in de dagelijkse Alkmaarse beleidspraktijk sprake is van integraal klimaatbeleid. Daartoe is er een analyse gemaakt van beleidsdocumenten en het proces rond de bouw van het nieuwe AZ-voetbalstadion. De conclusies hebben betrekking op de stand van zaken op het moment van onderzoek. In de periode tussen onderzoek en publicatie is veel gebeurd. Zo is Alkmaar sterk betrokken bij afspraken voor CO2- reductie met de provincie, bij het CO2- servicepunt en bij het bovengenoemde klimaatconvenant. De conclusies

In 1991, 1.1 thousand million footwears have been produced in the European Union. Italy is the most important manufacturing pole with 411 million pairs produced. In Italy, the region Marche holds the manufacture supremacy (provinces of Macerata and Ascoli Piceno) with a production share of 27 {+-} 5 %; that means about 89-129 million pairs produced in 1999 and about 38.000 workers employed. During a research program ordered by the region Marche to the Diffusion Centre of the Environmental Culture and Technology, Urbino University of Studies, the VOC emission factors relevant to footwears manufacture cycle (except those of soles manufacture) have been assessed. The assessment was carried on the basis of emissions in the atmosphere, on basis of industrial accounting data directly acquired among a shoe-factories sample, and on basis of a wide statistic sample of technical reports according emissions local regulations. Such results may be useful both for the drawing up of guidelines for the emissions authorizations and as fundamental components of LCA (Life Cycle Analysis) footwear inventories.

both would seem to be valuable as means for making tacit knowledge explicit, and have the potential for solidifying, substantiating and transferring it. This is because they would act as guiding principles to provide direction for methodological action by social professionals in contact with the target group. They exist alongside each other and can be deployed according to the situation, goals, persons and resources available for the range of working methods, target groups, goals and contexts. SAMENVATTINGDe ontwikkeling van een met onderzoek onderbouwde methodiek voor het meidenwerkDit artikel doet verslag van een zoektocht naar de mogelijkheden voor het ontwikkelen van een met onderzoek onderbouwde methodiek voor het meidenwerk. Het geeft inzicht in de mogelijkheden en moeilijkheden voor het opbouwen van een kennisbasis voor open benaderingswijzen in de praktijk van het sociaal werk. De aanleiding is het verzoek van Amsterdamse meidenwerkers om hulp bij het ontwikkelen van een met onderzoek onderbouwde methodiek voor een bijna 90-jarige diverse en dynamische praktijk. De achtergrond vormt de discussie over de kennisbasis van het sociaal werk. Gangbare modellen als “evidence-based practice”, “practice-based evidence” en “common factors” worden besproken op geschiktheid voor het ontwikkelen van een met onderzoek onderbouwde methodiek voor open benaderingswijzen, waarna programma evaluatie als mogelijk alternatief wordt uitgediept. De conclusie is dat er vooral met betrekking tot open benaderingswijzen binnen het sociaal werk dringend meer aandacht nodig is voor het proces van methodiekontwikkeling en de wijze van onderbouwing. De eerste ervaringen met programma evaluatie en het daaruit voortvloeiende model van methodische principes zijn voorzichtig positief. Programma evaluatie lijkt handreikingen te bieden voor het omgaan met het spanningsveld tussen de wetenschappelijke kwaliteit van de bevindingen en de bruikbaarheid voor de praktijk. Methodische

At the request of nine political parties, CPB Netherlands Bureau for Economic Policy Analysis and PBL Netherlands Environmental Assessment Agency have mapped out the effects of the respective election platforms on the economy and the environment. The analysis shows that each of the proposed policy measures included in the platforms has both advantages and disadvantages. The platforms thus reflect the diverse choices that have been made by the parties. The publication presents the impact of party programs on public finances, purchasing power and employment. Also included in the publication are analyses in the field of mobility, energy and climate, nature, education, housing and healthcare. [Dutch] Op verzoek van politieke partijen maakt het CPB voorafgaand aan de verkiezingen traditiegetrouw een analyse van de economische effecten van verkiezingsprogramma's. Negen partijen (CDA, PvdA, SP, VVD, PVV, GroenLinks, ChristenUnie, D66, SGP) hebben het CPB gevraagd om de economische effecten van hun programma te analyseren. Deze keer zijn er ook effecten op milieu, natuur en bereikbaarheid geanalyseerd. Het Planbureau voor de Leefomgeving (PBL) heeft deze analyse voor zijn rekening genomen. Op verzoek van het PBL heeft het Energieonderzoek Centrum Nederland (ECN) een substantiele bijdrage geleverd aan de analyse van de energie- en klimaat-maatregelen. Deze editie van Keuzes in Kaart verschaft allereerst een analyse van de effecten die de diverse verkiezingsprogramma's hebben op de overheidsfinancien in de volgende kabinetsperiode en op lange termijn. Ook worden de gemiddelde inkomenseffecten en de werkgelegenheidseffecten op lange termijn in kaart gebracht. Daarnaast analyseren de planbureaus de effecten op een aantal specifieke terreinen: bereikbaarheid; klimaat en energie; landbouw, natuur en landschap; onderwijs en innovatie; woningmarkt; zorg. De opzet van deze publicatie is als volgt. Hoofdstuk 1 schetst de achtergonden en aanpak. Hoofdstuk 2 geeft een

Within the framework of the IPL (Innovation Program Air Quality) a series of studies and experiments were performed focusing on the effect that the road surface can have on the environmental quality of the air at the side of the road and what potential benefits can be found in a specific treatment of the road surface. The overall impression we get, when evaluating the different research reports, is the widely varying opinions and research results about the contribution of road and tyre wear related particles to the overall PM10 emission of road traffic. A similar lack of common understanding was experienced when studying the different opinions and experimental data related to the effect of the road surface type on road and tyre wear particles. Part of the scatter in opinions and data can be explained by the relative magnitude of the measuring errors in relation to the studied effects. Namely, the road related contribution is already a smaller part of the total PM10 concentration. Next the part related to wear is the smaller part of the road contribution and in this part the effect of a road surface is to be investigated with measuring equipment and under conditions whose accuracy and variation already are in the order of the expected effect. [Dutch] In het kader van het IPL-programma zijn, in de oplossingsrichting wegdekeffecten, op een groot aantal deelgebieden onderzoeken uitgevoerd. De focus van de onderzoeken was deels gericht op het verkrijgen van een beter begrip van de rol van het wegdek in het ontstaan en de overdracht van fijn stof, deels gericht op maatregelen op of aan het wegdek om de emissie of overdracht terug te brengen. Ten aanzien van de inzichten in de bron blijkt dat er uiteenlopende visies bestaan omtrent de relatieve bijdragen van band- en wegdekslijtage. Omtrent de overdracht naar de directe omgeving en de rol van het wegdek daarin bestaan nauwelijks gedeelde meningen. Het uitvoeren van full-size experimenten kent een serieuze beperking: er is

Personnel monitoring provides the means to measure and record the radiation doses received by individual workers. The ionising radiation decree (230/95) set out the circumstances when the assessment and recording of person's exposure is legally required. Many employers issue dosemeters to staff even though there is no legal requirement to do so. This may be part of a quality assurance programme or as a reassurance measure. Dosemeter readings will serve to ensure compliance with legal dose limits and assure the employer that radiation exposure is as low as reasonably achievable. The ENEA (National Agency for New Technology, Energy and the Environment) IRP (Institute for Radiation Protection) individual monitoring service has been running for over 30 years. It offers personnel dosemeters which are based on its expertise and backed up by continual research and development. The report provides details of the dosemeters in use at IRP enable to decide which ones most suit the needs and shows IMS's organisation, customer and communications, dose reports form and administrative items. A short mention of future development will also be given. [Italian] La dosimetria individuale fornisce gli strumenti per misurare e registrare le dosi da radiazioni ionizzanti ricevute dai lavoratori esposti. Il decreto legislativo 230/95 stabilisce le circostanze in cui il monitoraggio individuale e' legalmente richiesto. Molti datori di lavoro forniscono dosimetri individuali anche quando non vi e' una richiesta legale spesso per seguire le regole di un programma di assicurazione di qualita' relativo alla radioprotezione o per ottenere una conferma che il principio ALARA sia soddisfatto. Il servzio di dosimetria personale dell'Istituto per la Radioprotezione dell'ENEA e' attivo da oltre 30 anni e offre dosimetri sviluppati sulla propria esperienza nelle tecniche dosimetriche che vengono continuamente aggiornati e adeguati rispecchiando lo stato dell

