    A variety of human infectious diseases are associated with the pollution of water by enteric viruses. The epidemiological data on cases associated with drinking and recreational water show Norwalk, hepatitis A and E viruses, rotavirus and enteroviruses as the etiological agents. The polymerase chain reaction (PCR) is certainly the most reliable technique available for the rapid identification of these viruses in water samples.

    Full Text Available Il saggio prende spunto da due romanzi-campione, L'educazione sentimentale di Flaubert e Lolita di Nabokov, per sviluppare una riflessione sulle trame del desiderio e dell'amore nella modernità borghese. Il quadro teorico di riferimento è il rapporto tra letteratura ed esperienza, tra la percezione del mondo e la sua trascrizione nel linguaggio, con riferimento specifico a una delle esperienze fondamentali della vita umana, la passione amorosa. Il saggio intreccia riflessioni di tipo tematico con un'analisi minuziosa degli aspetti stilistico-formali.

    Full Text Available Cosa cambia nella progettazione di un piano della ricerca quando introduciamo l'elemento-dato visuale come materiale empirico fondamentale su cui ruota l'indagine scientifico-sociale? Più specificatamente cosa cambia nel rapporto d'indicazione quando ad essere collegate al concetto generale sono delle immagini-indicatori? In questo articolo tenterò di rispondere a questo non semplice interrogativo sostenendo la tesi che nella ricerca visuale si compie, necessariamente, una semplificazione logico-semantica o meglio un accorpamento delle fasi logico-procedurali che intercorrono nel classico processo di scomposizione dei concetti teorici in referenti empirici.

    Raw water and drinking water samples collected from five treatment plants supplied by a northern Italian lake in two periods of the year (summer and winter) were studied for their mutagenicity. The water samples were concentrated on C{sub 18}Sep-Pak cartridges and the adsorbates were tested at increasing doses with the Ames test, using salmonella typhimurium TA98 and TA100 strains. Raw water samples from all treatment plants were found to contain direct-acting mutagens detectable mainly with TA98 strain. The analyses of drinking water samples after potabilization showed some interesting results. TA98 mutagenicity was reduced when ozone together with chlorine dioxide was used, but TA100 mutagenicity was increased in the summer sample; mutagenicity detectable with both strains was always reduced after chlorine dioxide disinfection; on the contrary, in all the plants using NaClO TA98 mutagenicity of winter samples increased. Therefore, disinfection of lake water with ozone and/or chlorine dioxide seems to be a suitable alternative to the use of NaClO. The results showed also the applicability of the Ames test for the evaluation of the potential mutagenic hazards caused by drinking water treatment processes.

    The use of wetland macrophytes in systems of treatment of polluted waters is an outstanding example of ecotechnology. Wetland systems are an interface between the aquatic system at risk of being polluted and the terrestrial system which is the source of pollutant substances. They are a cost-effective alternative to more conventional engineered systems to treat potential pollutant substances. They are also a part of the natural hydrological cycle and provide a ready means of making treated wastewater available for reuse. Wetland treatment systems use rooted, water-tolerant plant species and shallow, flooded or saturated soil conditions to provide various types of wastewater treatment. They are very flexible in terms of features, vegetation and performance, but the following basic types can be classified as follows: natural wetlands, constructed surface flow wetlands, constructed subsurface flow wetlands (reed beds). In this paper an outlook of the features and the functioning processes is given.

    Federambiente realised the first environmental report of national sector of environmental hygiene public utilities, in which it examined five different treatment plant typologies. Landfills, which are the most thick on the territory (about 80% of municipal solid waste is being landfilled); combustion plants for energy recovery, which will require about 7,000/10,000 billion liras investment; composting plants, allowing the transformation of nearly half of treated waste into compost. The report then explains that civil waste water exceeds industrial waste water; and that the poli-functional platform integrates different treatment typologies in a single plant: combustion, landfilling, waste water. [Italian] Federambiente ha realizzato il primo rapporto ambientale del settore nazionale dei servizi pubblici d'igiene ambientale prendendo in esame 5 tipologie impiantistiche di trattamento. Le discariche sono le piu' diffuse (viene avviato a smaltimento l'80% dei rifiuti urbani); gli impianti di termocombustione, utili per il recupero energetico per i quali bisognera' spendere dal 7000 ai 10000 miliardi; gli impianti di compostaggio che permettono di trasformare quasi la meta' dei rifiuti in compost; il rapporto spiega poi che le acque reflue degli scarichi civili sono superiori alle industriali; la piattaforma polifunzionale, infine, integra in un impianto piu' tipologie di trattamento dei rifiuti: termodistruzione, discariche, acque reflue.

Il primo è quello di illustrare, seppur brevemente, l’insieme delle teorie che hanno portato all’origine e alla affermazione della geografia dello sport, mentre il secondo cercherà di tracciare seppur a grandi linee, le emergenti linee di ricerca nell’ottica del complesso rapporto tra spazio e società. In tal modo si offriranno alcuni spunti di riflessione e nuove chiavi di lettura sul poliedrica relazione tra attività sportiva, intesa come fenomeno socio-culturale, e spazio/territorio, ormai sempre più centrale nelle più recenti politiche di pianificazione territoriale, considerando anche dell’attuale fase di deindustrializzazione che investe i nostri centri urbani.

    The efficiency of a drinking water treatment plant was investigated through the study of biochemical and microbial measures of the sand filter and the structure of the meiobenthic community. Filter and water samples were taken monthly and according to the different operation time. The efficiency of the biofilm was evaluated by the study of both structural (i.e. organic load before and after filtration, bacterial and meiobenthic density) and functional parameters (i.e. bacterial enzymatic activity and Frequency of Dividing Cells) and the analysis of the particulate organic material. The filters showed a high bacterial density and metabolic activity. The meiobenthic community, composed mainly by rotifers, nematodes and copepods, displayed a high degree of biodiversity during the studied period. The informative value of all the considered parameters and the efficiency of the filter during the operating period are discussed. [Italian] In un impianto di potabilizzazione delle acque l'analisi quali-quantitativa delle caratteristiche biochimiche e microbiche di un filtro a sabbia e del comparto acquatico associato ha permesso di valutare l'efficienza del sistema filtrante. I prelievi sono stati effettuati mensilmente in corrispondenza di differenti momenti operativi del filtro. Sono stati presi in considerazione aspetti funzionali, quali le attivita' idrolitica e duplicativa della comunita' batterica, e descrittivi (carico organico pre- e post-filtrazione, densita' batteriche e meiobentoniche). La valutazione relativa al materiale organico sospeso ha permesso di stimare l'efficienza di abbattimento attuata dal biofilm. I filtri presentano densita' batteriche molto elevate ed attivamente metabolizzanti. La comunita' meiobentonica, dominata da rotiferi, nematodi e copepodi, e' pero' sempre caratterizzata da un grado elevato di biodiversita'. Viene infine discusso il valore informativo dei diversi parametri e indici

    Full Text Available Nelle politiche linguistiche e culturali delle strategie comunitarie, il discorso sulle identità del singolo (identità nazionale, culturale, linguistica, regionale... presenta un potenziale punto d'intesa. Nel complesso delle attività che le politiche comunitarie propongono, risulta che una speciale attenzione è riservata alla tutela di alcune di esse (per esempio quella nazionale e linguistica. Si attivano quindi, simultaneamente, mezzi e conoscenze per instaurare la condivisione di un'unica cittadinanza e di una comune economia per creare una crescita culturale in un'entità organica. L'Europa è caratterizzata da culture e tradizioni simili e da una storia che accomuna tutte le nazioni che ne fanno parte. Il passato delle nazioni è contrassegnato dalla ricchezza dei valori paneuropei: valori politici, sociali, culturali, umani. La memoria, soprattutto la memoria storica, è fatta di un materiale essenziale atto a costruire e composto di elementi specifici insostituibili. Vi si trovano valori da salvaguardare e da distribuire. Uno dei vantaggi del continente Europa è il fatto di avere un passato, anche se, a tratti, conflittuale a causa delle specificità delle singole nazioni. La componente regionale e quella locale costituiscono un prezioso scrigno culturale paneuropeo le cui ricchezze emergono nel dialogo interculturale. Ci sono luoghi e tempi per cercare la creatività artistica, la curiosità scientifica, la forza intellettuale del singolo e dei gruppi che potranno far emergere nuove idee, proposte, progetti e strategie per arrivare al bene comune. La scuola è uno dei luoghi intesi come laboratori culturali. Il processo d'innovazione in atto all'interno del sistema scolastico supporta senz'altro la scuola nell'adempimento della sua funzione di operatore educativo comunitario e, allo stesso tempo, di tutore dei beni culturali e delle identità regionali.

Data were collected from November to April between the years 1976 and 1990. Aggregation sizes are included between 29 and 245 bats. A biased sex ratio in favour of males has been recognized expecially among the greatest aggregations. The abundance of each class (adult and subadult males; adult and subadult females in every aggregation has been established. Adult females is the rarest class. The strategy of females winter dispersion is analized and discussed according to its adaptive value. Riassunto Sono esposti i risultati di una ricerca sul rapporto sessi e la struttura demografica di nove aggregazioni di Rhinolophus ferrumequinum, censite da novembre ad aprile negli anni compresi tra il 1976 ed il 1990 in altrettante cavità naturali e artificiali del Lazio, Italia Centrale. Le dimensioni delle aggregazioni sono comprese tra 29 e 245 individui. Nelle aggregazioni più numerose, il rapporto sessi è nettamente a favore dei maschi. Di ciascuna categoria (maschi adulti, subadulti, femmine adulte, subadulte viene analizzata l'abbondanza in ciascuna aggregazione. Le femmine adulte costituiscono il campione più raro. Si discute il vantaggio selettivo della dispersione invernale delle femmine adulte.

    Obiettivi: l’epidemiologia delle malattie infiammatorie croniche intestinali fino ad adesso in Italia è stata poco studiata. Da alcuni studi emerge una minor incidenza di questi fenomeni nel Sud Europa rispetto al Nord Europa e agli Stati Uniti. Lo scopo di questa indagine è quello di valutare l’incidenza della Rettocolite Ulcerosa (RU e del Morbo di Crohn (MC nella popolazione dell’Azienda ULSS 17, situata nella provincia di Padova.

    Metodi: per la realizzazione di questa indagine ci si è avvalsi della collaborazione di 23 Medici di Medicina Generale (MMG operanti in 14 comuni dell’ULSS 17. I dati sono stati prelevati dal sistema informatizzato comune ai 23 MMG (Millenium, in base ai codici 555 e 556 dell’ICD9. È stato considerato il periodo di tempo 1995 - 2001. La popolazione media di riferimento è di 29.740 abitanti. Risultati: nel periodo considerato sono stati registrati in totale 45 nuovi casi, 35 casi di RU e 10 di MC. L’incidenza media della RU è stata di 16,76/100.000, quella del MC di 4,7/100.000. La RU ha avuto un’incidenza maggiore nel sesso maschile (rapporto 2:1, mentre per il MC si rileva l’opposto (rapporto 2:3. L’età media alla diagnosi per la RU è stata di 44 anni, quella del MC di 51,9. Dall’analisi temporale si evidenzia un progressivo aumento dell’incidenza del MC, mentre la RCU è più costante.

    Conclusioni: paragonando i risultati ottenuti con quelli di altre indagini condotte in Italia, l’incidenza delle malattie infiammatorie croniche intestinali è apparentemente più elevata nel territorio dell’ULSS 17. Dalla revisione della letteratura nazionale e internazionale emerge che variazioni dell’incidenza di questi fenomeni possono essere ricondotte ad un diverso accesso ai servizi sanitari, a diverse pratiche diagnostiche o alla presenza di fattori di rischio di tipo genetico o ambientale

Le sostanze stupefacenti ritenute più pericolose sono eroina 82.9%, cocaina 81.1%, allucinogeni 70%, canapa indiana 54.9%; alcol 58% e tabacco 18% sono meno pericolose. Il 15.7% ritiene che l’abitudine al fumo sia scatenata dalla socializzazione, il 15.1% dall’imitazione, il 15.4% dal piacere e dalla curiosità, l’11.1% dal sentirsi grandi, l’8% dal gusto del proibito. Il 97.1% mostra un adeguato livello di conoscenza sulle droghe e il cervello è il principale organo danneggiato (96.3%.

    Conclusioni: la conoscenza dei docenti in materia di tossicodipendenze sembra concentrata sulle droghe illegali: infatti, i rischi legati al consumo di alcol e tabacco sono sottovalutati e non sono chiari i fattori determinanti la dipendenza. Infine i docenti hanno espresso l’esigenza di aggiornamento per l’insufficiente opera di informazione e prevenzione svolta da parte delle istituzioni competenti.

However, as in much other financial regulation, the devil is in the detail. This paper considers recent patterns in global food markets and discusses some of the implications of recent moves to regulate financial activity in commodity futures markets in the US and the EU. Specific regulatory issues are considered and alternative strategies are considered.

    A feasibility study for two small hydropower plants in Osco, southern Switzerland is reported. This alpine community wants to take advantage of an elevation difference of 1500 m between a possible water catchment on a mountain stream and the location of a future hydropower plant. The report confirms the technical and economical feasibility of the project. Two series-connected plants are foreseen, with a total power of about 500 kW and a yearly expected production of 3,375,000 kWh. The project would have a positive side-effects on the public relations of the community and on education in its schools. It would prevent land slides that may happen on the steep hillsides after heavy rain fall and improve the availability of useful water resources downhill in the main valley. Federal and regional subsidies are expected. Construction work is thought to begin 2008.

    Full Text Available Il contributo presenta gli esiti della ricerca condotta da Enrico Beretta e Andrea Migliardi sulle interdipendenze tra il settore culturale italiano e il sistema produttivo del Paese; oggetto di analisi sono, in particolare, le attività culturali a contenuto non industriale – arti visive, spettacolo dal vivo, patrimonio artistico-culturale. Partendo dal presupposto che tali risorse possono in vari modi concorrere allo sviluppo, gli Autori propongono una analisi delle dimensioni e caratteristiche del settore da un punto di vista economico e gestionale-amministrativo. Le considerazioni avanzate in merito allo sfruttamento di tale risorsa e gli interventi di policy proposti per una sua corretta valorizzazione offrono un significativo contributo sotto il profilo teorico-conoscitivo e applicativo al dibattito, estremamente attuale, sul valore e le potenzialità di sviluppo, anche economico, del settore.   The paper presents the output of the research conducted by Enrico Beretta and Andrea Migliardi on the connections between the Italian cultural sector and the Country’s economy; the study focuses, in particular, on non industrial cultural activities which include the visual and performing arts and the heritage. Acknowledging their contribution to development, the Authors analyse the dimensions and characteristics of the sector both from an economic and administrative/managerial perspective. Their remarks on the current level of exploitation of such resource and the suggested policy recommendations for its enhancement represent a valuable contribution to the current debate on the value and development potentials of the sector.

    The final goal of the Project FOTO is the construction of a laboratory in a clean room for the production of active matrix which can be used to obtain Active Matrix Liquid Crystal Displays (AMLCD). The AMLCD are based on Thin Film Transistors (TFT), which can be obtained by poly-silicon (poly-Si) thin films, achieved, e.g., by irradiating films of amorphous silicon (a-Si) by ultraviolet laser radiation. In this report, are presented the results of the a-Si irradiation by using the laser-facility Hercules (excimer XeCl, l=0,308 mm) done at the ENEA Frascati Centre. The transformation of a-Si into poly-Si is commented upon the variation of the space-time characteristics of the laser pulses, of the irradiation conditions and of the characteristics of the irradiated a-Si films. [Italian] Il macro-obiettivo del Progetto FOTO e' la realizzazione di un laboratorio in camera pulita per lo sviluppo di processi atti a fabbricare matrici attive utilizzabili per ottenere schermi piatti a cristalli liquidi (AMLCD, Active Matrix Liquid Crystal Display).

The journey described in High Albania was the culmination of seven years of regular Balkan travels during which she was rewarded with insights into north Albanian life denied to all previous travellers. Unlike her other expeditions in the Balkans, her journey in northern Albania was an existential experience which deeply affected Durham’s perception of the tribespeople’s world and marked a turning point in her life. In the second part of the article some ethnographical aspects which were pointed out by Durham and are still alive in those regions are dealt with. Keywords: Balkan Studies; Cultural Studies; Ethnography; Mary Edith Durham; Albania  ITNel 2007 abbiamo deciso di organizzare una spedizione a carattere linguistico e etnogrfico nell’Albania settentrionale sulle orme dell’itinerario percorso quasi 100 anni prima dalla viaggiatrice vittoriana Mary Edith Durham, autrice dei volumi High Albania e Some Tribal Origins, Laws and Customs of the Balkans. L’itinerario descritto in High Albania coronò setti lunghi anni di esplorazioni balcaniche nel corso delle quali l’autrice riuscì a penetrare nella vita della popolazione locale, un importante esperienza che era invece mancata a tutti i precedenti viaggiatori. A differenza dagli altri viaggi precedenti nei balcani, quello nell’Albania settentrionale costituì un esperienza esistenziale che segnò profondamente la percezione della Durham del mondo delle alpi albanesi e rappresentò una svolta nella sua vita. Nella seconda parte dell’articolo sono illustrati alcuni fenomeni di carattere etnografico che furono rilevati dalla Durham e che, con nostra grande sorpresa, abbiamo potuto riscontrare sul campo nel corso della spedizione.

    The lidar fluorosensor, built at ENEA Frascati to remotely monitor the sea-water quality by collecting the water Raman back scattering and induced fluorescence from dispersed oils, suspended matter and chlorophyll, has been employed in a marine campaign in the southern Adriatic sea. To this aim, the lidar fluorosensor has been installed on a coastal guard boat and operated during the cruise. Extensive calibration measurements have been undertaken by using this system, both in laboratory and during the campaigns, to analyze sea water samples taken at several places along the Italian coasts. Absolute values of organic matter, chlorophyll concentrations have been obtained by calibrating the locally and remotely sensed lidar data with standard physical-chemical methods.

    Full Text Available Tra i fattori che agiscono sulla densità delle popolazioni di lepre quelli ambientali hanno, insieme alla pressione venatoria, gli effetti più consistenti e diretti. La specie, originaria delle praterie e delle steppe con scarsa copertura cespugliare, trova condizioni particolarmente favorevoli negli ecosistemi agricoli, soprattutto se caratterizzati da una buona variabilità colturale. Tali condizioni si riscontrano nel territorio del Parco dello Stirone, localizzato in un?area pedecollinare della bassa pianura emiliana, dove è stato condotto questo studio. Per determinare la consistenza della popolazione di lepri, nel biennio 2000-2002, sono stati effettuati censimenti in battuta su aree campione e censimenti da autovettura su percorso con sorgente di luce. I dati ottenuti con questi metodi sono stati elaborati in funzione delle caratteristiche ambientali, misurate tramite un SIT. Questo ha consentito di confrontare (one-way ANOVA e t di Student le densità rilevate nelle aree in cui il parco è stato suddiviso: sia in base alle caratteristiche morfologiche e colturali (un?area di pianura ed una a prevalenza collinare; sia in base al grado di tutela dell?area (parco vero e proprio e pre-parco. Per valutare l?influenza dell?ambiente sulla densità sono state effettuate analisi di correlazione e analisi di Regressione Multipla mentre, tramite l?Indice di preferenza di Jacobs, è stato possibile determinare la selezione dell?habitat della lepre durante le ore di alimentazione. Le densità rilevate sono state maggiori, con entrambi i metodi, nel settore di pianura e nel territorio del parco. Densità maggiori sono state rilevate nei cereali, nelle foraggere con più di 5 anni, negli incolti e negli arati.

L'articolo offre alcuni spunti di riflessione sui requisiti dei sistemi di ricerca multilingue dell'informazione giuridica, esaminando gli aspetti linguistici e concettuali che devono essere presi in considerazione nello sviluppo di tali sistemi e soffermandosi sulle problematiche della traduzione giuridica, del diritto comparato e delle tecniche di elaborazione del linguaggio naturale ai fini dell’accesso e recupero dell'informazione in un contesto distribuito. Le raccomandazioni riguardano da un lato le metodologie per stabilire equivalenze funzionali fra concetti giuridici, dall'altro possibili forme di cooperazione fra istituzioni responsabili dell'indicizzazione e distribuzione di informazioni giuridiche. Tutto ciò per garantire ad ogni cittadino di accedere all’informazione nella molteplicità di lingue in cui si manifesta e allo stesso tempo di ricercarla nella lingua preferita.

