    Full Text Available Mentre la scienza costituzionalistica si interroga da qualche tempo sul cambiamento del ruolo del Capo dello Stato nel nostro ordinamento costituzionale - specie da quando il settennato presidenziale si svolge “all’interno di una dinamica bipolare e maggioritaria nella forma di governo parlamentare” - la dottrina ecclesiasticistica non ha avuto motivo di approfondire in modo particolare se, nel campo di ricerca proprio, vi fosse un ruolo specifico del Presidente della Repubblica, sia per l’aspetto della tutela dei diritti inviolabili della persona interessati dal fattore religioso, sia nei profili delle relazioni e della disciplina dei rapporti Stato–confessioni, e se possa ritenersi in parte mutato. Il passaggio dalla monarchia alla Repubblica, è noto, ha ridotto di molto le di lui competenze nella materia “ecclesiastica”, ed una svolta determinante a questo processo storico è stata impressa dalla Costituzione. Quel processo, si è detto in passato, “non ha ancora esaurito il suo iter”; e, più di recente, si è potuto sottolineare che, nella nostra materia, “rimane in ogni caso estranea alla figura costituzionale del Capo dello Stato … la titolarità di una qualsiasi funzione di indirizzo politico in senso stretto”, restando il suo compito limitato a quello più generale di rappresentante dell’unità nazionale e di “custode” della Carta ed a quelli, di ridotta valenza, concernenti alcuni profili amministrativi connessi all’attività normativa del Governo.

    Special importance is given to some producer country (Saudi Arabia, Iraq, Kuwait, Iran, United Arab Emirate, Venezuela) that determine the trend of petroleum price. These countries have about the 70% of world petroleum reserves against the 3% of world population. [Italian] Nello studio dell'instabilita' del mercato internazionale del petrolio, si e' finora attribuita particolare importanza al ruolo che svolgono alcuni Paesi produttori, in particolare i sei grandi produttori (Arabia Saudita, Irak, Emirati Arabi Uniti, Kuwait, Iran e Venezuela) che sono in grado, anche associandosi ad altri (OPEC), di determinare, attraverso l'autoimposizione delle quote di produzione, gli andamenti del prezzo del petrolio, che si ripercuotono assai negativamente sulla complessiva economia petrolifera mondiale. A tal riguardo occorre, infatti, avere sempre presente che questi Paesi possiedono circa il 70% delle riserve mondiali di petrolio, pur rappresentando meno del 3% della popolazione mondiale. Da qui anche l'interpretazione del fenomeno dell'instabilita' come conseguenza di una contrapposizione sostanzialmente politica fra Paesi capitalistici industrializzati e Paesi produttori di petrolio. La consapevolezza della forte rigidita' della domanda di petrolio, unitamente alla sua concetrazione in determinate aree geografiche, prevalentemente in Medio Oriente, ha reso quello del petrolio un argomento con forti connotazioni politiche, contrapponendo due sistemi socio-culturali, quello occidentale e quello arabo, che fino agli anni '60 non avevano particolari motivi per essere in disaccordo, ma che hanno attraversato molti momenti caldi, dopo la crisi israeliana e la crescente necessita' di energia per l'economia globale. Con il passare del tempo tale contrapposizione, legata anche alla volonta' da parte dei Paesi produttori di sfruttare al massimo le rendite petrolifere, ha portato alla costituzione di societa' nazionali

Conclusioni: per un “ricupero” degli elementi originali della funzione consultiva nella vita della Chiesa. AbstractThe aim of this paper is to examine the role played by the consultation principle in the life of the Church. Indeed, Pope Francesco underlined the importance of this concept and – from the beginning of his pontificate – widely used this “decision-making model”. Moreover, he based the ecclesiastical reform on this principle, in particular with the creation of the new council of cardinals, with the task to assist the holy father in the government of the Universal Church and to study possible revision of the apostolic constitution “Pastor Bonus” on the Roman Curia.Through a reflection that moves from the origins of the principle and its renewed strength during the Second Vatican Council, the paper allows concluding that the consultative principle plays a central role in the life of the church, even greater than that assumed within the jurisdiction of the states. This belief opens up further studies, able to deepen the original elements of the ecclesiastical consultation practice, with the aim of developing this model of government.

    delle principali lesioni interne con adeguata e istantanea pianificazione del trattamento chirurgico d'emergenza e/o rianimativo di supporto. Scopo del presente lavoro e' quello di illustrare il ruolo dell'esame TC nel documentare le molteplici e complesse lesioni pleuropolmonari, cardiovasali e della parete toracica, la cui compromissione si manifesta con semeiologia specifica e acuta del tutto diversa da quella della traumatologia toracica classica. Negli ultimi 4 anni sono stati osservati presso il pronto soccorso dell'Ospedale Loreto Mare di Napoli 76 casi di ferite d'arma da fuoco, di cui 26 con interessamento toracico: 25 maschi e una femmina (eta' media 32 anni, compresa tra 17 e 48 anni). Tutti i pazienti sono stati sottoposti a TC d'urgenza del torace con iniezione endovenosa di mdc e con tecnica angio-TC e in presenza del medico rianimatore con monitoraggio delle funzioni vitali e dello stato di shock. In 4 casi e' stato completato con studio TC dell'addome e pelvi per la presenza di lesioni associate toraco-addominali e in 3 casi con TC del cranio per lesioni encefaliche da proiettile. Il radiogramma del torace consente di documentare i danni maggiori toraco-polmonari d'arma da fuoco, anche se non permette la valutazione precisa delle lesioni cardiache e dei grandi vasi e dei pneumotoraci minimali. L'associazione di alterazioni traumatiche cranio-addominali concomitanti indirizza l'approccio diagnostico verso una metodica di primo livello come la TC, in grado di fornire con un unico esame il giudizio immediato sul grado di compromissione, panoramicita' e gravita' delle lesioni da arma da fuoco polmonari e extratoraciche. Cio' consente di instaurare la terapia tempestiva e mirata, sia essa chirurgica o di supporto rianimativo, evitando ritardi diagnostici e di gestione terapeutica sicuramente dannosi per la sopravvivenza del paziente.

    Aim of this retrospective study was to assess the capability of contrast-enhanced helical computerised tomography (CT) in sigmoid diverticulitis, especially relative to selection of the appropriate treatment. The findings of 41 patients were reviewed from 1998 to 1999 June. Contrast-enhanced helical CT is the imaging modality of choice in assessing mild or severe acute diverticulitis because it provides useful information for appropriate treatment planning in the emergency setting. This technique is most useful in questionable cases and in patients with suspected severe diverticulitis where a choice must be made between different treatment options. [Italian] Scopo di questo studio retrospettivo e' illustrare i molteplici aspetti radiologici della flogosi diverticolare sigmoidea con tomografia computerizzata (TC) spirale, con specifico riguardo alle implicazioni terapeutiche che scaturiscono dall'analisi e dal confronto dei reperti TC con i riscontri clinici e chirurgici. Sono analizzati e discussi i risultati dello studio di 41 pazienti consecutivi con diverticolite del sigma esaminati dal giugno del 1998 al giugno del 1999. La TC spirale ha fornito dettagli precisi sul danno anatomo-chirurgico dell'ansa e sulle strutture limitrofe coinvolte consentendo di differenziare la diverticolite lieve da quella grave. Il suo ruolo si configura nei pazienti critici difficilmente classificabili e nelle sospette diverticoliti gravi o complicate per la molteplicita' delle scelte terapeutiche.

L’analisi dell’esperienza mostra come le attività proposte secondo questa metodologia abbiano spinto gli studenti, durante la lezione, ad immedesimarsi ciascuno in un particolare personaggio e come questo abbia influenzato il coinvolgimento affettivo e comunicativo degli studenti, migliorandone la produzione linguistica e fungendo da stimolo a valorizzare le loro conoscenze pregresse.     Learning according to roles: a process drama exerience for the teaching of italian to students in the stranimedia project   This article discusses how, within the process drama methodology applied to foreign language teaching, the identification through the dramatic role influences the linguistic production of students.  After the first theoretical part where process drama is compared to more traditional roleplay activities used in the communicative approach, there is a second part which analyzes a cycle of lessons conduced using process drama, carried out at the University degli Studi di Milano with a class of Chinese mothertongue students in June 2010. The analysis of the experience shows how the activities proposed uing this method pushed the students to identify with their characters and this in turn influenced the emotional and communicative involvement of the students, improving their linguistic production and acting as a stimulus for giving

    Purpose. To evaluate the role and the effectiveness of interventional radiology in the treatment of renal transplant complications. Materials and methods. From 1996 to 2004 a total of 288 kidney transplants from cadavers were performed in our Institute. The kidney was always collocated in iliac fossa by creating a vascular anastomosis with the external iliac artery and vein; in all cases the ureter was implanted into the recipient bladder. During the follow-up, 34 complications were observed. Twenty-seven complications in 25 patients (20 males and 5 females; age 35-65 years) were treated by a radiologic procedure: 9 renal artery stenosis and 1 native external iliac artery stenosis (by PTA), 5 ureteral obstructions (by nephrostomy and ureteral stenting), 8 ureteral leaks (by nephrostomy, in 2 cases associated to ureteral stenting) and 4 limphoceles (by percutaneous ultrasound-guided catheter drainage). Results. Primary technical success was obtained in 20/27 cases (74%). Success was obtained with a second interventional procedure in 3/27 cases, 2 limphoceles and 1 ureteral fistula (secondary technical success: 85.2%), with a clinical final success in 23/27 cases (85.2%). We observed a peri-procedural complication rate of 3.7% (1 renal artery post-PTA dissection during a restenosis treatment). Four cases (1 renal arterial post-PTA dissection, 1 ureteral obstructions, 1 ureteral leak and llimphocele) needed a surgical correction (14.8%). Conclusions. Interventional radiology is the first therapeutic approach to treat renal transplant complications. It shows good technical and clinical results and a low complication rate. Surgery had to be considered only if minimally invasive procedures are infeasible or ineffective. [Italian] Scopo.

    mammography, 73.5% for ultrasonography and 90.9% for cytology (97.7% if inadequate samples were excluded), and overall sensitivity would be 96.1%. Conclusions: Differential diagnosis of breast cancer in women aged under 36 years is difficult, sensitivity being lower as compared to older women, with the only exception of cytology. The association of multiple tests (diagnostic imaging and cytology) is crucial to achieve an acceptable false negative rate. In particular, the extensive use of cytology in the presence of an even minimal doubt at palpation and/or imaging is strongly recommendable. Sensitivity must be calculated on the basis of an independent pathology registry, and false negatives must be defined within a given period after the test. Analysis limited to tests performed immediately before diagnosis leads to a biased over-estimation of sensitivity. [Italian] Scopo: Valutare la sensibilit� per carcinoma mammario delle diverse metodologie diagnostiche impiegate in una serie consecutiva di donne di et� inferiore ai 36 anni. Materiale e metodi: Analisi di 155 soggetti, con carcinoma incidente nel Registro Tumori Toscano dal 1985 al 2000. la sensibilit� delle metodiche � valutata rispetto all'esame pi� recente eseguito nell'anno precedente la diagnosi, in funzione di diverse variabili, quali le dimensioni del tumore e il periodo temporale. Risultati: La sensibilit� � risultata del 70.3% per l'esame clinico, 76.0% per la mammografia, 69.1% per l'ecografia e 80.6% per la citologia (86.2%, escludendo i prelievi inadeguati). La sensibilit� dipende dallo stadio per la clinica (pT1=60.6%; pT2=4=86.4%; {chi}2=10.2, p=0.001) e per l'ecografia (pT1=61.9%; pT2=4=92.0%; {chi}2=5.7, p=0.001) e dalla densit� radiologica del seno per la mammografia (densit� 50-100% =75.5%; 0-50 densit�=91.3%; {chi}2=1.85, p<0.17). Nei 112 casi esaminati con clinica, mammografia e citologia i tre metodi hanno avuto sensibilit� rispettivamente del 78.5%, 75

    Full Text Available La relazione propone alcune riflessioni sul ruolo della musica d’arte contemporanea nella pedagogia della complessità. Le teorie della complessità formano un’area di pensiero ormai largamente consolidata nelle scienze umane e sociali. Tali teorie sottolineano l’importanza di concetti come discontinuità contraddizione non-linearità molteplicità caso caos, sia nei fenomeni naturali che in quelli culturali. In una serie di recenti pubblicazioni, l’epistemologo francese Edgar Morin ha elaborato una pedagogia basata sulla teoria della complessità. La musica d’arte contemporanea comprende un vasto repertorio di opere sulle quali poter fondare una pedagogia e una didattica della complessità in musica. La relazione suggerisce un possibile esempio di impiego e di trasposizione didattica di un brano, B.A.C.H. per pianoforte solo, opera del compositore italiano Aldo Clementi, risalente al 1970.

Choosing among them is not easy, and several issues need to be considered, such as the clinical situation, (i.e. present symptoms and past medical history, age of patients, if it is first diagnosis or follow-up after treatment.., sensitivity and specificity of the test, the cost-effectiveness of the testing strategy, the availability of the test, the local expertise . Since the “Ideal test” is not relied, the gastroenterologist or clinician as well, has the important role of deciding which test to employ. A good knowledge of advantages and vantages of each test is so necessary to make the best choose as possible.

    Full Text Available This paper addresses the topic of rewriting in journalistic discourse by examining the typical textual features of the press release, one of the most commonly used journalistic sources. Journalism has long being recognised as being based on reproductive writing practices (Jakobs 2003, as it consists, as Bell (1991: 41 puts it, “of previously composed text reworked into text news”. In this process of rewriting, a key role is played by sources. While their use (and occasional manipulation on the part of journalists has been variously explored in the literature, less has been done to investigate the textual features of documents specifically designed to serve as sources, most notably press releases. The paper provides a description of the characterising features of the genre of the press release, highlighting the essentially “preformulated” nature (Jacobs 1999 of these documents, i.e. the fact that their formal traits, as well as the structuring of their content, are strategically designed to facilitate reproduction. The paper concludes that while the re-use of textual material from sources is a crucial aspect of journalistic text production, care should be taken to distinguish between rewriting and uncritical textual reproduction: although recourse to the latter has been growing exponentially over the last decade due to an increasing shortening of news production cycles that has turned journalists into “processors rather than generators of news” (Lewis et al. 2008: 27 under constant pressure to continuously “churn out” (Davis 2008 stories, a renewed attention to rewriting as a key component of journalistic text production practices should be encouraged.