Concordia (75°S 123°E) is a scientific base operated by French polar institute IPEV (Institut Paul-Emile Victor) and Italian Antarctic Program PNRA (Programma Nazionale di Ricerche in Antartide), and is located at Dome C, on the ice sheet of the East Antarctica plateau. It hosts a seismological observatory (CCD), which is jointly operated by EOST (Strasbourg) and INGV (Roma). The highly strategic location and remoteness is the key strength of our program, which has provided observatory quality data since 2000. The station has been integrated into the GEOSCOPE network in 2008 and the data are now available in real time through GEOSCOPE and IRIS. The observatory is located at distance of 1km from the base. The current installation is placed at a depth of 12m in an artificial vault constructed from two shipping containers and buried in the snow. The vault is thermally very stable, but the relatively close proximity to the base causes increased diurnal noise ( 40 dB) at frequencies above 1Hz, especially during the summer season. The uppermost 100 m thick firn (snow) layer forms a waveguide, where anthropic noise from the base is trapped and easily picked up by the seismometers (T240 and STS2). Another limitation comes from the hydrostatic pressure of the snow which is continuously deforming the metallic structures: we record container cracking events on the seismograms, and we see visual evidence of structural deformations inside the tunnel and the vault. We propose an evolution of the CCD station towards a post-hole installation. Placing a sensor at a depth of approximately 130 meters, will reduce noise from thermal effects, from tilting and from anthropogenic activity, because it would be located below the firn layer waveguide and the ice pinch-out depth. In order to operate the borehole station for several years, we intend to keep the hole open and the sensor accessible, while ensuring good coupling between the sensor and the surrounding hard ice. To achieve these

elevata risoluzione (HPIC) e del Conteggio a Scintillazione Liquida (LSC) su soluzioni ad elevato contenuto salino, e' stata eseguita utilizzando una soluzione sintetica di cemento contenente alcuni {beta}-emettitori che sono difficilmente rivelabili mediante tecniche di misura non-distruttive, insieme con altri radionuclidi importanti per la definizione dell'inventario radiologico nei rifiuti radioattivi. Dato che il lavoro richiedeva la manipolazione di soluzioni radioattive, e' stato progettato e realizzato un ambiente remoto in cui collocare l'apparato HPIC-LSC, in modo da operare in condizioni di sicurezza. Secondo quanto stabilito dal programma di ricerca, sono stati sviluppati e qualificati metodi analitici veloci per la separazione chimica e contemporanea rivelazione radiochimica degli elementi radioattivi di interesse. Dai risultati ottenuti, sono stati definiti alcuni protocolli di analisi che decrivono le condizioni operative dell'apparato HPIC-LSC, il loro campo di applicabilita', i limiti di rilevabilita' chimici e radiochimici.

Biomarkers for environmental and occupational exposure to aromatic mutagens and carcinogens from emissions of oil shale petrochemistry. Report of the EC PECO programme, project CIPA-CT92-3016

Oil shale processing for energy supply and further refining for petrochemistry is an important field of industry in Baltic countries. Estonia possesses the largest oil shale mines and oil shale processing plants of the world. Large scale oil shale extraction and processing lead to extensive environmental pollution and to the release of high levels of aromatic carcinogenic substances in processing plants. In the framework of the `PECO` programme, during 1993-1996, the European Commission funded a research project on biomarkers of environmental and occupational exposure in oil shale petrochemistry. The project gave the opportunity to develop and calibrate several biomarkers of exposure to aromatic carcinogens. The results obtained highlighted the role of blood benzene and urinary trans, trans-muconic acid and l-hydroxypyrene as sensitive biomarkers of occupational exposure to benzene and polycyclic aromatic hydrocarbons. A new promising approach was developed for the analysis of benzene adducts in haemoglobin. This methodology, as well as the {sup 32}P-postlabelling analysis of nulky adducts in DNA of blood cells of oil shale workers, showed high sensitivity and potential utility in human biomonitoring. Molecular cytogenetic methods based on in situ hybridization showed an exposure related clastogenic, and possibly an eugenic, effect in oil shale workers, demonstrating the potential advantage of new molecular approaches in the cytogenetic surveillance of carcinogen exposure. [Italiano] Gli scisti bituminosi costituiscono una materia prima di importanza prioritaria per l`industria petrolchimica dei paesi baltici. In Estonia, l`estrazione su larga scala degli scisti bituminosi ha prodotto una situazione di degrado ambientale, aggravata dalla emissione di considerevoli quantita` di sostanze cancerogene durante la lavorazione degli scisti negli impianti petrolchimici. Nell`ambito del programma di ricerca `PECO`, nel 1993-1996, l`Unione Europea ha finanziato un progetto

In the work, the life-cycle assessment approach is applied to the planning of waste management development in a seaside region (Piejūra) using the Waste Management Planning System (WAMPS) program. In Latvia, the measures to be taken for the climate change mitigation are of utmost importance - especially as related to the WM performance, since a disposal of biodegradable waste presents the primary source of GHG emissions. To reduce the amount of such waste is therefore one of the most significant goals in the State WM plan for 2013-2020, whose adoption is the greatest challenge for municipalities. The authors analyse seven models which involve widely employed biomass processing methods, are based on experimental data and intended for minimising the direct disposal of organic mass at the solid waste landfills. The numerical results obtained evidence that the thermal or biotechnological treatment of organic waste substantially reduces the negative environmental impact of WM practices - by up to 6% as compared with the currently existing.

Associazionismo industriale e corporativismo: l’American Chamber of Commerce in Italy nell’epoca fascista = Industrial association and corporatism: The American chamber of commerce in Italy during the fascism age

Full Text Available Il contributo in oggetto si propone di approfondire i rapporti tra le corporazioni e i gruppi industriali italiani da un’ottica particolare, quella dell’associazionismo che si concretizza con l’American Chamber of Commerce in Italy, instituita nel 1915 per agevolare le relazioni commerciali tra Italia e Stati Uniti. La grave crisi economica del 1930 e del 1931 e, poco dopo, le gravissime restrizioni portate agli scambi con l’estero dal programma autarchico del Governo fascista, influirono notevolmente sullo sviluppo della Camera. L’autorità dell’istituzione venne a diminuire, i rapporti con gli Stati Uniti si fecero più rari e il numero dei soci diminuì notevolmente. Alle corporazioni furono affidate le autorizzazioni sui nuovi impianti, la costituzione delle compagnie per la valorizzazione dell’Africa orientale italiana, il controllo sulle iniziative economiche nelle colonie, la collaborazione col fisco nella determinazione e nell’applicazione dei tributi ed infine il controllo sul commercio estero e sulle valute. Di conseguenza, la funzione che lo Stato avrebbe dovuto esercitare servendosi delle corporazioni finì col ricadere nelle mani dei grandi industriali, che le dominavano attraverso i loro rappresentanti. Da un lato, quindi, vi erano le corporazioni, che garantivano piena libertà ai gruppi industriali, avallandone le scelte; dall’altro lato, invece, vi erano le autorità governative che riconoscevano i limiti di competenza e d’intervento di quelle istituzioni e la necessità di una migliore definizione degli obiettivi. This contribution aims to examine the relationship between corporations and the Italian industrial groups from a particular perspective, which is that of associations through the American Chamber of Commerce in Italy, established in 1915 to facilitate the commercial relations between Italy and the United States. The economic crisis of 1930 and 1931 and, shortly after, the very serious restrictions

The Chinese government and trade and industry have the ambition to produce battery-electric vehicles on a large scale and to obtain a large market share worldwide. The policy of the Chinese government is characterized by three steps: stimulating R and D, showing the results and incentivising the market. Stimulating R and D has been done by the so-called 863 program over the last 15 years, focusing on battery-electric vehicles and on hybrid and fuel cell vehicles. Many car manufacturers pay attention to the development of electric vehicles, but they all focus mainly on conventional propulsion techniques. Interesting manufacturers are DongFeng, BAIC/Foton and BYD. Battery manufacturers also see opportunities in electric vehicles. Many are involved in the development of large batteries. BAK, BYD and Tianjin Lishen are the most interesting manufacturers. Various initiatives can be seen in the field of standardization, both nationally and internationally. Loading facilities are installed in an increasing number of locations. Despite all ambitions and initiatives it remains to be seen if China will cause a revolution. The available technical knowledge has its limitations. Investments and collaborations are limited. Moreover, the existing electrical infrastructure is preventing large-scale implementation of electric vehicles. China will play a role in the development of electric vehicles, but it will not cause a large acceleration.