    Full Text Available Nel 1996 il Parco Naturale Adamello Brenta (Trentino, Italia, in collaborazione con la Provincia Autonoma di Trento (PAT e l'Istituto Nazionale per la Fauna Selvatica (INFS, ha avviato il Progetto Life Ursus, il cui obiettivo ultimo è ristabilire una popolazione vitale di orsi sulle Alpi Centrali. Il Progetto è stato finanziato in parte dall'Unione Europea attraverso lo strumento economico "Life Natura". Il Parco (PNAB nel 1996 ha incaricato l'INFS di realizzare uno Studio di Fattibilità che si è concentrato su un'area di 6.495 Km². Le analisi territoriali hanno permesso di valutare le caratteristiche ambientali dell'area di studio per stabilirne l'idoneità ad ospitare una popolazione di orsi. Il Modello di Valutazione Ambientale (MVA si è sviluppato considerando sia variabili "ambientali" sia "antropiche". Grazie all'utilizzo di un Sistema Informativo Territoriale (GIS è stata realizzata una carta finale nella quale sono state individuate quattro distinte aree principali: 1 aree idonee alla presenza dell'orso; 2 aree scarsamente vocate; 3 aree non idonee; 4 aree considerate a priori ambienti non utilizzabili dalla specie (rocce, zone a vegetazione rada e ghiacciai.

    What do you use water for?If someone asked you this question you would probably think right away of water for drinking. Then you would think of water for bathing, brushing teeth, flushing the toilet. Your list would get longer as you thought of water for cooking, washing the dishes, running the garbage grinder. Water for lawn watering, for play pools, for swimming pools, for washing the car and the dog. Water for washing machines and for air conditioning. You can hardly do without water for fun and pleasure—water for swimming, boating, fishing, water-skiing, and skin diving. In school or the public library, you need water to wash your hands, or to have a drink. If your home or school bursts into flames, quantities of water are needed to put it out.In fact, life to Americans is unthinkable without large supplies of fresh, clean water. If you give the matter a little thought, you will realize that people in many countries, even in our own, may suffer from disease and dirt simply because their homes are not equipped with running water. Imagine your own town if for some reason - an explosion, perhaps - water service were cut off for a week or several weeks. You would have to drive or walk to a neighboring town and bring water back in pails. Certainly if people had to carry water themselves they might not be inclined to bathe very often; washing clothes would be a real chore.Nothing can live without water. The earth is covered by water over three-fourths of its surface - water as a liquid in rivers, lakes and oceans, and water as ice and snow on the tops of high mountains and in the polar regions. Only one-quarter of our bodies is bone and muscle; the other three-fourths is made of water. We need water to live, and so do plants and animals. People and animals can live a long time without food, but without water they die in a few days. Without water, everything would die, and the world would turn into a huge desert.

    Full Text Available Negli ultimi anni la crisi economica ha colpito con forza l’intero Sud Europa, esasperando dinamiche di impoverimento e precarizzazione di lungo periodo. In Italia e in Spagna, tra gli altri, si è assistito a mobilitazioni contro la precarietà lavorativa e esistenziale. In questo contributo vengono presi in esame i movimenti contro la precarietà in Italia e in Spagna, allo scopo di analizzarne la genesi, gli sviluppi e le prospettive future. In particolare, il paper si concentra sulle rivendicazioni dei movimenti, l’autorappresentazione, la struttura delle alleanze e le strategie di azione, mettendo in luce i risultati delle proteste e i repertori discorsivi e di azione. | In the last years, the economic crisis heavily hit all the Southern European States, exacerbating well rooted dynamics of impoverishment and precarization. In Italy and Spain, among others, social movements against labour and existential precarity developed and took the streets, receiving a high degree of media attention. In this paper we focus on the movements against precarity in Italy and Spain, in order to analyse their genesis, developments, and future opportunities. In particular, the paper focuses on the movements’ claims, their self-representation, the structure of alliances and their strategies of action, highlighting the results of the protests and the repertories of discourse and action.

    2010-01-01

    Full Text Available The relationship between man and nature denotes many problems in Spinoza’s context, where necessity plays an essential role. This essay tries to define the status of the possibility and its relationship to the natural necessity. The man-nature relationship reveals itself as conflictual space, where the human being faces the possibility of death and looks for the possibility of survival. The political action and the constitution of community offer an answer to the uncertainty of human position. Community is not an artificial monster; it is rather the adequate place where the human right and the human power express themselves. Nature and culture are not dissociated, since the society affirms the natural potentia of the human being and that of the multitude.

E’ innegabile che essa sia un’area di sicuro fascino ed interesse perché, nonostante le molte ricerche medico - biologiche - psicologiche - sociologiche effettuate in questo ambito, i disturbi mentali rimangono tuttora avvolti da un alone di mistero. Questo da un lato porta le persone a sottovalutare il problema della salute mentale, a volerlo nascondere perché non si sa come affrontarlo, come gestirlo, come viverlo. Dall’altro lato l’area della salute mentale pone in essere molte sfide agli operatori ed a tutti i soggetti della comunità, che a vario titolo sono coinvolti. E’ il cambiamento di cultura, il vero motore dei mutamenti radicali, epocali, innovativi: a mio avviso e dalla prima esperienza vissuta ho potuto notare che andrebbe promossa e diffusa una cultura, (non tanto o non solo specifica della salute mentale e non solo fra gli operatori istituzionali della partecipazione, della promozione e dell’empowerment delle persone che presentano disturbi mentali.

    demographic and income patterns should be adequately taken into account and, on the other side, water information campaigns should be adopted in order to increase awareness of water consumption effects. [Italian] Questo lavoro stima, per un panel di comuni lombardi, la funzione di domanda d'acqua domestica sia in contesto statico che dinamico. Per il primo, quello statico, ci concentriamo sulI'aspetto della negoziazione del prezzo e sulle sue implicazioni sulle stime della domanda. Per il secondo, quello dinamico, si studiano le determinanti della domanda d'acqua e l'elasticita di lungo periodo della stessa rispetto al prezzo. I dati relativi al periodo analizzato mostrano una riduzione della popolazione e dei consumi aggregati mentre segnalano un leggero incremento del consumo per utenza. I risultati delle stime, coerenti con la letteratura, indicano che la domanda d'acqua e inelastica, almeno nel breve periodo, rispetto al prezzo. L'evoluzione dei consumi sembra perpetuarsi secondo quanto avvenuto in passato, indicando una sorta di inerzia o path dependency. Le policy, a nostro avviso, dovrebbero tenere conto maggiormente di cio che, secondo i nostri risultati, influenza i consumi, come la struttura demografica e il reddito. Inoltre, per favorire un consumo consapevole, sembra indispensabile intensificare l'informazione sulle condizioni di fornitura e sulle possibili implicazioni dei consumi idrici.

    Full Text Available Nel mite totalitarismo che stende il suo velo melenso su delle masse inquiete, si sa che i diversi tecnocrati rinsaldano il loro potere alimentando il timore. Ciò che non è molto complicato, tanto il timore dell'ombra, il timore della sua ombra lavora tutto su ciascuno. Se si deve caratterizzare l'epoca, è perfetto il termine di codardia generalizzata che viene immediatamente allo spirito. È noto che il virus dell’influenza aviaria non può contagiare l’uomo che da un contatto diretto e prolungato. Per esempio, bere l’acqua di una palude infettata da escrementi di uccelli contaminati o fornicare con un pollo afflitto da questo male. Ugualmente, il pericolo di pandemia non potrebbe arrivare che da congiunzione con l’influenza umana. Così, i virologi considerano che sarebbero necessarie centinaia di persone infettate per avere un pericolo reale d’infezione generale. Come si vede, il rischio è grande! Ma non è questo il problema. È sufficiente, per noi tecnocrati, che l’immaginario dell’insicurezza sia lì. Essi vi trovano una ragione d’essere. Possono, sapientemente, giocare le utilità. Si sa che di qualsiasi tempo, è puntando su un'angoscia diffusa che i diversi poteri hanno fatto accomodare la loro legittimità. In realtà ciò che è da prendere seriamente, sono le isterie collettive. La caduta spettacolare del consumo di pollame di qualsiasi tipo lo testimonia. Ricordiamoci anche che non è lontano il tempo dove lo stesso sospetto incombeva sulla carne bovina! Bando agli scherzi! Attualizziamo l’apologo. Così l'emozione causata dal doppio scandalo che colpirà il CNRS non manca di suscitare inquietudini e interrogativi. Naturalmente in termini di epidemiologia. Preoccupazioni quanto alla salute mentale dell’ambiente sociologico capace di far petizioni mescolando, senza accigliarsi, la gallina ed il bue, la parità e il problema di una nomina considerata come provocatrice. Preoccupazioni sulla semplice moralità di questo “ambiente”.

    The author inspects the telescopic observations performed by Galileo Galilei beginning since 1609. In the first part he examines the attribution to Galileo of the instruments now in Florence in the Istituto e Museo di Storia della Scienza (IMSS). In the second part he considers the observative and optical analyses realized in this century about the telescopes. In the final part he exposes the observations carried out with an instrument very similar to those Galileo had, the "Project STAR" Scope. The author concludes the IMSS instruments represent very well those used by Galileo and, in particular, they are among the best utilized by Italian scientists. The author is also convinced since 1612 Galileo employed a telescope with 5" resolution power.

    Agriculture is the largest freshwater consumer, accounting for 70% of the world's water withdrawal. Water footprints (WFs) are being increasingly used to indicate the impacts of water use by production systems. A new methodology to assess WF of wine was developed in the framework of the V.I.V.A. project (Valutazione Impatto Viticoltura sull'Ambiente), launched by the Italian Ministry for the Environment in 2011 to improve the Italian wine sector's sustainability. The new methodology has been developed that enables different vines from the same winery to be compared. This was achieved by calculating the gray water footprint, following Tier III approach proposed by Hoekstra et al. (2011). The impact of water use during the life cycle of grape-wine production was assessed for six different wines from the same winery in Sicily, Italy using both the newly developed methodology (V.I.V.A.) and the classical methodology proposed by the Water Footprint Network (WFN). In all cases green water was the largest contributor to WF, but the new methodology also detected differences between vines of the same winery. Furthermore, V.I.V.A. methodology assesses water body contamination by pesticides application whereas the WFN methodology considers just fertilization. This fact ended highlights the highest WF of vineyard 4 calculated by V.I.V.A. if compared with the WF calculated with WFN methodology. Comparing the WF of wine produced with grapes from the six different wines, the factors most greatly influencing the results obtained in this study were: distance from the water body, fertilization rate, amount and eco-toxicological behavior of the active ingredients used.

    In the present paper, the net long-wave radiation balance of the water-air environmental systems is analysed on the base of several semi-empirical approaches. Various theoretical models of infrared atmospheric radiation are reviewed. Factors, affecting their behavior are considered. Special attention is paid to physical conditions under which those models are applicable. Atmospheric and net infrared radiation fluxes are computed and compared under clear and cloudy sky. Results are presented in graphical form. Conclusions are made on the applicability of models considered for evaluating infrared radiation fluxes in environmental conditions of Central Italy. On the base of present analysis Anderson's model is chosen for future calculations of heat budget of lakes in Central Italy. [Italian] Nel presente rapporto viene analizzato il bilancio della radiazione infrarossa per i sistemi acquatici sulla base di alcune formule semi-empiriche. Vengono esaminati vari modelli della radiazione infrarossa atmosferica e i fattori che la influenzano. I flussi di radiazione infrarossa dall'atmosfera in condizioni di cielo sereno e nuvoloso vengono calcolati e confrontati. L'analisi dell'applicabilita' dei modelli considerati per il calcolo dei flussi di radiazione infrarossa in corrispondenza delle condizioni ambientali dell'Italia centrale suggerisce di scegliere il modello di Anderson per la valutazione del bilancio calorico die laghi vulcanici.

    Full Text Available A Marie Darrieussecq è successo qualcosa di strano. Non è il fatto di essere nata in Francia, a Bayonne, nel 1969. Né di essere una scrittrice (oltre che una studiosa di letteratura e una psicanalista, che ha pubblicato fiction, racconti autobiografici, saggi letterari. Questo non è così strano. Lo è invece il fatto che metà dei suoi romanzi siano stati considerati, da lettori diversi e soprattutto da altri scrittori, prodotti di «imitazione», «copia», «plagio psichico», o addirittura di «sottrazione di manoscritto»

    Full Text Available This paper shows how to describe the human-machine interaction through semiotic metalanguage. The machine is seen as an addresser, which modalizes the action of the subject through deontic and/or epistemic operators. This way, complex human-machine devices can be deconstructed as chains of modal enunciations that constitute disciplinary apparatus, focusing on the immanent structure of jobs, in a way that seems to differ from a phenomenological point of view. These devices try to realize a perfect hierarchical order in which the machine is the constant and the human being is the variable, thus revealing their bio-political relevance. The economic crisis corresponds, to a large extent, to stricter disciplinary politics implemented in order to raise the rate of exploitation of labour.

    Full Text Available Non è facile parlare di lavoro in modo oggettivo, soprattutto se si parla del proprio e in un momento storico così critico a livello economico. Quando mi è stato chiesto se volevo dare un mio contributo a questo numero di Magma ho accettato per due motivi piuttosto istintivi: il primo è che, seppur in modo trasversale, ho vissuto e percepito la precarietà, e in poco meno di un anno la qualità della mia vita è peggiorata in relazione alla situazione che si era venuta a creare sul posto di lavoro, e per questo sento l’argomento vicino. Il secondo motivo, in parte conseguenza del primo, è che mi piacerebbe se questo mio contributo potesse essere d’aiuto a chi sta vivendo problemi legati al lavoro simili ai miei, e magari da alcune riflessioni cui sono arrivato dopo la mia personale esperienza possa trovare uno o più spunti per provare a risolvere le difficoltà che vive a causa del lavoro.

    Full Text Available The Italian revolutionary syndicalism influenced the formation of the fascist ideology. For a long time, it had been a link between fascism and revolutionary circles in italy, useful for both the rise of fascist power during the early stages, and the maintaining of a revolutionary face during its authoritarian phase. But at the same time, the revolutionary syndicalism lost much of its own identity, getting lost in paths which would have contradicted some of his ideal cornerstones.

    Full Text Available

    I pesci, al momento della pesca, risultano più o meno inquinati in relazione alla qualità delle acque in cui vivono e al tipo di manipolazione che subiscono; tale contaminazione batterica oscilla tra 103ufc/cm2 di superficie corporea e tra 102-109 ufc/gr di intestino. Successivamente, si assiste ad una modificazione quali-quantitativa della microflora iniziale e molti batteri (spoilage flora partecipano attivamente al processo di deterioramento.

    Essenzialmente, la contaminazione microbica del pesce, determina processi proteolitici, sebbene, soprattutto nella fase iniziale, siano i composti azotati non proteici ad essere metabolizzati dai microrganismi. Si formano così composti volatili come trimetilammina, dimetilammina, ammoniaca, che impartiscono odori anomali e associati al deterioramento. Scopo del nostro lavoro è stato quello di quantificare, in campioni di orate (Sparus aurata provenienti da un allevamento di tipo intensivo (impianto a vasche e in quelle provenienti da un allevamento di tipo semintensivo, alcune specie batteriche coinvolte nei processi di deterioramento in condizioni di refrigerazione. Su campioni di pesce appena pescati (conservati e trasportati in ghiaccio, è stata eseguita una cinetica di crescita microbica (tempo 0, 3 e 6 giorni alla temperatura di 4°C su sezioni di pelle e muscolo, visceri e branchie. Sono stati valutati i seguenti parametri microbiologici: conta microbica totale, Pseudomonadaceae, Shewanella putrefaciens ed Enterobacteriaceae totali. Pur partendo da concentrazioni iniziali non significativamente diverse le orate provenienti da allevamento di tipo intensivo hanno evidenziato cariche microbiche più alte (superiori a 107ufc/g a partire dal 3° giorno di conservazione per tutti i parametri considerati.

    Le orate provenienti da allevamento semintensivo sono risultate quindi microbiologicamente più stabili rispetto a quelle provenienti da allevamento intensivo. Pseudomonas fluorescens e Pseudomonas putida sono risultate le specie più abbondanti. Negli esemplari provenienti da allevamento intensivo sono state isolate anche Pseudomonas aeruginosa e Pseudomonas pseudomallei: l’isolamento di queste due specie fa ipotizzare una contaminazione da acque reflue nel sistema di alimentazione delle vasche dell’impianto di allevamento.

Una metafora affascinante che guida nella riflessione sulla dimensione fisica, tattile, intimamente sensibile dell’edificio scolastico e di tutti i suoi materiali. Specchio dell’innovazione della relazione tra insegnante-allievo e sapere, il corpo si collega direttamente a come la scuola incarna l’approccio pedagogico e gli spazi (l’architettura dell’edificio. Come il corpo, la scuola ha la capacità di esprimersi con la sua statura, la sua presenza. Si propone l’impiego della metafora della scuola come un corpo, catturando alcune declinazioni fisiche ed espressive degli edifici scolastici (dalla sua ossatura, al suo metabolismo, alla sua empatia, per non parlare di quanto il corpo assorbe e reagisce con tutti i cinque sensi in modo da costruire un ponte tra pedagogia e architettura lontano dal lessico consolidato tra tutte e due le discipline.

  14. Villena e Febrer sulle soglie dell’Inferno

    Directory of Open Access Journals (Sweden)

    Anna Benvenuti

    2012-01-01

    Full Text Available Lo studio prende le mosse dalla contemporanea apparizione di due traduzioni della Divina Commedia nella Penisola Iberica: la prima in prosa castigliana, per opera di Enrique de Villena, nel 1428, la seconda in endecasillabi catalani, firmata da Andreu Febrer nel 1429. Dopo aver analizzato la genesi delle due versioni, sono stati messi in evidenza i metodi impiegati dai due traduttori, che risultano strettamente dipendenti dal diverso obiettivo che si erano prefissati: Febrer pare intenzionato a creare un’opera letteraria in qualche modo autonoma, mentre lo scopo della traduzione spagnola sembra essere stato quello di fornire un testo a fronte per facilitare la lettura dell’originale con un "supporto". Il confronto delle soluzioni via via adottate permette di far emergere i possibili contatti tra Villena e Febrer durante l’elaborazione delle loro opere, ipotizzabile a partire dalla comune formazione giovanile nell’ambito della corte catalana. Data la vastità delle opere, lo studio è stato condotto prendendo come punto di riferimento il canto III dell’Inferno e, più in generale, la prima cantica. Alla luce di quanto analizzato, sembra plausibile ipotizzare che la versione castigliana poté servire in qualche caso a Febrer e non viceversa. The first translations into a vernacular language of Dante’s Divina Commedia were carried out in 1428 and 1429: the first, in Castilian prose, signed by Enrique de Villena; the second in Catalan verse, that is, hendecasyllabic tercets as in the original text, by Andreu Febrer. My aim in this study is to outline a short depiction of the cultural moment where they both dwelled in order to understand the relationship between their versions, so as to subsequently undertake an approach to both texts to assess the modus operandi they followed. Finally, I try to substantiate the hypothesis of a possible contact between both writers while each of them was at work on his translation. As far as Febrer is concerned, his aim seems to have been to create a somehow autonomous literary work, while the purpose of the Spanish translation appears to have been to present a parallel text as a support for an easier reading of the original one. Since their aims are not the same, it follows that the outcome of their work cannot be compared from the stylistic point of view. Nevertheless, if we do compare them, we may understand more clearly the creative stance of both authors and, lastly, identify out the possible contacts between Villena and Febrer while they were at work on their versions. At the end of a first appraisal of the texts under examination it is possible to assume that, even if the Catalan poet knew Italian better, his translation was probably of no use to Villena precisely because of the excessive liberties the former took with the text and also due to his reiterated resorting to Italianisms and Occitanisms. On the contrary, the text in Spanish, precisely due to its different purpose, is far more likely to have been of some use to Febrer’s work. My impression, supported by a few examples, is that Febrer somehow managed to read his colleague’s work and that he in some instances drew on it. Given the extent of their work, to carry out my study I have decided to take the Third Canto of the Inferno, and especially the first stanza, as my point of reference.

According to this law all Italian taxpayers can participate to a sort of ‘poll’ to allocate 0.008 of their income tax (IRPEF to the either the Catholic Church or the State by signing under one of the other in the tax form. The entire fund (i.e. the overall amount of 0,008 of the IRPEF will then be divided proportionally amongst the choices selected by the tax payer who signed to give 0.008 of their taxes to specific institutions (e.g. the Catholic Church, the State, etc. In doing so, even the tax payers who did not choose any denomination will end up funding one according to the selection made by those who did sign to give their taxes to a religious group or to the State. In this essay the Author analyses some juridical aspects of that particular funding system which represents an important feature of the discipline regulating the relationship between State and Churches, including religious denominations other than Catholicism.

L’analisi delle singole figure dei Giganti, tuttavia non avulse dal proprio contesto monumentale e storico-artistico, conduce a una classificazione tipologica in grado di illuminare sulla tradizione, la circolazione e la persistenza, fino alla citazione puntuale, degli schemi iconografici e delle soluzioni compositive impiegati nella lunga storia della Gigantomachia, con lo scopo precipuo di appurare quanto di quel legame sia possibile rintracciare attraverso la lettura e il confronto iconografici dei due monumenti.