Nell’esaminare i principali interventi normativi attuati da inizio secolo, l’Autore mette in evidenza le scelte di metodo e gli elementi di continuità che accomunano i vari provvedimenti, individuandoli nell’affannosa ricerca del punto di equilibrio tra flessibilità e garantismo. La riflessione si chiude con alcuni interrogativi sulle ultime linee di riforma del mercato del lavoro e con l’auspicio che, anche al cospetto delle imprescindibili ragioni dell’economia, il diritto del lavoro possa continuare a svolgere il proprio tradizionale ruolo di disciplina di tutela della persona.   Abstract - The author analyzes, with a critically oriented approach, the development of the employment law, in the light of the current economic and financial crisis. In examining the main regulatory measures implemented since the beginning of the century, the author highlights the methodological choices and the elements of continuity that unite the various measures, focusing them in a hard research of a point of balance between flexibility and security. The discussion concludes with some questions about the last lines of the reform of the labor market and with the hope that, even in the face of compelling reasons of economy, labor law can continue to play its traditional role of governing the protection of person.

    important sonographic alteration was the gradual reduction in hilar echogenicity (seen in 100% metastatic nodes); conversely, hilar denting of irregularities, as well as dimensional criteria, proved to be poorly specific. Conclusions: The sonographic assessment of axillary and internal mammary chain nodes, possibly in addition to core biopsy, improve the preoperative evaluation of breast cancer patients scheduled for conservative surgery of the breast (quadrantectomy) and the axilla (sentinel node biopsy). US findings suspicious for metastatic involvement of axillary lymph nodes should be considered as an exclusion criterion for sentinel node biopsy. A more widespread use of axillary node biopsy and an accurate sonographic evaluation of the excised lymph node increase the specificity of the procedure, allowing a better correlation between sonographic findings and definitive histology.

    A torsional-type analytical balance designed to arrive at its equilibrium point more quickly than previous balances is described. In order to prevent external heat sources creating air currents inside the balance casing that would reiard the attainment of equilibrium conditions, a relatively thick casing shaped as an inverted U is placed over the load support arms and the balance beam. This casing is of a metal of good thernnal conductivity characteristics, such as copper or aluminum, in order that heat applied to one portion of the balance is quickly conducted to all other sensitive areas, thus effectively preventing the fornnation of air currents caused by unequal heating of the balance.

    Rilevanza del tema: i costi sempre più alti affrontati attualmente dai sistemi sanitari nei paesi industrializzati sono in parte il risultato dei crescenti costi della farmacoterapia. Dato che la sempre più alta aspettativa di vita nella popolazione determina un aumento della prevalenza di malattie, l’utilizzo di linee guida a supporto della farmacoterapia è essenziale per sistemi sanitari efficienti e dai costi sopportabili.

    La terapia farmacologica è infatti uno dei pilastri dell’odierna assistenza sanitaria. La ricerca farmacoepidemiologica, inoltre, fornisce gli strumenti per un razionale utilizzo dei farmaci nella pratica medica. Lo studio dell’utilizzo di farmaci è necessario per l’efficacia ed il controllo della moderna farmacoterapia.

    Future necessità di ricerca: dalla ricerca ci si attende che sviluppi strumenti rapidi ed attuabili per ottenere un’informazione affidabile sull’uso dei farmaci in rapporto alla quantità, ai costi, alle indicazioni mediche e così via. Possibili realizzazioni pratiche: la disponibilità on-line di informazioni sull’utilizzo di farmaci in alcuni Paesi europei, insieme alla capacità di elaborazione dei moderni software elettronici e a nuovi programmi di analisi statistica rendono le analisi comparative di farmacoepidemiologia realizzabili quasi in tempo reale.

    1997-11-01

    During last years, energy crops have been envisaged as an interesting alternative to biomass residues utilization as renewable energy source. In this work, main parameters used in calculating the energy balance of an energy crop are analyzed. The approach consists of determining energy equivalents for the different inputs and outputs of the process, thus obtaining energy ratios of the system, useful to determine if the energy balance is positive, that is, if the system generates energy. Energy costs for inputs and assessment approaches for energy crop yields (output) are provided. Finally, as a way of illustration, energy balances of some representative energy crops are shown.

    Full Text Available L?Arvicola delle nevi Chionomys nivalis, a causa della sua particolare nicchia ecologica costituita, nella sua componente spaziale, dai suoli pietrosi nei cui interstizi vive, viene di norma considerata una preda poco rappresentata nelle catene trofiche. In Italia, eccettuato un dato incerto di cattura da Buteo buteo, è risultata predata da cinque specie di serpenti (Coronella austriaca, Elaphe longissima, Vipera aspis, V. berus, V. ursinii, sei di uccelli (Aquila chrysaetos, Strix aluco, Bubo bubo, Aegolius funereus, Asio otus e cinque di mammiferi (Vulpes vulpes, Mustela nivalis, M. erminea, Martes sp., Felis catus.

Valentino alla Muta (BZ, Mustela erminea nel Parco Naturale Adamello-Brenta (TN con percentuali piuttosto consistenti, rispettivamente del 69.6%, 60.71% e 35.89%. In uno studio su Vulpes vulpes nel Parco Nazionale Gran Paradiso (TO-AO è risultata essere la preda dominante tra i roditori. Sempre nella stessa area, è interessante la predazione da Aegolius funereus per la quale risulta, dopo Clethrionomys glareolus, la preda più rappresentata (27.97% malgrado, da uno studio di trappolamento di micromammiferi effettuato intorno all?area di nidificazione, risulti assente rivelando così un comportamento esplorativo del rapace diretto proprio alla ricerca dell?arvicola delle nevi. Da una prima analisi sembrerebbe dunque da rivalutare il ruolo di questo roditore come preda, anche considerando il contributo in biomassa che può rappresentare. Su un totale di 184 dati reperiti sulla presenza della specie in Italia, 28 (15.2% derivano da residui di predazione. Benché non risulti un quantitativo alto comparato ad altri micromammiferi è comunque significativo

    Full Text Available The use of the emblems spreads within the cities of Europe in the first centuries after the Year 1000: the paper shows how this social phenomenon is related to the beginning of the individualization process. The signaletic and the symbolic practices related to the use of the emblems develop in parallel with the construction of the personal identity and the structuring of the social interdependence. With the emergence of both Court society and scientific sensitivity, the rapid araldic transformation of the emblems gives to the European ruling class the definitive monopoly of this extralinguistic code, erasing his early democratic meaning of personal autonomy expression.

    Incineration, landfill and recycling are three main strategies to face the problem of waste disposal, and may co-exist. However, it is essential to encourage recycling, the only sustainable practice among the three cited above which avoids the existence itself of wastes by transforming possible waste materials in a series of products. Composting, as sustainable transformation of potential wastes in organic fertilizers, tunes up with sustainable agriculture, and must be optimised and developed. The three requisites needed in order that agriculture can be considered sustainable are discussed, and the use of compost is shown to enhance sustainability, not only of the agricultural activity, but of a more general context of sustainable society.

  1. "Translation does not often demand genius": George Eliot e il ruolo del traduttore vittoriano

    Directory of Open Access Journals (Sweden)

    Michela Marroni

    2016-01-01

    Full Text Available George Eliot’s formative years were characterised by her intense activity as a translator which she carried out with methodological scrupulousness and profound sense of responsibility. In her ambition to make a name for herself in the English cultural world she understood, from a very early age, that translation would be the best means of expanding her knowledge while measuring herself against original texts that had made an important impact on European culture. Although Eliot was proficient in several modern and ancient languages (namely, German, French, Italian and Spanish, Latin, Greek and Hebrew, most of her translations were from German. It was with her translation of Strauss’s Das Leben Jesu that she proved her skill as a translator. Through this work her name also became familiar in Victorian theological debates. No less important was her translation of Feuerbach’s Das Wesen Christentums which, in many respects, led to her acceptance into the most advanced literary and philosophical circles in London. On the strength of this, in 1855, Eliot published the essay Translations and Translators which she wrote from her point of view as an affirmed journalist who was perhaps already contemplating the idea of becoming a novelist. The essay reveals both Eliot’s acute awareness of translation as a demanding work and of the role of the translator as a mediator between different linguistic and cultural realities. By indicating Germany as an example to follow, since in that nation the great poets and novelists translated the English classics into German, Eliot bluntly declared that the translator must work with a sense of responsibility and moral commitment and always aim for perfection.

    Full Text Available The Martial Este Glacier in southern Tierra del Fuego was studied in order to estimate the surface mass balance from 1960 until 2099. For this reason a degree-day model was calibrated. Air temperature and precipitation data obtained from 3 weather stations as well as glaciological measurements were applied. The model was driven using a vertical air temperature gradient of 0.69 K/100 m, a degree-day factor for snow of 4.7 mm w.e. K−1 day−1, a degree-day factor for ice of 9.4 mm w.e. K−1 day−1 and a precipitation gradient of 22%/100 m. For the purpose of surface mass balance reconstruction for the time period 1960 until 2006 a winter vertical air temperature gradient of 0.57 K/100 m and a summer vertical air temperature gradient of 0.71 K/100 m were added as well as a digital terrain model. The key finding is an almost continuous negative mass balance of −772 mm w.e. a−1 throughout this period. While the calculation of the mass balance for the period 1960–2006 is based on instrumental records, the mass balance for the years 2007 until 2099 was estimated based on the IPCC SRES A2-scenario. To accomplish this estimation, the dataset of the global climate model HadCM3 was statistically downscaled to fit local conditions at Martial Este Glacier. Subsequently, the downscaled air temperature and precipitation were applied to a volume-area scaling glacier change model. Findings reveal an enduring deglaciation resulting in a surface area reduction of nearly 93% until 2099. This implicates that the Martial Este Glacier might be melted off at the beginning of the 22nd century.

    cosecha. Se condujo un experimento de niveles de N de larga duración en condiciones de secano, con cuatro ciclos de plantación y 24 cosechas. Se empleó un suelo Ferralítico Rojo típico éutrico. Antes de la plantación y después de algunas cosechas, se tomaron muestras de suelo (0.00-0.30 m en cada parcela y se les determinó la materia orgánica por el método de Walkley y Black. La variación del C orgánico del suelo en el tiempo se modeló mediante la ecuación Corg= a+bt1/2. La cantidad de C capturado anualmente por tratamiento se calculó sobre la base de la cantidad total de biomasa aérea expresada en base seca y % C en la biomasa. La estimación del C total liberado a la atmósfera se realizó considerando la pérdida de C orgánico del suelo y el emitido por efecto de la quema de hojas secas. El balance final del C en el agroecosistema se calculó sumándole al total emitido a la atmósfera el que se exportó del campo con los tallos y restando el resultado del C capturado anualmente por tratamiento. El C orgánico del suelo disminuyó aún sin aplicar fertilizantes minerales (2.05 a 1.43 %. No se encontró efecto del N aplicado sobre la disminución del C orgánico del suelo. El C total perdido del agroecosistema cañero, considerando el exportado por los tallos, resultó similar al capturado por la biomasa aérea, por lo que el balance neto tendió a cero. Como que en la estimación no se tuvo en cuenta el C fijado por las raíces y la cepa de la caña de azúcar, puede pensarse que el balance neto fue positivo hacia la captura. No obstante, se demostró que si bien no se manifestó contaminación atmosférica por el incremento de la concentración de C, sí se deterioró la fertilidad del suelo

    bronchiectasis. [Italian] Scopo di questo lavoro e' valutare il ruolo della TC nello studio delle lesioni polmonari nei pazienti con Mycobacterium xenopi e AIDS. Sono stati esaminati 12 pazienti con eta' compresa tra 30 e 46 anni, con malattie polmonari da Mycobacterium xenopi e AIDS. In tutti i pazienti sono stati riscontrati un livello ematico di CD4+ inferiore a 250 cellule/{mu}l e presenza del Mycobacterium xenopi nell'espettorato. I quadri TC sono stati valutati da tre radiologi in sessioni indipendenti e la diagnosi definitiva e' stata ottenuta in presenza del quarto radiologo. L'esame TC del torace ha evidenziato nel 66% dei pazienti la presenza di infiltrato parenchimale associato a strie basali bilaterali nel 16% dei casi. L'infiltrato parenchimale e' risultato monolaterale nel 41% dei casi e ha interessato piu' frequentemente il lobo inferiore di destra. In 5 pazienti (41%) e' stata descritta la presenza di interstiziopatia reticolare bilaterale e in uno (8%) di micronodulazione. Nel 33% dei pazienti e' stata riscontrata adenopatia mediastinica. In 2 pazienti e' stata segnalata la presenza di enfisema pre-esistente. In un paziente sono state osservate bronchiectasie. A seguito della diffusione dell'infezione da HIV la malattia polmonare da Mycobacterium xenopi e' sempre piu' frequentemente oggetto di osservazione clinico-radiologica. Le lesioni polmonari nei pazienti con malattia da Mycobacterium xenopi e AIDS assumono aspetti e localizzazioni sostanzialmente aspecifiche, che devono essere considerate dal radiologo clinico ai fini del corretto inquadramento terapeutico. Il riscontro frequente dell'infiltrato parenchimale e insieme l'assenza di lesioni di tipo cavitario possono essere attribuiti alla scarsa capacita' dei pazienti con AIDS di sostenere una risposta floristica adeguata. La distribuzione delle lesioni polmonari ha mostrato predilezione per i lobi inferiori con teressamento

    Full Text Available La amplia mecanización e intensificación de la producción constituye un camino fundamental para el desarrollo ulterior de la agricultura y la satisfacción de las necesidades crecientes del país en productos agrícolas. El parque de máquinas agrícolas y tractores con que cuenta en la actualidad nuestra agricultura está muy deteriorado y ha cumplido el doble de su vida útil de trabajo, por lo que se requiere de su uso más racional, organizándolo adecuadamente y disponiendo de un sistema de instalaciones y personal calificado para su explotación, asistencia técnica y conservación. Por tal motivo se hace necesario utilizar métodos de organización que contribuyan al uso más eficiente de la maquinaria. Uno de esos métodos de organización es la realización del cálculo del déficit/superávit (balance de los medios mecanizados.El balance de maquinaria como forma organizativa de programación se puede utilizar, además, para la realización del análisis económico, por cuanto contribuye a la selección de las tecnologías más racionales.

    Full Text Available Viceroy Jose Fernando de Abascal is a polemical figure in the peruvian historiography. The studies that through nineteenth and twentieth centuries evaluated his government and also the power space of his time were conditionated by many juncture circunstances that are the main reflection of this historiographic balance. This article concentrated on the peruvian nationalism of XIXth and XXth centuries, on the social theory of the emancipation arised in the Spain of general Francisco Franco, on the socio-economic interpretation appeared under the celebration of the Sesquicentenary of the peruvian independence, and finally on the recent researchs made under political culture perspective.

    El virrey José Fernando de Abascal es una figura polémica dentro de la historia peruana. Los estudios que a lo largo del siglo XIX y XX se centraron en evaluar su obra de gobierno y el espacio del poder que este personaje fomentó estuvieron condicionados por una serie de circunstancias coyunturales sobre los que se reflexiona en este balance historiográfico. Este texto se conduce por el nacionalismo peruano del siglo XIX y de mediados del siglo XX, por la teoría social de la emancipación surgida en pleno régimen franquista, por el planteamiento socio-económico aparecido con ocasión de la celebración del sesquicentenario de la independencia peruana y por las más recientes interpretaciones desde la perspectiva de la cultura política.

    Niels Bohr rifiutava ogni idea troppo conservatrice con il lapidario giudizio "Non è abbastanza folle". La fisica moderna ha dimostrato l'inefficacia del buon senso per costruire teorie o comprendere particolari risultati sperimentali. In rottura con l'esperenzia comune, ha contrapposto l'inaudito all'abitudine, i concetti delicati agli archetipi classici, le ipotesi piu ardite alle apparenze rassicuranti.