If different methods of adequate sensitivity are available ICRP Publication 54, 'Individual Monitoring for Intakes-of Radionuclides by Workers: Design and Interpretations', recommends the use of direct measurements in individual monitoring for intakes of radionuclides. This report analyses the possibility to perform the different controls on the basis of the proposed Derived Reference Levels, respecting the accuracy requirement in evaluation of individual intake and dose. Therefore, general operative criteria are defined by analysing the potentialities and limitations of the different Whole Body Counters utilizable for the measurement with regard to the chemical, physical and metabolic characteristics of some radionuclides of particular interest in Radiation Protection. These criteria are useful for monitoring planning wherever a radiocontamination risk is possible. (author)

Le collezioni di Mammiferi del Museo Civico di Zoologia di Roma: una sintesi storica

Full Text Available Il Museo Civico di Zoologia di Roma è sorto nel 1932 all?interno del Giardino Zoologico dell?allora Governatorato di Roma, di cui ha condiviso la direzione tecnica ed amministrativa sino al 1998. Il nucleo centrale delle collezioni è costituito dal materiale di proprietà universitaria, di quello che fu il Museo di Zoologia della Regia Università, a sua volta diretto discendente delle collezioni del Museo di Zoologia ed Anatomia Comparata del Pontificio Archiginnasio Romano. La quasi totalità degli esemplari tassidermizzati risale al periodo in cui l?Istituto di Zoologia fu diretto da Antonio Carruccio (1883-1914. Dal 1932, la collezione teriologica si è andata arricchendo, in particolare di materiale osteologico, soprattutto con acquisizioni provenienti dal Giardino Zoologico e da rare spedizioni scientifiche, come quella organizzata dal CNR nell?Alto Rio Negro del 1962-3, guidata da Ettore Biocca. Anche a causa del fatto che per molti anni il Museo è stato privo di curatori, mancano importanti collezioni teriologiche da studio, fatta eccezione per quella cetologica. In molti casi, singoli esemplari potenzialmente di grande valore scientifico, mancano di dati esatti sulla località di cattura. Nell?ambito di un programma di ricatalogazione della collezione recentemente intrapreso, particolare attenzione è stata posta all?acquisizione di tutti i dati legati alla storia dei singoli esemplari, rintracciabili attraverso i resoconti di viaggio dei singoli esploratori. Nel periodo universitario, infatti, il Museo della nuova capitale d?Italia fu oggetto di grande attenzione da parte di privati ed enti, a partire dai Savoia, che donarono le loro collezioni o il materiale raccolto durante le spedizioni effettuate. Il lavoro di revisione in corso sta mettendo in luce una serie di esemplari meritevoli di ulteriori, dettagliate ricerche. È probabile che molto del materiale del Museo, pervenuto a Roma attraverso donazioni della famiglia reale

Tests for wholesomeness carried out in the United Kingdom as a part of the food irradiation programme are described. Both short-term animal feeding studies in rats, chickens and pigs, and long-term studies in rats and mice, have failed to demonstrate any adverse effects attributable to the consumption of irradiated food by the animals. The animal feeding tests have been designed with specific irradiation processes in mind, and all of these processes have involved the use of low, or moderate radiation doses. Thus, grain treated with 20 000 and 200.000 rad gamma radiation, and frozen egg (irradiated-to kill Salmonellae) treated with 0.5 and 1.0 Mrad have been tested by feeding to animals. Ham, irradiated with 250 000 rad to prolong its shelf life, has been tested, and also ham irradiated with 2 Mrad. Currently long-term studies are in progress to investigate the wholesomeness of fish treated with 0.6 Mrad (the maximum dose likely to be used to provide extended refrigerated (0 Degree-Sign - 4 Degree-Sign C) storage life). Short-term tests- have also been undertaken with potatoes (10000 rad) and horse flesh (0.65 Mrad). The nutritional quality of irradiated grain, egg, fish and some animal' feedings-stuffs has been investigated, using microbiological assay techniques. Losses in the B vitamins have been, found comparable with those reported by workers in the United States and are of the same order,of magnitude as losses occurring on heating, although differences were observed in the sensitivity of individual vitamins towards heat and irradiation. The losses in B vitamins occurring on irradiation and cpoking were found to be additive. No effects on the nutritional value of protein have been found. In 1962 the United Kingdom Ministry of Health set up a Working Party to review the effects of irradiation on food, and to report on the necessity-for official control. The report-pf the working party published in 1964, is discussed in relation to the wholesomeness tests carried out in the United-Kingdom. (author) [French] L'auteur decrit des examens de la comestibilite effectues au Royaume-Uni au titre du programme d'irradiation de produits alimentaires. Des etudes a court terme sur des rats, des poulets et des porcs, et des etudes a long terme sur des'rats et des souris n'ont permisse deceler aucun effet nuisible attribuable a la consommation par ces animaux.de nourritures irradiees. Les essais d'alimentation des animaux ont ete concus compte tenu de certains procedes,precis d'irradiation qui tous comportaient l'utilisation de doses d'irradiation faibles ou moderees. C'est ainsi que des. cereales traitees aux rayons gamma a 20 000.et 200 000 rad et des oeufs congeles (irradies pour detruire Salmonellae) traites a 0, 5 et 1 Mrad ont ete essayes. L'auteur a fait des essais avec du jambon irradie a 250 000 rad pour prolonger la duree de conservation et avec du jambon irradie a 2 Mrad. On procede, actuellement a des etudes a long terme, sur la comestibilite du poisson traite a 0,6.Mrad (dose maximale qui sera probablement utilisee pour augmenter la duree de conservation en refrigerateur (0 Degree-Sign / 4 Degree-Sign C)). L'auteur a egalement entrepris des essais a court terme sur les pommes de terre (10 000 rad) et la viande de cheval (0,65 Mrad). L'auteur a fait des recherches sur la qualite nutritive des cereales, des oeufs et.du poisson irradies et sur.quelques aliments pour animaux egalement irradies en reecurant a des procedes d'analyse microbiolo- gique. Il a constate que les pertes en vitamines B sont comparables a celles qu'ont indiquees des chercheurs des Etats-Unis et sont du meme ordre de grandeur que les pertes dues au traitement thermique bien que des differences aient ete observees dans la sensibilite de certaines vitamines a la chaleur et.aux rayonnements. Il a en outre constate que les pertes en vitamines B dues a l'irradiation et celles qui sont dues a la cuisson s'ajoutent. Il n'a constate aucun effet sur la valeur nutritive des proteines. En 1962, le Ministere de la sante publique du Royaume-Uni a cree un groupe de travail charge d'examiner les effets des rayonnements sur les produits alimentaires et de faire un rapport sur la necessite d'un controle officiel. L'auteur examine le rapport du groupe de travail, publie en 1964, en tenant compte ' des essais de comestibilite effectues au Royaume-Uni. (author) [Spanish] En la memoria se describen las pruebas de comestibilidad realizadas en el Reino. Unido como parte del programa de irradiacion de alimentos. Se han efectuado estudios a corto plazo con ratas, pollos y cerdos, y a largo plazo con ratas y ratones, y no se han observado efectos perniciosos que puedan atribuirse al consumo de alimentos irradiados por dichos animales. Estas pruebas se efectuaron pensando en procesos especificos de irradiacion con dosis bajas o moderadas. Se utilizaron, en efecto, cereales sometidos a 20 000 y 200 000 rad de rayos gamma y huevos congelados, irradiados con 0,5 y 1,0 Mrad para eliminar las Salmonellae. Ademas se han realizado pruebas con jamon tratado con dosis de 250 000 rad, para prolongar su periodo de almacenamiento, y con dosis de 2 Mrad. Se estan ejecutando estudios a largo plazo con el fin de investigar la comestibilidad del pescado tratado con 0,6 Mrad (la dosis maxima que probablemente se administrara para prolongar el periodo de almacenamiento en frigorifico (0 Degree-Sign -4 Degree-Sign C)). Tambien se han emprendido pruebas de corta duracion con patatas (10 000 rad) y carne de caballo (0,65 Mrad). Se han investigado, por analisis microbiologico, las.propiedades nutritivas de los cereales, los huevos, el pescado y algunos alimentos de consumo animal irradiados. Las perdidas de vitaminas B son analogas a las indicadas por investigadores de los Estados Unidos, y son del mismo orden de magnitud que las que ocasiona el tratamiento termico, aunque se ha observado que la sensibilidad d Inverted-Question-Mark determinadas vitaminas al calor y a la irradiacion es diferente. Las perdidas de vitaminas B producidas por irradiacion y cochura son acumulativas. No se ha observado efecto alguno en el valor nutritivo de las proteinas. En 1962, el Ministerio de Sanidad Publica del Reino Unido constituyo un Grupo de trabajo encargado de estudiar los efectos de las radiaciones en los alimentos y de presentar un informe sobre la necesidad de controles oficiales. En la memoria se examina el informe del Grupo de trabajo, publicado en 1964, en relacion con las pruebas de comestibilidad efectuadas en el Reino Unido.