    Full Text Available Ormai i lettori di file mp3 - l’algoritmo di compressione per i brani musicali digitalizzati - sono entrati nel ventaglio delle tecnologie di uso comune, soprattutto per quanto concerne l’universo giovanile. All’interno dell’infinita varietà di marche e modelli però, possiamo sostenere con buona sicurezza che l’iPod, il lettore mp3 della Apple, ha saputo conquistarsi una buona fetta di mercato. I motivi del suo successo commerciale si legano a diversi elementi, tra i quali non possiamo far a meno di citare la capacità dell’iPod di assorbire le interpretazioni simboliche proposte dai suoi fruitori, un processo quasi sconosciuto agli altri lettori mp3. L’iPod non viene inteso sic et simpliciter come un oggetto con relativa funzione ma anche come simbolo, un contenitore di significati mutevoli che gli individui utilizzano per comunicare ai propri simili la loro solidarietà nei confronti del “pensiero Apple”. Ma non solo: se tutto ciò fosse vero, potremmo anche immaginare questo lettore mp3 investito da valori estetici a tal punto da trasfigurarsi in orpello da abbinare con il soprabito. È possibile, quindi, pensare all’iPod non solo come lettore di file mp3 ma anche come un qualsiasi monile, gioiello e/o accessorio del proprio abbigliamento? Questa domanda rappresenta la base della ricerca che verrà approfondita nel seguente saggio, un lavoro che tramite l’utilizzo di tecniche appartenenti all’universo della ricerca qualitativa cerca di dare possibili risposte - mai definitive - ai precedenti quesiti.

    Full Text Available Following Even-Zohar’s (1979ff. theoretical framework, particularly as regards his theory of ‘transfer’ (i.e. a text which was created in a cultural system A is re-created in a cultural system B, this essay analyses some modern cinematic and theatrical adaptations of the Old English epic poem Beowulf. Even-Zohar’s theory of transfer has been seldom used in previous research dealing with intersemiotic translation, some notable exceptions being Cattrysse (1992, Remael (2000, and Weissbrod (2004, (2006. After discussing the peculiarities of the processes of transfer applied to medieval works, the reasons why Beowulf can still nowadays play the role of an imported good and, through its rewrites, is integrated into the home repertoire of a contemporary cultural polysystem will be discussed, along with the consequences generated by this integration. Furthermore, the network of relations between the state of the home system, the nature of the transference activity, and the relations between power and market with respect to the ideological component of the process of tranfer will be taken into consideration. To this end, the notions of ‘capital’ elaborated by Bourdieu (1980, as well as that of ‘norm’ put forth by Toury ([1978] 1995 will be used. The results achieved in this study are in line with the claim that peculiar processes affecting specific form of intersemiotic translation can be detected only within the framework of a general theory of transfer.

    Full Text Available http://dx.doi.org/10.5007/1677-2954.2013v12n2p227 Abstract: in this article I claim that in a Kantian perspective the rational capacity of human beings can be considered as the core of moral life and, more generally, of human experience. On this basis I try to answer the following question: how should we conceive the value of life when the specifically human features are missing? More precisely, I suggest an antinaturalistic interpretation of Kantian theory concerning duties to oneself: my aim is to show that the ends of nature cannot work as a criterion for judging the correct use of our own dispositions. This reading can be applied to Kant’s reflections on suicide, stressing that the Kantian view is a quite complex one and requires therefore careful consideration. Indeed, Kant does not conceive life a merely biological concept; this is the reason why I would like to point out that the Kantian perspective on these topics can provide an interesting conceptual background for the contemporary debate on end-of-life questions.Key-words: Kant, antinaturalism, natural teleology, suicide, end-of-life.

    Full Text Available Il presente articolo riflette sul radicamento della violenza di genere contro le donne nel sistema di relazione tra i sessi. L'articolo è suddiviso in due parti. Nella prima parte si riflette sui significati della violenza di genere dentro il sistema di relazione tra i sessi, sulle sfasature che i profondi mutamenti degli ultimi decenni mostrano tra riferimenti valoriali e pratiche sociali. Nella seconda parte si presentano i risultati di un'indagine che ha per oggetto la violenza esperita dalle studentesse universitarie. Si tratta di una ricerca europea di cui qui si approfondisce il caso dell'università di Urbino e del suo territorio. Dall'indagine proviene una conferma dell'esistenza di un fenomeno capillarmente diffuso, che colpisce le donne anche durante la vita universitaria. La violenza esiste e si insinua nelle relazioni più prossime, nei luoghi della vita quotidiana, ma il non detto e l'indicibile rimandano ad un fenomeno ben più ampio di quanto emerso.RésuméDans cet article l’auteur réfléchit sur l’enracinement de la violence de genre contre les femmes dans le cadre des relations entre les sexes.

    Full Text Available Basandosi sulle evidenze relative al rapporto tra tecnologia e apprendimento e sul recente rapporto OCSE riguardante il Piano Nazionale Scuola Digitale, l’autore riflette sui criteri che devono orientare le politiche innovative, ispirati a sostenibilità, ottimizzazione dell’impatto educativo, sottolineando anche la necessità di finalizzare meglio l’impiego delle tecnologie verso specifici obiettivi. Viene ricordato come storicamente si tenda a sovrastimare l’effetto positivo delle tecnologie sull’apprendimento; la ricerca ha invece rilevato i limiti della loro efficacia (da ricercare in determinate aree e la rilevanza del rischio del sovraccarico cognitivo che la loro introduzione può comportare. Si propongono alcuni suggerimenti per i decisori scolastici rispondendo alle due domande “Quali criteri per la politica tecnologica?”, “In che modo usare le tecnologie per apprendere a scuola?”.

  16. Response of durum wheat to water variability under climate change scenarios in southern Sardinia

    Durum wheat is the most important C3 rainfed crop in southern Sardinia, Italy and is highly vulnerable to climate variability. This region has experienced severe drought conditions and problems of competing water demands during the last decades. Within the framework of European (1) and Regional (2) research projects, a study was conducted to evaluate the effects of increased maximum temperature and high rainfall variability on durum wheat yield, as part of an effort to devise strategies for water management and adaptation at the field and catchment scales in southern Sardinia. Towards this goal, the AquaCrop model was calibrated and its predictive performance was tested in the period from 1995 to 2012 using daily meteorological data and durum wheat (CV Creso) yield measurements from the experimental fields of the Agris Research Agency in Ussana (Sardinia, Italy). During the verification period, the model showed a good performance with a significant correlation between observed and simulated yield for durum wheat and a very good estimation of the water stress conditions during the drought period in 1995. Next, four future scenarios of climate change were simulated with AquaCrop to predict wheat yield responses and to investigate water availability for rainfed and irrigated crops for the 30-year periods 2011-2040, 2041-2070, and 2071-2100. The simulated future scenarios show potential improved productivity arising from the increased CO2 concentration. This positive outlook is however tempered by increased uncertainty and fluctuations in rainfall during the fall and early winter periods (September-December). The possible tradeoffs between these factors, as well as the expected negative effects of increased maximum temperatures, are being further examined.

    The sorption of boron from boric acid water solution by impregnated activated carbon has been studied. Barium, calcium, mannitol, tartaric acid and citric acid were used as chemical active materials. All processes were performed in a chromatographic continuous system at 22{sup 0} C. Experimental results show that activated carbon impregnated with mannitol is effective in removing boron from water. The separation of boron from the wastewater from a factory for producing enameled dishes by activated carbon impregnated with mannitol was also performed. Two models have been applied to describe published and new data on boron sorption by impregnated activated carbon. Both of them are based on the analysis of boron concentration response to the step input function. This led to a mathematical model that quite successfully described impregnation effects on adsorption capacities. [Italian] E' stato studiato l'assorbimento del boro, mediante carbone attivo impregnato, da soluzioni acquose di acido borico. Quali materiali chimici attivi sono stati utilizzati: bario, calcio, mannitolo, acido tartarico ed acido citrico. Tutti i processi sono stati condotti in un sistema cromatografico continuo a 22{sup 0}C. I risultati sperimentali mostrano che il carbone attivo impregnato con mannitolo e' efficace nella rimozione del boro dall'acqua. E' anche stata effettuata la separazione del boro da acque di scarico di un'industria per la produzione di piatti smaltati mediante carbone attivo impregnato con mannitolo. Sono stati applicati due modelli per descrivere i risultati, pubblicati e nuovi, dell'assorbimento del boro mediante carbone attivo impregnato. Entrambi sono basati sull'analisi della risposta alla concentrazione di boro successivamente incrementata a stadi. Cio' porta ad un modello matematico che descrive abbastanza soddisfacentemente gli effetti dell'impregnazione sulla capacita' di assorbimento.

    This article examines the implementation of Peru’s new water law and discusses how it produces new forms of water citizenship. Inspired by the global paradigm of “integrated water resources management,” the law aims to include all citizens in the management of the country’s water resources...... by embracing a “new water culture.” We ask what forms of water citizenship emerge from the new water law and how they engage with local water practices and affect existing relations of inequality. We answer these questions ethnographically by comparing previous water legislation and how the new law currently...... is negotiated and contested in three localities in Peru’s southern highlands. We argue that the law creates a new water culture that views water as a substance that is measurable, quantifiable, and taxable, but that it neglects other ways of valuing water. We conclude that water citizenship emerges from...

    The authors focus on water resources and the use of mineral waters in human nutrition, especially in the different stages of life, in physical activity and in the presence of some morbid conditions. Mineral water is characterized by its purity at source, its content in minerals, trace elements and other constituents, its conservation and its healing properties recognized by the Ministry of Health after clinical and pharmacological trials. Based on total salt content in grams after evaporation of 1l mineral water dried at 180 degrees C (dry residues), mineral waters can be classified as: waters with a very low mineral content, waters low in mineral content, waters with a medium mineral content, and strongly mineralized waters. Based on ion composition mineral waters can be classified as: bicarbonate waters, sulfate waters, sodium chloride or saltwater, sulfuric waters. Based on biological activity mineral waters can be classified as: diuretic waters, cathartic waters, waters with antiphlogistic properties. Instructions for use, doses, and current regulations are included.

  18. Wasted waters.

    Science.gov (United States)

    Niemczynowicz, J

    1996-11-01

    This article presents the increasing mismanagement of water as a result of increasing delivery of water volume, water pollution, and water wasting. One example of water mismanagement is irrigation, through which 67% of water is withdrawn from the hydrological cycle. In addition, reports from European communities reveal that pesticides from agriculture worsen the existing underground pollution. Furthermore, a 25% drop in land productivity was observed in Africa due to erosion, salinization, water logging, and desertification. Also, 23% of withdrawn water goes to industries, which are the major polluters. Since 1900 about 250,000 tons of cadmium have been produced worldwide, which eventually enter and harm the aquatic and terrestrial ecosystems. Moreover, high mercury levels were observed in Malaysia's Kelang River in the late 1980s, and river pollution in Thailand and Malaysia is recorded to be 30-100 times higher than accepted levels. Aside from that, the human race must also understand that there is a connection between water scarcity and water quality. When there is water pollution, it is expected that many people will suffer diarrheal diseases and intestinal parasite infections, which will further increase the mortality rate to 3.3 million per year. Realizing the severity of the problem, it is suggested that the human race must learn to recycle water like stormwater to prevent scarcity with drinking water.

    2014-06-15

    Branding is a key strategy widely used in commercial marketing to make products more attractive to consumers. With the exception of bottled water, branding has largely not been adopted in the water context although public acceptance is critical to the implementation of water augmentation projects. Based on responses from 6247 study participants collected between 2009 and 2012, this study shows that (1) different kinds of water - specifically recycled water, desalinated water, tap water and rainwater from personal rainwater tanks - are each perceived very differently by the public, (2) external events out of the control of water managers, such as serious droughts or floods, had a minimal effect on people's perceptions of water, (3) perceptions of water were stable over time, and (4) certain water attributes are anticipated to be more effective to use in public communication campaigns aiming at increasing public acceptance for drinking purposes. The results from this study can be used by a diverse range of water stakeholders to increase public acceptance and adoption of water from alternative sources. Copyright © 2014 The Authors.

    Full Text Available Because of their relative autonomy from the cultural industry, German films of the Twenties are an interesting field to try an analysis on the psychologic attitudes of a society or an age. The themes of films from this era will be examined in this essay: the frequent representation of tragic stories, the role of repression, wich the film has, the construction of monumental atmospheres. The cardinal skill of this work is in facts to show how films affected everyone´s aesthetic reception at those time, as it liquidates every association with the past and prepares an apperception, that has been useful for authoritarian systems.

    Full Text Available Theatre takes place in a concrete territorial dimension. Theatre springs from the territory, and at theend goes back to it, within a circular movement between, on one side, the opportunities and thelimitations imposed by the places where the performances take place and, on the other side, theoutcomes that these theatrical activities produce in the socially shared perception of spaces. Therelationship between theatre and places is here approached through the analysis of the processes of localization, the opposition between closed spaces and open ones, the intertwining of the temporaland the spatial dimension. In the second part of the article, the author concentrates on therelationship between theatre and landscape. These two elements, as stated both by historians (suchas Cruciani and Serino and geographers (such as Turri share many characteristics. At the end, theauthor explains the potentialities offered by theatrical actions to improve “territorial education”.

    This article explores the potential construction of a water reservoir in Peru’s Cordillera Blanca. Proposed by a peasant group, it would have served important productive purposes but have its intake within the perimeter of a national park. Thus, different notions about water and landscape emerge...... in the encounters between place-based practices and state-sponsored conservation efforts. Empirically tracing the efforts to construct the reservoir, the analytical focus of the article is on how different ways of knowing water within a particular landscape conjure and collide in the process. It is argued...... that the movement of water extends itself beyond the physical properties of the reservoir and irrigation channels as these are produced in encounters between different notions of the role of water in the landscape....

  14. Groundwater Waters

    1999-10-01

    Full Text Available The groundwaters released through springs constituted a basic element for the survival and progressive development of human beings. Man came to learn how to take better advantage of these waters by digging wells, irrigation channels, and galleries. Nevertheless, these activities do not require cooperation nor the collective agreement of relatively large groups of people, as in the case of creating the necessary structures to take advantage of the resources of surfacewaters. The construction and operation of these structures was a powerful factor in the birth of an urban or civil society – the designated water civilizations. The difference between people taking advantage of groundwater, quasi-individually, and those of surface water, where people work in a group, has continued to the present day. Whereas earlier, this difference did not bring about any special problems, the technological advances of this century, especially theturbine pump, have led to a spectacular increase in the use of roundwater. This advance has significantly contributed to reducing hunger in the world and has provided potable water in developing countries. However, the almost generalized lack of planning and control in the exploitation of these groundwaters reflects that they are little or badly understood by the managers of water policy in almost every country. As such, problems have occurred which have often become exaggerated, giving rise to water-myths. These problems, though, should be addressed if the aim is the sustainable usage of surface water as well as groundwater. To counter any misconceptions and to seek solutions to the problems, distinct plans of action can be highlighted: educating the public; fomenting a system of participative management and decisive support for the communities of users of subterranean waters; integrating a sufficient number of experts in hydrology in the various water management organizations;and assuring transparency of the data on

    Full Text Available In a recent article, F. Modigliani and T. Padoa-Schioppa argued that indexing at 100% with frequent wage adjustments rises the general rate of inflation associated with a given gap between the price level desired by businesses and that compatible with the real bargaining wage of workers. The present work compares this examination of an economy with wages indexed at 100% with an alternative situation in which indexing is absent or not effective in protecting wages. It is shown that in the presence of expectations of inflation incorporated into the determination of wage rates: 1 if there is a gap between the price level desired by businesses and that compatible with the real wage desired by workers, inflation is growing rather than stable as in the M.-P.S. model; 2 the "return" of inflation through restrictive maneuvers is accomplished with greater difficulty and involves greater time and costs than in the M.-P.S. model.

    A compelling visualization is captivating, beautiful and narrative. Here we show how melding the skills of computer graphics, art, statistics, and environmental modeling can be used to generate innovative, attractive and very informative visualizations. We focus on the topic of visualizing forecasts and measurements of water (water level, waves, currents, density, and salinity). For the field of computer graphics and arts, water is an important topic because it occurs in many natural scenes. For environmental modeling and statistics, water is an important topic because the water is essential for transport, a healthy environment, fruitful agriculture, and a safe environment.The different disciplines take different approaches to visualizing water. In computer graphics, one focusses on creating water as realistic looking as possible. The focus on realistic perception (versus the focus on the physical balance pursued by environmental scientists) resulted in fascinating renderings, as seen in recent games and movies. Visualization techniques for statistical results have benefited from the advancement in design and journalism, resulting in enthralling infographics. The field of environmental modeling has absorbed advances in contemporary cartography as seen in the latest interactive data-driven maps. We systematically review the design emerging types of water visualizations. The examples that we analyze range from dynamically animated forecasts, interactive paintings, infographics, modern cartography to web-based photorealistic rendering. By characterizing the intended audience, the design choices, the scales (e.g. time, space), and the explorability we provide a set of guidelines and genres. The unique contributions of the different fields show how the innovations in the current state of the art of water visualization have benefited from inter-disciplinary collaborations.

    The Vision Catalyst Purifier employs the basic technology developed by NASA to purify water aboard the Apollo spacecraft. However, it also uses an "erosion" technique. The purifier kills bacteria, viruses, and algae by "catalytic corrosion." A cartridge contains a silver-impregnated alumina bed with a large surface area. The catalyst bed converts oxygen in a pool of water to its most oxidative state, killing over 99 percent of the bacteria within five seconds. The cartridge also releases into the pool low levels of ionic silver and copper through a controlled process of erosion. Because the water becomes electrochemically active, no electricity is required.

    Fibers constitute the backbone of modern communication and are used in laser surgeries; fibers also genarate coherent X-ray, guided-sound and supercontinuum. In contrast, fibers for capillary oscillations, which are unique to liquids, were rarely considered in optofluidics. Here we fabricate fibers by water bridging an optical tapered-coupler to a microlensed coupler. Our water fibers are held in air and their length can be longer than a millimeter. These hybrid fibers co-confine two important oscillations in nature: capillary- and electromagnetic-. We optically record vibrations in the water fiber, including an audio-rate fundamental and its 3 overtones in a harmonic series, that one can hear in soundtracks attached. Transforming Micro-Electro-Mechanical-Systems [MEMS] to Micro-Electro-Capillary-Systems [MECS], boosts the device softness by a million to accordingly improve its response to minute forces. Furthermore, MECS are compatible with water, which is a most important liquid in our world.

    In a previous research, a preliminary study was carried out on the disinfection efficiency of peracetic acid (PAA), comparing it to that of other disinfectants that are typically used, in batch tests with dosage values ranging from 0.5 to 5 ppm. The study was carried out on samples of water collected from several significant points of the treatment process at the main water treatment plant in Jesolo (Venice, Italy). On the basis of results (basically positive at that time) obtained from these tests, a 400 litre/hour pilot plant was built, as a lower scale reproduction of the drink water treatment system mentioned earlier, in order to study the characteristics of PAA even in tests that could more realistically simulate the flow of water along the process. These tests essentially confirmed the kinetics of the spontaneous hydrolysis to CH{sub 3} COOH+H{sub 2}O{sub 2} and those of dismutation to CH{sub 3}COOH+O{sub 2}, with half-life time values ranging from 3 to 12 hours, depending on the characteristics of the water (especially the pH factor) and the PAA concentration values.

    The major challenge for achieving a sustainable future for water resources and water security is the integration of water availability, water quality and water governance. Water is unevenly distributed on Planet Earth and these disparities are cause of several economic, ecological and social differences in the societies of many countries and regions. As a consequence of human misuse, growth of urbanization and soil degradation, water quality is deteriorating continuously. Key components for the maintenance of water quantity and water quality are the vegetation cover of watersheds, reduction of the demand and new water governance that includes integrated management, predictive evaluation of impacts, and ecosystem services. Future research needs are discussed.

  7. Water Conservation and Water Storage

    2014-12-01

    Water storage can be a viable part of the solution to water conservation. This means that we should include reservoirs. Regardless, one should evaluate all aspects of water conservation principles. Recent drought in California indicates that there is an urgent need to re-visit the techniques used to maintain the water supply-chain mechanism in the entire state. We all recognize the fact that fish and wildlife depend on the streams, rivers and wetlands for survival. It is a well-known fact that there is an immediate need to provide solid protection to all these resources. Laws and regulations should help meet the needs of natural systems. Farmers may be forced to drilling wells deeper than ever. But, they will be eventually depleting groundwater reserves. Needless to say that birds, fish and wildlife cannot access these groundwater table. California is talking a lot about conservation. Unfortunately, the conservation efforts have not established a strong visible hold. The Environmental Protection Agency has a plan called E2PLAN (Narayanan, 2012). It is EPA's plan for achieving energy and environmental performance, leadership, accountability, and carbon neutrality. In June 2011, the EPA published a comprehensive, multi-year planning document called Strategic Sustainability Performance Plan. The author has previously reported these in detail at the 2012 AGU fall meeting. References: Ziegler, Jay (15 JUNE 2014).