    Full Text Available In a traditional Catholic country like Italy, the job of school teacher seems to be tailored just for women, in order to preserve quietly both roles of mother and working person, in the imagery of people who don’t work in the school world at least. This happens because the school has always been the second space of traditional display regarding gender differences, and the only one recognised as such by society, after the family. There’s no place like school where Italian women have been free to exhibit and make the most of their own relational competencies, even their sex difference, getting the same payment reserved for men but anyway lower than payments existing in other service sectors. Italy is the country where the family-school pair has assumed a legendary status for decades, with the woman usually seen as a link between these two environments; and maybe that’s exactly the reason why the school has become the stage where each and every metamorphosis of family is set up and the female presence gets its identity as biological and cultural reproductive subject. As long as teaching is that particular cognitive work in which the knowledge is hoarded to wield a lower power, women have been reduced to technical roles of teachers, so to be excluded from the spaces reserved to higher power: economy and politics. Maternalistic and consumerist structures typical of the last times led this subordination to a crisis in Italy too, but with no creation of a good alternative model. When the so-called First Republic (that was a kind of symbolic Father-State crashed down, the female model of cultural transmission broke up at the same time. In order to understand this trend, and perhaps to reverse it, the feminisation of teaching should be considered as a political question, and no longer as a treasure to be protected or defended. The same target regards the public school too.

    Full Text Available This article aims to analyze the relations between the trial of Adolf Eichmann and the Israeli national identity. It analyzes a trial which has its roots in the ius gentium and continues until the reappropriation of the memory of the Holocaust by Israel. The trial of Nazi criminal represents the moment when the Jewish state integrates his national experience to the memory of the destruction of European Jewry during the Second World War. Through the trials against Eichmann and its consequences on the Israeli public opinion, Ben Gurion strove for a nationalist rewriting of the Holocaust. The role of justice and law is central to the development of the national identity of Israel, providing a renewed civil identity that makes Israel the ‘guardian’ of memory and shifting the focus from the classic themes of Zionism.

    RIASSUNTO Introduzione I parametri di pressione arteriosa, sistolica (PAS) o diastolica (PAD) hanno costituito I’oggetto di numerosi studi, alcuni dei quali stabiliscono un’associazione tra I’aumnto di tali parametri e la mortalità, in particolare alle età medie. I fattori di rischio di ipertensione più frequentemente studiati sono il consumo di alcol, il fumo e I’origine etnica in riferimento sia alle differenze genetiche che nella condotta alimentare, mentre i fattori di origine professionale sono stati presi in considerazione più raramente e in maniera poco approfondita, inoltre sono state riferite notevoli differenze nelle pressioni arteriose medie di individui che svolgono professioni diverse. Sembra infatti che i “colletti blu” siano più a rischio dei “colletti bianchi”. Obiettivi Il nostro scopo è valutare se determinati rischi o vincoli connessi con l’attività professionale o determinati stili di vita rappresentano un fattore di rischio per l’ipertensione arteriosa in considerazioni dell’aumentare dell’età. Elementi specifici che rendano conto di questa relazione non sono stati ancora completamente chiariti e soprattutto i dati sulla popolazione italiana sono molto limitati. Metodi La metodologia di ricerca utilizzata è stata quella dell’indagine francese ESTEV (Derriennic, Touranchet, Volkoff) - VISAT (Marquie, Janson), studio epidemiologico longitudinale su oltre 23000 lavoratori attivata in Francia nel 1990 al fine di indagare gli effetti a lungo termine delle condizioni di lavoro, riferite all’intera vita professionale, sia sull’invecchiamento sia sulla salute dei lavoratori. Analoga indagine è stata avviata in Italia, nel 2000, in 6 Regioni, prendendo in esame i lavoratori dipendenti di diversi settori produttivi appartenenti a 5 coorti di età: da 32 a 52 anni con intervallo di 5 anni. Le rilevazioni sono state effettuate dai medici del lavoro di azienda attraverso 3 questionari: 1. sulle condizioni

    Full Text Available Il paesaggio è un’entità spaziale complessa, nella quale troviamo registrate, sedimentate nel tempo, le trasformazioni di genere naturale e culturale, espresse con un linguaggio universalmente comprensibile in un testo unico e fragile. A questa concezione matura del paesaggio si può riferire il suo riconoscimento come indicatore di sintesi dello stato dell’ambiente, che l’ex Agenzia nazionale per la protezione dell’ambiente proponeva sul finire degli anni Novanta, indicando pertanto una possibile via, non semplice, né esaustiva, ma chiara e praticabile, per l’analisi e il progetto della sostenibilità dello sviluppo territoriale. La stessa definizione olistica che la Convenzione europea attribuisce al paesaggio costituisce una conferma ed un rafforzamento del suo significato quale esito primario delle modalità di sviluppo territoriale e pertanto della sua valenza di termine di valutazione delle relative condizioni di sostenibilità.

  7. La città sotterranea e il suo ruolo nella mobilità urbana

    Full Text Available La città sotterranea è un elemento fondamentale nella struttura urbana. Soprattutto nelle grandi città essa assume connotazioni rilevanti nella pianificazione urbana in considerazione del fatto che rappresenta una risorsa e il suo impiego può incidere significativamente sull’efficienza del sistema urbano. Alcune città, a causa soprattutto della rigidità del clima, hanno progettato città sotterranee di grande complessità funzionale; esempi significativi sono Montreal, Toronto e altre città del Nord America. In Europa occidentale le realizzazioni associabili al concetto di città sotterranea sono più limitate e sono relative soprattutto alla realizzazione di infrastrutture per la mobilità urbana, come le reti metropolitane, i passanti ferroviari, i tunnel stradali e i parcheggi sotterranei. La funzione primaria di questi spazi è la riduzione e lo spostamento dalla superficie di quote di traffico e la trasformazione di ampie parti della città in aree verdi o in aree a maggiore qualità ambientale. In ogni modo è possibile sostenere che l’uso degli spazi sotterranei è ormai entrato a far parte della vita delle città moderne. L’articolo analizza alcuni dei fattori principali nella costruzione di questi spazi urbani; i costi e i benefici dell’uso di spazi sotterranei sono messi in relazione con gli aspetti psicologici e con la costruzione di modelli per la previsione dei percorsi degli utenti. La seconda parte dell’articolo mostra alcuni casi studio evidenziando le diverse necessità che hanno spinto e hanno guidato verso la scelta degli spazi sotterranei; una analisi più dettagliata è svolta sul caso di Montreal, che può essere considerato archetipo della citta sotterranea.

    One of the tendencies in many power reactors has been to modify some operation conditions, in order to increasing the electricity generation. The Laguna Verde Nuclear power plant (CNLV) it has not been the exception and in the recent past an increment of 5% was made in the original nominal thermal power. In the face of the possibility of carrying out more modifications, a study was made in the one that one simulates an eventual increment of the power of the reactor in 15% of the original value. With this increment one carries out the balance of the plant and the thermodynamic properties were determined. With this purpose it was developed a computer tool to calculate the thermodynamic properties of the plant in several points of the power cycle, as well as to carry out energy and mass balances to determine the flows in the different extractions of steam of the turbines. The program is compared with the results to 100% and 105% of increase of power obtaining good results, for what it is concluded that the extrapolation to 115% of power increase is acceptable.

    2006-07-01

    Full Text Available Los suelos con capa freática poco profunda poseen mayor probabilidad de ser afectados por anegamiento. La predicción de la oscilación temporal del nivel freático constituye una importante herramienta para valorar el riesgo de ocurrencia de tal proceso. El objetivo de este trabajo es presentar los fundamentos teóricos, la estructura operativa y la capacidad predictiva del modelo de simulación del balance hídrico Freat.1. El modelo se fundamenta en el cálculo de la transferencia de agua entre la atmósfera, el perfil del suelo, la vegetación y la capa freática. Los procesos de transferencia simulados son: escurrimiento superficial saliente, ascenso del nivel freático por efecto de la lluvia neta y del escurrimiento subterráneo entrante y descenso del nivel freático por efectos del escurrimiento subterráneo saliente, evaporación, ascenso capilar desde la capa freática y transpiración de la vegetación. Se evalúan los resultados de su aplicación en un Haplustol udorténtico y en un Natralbol típico ambos con freática oscilando a menos de tres metros de profundidad. El error de predicción estimado como la raíz del error cuadrático medio entre registros freáticos observados y simulados es menor de 15 cm para ambos suelos. Se concluye que el modelo resulta apropiado para predecir oscilaciones temporales de capa freática y evaluar el riesgo de inundación por anegamiento en suelos con capa freática cercana a la superficie.Soils with shallow water table have greater probability of being affected by waterlogging. The prediction of the water table depth temporal oscillation is an important tool to assess the risk of occurrence of such processes.

    Full Text Available Background: departments are the corner stone in teachers’ training. Considering teachers’ needs as a starting point, they should strengthen collaboration and teamwork with an institutional vision. Objective: to analyze the integrated working accord of teachers in the departments of the headquarters of the Faculty of Medical Sciences. Method: a development research was conducted including working accords of 163 teachers in 12 departments of the headquarters from November to January 2011. A questionnaire was conformed and applied to the heads of departments. It included: characterization, educational teaching work, methodology, research and professional training. Results: 93.8% of teachers have at least basic educational training, there are 64 teachers included in research projects (39.3% of faculty. In teaching-educative work we should continue to increase the amount of teachers incorporated to examining boards, tutoring scientific work and collaborating with students living in the schools’ residence. In methodological work we still do not achieve 100 % enrollment of teachers in the preparation of subject matters. Only 34.4 % of teachers conduct research on pedagogy and 55.2 % must publish the results of their scientific research. Conclusions: the balance of teachers’ working accord is a useful tool for the process directives management. It allows improving the department’s management and reorganing tasks that enhance professional development.Fundamento: el departamento constituye el eje vertebral en la formación del profesorado, a partir de necesidades, debe potenciar la colaboración y el trabajo en equipo desde una visión institucional.

    Obiettivo: misurare la quota di differenza sociale nella salute generata dall’accesso al sistema di cure, attraverso un follow-up dei pazienti ricoverati presso il principale ospedale di Torino.

    Metodi: tutti i primi ricoveri per infarto del miocardio (patologia acuta - AD e per tumori del coloretto (patologia cronica - CD dal 2000 al 2001 erano arruolabili. A questi è stato proposto un questionario sulle modalità di accesso ai servizi sanitari. È stata inoltre analizzata la cartella clinica per la valutazione degli interventi intra-ospedalieri. Indicatore di categoria sociale: titolo di studio.

    Risultati: analizzati 268 pazienti. Il 99% con AD ed il 97.5% di quelli con CD hanno aderito. Arruolati maggiormente uomini pensionati (circa 67%, condizione dovuta al tipo di patologia in studio. Sintomatologia di esordio: tipica della patologia infartuale e del colon-retto.

    Full Text Available Las mediciones registradas por los interruptores principales de ocho de los 50 circuitos de distribuciónprimaria de la ciudad de Santa Clara, muestran la existencia de un 29.8% de desbalance entre lascorrientes de fase y de un 51.5% de corriente de neutro como promedio. El desbalance entre las corrientesde fase provoca un incremento de las pérdidas energía en el circuito primario y contribuye al desbalancede los voltajes en los distintos nodos. Además, la circulación de una elevada corriente por el conductorneutro en condiciones de operación normal complica la detección de las fallas a tierra a partir deprotecciones de sobre corriente de neutro. El objetivo del presente trabajo es desarrollar un método quedetermine las mínimas operaciones de reconexión necesarias, de los ramales de una o dos fases y de losbancos y transformadores de distribución, que minimicen las pérdidas de energía en toda la longitud de uncircuito de distribución diversamente ramificado y que reduzcan la corriente de neutro a valoresaceptables. The measurements registered by the main breakers of eight of the 50 primary distribution circuits of SantaClara city, shown the presence of a 29.8% of phase currents unbalance and a 51.5% of neutral current asaverage. The phase current unbalance increases the energy losses in primary circuit and contributes to thevoltages unbalance on the different buses. On the other hand, the presence of a high neutral current onnormal operation difficult the detection of earth faults by neutral over current relays. The main purpose ofthis work is to develop a method that determines the minimal reconnection operations needed for the twoand single phase lateral feeders, as well as for the transformers banks and the single phase distributiontransformers, to minimize the energy losses on the primary distribution circuit and reduce the neutralcurrent to an accepted level.

    Full Text Available Enhancing cultural heritage in mountain regions is a crosscutting topic: environmental protection, social and cultural promotion and economic development have the same relevance and require to find a durable balance among them. Alpine areas bear geographic and permanent disadvantages. These include physical factors, such as morphology, climate, hydro-geologic risk, and human geography weaknesses, such as the low density, which prevents any arising of agglomeration economies, the isolation of local communities and the limited accessibility. Moreover, the opportunities for strengthen the territorial development by cultural heritage are not always consensual. Conflicts between preservation of tangible and intangible cultural values for local communities and the heritage marketing according to consumers’ needs often arise. This paper proposes an integrated approach able to consider the spatial features of each dimension of the problem and to support the definition of future development strategies. In particular, the proposed approach will be tested on a real case related to the system of historical castles located in the Valle d’Aosta Region in the North of Italy.

    Full Text Available Catalogare non vuol dire semplicemente costruire un catalogo. Vuol dire far sì che gli utenti accedano tempestivamente alle informazioni pertinenti alle loro esigenze. Il lavoro di identificazione delle risorse raccolte da biblioteche, archivi, musei, dà luogo a ricchi metadati che possono essere riutilizzati per molti scopi ("le attività dell’utente". Ciò comporta la descrizione delle risorse e il mostrare le loro relazioni con persone, famiglie, enti e altre risorse, consentendo così agli utenti di navigare attraverso surrogati delle risorse per ottenere più rapidamente le informazioni di cui hanno bisogno. I metadati costruiti lungo tutto il ciclo di vita di una risorsa sono particolarmente preziosi per molti tipi di utenti: dai creatori delle risorse, agli editori, alle agenzie, ai librai, agli aggregatori di risorse, ai fornitori di sistemi, alle biblioteche, ad altre istituzioni culturali ed agli utenti finali. Il nuovo codice internazionale di catalogazione, RDA: Resource Description e Access, è progettato per soddisfare le attività di base degli utenti producendo metadati ben formati e interconnessi per l'ambiente digitale, dando la possibilità alle biblioteche di rimanere rilevanti nel web semantico.

    Full Text Available Il tema affrontato concerne il ruolo dell’informazione economica nell’ambito dei mercati immobiliari. Si parte dai riferimenti della letteratura economica sulla teoria dell’informazione per individuare le informazioni economiche rilevanti per monitorare e analizzare il mercato immobiliare, sia dal punto di vista macroeconomico sia da quello microeconomico. In entrambi gli ambiti non è sufficiente soltanto l’informazione sul prezzo, ma su numerose altre variabili. Sull’importanza dell’informazione economica è utile l’indicatore della trasparenza dei mercati immobiliari elaborato da Jones Lang Lasalle costruito anche sulla base di una valutazione sulla qualità e quantità di informazione economica disponibile sugli oggetti scambiati sui fenomeni che caratterizzano il mercato immobiliare. Si analizza infine lo stato dell’informazione in Italia sul mercato immobiliare ed il ruolo e l’offerta informativa istituzionale resa dall’Osservatorio del mercato immobiliare dell’Agenzia del Territorio.