This report for the Swiss Federal Office of Energy (SFOE) takes a look at a project for the realisation of a small hydro-power plant on the drinking water supply in the municipality of Vira Gambarogno, southern Switzerland. The old conduit connecting two drinking water reservoirs has to be replaced. The elevation difference of 260 m is favorable to the installation of a turbine near the lower reservoir. The report presents details on the hydrological data and the dimensioning of the installation. Several variants are considered, which also include the possible reconstruction of the lower reservoir and/or an increased water flow rate from the springs. The electricity production expected is discussed, as is the economic viability of the project.

Estas seran menos costosas que los radioisotopos puros, pues se suprimen los gastos de separacion y purificacion de isotopos. En la actualidad funcionan o estan a punto de funcionar generadores termoelectricos prototipo, alimentados con estroncio-90 y cesio-137, en estaciones meteorologicas, dispositivos auxiliares de navegacion y aparatos de vigilancia de las profundidades del mar. En el espacio funcionan generadores termoelectricos de plutonio-238 como fuentes de energia electrica del satelite TRANSIT de la Marina de los Estados Unidos. Se estan construyendo asimismo generadores para los proyectos espaciales de la National Aeronautics and Space Administration de dicho pais. La elevada radiactividad inherente a las fuentes radioisotopicas de energia exige que se preste especial atencion a la seguridad de las mismas. Se han establecido rigurosas normas de proteccion y se han ejecutado ensayos muy avanzados para poder emplear estos dispositivos sin originar riesgos inaceptables.

ingeslagen. Keswick en zending zijn sinds die tijd ongescheiden en de KC is een factor van betekenis geworden in het leven van de universele kerk. De jaren door heeft het onderdeel zending een grote plek in het programma. Dit bracht de voorzitter van de KC, Aldis, vlak na WO II er toe om te zeggen: ‘Ik denk dat de KC meer gedaan heeft dan enig andere beweging in de kerken om mannen en vrouwen te roepen naar het zendingsveld.’ Op de website van de Conventie staat nu: De KC is gepassioneerd over zending en heeft support, bemoediging en onderdak verleend aan zendelingen en hun families voor meer dan honderd jaar. We zien dit als de sleutelrol van Keswick en een grote factor voor velen om concreet met de zending mee te leven. Op welke wijze is de zendingsvisie van het begin leidend in de KC nu in de een en twintigste eeuw?

Full Text Available Mutilations of female genital organs are a particularly difficult issue. That is the reason why it occupies historical, anthropological and medico-legal research. So the present article considers the situation in all these aspects together with the provisions introduced by Law n. 7, 9/1/2006 and article 583 bis of the Criminal Code for the Protection of the rights of women being mutilated.Indeed we believe that the mutilations are real and cause personal psychic injury. The custom of mutilation has nothing to do with religious beliefs, but is the product of old social prejudices against women, as an individual.La MGF (mutilation génitale féminine est un sujet de société tristement actuel dont on dit qu'elle est pratiquée au nom des croyances religieuses les plus ancestrales.C’est la raison pour laquelle j’ai voulu avant tout consulter, bien que brièvement, l'analyse anthropologique, historique, médico-légale et juridique effectuée sur cet argument pour me pencher ensuite sur la loi italienne n° 7 du 9/1/2006 et sur l’article n° 583bis du Code Pénal Italien, ayant trait à la sauvegarde des droits inaliénables de la femme qui subit une mutilation.En effet les mutilations sont de véritables lésions physiques et souffrances psychiques qui plus que motivées par des croyances religieuses sont dictées par d'anciens us et coutumes combles de préjugés sociaux envers la femme en tant qu’individu.Le mutilazioni degli organi genitali femminili rappresentano un tema tristemente attuale legato per “comodità” alle credenze religiose più arcaiche.Per questo motivo, l’articolo ha voluto, da subito, volgere uno sguardo, seppur breve, all’analisi antropologica, storica e medico-giuridica dell’argomento per poi considerare la legge n. 7 del 9/1/2006 (che ha attuato i principi della Dichiarazione e del Programma della IV Conferenza mondiale dell’ONU sulle donne - Pechino 1995, nonché le disposizioni degli artt. 2,3,32 della

.Argomento centrale di questo articolo è il gioco d’azzardo ed in particolare la patologia che esso può indurre. Al fine di introdurre il tema, viene esaminata l’organizzazione del gioco pubblico in Italia ed il contesto normativo in cui la materia è inserita. E’ poi analizzato l’inquadramento clinico della patologia e le caratteristiche di personalità e comportamentali tipiche del giocatore d’azzardo problematico. Dopo una breve disamina dei diversi programmi di trattamento della patologia, viene approfondita la particolare forma di terapia del gruppo di auto-aiuto dei “Giocatori Anonimi”. Essa rappresenta il contesto clinico all’interno del quale si è svolta una ricerca, che ha coinvolto 10 membri di un gruppo dell’associazione Giocatori Anonimi di Firenze, volta ad approfondire due aspetti peculiari dei giocatori d’azzardo patologici, cioè quelli relativi alle loro modalità erronee di pensiero concernenti il gioco ed alla loro decisione di partecipare al programma. In conclusione, data la gravità di questa patologia ai più sconosciuta, sono analizzate alcune importanti misure di prevenzione e di tutela dei giocatori d’azzardo problematici.

Archeologia e città: la ricostruzione della linea di costa

Full Text Available Argomento del contributo è la storia del paesaggio costiero antistante il nucleo più antico della città di Napoli ricostruita attraverso la procedura dello scavo archeologico, nel corso dei lavori per la realizzazione della linea 1 e 6 della Metropolitana. L’intervento archeologico si è rivelato un’occasione irripetibile di conoscenza, per la sua ampia dimensione e per la circostanza che si è sviluppato in un comparto topografico unitario quale il water front cittadino. Esso appare straordinario per l’intreccio di fattori diversificati: per la sua complessità tecnica e metodologica, per la rilevanza delle acquisizioni scientifiche, per lo stretto rapporto con un’opera pubblica di carattere ingegneristico che è parte di una delle più importanti trasformazioni della città contemporanea, avviata attraverso il Piano comunale dei trasporti. Occorre innanzitutto sottolineare che le indagini, dal punto di vista metodologico-procedurale, documentano una precoce attività di archeologia preventiva, avviata sin dalla metà degli anni ‘90 del secolo scorso, in un momento lontano dalle leggi vigenti che regolamentano l’impatto archeologico rispetto alle opere pubbliche. Nello stesso momento dell’inserimento di norme specifiche di tutela archeologica nella variante del PRG della città di Napoli, in base ad una concertazione fra il Ministero per i Beni e le Attività Culturali, il Comune di Napoli e la Società Metropolitana, Concessionaria delle opere, si sono inserite le attività di natura archeologica , dalle prospezioni preliminari sino alle indagini estensive delle stazioni, all’interno del programma dell’opera pubblica di cui sono diventate una fase operativa preliminare e ineludibile. Il progetto della linea 1, il cui obiettivo è di collegare alla fascia collinare della città, di recente servita da un efficiente trasporto su ferro, il nucleo più antico dell’insediamento napoletano, risparmia l’area urbana di Neapolis

-southern part of the potentially suitable area mentioned above, finally further subdivided in 2 priority levels. [Italiano] Il lavoro presenta i risultati ottenuti dall`ENEA nell`ambito di un incarico conferito dall`Amministrazione Provinciale di Lucca, riguardante la localizzazione delle aree idonee all`installazione di un impianto di termoutilizzazione energetica di CdR (Combustibile derivato dai Rifiuti) e di una discarica ad esso associata, in sintonia con gli indirizzi contenuti nel `Programma politico d`azione della Comunita` Europea a favore dell`ambiente e di uno sviluppo sostenibile`. La ricerca e` stata effettuata dall`ENEA attraverso il supporto di metodologie, basate su criteri di natura ambientale, gia` precedentemente applicate a diverse situazioni territoriali italiane (Provincia di Cremona, Comune di Latina ecc.). Nel territorio in oggetto la localizzazione e` stata ricondotta alle problematiche connesse con quella delle discariche, che presentano generalmente maggiore impatto ambientale. Per calcolare l`impatto dei rilasci del termoutilizzatore nella fascia di potenziale idoneita` e` stato effettuato uno studio meteo-diffusivo per calcolare i livelli medi annui di concentrazione in aria a livello del suolo dei principali inquinanti (CO, SO2, NO2, ecc.) e le deposizioni (secca e umida), assumendo come emissioni al camino i valori limite imposti dalle direttive CEE; i valori medi calcolati sono risultati notevolmente al di sotto dei limiti di legge (DPR 203/1988). Sono stati infine selezionati 14 siti, concentrati prevalentemente nella porzione centro-meridionale della fascia suddetta, successivamente suddivisai in due classi di priorita` sulla base di motivazioni ambientali (elevata soggiacenza della falda, assenza di rischio di alterazione dei processi ecologici, scarso impatto sulle attivita` agricole), logistiche (maggiore estensione media con possibilita` di ospitare tutti gli impianti) e socioeconomici (presenza di grandi complessi industriali, minore