    Full Text Available Questo articolo presenta il rapporto tra Cesare Lombroso e la letteratura, con particolare riferimento alla prima edizione dell’Uomo delinquente (1876. Rispetto agli studi precedenti che hanno riguardato soprattutto l’“effetto lombroso“ sui critici e gli scrittori successivi, questo contributo presenta l’“effetto letteratura“ sul pensiero lombrosiano tra gli anni Sessanta e Settanta dell’Ottocento, quando Lombroso apprende dalla linguistica a riflettere sulle origini dell’uomo, dall’antropologia a definire la nozione di atavismo, dalla letteratura a modellare la propria scrittura narrativa. L’articolo cerca di precisare la struttura dell’Uomo delinquente, la retorica della descrizione fisiognomica (fondata sull’ipotiposi e non sull’iperbole e la biblioteca dei libri consigliati (in primis Dante e Manzoni, riletti con fortuna anche nella critica letteraria del tardo Ottocento italiano e proibiti (tra cui Ovidio, Petronio, Apuleio, la letteratura picaresca, il romanzo francese dell’Ottocento.

    Full Text Available Nell’ambito della discussione sulle potenzialità della lettura e dello studio letterario come strumento di alfabetizzazione nei diritti umani, il saggio intende proporre un’alternativa alle strategie di lettura proposte da Richard Rorty e Martha Nussbaum, le quali pongono l’accento sull’identificazione tra lettore e vittime. Prendendo a oggetto di analisi Un ricordo di Solferino, opera di Henry J. Dunant, il saggio esplora la possibilità di identificazione tra lettore e il volontario impegnato nella cura dei feriti e dei bisognosi, sostituendo all’empatia metaforica proposta da Rorty e Nussbaum un rapporto metonimico di contiguità. La sostituzione consente di superare la divisione lettore/vittima, che ripropone una relazione asimmetrica di potere tra l’Occidente e il resto del mondo, e avviare un discorso diretto a tutta l’umanità senza distinzione.

    The study is based on data collected for the area on a grid base (150x150 meters). For each cell of the grid, data on several parameters were collected (soil use, pesticide use, pedology, ground water depth, etc.). A data base with the chemical-physical parameter of 75 pesticides used in the area has been implemented. A ground flow model gives the number of days a pollutant takes to arrive at the lake from a given cell. A second model take into account the attenuation of pesticide load from the soil surface to the water table. Hazard maps are presented based on pesticide loads, attenuation factor, and ground flow to the lake water. The methodology has been implemented by integrating a Geographical Information System, data bases and simulation models. The work has been carried out in a project coordinated by Lazio Regional Agency for the Innovation and Development in Agriculture (ARSIAL) and supported by the Reg. CEE/2081/93 ob. 5b.

    Il volume raccoglie, oltre al testo della lezione del 1854 che dà il titolo all'opera, alcuni scritti di carattere scientifico e filosofico di Riemann. A saggi di argomento scientifico si affiancano scritti di argomento più direttamente metodologico. La concezione della scienza che ci viene offerta da questi scritti è assai significativa del personaggio e della sua epoca. Per Riemann la matematica non è un mero strumento esteriore da applicare, appunto dall'esterno, ai fenomeni. Al contrario, essa consente di spingersi con il rigore necessario oltre alla superficie dei fenomeni e di penetrare sempre più a fondo nella realtà, nell'ottica di un sistema unitario e quasi metafisico del sapere scientifico.

    Full Text Available Secondo Di Nuovo (2007, affinché la psicoterapia possa definirsi sperimentalmente convalidabile occorre che si avvalga, per la verifica delle proprie ipotesi, della triplice procedura adottata dalle scienze naturali, che ottenga cioè una convalida logica, una convalida pragmatica e una convalida esplicativa. La convalida logica pertiene alla coerenza tra teoria psicopatologica, obiettivi terapeutici e tecniche di intervento, e ha lo scopo di acquisire una concordanza tra le nuove conoscenze e il corpus teorico che né è matrice. La convalida pragmatica concorre alla verifica degli effetti: una strategia d’intervento è valutata secondo criteri di efficacia e di utilità. Questo approccio è definito in letteratura “outcome research” in quanto fondato sulla valutazione del risultato per mezzo di confronti pre e post-terapia ed eventuali follow up (Migone, 1996. La convalida esplicativa pertiene invece all’ambito della “process research” che considera il processo terapeutico nel suo incedere: è l’evolversi del cambiamento del paziente a essere posto a tema dell’indagine attraverso momenti di assessment periodici (Di Nuovo, 2007; Migone, 1996. Questo tipo di approccio è finalizzato a fornire il senso di ciò che accade in terapia definendo, al di là dell’esito, perché il trattamento funziona o meno. Il “cambiamento” può essere valutato secondo modalità essenzialmente quantitative, qualitative o attraverso una procedura mista. La valutazione quantitativa, sostanziando l’effetto esperienziale della terapia in misurazioni psicometriche, prescinde però perlopiù dal «Chi» del paziente (e del terapeuta; coglie il “quanto” ma non il “come” del processo terapeutico (Liccione, 2011; Liccione, 2012; Allegri et al., 2011; Petesi et al., 2011. L’alternativa qualitativa, invece, attraverso metodologie come l’analisi del discorso e l’analisi narrativa intende cogliere il senso del processo clinico, con specifico riferimento ai processi terapeutici che sottendono il cambiamento esperienziale del paziente (Di Nuovo, 2000. L’approccio ermeneutico fenomenologico, coniugando lo studio dell’autobiografia - nell’accezione ricoeuriana di identità narrativa - e lo studio dell’esperienza in prima persona, fornisce una possibile metodologia di analisi del processo terapeutico a contributo degli studi sulla process research.

    Full Text Available L’autore si interroga sul “senso complessivo” del lavoro di uno dei più importanti architetti della seconda metà del '900, tentando una lettura unitaria delle diverse fasi di cui si compone la sua opera: una prima fase tutta centrata sulla rivisitazione e lo sviluppo di canoni linguistici modernisti; una seconda di stampo “urbanistico”; quella successiva, della prima metà degli anni '90 più poetica, autenticamente creativa e immaginifica fino all'ultima tutta intrisa di religiosa spiritualità. / The author questions himself on the “overall sense” of the work of one of the most important architects of the second half of the 1900s, attempting a unified reading of the various phases that make up his work: a first phase all centred on a re-visitation and development of Modernist linguistic canons; a second of an “urbanistic” stamp; the successive one, from the first half of the 1990s that is more poetic, authentically creative and imaginative right up to the last one imbued with religious spirituality.

  4. Sulle orme di Racine e Metastasio: Il castigo di Atalia di David Franco-Mendes

    Directory of Open Access Journals (Sweden)

    Anna Linda Callow

    2011-06-01

    Full Text Available Atalia's Punishment by David Franco-Mendes is a biblical drama which belongs to the period of the  Hebrew Haskalah. The author declares openly that he was inspired by the works of Racine and Metastasio,  but although it is possible to identify many common features, there are also important differences. The character of Atalia is deprived of a tragic stature which could inspire sympathy in the reader,  while all the elements of the text regarding the Temple of Jerusalem and the coronation of the legitimate  heir to the lineage of David are amplified. In this way, the drama, as compared to the works of Racine  and Metastasio, is brought back to be closer to the sensibility of a Jewish audience. Its being written  according to the canons of modern literature, and in pure Biblical Hebrew, however, makes it ideally  accessible to an educated audience of non-Jewish origin. The work can then be interpreted as an attempt  to mediate between the Jewish and non-Jewish European culture, in the spirit of the Haskalah.

Séneca, Giovenale e Marziale parlano piú volte della croce. Séneca ne appare Impresslonato in modo speclale e Marziale cita il caso di uno schiavo crocifisso per avere Incendiato Roma.

    Full Text Available

    Introduzione: i continui flussi migratori in Puglia hanno posto una serie di problemi sul piano sanitario, inizialmente limitati alla gestione dell’emergenza ma subito estesi alla sorveglianza epidemiologica per la prevenzione di patologie infettive che possono essere importate da queste popolazioni. In tale ambito è stata condotta un’indagine anche sulla presenza di miceti che colonizzano il distretto otorinolaringoiatrico, con particolare riferimento ai funghi dimorfi, recentemente segnalati anche in Medio Oriente ma normalmente endemici in America e Africa.

    Metodi: l’indagine è stata condotta su un campione di 297 Kurdi, sbarcati ad Otranto (LE, maschi, età 15 - 35 anni (media 23 anni. Ciascun soggetto è stato sottoposto ad una visita otorinolaringoiatrica e al prelievo, mediante tampone sterile, del secreto orofaringeo, nasale e auricolare, per la ricerca di lieviti, muffe e funghi dimorfi.

    Risultati: dei 297 soggetti esaminati, 70 (23.6% sono risultati positivi per miceti (45 lieviti, 25 muffe di cui 36 (51.4% in sede nasale, 30 (42.9% in sede orofaringea e 4 (5.7% in sede auricolare. Tra i lieviti, Candida albicans è risultata la specie più frequente (66.7%, isolata esclusivamente a livello orofaringeo; tra le muffe Penicillium spp. (56% riscontrato solo a livello nasale. La ricerca di funghi dimorfi è risultata negativa.

    Conclusioni: la prevalente colonizzazione di muffe a livello nasale e di lieviti a livello orofaringeo conferma la sede di elezione da parte di questi microrganismi. Tuttavia, è interessante sottolineare che in sede nasale il genere Penicillium è risultato predominante rispetto al genere Aspergillus, contrariamente ai dati di letteratura. Inoltre, i funghi dimorfi non sono stati mai isolati anche se l’area geografica di provenienza è stata introdotta tra quelle endemiche per questi miceti. In conclusione, la nostra indagine evidenzia che l’incidenza delle positività per miceti non si discosta da quella tipica di popolazioni ad elevato livello socio sanitario, nonostante le avverse condizioni di viaggio.

    ABSTRACT: The study offers an analysis of the acts of violence taking place in Cologne during the new year’s Eve of 2015. The goal is to shed light on the likely or at least possible causes of what happened that night through a comparison with similar events that occurred elsewhere, in order to avoid interpreting those violent acts through religious motivations only. Within a larger and multidisciplinary study framework, it should be given relevance to the cultural, social and psychological forces that direct and shape the individual and group behavior.

    2016-03-01

    Full Text Available Lo scopo di questo paper è quello di sviluppare una lettura e un’interpretazione di uno degli scritti “minori” di Ludwig Wittgenstein, la Conferenza sull’Etica. La mia comprensione della Conferenza è inspirata principalmente dall’interpretazione della filosofia di Wittgenstein sviluppata da Pierre Hadot e, di conseguenza, la mia tesi consisterà nel dimostrare che seguendo Hadot la Conferenza sull’Etica può essere vista come un ‘Esercizio Spirituale’. Pertanto sostengo che la finalità principale di questo scritto va vista nel tentativo di cambiare la nostra attitudine verso il mondo, e dunque la nostra disposizione etica verso di esso. Ritengo inoltre che questo non sia solo lo scopo di ogni Esercizio Spirituale, bensì in generale quello dell’attività del filosofo austriaco, ossia, la volontà di coinvolgere i propri destinatari provocando in loro una riflessione e possibilmente un cambiamento in merito al proprio modo di vivere, e a tutta la sfera che va sotto il nome di “Etica”.

    Full Text Available La scienza medica segue da tempo un approccio evidence based grazie al quale è avanzata empiricamente per prove ed errori ottenendo innegabili risultati. Tale approccio ha incontrato grande fortuna in ambito medico ma non ancora in ambito educativo. Questa discrepanza viene spiegata sulla base della legge dell’effetto per cui, data una certa situazione, solo le risposte seguite da una ricompensa sono rafforzate e hanno buone probabilità di essere registrate come risposte abituali a quella situazione. L’approccio evidence based funziona bene quando applicato in ambito medico ma non (o perlomeno in misura molto minore in ambito educativo. In effetti, la pratica medica in tutto il suo processo dallo sviluppo delle conoscenze alla soddisfazione dei bisogni del paziente risponde alla legge dell’effetto. La stessa logica non pervade il processo della formazione e trasmissione del sapere educativo destinato a tradursi in proposte didattiche. Si auspica qualcosa cominci a cambiare.

    Full Text Available Negli ultimi anni il numero delle specie di Chirotteri note per l?Europa si è accresciuto, grazie all?uso di tecniche di genetica molecolare, ed in particolare il genere Plecotus è quello che ha registrato maggiori cambiamenti con la descrizione di tre nuove specie: Plecotus kolombatovici, P. alpinus e P. sardus (Kiefer & Veith, 2001; Mucedda et al., 2002. Alla luce di queste nuove scoperte, la distribuzione geografica e le preferenze dell?habitat delle due specie ?storiche? di Orecchione in Europa, Plecotus auritus e P. austriacus, dovrebbero essere riviste: in questo contesto si inserisce l?indagine svolta nel Parco Regionale Campo dei Fiori (in provincia di Varese sulla prima colonia riproduttiva di Plecotus alpinus segnalata per la regione Lombardia. Al fine di valutare le preferenze nell?uso dell?habitat e le direttrici di spostamento preferenziali di tale specie, nonché per l?identificazione di siti di rilevanza per l?allevamento della prole, si è fatto ricorso a tecniche di radiolocalizzazione, subordinate alla cattura a vivo degli animali. Le catture si sono svolte nel periodo 15 giugno ? 15 agosto del 2002 e del 2003. Per ogni individuo catturato, oltre alla determinazione di specie, sesso e classe d?età, sono stati rilevati i dati biometrici e prelevati campioni di tessuto destinati all?analisi genetica. Sono state inoltre registrate le emissioni ultrasonore. Durante il primo anno di indagine sono state seguite mediante radiolocalizzazione 5 femmine adulte (4 allattanti ed una non allattante e due femmine subadulte, mentre durante il secondo anno sono state munite di radiocollare 6 femmine adulte (5 allattanti ed una non allattante ed una femmina subadulta. Ai pipistrelli è stato applicato un emettitore radio (tag modello LB-2, Holohil Systems Ltd, Ontario, Canada. Il segnale emesso è stato ricevuto in campo mediante l?utilizzo di radio (Wildlife Materials, Inc. connesse ad antenne Yagi a tre elementi. Ogni animale è stato seguito a partire dall?uscita dal roost fino al definitivo rientro all?alba del giorno successivo, per tutto il periodo in cui il tag risultava attivo (7-10 giorni e ne è stata rilevata la posizione almeno ogni quindici minuti. I dati ottenuti sono stati integrati su Sistema Informativo Territoriale (GIS ARC/INFO 8.2 al fine di poter procedere all?elaborazione dei dati di localizzazione per l?analisi dei domini vitali e la definizione dei corridoi di spostamento e delle principali aree di foraggiamento. Dai dati ottenuti è risultato che la maggior parte degli individui indagati utilizza più di un sito di foraggiamento intorno al roost e nelle zone limitrofe del roost stesso, oltre a prati ed a una zona umida, presenti nelle immediate vicinanze e sfruttati non soltanto come sito di foraggiamento ma anche come punto di abbeverata. I domini vitali e le core area risultano del tutto confrontabili in termini di grandezza per la maggior parte degli animali radiomarcati; tuttavia, alcuni individui hanno effettuato spostamenti dell?ordine di 5-6 chilometri dal sito di rifugio. Per definire le caratteristiche ambientali delle zone maggiormente frequentate, è stato utilizzato l?indice di Ivlev, considerando la classificazione delle tipologie di copertura del suolo secondo la cartografia CORINE, livello III.

    Full Text Available The essay deals with Leopoldo Galeotti’s 1870 report about Florentine public schools, a report which so far has not been sufficiently studied by historians. It is useful to study the ambivalence of Tuscan post-Union moderates, divided between a discourse on the acculturation of the lower classes and a different anti-democratic practice. The essay also argues that in the second part of nineteenth-century liberalism was inspired by a view that differs from that of contemporary neoliberalism. While the paradigm of liberalism was based on “exchange”, the neo-liberal one builds upon competition.

    Obiettivo: valutare l’andamento epidemiologico della
    parotite in relazione alla variazione delle coperture vaccinali
    ed al tipo di vaccino utilizzato nell’Azienda U.S.L.
    N° 1 di Sassari nel periodo 1991-2001.

    Metodi: sono state analizzate tutte le notifiche di parotite
    dei tre Distretti di Sassari, Alghero e Ozieri nel periodo
    1991-2001 per risalire alla scheda vaccinale e conoscere
    il tipo di vaccino e la data di somministrazione.

    Risultati: sono stati notificati, nel periodo, 1000
    casi: 352 a Sassari, 510 ad Alghero e 138 ad Ozieri.
    In generale si è osservato nel periodo un livello di bassa endemia (26.4 per 105 con due rilievi epidemici in corrispondenza degli anni 1991-1995 ed un episodio francamente epidemico nel 2001 (193 per 105. L’epidemia del 2001 è iniziata l’anno precedente nel distretto di Alghero coinvolgendo successivamente Sassari e Ozieri. I maschi e le femmine risultano colpiti in eguale proporzione, la fascia
    più colpita è quella dei 5-9 anni senza differenze fra periodi epidemici e interepidemici.
    L’andamento stagionale è tipico con picco a fine inverno, inizio primavera. Le coperture sono risultate costantemente superiori all’80% fino al 1995 quando, grazie ad un offerta attiva dell’Azienda, si sono potuti raggiungere valori prossimi al 90%; la successiva offerta gratuita a partire dal 1997 ha consentito di superare questa soglia. Nel 6% dei
    casi non era noto lo stato vaccinale, mentre il 55.3% risultavano regolarmente vaccinati, con tassi d’attacco di 19,.% tra i vaccinati e del 20.7% tra i non vaccinati (efficacia=4.3%. Nel complesso il 53.1% era stato vaccinato con il ceppo Rubini ed il 36.6% con quello Urabe AM9.

    Conclusioni: i risultati confermano la scarsa efficacia
    dei ceppi utilizzati. Pertanto è stata avviata una
    campagna di vaccinazione antiparotitica con ceppo
    RIT 4385 secondo la strategia di recupero alle età di
    5 e 12 anni e delle occasioni opportune. In tale ottica
    si auspica una sempre più forte sinergia tra
    Servizi vaccinali e Pediatri di libera scelta per rendere
    condivisa questa strategia e per effettuare una
    corretta e capillare informazione delle famiglie.

The suffering that he endured, dealt with the perception of dramas animating the history of the colonized world of the early 20th century, as well as the discontent experienced in the USSR’s satellite States. This perception seems to become real and definite thanks to his cosmic and mystic conception of human beings, in spite of the accusation and declaration of “materialism” against the poet and claimed by the author himself.

    Full Text Available Attraverso l’analisi di alcune teorie filosofiche islamiche medievali, l’articolo intende indagare la tipologia di approccio che autori come Avicenna e Averroè adottarono nei confronti di religioni diverse da quelle di origine (ebraismo, cristianesimo, zoroastrismo e sabeismo ed elaborare una riflessione sul concetto di universalità nella religione islamica. Analizzerò le loro dottrine sull’insegnamento profetico, tenendo presenti le fonti platoniche da cui esse si svilupparono, e illustrerò i motivi per cui esse occuparono un posto fondamentale nella scienza politica e le finalità di queste teorie. Attraverso il confronto con diversi studiosi, che nei loro articoli hanno prestato attenzione alla domanda sulla naturalità o sulla positività della Legge islamica, cercherò di andare all’origine della questione, indagando quale fosse il messaggio universale che essi rintracciarono nella Legge rivelata e il motivo che li indusse a presentarlo come rivolto all’intero genere umano.

    2015-07-01

    Full Text Available Is it any use to compare two nations such as Spain and Italy? Why not extend it to other nations? Or, conversely, why not dwell on one of the two cases by analyzing it in depth? These three simple questions require a careful reflection on the logic of comparison in the social sciences. In the construction of a research design, the comparatist must in fact solve some methodological tangles by establishing: 1 the «unit (or units of analysis» on which the research should be oriented; 2 The space-temporal context in which the research ranks; 3 the conceptual definition of properties (or variables. These three operations have some methodological implications which require an effort of conceptualization and classification necessary for a proper comparative research. In addition, researchers must make a clear strategic choice with respect to their empirical path. After determining the research field, it is necessary to cope with the problem of choosing the most appropriate units to be selected as a sample. The choice to compare two countries similar in many respects and historically connected such as Spain and Italy assumes the use of the so-called strategy of “most similar systems design”. It is useful to solve the problem of the “diffusion” and to reduce the unwanted historical associations. Starting from these reflections, the aim of this paper is to analyze the methodological implications of the comparison between the two countries under study.