    Full Text Available El Programa Nacional de Bilingüismo colombiano busca mejorar el aprendizaje del inglés como lengua extranjera en los distintos niveles de la enseñanza. Hasta ahora se han realizado pocos estudios sistemáticos dentro de las escuelas que permitan conocer el estado real en que se encuentran en relación con ese Programa. En nuestra investigación, realizada en la ciudad de Santiago de Cali, se utilizaron encuestas, entrevistas y un examen internacional para dar cuenta de la gestión administrativa llevada a cabo por los directivos académicos y del nivel de inglés de los profesores, dentro de otros aspectos tendientes a definir el perfil de los docentes de inglés. Para la muestra participaron 56 instituciones que representan las 22 comunas en que está dividida administrativamente la ciudad y se ubican en estratos socioeconómicos bajos y medios. Se encontró una gestión de los recursos y del talento humano insuficiente para apoyar los procesos de implementación de la política educativa; además, los niveles de lengua de los profesores están, generalmente, por debajo de las metas del PNB, que busca que en el año 2019 los docentes en ejercicio tengan un nivel de usuario intermedio (B2 de acuerdo con MCER. Adicionalmente, se registró una brecha entre la enseñanza privada y pública del inglés, que va en contravía con el espíritu de la política educativa. Estos hallazgos sugieren que existe la necesidad apremiante de revisar en contextos escolares particulares las condiciones en que se da la enseñanza de la lengua extranjera para tomar acciones que redunden en su mejora si se aspira a mejorar los niveles de competencia en inglés de los estudiantes.

    Full Text Available The work tackles the development of a procedure to evaluate the energetic efficiency in linear infrastructures from a constructive point of view. This procedure allows to calculate the balance of energy along the different phases of life cycle analysis in infrastructure, such as construction, operation - maintenance and deconstruction, both in general and independent terms. Being the target the quantification of energy in the infrastructure, the procedure allows the efficient management of its energy consumption and other environmental impacts, throughout the selection of alternatives and the mitigation or compensation of the balance between its different phases. This paper describes the developed methodology in the procedure, tested by means of a practical example case study, where the embodied energy of one of the functional units in which the motorway is divided (a straight two-way highway stretch is quantified in Jules. The individual amount of different phases is also quantified to establish a balance between them too

    Complex chromosomal rearrangements (CCRs) are structural aberrations involving more than two chromosomes which rarely appear in individuals with normal phenotypes. These individuals report fertility problems, recurrent miscarriages, or congenital anomalies in newborn offspring as a consequence of either meiotic failure or imbalanced chromosome segregation. A CCR involving chromosomes 5, 15, and 18 was discovered in a phenotypically normal man through a fetus with congenital malformations and partial trisomy of chromosome 15 and monosomy of chromosome 5. Ultrasound examination at 20 weeks of gestation showed severe oligoamnios and hydrothorax. Prenatal cytogenetic analysis and array comparative genomic hybridization (array-CGH) revealed a female fetus with dup15q26.3 and del5p15.33. We diagnosed the CCR using three-color fluorescence in situ hybridization (three-color FISH), and a balanced CCR using array-CGH and FISH was diagnosed in the paternal karyotype. The father is a carrier of a balanced translocation 46,XY,t(5;15;18)(p15.31;q26.3;p11.2). Due to the complexity of these rearrangements the diagnosis is difficult and the reproductive outcome uncertain. Reporting such rare cases is important to enable such information to be used for genetic counseling in similar situations and help estimate the risk of miscarriage or of newborns with congenital abnormalities.

    Full Text Available The demographic flow linking Latin America and Spain has not only consolidated during the last decades of the 20th Century, but it has changed as regards its composition. This article aims at showing that immigrants are fewer than is thought, and that their distribution in the Peninsula and the Islands is not homogeneous. Statistical sources prove that they lie behind the immigrationcommunities coming from Morocco and Europe. However, they are directly affected by the legal restrictions to the entrance of foreigners, for which reason they have developed new strategies to attain a legalized situation.

    La corriente demográfica que une Lartinoamérica con España no sólo se ha ido consolidando en las últimas décadas del siglo XX, sino que ha cambiado su composición. Este artículo pretende demostrar que los inmigrantes oriundos de ese área, ni son tantos, ni se han distribuido homogéneamente por toda la geografía peninsular e insular, ya que las fuentes estadísticas los ubican por detrás de los marroquíes y de distintos colectivos de la Europa comunitaria. Sin embargo, las restricciones a la entrada de extranjeros los afectan por igual, con lo cual han ido desarrollando nuevas estrategias para acceder a la condición de regulares.

    Full Text Available Los humedales de San Pedro sostienen redes tróficas del sistema fluvial debido a la alta disponibilidad de hábitats y a sus variaciones espacio-temporales. En esta investigación se estudió la composición, densidad y biomasa de la ictiofauna de los humedales; se capturaron 1 049 organismos de 25 especies, dos son exóticas: Oreochromis niloticus y Parachromis managuense. Con 23 especies capturadas en el sitio I, 17 en el II y 14 en el III. En la época de secas se obtuvo mayor riqueza con 21 especies, lluvias con 17 y cinco en nortes. La mayor densidad se mostró en el sitio II (0.23ind./m², seguido de los sitios I y III (0.12, 0.12ind./m². La mayor biomasa fue en secas (8.30g/m², seguida de lluvias (2.1g/m² y por último nortes (0.01g/m². La mayor densidad se mostró en secas (0.43ind./m² y la mínima en nortes (0.023ind./m². Las especies dominantes en densidad según el diagrama Olmstead-Tukey fueron: Petenia splendida, Vieja heterospila, Vieja synspila, Dorosoma petenense y Astyanax aeneus. Por lo tanto, existieron diferencias significativas en los parámetros ecológicos y ambientales. Al considerar la variación en la riqueza podemos concluir que los humedales del río San Pedro, es un sistema donde la composición de la ictiofauna responde a las fluctuaciones espaciales y temporales.

    Full Text Available Este artículo analiza la transformación del estado nacional colombiano bajo el gobierno de Álvaro Uribe, centrándose en el Plan Colombia y los proyectos estatales que se desprenden de él, a fin de dar cuenta de la militarización estatal y la represión social asociada a ambos. Se argumenta que políticas de gobierno amparadas en dicho Plan tienen como objetivo la consolidación de un régimen de acumulación de mercado extractivo y especulativo que, aunque vinculado a un impulso hegemónico transnacional centrado en los Estados Unidos, también está íntimamente ligado a desarrollos locales y al conflicto interno de Colombia. Estas interacciones ofrecen una ilustración ejemplar de la reconfiguración a múltiples escalas de la política en la economía del mundo actual.This article analyzes the transformation of the Colombian national State under the government of Álvaro Uribe, focusing on Plan Colombia and the State projects that flow from it, in order to reflect on the militarization of state and the social repression associated with both. It is argued that government policies under the Plan are aimed at consolidating a regime of market accumulation and speculation that, while linked to a transnational hegemonic thrust emanating from the United States, is also closely linked to local developments and Colombia's internal conflict. These interactions provide an exemplary illustration of the reconfiguration at multiple levels of the world political economy today.

    Full Text Available Il saggio poggia su di una ricerca etnografica condotta alla Centrale di Ascolto e nell'Area medico legale del Tribunale per i Diritti del Malato le cui attività hanno una forte dimensione narrativa dato che raccoglie le storie dei cittadini su presunti errori medici, fornendo un parere medico-legale sull'eventualità di avviare un'azione per ottenere il risarcimento del danno subito. Ogni narrazione è dialogica, si colloca all'interno di una relazione comunicativa che coinvolge chi narra e chi ascolta. Nel nostro caso è il consulente del Tribunale che adotta la postura professionale del destinatario, che da senso al racconto del cittadino deluso, arrabbiato e disperato. Ai suoi occhi, è un terapeuta, uno story taker che stimola e accoglie una storia segnata da un evento drammatico, ove il ruolo del nemico è attribuito al medico negligente e arrogante.

Design/methodology/approach: Hypotheses were tested using data obtained from a questionnaire sent to 591 public organizations and 549 private organizations in Portugal, with an overall response rate of 31.3%. Findings and Originality/value: The results indicate the association between BSC knowledge and the level of training of employees, and between BSC implementation and conducting training courses. On the other hand, we did not obtain empirical evidence regarding the possible relationship between the BSC implementation and the degree of internal communication, the use of external consultants, questions of "management fads" and the search for legitimacy. Originality/value: In the literature review we did not found bibliographic elements about the contingent and institutional factors that determine the BSC adoption in Portugal, a fact that allowed us to give this study an innovative approach. Moreover, the BSC situation in Portugal has been characterized, doing a comparative study with the results of studies conducted in other countries.Objeto: Este artículo tiene como objetivo identificar y analizar un conjunto de variables contingentes e institucionales que pueden potencialmente influir en el conocimiento e implementación del Cuadro de Mando Integral (CMI en las organizaciones portuguesas pertenecientes al sector público y privado.

    Il libro mostra come la gravitazione abbia un ruolo determinante nei fenomeni cosmici che più ci impressionano, da quelli relativamente vicini alla nostra esperienza (come la formazione delle stelle) a quelli meno intuibili (come la formazione dei buchi neri), alla struttura dell'Universo nel suo insieme. Oltre a spiegare, in modo qualitativo, concetti come la geometria dello spazio-tempo, la relatività del tempo e i coni di luce, l'autore formula un'ipotesi innovativa tendente a spiegare l'origine della gravitazione e con essa quella dei fenomeni circondati ancora da un alone di mistero: la materia oscura dell'Universo e il destino della materia alla fine del collasso gravitazionale.

    The aim of the present work is to assess the hydro-geological water balance of the soil and subsoil system. At the beginning, the natural groundwater recharge evaluated as the subtraction between the soil inflows (rainfall) and outflows (evapotranspiration, surface runoff) enable to determine the soil water balance. Then, in order to calculate the subsoil water balance, the withdrawals for different purposes have been estimated together with the inflows coming from other water bodies and the coastal outflows. This method has been applied through a GIS technique; in particular, after the data layers acquisition (climatic, topographic, geologic, land use, satellite images, etc.), the numerical calculation has been done and several thematic output maps have been obtained. The method has been applied to the whole Apulian region; in this work, only the results about Salento Peninsula have been reported. The results highlight a significant water resources deficit; this deficit is also confirmed by the deepening of groundwater piezometric heads and the increase of chlorine ions, measured, for more than 10 years, in some characteristic points located in the study area. [Italian] Scopo del presente lavoro e' valutare il bilancio idrogeologico mediante il bilancio di massa per il sistema rappresentato dal complesso suolo e sottosuolo. Inizialmente e' stato valutato il bilancio idrico del suolo che ha consentito di determinare la ricarica naturale della falda per differenza tra gli ingressi al sistema suolo (apporti meteorici) e le uscite dal suolo agrario e dalle colture (evapotraspirazione), ed il deflusso superficiale. Successivamente, per calcolare il bilancio di massa del sistema sottosuolo sono stati stimati gli emungimenti per i diversi usi, gli afflussi provenienti da altri corpi idrici sotterranei e gli efflussi a mare. La metodologia e' stata implementata utilizzando una tecnologia GIS; in particolare, dopo l'acquisizione dei diversi strati

Estendere l’esperienza albanese agli altri Stati balcanici o quella dei Balcani all’Albania? Abstract   The protection of individual and collective freedom of religion and freedom of conscience, the regulation of state relations with religious communities in Albania, have found a solution in peculiar legal rules and traditions that in the history of the Albanian people have guaranteed the religious peace. Of great significance was the Albanian legal system resistance to accept the advice of the Venice Commission, Council of Europe and the EU that would rather prefer and have sought to impose the adoption of a single political-legal model for the Balkans, focused on a general law for the protection of religious freedom.Albanian model dates back to 1923, recognizes the cultural and religious pluralism of society and the opportunity for all religious communities to obtain civil legal personality, now allows cooperation agreements with the various religious communities. The rules put as guarantees of religious freedom those of the general law without any recourse to special rules. What happened was possible because of the plural nature of Balkan Islam which has allowed mutual respect and tolerance, and thanks to the secular and separatist nature of the Albanian state since its origins.State law likewise religious rules, determined by the Statutes that communities have been given themselves and their progressive transformation have played a role in education for coexistence which has allowed, in contrast to what happened in many Balkan countries, religious peace.The smaller denominations and cults have found, and find now, legal protection, and at present are five the creeds that have concluded agreements with the state and others may do so in the future. The success of the Albanian model warns against standardization policies, substantially octroyé, supported by international bodies end one size fits all legal model/pattern.

    Full Text Available The introduction of low molecular weight heparins (LMWHs has opened new possibilities for the costeffective management of the thrombotic risk associated with surgical procedures, allowing prophylaxis – and sometimes even treatment of established deep vein thrombosis – on a out-patient basis. This article gives a brief overview of the pharmacological and clinical features of LMWHs, focusing on the differences with unfractionated heparin (UFH, which allow great simplification of dosing regimens and settings without disadvantages in terms of efficacy or safety. In fact, some data indicate that LMWH might be better tolerated than UFH. The overcoming of the need for hospitalization for pre- and post-surgical thromboprophylaxis has important economical implications and is leading to a different formation of health care costs in these patients. The clinical and economical consequences of the pharmacological differences between LMWHs and UFH are analyzed with a “value matrix”, a pharmacoeconomical technique for preliminary evaluations. The last section examines Italian drug acquisition costs and compares the economical values of the recommended dosing regimens of LMWHs available on the national market for the prevention and the treatment of deep vein thrombosis. Bemiparin is the most convenient LMWH for all approved indications. In the management of surgery-associated thrombotic risk, no clinically relevant differences among LMWHs have been demonstrated. Thus, bemiparin appears to be the most logical choice in a costminimization strategy.

    Obiettivi: l’associazione fra stato socio-economico (SES ed attività fisica è poco indagata. Obiettivo del presente studio è quello di valutare la relazione tra attività fisica extra-scolastica di adolescenti scolarizzati e lo SES della famiglia di provenienza.

    Metodi: l’indagine ha previsto la somministrazione nel corso dell’anno scolastico 2002-2003 di un apposito questionario anonimo autocompilato, già validato in uno studio pilota, ad un campione di studenti delle scuole medie inferiori del Lazio (province di Roma, Frosinone e Latina.

    Risultati: hanno partecipato allo studio 1486 studenti di cui 756 maschi (50.9% e 730 femmine (49.1%. L’età dei partecipanti varia fra gli 11 ed i 15 anni (età mediana 12 anni. Il 72.7% degli studenti dichiara di svolgere attività fisica al di fuori della scuola. Il livello di istruzione dei genitori e la loro attività lavorativa sembrano avere un peso notevole sui determinanti dell’attività fisica negli studenti. Infatti, svolgono prevalentemente attività fisica extra-scolastica i figli di genitori manager/libero professionisti (OR = 3.29 e con un elevato livello educativo (OR = 10.38 per i figli di genitori laureati.

    Conclusioni: i risultati confermano quanto la situazione socio-economica delle famiglie sia in netta relazione con l’attività fisico-sportiva dei giovani. Tali risultati potranno essere utili per gli operatori scolastici e gli amministratori nell’ispirare e realizzare azioni volte a diminuire il divario esistente fra i giovani che hanno le possibilità economiche e svolgono attività sportiva extra-scolastica e quelli che, invece, appartenendo a famiglie svantaggiate, hanno minore accesso a tali attività.