blijkt het optimaal koppelen van een datacommunicatie infrastructuur in de woning voor het uitwisselen van boodschappen tussen energie gebruikende systemen, naast een 'first-mile'-connectie met de buitenwereld voor het aanleveren van stuurinformatie, via bijvoorbeeld Internet, een essentiele randvoorwaarde. Uitgaande van de vereistenspecificatie wordt een mogelijke hardware en software architectuur besproken. Een intelligente 'gateway', de E-box, een intermediair, die de externe koppeling van het apparatennetwerk verzorgt, en tevens de sturing van apparaten via het netwerk in de woning op zich neemt, vervult in deze architectuur een sleutelrol. Aan de E-box kan ook een rol worden toegekend voor het meten en actief feedback geven over verbruiken, als aanvulling op of als vervanger voor de stroom- en/of gasmeter in een intelligente meterkast. De E-Box architectuur is in een werkend simulatie programma geimplementeerd. Tevens zijn de tijdsafhankelijke energiekarakteristieken (vraag, aanbod, co-generatie) van systemen in woningen gekarakteriseerd. Aan de hand daarvan is een aantal veelbelovende mogelijkheden van bedrijf van de E-box in kaart gebracht voor bedrijfsscenario's in de zomer- en de wintersituatie. In deze scenario's wordt voor verschuifbare vraag (elektriciteit, warmte) het aanbod van locale duurzame bronnen maximaal gebruikt. Er zijn tevens scenario varianten berekend, waarin de effecten van meer real-time energieprijzen dan de nu gebruikelijke vaste of hoog/laag tarieven, zijn meegenomen. Afhankelijk van de mate waarin de energieprijzen meer op deze marktontwikkelingen zijn afgebeeld, blijkt de kostenbesparing tot ongeveer 15% te kunnen oplopen. Worden ook mogelijkheden voor buffering van elektriciteit of tariefscenario's meegenomen op dagen, waarop de APX grote schommelingen vertoonde, dan is een kostenbesparing met nog eens een dergelijk percentage haalbaar. Tot slot komt het businessmodel en eventuele vermarkting van een E

horizontal de varios parametros oceanograficos, el autor de la memoria indica la circulacion, hasta 150 metros de profundidad, en diferentes niveles a lo largo del litoral indio. Las secciones verticales permiten determinar la circulacion en diferentes niveles hasta 500 metros de profundidad. El nivel de las aguas estaticas parece estar situado muy por debajo de los 500 metros y varia segun el lugar y e] tiempo. La mezcla de las aguas se deduce de las relaciones tiempo-espacio. Tambien se senala en la memoria en que estaciones del ano y en que regiones se observan corrientes ascendentes y descendentes frente a la costa. La intensidad de las corrientes ascendentes es mas pronunciada en el litoral, por lo que durante la estacion correspondiente se produce una renovacion total de las masas de agua de la plataforma continental. A mayor profundidad, las masas de agua mas caudalosas son, por orden de importancia, las aguas ecuatoriales del Indico, las aguas intermedias del Antartico junto con las del mar Rojo y una ligera mezcla de las del Indico Centra], las aguas profundas del Indico y las aguas del fondo del Antartico. El autor indica la distribucion de esas masas de agua y la circulacion de las aguas profundas al norte del ecuador. Desde hace 60 anos, las aguas del fondo del Antartico parecen estar avanzando hacia el norte del ecuador tanto en el golfo de Bengala como en el mar Arabigo. Esto ha producido, en el golfo y en el mar Arabigo, un descenso del indice de salinidad. Por ultimo, el autor sugiere un programa de trabajos oceanograficos relacionados con la evacuacion sin riesgos de desechos radiactivos, particularmente en el mar Arabigo.

Document available in extended abstract form only. The current management strategy in the Netherlands for radioactive waste is interim storage for approximately 100 years, followed by final deep geological disposal. At present, both Boom Clay and Salt formations are being considered and investigated via the OPERA (Onderzoeks Programma Eindberging Radioactief Afval) and CORA (Commissie Opberging Radioactief Afval) research programmes respectively, instigated by COVRA (Centrale Organisatie Voor Radioactief Afval). This paper outlines the on-going investigation into the initial technical feasibility of a high-level radioactive waste disposal facility, located within a stratum of Boom Clay, as part of the OPERA research programme. The feasibility study is based on the current Belgian Super-container concept, incorporating specific features relevant to the Netherlands, including the waste inventory and possible future glaciation. The repository is designed to be situated at approximately 500 m depth in a Boom Clay stratum of approximately 100 m thickness, and will co-host vitrified High Level Waste (HLW), spent fuel from research reactors, non-heat generating HLW, Low and Intermediate Level Waste (LILW) and depleted uranium. The total footprint is designed to be 3050 m by 1300 m, and will be segregated by waste type. The waste will be stored in drifts drilled perpendicular to the main galleries and will vary in length and diameter depending upon waste type. The repository life-cycle can be considered in three phases: (i) the pre-operation phase, including the conceptual development, site investigation and selection, design and construction; (ii) the operational phase, including waste emplacement and any period of time prior to closure; and (iii) the post-operational phase. The research on the technical feasibility of the repository will investigate whether the repository can be constructed and whether it is able to perform the appropriate safety functions and meet

(MCBR). Al calcular la reactividad, se comprueba que el coeficiente correspondiente a la densidad neta del mercurio en el primer proyecto del MCBR es negativo en algunas regiones, y positivo en otras. Es negativo en las regiones de peso estadistico maximo y en las que los cambios de densidad serian mayores al variar la potencia. Por lo tanto, el coeficiente global de densidad del mercurio es negativo, esto es, el coeficiente de vacios es positivo, lo que constituye una condicion que implica peligro. En la formulacion de dos grupos, se aprecia facilmente que modificaciones es preciso introducir en el diseno para que el coeficiente de cavidad sea negativo. Nuevas investigaciones demostraron que era posible introducir dichas modificaciones, lograndose establecer para el MCBR un diseno cuyo coeficiente de vacios es negativo.

-current operation mode. This was depending on the excessive length of the drum designed also for counter-current mode, so that ashes melted in the first part solidify in the second part because of heat losses. In conclusion, plant operation resulted satisfactory, also under the environmental aspects, despite of the very severe test conditions, with high chlorine content and the presence of aromatic compounds and copper, which acts as catalyst in the novo-synthesis of dioxins. Incineration and co-incineration of sewage sludge and hazardous compounds were therefore demonstrated to be a safe and viable disposal option. [Italian] L' incenerimento dei fanghi di depurazione e' una valida altenativa ai sistemi utilizzati per lo smaltimento (utilizzazione agricola, discarica controllata) nei casi in cui si trovino difficolta' di applicazione per la presenza di inquinanti in concentrazione superiore ai limiti consentiti o per situazioni contingenti spesso non prevedibili. Tuttavia, esso puo' essere causa di emissione in atmosfera di microinquinanti inorganici (metalli pesanti) e organici (IPA, PCDD, PCDF), oltre che di materiale particolato e di ossidi di azoto e di carbonio (NO{sub x} e CO), e composti acidi; cio' ha ingenerato una forte avversione popolare che ha ostacolato la utilizzazione. L'Istituto di Ricerca sulle Acque del CNR ha pertanto realizzato, nell'area dell'impianto di depurazione di Bari Ovest, un impianto dimostrativo di incenerimento costituito essenzialmente da due forni, uno a letto fluido e uno a tamburo rotante, da un essiccatore, da un sistema di recupero termico e da una sezione di abbattimento delle polveri e degli altri macroinquinanti, e ha messo a punto un programma di ricerca per verificare la compatibilita' ambientale e il rispetto della normativa vigente nell'incenerimento dei fanghi con particolare riferimento alle emissioni di microinquinanti organici ed al destino dei metalli.