    Francia, F

    2014-01-01

    Many preventive services do not apply EBP interventions, but continue to employ resources in activities clearly ineffective. This happens even though there is full knowledge of the futility of certain practices. It follows a fall of responsiveness in the relationship with the user, which does not understand the misalignment between what we do and what should be done. It is therefore necessary to realign the work plans to the real problems of health, not just the provision of the law passed by the times. To achieve this goal hygienists must be more leaders and innovators than manager oriented to the achievement of merely quantitative production targets. In this scenario should be paid great attention to the cultural change of operators who must not have a behavior not consonant to the new way of working.

  18. Analyzing rare diseases terms in biomedical terminologies Analizzare la terminologia biomedica sulle malattie rare

    2012-06-01

    Full Text Available Rare disease patients too often face common problems, including the lack of access to correct diagnosis, lack of quality information on the disease, lack of scientific knowledge of the disease, inequities and difficulties in access to treatment and care. These things could be changed by implementing a comprehensive approach to rare diseases, increasing international cooperation in scientific research, by gaining and sharing scientific knowledge about and by developing tools for extracting and sharing knowledge. A significant aspect to analyze is the organization of knowledge in the biomedical field for the proper management and recovery of health information. For these purposes, the sources needed have been acquired from the Office of Rare Diseases Research, the National Organization of Rare Disorders and Orphanet, organizations that provide information to patients and physicians and facilitate the exchange of information among different actors involved in this field. The present paper shows the representation of rare diseases terms in biomedical terminologies such as MeSH, ICD-10, SNOMED CT and OMIM, leveraging the fact that these terminologies are integrated in the UMLS. At the first level, it was analyzed the overlap among sources and at a second level, the presence of rare diseases terms in target sources included in UMLS, working at the term and concept level. We found that MeSH has the best representation of rare diseases terms.Pazienti affetti da malattie rare molto spesso affrontano problemi comuni, tra cui la mancanza di accesso alla diagnosi corretta, la mancanza di informazioni di qualità sulla malattia, la mancanza di conoscenze scientifiche, e le difficoltà di accesso al trattamento e cura. Inadempienze e lacune che potrebbero essere colmate mediante l'attuazione di un approccio globale alle malattie rare, aumentando la cooperazione internazionale nella ricerca scientifica e lo sviluppo di strumenti per l'estrazione e la condivisione delle conoscenze. Il saggio analizza l’uso dei termini riguardanti le malattie rare in terminologie biomediche come MeSH, ICD-10, SNOMED CT e OMIM, sfruttando il fatto che queste terminologie sono integrate negli UMLS. Al primo livello, è stata analizzata la sovrapposizione tra le fonti e, ad un secondo livello, la presenza di termini riguardanti malattie rare nelle fonti target incluse nella UMLS. A tal fine, MeSH risulta avere la migliore rappresentazione di termini riguardanti le malattie rare.

    Full Text Available The purpose of this article is to examine Merleau-Ponty’s early analysis on animality, particularly referring to his first work The Structure of Behaviour. The article focuses on the review of notions like “behaviour” and “gestalt” and on the analysis of the tripartition of the forms of animal behaviour. It will be underlined both the richness and the ambiguity of Merleau-Ponty’s first reflection. Indeed on the one hand, the French philosopher immediately discovers an ontological continuity between animals and humans but, on the other hand, his point of view on animality is still “privative”.

  20. Storia del pensiero statistico con alcune osservazioni sull'insegnamento della statistica

    Directory of Open Access Journals (Sweden)

    Rodolfo de Cristofaro

    2007-10-01

    Full Text Available Statistical thinking changed in a striking way since its birth. From the descriptive statistics, linked up the research of statistical regularity, until the investigative statistics in the first part of XX century. Successively, the change was much quicker. First of all, statisticians put sampling and inference as the central core of the matter. Fisher came up with a revolutionary idea to solve the problem of inductive reasoning, by preliminarily designing the experiments in the process of data generation. However, Fisher's inference was no longer probabilistic, involving conclusions and choices which are outside the scope of probability theory. Then, Neyman substituted inductive behavior for Fisher's inductive reasoning, who he considered as a basic concept of philosophy of science. Later on, Neyman's ideas were further developed by Wald, who, in turn, transformed statistics in decision theory. Finally, Savage logically supported the Bayesian paradigm, prominent in all Statistics. Recently, statisticians promoted some pedagogical reasons to hesitate in introducing Bayesian paradigm to beginners. In particular, they placed variability (or "variation" as the essential mark in statistical teaching and in empirical enquiry, linked up a revaluation of the causal research and even of the old investigative statistics. The present paper compares the development of statistical thinking with respect to the similar change in philosophy of science from Galileo and Bacon until nowadays. Besides, it suggests coming back in placing phenomena considered from a non-deterministic viewpoint (collective phenomena as the study subject of the matter, with a revaluation of all phases of statistical method, from the initial definition of a phenomenon until the final decision. Likewise, the essential mark in statistical teaching should be the method of scientific research rather than the pure and simple study of variation.

    Full Text Available Most of the water treatment plant, filtration is done by means of sand filtration process. Due to continuous filtration process, sand pores get clogged and decreases the efficiency. For mitigating such problem, reverse flow of water & air i.e. backwashing process is carried out. To carry out backwashing operation, 4% of treated water has been utilized and will result in muddy water known as backwash water. This backwash water is then discharged into a natural stream or storage tank near the plant for recirculation. The present study includes a trial for the reuse & recirculation of backwash water.

    Full Text Available L'evoluzione della produzione libraria sull'Islam e sul Mondo arabo-islamico in Italia dopo l'11 Settembre 2001 presenta degli interessanti spunti di valutazione per quanto riguarda lo stretto rapporto fra Oriente e l'immagine che il lettore ha dell'Oriente. Dallo studio in questione emerge come, le aree geoeditoriali di approvvigionamento, le lingue dalle quali sono tradotti i testi, le principali case editrici e gli autori più prolifici siano orientati in gran parte verso una ben precisa direzione culturale. Le evidenze statistiche dimostrano come il rapporto fra il nostro Occidente e quel particolare Oriente che è l'Islam, presenta ancora degli evidenti punti oscuri. L'aumento quasi incontrollato del numero di titoli e del numero di autori sembra non aver portato alla nascita di una consapevolezza differente nel lettore. Scarseggiano le iniziative programmate nel tempo e le colanne con una vita e una ragion d'essere ben precisa. L'improvvisazione e gli istant book rappresentano dei casi piuttosto frequenti. L'assunzione di figure giornalistiche a veri e propri cultori della materia, combinata con i giochi di potere della distribuzione, disegna infine l'ultima tendenza, che svuota le università e le accademie di gran parte del proprio diritto a divulgare, per donare al lettore una visione dell'Oriente creata quasi dal nulla dall'intellettuale di turno.  

  3. Improved water does not mean safe water

    Science.gov (United States)

    MacDonald, L. H.; Guo, Y.; Schwab, K. J.

    2012-12-01

    This work presents a model for estimating global access to drinking water that meets World Health Organization (WHO) water quality guidelines. The currently accepted international estimate of global access to safe water, the WHO and United Nations Children's Fund's (UNICEF) Joint Monitoring Program (JMP) report, estimates the population with access to water service infrastructure that is classified as improved and unimproved. The JMP report uses access to improved water sources as a proxy for access to safe water, but improved water sources do not always meet drinking water quality guidelines. Therefore, this report likely overestimates the number of people with access to safe water. Based on the JMP estimate, the United Nations has recently announced that the world has reached the Millennium Development Goal (MDG) target for access to safe water. Our new framework employs a statistical model that incorporates source water quality, water supply interruptions, water storage practices, and point of use water treatment to estimate access to safe water, resulting in a figure that is lower than the JMP estimate of global access to safe water. We estimate that at least 28% of the world does not have access to safe water today, as compared to the JMP estimate of 12%. These findings indicate that much more work is needed on the international scale to meet the MDG target for access to safe water.

    2009-06-01

    Full Text Available Based on fieldwork in four different spas —two in Spain and two in Portugal— this paper shows the mutiple social mediations operating in water therapies in different contexts: from the local use inscribed in popular knowledge, including playful elements inserted in therapeutic practices under the illusion of a return to nature when nature itself has stopped being «natural», to others in which leisure time is an expression of an exclusive life style including a reevaluation of landscape as part of a time-bound aesthetics and as a refuge from urban stress. These different uses of water allow us to understand spas both as nature sanatoriums as well as a form of business where medical power bends to the interests of turistic enterpreneurs transformed into health advisors, linked to different conceptions not only of water but also of society itself.

    Focalizando la reflexión en cuatro balnearios diferentes —dos en España y dos en Portugal—, el artículo muestra las múltiples mediaciones sociales que operan en la terapéutica del agua en diferentes contextos: desde el uso local inserto en saberes populares, incluyendo lo lúdico en lo terapéutico que puede conectarse con la ilusión de un regreso a la naturaleza cuando ésta ya ha dejado de ser “natural”, a otros en los que el ocio es expresión de un estilo de vida exclusivo que incluye un acercamiento al paisaje como parte de la estética de una época y como refugio ante el stress urbano. Se observa así cómo estos usos del agua, que permiten concebir los balnearios bien como sanatorios de la naturaleza bien como negocios en los que el poder médico se pliega al de promotores turísticos convertidos en asesores de salud, se vinculan a concepciones diferentes no sólo del agua, sino de la sociedad misma y sus diferentes grupos.

    2011-07-01

    Full Text Available Nel contesto di analisi delle condizioni di lavoro nell’era della conoscenza e delle tecnologie digitali, il nostro contributo vuole mettere l’attenzione sulle rappresentazioni dei/lle knowledge workers sulla progressiva ridefinizione dell’esperienza corporea, in direzione della perdita di rapporto con il corpo concreto, a favore di un corpo astrattamente inteso. Il discorso si colloca nella logica del “capitalismo tecno-nichilista”, inteso come “un sistema che, sfruttando la sistematica separazione tra le funzioni e i significati, si è progressivamente affermato quale modello di riferimento nel corso degli ultimi decenni”. La domanda di ricerca che ci poniamo in questo contributo è: in qual modo la precarizzazione del lavoro modifica le percezioni dei soggetti, e nello specifico dei lavoratori e delle lavoratrici della conoscenza, nella relazione con il proprio corpo? Nel discutere tale questione, intendiamo concentrarci non solo sugli effetti, ma anche sui processi e sulle relazioni sociali in cui i soggetti – e in varie forme anche le loro esperienze corporee – sono coinvolte.

  13. Virtual water trade and world water resources.

    Science.gov (United States)

    Oki, T; Kanae, S

    2004-01-01

    Global virtual water trade was quantitatively estimated and evaluated. The basic idea of how to estimate unit requirement of water resources to produce each commodity is introduced and values for major agricultural and stock products are presented. The concept of virtual water and the quantitative estimates can help in assessing a more realistic water scarcity index in each country, projecting future water demand for food supply, increasing public awareness on water, and identifying the processes wasting water in the production. Really required water in exporting countries is generally smaller than virtually required water in importing countries, reflecting the comparative advantage of water use efficiency, and it is estimated to be 680 km3/y for 2000. On the contrary the virtually required water for the same year is estimated to be 1,130 km3/y, and the difference of 450 km3/y is virtually saved by global trade. However, solely virtual water should not be used for any decision making since the idea of virtual water implies only the usage and influence of water and no concerns on social, cultural, and environmental implications. Virtual water trade also does not consider other limiting factors than water.

    Heviánková, Silvie; Marschalko, Marian; Chromíková, Jitka; Kyncl, Miroslav; Korabík, Michal

    2016-10-01

    With regard to the adverse manifestations of the recent climatic conditions, Europe as well as the world have been facing the problem of dry periods that reduce the possibility of drawing drinking water from the underground sources. The paper aims to describe artificial ground water recharge (infiltration) that may be used to restock underground sources with surface water from natural streams. Among many conditions, it aims to specify the boundary and operational conditions of the individual aspects of the artificial ground water recharge technology. The principle of artificial infiltration lies in the design of a technical system, by means of which it is possible to conduct surplus water from one place (in this case a natural stream) into another place (an infiltration basin in this case). This way, the water begins to infiltrate into the underground resources of drinking water, while the mixed water composition corresponds to the water parameters required for drinking water.

    Asano, T

    2005-01-01

    Increasing urbanization has resulted in an uneven distribution of population, industries, and water in urban areas; thus, imposing unprecedented pressures on water supplies and water pollution control. These pressures are exacerbated during the periods of drought and climatic uncertainties. The purpose of this paper is to summarize emergence of water reclamation, recycling and reuse as a vital component of sustainable water resources in the context of integrated water resources management in urban and rural areas. Water quality requirements and health and public acceptance issues related to water reuse are also discussed. Reclaimed water is a locally controllable water resource that exists right at the doorstep of the urban environment, where water is needed the most and priced the highest. Closing the water cycle loop not only is technically feasible in agriculture, industries, and municipalities but also makes economic sense. Society no longer has the luxury of using water only once.

    2016-07-01

    The rapid development resulted in the deterioration of the quality of drinking water in Malaysia. Recognizing the importance of water quality, new alternatives for drinking water such as mineral water processing from reverse osmosis (RO) machine become more popular. Hence, the demand for mineral water, natural spring water or water from the hills or mountains rose lately. More consumers believed the quality of these spring water better than other source of drinking water. However, the quality of all the drinking water sources is to meet the required quality standard. Therefore, this paper aims to measure the quality of the waters from hills, from RO machine and the water supply in Ulu Yam, Selangor Batang Kali, Malaysia. The water quality was determined based on following parameters: ammoniacal nitrogen (NH3), iron (Fe), turbidity (NTU) and pH. The results show that the water from hills has better quality compared to water supply and water from RO machine. The value of NH3 ranged from 0.03 mg/L- 0.67 mg/L; Fe was from 0.03mg/L - 0.12 mg/L, turbidity at 0.42 NTU - 0.88 NTU and pH is at 6.60 - 0.71. Based on the studied parameters, all three types of water are fit for drinking and have met the required national drinking water quality standard.

    Water covers more than two thirds of the surface of the Earth and about the same fraction of water forms the total mass of a human body. Since the early days of our civilization water has also been in the focus of technological developments, starting from converting it to wine to more modern achievements. The meeting will focus on recent advances in experimental, theoretical, and computational understanding of the behavior of the most important and fascinating liquid in a variety of situations and applications. The emphasis will be less on water properties per se than on water as a medium in which fundamental dynamic and reactive processes take place. In the following sessions, speakers will discuss the latest breakthroughs in unraveling these processes at the molecular level: Water in Solutions; Water in Motion I and II; Water in Biology I and II; Water in the Environment I and II; Water in Confined Geometries and Water in Discussion (keynote lecture and poster winners presentations).

    Suncor's oil sands operations produce 225,000 bbl/day of crude oil products from Alberta's Fort McMurray area. Water is a key resource used for enhanced recovery methods to produce crude oil products from oil sands. A water management strategy is required to monitor and control the amount of water used in the bitumen liberation process, cooling, the steam assisted gravity drainage process, steam for cogeneration, an energy transfer medium, a transportation medium, feedstock, and potable water. The water management strategy is designed to manage both short and long term water issues and develop sustainable water management strategies in an integrated manner. The strategy also encourages open communication on water to optimize synergy between operators, energy producers, and governments. The opportunities and challenges of a water management strategy were outlined with reference to recycling opportunities, managing water chemistry, and improving the ability to measure water use.

    In Europe (e.g., in Italy), and in the States, the opinion is widely spreading that the negative consequences of modern progress are the fault of "Science". A lively debate on this topic took place among the famous writer Leonardo Sciascia and Italian physicists like Edoardo Amaldi and Emilio Segre', when Sciascia wrote his known book about the disappearance of Ettore Majorana, a book that presented Majorana (a very reserved theoretical physicist) as an example of the scientist that keeps his discoveries secret when afraid of possible evil applications. We wish to contribute now to such a question, since many special meetings did recently return to it, while celebrating the centenary of Majorana's birth (2006), or 30 years (2005) from Sciascia's book publication. It appeared natural to us to start with the figure of Einstein, who, even if extremely peaceable, supported the atomic bomb construction by his letter to Roosvelt. We discuss first the significance of part of Einsteins's scientific work (which flouri...

  9. Beethoven rilegge il proprio passato: alcune riflessioni sul rapporto tra le ultime due Sonate e l'Op. 10 n. 1

    Directory of Open Access Journals (Sweden)

    Piero Venturini

    2014-01-01

    Full Text Available Questo lavoro ha due tipi di finalità: la prima riguarda piuttosto la riflessione teorica mentre la seconda è basata sulla pratica esecutiva quotidiana. Dal punto di vista teorico-poietico c’è un’osservazione di partenza solo apparentemente banale. Mentre esiste un’enorme quantità di materiale, sia nella letteratura analitica sia in quella musicologica, che documenta gli influssi di compositori del passato e coevi  sull’opera di Beethoven – mi limito a ricordare qui solo i testi di Webster [1995] e Dahlhaus [1990] – non è altrettanto ben documentata l’influenza che il Beethoven giovanile ha nei confronti del compositore maturo. In cosa le ultime opere del genio di Bonn sono debitrici nei confronti delle opere della gioventù? Più genericamente ci si potrebbe anche chiedere quale sia il movente che spinge un compositore a rileggere le proprie opere del passato e con quale chiave di lettura esse vengano reinterpretate. Dal punto di vista pratico-estesico questo lavoro è partito da un’intuizione estremamente personale e soggettiva: lo studio dell’op. 110 e 111 ha provocato un collegamento spontaneo e irrazionale con l’op 10 n. 1; in pratica, dopo lo studio al pianoforte delle ultime due sonate di Beethoven, lo scrivente si è più volte trovato a canticchiare alcune parti dell’op. 10 n. 1. Visto che il fatto si è ripetuto praticamente dopo ogni seduta di studio, è nata  l’esigenza di una ricerca sui rapporti tra le opere in oggetto. Ovviamente la prima cosa è stata chiarire se questi collegamenti avessero un fondamento oggettivo o non si trattasse piuttosto di una forma di vissuto musicale individuale legata ad impressioni  soggettive. Le strade battute per evitare il rischio di soggettività sono state due: l’esame della letteratura sull’argomento e l’ancoraggio ad una solida metodologia analitica.

    The research was carried out at the Monte Sinni mine, a sub-bituminous coal mine located in the south west of Sardinia (Italy). The aim of the research has been to develop a control system for materials flow and for the traffic of the tyred vehicles designed specifically for coal mines. In particular, it has been tried to simulate control of each materials supply step starting from the surface stores to the working sites and vice-versa. The hardware has been supplied by Montan-Forschung (Germany) and the software has been produced by Tele Data Software in Cagliari (Italy). Instrumentation is made up by two physically separated parts. The first has been designed to control the run of the trolley truck and allows the exchange of both data and voice between the driver and a main receiving station. The second controls the run of each transport unit by means of data bearing tags (TPD) which are provided with a fixed numerical identification code and are attached to the units. The transport cycle is controlled by the operating software installed on a personal computer that operates as a `main station`. The control-system of the materials flow has given satisfactory results that have allowed the research to achieve its aims. The future application of the system in the mine will bring about certain advantages also by an economic point of view, mostly due to reduction of the materials supply times, as well as the impossibility of shunting mistakes and miscarriages of the load or part of it.

Animated by the search of the connection between the sensitive-emotional sphere and the linguistics one, he wants to build a “physiology” of language. Moreover, his investigation of the properties and function of language leads to questions about the domain of aesthetic and spiritual experience. Through its symbolic power and guided by self-consciousness, then the word can express everything that moves and excites man by the form.

    World's population numbered 6.1 billion in 2000 and is currently increasing at a rate of about 77 million per year. By 2025, the estimated total world population will be of the order of 7.9 billion. Water plays a central role in any systematic appraisal of life sustaining requirements. Water also strongly influences economic activity (both production and consumption) and social roles. Fresh water is distributed unevenly, with nearly 500 million people suffering water stress or serious water scarcity. Two-thirds of the world's population may be subjected to moderate to high water stress in 2025. It is estimated that by 2025, the total water use will increase by to 40%. The resources of water supply and recreation may also come under stress due to changes in climate such as water balance for Lake Balaton (Hungary). Conventional urban water systems such as water supply, wastewater, and storm water management are also currently going through stress and require major rethinking. To maintain urban water systems efficiently in the future, a flexibility approach will allow incorporation of new technologies and adaptation to external changes (for example society or climate change). Because water is an essential resource for sustaining health, both the quantity and quality of available water supplies must be improved. The impact of water quality on human health is severe, with millions of deaths each year from water-borne diseases, while water pollution and aquatic ecosystem destruction continue to rise. Additionally, emerging contaminants such as endocrine disruptor chemicals (EDCs), pharmaceuticals, and toxins in the water body are also of a great concern. An innovative ferrate(VI) technology is highly effective in removing these contaminants in water. This technology is green, which addresses problems associated with chlorination and ozonation for treating pollutants present in water and wastewater. Examples are presented to demonstrate the applications of ferrate

  14. Water Footprints and Sustainable Water Allocation

    Directory of Open Access Journals (Sweden)

    Arjen Y. Hoekstra

    2015-12-01

    Full Text Available Water Footprint Assessment (WFA is a quickly growing research field. This Special Issue contains a selection of papers advancing the field or showing innovative applications. The first seven papers are geographic WFA studies, from an urban to a continental scale; the next five papers have a global scope; the final five papers focus on water sustainability from the business point of view. The collection of papers shows that the historical picture of a town relying on its hinterland for its supply of water and food is no longer true: the water footprint of urban consumers is global. It has become clear that wise water governance is no longer the exclusive domain of government, even though water is and will remain a public resource with government in a primary role. With most water being used for producing our food and other consumer goods, and with product supply chains becoming increasingly complex and global, there is a growing awareness that consumers, companies and investors also have a key role. The interest in sustainable water use grows quickly, in both civil society and business communities, but the poor state of transparency of companies regarding their direct and indirect water use implies that there is still a long way to go before we can expect that companies effectively contribute to making water footprints more sustainable at a relevant scale.