Sono stati rivalutati rispettivamente 11 pazienti (7 maschi e 4 femmine; eta' compresa tra 33 e 87 anni, media 64 anni) affetti da spondilodiscite spontanea osservati nel periodo 1994/99. Sono stati esclusi volutamente i pazienti con spondilodiscite imputabile a recente intervento chirurgico per ernia discale lombare. La RM e' stata condotta con un apparecchio da 1, 5 Tesla utilizzando sequenze TS pesata in DP e T2 e SE pesata in T1 sul piano sagittale, TSE in DP e T2 sul piano assiale per il segmento lombare, GRE pesata in T2 sul piano assiale per il segmento lombare, GRE pesata in T2 sul piano assiale per i segmenti cervicale e dorsale e SE pesata in T1 sui piani assiali dopo somministrazione di gadolinio. La revisione delle immagini cosi' ottenute ha riguardato le alterazioni morfologiche e del segnale del disco intersomatico e dei corpi vertebrali adiacenti interessati dal processo infettivo. In 9 pazienti e' stato possibile confrontare i reperti di RM con quelli di TC eseguita nei giorni immediatamente precedenti. In 3 pazienti erano presenti processi infettivi in altri organi e 2 erano diabetici. Solo in due casi e' stato eseguito l'esame batteriologico su biopsia discale che ha riscontrato la presenza di Stafilococcus aureus in uno e di Micobacterium tubercolosis nell'altro. In tutti i casi la RM ha permesso la diagnosi corretta dimostrando con precisione e piu' precisamente rispetto alla TC l'estensione del processo patologico nei tessuti molli paravertebrali e/o nel canale spinale

Fra i tanti motivi di estremo interesse qui presenti segnaliamo la riflessione sul ruolo degli animali in letteratura in riferimento al tema flaubertiano della bêtise – con aperture teoriche che troveranno ampie conferme negli studi letterari degli anni più recenti – e, ad essa legato, l’insistito richiamo sulla «possibilità di una visione del mondo completamente diversa», che ammetta la «curvatura» dello spazio e del tempo, quale presupposto della parola romanzesca.

Among the advantages are the composition and visualization of performance measurements that reflect the company’s business strategy. The BSC summarizes and indicates in a single document, performance from four perspectives, financial, clients, internal processes and learning and growth. This study is important because the BSC is the first systematic attempt to develop a project for a performance evaluation process that focuses on company objectives, coordination of individual decisions and a basis for the organizational learning. Therefore, applicable literature was reviewed and a presentation was made on implementation of the BSC at Petrobras, an integrated state-owned company acting in exploration, production, refining, commercialization and transport of oil and derivatives in Brazil and abroad.El Balanced Scorecard (BSC, desarrollado por Kaplan y Norton en 1992, resultó de la necesidad de captar toda la complejidad del desempeño de la organización, y ha sido amplia y creciente su utilización en empresas y organizaciones.

    Para tratar de cumplir este propósito he escogido dividirla en dos partes:

    1 La presentación y discusión de un modelo curricular que parezca adecuado para un pais como Colombia;

    2 Un planteamiento reflexivo sobre el estado actual de la educación medica frente al acelerado desarrollo tecnológico y cientifico que ha caracterizado a la segunda
    mit ad del siglo XX.

    El punto de partida, al abordar el tema de la formación del medico general integral, ciertamente es un plan de estudios que ponga al alumno en contacto con la realidad del medio, que estimule su inquietud intelectual, que le inculque sólidos habitos de estudio, en ambientes y escenarios educacionales donde el rigor cientffico y la disponibilidad de avanzaa tecnología constituyan Ia disciplina intelectual y el medio natural, dentro del marco de una elevada concepcion de ética profesional y social, y que le cree, por lo menos, una actitud positiva y una disposición hacia la invcstigación científica...

    Full Text Available Objetivo: Examinar la relación entre el perfil de los directivos y el uso del cuadro de mando integral y del presupuesto en la consecución de objetivos estratégicos centrados en la reducción del coste y en la mejora de la flexibilidad en la prestación de servicios sanitarios. Métodos: Los datos se recogieron mediante una encuesta enviada a 884 directivos miembros de equipos de dirección de 218 hospitales públicos en España. El índice de respuesta fue del 53,51%, con 473 cuestionarios útiles. Se realizó una validación métrica de las escalas usadas y un análisis del modelo con técnicas de ecuaciones estructurales. Resultados: Los directores más jóvenes y con menos antigüedad suelen hacer un mayor uso del cuadro de mando integral que del presupuesto. La diversidad en el equipo de dirección está relacionada con el empleo de diferentes técnicas de control de gestión. El uso del cuadro de mando integral se relaciona positivamente con la implantación de estrategias sanitarias centradas tanto en la mejora de la flexibilidad como en el control y la reducción del coste sanitario. Conclusiones: La adopción de sistemas de control de gestión no sólo es resultado de un proceso racional y de presiones institucionales, sino que también depende de las características de los individuos responsables de la toma de decisiones. El uso del cuadro de mando integral facilitará que los hospitales puedan implantar planes estratégicos con múltiples objetivos.Objective: To analyze the relationship between hospital managers' characteristics and the use of the balanced scorecard and the budget.

    Full Text Available La influencia de la vegetación (Heliconia psittacorum y el principal mecanismo de eliminación de nitrógeno en un humedal construido de flujo subsuperficial (HFSS fueron estudiados por la aplicación de un balance de N. Para ésto se construyeron seis unidades de HFSS a escala de laboratorio (microcosmos que incluyeron lechos de grava plantados con Heliconia sp. y sin plantar (controles, sometidos a una carga de 5,68 g N m-2 d-1 y un tiempo nominal de retención de 1,0 día. Los resultados indicaron una mayor eficiencia de eliminación de la carga de N en los microcosmos plantados (29,6% comparado con los sin plantar (24,3%. El balance de masas indicó que el principal mecanismo de eliminación de N fue la nitrificación/desnitrificación al eliminar el 66,7 y 69,7% del N eliminado en los microcosmos plantados y sin plantar, respectivamente. La acumulación en el medio de soporte eliminó el 21,4 y 22,0% del N, respectivamente. Mientras que una pequeña asimilación del N por la Heliconia sp. fue establecida (0,6%. Pese a la baja asimilación directa de N por parte de la planta, fue evidente que éstas contribuyeron indirectamente a la eliminación de N en los microcosmos plantados vía la translocación de oxígeno atmosférico y el ensamblaje de una comunidad microbiana más diversa en la rizósfera.

    oesophageal perforation, CT showed the presence of a intramural haematoma in one case, oesophageal fluid distension with gas and a small peri-oesophageal fluid effusion (Mallory-Weiss syndrome) in another, and oesophageal rapture (Boerhaave syndrome) in the last case. Conclusions: Our experience shows that in patients with suspected traumatic and spontaneous oesophageal perforation, standard cervical and chest radiography may suggest a suspected oesophageal perforation in only a small proportion of cases, whereas oral contrast oesophagography has a higher sensitivity. Through the careful analysis of suggestive and specific signs of oesophageal perforation, a correct CT examination enables an accurate and timely diagnosis which significantly affects prognosis and provides valuable indications for treatment. [Italian] Scopo: Presentare la nostra esperienza relativa al ruolo della TC nello studio delle perforazioni traumatiche e spontanee dell'esofago. Materiale e metodi: Da marzo 2001 a maggio 2003 sono giunti alla nostra osservazione 12 pazienti (7 di sesso maschile, 5 di sesso femminile, di eta' compresa tra 25 e 66 anni, eta' media 43,5) con sospetta lesione esofagea da incidente stradale (in 4 casi), ferita d'arma bianca (un caso), post-intubazione (2 casi), da indigestione di corpo estraneo (2 casi) e di tipo spontaneo (3 casi). Cinque pazienti praticavano l'esame standard del torace e della regione cervicale. In 2 pazienti con sospetta indigestione di corpo estraneo veniva somministrato gastrografin per os. In tutti i 12 casi veniva eseguito l'esame TC del collo-torace-addome senza e con mdc ev e con mdc idrosolubile per os in 4 casi. Risultati: Nei 5 pazienti con trauma cervico-toracico-addominale l'indagine TC evidenziava oltre a lesioni traumatiche pleuro-parenchimali (pneumotorace, versamento pleurico ed enfisema sottocutaneo) anche reperti suggestivi di perforazione esofagea: aria mediastinica in sede periesofagea (5 casi), fluido

    Full Text Available Dopo il provvedimento apripista del giudice pistoiese (commentato pochi mesi fa da Enza Pellecchia in questa rivista, le omologazioni del “piano del consumatore” sovraindebitato cominciano a moltiplicarsi: ancora il Trib Pistoia 8 gennaio 2014 e poi Trib.

Al di là delle differenti vicende da cui scaturiscono, le decisioni citate confermano tutte, più o meno marcatamente, l’impressione a caldo che avevamo tratto già all’indomani della tormentata approvazione della l. n. 3, e cioè che il congegno esdebitatorio di nuovo conio fosse destinato inevitabilmente a caricarsi di un ruolo di supplenza della scarna ed inefficace disciplina in materia di prevenzione del sovraindebitamento, sub specie di doveri informativi e verifica del merito creditizio (artt. 124 ss. t.u.b., offrendosi quale sede elettiva per reagire ex post alla condotta scorretta o anche solo disinvolta dei finanziatori professionali.

    The present work is a continuation of the task: Modeling of the vapor cycle of Laguna Verde with the PEPSE code to conditions of thermal power licensed at present (2027 MWt) in which the modeling of the vapor cycle of the nuclear power plant of Laguna Verde was realized with PEPSE code (Performance Evaluation of Power System Efficiencies). Once reached the conditions of nominal operation of extended power increase, operating both units to 2371 MWt; after the tests phase of starting-up and operation is necessary to carry out a verification of the proposed design of the vapor cycle for the new operation conditions. All this, having in consideration that the vapor cycle designer only knows the detail of the prospective performance of the main turbine, for all the other components (for example pumps, heat inter changers, valves, reactor, humidity separators and re-heaters, condensers, etc.) makes generic suppositions based on engineering judgment. This way carries out the calculations of thermal balance to determine the guaranteed gross power. The purpose of the present work is to comment the detail of the validation carried out of the specific thermal balance (thermal kit) of the nuclear power plant, making use of the design characteristics of the different components that conform the vapor cycle.

    Full Text Available  Il PTCP nasce nel clima della pianificazione europea rivolta alla realizzazione della rete TenT e della ricerca di come questo sistema di connessione potesse diventare strumento di sviluppo e coesione territoriale. Nella stessa scia si colloca tanto il Quadro Strategico Nazionale che il Piano Strategico Ragionale nei quali si definisce il ruolo territoriale della metropoli napoletana nel contesto internazionale. Queste premesse forniscono utili indicazioni per determinare l’organizzazione generale del territorio napoletano sia perché determinano nuovi ingressi da attrezzare adeguatamente al ruolo di vetrine e di accoglienza, sia perché contribuiscono a realizzare il sistema policentrico locale e le connessioni nel sistema delle centralità regionali. Tra i problemi di maggior delicatezza che si pongono c’è l’equilibrio tra vecchie e nuove centralità, ovvero la scelta se procedere secondo uno sviluppo additivo al sistema urbano esistente con il rispetto del patrimonio culturale e delle radici storiche. L’altro fondamentale termine di confronto è costituito dalle esigenze ambientali affermate prioritariamente con la difesa delle aree agricole e degli spazi aperti, ma di cui non si possono trascurare altre implicazioni quali quelle della capacità di un sistema urbano concentrato di rafforzare la competitività della mobilità verde.

    2017-03-01

    Full Text Available This article examines the tension among the anonymity of the gamete donor and the right of the child to know his origin, following the latest trend of the European legal systems. The analysis of legal systems that recognize such a right to children conceived through donated gametes allows us to think further on the hypotheses, now more extended, which consider that traditional arguments for secrecy are out-dated. In this regard, the article also challenges the different treatment granted to adopted children and donor gamete children by legal systems such as the Spanish one. Beyond the possible conflicting rights of children, donors and parents, arguments provided by anonymity supporters, such as moral damages resulting from disclosure or the possible link between disclosure and the decrease in the number of donors, should be also taken into account. However, these arguments require absolute empirical evidence which is not currently conclusive. Alternatively, disclosure of the identity of the donor, once the child has reached enough maturity, is seen as a solution to be studied in detail, as long as it does not lead to the establishment of parentage links. The article suggests that this solution is consistent with the needs of donor families, and with a major trend in family law supporting the right to know one’s genetic origin, dissociated from biological and legal parentage spheres. El trabajo plantea la compatibilidad entre la garantía de anonimato del donante de gametos y el derecho del nacido a conocer sus orígenes. A partir del análisis de los ordenamientos que reconocen este derecho a las personas concebidas mediante gametos donados, el trabajo pretende profundizar en las hipótesis, cada vez más extendidas, que consideran que las fundamentaciones tradicionales para mantener el secreto han perdido valor y, a su vez, indagar en si está justificado el diferente trato que en esta materia dispensan, al concebido mediante gametos donados

    Full Text Available Tra le figure più importanti del dibattito filosofico italiano del Novecento, Antonio Banfi ha svolto nell'Italia del secondo dopoguerra anche un ruolo politico di rilievo come senatore del PCI. La sua interpretazione del marxismo ha presentato una forte accentuazione umanistica. Tra i suoi scolari filosofi e storici della filosofia come Giulio Preti, Enzo Paci, Remo Cantoni, Paolo Rossi. Il saggio prende in esame la prima fase della riflessione filosofica di Banfi, nella quale ha una importanza decisiva la conoscenza diretta del dibattito tedesco tra le due guerre mondiali, in primo luogo della fenomenologia di Husserl e della ontologia di N. Hartmann. I Principi di una teoria della ragione - libro apparso alla fine degli anni '20 - e poi una serie di incisivi saggi degli anni '30 documentano una conoscenza approfondita e critica di un dibattito di cui mostrerà di nutrirsi in misura decisiva l'interpretazione di Banfi non solo di Hegel, ma anche di Marx.

    Full Text Available En el transcurso de los últimos 15 años, los gobiernos de los Estados Unidos y Colombia han trabajado conjuntamente para luchar contra el problema de seguridad más importante que ha enfrentado el continente americano en las postrimerías del siglo XXI. Los grupos Narco terroristas colombianos se convirtieron en la principal amenaza para la seguridad nacional de los Estados Unidos en el hemisferio occidental; no sólo a causa de la producción de drogas y el tráfico de drogas, sino también de las actividades terroristas en contra de los intereses de los Estados Unidos en la región. El Plan Colombia fue una estrategia que tuvo como propósito principal establecer y garantizar un Estado que pudiera ejercer su verdadera autoridad y cumplir con sus obligaciones esenciales. De igual forma, este plan tuvo un componente militar con el fin de poner fin al comercio de drogas mediante la erradicación de cultivos ilícitos. Algunos objetivos del Plan Colombia como reducir el cultivo, procesamiento y distribución de narcóticos ilegales atacando el cultivo de coca no se cumplieron, además, durante estos años el fenómeno de la minería ilegal comenzó a prosperar y se convirtió en una importante fuente de ingresos para los grupos narcoterroristas colombianos. Dentro de los Principales logros se puede establecer que con esta estrategia el Estado Colombiano ha logrado la recuperación de su institucionalidad y la consolidación de la presencia del gobierno en todas las áreas del territorio nacional, así como la reestructuración del sistemas políticos y jurídicos, el fortalecimiento de su economía, la profesionalización de las Fuerzas Armadas y la posibilidad de iniciar un proceso de negociación con las Fuerzas Armadas Revolucionarias de Colombia (FARC y el Ejército de Liberación Nacional (ELN.