enterprises, the topic of infrastructures plays a dominant role. The need to re-balance and re-establish a relationship with the town definitely requires a new planning of existing tracks, accesses, and relational spaces.Come altre realtà urbane di costa, anche Senigallia, nell’ultimo decennio, si colloca tra quelle città d’acqua, di medie dimensioni, attente a ridisegnare e riorganizzare gli spazi di interfaccia tra contesti urbani e gli ambiti delle attività fronte mare. Un tentativo di ricomporre una continuità tra le trame della città, le aree funzionali della costa e delle sponde e il sistema delle sue infrastrutture. Lo scenario morfologico che appare oggi, per Senigallia, racconta una città i cui confini si affermano sul fronte mare, variamente segnati dalla richiesta di protezione e difesa sulla linea della costa o viceversa incalzati, in tempi più recenti, dalle ragioni dello scambio e dei commerci. Una città divisa dalla cesura del fiume Misa, primaria infrastruttura lineare, che impone le leggi insondabili delle piene e dei reflussi mentre reclama gli strumenti per il controllo delle acque, una città spezzata dalla lacerazione imposta dalla linea ferrata, sistema dirompente ed escludente (per Senigallia e per lunga parte della costa adriatica. In questi termini il progetto, come campo di sperimentazione, si prefigura, insieme ad adeguate gestioni e controllo delle politiche urbane, come valido strumento tecnico-operativo per esplorare risposte progettuali in grado di ricucire l’apparente insanabile frattura che l’estraneità funzionale delle rive del fiumi o il degrado di coste malamente urbanizzate o infrastrutture non perfettamente integrate nella dinamica urbana hanno determinato. La registrazione da più parti di esperimenti progettuali che vanno in questa direzione ci avverte di un significativo cambiamento dei paradigmi progettuali applicabili alla realtà senigalliese inseriti in un vasto programma di riqualificazione da parte dell�

pescado con {sup 60}Co, de 250 000 Ci. Los ensayos de envase y transporte de productos irradiados en condiciones comerciales simuladas muestran que el pescado pasteurizado puede manipularse de la misma manera que el pescado fresco, pero el periodo de almacenamiento del primero es dos veces mayor que el del segundo. En cooperacion con entidades particulares y oficiales, se han expedido a diversos puntos de los Estados Unidos, en vehiculos comerciales, pescados y mariscos irradiados y se ha estudiado su calidad. Los resultados son muy alentadores e indican que este proceso seria sumamente util para la industria. La irradiacion de pescado en el mar permitira desembarcar mayores cantidades de pescado fresco. Los resultados iniciales indican que quiza sea posible irradiar en el mar el pescado (una vez extraidas las visceras) en dosis inferiores a 100 krad, y volverlo a irradiar en tierra una vez cortado en filetes y envasado.

propagacion de los neutrones en la materia abarca desde algunas decenas de kiloelectron-voltios , para los nucleos pesados, hasta unos cuantos mega-electron-voltios, para los nucleos intermedios. Para poder tener en cuenta los efectos de resonancia en el calculo de los parametros de los grupos, es indispensable conocer no solo las secciones eficaces medias correspondientes a las reacciones de los neutrones con la materia, sino tambien algunas magnitudes tales como (1/{Sigma}{sub t}), (1/{Sigma}{sub t}{sup 2}) etc. - los corchetes indican que se toman valores promedios de los grupos energeticos. La informacion de que se dispone actualement acerca de los parametros de resonancia en el terreno de los neutrones rapidos no permite calcular las magnitudes mencionadas con la exactitud necesaria. Por tal razon interesa medir directamente (1/{Sigma}{sub t}), (1/{Sigma}{sub t}{sup 2}) y otros valores analogos. Los autores presentan los resultados de las mediciones de una serie de parametros tales como ({Sigma}{sub t}), ({Sigma}{sub t}{sup 2}), (1/{Sigma}{sub t}), (1/{Sigma}{sub t}{sup 2}), (1/{Sigma}{sub t}{sup 3}), etc. que caracterizan la estructura de las secciones eficaces de una serie de nucleos intermedios para neutrones de energia comprendida entre 300 keV y 3 MeV. Dichos valores se dedujeron analizando las curvas de paso a traves de la materia, obtenidas con una geometria favorable, hasta un valor limite de 10{sup -2}, aproximadamente . Los datos obtenidos demuestran que los efectos de resonancia ejercen una notable influencia sobre las caracteristicas de la difusion en la materia.

Consideraciones de orden tecnico indican que, en los grandes centros de exportacion o almacenamiento de granos, la irradiacion puede competir economicamente con los metodos quimicos. Una vez establecido que el almacenamiento en grandes cantidades y los sistemas automaticos de transporte son los procedimientos mas rapidos y economicos para hacer llegar el grano a los consumidores, se puede predecir con bastante seguridad que en un futuro no muy lejano la irradiacion constituira una de las etapas del proceso de distribucion del grano.

Mobilità è l’ultimo nato tra questi ed è uno strumento prevalentemente strategico in quanto agisce sul sistema nel suo complesso ipotizzando una generale razionalizzazione ed evoluzione di reti e mezzi. L’articolo approfondisce i caratteri di questo strumento, a partire dalle previsioni legislative ed in relazione a specifici casi applicativi. In particolare, la prima parte analizza i concetti che sono alla base delle relazioni tra città, mobilità urbana e regolazione della sosta. Nella seconda parte si analizzano gli aspetti normativi, ossia il Piano Urbano della Mobilità, anche in relazione ad uno strumento che lo ha preceduto e che era specificamente indirizzato alla programmazione delle infrastrutture per la sosta, il Programma Urbano dei Parcheggi. La terza parte analizza due casi di applicazione dello strumento, relativi alle città di Ferrara e Perugia con lo scopo di evidenziare le diverse opzioni che si aprono davanti al pianificatore nel momento in cui è necessario applicare lo strumento teorico ad una specifica realtà urbana. Infine, nella quarta parte, sono messe in evidenza alcune delle tecniche e degli strumenti utilizzabili per la risoluzione del problema della sosta in relazione ai tipi di sosta, alle diverse modalità per la sua organizzazione e alle tecniche di gestione indirizzate a favorire comportamenti più corretti in relazione ai diversi ambiti urbani.

calientes; la retencion se expresa en funcion de dos tipos de parametros, a saber: 1) la probabilidad relativa de que ei choque de un atomo caliente de halogeno radiactivo con una molecula determinada produzca la retencion del atomo caliente en dicha molecula; 2) los limites energeticos superior e inferior dentro de los cuales el atomo de bromo puede considerarse caliente. Los autores demuestran como el primer tipo de parametro puede deducirse experimentalmente de mezclas binarias de un haluro organico y el correspondiente halogeno libre; el segundo tipo de parametro debe deducirse a partir de datos nucleares quimicos. Dichos metodos han sido ensayados en los sistemas C{sub 2}H{sub 5}Br/CCl{sub 4}/Br{sub 2} and C{sub 2}H{sub 5}Br/C{sub 6}H{sub 5}Br/Br{sub 2}. Los valores calculados para las retenciones (empleando parametros derivados del estudio de los sistemas C{sub 2}H{sub 5}Br/Br{sub 2}, CCl{sub 4}/Br{sub 2} and C{sub 6}H{sub 5}Br/Br{sub 2})) eoncuerdan satisfactoriamente con los dalos hallados experimentalmeme en mezclas cuya fraccion molar de bromo es superior a 0,1. De esta manera se considera que el mecanismo propuesto por Libby permite explicar las retenciones organicas observadas en dichas mezclas. Cuando la fraccion molar de bromo se va reduciendo a valores inferiores a 0,1, las retenciones observadas se hacen progresivamente mayores que los valores calculados. Este fenomeno se atribuye a la existencia de otros modos de marcacion con atomos calientes, que entran en juego cuando la concentracion de bromo no es bastante elevada para eliminar adecuadamente los radicales en virtud de mecanismos de depuracion.

debido a su abundancia, a sus propiedades nucleares y a la relativa facilidad con que permite construir generadores compactos de calor. Se emplean ya generadores a base de estroncio-90 para suministrar energia a centrales meteorologicas automaticas y aparatos auxiliares para la navegacion, y se esta estudiando la posibilidad de emplear este isotopo como fuente de energia para vehiculos espaciales. Se estudiaron diversos compuestos de estroncio que podian servir para este fin y se eligio el titanato porque reune las propiedades mas adecuadas. El estronico-90 se separa del resto d e los productos brutos de fision y se purifica hasta el grado requerido en las instalaciones de Hanford de la Comision de Energia Atomica de los Estados Unidos. Seguidamente se introduce en forma de carbonato en la ''celda caliente'' de la Martin Company, donde se transforma en pastilla, de titanato. Se sigue e l mismo proceso que en las tecnicas quimicas y ceramicas, pero adaptado para la manipulacion a distancia. Seguidamente las pastillas se encapsulan en recipientes de ''Hastelloy C'' para emplearlas en los generadores de energia termoelectrica. Estos procesos presentan problemas poco corrientes debido a que las grandes cantidades de estroncio-90 que se manejan (que podrian alcanzar millones de curies por ano) pueden originar gravisimos riegos radiologicos y de contaminacion. La memoria describe la instalacion, el equipo, el proceso y los criterios de seguridad. Describe tambien la experiencia adquirida recientemente al elaborar el combustilble para el generador SNAP-7 con los primeros 250 000 s de estroncio-90.