    Water is used in almost all human endeavour. Unlike oil, water does not have a substitute. There are many factors that affect the water consumption pattern of people. These include climatic condition, income level and agricultural practices among others. The water footprint concept has been developed in order to have an indicator of water use in relation to its consumption by people. The water footprint of a country is defined as the volume of water needed for the production of the goods and services consumed by the inhabitants of the country (Chapagain and Hoekstra, 2008). Due to the bulky nature of water, it is not in its raw state a tradable commodity though it could be traded through the exchange of goods and services from one point to the other. Closely linked to the water footprint concept is the virtual water concept. Virtual water can be defined as the volume of water required to produce a commodity or service (Chapagain and Hoekstra, 2008 and Allan, 1999). The international trade of these commodities implies flows of virtual water over large distances. The water footprint of a nation can therefore be assessed by quantifying the use of domestic water resources, taking out the virtual water flow that leaves the country and adding the virtual water flow that enters the country to it. This research focuses on the assessment and analysis of the water footprints of Ghana considering only the consumptive component of the water footprint. In addition to livestock, 13 crops were considered, 4 of which were cash crops. Data was analysed for the year 2001 to 2005 The most recent framework for the analysis of water footprint is offered by Chapagain and Hoekstra. This was adopted for the study. The water footprint calculations show that the water footprint of Ghana is about 20011 Gm³/yr. Base on this the average water footprint of a Ghanaian is 823 m³/cap/yr. Not only agricultural crops but also other products require water for their manufacture, aluminium being a

  8. The global water cycle

    Science.gov (United States)

    Oki, Taikan; Entekhabi, Dara; Harrold, Timothy Ives

    The global water cycle consists of the oceans, water in the atmosphere, and water in the landscape. The cycle is closed by the fluxes between these reservoirs. Although the amounts of water in the atmosphere and river channels are relatively small, the fluxes are high, and this water plays a critical role in society, which is dependent on water as a renewable resource. On a global scale, the meridional component of river runoff is shown to be about 10% of the corresponding atmospheric and oceanic meridional fluxes. Artificial storages and water withdrawals for irrigation have significant impacts on river runoff and hence on the overall global water cycle. Fully coupled atmosphere-land-river-ocean models of the world's climate are essential to assess the future water resources and scarcities in relation to climate change. An assessment of future water scarcity suggests that water shortages will worsen, with a very significant increase in water stress in Africa. The impact of population growth on water stress is shown to be higher than that of climate change. The virtual water trade, which should be taken into account when discussing the global water cycle and water scarcity, is also considered. The movement of virtual water from North America, Oceania, and Europe to the Middle East, North West Africa, and East Asia represents significant global savings of water. The anticipated world water crisis widens the opportunities for the study of the global water cycle to contribute to the development of sustainability within society and to the solution of practical social problems.

    Any and all chemicals generated by human activity can and will find their way into water supplies. The types and quantities of carcinogens present in drinking water at the point of consumption will differ depending on whether they result from contamination of the source water, arise as a consequence of treatment processes, or enter as the water is conveyed to the user. Source-water contaminants of concern include arsenic, asbestos, radon, agricultural chemicals, and hazardous waste. Of these,...

    California's water rights system allocates water based on priority, where lower priority, "junior" rights are curtailed first in a drought. The Drought Water Rights Allocation Tool (DWRAT) was developed to integrate water right allocation models with legal objectives to suggest water rights curtailments during drought. DWRAT incorporates water right use and priorities with a flow-forecasting model to mathematically represent water law and hydrology and suggest water allocations among water rights holders. DWRAT is compiled within an Excel workbook, with an interface and an open-source solver. By implementing California water rights law as an algorithm, DWRAT provides a precise and transparent framework for the complicated and often controversial technical aspects of curtailing water rights use during drought. DWRAT models have been developed for use in the Eel, Russian, and Sacramento river basins. In this study, an initial DWRAT model has been developed for the San Joaquin watershed, which incorporates all water rights holders in the basin and reference gage flows for major tributaries. The San Joaquin DWRAT can assess water allocation reliability by determining probability of rights holders' curtailment for a range of hydrologic conditions. Forecasted flow values can be input to the model to provide decision makers with the ability to make curtailment and water supply strategy decisions. Environmental flow allocations will be further integrated into the model to protect and improve ecosystem water reliability.

    The parameters influencing the extraction efficiency of total water-soluble Zn, Pb and Cd in various soil samples from a lead and zinc mining area were investigated. Water was added to moist soil sample and the mixture shaken in a classical shaker. Variations of the solution volume to soil weight ratio, and of extraction time were studied in order to develop an optimum extraction procedure for determination of total water-soluble Zn, Pb and Cd. The influence of filtration of the extracts through membrane filters of various pore size was investigated as well. Speciation of Zn, Pb and Cd was also performed in aqueous soil extracts using column chelating ion-exchange (Chelex-100 resin) - flame atomic absorption spectrometry (FAAS) technique. Positively charged species and labile complexes of Zn, Pb and Cd were retained on the column and after elution with nitric acid determined by FAAS. Comparative analyses of the total metal concentrations in the soil samples indicated that the percentage of total water soluble Zn, Pb and Cd in samples analyses in these extracts by the chelating ion-exchange - FAAS technique demonstrated that Zn, Pb and Cd exist in the form of positively charged species or weak labile metal complexes. [Italian] Si sono studiati i parametri che influenzano l'efficienza di estrazione delle forme completamente solubili di Zn, Pb e Cd in vari campioni di terreno provenienti da un'area mineraria di piombo e zinco.

Si sono studiate le variazioni del rapporto tra volume di soluzione e peso del terreno e del tempo di estrazione per sviluppare una procedura ottimizzata di estrazione per la determinazione delle frazioni totalmente solubili in acuqa di Zn, Pb e Cd. Si e' pure studiata l'influenza della filtrazione degli estratti attraverso membrane di diversa porosita'. Si e' poi effettuata la speciazione di Zn, Pb e Cd

    Water is essential to life, but many people do not have access to clean and safe drinking water and many die of waterborne bacterial infections. In this review a general characterization of the most important bacterial diseases transmitted through water-cholera, typhoid fever and bacillary dysentery-is presented, focusing on the biology and ecology of the causal agents and on the diseases' characteristics and their life cycles in the environment. The importance of pathogenic Escherichia coli strains and emerging pathogens in drinking water-transmitted diseases is also briefly discussed. Microbiological water analysis is mainly based on the concept of fecal indicator bacteria. The main bacteria present in human and animal feces (focusing on their behavior in their hosts and in the environment) and the most important fecal indicator bacteria are presented and discussed (focusing on the advantages and limitations of their use as markers). Important sources of bacterial fecal pollution of environmental waters are also briefly indicated. In the last topic it is discussed which indicators of fecal pollution should be used in current drinking water microbiological analysis. It was concluded that safe drinking water for all is one of the major challenges of the 21st century and that microbiological control of drinking water should be the norm everywhere. Routine basic microbiological analysis of drinking water should be carried out by assaying the presence of Escherichia coli by culture methods. Whenever financial resources are available, fecal coliform determinations should be complemented with the quantification of enterococci. More studies are needed in order to check if ammonia is reliable for a preliminary screening for emergency fecal pollution outbreaks. Financial resources should be devoted to a better understanding of the ecology and behavior of human and animal fecal bacteria in environmental waters.

    1997-03-01

    Water has been taken for granted as an essential public health need since the Victorian sanitary revolution. Water has come back on to the public health agenda in the United Kingdom because of recent policy changes and their untoward environmental and social impacts; along with water privatization and tough new environmental directives, there have been serious water pollution incidents, water shortages, water debt and disconnection. Along with concern about protecting individual rights to a clean safe water supply, there is concern about the ability of national water resources to meet all our communities' needs, without unacceptable environmental damage. A national plan is needed for the conservation of water and protection of water resources and the environment; adequate central funds are needed to see that this happens. There should be greater emphasis on local water management and a key role for local authorities; there should be fair pricing, protection of water supplies for the poorest and most vulnerable, and a ban on water disconnection to domestic users, on public health grounds. More research is needed into the potential adverse health impact of people on prepayment meters disconnecting themselves. There is a place for water metering as the most rapidly deliverable means of controlling peak demand, reducing overall consumption and avoiding a large-scale environmentally damaging solution to supply more water. However, control of leakage offers the largest potential saving and is the most cost-effective means to protect existing water supply. We question whether private water companies, geared to maximizing profit and share dividends, can deliver a national plan for the protection and management of water resources, for the good of the environment and future generations. The public health lobby must become more actively engaged in the debate about the supply, protection and price of our most precious public health asset-water.

    2010-07-01

    This special issue is devoted to illustrating important aspects and significant results in the field of modeling and simulation of water at interfaces with solutes or with confining substrates, focusing on a range of temperatures from ambient to supercooled. Understanding the behavior of water, in contact with different substrates and/or in solutions, is of pivotal importance for a wide range of applications in physics, chemistry and biochemistry. Simulations of confined and/or interfacial water are also relevant for testing how different its behavior is with respect to bulk water. Simulations and modeling in this field are of particular importance when studying supercooled regions where water shows anomalous properties. These considerations motivated the organization of a workshop at CECAM in the summer of 2009 which aimed to bring together scientists working with computer simulations on the properties of water in various environments with different methodologies. In this special issue, we collected a variety of interesting contributions from some of the speakers of the workshop. We have roughly classified the contributions into four groups. The papers of the first group address the properties of interfacial and confined water upon supercooling in an effort to understand the relation with anomalous behavior of supercooled bulk water. The second group deals with the specific problem of solvation. The next group deals with water in different environments by considering problems of great importance in technological and biological applications. Finally, the last group deals with quantum mechanical calculations related to the role of water in chemical processes. The first group of papers is introduced by the general paper of Stanley et al. The authors discuss recent progress in understanding the anomalies of water in bulk, nanoconfined, and biological environments. They present evidence that liquid water may display 'polymorphism', a property that can be present in

    Urban water systems consist of large-scale technical systems and both natural and man-made water bodies. The technical systems are essential components of urban infrastructure for water collection, treatment, storage and distribution, as well as for wastewater and runoff collection and subsequent treatment. Urban aquatic ecosystems are typically subject to strong human influences, which impair the quality of surface and ground waters, often with far-reaching impacts on downstream aquatic ecosystems and water users. The various surface and subsurface water bodies in urban environments can be viewed as interconnected compartments that are also extensively intertwined with a range of technical compartments of the urban water system. As a result, urban water systems are characterized by fluxes of water, solutes, gases and energy between contrasting compartments of a technical, natural or hybrid nature. Referred to as urban water interfaces, boundaries between and within these compartments are often specific to urban water systems. Urban water interfaces are generally characterized by steep physical and biogeochemical gradients, which promote high reaction rates. We hypothesize that they act as key sites of processes and fluxes with notable effects on overall system behaviour. By their very nature, urban water interfaces are heterogeneous and dynamic. Therefore, they increase spatial heterogeneity in urban areas and are also expected to contribute notably to the temporal dynamics of urban water systems, which often involve non-linear interactions and feedback mechanisms. Processes at and fluxes across urban water interfaces are complex and less well understood than within well-defined, homogeneous compartments, requiring both empirical investigations and new modelling approaches at both the process and system level. We advocate an integrative conceptual framework of the urban water system that considers interfaces as a key component to improve our fundamental

    2010-04-01

    Transport through lipids and aquaporins is osmotic and entirely driven by the difference in osmotic pressure. Water transport in cotransporters and uniporters is different: Water can be cotransported, energized by coupling to the substrate flux by a mechanism closely associated with protein. In the K(+)/Cl(-) and the Na(+)/K(+)/2Cl(-) cotransporters, water is entirely cotransported, while water transport in glucose uniporters and Na(+)-coupled transporters of nutrients and neurotransmitters takes place by both osmosis and cotransport. The molecular mechanism behind cotransport of water is not clear. It is associated with the substrate movements in aqueous pathways within the protein; a conventional unstirred layer mechanism can be ruled out, due to high rates of diffusion in the cytoplasm. The physiological roles of the various modes of water transport are reviewed in relation to epithelial transport. Epithelial water transport is energized by the movements of ions, but how the coupling takes place is uncertain. All epithelia can transport water uphill against an osmotic gradient, which is hard to explain by simple osmosis. Furthermore, genetic removal of aquaporins has not given support to osmosis as the exclusive mode of transport. Water cotransport can explain the coupling between ion and water transport, a major fraction of transepithelial water transport and uphill water transport. Aquaporins enhance water transport by utilizing osmotic gradients and cause the osmolarity of the transportate to approach isotonicity.

  11. Low water FGD technologies

    Energy Technology Data Exchange (ETDEWEB)

    2012-11-15

    Conventional flue gas desulphurisation (FGD) systems require large supplies of water. Technologies which reduce water usage are becoming more important with the large number of FGD systems being installed in response to ever tightening emission regulations. Reducing water loss is particularly important in arid regions of the world. This report reviews commercial and near commercial low water FGD processes for coal-fired power plants, including dry, semi-dry and multi-pollutant technologies. Wet scrubbers, the most widely deployed FGD technology, account for around 10–15% of the water losses in power plants with water cooling systems. This figure is considerably higher when dry/air cooling systems are employed. The evaporative water losses can be reduced by some 40–50% when the flue gas is cooled before it enters the wet scrubber, a common practice in Europe and Japan. Technologies are under development to capture over 20% of the water in the flue gas exiting the wet scrubber, enabling the power plant to become a water supplier instead of a consumer. The semi-dry spray dry scrubbers and circulating dry scrubbers consume some 60% less water than conventional wet scrubbers. The commercial dry sorbent injection processes have the lowest water consumption, consuming no water, or a minimal amount if the sorbent needs hydrating or the flue gas is humidified to improve performance. Commercial multi-pollutant systems are available that consume no water.

    Science.gov (United States)

    Katz, V L

    1996-08-01

    Exercise in the water offers several physiological advantages to the pregnant woman. The hydrostatic force of water pushes extravascular fluid into the vascular spaces, producing an increase in central blood volume that may lead to increased uterine blood flow. This force is proportional to the depth of immersion. The increase in blood volume is proportional to the woman's edema. A marked diuresis and natriuresis accompanies the fluid shifts. The buoyancy of water supports the pregnant women. Water is thermoregulating. Studies of pregnant women exercising in the water have shown less fetal heart rate changes in the water than on land in response to exertion. Pregnant women's heart rates and blood pressures during water exercise are lower than on land exercise, reflecting the immersion-induced increase in circulating blood volume. The physiology of water exercise offers some compensation for the physiological changes of exercise on land that may beneficially affect pregnancy.

    Water is an essential element in the future of cities. It shapes cities’ locations, form, ecology, prosperity and health. The changing nature of urbanisation, climate change, water scarcity, environmental values, globalisation and social justice mean that the models of provision of water services and infrastructure that have dominated for the past two centuries are increasingly infeasible. Conventional arrangements for understanding and managing water in cities are being subverted by a range of natural, technological, political, economic and social changes. The prognosis for water in cities remains unclear, and multiple visions and discourses are emerging to fill the space left by the certainty of nineteenth century urban water planning and engineering. This book documents a sample of those different trajectories, in terms of water transformations, option, services and politics.

    The buildup of scale and corrosion is the most costly maintenance problem in cooling tower operation. Jet Propulsion Laboratory successfully developed a non-chemical system that not only curbed scale and corrosion, but also offered advantages in water conservation, cost savings and the elimination of toxic chemical discharge. In the system, ozone is produced by an on-site generator and introduced to the cooling tower water. Organic impurities are oxidized, and the dissolved ozone removes bacteria and scale. National Water Management, a NASA licensee, has installed its ozone advantage systems at some 200 cooling towers. Customers have saved money and eliminated chemical storage and discharge.

    A water budget is an accounting of water movement into and out of, and storage change within, some control volume. Universal and adaptable are adjectives that reflect key features of water-budget methods for estimating recharge. The universal concept of mass conservation of water implies that water-budget methods are applicable over any space and time scales (Healy et al., 2007). The water budget of a soil column in a laboratory can be studied at scales of millimeters and seconds. A water-budget equation is also an integral component of atmospheric general circulation models used to predict global climates over periods of decades or more. Water-budget equations can be easily customized by adding or removing terms to accurately portray the peculiarities of any hydrologic system. The equations are generally not bound by assumptions on mechanisms by which water moves into, through, and out of the control volume of interest. So water-budget methods can be used to estimate both diffuse and focused recharge, and recharge estimates are unaffected by phenomena such as preferential flow paths within the unsaturated zone. Water-budget methods represent the largest class of techniques for estimating recharge. Most hydrologic models are derived from a water-budget equation and can therefore be classified as water-budget models. It is not feasible to address all water-budget methods in a single chapter. This chapter is limited to discussion of the “residual” water-budget approach, whereby all variables in a water-budget equation, except for recharge, are independently measured or estimated and recharge is set equal to the residual. This chapter is closely linked with Chapter 3, on modeling methods, because the equations presented here form the basis of many models and because models are often used to estimate individual components in water-budget studies. Water budgets for streams and other surface-water bodies are addressed in Chapter 4. The use of soil-water budgets and

    The United States uses huge quantities of water. In 1976, for example, it was estimated that for each person in the U.S., about 2,000 gallons of water were used daily in homes, offices, farms, and factories. This means that roughly 420 billion gallons of water were pumped, piped, or diverted each day—about 15 percent more than in 1970. By the year 2000, our daily water needs will probably exceed 800 billion gallons.

    With increasing population pressure and water usage coupled with climate variability and change, water issues are being reported by numerous groups as the most critical environmental problems facing us in the 21st century. Competitive uses and the prevalence of river basins and aquifers that extend across boundaries engender political tensions between communities, stakeholders and countries. In addition to the numerous water availability issues, water quality related problems are seriously affecting human health and our environment. The potential crises and conflicts especially arise when water is competed among multiple uses. For example, urban areas, environmental and recreational uses, agriculture, and energy production compete for scarce resources, not only in the Western U.S. but throughout much of the U.S. and also in numerous parts of the world. Mitigating these conflicts and meeting water demands and needs requires using existing water resources more efficiently. The NASA Water Resources Program Element works to use NASA products and technology to address these critical water issues. The primary goal of the Water Resources is to facilitate application of NASA Earth science products as a routine use in integrated water resources management for the sustainable use of water. This also includes the extreme events of drought and floods and the adaptation to the impacts from climate change. NASA satellite and Earth system observations of water and related data provide a huge volume of valuable data in both near-real-time and extended back nearly 50 years about the Earth's land surface conditions such as precipitation, snow, soil moisture, water levels, land cover type, vegetation type, and health.

    Although it recognizes the tangible economic benefits to health and income that may derive from greater safety of supply and improved time savings in procurement, planning for improvements of urban water systems in developing countries has overlooked other ways in which water may influence health and income among the poor. In these populations the price of water may further affect health and labor productivity, both directly through its impact on nutrition and indirectly through its impact on housing size and quality and on residential density. What at first might seem a straightforward equity issue in planning may thus be an issue of economic efficiency as well. Failure to account for the fuller range of tangible benefits associated with improvements in water supply may lead to underestimation of returns to investment and therefore to economically inefficient investment.

    Water footprints and virtual water flows have been promoted as important indicators to characterize human-induced water consumption. However, environmental impacts associated with water consumption are largely neglected in these analyses. Incorporating water scarcity into water consumption allows better understanding of what is causing water scarcity and which regions are suffering from it. In this study, we incorporate water scarcity and ecosystem impacts into multiregional input-output analysis to assess virtual water flows and associated impacts among 30 provinces in China. China, in particular its water-scarce regions, are facing a serious water crisis driven by rapid economic growth. Our findings show that inter-regional flows of virtual water reveal additional insights when water scarcity is taken into account. Consumption in highly developed coastal provinces is largely relying on water resources in the water-scarce northern provinces, such as Xinjiang, Hebei, and Inner Mongolia, thus significantly contributing to the water scarcity in these regions. In addition, many highly developed but water scarce regions, such as Shanghai, Beijing, and Tianjin, are already large importers of net virtual water at the expense of water resource depletion in other water scarce provinces. Thus, increasingly importing water-intensive goods from other water-scarce regions may just shift the pressure to other regions, but the overall water problems may still remain. Using the water footprint as a policy tool to alleviate water shortage may only work when water scarcity is taken into account and virtual water flows from water-poor regions are identified.