    Full Text Available En este artículo los autores exponen el proceso vivido por la sociología para su profesionalizacióncomo programa académico en la Universidad de Antioquia desde 1968. Se señala como planteamiento central que la reflexión y comprensión sobre las disciplinas sociales en Colombia ha descuidado el estudio del papel cumplido por las universidades regionales, lo cual ha impedido tener una visión más equilibrada y exacta de la evolución de la disciplina sociológica en Colombia. El texto brinda una panorámica sobre las distintas etapas y dificultades ocurridas en el programa de sociología de la Universidad de Antioquia, destacando las discusiones y reflexiones desarrolladas por los docentes y estudiantes en torno a la definición de los contenidos curriculares y la orientación y características que debían darse al plan de estudios, en especial, se muestra el debate generado a lo largo de estos cuarenta años entre una sociología empírica y una sociología teórica y, la necesidad de mantener diferentes enfoques paradigmáticos que debían cruzar el plan de estudios para orientar la comprensión de la realidad social colombiana.En general, este artículo señala la importancia, que para la sociología como disciplina académica, ha tenido el impulso del componente investigativo como uno de los elementos centrales de la formación sociológica, el cual junto con una rigurosa fundamentación teórica garantiza la formación de un sociólogo íntegro y comprometido con los problemas del país.

El análisis se realizó utilizando los criterios propuestos por el sistema GRADE (Grading of Recommendations Assessment, Development and Evaluation. Se realizó una búsqueda de la literatura en Medline y en otras fuentes de información nacional (literatura gris. Para el desarrollo de la recomendación, a favor o en contra del tamizaje, se utilizó la mejor evidencia disponible sobre los beneficios, riesgos, costos y preferencias de la población. Los resultados incluyeron cinco revisiones sistemáticas (RS que evaluaron los riesgos y beneficios del tamizaje; dos evaluaciones económicas realizadas en Perú y un estudio que valoró indirectamente las preferencias de las mujeres peruanas. La calidad de la evidencia a partir de las RS fue moderada a favor del tamizaje en mujeres de 50 a 69 años. El balance entre riesgos y beneficios mostró una mayor probabilidad de sobrediagnóstico comparado con el beneficio en la reducción de la mortalidad. La estrategia más costo- efectiva fue la mamografía trienal. La percepción de barreras podría comprometer seriamente la participación de las mujeres. En conclusión, la recomendación a favor del tamizaje mamográfico en Perú es débil, más aun si se tienen en cuenta otras necesidades poblacionales más urgentes. En caso de llevarse a cabo, la estrategia de tamizaje más adecuada para la población peruana consistiría en realizar una mamografía trienal en mujeres de 50 a 69 años.

    In the risk evaluation of uncontrolled biogas emissions from landfills, the process of natural attenuation in landfill covers assumes a very important role. The capacity of biogas oxidation in the cover soils seems to be the most important control to mitigate the biogas emission during the aftercare period when the biogas collection system might fail. In the present paper laboratory experiences on lab columns to study the biogas oxidation are discussed. [Italian] Nella valutazione del pericolo di emissioni incontrollate di biogas da una discarica, il processo dell'attenuazione naturale della copertura superficiale assume un ruolo molto importante. La capacita' di ossidazione del biogas nel terreno di copertura sembra rappresentare il controllo piu' importante nella mitigazione di fughe incontrollate di biogas, soprattutto nel lungo periodo quando la captazione del biogas perde efficienza. Nel presente lavoro si riportano alcune esperienze di laboratorio per valutare l'ossidazione di metano in diverse tipologie di copertura.

Mediante un análisis de la evolución de los flujos de capitales y del comercio, y de su impacto sobre el empleo y el nivel de los salarios en los sectores industriales y agrícolas, el autor revela los logros y los límites del modelo de integración del TLCAN. Concluye que aunque el TLCAN no puede ser la solución a todos los problemas socioeconómicos de México, lo que el acuerdo padece, a pesar de todo, es una "institucionalidad (social deficiente" que puede consolidarse por medio de reformas nacionales y supranacionales. A nivel nacional, el gobierno mexicano tiene que replantearse su estrategia de crecimiento dependiente de las exportaciones y dar prioridad a la reforma fiscal y a las inversiones en el sector de la educación y las infraestructuras. A nivel supranacional, el modelo del TLCAN debería mejorarse con el fin de subsanar sus carencias sociales, particularmente en los sectores de la inversión, la inmigración, la agricultura y las transferencias de recursos.

    Full Text Available Hace dos años publiqué un Working Paper en esta misma colección de Estudios/Working Papers del GIGAPP: "La Administración que se espera para después de la crisis" (WP-2011-02. La intención de ese documento era vaticinar el impacto de la aguda y prolongada crisis económica sobre las administraciones públicas en España. Han trascurrido dos años desde que presenté esas reflexiones, y este paper tiene como misión destacar y reflexionar sobre lo que ya ha sucedido. Se trata de un análisis parcial elaborado al calor de los sucesos y, por tanto, carece de la consistencia del estudio académico elaborado con una más amplia perspectiva que solo permite el reposo que concede el tiempo. La primera conclusión es que, lamentablemente, las hipótesis incluidas en el paper previo se van cumpliendo en términos generales aunque con algunos matices que hay que destacar a modo de balance parcial. Frente a la profunda crisis económica, las crisis política, social e institucional han llegado para acompañarnos durante muchísimo tiempo. Como eje de las propuestas se seleccionan cinco temas críticos para la renovación institucional y la modernización de las administraciones públicas: a renovar los procesos de selección de los empleados públicos para preservar los principios de igualdad, capacidad y mérito y el resto de las grandes propuestas las comento de forma sintética como apostillas; b un estatuto de la dirección pública profesional; c transparencia; d un reenfoque de las tecnologías de la información; e mejorar los sistemas de gobernanza de los partenariados público- privados. Al final del documento se ubica un listado con todos los ítems, algunos de gran calado y otros más instrumentales, que debería atender una reforma administrativa si aspira a ser completa.

    This document contains the Users Manual of Visual Balan V1.0, an updated version of Visual Balan V0.0 (Samper et al., 1997). Visual Balan V1.0 performs daily water balances in the soil, the unsaturated zone and the aquifer in a user-friendly environment which facilitates both the input data process and the postprocessing of results. The main inputs of the balance are rainfall and irrigation while the outputs are surface runoff, evapotranspiration, interception, inter flow and groundwater flow. The code evaluates all these components in a sequential manner by starting with rainfall and irrigation, which must be provided by the user, and continuing with interception, surface runoff, evapotranspiration, and potential recharge (water flux crossing the bottom of the soil). This potential recharge is the input to the unsaturated zone where water can flow horizontally as subsurface flow (inter flow) or vertically as percolation into the aquifer. (Author)

    Full Text Available The modification of dietary patterns has led to a change in fatty acid consumption, with an increase in the consumption of ω-6 fatty acids and a markerd reduction in the consumption of ω-3 fatty acids. This in turn has given rise to an imbalance in the ω-6/ω-3 ratio, which is now very different from the original 1:1 ratio of humans in the past. Given the involvement of ω-6 and ω-3 essential fatty acids in disease processes, the present article examines changes in dietary patterns that have led to the present reduction in the consumption of ω-3 essential fatty acids, and to study the importance of the ω-6/ω-3 balance in maintaining good health. In addition, an assese-ment is made of the established recommendations for preventing a poor intake of ω-3 essential fatty acids, and the possible options for compensating the lack of these fatty acids in the diet.La modificación de los hábitos alimentarios ha llevado a un cambio en el consumo de ácidos grasos, con una aumento de los ácidos grasos ω-6 y una marcada reducción en el consumo de los ácidos grasos ω-3. Esto a su vez ha dado lugar a un desequilibrio en la relación ω-6/ω-3, muy diferente de la proporción original 1:1 que tenían los seres humanos en el pasado. Dada la importancia de la relación entre los ácidos grasos esenciales ω-6 y ω-3 en el desarrollo de diferentes enfermedades, en el presente artículo se examinan los cambios en los hábitos alimentarios que han llevado a la reducción en el consumo de ácidos grasos esenciales ω-3, y se estudia la importancia de este equilibrio en el mantenimiento de la salud. Además, se realiza una evaluación de las recomendaciones establecidas para prevenir una deficiencia en la ingesta de ácidos grasos esenciales ω-3, y las posibles opciones para compensar la falta de esos ácidos grasos en la dieta.

  3. La rappresentazione del sogno, due modelli a confronto: la metapsicologia di Sigmund Freud e la teoria del Codice Multiplo di Wilma Bucci

    Ilaria Bellavia

    2007-09-01

    Full Text Available Obiettivo di questo lavoro è quello di fornire le principali linee di orientamento teorico dell’approccio psicodinamico relative alla funzione del sogno. In tal senso ci si avvarrà della metapsicologia Freudiana, ma anche dei prestigiosi contributi sul carattere del sogno portati da Wilma Bucci. In particolare, si proporrà un parallelismo tra la metapsicologia e la teoria del Codice Multiplo. La teoria energetica di derivazione psicoanalitica mette in risalto alcuni punti cardine sul ruolo del sogno: 1 il sogno deriva dall’energia di un desiderio inconscio; 2 i sogni hanno la funzione di preservare il sonno; 3 la nozione di un censore che si attiva per distorcere e mascherare i contenuti latenti; 4 i contenuti manifesti hanno la funzione di nascondere il reale significato del sogno. Secondo la teoria del codice multiplo, il sogno ha un valore là dove fornisce l’accesso al significato emotivo che è stato dissociato, ma la funzione dell’elaborazione dell’informazione emotiva nel sogno è sovrapponibile a quella dell’elaborazione dell’informazione emotiva durante la veglia, in particolare per quanto riguarda il sonno REM.

    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.

    Full Text Available Diviso tra l’identificazione con il personaggio di Hester Prynne e la drammatizzazione del proprio ruolo di giurato popolare che lo inscrive nella comunità interpretativa interna al testo, il lettore di The Scarlet Letter assiste al realizzarsi, in sé, di una scissione tra voler-leggere e dover-leggere tale da minare alle fondamenta lettura e, dunque, giudizio; tutt’altro che maestro diretto di imparzialità, il romanzo svela, attraverso una calcolata strategia retorica, l’esser-situata di ogni prospettiva giudicante, l’inconsapevole assunzione di un punto di vista opposto agli investimenti emotivi cui il testo stesso invita: la tirannia dello sguardo, insomma, è a sua volta sottomessa al potere di un meccanismo che dello sguardo orienta l’angolazione, costringendo l’osservatore a prendere coscienza di quanto la sua visione non sia tanto esito di una scelta quanto, piuttosto, di un’originaria cecità. Se il lettore, in una certa misura, è giudice, né l’uno può decidere della propria lettura né l’altro del proprio giudizio: aporia, questa, che segnala come il risultato estremo del leggere e del giudicare sia, in entrambi i casi, la contestazione del diritto di compiere la medesima attività che si compie; la costruzione della lettura (e del giudizio, perfezionandosi, esegue la propria intrinseca decostruzione.

    2012-12-01

    Full Text Available Il contributo intende ripercorrere il ruolo che Omar Calabrese ha avuto nella fondazione della Semiotica dell’arte. Una disciplina che, in Italia, vede la sua nascita a partire dall’ultimo ventennio del secolo scorso e che lo studioso, recentemente scomparso, ha contribuito a delineare con precisione. Il volume La macchina della pittura è sicuramente il suo contributo più innovativo, più sistematico e anc’oggi attuale. All’epoca in cui è stato pubblicato, nel 1985, lanciava una duplice sfida: alla storia dell’arte tradizionale e alla semiotica. Alla prima perché imponeva un altro tipo di sguardo, capace di decifrare il modo in cui attraverso la forma è costruito il senso pittorico. Alla semiotica perché dimostra come la pittura sia in grado di produrre senso e addirittura contenga al suo interno i meccanismi per interpretarla.

Lo studio e' stato condotto su sette pazienti che lamentavano dolore al retropiede da piu' di quattro mesi (maschi/femmine=1/6), con eta' compresa tra 16 e 22 anni (eta' media 18,6 anni); 3/7 praticavano attivita' agonistica sportiva, 4/7 danza classica. In 2/7 pazienti l'os trigonum presentava margini irregolari con sclerosi subcondrale e ampliamento della sincondrosi. In 3/7 pazienti e' stata documentata tenosinovite del tendine flessore lungo dell'alluce causata verosimilmente dalla sua compressione e spostamento all'interno della propria guaina, senza ne' alterazione dell'intensita' di segnale dell'os trigonum, ne' ampliamento della sincondrosi. In 1/7 pazienti sono stati rilevati ipertrofia dell'os trigonum, modico ampliamento della sincondrosi e segni importanti di edema midollare nell'os trigonum e nel processo posteriore dell'astragalo. In 1/7 pazienti, pur in presenza di os trigonum rilevato all'esame radiologico tradizionale, l'esame RM non ha documentato alcuno dei segni da riferire a sindrome dell'os trigonum: la diagnosi definitiva e' stata tendinite achillea. La RM e' l'unica metodica che fornisce importanti informazioni sul coinvolgimento dei tessuti molli, della superficie condro-ossea e sulle reazioni sinoviali riuscendo percio' a dimostrare chiaramente l'eventuale coesistente tenosinovite del tendine flessore lungo dell'alluce ed inoltre provvedendo a fornire informazioni dettagliate per il corretto approccio terapeutico.

    I metodi probabilistici e statistici giocano un ruolo di primo piano sia nella scienza teorica e sperimentale che nelle applicazioni ingegneristiche, costituendo pertanto un elemento essenziale del bagaglio culturale che uno studente deve acquisire fin dai primi anni di apprendimento universitario. Questo libro, che nasce dall’esperienza didattica accumulata dall’autore nell’insegnamento dei metodi sperimentali, si propone di fornire un’introduzione al calcolo delle probabilità e alla teoria degli errori facendo uso di uno stile di presentazione volutamente informale e traendo spunto da concrete applicazioni sperimentali, spesso attraverso esempi di notevole importanza storica. Così, per esempio, argomenti quali il moto browniano, la diffusione di luce, il decadimento radioattivo, la fisiologia della visione, le statistiche quantistiche e di fotorivelazione, vengono utilizzati per delucidare concetti chiave dell’analisi statistica e probabilistica. Un'enfasi particolare è posta sull’origine e l...