tanques subterraneos. Como esta operacion solo se considera provisional, se esta llevando activa mente a la practica un programa encaminado a reducir la movilidad de los materiales almacenados a fin de mejorar el confinamiento a largo plazo. En los actuales tanques subterraneos, se evaporaran hasta obtener tortas de sal grandes volumenes de desechos de desenvainado que en esencia no son autocalentadores. Los estudios de laboratorio y los primeros ensayos efectuados en un tanque de 5 000 gal demuestran que el paso de una corriente de aire caliente a traves de la solucion, junto con una carbonatacion controlada para transformar elhidroxidodesodio libre en carbonato de sodio, permite eliminar bastante agua para formar una torta de sal no higroscopica. Los desechos auto- calentadores se fraccionaran para poder almacenar por separado los emisores de periodo largo en pequenos recipientes de gran solidez. Estos materiales podrian aprovecharse en casos especiales. Despues de que los emisores autocalentadores de periodo corto se hayan ''friado''urante 5 a 10 a, los desechos salinos residuales se combinaran con los desechos corrientes de desvainado y se evaporaran para formar tortas de sal. Para llevar a cabo el tratamiento quimico necesario, se estan introduciendo ciertas modificaciones en un antiguo edificio con pasillos blindados. Probablemente se recurrira a la extraccion por solvente (D2EHPA) para separar el estroncio y el cerio de los desechos acidos; aun no se ha decidido si la aislacion del cesio se efectuara mediante extraccion por solventes, el intercambio ionico o la precipitacion. Se confia que la operacion completa podra llevarse a cabo alrededor de 1966.

Parking Policies in Tourist Cities Politiche della sosta in città turistiche

miglioramento delle condizioni di spostamento e per garantire buoni livelli di sicurezza stradale. La realizzazione di strutture per la sosta in ambito urbano, invece, è regolamentata dal programma urbano dei parcheggi introdotto alla fine degli anni ottanta. All’interno di tali strumenti, le indicazioni relative alla predisposizione di specifiche aree da destinare alla sosta turistica occupa un ruolo marginale. La totalità delle indicazioni relative alla mobilità turistica fanno riferimento a due tipi di interventi: –istituzione di una zona a traffico limitato per la circolazione dei bus turistici; –individuazione delle aree di sosta breve dove è consentito ai visitatori di scendere o salire dal bus. In relazione alla sosta, le indicazioni si riferiscono alla individuazione di aree urbane o di assi stradali dove viene consentito lo stazionamento temporaneo. Molto raramente, per quel che riguarda la situazione italiana nelle principali città turistiche, gli interventi prevedono la realizzazione di specifiche strutture integrate al trasporto pubblico o a modalità di spostamento sostenibile che garantirebbero una migliore distribuzione dei flussi turistici consentendo al contempo al visitatore differenti modalità di visita con positivi effetti anche sulla percezione della visita. Nel tentativo di dimostrare come gli interventi finalizzati alla realizzazione di aree per la sosta dei bus turistici possano essere strumenti di riqualificazione fisica e funzionale della città, l’articolo nella prima parte si focalizza sulla definizione delle caratteristiche della domanda di spostamento turistico in ambito urbano. Nella seconda parte, attraverso una panoramica delle politiche della sosta urbana in Italia si evidenzia la carenza di interventi finalizzati alla realizzazione di una rete per la sosta turistica integrata all’offerta di servizi urbani. Nella parte conclusiva si individuano gli elementi che consentirebbero alle aree di sta di porsi come aree di qualit

ia calidad del combustible utilizado se considera indispensable controlar el conjunto del elemento y la totalidad de la produccion. Este control no puede realizarse por micrograffa debido al tiempo prolongado que esta requiere y a sus resultados de caracter parcial. El metodo de control adoptado se basa en el principio de la absorcion de ondas ultrasonicas por los distintos materiales. Dicha absorcion es funcion de la estructura del medio. Si {lambda} es pequena en comparacion col el tamano del grano G, la absorcion resultara debil mientras que si G es del orden de {lambda}/2, la absorcion sera muy considerable. Los primeros ensayos se efectuaron en aire, utilizando ecos multiples y midiendo la altura del primer eco; los siguientes se realizaron por transmision en agua, comparando la altura del eco transmitido con la del inicial. En el control industrial, se compara la amplitud del eco transmitido por el material con la del obtenido usando una probeta patron sometida al tratamiento correcto, de la misma composicion y de igual forma geometrica. La inspeccion se realiza en una maquina especial; los materiales se hacen girar mediante roldanas y los transductores orientables se desplazan a lo largo del elemento. La exploracion helicoidal se lleva a cabo con un paso inferior a 5 mm. El generador de ondas ultrasonicas comprende un sistema de regulacion que mantiene constante la intensidad del eco de referencia. Se presenta una serie de registros obtenidos con diversas aleaciones y, en particular, defectos observados en elementos tratados por induccion durante el avance lineal. Se detectan zonas de tratamiento deficiente, de area inferior a 1 cm{sup 2}. En la actualidad se controlan de esta manera todos los combustibles aleados de bajo contenido de uranio destinados a los reactors G2, EL3, EDF1, EDF2 e INCA, es decir, barras y tubos con diametros comprendidos entre 20 y 95 mm.

Teoreticheskoe issledovanie zdes' zachastuju privodit k nekotorym trudnostjam, svjazannym s konvergenciej. Pojetomu neobhodimo sravnenie s raspredelenijami izmerennyh potokov. 2.

Prostranstvennaja moshhnost' pervichnogo istochnika proporcional'na poperechnomu secheniju delenija topliva, kogda reshetka takzhe raschityvaetsja kak funkcija prostranstvennyh koordinat.

De este modo, la dispersion de interes puede distinguirse de los efectos no magneticos como diferencia entre dos intensidades medidas. Un proceso que contribuye al fondo de dispersion difusa, en parte de caracter magnetico y que, por tanto, la mencionada tecnica no elimina, es la dispersion miiltiple de Bragg en un poli- cristal magnetico. Puede prevenirse utilizando una muestra monocristalina o empleando neutrones de gran longitud de onda, de forma que impidan los procesos de Bragg. En Harwell se ha construido un instrumento basado en este principio, que se utiliza para una amplia serie de mediciones en aleaciones ferromagneticas diluidas. Se examinan estos experimentos y otras novedades que cabe anticipar en la materia, entre ellas la medicion de la dispersion magnetica difusa en sales paramagneticas. El estudio de esta dispersion reviste enorme interes, pues proporciona informacion dilecta sobre la cantidad de spin transmitida por un ion magnetico a los ligandos que le rodean como resultado de la covalencia.

Por mas que la clorotiazida incremento la excrecion de potasio hasta 1,5 veces con respecto a los valores de referencia, no se comprobo que tuviera ningun efecto apreciable sobre la excrecion de cesio ni que redujera la carga corporal del mismo. Todos los sujetos excretaron rapidamente una pequena fraccion de cesio (10 a 20%) con un perfodo biologico (T{sub b}) inferior aid. El resto fue excretado en proporcion'constante con un de 90 a 155 d. Mas del 70% del cesio se excreto diariamente por via renal. El T{sub b} del potasio se calculo tambien por la formula: T{sub bK} = Total body K/Urine K x 0,693 x 0,8 admitiendo que el 80%-del potasio total excretado lo sea por via renal. El T{sub b} del K fue de 35 a 42 d. La razon de discriminacion T{sub bCs}/T{sub bK} escilo entre 2,1 y 3,8. Estos resultados demuestran que el cesio y el potasio no se utilizan de manera intercambiable. El cesio es retenido con preferencia al potasio y las alteraciones de la renovacion del potasio no ejercen ninguna influencia sobre la del cesio.