If he still looks a little unsatisfied, you would explain that our bodies are three-fourths water, and that water covers threefourths of the earth's surface. But you would have to admit to yourself that these facts, interesting as they are, do not quite answer the boy's question: "What is water?"

    In Danchira village in Ghana for the last 5 years, women and children rise before dawn every day to fetch water from a tributary or the River Densu, which is 5 miles from the village. Diminished rainfall has dried the village's 3 ponds and bore-hole where the women and children used to fetch water. To exacerbate the water problem, the Ghana Water and Sewerage Corporation no longer comes to fill the huge water tank it brought to Danchira when water scarcity first occurred. The villagers could not afford to pay for the water. A 55-year-old mother of 5, Dede Aryehteye, takes her morning bath at the river. When she has dirty laundry, she cleans it in the river. She returns to the village around 8 am. She uses the next hour to filter the dark water 2 times with a device provided free of charge by the national Guinea Worm Eradication Programme to keep the larvae out of the water. Next she sort the water for 3 uses: drinking, household use, and evening bath. Dede then does other domestic chores. She would rather go to her cassava farm in the early morning when it is cool but has to fetch water instead. When she is not too tired and after finishing domestic chores, she goes to the farm. Water-fetching also exhausts the children and gets them to school rather late. Children make up the majority of the 500 people living in Danchira. Water scarcity forced most of the young villagers to flee to the cities. For example, Dede's 4 older children now live in Accra. The water scarcity keeps the farmers from growing maize, cassava, and vegetables.

    Drinking water quality is the great public health concern because it is a major risk factor for high incidence of diarrheal diseases in Nepal. In the recent years, the prevalence rate of diarrhoea has been found the highest in Myagdi district. This study was carried out to assess the quality of drinking water from different natural sources, reservoirs and collection taps at Arthunge VDC of Myagdi district. A cross-sectional study was carried out using random sampling method in Arthunge VDC of Myagdi district from January to June,2010. 84 water samples representing natural sources, reservoirs and collection taps from the study area were collected. The physico-chemical and microbiological analysis was performed following standards technique set by APHA 1998 and statistical analysis was carried out using SPSS 11.5. The result was also compared with national and WHO guidelines. Out of 84 water samples (from natural source, reservoirs and tap water) analyzed, drinking water quality parameters (except arsenic and total coliform) of all water samples was found to be within the WHO standards and national standards.15.48% of water samples showed pH (13) higher than the WHO permissible guideline values. Similarly, 85.71% of water samples showed higher Arsenic value (72) than WHO value. Further, the statistical analysis showed no significant difference (Pwater for collection taps water samples of winter (January, 2010) and summer (June, 2010). The microbiological examination of water samples revealed the presence of total coliform in 86.90% of water samples. The results obtained from physico-chemical analysis of water samples were within national standard and WHO standards except arsenic. The study also found the coliform contamination to be the key problem with drinking water.

    One of the first requisites for the intelligent planning of utilization and control of water and for the administration of laws relating to its use is data on the quantity, quality, and mode of occurrence of the available supplies. The collection, evaluation and interpretation, and publication of such data are among the primary functions of the U.S. Geological Survey. Since 1895 the Congress has made appropriations to the Survey for investigation of the water resources of the Nation. In 1929 the Congress adopted the policy of dollar-for-dollar cooperation with the States and local governmental agencies in water-resources investigations of the U.S. Geological Survey. In 1937 a program of ground-water investigations was started in cooperation with the Oklahoma Geological Survey, and in 1949 this program was expanded to include cooperation with the Oklahoma Planning and Resources Board. In 1957 the State Legislature created the Oklahoma Water Resources Board as the principal State water agency and it became the principal local cooperator. The Ground Water Branch of the U.S. Geological Survey collects, analyzes, and evaluates basic information on ground-water resources and prepares interpretive reports based on those data. Cooperative ground-water work was first concentrated in the Panhandle counties. During World War II most work was related to problems of water supply for defense requirements. Since 1945 detailed investigations of ground-water availability have been made in 11 areas, chiefly in the western and central parts of the State. In addition, water levels in more than 300 wells are measured periodically, principally in the western half of the State. In Oklahoma current studies are directed toward determining the source, occurrence, and availability of ground water and toward estimating the quantity of water and rate of replenishment to specific areas and water-bearing formations. Ground water plays an important role in the economy of the State. It is

    Full Text Available Australia is the driest inhabited continent on earth and, more importantly, experiences the most variable rainfall of all the continents on our planet. The vast majority of Australians live in large cities on the coast. Because wastewater treatments plants were all located near the coast, it was thought that large scale recycling would be problematic given the cost of infrastructure and pumping required to establish recycled water schemes. This all changed when Australia experienced a decade of record low rainfall and water utilities were given aggressive targets to increase the volume of water recycled. This resulted in recycled water being accepted as a legitimate source of water for non-drinking purposes in a diversified portfolio of water sources to mitigate climate risk. To ensure community support for recycled water, Australia lead the world in developing national guidelines for the various uses of recycled water to ensure the protection of public health and the environment. Australia now provides a great case study of the developments in maximizing water recycling opportunities from policy, regulatory and technological perspectives. This paper explores the evolution in thinking and how approaches to wastewater reuse has changed over the past 40 years from an effluent disposal issue to one of recognizing wastewater as a legitimate and valuable resource. Despite recycled water being a popular choice and being broadly embraced, the concept of indirect potable reuse schemes have lacked community and political support across Australia to date.

    Full Text Available Freshwater scarcity has increased at an alarming rate worldwide; improved water management plays a vital role in increasing food production and security. This study aims to determine the water footprint of Brazil’s national food consumption, the virtual water flows associated with international trade in the main agricultural commodities, as well as water scarcity, water self-sufficiency and water dependency per Brazilian region. While previous country studies on water footprints and virtual water trade focused on virtual water importers or water-scarce countries, this is the first study to concentrate on a water-abundant virtual water-exporting country. Besides, it is the first study establishing international virtual water trade balances per state, which is relevant given the fact that water scarcity varies across states within the country, so the origin of virtual water exports matters. The results show that the average water footprint of Brazilian food consumption is 1619 m3/person/year. Beef contributes most (21% to this total. We find a net virtual water export of 54.8 billion m3/year, mainly to Europe, which imports 41% of the gross amount of the virtual water exported from Brazil. The northeast, the region with the highest water scarcity, has a net import of virtual water. The southeast, next in terms of water scarcity, shows large virtual water exports, mainly related to the export of sugar. The north, which has the most water, does not show a high virtual water export rate.

Current statistics on human water use are often outdated or inaccurately reported nationally, especially for groundwater. This study improves these estimates by defining human water use in two ways. First, we use NASA's Gravity Recovery and Climate Experiment (GRACE) to isolate the anthropogenic signal in water storage anomalies, which we equate to water use. Second, we quantify an ideal water demand by using average water requirements for the domestic, industrial, and agricultural water use sectors. Water availability has traditionally been limited to "renewable" water, which ignores large, stored water sources that humans use. We compare water stress estimates derived using either renewable water or the total volume of water globally. We use the best-available data to quantify total aquifer and surface water volumes, as compared to groundwater recharge and surface water runoff from land-surface models. The work presented here should provide a more realistic image of water stress by explicitly quantifying groundwater, defining water availability as total water supply, and using GRACE to more accurately quantify water use.

    Gleick, Peter H.

    In “Challenging the Rhetoric of Water Wars” (Eos, In Brief, September 5, 2000, p. 410) Randy Showstack reported on the speech given by Minister Kader Asmal upon receiving the 2000 Stockholm Water Prize. This prize was well deserved for the tremendous progress South Africa has made under Minister Asmal's leadership in addressing basic water needs after apartheid. Indeed, I was one of his nominators for this prize and am an ardent fan of his bold programs. But his remarks about water-related conflicts need to be qualified. In his speech, Minister Asmal noted that water scarcity is a “crisis of biblical proportion,” but also suggested “there is not a shred of evidence” to back up arguments that there are water “wars.”

    2007-07-24

    Methods for removing arsenic from water by addition of inexpensive and commonly available magnesium oxide, magnesium hydroxide, calcium oxide, or calcium hydroxide to the water. The hydroxide has a strong chemical affinity for arsenic and rapidly adsorbs arsenic, even in the presence of carbonate in the water. Simple and commercially available mechanical methods for removal of magnesium hydroxide particles with adsorbed arsenic from drinking water can be used, including filtration, dissolved air flotation, vortex separation, or centrifugal separation. A method for continuous removal of arsenic from water is provided. Also provided is a method for concentrating arsenic in a water sample to facilitate quantification of arsenic, by means of magnesium or calcium hydroxide adsorption.

    Water arrives in the mammalian gestation from the maternal circulation across the placenta. It then circulates between the fetal water compartments, including the fetal body compartments, the placenta and the amniotic fluid. Amniotic fluid is created by the flow of fluid from the fetal lung and bladder. A major pathway for amniotic fluid resorption is fetal swallowing; however in many cases the amounts of fluid produced and absorbed do not balance. A second resorption pathway, the intramembranous pathway (across the amnion to the fetal circulation), has been proposed to explain the maintenance of normal amniotic fluid volume. Amniotic fluid volume is thus a function both of the amount of water transferred to the gestation across the placental membrane, and the flux of water across the amnion. Membrane water flux is a function of the water permeability of the membrane; available data suggests that the amnion is the structure limiting intramembranous water flow. In the placenta, the syncytiotrophoblast is likely to be responsible for limiting water flow across the placenta. In human tissues, placental trophoblast membrane permeability increases with gestational age, suggesting a mechanism for the increased water flow necessary in late gestation. Membrane water flow can be driven by both hydrostatic and osmotic forces. Changes in both osmotic/oncotic and hydrostatic forces in the placenta my alter maternal-fetal water flow. A normal amniotic fluid volume is critical for normal fetal growth and development. The study of amniotic fluid volume regulation may yield important insights into the mechanisms used by the fetus to maintain water homeostasis. Knowledge of these mechanisms may allow novel treatments for amniotic fluid volume abnormalities with resultant improvement in clinical outcome.

    As a general rule drinking water in hospitals does not represent a risk for the normal patient. However, for high-risk patients with compromised immune defense systems drinking water in hospitals may become a source of nosocomial infections. It may be contaminated with microorganisms that may have the potential to be infectious agents in the hospital environment. Of particular significance in such circumstances are the Gram-negative rods such as Pseudomonas aeruginosa, Acinetobacter spp. and Legionella bacteria. Accordingly, specific behavior patterns and measures in the handling of drinking water in hospitals are meaningful in order to reduce the risks of water-associated nosocomial infections.

    Energy Technology Data Exchange (ETDEWEB)

    Conio, O. [Azienda Mediterranea Gas e Acqua spa, Genua (Italy)

    1998-12-31

    By involving institutions and rules, and technology as well, water resources management presents remarkable complexity. In institutions such a complexity is due to division of competence into monitoring activities, quality control, water utility supply and water treatment. As far as technology goes, complexity results from a wide range of physical, chemical and biological requisites, which define water quality according to specific water uses (for populations, farms, factories). Thus it`s necessary to have reliable and in-time environmental data, so to fulfil two complementary functions: 1) the control of any state of emergency, such as floods and accidental pollution, in order to take immediate measures by means of timely available information; 2) the mid- and long-term planning of water resources, so to achieve their reclamation, conservation and exploitation. An efficient and reliable way to attain these goals is to develop integrated continuous monitoring systems, which allow to control the quality of surface and underground water, the flow of bodies of water and those weather conditions that directly affect it. Such systems compose an environmental information network, which enables to collect and process data relative to the state of the body of water, its aquifer, and the weather conditions.

  17. Jumping on water

    Science.gov (United States)

    Kim, Ho-Young

    2016-11-01

    Water striders can jump on water as high as they can jump on land. Quick jumps allow them to avoid sudden dangers such as predators' attacks, and therefore understanding how they make such a dramatic motion for survival can shed light on the ultimate level of semi-aquatic motility achievable through evolution. However, the mechanism of their vertical jumping from a water surface has eluded hydrodynamic explanations so far. By observing movements of water strider legs and theoretically analyzing their dynamic interactions with deforming liquid-air interface, we have recently found that different species of jumping striders always tune their leg rotation speed with a force just below that required to break the water surface to reach the maximum take-off velocity. Here, we start with discussing the fundamental theories of dynamics of floating and sinking of small objects. The theories then enable us to analyze forces acting on a water strider while it presses down the water surface to fully exploit the capillary force. We further introduce a 68-milligram at-scale robotic insect capable of jumping on water without splash, strikingly similar to the real strider, by utilizing the water surface just as a trampoline.

    We have chosen to present the topic "Water", by illustrating problems that will give better opportunities for interdisciplinary work between Natural Science (Physics, Chemistry, Biology and Geology) teachers at first, but also English teachers and maybe others. Water is considered in general, in all its shapes and states. The question is not only about drinking water, but we would like to demonstrate that water can both be a fragile and short-lived resource in some ways, and an unlimited energy resource in others. Water exists on Earth in three states. It participates in a large number of chemical and physical processes (dissolution, dilution, biogeochemical cycles, repartition of heat in the oceans and the atmosphere, etc.), helping to maintain the homeostasis of the entire planet. It is linked to living beings, for which water is the major compound. The living beings essentially organized themselves into or around water, and this fact is also valid for human kind (energy, drinking, trade…). Water can also be a destroying agent for living beings (tsunamis, mud flows, collapse of electrical dams, pollution...) and for the solid earth (erosion, dissolution, fusion). I) Water, an essential resource for the human kind After having highlighted the disparities and geopolitical problems, the pupils will study the chemistry of water with its components and their origins (isotopes, water trip). Then the ways to make it drinkable will be presented (filtration, decantation, iceberg carrying…) II) From the origin of water... We could manage an activity where different groups put several hypotheses to the test, with the goal to understand the origin(s?) of water on Earth. Example: Isotopic signature of water showing its extraterrestrial origin.. Once done, we'll try to determine the origin of drinking water, as a fossil resource. Another use of isotopes will allow them to evaluate the drinking water age, to realize how precious it can be. III) Water as a sustainable energy

    2010-05-01

    In a context where water resources are unevenly distributed and, in some regions precipitation and drought conditions are increasing, enhanced water management is a major challenge to final consumers, businesses, water resource users, water managers and policymakers in general. By linking a large range of sectors and issues, virtual water trade and water footprint analyses provide an appropriate framework to find potential solutions and contribute to a better management of water resources. The water footprint is an indicator of freshwater use that looks not only at direct water use of a consumer or producer, but also at the indirect water use. The water footprint of a product is the volume of freshwater used to produce the product, measured over the full supply chain. It is a multi-dimensional indicator, showing water consumption volumes by source and polluted volumes by type of pollution; all components of a total water footprint are specified geographically and temporally. The water footprint breaks down into three components: the blue (volume of freshwater evaporated from surface or groundwater systems), green (water volume evaporated from rainwater stored in the soil as soil moisture) and grey water footprint (the volume of polluted water associated with the production of goods and services). Closely linked to the concept of water footprint is that of virtual water trade, which represents the amount of water embedded in traded products. Many nations save domestic water resources by importing water-intensive products and exporting commodities that are less water intensive. National water saving through the import of a product can imply saving water at a global level if the flow is from sites with high to sites with low water productivity. Virtual water trade between nations and even continents could thus be used as an instrument to improve global water use efficiency and to achieve water security in water-poor regions of the world.

The water quality module is equipped to handle constituent reactions within the bulk pipe flow and at the pipe wall. It also features an efficient computational scheme that automatically determines optimal time steps and pipe segmentation for accurate tracking of material transport over time. EPANET is currently being used in the US to study such issues as loss of chlorine residual, source blending and trihalomethane (THM) formation, how altered tank operation affects water age, and total dissolved solids (TDS) control for an irrigation network.

  6. Managing water for life

    Institute of Scientific and Technical Information of China (English)

    2012-01-01

    Water is essential for life. In spite of the entire engineering infrastructure devoted to the treatment, regulation and beneficial uses of water, occasionally sufficient quantities and qualities of water become scarce. When this happens, just how do we decide how much less water to allocate to all of us and the activities we engage in to sustain and enhance our quality of life? This paper addresses some of the complexities of answering such a question, especially as society increasingly recognizes the need to provide flow regimes that will maintain healthy aquatic and floodplain ecosystems that also impact the economic, physical and even the spiritual quality of our lives. For we depend on these ecosystems to sustain our wellbeing. We are indeed a part of our ecosystems. We depend upon on aquatic ecosystems to moderate river flow qualities and quantities, reduce the extremes of floods and droughts, reduce erosion, detoxify and decompose water- borne wastes, generate and preserve flood plain soils and renew their fertility, regulate disease carrying organisms, and to enhance recreational benefits of river systems. This question of deciding just how much water to allocate to each water user and for the maintenance of viable aquatic ecosystems, especially when there is not enough, is a complex, and largely political, issue. This issue is likely to become even more complex and political and contentious in the future as populations grow and as water quantities and their qualities become even more variable and uncertain.

  12. Purge water management system

    Cardoso-Neto, Joao E.; Williams, Daniel W.

    1996-01-01

    A purge water management system for effectively eliminating the production of purge water when obtaining a groundwater sample from a monitoring well. In its preferred embodiment, the purge water management system comprises an expandable container, a transportation system, and a return system. The purge water management system is connected to a wellhead sampling configuration, typically permanently installed at the well site. A pump, positioned with the monitoring well, pumps groundwater through the transportation system into the expandable container, which expands in direct proportion with volume of groundwater introduced, usually three or four well volumes, yet prevents the groundwater from coming into contact with the oxygen in the air. After this quantity of groundwater has been removed from the well, a sample is taken from a sampling port, after which the groundwater in the expandable container can be returned to the monitoring well through the return system. The purge water management system prevents the purge water from coming in contact with the outside environment, especially oxygen, which might cause the constituents of the groundwater to oxidize. Therefore, by introducing the purge water back into the monitoring well, the necessity of dealing with the purge water as a hazardous waste under the Resource Conservation and Recovery Act is eliminated.

    2012-12-01

    Water scarcity, and its implications for human and ecosystem wellbeing, is well documented. To mitigate activities that exacerbate water scarcity, and to adapt to scarcity when it is unavoidable, we must understand the drivers of water scarcity. Based on data from the new WaterGAP3 model, we analyze patterns of water stress and water use in watersheds globally. Our data include information on multi-sectoral water withdrawal and consumption as well as irrigation data for individual crops. We assess monthly water use and availability as well as annual trends. Of 11,050 basins, about 2.5% are over-extended, with higher levels of water consumption than available water. In most of these basins, irrigated agriculture dominates water withdrawals. In the majority of basins (92%), less than 20% of available water is consumed by human activity. This leaves just 5.5% of basins potentially stressed; they may not be experiencing water limitation at present, but they are highly susceptible. We consider both water availability (supply) and water withdrawals and consumption (demand) as drivers of water stress, finding that over-extended basins are both dry, with about one fifth of the water availability of the lowest stress basins, and heavy water consumers, with more than double the water consumption of moderate-stress basins. Identifying basins likely to experience water stress, and strategies and characteristics of those that are not, will help put all basins on a path toward water sustainability.