    Full Text Available A partire dagli scritti di Roman Jakobson, Nicolas Ruwet, Jean-Jacques Nattiez e Gino Stefani, la relazione tra la semiotica e la musica è stata spesso affrontata da numerosi studiosi che anche oggi praticano, specie in Canada, in Finlandia e in Italia, la disciplina chiamata “semiotica (o semiologia della musica”. Negli ultimi anni, in questo ambito spesso si è preferito realizzare studi su alcuni problemi specifici piuttosto che concentrarsi su una teorizzazione generale. Al contrario, Stefano Jacoviello, dopo aver pubblicato brevi saggi di carattere prevalentemente analitico, in questo volume, di ampio respiro teorico, presenta una sorta di manifesto teso a rilanciare, specie in Italia, il ruolo della “semiotica del discorso musicale” come disciplina particolarmente adatta ad affrontare questioni teoriche generali.

    Full Text Available L'articolo illustra il ruolo del feticcio nel percorso di appropriazione dell’individualità da parte dell’eroe romanzesco, ricorrendo a esempi letterari dedicati all’età di formazione: non solo storie per l’infanzia, quindi, ma, più ampiamente, vicende in cui il desiderio sostanziale del protagonista si concentra nella “scoperta del Sé”, un Selbst junghiano che cresce e si configura nel suo rapporto con l’Ombra. In questo itinerario i feticci attorniano l’individuo come strumenti, mezzi magici e specchi – non solo della persona ma anche del desiderio stesso. Il discorso si concentra sull’appropriazione dell’identità maschile, sui suoi tranelli e sulle sue insidie. Gli autori presi in considerazione sono Virginia Woolf, Jules Renard, James Matthew Barrie, Joanne K. Rowling e Arthur Schnitzler. Il procedimento critico intende tracciare paralleli fra i classici che hanno forgiato l’immaginario occidentale e le radici più antiche – orientali – delle saghe eroiche (le storie di Gilgamesh; il mito di Indra e Naamuci passando per l’epica cavalleresca (Sir Gawain e il Cavaliere Verde. Un’indicazione illuminante, in questo senso, viene dal critico angloindiano Ananda Coomaraswamy.

    Full Text Available La posizione centrale nell’Egeo ed i pochi giorni di navigazione dall’Africa e dall’Egitto, come dalla Siria e Palestina, hanno reso la città di Gortina, e Creta stessa, un punto nevralgico all’interno delle rotte commerciali di collegamento e distribuzione di beni tra le sponde del Mediterraneo. Lo studio delle anfore rinvenute nelle campagne di scavo 2003-2006 presso le Terme a sud del Pretorio, ed il necessario confronto con le grandi quantità di materiali provenienti soprattutto dai contesti del Pretorio confermano questa intricata rete commerciale. Già tra Ellenismo e prima età imperiale romana, Gortina svolse una funzione di mercato di raccolta e probabilmente di smistamento delle merci provenienti dall’Occidente e dall’Egeo, assumendo poi nella piena età imperiale, un ruolo sempre più attivo nella produzione delle stesse. La mutata situazione socio-economica dell’età tardo romana - bizantina, nonché la fondazione di una nuova capitale, Costantinopoli, portò Creta e Gortina ad avere scambi commerciali e collegamenti intensi soprattutto con le aree orientali del Mediterraneo privilegiando l’importazione di prodotti dall’esterno.

    Obiettivi: valutazione della prevalenza di fumatori negli studenti di medicina e di infermieristica al fine di migliorarne le competenze e i comportamenti in tema di tabagismo, in vista anche del loro futuro ruolo nelle Aziende Sanitarie1.

    Materiali e metodi: nell’ambito della Facoltà di Medicina dell’Università di Bologna è stato condotto uno studio sugli aspetti motivazionali e comportamentali delle abitudini al fumo nei giovani iscritti al primo anno di Medicina e di Infermieristica negli AA 1999-2000 e 2002-2003. L’indagine è stata svolta somministrando questionari anonimi agli studenti in aula. Si è ottenuta così una percentuale di rispondenti pari all’ 87 e al 90% della popolazione studentesca iscritta. Risultati: la prevalenza di fumatori cronici o occasionali è andata incrementandosi negli ultimi due anni del 7% tra gli studenti di infermieristica e dell’8,8% tra quelli di medicina, sino a raggiungere rispettivamente il 42,4% e il 25,7%. Nel 2002 il 13,5% dei fumatori ha dichiarato di contemplare la possibilità di smettere entro la fine del corso di studi. Nonostante la giovane età, il 10% di loro erano recidivi da tentativi di disassuefazione falliti.

    Conclusioni: evidente il trend di aumento dell’abitudine al fumo nelle categorie considerate e la difficoltà, a volte notevole, di evitare ricadute nel tabagismo in assenza di adeguato sostegno. Da questi dati è emersa la necessità di impegnarsi per garantire agli studenti sia una più specifica preparazione (si è previsto nel curriculum studi un modulo elective sul tabagismo che una possibilità di disassuefazione precoce, grazie a un canale preferenziale presso il centro per la Disassuefazione dal Fumo di Tabacco dell’ Azienda S.

    Pelvic floor and rectal prolapse conditions have greatly benefited by new imaging and instrumental diagnostic approaches, and especially defecography, for both pathophysiological interpretation and differential diagnosis. The authors investigated the efficacy of defecography in the assessment of rectal prolapse, and in particular the role of videproctography in diagnosis such dynamic disorders. The dynamic changes of ampulla are well depicted by videoproctography, which showed anorectum normalization and spontaneous reduction of invagination after intussusception. Defecography exhibited good capabilities in showing rectal wall function abnormalities. Finally, some features of videoproctography such as low radiation dose, non-invasiveness and ease of execution, make the examination acceptable to patients with anorectal disorders and for the follow-up of rectal prolapse.

    Full Text Available Background and Aim: All activities of daily living need to balance control in static and dynamic movements. In recent years, a numerous increase can be seen in the functional balance assessment tools. Functional balance tests emphasize on static and dynamic balance, balance in weight transfer, the equilibrium response to the imbalances, and functional mobility. These standardized and available tests assess performance and require minimal or no equipment and short time to run. Functional balance is prerequisite for the most static and dynamic activities in daily life and needs sufficient interaction between sensory and motor systems. According to the critical role of balance in everyday life, and wide application of functional balance tests in the diagnosis and assessment of patients, a review of the functional balance tests was performed.Methods: The Google Scholar, PubMed, Science Direct, Scopus, Magiran, Iran Medex, and IranDoc databases were reviewed and the reliable and valid tests which were mostly used by Iranian researchers were assessed.Conclusion: It seems that Berg balance scale (BBS have been studied by Iranian and foreign researches more than the other tests. This test has high reliability and validity in elderly and in the most neurological disorders.

    Purpose. To evaluate the role of contrast-enhanced Magnetic Resonance Mammography (MRM) in the evaluation of the contralateral breast in patients with recently diagnosed breast cancer. Materials and methods. Fifty patients with proved unilateral breast cancer, with a negative contralateral breast at physical examination, ultrasound and mammography, were studied with a 1.5 T magnet (Siemens, Vision Plus, Germany). A bilateral breast surface coil was used. Dynamic 3D Flash T1-weighted sequences were acquired in the axial plane before and 0, 2, 4, 6 and 8 minutes after the administration of 0.1 mmol/kg of Gd-BOPTA at a flow rate of 2 ml/s followed by 10 ml of saline. The level of suspicion was reported on a scale from 0 to 5 following the BI-RADS classification, based on lesion morphology and kinetic features. The results were compared with the histological findings after biopsy or surgery. Results. Fourteen out of 50 patients (28%) had contralateral lesions identified on MRM. Biopsy was performed in four of them for suspicious lesions (BI-RADS 4) while 10 patients underwent surgery because of highly suggestive malignant lesions (BI-RADS 5). Histology diagnosed three fibroadenomas, 5 ductal carcinoma in situ, 2 lobular carcinomas in situ, 3 invasive ductal carcinomas and 1 invasive lobular carcinoma. Contrast enhanced MRM yielded no false negative and three false positives. Conclusions. Our results demonstrate a very good accuracy of Magnetic Resonance Mammography in the detection of synchronous contralateral cancer in patients with newly diagnosed breast cancer. Therefore, contrast-enhanced MRM could be introduced to screen patients with proven breast cancer before they under-go surgery. [Italian] Scopo.

    Jagd, Søren

    This paper focuses on the leadership challenge of balancing trust and control. The relation between trust and control has for a long time been a puzzling issue for management researchers. In the paper I first show that there has been a dramatic change in the way the relation between trust...... and control has been conceptualized in trust research. While the relation between trust and control earlier was conceptualized as a more or less stable balance between trust and control, more recent research conceptualizes the relation between trust and control more as a dynamical process that involves...... an ongoing process of balancing the relation between trust and control. Second, taking the departure in the recent conceptualization of the balance between trust and control as an interactive process I discuss the challenges for management in handling this more subtle balancing of trust and control...

    Full Text Available Los Beatos son códices medievales españoles que hacen referencia al Apocalipsis. El texto está profusamente acompañado de miniaturas con personajes humanos y celestiales. El Beato de San Andrés de Arroyo es uno de ellos. Hemos realizado un análisis anatómico y postural de las figuras que aparecen en estos Beatos. Hemos encontrado figuras humanas y celestiales cuya postura y equilibrio son disarmónicas, contrariando a la fisiología. De otro lado hemos encontrado otras figuras que mantienen un perfecto equilibrio, representando correctamente el movimiento y la estática. Creemos en base a todo ello que en el Beato de San Andrés de Arroyo hubo más de un artista iluminador, uno de ellos era más naturalista que el otro u otros.The Beatuses are Spanish medieval codices that refer to the Apocalypses. Miniatures full of human and celestial characters accompany the text. The Beatus of San Andrés de Arroyo is one of them. We have made an anatomic and postural analysis of the figures of this Beatus.

On the other hand we have found other figures that maintain a perfect balance, representing movement and motionlessness correctly.We believe, based on all this, that there is more than one Beatus de San Andrés de Arroyo illustrator, one of them being more of a naturalist than the other.

    In the study of the climatic change tied to the anthropogenic enhancement of the greenhouse effect, a very important topic is represented by the past climate reconstruction. This because the analysis of the past variations can help in order to better understand the present trends. With this aim a research on the climatic trends in Italy has been carried out considering the main meteorological parameters. The obtained results indicate that the climate has been subject to a noticeable evolution even if, due to reduced amplitude of the variations, it is not possible to state without any doubt that it is a real climatic change. The present patterns can in fact be connected to the natural climatic variability. [Italian] Nello studio dei cambiamenti climatici legati al potenziamento antropico dell'effetto serra, un ruolo importante riveste la ricostruzione dei climi del passato, poiche' l'analisi delle variazioni passate puo' aiutare a capire meglio gli andamenti attuali. In questa prospettiva, e' stato effetuata una indagine sull'andamento del clima in Italia nel secondo dopoguerra prendendo in considerazione i principali parametri meteorologici. I risultati ottenuti indicano che il clima ha subito una consistente evoluzione, anche se l'ampiezza delle variazioni non consente di affermare che si e' di fronte ad un vero e proprio cambiamento.

    Full Text Available Objective: To quantify the differences in the trajectory of the center of pressure (COP in an elderly population and a group of children. Methods: This was a cross-section study for which a convenience sample of 38 elderly adults and 20 children was obtained. The parameters studied were: area and average speed of excursion of the COP, and the frequency bands (0.0625; 0.125; 0.25; 0.5; 1, 2 y 4 Hz. Results: During the standing balance evaluation in the absence of the visual system, there are significant differencesin the area and average velocity of the COP. The group of children generates much more area of COP during the test than the elder group (p = 0.009. However, postural adjustments in children are faster than those of the older group (p = 0.002. Conclusions: In the absence of the visual system, the elderly group had lower area and speed of postural adjustment than the younger group. The latter group used the vestibular and somatosensory systems to maintain standing balance.

    2011-04-01

    Full Text Available Le celebrazioni per i 150 anni dell’Unità d’Italia offrono anche l’occasione per interrogarsi sulla storia e lo sviluppo di questo Paese, in particolare in riferimento alla cultura del mare e al sistema dei trasporti via acqua. In un paese peninsulare come l’Italia, con i suoi 7.500 chilometri di fronte d’acqua, la presenza dei porti è sempre stata elemento determinante per la crescita economica e per la sua affermazione sui mercati internazionali. Ma, dalla seconda metà del Novecento, le città e i loro porti sono andati progressivamente separandosi, determinando situazioni di forti contrasti e di continue tensioni. Solo più recentemente – a seguito della legge n. 84 del 1994 – nuove forme di ‘dialogo’ hanno consentito, in talune occasioni, di riavviare politiche di concertazione sui piani di sviluppo delle aree portuali e sul miglioramento della situazione delle zone urbane prossime ai porti. Per tutti questi motivi, l’occasione del 150esimo anniversario dell’Unità d’Italia può rappresentare un momento significativo per riprendere la riflessione sul ruolo dei porti italiani nella storia del nostro paese, ed, eventualmente, sul potenziale rafforzamento che essi possono subire, alla luce dei dati positivi ed incoraggianti dell’intero cluster marittimo in questi ultimi anni, almeno fino alla crisi congiunturale del 2008.Al tempo stesso, si può analizzare la complessa relazione porto-città, in un’ottica di mutuo riconoscimento delle rispettive esigenze e della volontà di sviluppare le proprie attività in un quadro di concreto ed efficace spirito di collaborazione, che richiede sia una maggiore conoscenza reciproca, così come una più efficace definizione degli obiettivi per il raggiungimento di una qualità urbana sostenibile e duratura.La progressiva globalizzazione dell’economia e la liberalizzazione del mercato hanno determinato una generale crescita degli scambi commerciali a livello mondiale e in

    Full Text Available Dai documenti qui pubblicati apprendiamo che uno dei maggiori editori-stampatori attivi a Firenze alla fine del sedicesimo secolo, Giorgio Marescotti, si faceva sempre pagare dagli autori, senza eccezione. Il fenomeno non è sconosciuto ma la sua categoricità e la sua estensione implicano la presenza di un sistema, funzionante e condiviso da tutti i soggetti, in cui l’editore non aveva quel ruolo di promotore culturale che invece con troppa facilità gli storici attribuiscono a chiunque abbia nel passato sottoscritto un prodotto editoriale.Questi documenti ci permettono poi di criticare l′uso, sempre improprio avanti la nascita dell′editoria moderna, di categorie quali linea o politica editoriale, logica di mercato, editore commerciale o «minore». Come risulta dalla presente ricerca Marescotti e i suoi colleghi non rischiavano se non per (pochi generi di smercio sicuro perchè non erano in grado di capire il potenziale di un libro, né di immaginarne il pubblico; ed è un errore cercare – e peggio ancora trovare - una logica culturale nei loro Annali. Speculare, infine, la posizione degli autori, che non solo pagavano senza prospettive di guadagno, ma non potevano né disporre a piacere delle copie del loro libro né controllare la trasformazione del loro testo senza maggiori aggravi.