Bylo obnaruzheno, chto skorost' obmena rezko vozrastaet s vozrastaniem koncentracii HCl (pri 25 Degree-Sign S ot 0,8 do 2,0 M) i pri 2,0 M koncentracii HCl skorost' dostigaet maksimuma, posle kotorogo skorost' padaet s uvelicheniem koncentracii HCl (pri 25 Degree-Sign S ot 2,0 do 4,0 M). Pri issledovanijah byli ispol'zovany dve raznovidnosti Sbv, to est' odna byla ispol'zovana neposredstvenno posle razvedenija rastvora 10 M HCl Sbv vodoj i drugaja - posle 24 chasov otstaivanija pri komnatnoj temperature iz rastvora. V oboih sluchajah maksimal'nye sko- rosti byli obnaruzheny pri koncentracii 2,0 M HCl. Skorost' R{sub 1} dlja pervoj (neposred- stvenno posle razbavlenija) sostavila 4,5 * 10{sup -6} mol' litr{sup -1} min{sup -1}, i skorost' R{sub 2} dlja vtoroj (otstaivalas' v techenie 24 chasov) byla 1,2 * 10{sup -6} mol' litr{sup -1} min{sup -1} . Energija aktivacii dlja ukazannyh sluchaev ravnjalas' 12,2 kkal/mol' i 19,1 kkal/mol'. Pri pomoshhi spektrofoto- metricheskih issledovanij bylo obnaruzheno, chto raznovidnosti Sb{sup V} pervogo tipa sostojat glavnym obrazom,iz SbClg, a raznovidnosti vtorogo tipa - iz SbCl(OH){sup -}{sub 2} i t . d . Pomimo jetih faktov bylo obnaruzheno, chto forma raznovidnostej Sb{sup III} ne okazyvaet nikakogo vlijanija na skorost' obmena. Bolee rezkoe vozrastanie skorosti obmena otmechalos', kogda koncentracija HCl v ras- tvore sur'my byla 0,8 M, a koncentracija hlorida byla uvelichena do 3,0 M s dobavleniem LiCl. Primechatel'no, chto pochti linejnoe i rezkoe uvelichenie skorosti otmechalos' do kon- centracii hlorida 2,0 M. Jeti fakty, poluchennye pri postojannoj koncentracii vodorodnyh ionov, navodjat na mysl', chto atomy hlorida igrajut rol' mostikovyh atomov v obrazovanii

annotacii my podvodim itog nedavnej raboty po izucheniju vzaimodejstvija jelektronnogo puchka s plazmoj, prodelannoj v Massachuzetskom tehnologicheskom institute. Kogda jelektronnyj puchok prohodit cherez plazmu, on vozbuzhdaet kolebanija na plazmennoj chastote. Jeti mikrovolnovye kolebanija podderzhivajut mikrovolnovyj razrjad, i my nazvali ves' process ''puchkovym razrjadom'. Ionizacija okruzhajushhego gaza osushhestvljaetsja jelektronami vysokoj jEhnergii iz plazmy, kotorye uskorjajutsja poljami kolebanij. Rezul'tatom javljaetsja obrazovanie gorjachej jelektronnoj plazmy vnutri ustanovki s magnitnymi probkami. Poskol'ku parametry razrjada puchka v plazme predstavljajutsja neblagoprijatnymi dlja neposredstvennogo ionnogo nagreva vzaimodejstviem puchka s plazmoj, my pristupili k jeksperimentam, v kotoryh dopolnitel'naja radiochastotnaja jenergija nakladyvaetsja s cel'ju vozbuzhdenija ciklotronnyh kolebanij ionov dlja ionnogo nagreva. Rassmotreniju podlezhat ustojchivost' plazmy; plotnost', srednjaja jenergija i maksimal'naja jenergija jelektronov plazmy; i predvaritel'nye rezul'taty po ionnomu nagrevu. Provodjatsja jeksperimenty s pul'sirujushhim jelektronnym puchkom v 10-15 kv i 10 - 15 A, kotoryj inzhektiruetsja vdol' osi magnitnyh probok v'oblast' drejfa, soderzhashhuju H{sub 2} np 10{sup -5}-10{sup -4} torr. Plotnost' jelektronov plazmy ob{sup e}mom v 1 litr obychno sostavljaet 10{sup 12}-10{sup 13} sm{sup -3} i plotnost' poperechnoj jEhnergii obychno sostavljaet 10{sup 15} jev/sm{sup 3}, chto sootvetstvuet temperature poperechnyh jelektronov v 10{sup 2}-10{sup 3} jev.

4} estimula la accion inhibidora que ejercen sobre la captacion de yodo los iones hierro, cobre, cinc, cadmio, fluoruro, tiocianiato y otros, demostrando que en ella interviene la funcion de captacion. En una serie analoga de experimentos, se encontro que los compuestos sulfhidrilicos y las azidas incrementan la captacion de fluoroborato, aunque disminuyen la captacion total de yodo. Seguidamente, se demostro que la funcion de captacion es menos radiosensible que las funciones de formacion y liberacion de tiroxina. Otra aplicacion muy distinta de los iones fluoroborato marcados con {sup 18}F fue la localizacion de tumores cerebrales por exploracion direccional de coincidencias en la que se aprovecha la baja permeabilidad para estos iones de la barrera sangre- cerebro intacta. Se prepararon agentes de quelacion fluoroaromaticos marcados con {sup 18}F y se aplicaron a problemas de fisiologia de tejido oseo. Para estudiar la permeabilidad a traves de membranas biologicas, se emplearon colorantes aromaticos vitales marcados con {sup 18}F.

Por radiocromatografia sobre papel establecieron que los polimeros marcados poseeh una composicion compleja y constituyen una mezcla de por lo menos dos tipos de compuestos cualitativamente diferentes, cuyo rendimiento varia de distinta manera en funcion de la relacion entre los componentes. Un aumento del tiempo de irradiacion se traduce en un mayor rendimiento del polimero marcado. Para el sistema C{sub 6}H{sub 12}-CCl{sub 4} en fase liquida, el peso molecular del polimero se determino por difusion capilar, hallandose valores de 5 000 para el polimero de un tipo y de 500 a 1000 para el otro. Se observo tambien la formacion de un producto marcado de elevado punto de ebullicion al irradiar el CCl{sub 4} puro. Se efectuaron experimentos analogos en un sistema etileno-amoniaco en fase gaseosa a elevada presion, demostrandose que en este caso al irradiar el amoniaco anhidro puro, el principal producto marcado es el {sup 14}CH{sub 4}. Sin embargo, la adicion de pequenas cantidades de etileno hace que una gran parte -hasta el 80% - del {sup 14}C se estabilice en forma de polimero, cuyo rendimiento tambien varia considerablemente al aumentar la proporcion de etileno en el sistema, alcanzando un maximo cuando esta proporcion es del 10 al 15% de C{sub 2}H{sub 4}.

Jeti proby obrabatyvajutsja himicheskim sposobom dlja izvlechenija plutonija, kotoryj otlagaetsja jelektroliticheskim sposobom na malye diski iz nerzhavejushhej stali dlja poluchenija tonkih ''istochnikov'' s nichtozhnym samopogloshheniem al'fa-aktivnosti. Pri normal'nyh uslovijah raboty professional'no podvergajushhegosja oblucheniju personala kolichestvo aktivnosti, sobiraemoj takim obrazom, chrezvychajno malo, chto vyzyvaet neobhodimost' ochen' tochuo izmerjat' ves'ma slabye aktivnosti v poluchennyh probah. Detektory tverdogo sostojanija imejut preimushhestvo pered detektorami drugih vidov (naprimer, pered scintilljacionnymi schetchikami ili proporcional'nymi schetchikami s gazovym potokom) v tom otnoshenii, chto oni dajut vozmozhnost' sil'no ponizit' fon, chto v svoju ochered' pozvoljaet obnaruzhivat' gorazdo bolee slabuju aktivnost'. Dlja jetih izmerenij shiroko primenjajutsja dva tipa priborov s ispol'zovaniem detektorov tverdogo sostojanija. Naibolee prostoj tip oborudovanija snabzhen detektorom dlja izmerenija obshhej al'fa-aktivnosti proby. Odnako esli imejutsja eshhe drugie al'fa-aktivnye radioizotopy, to dlja opredelenija dejstvitel'nogo soderzhanija plutonija detektory tverdogo sostojanija mogut byt' ispol'zovany bolee celesoobrazno v kachestve spektrometrov; analiz amplitudy impul'sov daet vozmozhnost' otlichit' jemissiju plutonija s jenergiej 5,14 Mjev ot al'fa-jemissij drugih radioizotopov. V nastojashhee vremja ispol'zujutsja dva tipa oborudovanija s primeneniem detektorov tverdogo sostojanija dlja analiza jenergij. Naibolee prostoj iz jetih priborov vkljuchaet detektor sostojanija diametrom 20 mm, prichem na vyhode jetogo detektora imeetsja kontur, vkljuchajushhij dva diskriminatora