    2003-03-01

    The Idaho National Engineering and Environmental Laboratory (INEEL) covers approximately 890 mi2 and includes 12 public water systems that must be evaluated for Source water protection purposes under the Safe Drinking Water Act. Because of its size and location, six watersheds and five aquifers could potentially affect the INEEL’s drinking water sources. Based on a preliminary evaluation of the available information, it was determined that the Big Lost River, Birch Creek, and Little Lost River Watersheds and the eastern Snake River Plain Aquifer needed to be assessed. These watersheds were delineated using the United States Geologic Survey’s Hydrological Unit scheme. Well capture zones were originally estimated using the RESSQC module of the Environmental Protection Agency’s Well Head Protection Area model, and the initial modeling assumptions and results were checked by running several scenarios using Modflow modeling. After a technical review, the resulting capture zones were expanded to account for the uncertainties associated with changing groundwater flow directions, a thick vadose zone, and other data uncertainties. Finally, all well capture zones at a given facility were merged to a single wellhead protection area at each facility. A contaminant source inventory was conducted, and the results were integrated with the well capture zones, watershed and aquifer information, and facility information using geographic information system technology to complete the INEEL’s Source Water Assessment. Of the INEEL’s 12 public water systems, three systems rated as low susceptibility (EBR-I, Main Gate, and Gun Range), and the remainder rated as moderate susceptibility. No INEEL public water system rated as high susceptibility. We are using this information to develop a source water management plan from which we will subsequently implement an INEEL-wide source water management program. The results are a very robust set of wellhead protection areas that will

    2003-01-01

    Surface water in Hawaii is a valued resource as well as a potential threat to human lives and property. The surface-water resources of Hawaii are of significant economic, ecologic, cultural, and aesthetic importance. Streams supply more than 50 percent of the irrigation water in Hawaii, and although streams supply only a few percent of the drinking water statewide, surface water is the main source of drinking water in some places. Streams also are a source of hydroelectric power, provide important riparian and instream habitats for many unique native species, support traditional and customary Hawaiian gathering rights and the practice of taro cultivation, and possess valued aesthetic qualities. Streams affect the physical, chemical, and aesthetic quality of receiving waters, such as estuaries, bays, and nearshore waters, which are critical to the tourism-based economy of the islands. Streams in Hawaii pose a danger because of their flashy nature; a stream's stage, or water level, can rise several feet in less than an hour during periods of intense rainfall. Streams in Hawaii are flashy because rainfall is intense, drainage basins are small, basins and streams are steep, and channel storage is limited. Streamflow generated during periods of heavy rainfall has led to loss of property and human lives in Hawaii. Most Hawaiian streams originate in the mountainous interiors of the islands and terminate at the coast. Streams are significant sculptors of the Hawaiian landscape because of the erosive power of the water they convey. In geologically young areas, such as much of the southern part of the island of Hawaii, well-defined stream channels have not developed because the permeability of the surface rocks generally is so high that rainfall infiltrates before flowing for significant distances on the surface. In geologically older areas that have received significant rainfall, streams and mass wasting have carved out large valleys.

    Producing goods and services all needs water consumption. The water used in the process of an agricultural or industrial product is called the "Virtual Water" contained in this product.Through international trade, water-scarce countries and regions could purchase water-intensive products--especially foods, from water-rich countries to balance their water deficits and achieve water safety. China is one of the 13 most water-deficit countries whose water safety have been severely challenged. This paper generalized the recent global research development and made a brief introduction about the methods calculating virtual water content in specific products. As a case study, we qualified China's annual virtual water flows from year 2000 to 2002 with trade in crops, and ended with some policy advice for application and practice of virtual water strategy.

    New regulations on emission from waste incineration are under consideration of European Union. Besides hazardous waste - which is already the object of a 1994 directive - the new regulations will apply to all kinds of incinerated waste, with a net advantage of about 5000 milliard liras. As far as Italy is concerned, there shouldn't be a great change as regulations on the matter are, for many aspects, more advanced that those of other European countries. A specific regulation will deal with co-incineration, that is with waste used as fuel in plants producing electric energy. [Italian] L'Unione Europea ha allo studio una nuova normativa per disciplinare le emissioni legate all'incineramento dei rifiuti. Ad essere regolati saranno non solo quelli pericolosi, gia' oggetto di una direttiva del 1994, ma tutti i rifiuti smaltiti attraverso l'incenerimento. Le nuove regole dovrebbero portare un vantaggio netto di circa 5000 miliardi di lire. Per l'Italia non dovrebbe cambiare molto visto che la normativa in materia e' per molti aspetti piu' avanzata di quella di altri stati europei. Una disciplina a parte viene prevista per il coincenerimento, vale a dire per i rifiuti utilizzati come combustibile, sia nei cementifici che negli impianti per la produzione di energia elettrica.

    Paolo Baretta

    2007-10-01

    Full Text Available In Italy most of the research on worker and job mobility is carried out on social security (INPS administrative databases. We investigate the possibility of using the Italian Quarterly Labour Force Survey (RTFL as an additional source for currently measuring worker mobility. In principle, the motivation for using the RTFL is twofold: it covers (almost the whole employment, while INPS data are restricted to dependent employment in the private non-agricultural sector; it is timely, while INPS data are available with a lag of 4-5 years. The RTFL suffers, however, from a serious hindrance: the observation plan of the questionnaire provides fragmentary information on work histories. First, we identify and, to al large extent, control for the main reasons of discrepancy of worker mobility measures from the two sources, i.e., differences in the reference population and in the observation plan. Second, we propose a method capable of largely reconciling the evidence from the two sources. The ‘three-waves linkage’ method – as we call it – exploits the rotating panel design of the survey and uses linked data over three waves of the RTFL within a calendar year. Its salient features are presented and some main results are discussed. The empirical analysis is carried out for the year 1995. The evidence suggests that the three-waves linkage method, and thus the corresponding longitudinal datasets from RTFL, captures large part of the worker mobility documented by INPS databases: entirely as worker reallocation measures are concerned; with a significant, but moderate underestimation with respect to gross worker turnover.

Migration has therefore made a notable contribution to the acquisition and the use of English as a first, second and foreign language and to the burgeoning of new Englishes all over the world (Crystal 1997; Trudgill et al. 2002; Jenkins, 2003 thus questioning our traditional knowledge of language as a social projection of territorial unity held together by shared behavioral norms, beliefs and values. Specifically, by examining the communicative and translation processes which twelve interviewed interpreters, translators and language mediators were involved in during their interaction with newly-arrived migrants in Southern Italy, this paper addresses three main research issues concerning: a the use of English as a Lingua Franca (ELF in the practice of language and cultural mediation and the extent to which this language may be perceived either as a barrier or as a bridge, thus affecting the relationship between the mediator and the migrant and the shaping of the politics of hospitality in the Mediterranean; b the different linguistic and extra-linguistic strategies which mediators can adopt in the field of migration emergencies not only to serve communicative purposes, but also to humanize the migrants’ transfer to, and stay at the different camps across Italy; c the interviewed language mediators’ narratives as a testimony of negotiation, activism and resistance to the strict institutionalized protocols of Italian immigration policies. Finally, in this chapter, we also intend to investigate the extent to which the interviewed mediators form not a mere aggregation of individuals achieving the task of translation as a mere linguistic transfer, but a community of practice held together by a conscious and critical sense of the performative power of their words and their mediation conceived as a way to create meanings which form and transform human reality.

    Riassunto. L'approccio farmacologico personalizzato (tailored) rappresenta la terapia standard per i pazienti affetti da dolore oncologico, consentendo il controllo della sintomatologia in circa il 90% dei casi. Qualora tale strategia risulti inefficace è possibile ricorrere a più complesse tecniche, invasive o mini-invasive. Tuttavia, sia da parte dei pazienti sia degli operatori viene sottostimato il disagio psicologico sotteso al dolore oncologico e non si considerano i potenziali benefici dei trattamenti di supporto psicologico e riabilitativi nella gestione del dolore da cancro. Queste strategie non farmacologiche dovrebbero essere parte integrante di un più globale approccio multidisciplinare alla terapia del dolore, affiancando e amplificando gli effetti della terapia farmacologica. Tale breve rassegna narrativa ha la finalità di offrire una panoramica sul ruolo dei possibili interventi psicologici e riabilitativi atti al miglioramento della qualità della vita in pazienti affetti da dolore oncologico.

  13. Memoria antica e memoria indiana: discorso sulle divinità indigene nell’opera di Fray Juan Torquemada

    Directory of Open Access Journals (Sweden)

    Sergio Botta

    2016-12-01

    Full Text Available The Monarquía indiana - published in Seville in 1615 by Fray Juan de Torquemada - represented one of the most significant efforts to include Indigenous religions within a global view of religious diversity. As a product of a modern process of “mondialization”, the work of Torquemada reflected on the nature of Mesoamerican gods from a ground-breaking point of view. The Franciscan produced an evolution of the missionary methods and strategies used during the first part of colonial history. In the context of modern discourses on religion, the work of Torquemada does not represent only an "ethnographic" attempt to understand the complexity of Indigenous religions in order to promote evangelization. On the contrary, the missionary reflection on Indigenous gods established a key stage in the modern construction of a global theory of polytheism.

    2004-12-01

    Full Text Available Questa prospettiva - che trae le sue origini dal pensiero di G.H. Mead e di A. Schutz - sottolinea la natura simbolica delle interazioni umane e concepisce la devianza come risultato di un processo interattivo tra il soggetto che compie azioni, le norme che di tali azioni definiscono il grado di liceità, la reazione sociale all'infrazione delle norme e le modificazioni dell'identità personale legate ai processi di etichettamento, stereotipizzazione ed esclusione. Nelle opere di Lemert, Becker, K.T. Erikson e poi Goffman e Matza - i cosiddetti Neochicagoans - l'analisi delle cause è sostituita dall'esame dall'analisi dei processi sociali ed istituzionali di controllo sociale e, in generale, della complessa interazione tra soggetto deviante, norme e reazione sociale. In questo contributo, esaminiamo le peculiarità e le unità metodologiche dominanti di questo approccio che, a nostro giudizio, rappresenta ancora un punto di riferimento importante sia nella attuale analisi qualitativa applicata al settore della devianza, sia in qualità di "strumento" utilizzato dagli operatori istituzionali nell'ambito dell'interazione/relazione educativa con il soggetto deviante.

    Full Text Available Proton Pump Inhibitors (PPIs (Omeprazole, Lansoprazole, Pantoprazole, Rabeprazole and Esomeprazole, one of the most commonly prescribed classes of medications in the primary care setting, are considered a major advance in the treatment of acid-peptic diseases. In Italy PPIs are reimbursed by National Health Service on the basis of CUF (Commissione Unica del Farmaco 1 and 48 Notes. In 2002 and 2003 a significant increase in PPIs consumption and expenditure have been documented, showing differences between regions. The aim of this study is to investigate and monitor, at regional level, type and entity of PPIs use through a drug utilization study, evaluating prescribing behaviour and compliance of PPIs treatments with CUF Notes indications. The study has been carried out on a sample of 436 General Practitioners belonging to 22 Piemonte’s ASL (Aziende Sanitarie Locali. The data analysis shows that acid-related pathologies are significantly more common in patients with at least 50 years of age and the most frequent condition is represented by gastroesophageal reflux disease. Despite the general conditions of PPIs use by General Practitioners in terms of duration and dosage of therapy result in most cases (from 49% to 80% for duration and from 54% to 97% for dosage compliant with what proposed by CUF Notes, in some cases the same CUF Notes indications seem to be not observed. Consequently the Piemonte Region has decided to plan a guideline on PPIs rational use. Such guideline, expected to be introduced in the regional area, may also be considered as an instrument able to lead to a more appropriate expenditure for this drug class. Moreover, in order to control PPIs expenditure, pharmacoeconomic methodologies can be applied allowing to identify the most cost - effective active substance and therapeutic scheme, overcoming CUF Notes which consider all PPIs use under the same reimbursement conditions.

  5. L'impatto delle nuove tecnologie sulle forme di lavoro: una prospettiva europea (Technical Change and Employment: A European Perspective

    Directory of Open Access Journals (Sweden)

    Marcella Corsi

    2001-03-01

    Full Text Available This paper focuses on the role of knowledge within the process of growth and job creation in the European Union. Many features of the so-called knowledge-based economy are connected with the increasing use of information and communication technologies (ICT, that radically changes the conditions for the production and distribution of knowledge as well as its coupling to the production system. Technological change not only stimulates investment in physical capital but also brings to knowledge accumulation: human skills are required to implement, maintain, adapt and use technologies embodied in physical capital. Indeed, as new technologies become more widespread, certain skills may be less in demand--because many tasks once carried out manually are now performed by automated equipment--while the demand for workers able to maintain, program, and develop these sophisticated technologies rise. There is therefore concern that technological change may cause unemployment as the result of a mismatch between the demand for labour and the various skills of workers; in this way it may also increase the polarisation of society by widening the gap in income and employment opportunities between those whose skills have been displaced by new technology and those who create and use it.

    Full Text Available This article aims to analyze the medical and journalistic discourses built around prostitutes and cabarets during the period known as the Estado Novo (1937-1945 in the city of Aracaju. The New State was featured as one of the most authoritarian periods in the history of Brazil, in which Vargas was trying to control the population. As a strategy for their government measures were met, named some intervenors. One of his main goals was the quest for modernization, civilization and hygiene of the bodies, provided mainly with the help of medical health officers at the time. Placed as obstacles to modernizing project, prostitutes and cabarets were often bombarded by the local press, being characterized negatively. However, although such surveillance and stereotypes about these women and built sites, realize that they have never ceased to exist and were seen as a “necessary evil”.

    Michela Lo Feudo

    2016-12-01

    Full Text Available Come la maggior parte degli autori a lui contemporanei, il giovane Balzac cerca di farsi conoscere al grande pubblico e di guadagnarsi da vivere attraverso il giornalismo non politico - la cosiddetta petite presse -. Tra le numerose testate che hanno visto la sua partecipazione nel periodo che va dal 1824 al 1830, i settimanali La Silhouette e La Caricature si distinguono per forma e sostanza, fornendo indicazioni interessanti sulle scelte estetiche dell’autore in quegli anni: Balzac decide, infatti, di aderire a un tipo di pubblicazione innovativo e poco legittimato per l’epoca, possibile grazie alla recente diffusione della litografia. La Silhouette e la Caricature, fondate a cavallo della Rivoluzione di Luglio, basano in effetti la loro linea editoriale sulla sinergia fra testo e immagine come strumento per il racconto dell’attualità culturale e sulla centralità della satira visiva come codice espressivo privilegiato, inaugurando l’âge d’or della caricatura parigina portata in auge dai giornali di Philipon e dalle tavole di Grandville, Daumier e Cham. Attraverso l’analisi dei testi pubblicati da Balzac all’interno dei periodici in questione, si cercherà di capire se l’esperienza giornalistica, e in particolare il confronto con i linguaggi satirico-caricaturali, inducono l’autore a una riflessione sulla propria scrittura nel periodo in cui il progetto della Comédie humaine comincia a prendere forma. Un’esperienza, quella di Balzac, sicuramente pionieristica e capace di fornire spunti di riflessione per comprendere il rapporto tra letteratura e caricatura nell’Ottocento in Francia, rapporto che sarà rinnovato, nei decenni successivi, da autori come Gautier, Baudelaire, Champfleury e Vallès.

    1993-08-01

    Wars have been waged over oil and gold, but it is water that now poses the greatest potential for provoking conflict among nations-and the greatest need for new guarantees of cooperation. Athough water is a renewable resource, it is also a finite one. Nearly 40 percent of the world's population depends on river systems shared by two or more countries, leading to political hot spots, most critically in the middle east. This article describes in detail the water problems in the middle east, starting with the Jordan River basin, the Golan Heights, and the coastal aquifer, partly polluted. On the Sinai Peninsula the Nile River is the water source for nine countries, and the Tigris-Euphrates, although still providing water in relative abundance, is prey to the failure of Iraq, Syria, and Turkey to reach water-sharing agreements. Discussion includes the possibilities of turning the win-lose situations into win-win situations by appropriate water management and the problem of lack of a clear legal framework for settling disputes.

    Clearwater Pool Technologies employs NASA-developed silver/copper ionization to purify turtle and dolphin tanks, cooling towers, spas, water recycling systems, etc. The pool purifier consists of a microcomputer to monitor water conditions, a pair of metallic electrodes, and a rheostat controller. Ions are generated by passing a low voltage current through the electrodes; the silver ions kill the bacteria, and the copper ions kill algae. This technology has found broad application because it offers an alternative to chemical disinfectants. It was originally developed to purify water on Apollo spacecraft. Caribbean Clear has been using NASA's silver ionization technology for water purification for more than a decade. Two new products incorporate advancements of the basic technology. One is the AquaKing, a system designed for areas with no source of acceptable drinking water. Another is the Caribbean Clear Controller, designed for commercial pool and water park applications where sanitizing is combined with feedback control of pH and an oxidizer, chlorine or bromine. The technology was originally developed to purify water on Apollo spacecraft.

    The Thermal and Electrical Conductivity Probe on NASA's Phoenix Mars Lander detected small and variable amounts of water in the Martian soil. In this schematic illustration, water molecules are represented in red and white; soil minerals are represented in green and blue. The water, neither liquid, vapor, nor solid, adheres in very thin films of molecules to the surfaces of soil minerals. The left half illustrates an interpretation of less water being adsorbed onto the soil-particle surface during a period when the tilt, or obliquity, of Mars' rotation axis is small, as it is in the present. The right half illustrates a thicker film of water during a time when the obliquity is greater, as it is during cycles on time scales of hundreds of thousands of years. As the humidity of the atmosphere increases, more water accumulates on mineral surfaces. Thicker films behave increasingly like liquid water. The Phoenix Mission is led by the University of Arizona, Tucson, on behalf of NASA. Project management of the mission is by NASA's Jet Propulsion Laboratory, Pasadena, Calif. Spacecraft development is by Lockheed Martin Space Systems, Denver.

  12. Optimal Allocation of Water Resources Based on Water Supply Security

    2016-06-01

    Full Text Available Under the combined impacts of climate change and human activities, a series of water issues, such as water shortages, have arisen all over the world. According to current studies in Science and Nature, water security has become a frontier critical topic. Water supply security (WSS, which is the state of water resources and their capacity and their capacity to meet the demand of water users by water supply systems, is an important part of water security. Currently, WSS is affected by the amount of water resources, water supply projects, water quality and water management. Water shortages have also led to water supply insecurity. WSS is now evaluated based on the balance of the supply and demand under a single water resources condition without considering the dynamics of the varying conditions of water resources each year. This paper developed an optimal allocation model for water resources that can realize the optimal allocation of regional water resources and comprehensively evaluate WSS. The objective of this model is to minimize the duration of water shortages in the long term, as characterized by the Water Supply Security Index (WSSI, which is the assessment value of WSS, a larger WSSI value indicates better results. In addition, the simulation results of the model can determine the change process and dynamic evolution of the WSS. Quanzhou, a city in China with serious water shortage problems, was selected as a case study. The allocation results of the current year and target year of planning demonstrated that the level of regional comprehensive WSS was significantly influenced by the capacity of water supply projects and the conditions of the natural water resources. The varying conditions of the water resources allocation results in the same year demonstrated that the allocation results and WSSI were significantly affected by reductions in precipitation, decreases in the water yield coefficient, and changes in the underlying surface.

    Full Text Available Formation of water hammer, its consequences and possible protection measures are rarely topics, however the problem is significant. Water hammer can form in water supply and pressurized sewage networks, for various reasons. The article presents short theory of water hammer and methodology for calculation of specific parameters. Research of water hammer was performed in real water supply and sewer networks of country. Simulation of water hammer was carried out by turning on and off water pumps in pumping station. Successful measurement of water hammer depends on accuracy of the measurement equipment, therefore during the research surge wave fluctuations were measured with especially high resolution pressure meters. Detailed analysis of water hammer and selection of protecting equipment hydraulic model of water supply network was created. Protection against water hammer helps to avoid breaking of the water network and extend operation time.

    Friedman, S. R.; Khalil, M.; Taborek, P.

    2013-11-01

    Optical images were used to study the wetting behavior of water on graphite, sapphire, and quartz along the liquid vapor coexistence curve from room temperature to 300°C. Wetting transitions were identified by the temperature at which the contact angle decreased to zero and also by the disappearance of dropwise condensation. These two methods yielded consistent values for the wetting temperatures, which were 185°C, 234°C, and 271°C for water on quartz, sapphire, and graphite, respectively. We compare our results with the theoretical predictions based on a simplified model of the water-substrate potential and sharp interfaces.

    The relationship between water and activated sludge components was examined. Reevaluation of published data on freezing point depression, drying rates and dewatering has been performed. The basis of this has been the assumption that the water/sludge relationship is considered to be a colligative...... effect. Since the results indicate this to be the case, we suggest that the published concepts of "pools of water" are false. Data on swelling properties of EPS as a function of pH suggests that the colligative properties are largely determined by the counterions of charged polymers and surfaces....

    Space Spin-Offs, Inc. under a contract with Lewis Research Center and Marshall Space Flight Center produced a new water-powered saw that cuts through concrete and steel plate reducing danger of explosion or electric shock in rescue and other operations. In prototype unit efficient water-powered turbine drives an 8 inch diameter grinding disk at 6,600 rpm. Exhaust water cools disk and workpiece quenching any sparks produced by cutting head. At maximum power, tool easily cuts through quarter inch steel plate. Adapter heads for chain saws, impact wrenches, heavy duty drills, and power hack saws can be fitted.

    We present the molecular simulation study of the behavior of water and sodium chloride solution confined in lizardite asbestos nanotube which is a typical example of hydrophilic confinement. The local structure, orientational and dynamic properties are studied. It is shown that the diffusion coefficient drops about two orders of magnitude comparing to the bulk case, and water in lizardite asbestos tubes experiences vitrification rather then crystallization upon cooling in accordance with the results for some other hydrophilic confinements. The behavior of sodium chloride solutions also considered and the formation of double layer is observed. It is shower that both sodium and chlorine have larger diffusion coefficients then water.