  13. Load Balancing Scientific Applications

    Pearce, Olga Tkachyshyn [Texas A & M Univ., College Station, TX (United States)

    2014-12-01

    The largest supercomputers have millions of independent processors, and concurrency levels are rapidly increasing. For ideal efficiency, developers of the simulations that run on these machines must ensure that computational work is evenly balanced among processors. Assigning work evenly is challenging because many large modern parallel codes simulate behavior of physical systems that evolve over time, and their workloads change over time. Furthermore, the cost of imbalanced load increases with scale because most large-scale scientific simulations today use a Single Program Multiple Data (SPMD) parallel programming model, and an increasing number of processors will wait for the slowest one at the synchronization points. To address load imbalance, many large-scale parallel applications use dynamic load balance algorithms to redistribute work evenly. The research objective of this dissertation is to develop methods to decide when and how to load balance the application, and to balance it effectively and affordably. We measure and evaluate the computational load of the application, and develop strategies to decide when and how to correct the imbalance. Depending on the simulation, a fast, local load balance algorithm may be suitable, or a more sophisticated and expensive algorithm may be required. We developed a model for comparison of load balance algorithms for a specific state of the simulation that enables the selection of a balancing algorithm that will minimize overall runtime.

    The quasi-balance of extra-tropical tropospheric dynamics is a fundamental aspect of nature. If an atmospheric analysis does not reflect such balance sufficiently well, the subsequent forecast will exhibit unrealistic behavior associated with spurious fast-propagating gravity waves. Even if these eventually damp, they can create poor background fields for a subsequent analysis or interact with moist physics to create spurious precipitation. The nature of this problem will be described along with the reasons for atmospheric balance and techniques for mitigating imbalances. Attention will be focused on fundamental issues rather than on recipes for various techniques.

    The time is fast approaching when the SI unit of mass will cease to be based on a single material artefact and will instead be based upon the defined value of a fundamental constant—the Planck constant—h . This change requires that techniques exist both to determine the appropriate value to be assigned to the constant, and to measure mass in terms of the redefined unit. It is important to ensure that these techniques are accurate and reliable to allow full advantage to be taken of the stability and universality provided by the new definition and to guarantee the continuity of the world's mass measurements, which can affect the measurement of many other quantities such as energy and force. Up to now, efforts to provide the basis for such a redefinition of the kilogram were mainly concerned with resolving the discrepancies between individual implementations of the two principal techniques: the x-ray crystal density (XRCD) method [1] and the watt and joule balance methods which are the subject of this special issue. The first three papers report results from the NRC and NIST watt balance groups and the NIM joule balance group. The result from the NRC (formerly the NPL Mk II) watt balance is the first to be reported with a relative standard uncertainty below 2 × 10-8 and the NIST result has a relative standard uncertainty below 5 × 10-8. Both results are shown in figure 1 along with some previous results; the result from the NIM group is not shown on the plot but has a relative uncertainty of 8.9 × 10-6 and is consistent with all the results shown. The Consultative Committee for Mass and Related Quantities (CCM) in its meeting in 2013 produced a resolution [2] which set out the requirements for the number, type and quality of results intended to support the redefinition of the kilogram and required that there should be agreement between them. These results from NRC, NIST and the IAC may be considered to meet these requirements and are likely to be widely debated

    Full Text Available A previous study conducted in 1998 assessed yearly nutrient discharge by the Sinaloa and Sonora shrimp farms to the coastal areas of the Gulf of California (1,509.4 and 438.7 tons of N and P corresponding to 2.1 and 1.05% of the total nutrient discharges to the Gulf along those two states coastlines. However, that estimate did not take into account other nutrient sources, nor the high daily water exchanges of the farms of Sonora, that are likely to increase the calculated amount of nutrients discharged. The evaluation of the nutrient budget of one semi-intensive shrimp farm of Sonora, including the nutrient sources not measured in other studies, showed that during one production cycle this farm discharged 547 kg N·ha-1 and 73 kg P·ha-1, with respective net exports of 122 kg N·ha-1 and 14 kg P·ha-1. Based on the results of this study, the recalculated totals for Sinaloa and Sonora, including rivers, agricultural runoff, and urban wastewater were 77,007.7 and 38,108.3 tons of N and P, and those of shrimp farms 3,556 tons of N and 620.7 tons of P (4.8 and 1.6%. The total discharges of 2003 may be estimated at 78,798.2 and 38,874.1 tons of N and P. In view of its high groth rate, the contributions of shrimp culture would be 10.1% and 3.3%.En un estudio llevado a cabo en 1998, se evaluó la cantidad de nutrientes descargada anualmente hacia las áreas costeras del Golfo de California por las granjas camaroneras de Sinaloa y Sonora en 1998 (1,509.4 ton de N y 438.7 ton de P, equivalentes a 2.1 y 1.05% del total de las descargas de ambos estados.

Aligning your behavior with your values is much like any other developmental experience; the basic process involves assessment, challenge, and support. You need to determine where you are, define where you want to go, and then put into place the tools you need to get there.Balance is about more than how you spend your time.

    Two wind tunnel techniques for determining part of the aerodynamic information required to describe the dynamic bahavior of various types of vehicles in flight are described. Force and moment measurements are determined with a rotary-balance apparatus in a coning motion and with a Magnus balance in a high-speed spinning motion. Coning motion is pertinent to both aircraft and missiles, and spinning is important for spin stabilized missiles. Basic principles of both techniques are described, and specific examples of each type of apparatus are presented. Typical experimental results are also discussed.

Lo studio delle emissioni monetarie conferma il suo testo e permette di dedurre alcuni aspetti in merito agli eventi che portarono Godas al potere nell'isola e che non sono stati narrati dallo storico palestino. Ciò permette di correggere un'inesatta interpretazione dei fatti data dagli storici sardi, i quali, basandosi sulla traduzione latina invece che sull'originale greco, scrivono che Godas fu inviato in Sardegna dal re vandalo Gelamir: invece il suo ruolo nell'isola fu necessariamente importante già durante il regno di Hilderico, il suo predecessore. L'articolo è completato dal corpus di tutti gli esemplari noti di nummi battuti in nome di Godas.

    Full Text Available La energía potencial del agua presenta diferencias de un punto del suelo a otro; esas diferencias son las que originan el movimiento del agua de acuerdo a la tendencia universal de la materia en el sentido de moverse de donde la energía potencial es mayor a donde dicha energía es menor. En el suelo el agua en consecuencia se mueve hacia donde su energía decrece hasta lograr su estado de equilibrio. Se desprende entonces que la cantidad de energía potencial absoluta contenida en el agua, no es importante por sí misma, sino por su relación con la energía en diferentes lugares dentro del suelo. El concepto Potencial de agua del suelo es un criterio para esta energía.

    Full Text Available Spesso origine dei primi insediamenti urbani, i corsi d’acqua sono stati nei secoli fonte di sostentamento per le popolazioni e strumento di scambio tra genti e culture. Proprio per il loro scorrere attraverso il territorio, essi sono per definizione luoghi di relazione, di intersezione tra diverse realtà urbane dove si incontrano ambiente, architettura, pianificazione, trasporti ma anche arte, cultura e turismo. Per questa loro caratteristica, le vie d’acqua rappresentano una grande potenzialità per lo sviluppo del territorio sia in termini di mobilità – di merci e di persone - che di turismo sostenibile. La loro riqualificazione permette di recuperare il ruolo di spazio pubblico e di paesaggio rurale, urbano e turistico di qualità; luoghi di fruizione turistica, culturale, gastronomica e sportiva, quindi di qualità della vita. Dopo decenni di oblio, sollecitata dal rinnovato interesse verso questi assi e anche dalle direttive dell’Unione Europee, l’Italia e, in particolare il Nord del paese, muove i primi passi verso la valorizzazione delle waterway a fini turistico-culturali, aprendo nuove possibilità di sviluppo del territorio. Sia pur con ritardo rispetto ad altri Paesi, che da anni e in diverse forme valorizzano e “sfruttano” le vie d’acqua, si avverte anche in Italia un cambio di mentalità che vede nell’uso e nel recupero di tale risorsa uno strumento importante per garantire la sostenibilità ambientale ed economica e il recupero di una identità culturale quasi dimenticata.

    A new cell balancing technology was developed under a Department of Energy contract which merges the DC/DC converter function into cell balancing. Instead of conventional passive cell balancing technology which bypasses current through a resistor, or active cell balancing which moves current from one cell to another, with significant cost and additional inefficiencies, this concept takes variable amount of current from each cell or small group of cells and converts it to current for the low voltage system.

    2008-01-01

    Balance control and locomotor patterns were altered in Apollo crewmembers on the lunar surface, owing, presumably, to a combination of sensory-motor adaptation during transit and lunar surface operations, decreased environmental affordances associated with the reduced gravity, and restricted joint mobility as well as altered center-of-gravity caused by the EVA pressure suits. Dr. Paloski will discuss these factors, as well as the potential human and mission impacts of falls and malcoordination during planned lunar sortie and outpost missions. Learning objectives: What are the potential impacts of postural instabilities on the lunar surface? CME question: What factors affect balance control and gait stability on the moon? Answer: Sensory-motor adaptation to the lunar environment, reduced mechanical and visual affordances, and altered biomechanics caused by the EVA suit.

La propuesta de EF enfocada a las actividades de la vida diaria incluye fases que permiten adquirir la estabilidad hasta lograr el desarrollo de movimiento que demanden más agilidad. En la planificación del EF se deben estructurar los procesos a ejecutar considerando el criterio de funcionalidad. Para organizar la sesión del EF, el fisioterapeuta cuenta con tres maneras de planificar la sesión: globales, por hemisferios y por grupos musculares. Conclusión: La fundamentación teórica sobre el EF permite al fisioterapeuta comprender y determinar cómo esta modalidad de intervención repercute de manera positiva sobre el desempeño funcional y calidad de vida de los sujetos.

  7. Balanced Atmospheric Data Assimilation

    2017-04-01

    The atmosphere's multi-scale structure poses several major challenges in numerical weather prediction. One of these arises in the context of data assimilation. The large-scale dynamics of the atmosphere are balanced in the sense that acoustic or rapid internal wave oscillations generally come with negligibly small amplitudes. If triggered artificially, however, through inappropriate initialization or by data assimilation, such oscillations can have a detrimental effect on forecast quality as they interact with the moist aerothermodynamics of the atmosphere. In the setting of sequential Bayesian data assimilation, we therefore investigate two different strategies to reduce these artificial oscillations induced by the analysis step. On the one hand, we develop a new modification for a local ensemble transform Kalman filter, which penalizes imbalances via a minimization problem. On the other hand, we modify the first steps of the subsequent forecast to push the ensemble members back to the slow evolution. We therefore propose the use of certain asymptotically consistent integrators that can blend between the balanced and the unbalanced evolution model seamlessly. In our work, we furthermore present numerical results and performance of the proposed methods for two nonlinear ordinary differential equation models, where we can identify the different scales clearly. The first one is a Lorenz 96 model coupled with a wave equation. In this case the balance relation is linear and the imbalances are caused only by the localization of the filter. The second one is the elastic double pendulum where the balance relation itself is already highly nonlinear. In both cases the methods perform very well and could significantly reduce the imbalances and therefore increase the forecast quality of the slow variables.

    2010-06-01

    Full Text Available Debido a que la epidemia mundial de obesidad no muestra signos de disminución, se ha hecho necesaria una mejor comprensión de los mecanismos fisiológicos subyacentes a la homeostasis energética, el proceso mediante el cual el consumo energético se iguala al gasto energético a lo largo del tiempo, de manera que los almacenes energéticos corporales, en la forma de tejido adiposo, se mantienen constantes a pesar de las variaciones diarias en la ingesta calórica. El sistema que controla el balance energético posee, a su vez, dos componentes: uno en el corto y otro en el largo plazo. El sistema, en el corto plazo, se encarga de regular el apetito o inicio y finalización de comidas individuales, y responde, fundamentalmente, a hormonas gastrointestinales o señales de saciedad que se acumulan durante la alimentación y contribuyen a terminar la ingesta. Los factores de adiposidad, como la leptina e insulina, son señales que se liberan en proporción a los depósitos energéticos del organismo, y su función involucra la regulación del balance energético por periodos prolongados, por lo que se encargan de la estabilidad del peso corporal. La vía central de las melanocortinas representa un punto crucial de integración de estas señales. Los ligandos de los receptores de melanocortina son sintetizados en poblaciones neuronales discretas dentro del núcleo arcuado del hipotálamo, y ejercen acciones en los dos componentes del balance energético. Sumado a su capacidad de respuesta frente a los niveles de hormonas circulantes, el cerebro también responde directamente a los niveles circulantes de nutrientes. Se han identificado dos proteincinasas que sensan los niveles de nutrientes y funcionan como reguladoras del peso corporal y consumo energético en el hipotálamo: mTOR y AMPK. Además de estos circuitos homeostáticos, los mecanismos hedónicos de alimentación son importantes en la regulación del consumo energético, superando la

    Full Text Available Desde el punto de vista farmacológico, es importante comprender qué es el alcohol y cómo actúa en el organismo. No existe una causa simple, sino una interacción complicada de factores neuroquímicos, fisiológicos, psicológicos y sociales que originan y desarrollan esta grave enfermedad fármaco-dependiente. La acción psicofisiológica y farmacodinámica del alcohol es fundamentalmente depresiva, por la reducción de la transmisión sináptica en el sistema nervioso humano. Es un hecho conocido que el consumo excesivo de alcohol causa una disfunción aguda y crónica del cerebro, produciendo trastornos en el sistema nervioso central, presentando alteraciones en la memoria y en las funciones intelectuales como cálculo, comprensión y aprendizaje. A nivel hepático tiene lugar, en su mayoría, el metabolismo del alcohol, produciéndose un hígado graso alcohólico, aumentando el tamaño, terminando en necrosis e inflamación grave del hígado; esto se llama hepatitis alcohólica, y si se sigue consumiendo alcohol se desarrollará la cirrosis. El alcohol también ha estado relacionado con alteraciones del miocardio; se ha constatado en animales de experimentación sanos que tanto la velocidad de contracción del músculo cardiaco y su máxima tensión disminuyen en presencia del alcohol, como consecuencia, la fuerza de cada contracción y el aumento de presión en el ventrículo izquierdo son menores, perdiendo eficacia el corazón como bomba.

The performance was directed by the author of these pages for the Istituto nazionale del dramma antico (premiere: Siracusa, 11th May. In the framework of a hermeneutic paradigm based on the ‘critically’ untimely nature of the classic, the staging of Prometheus here discussed wanted to inquire the role of sight in the orchestration of this tragedy, as well as to account for the way time is treated in the text. In the light of this approach, Prometheus looks like a cruel portrait of a world in a state of crisis, suspended between two disasters (one has just ended, the other is looming ominously on the horizon; from its remote distance, such a world gives us an image both lucid and alienated of our present.Il saggio si propone di restituire il percorso di riflessione critica intorno al Prometeo incatenato che nella primavera del 2012 ha sostanziato il processo di messa in scena della tragedia presso il teatro greco di Siracusa, curata dall’autore di queste pagine per conto dell’Istituto nazionale del dramma antico (debutto: Siracusa, 11 maggio. Entro un paradigma ermeneutico fondato sul principio dell’inattualità ‘critica’ del classico, l’allestimento del Prometeo di cui qui si riferisce punta a indagare il ruolo svolto dallo sguardo nell’orchestrazione della tragedia, così come a render ragione del trattamento cui la funzione tempo è sottoposta nell’opera. Sulla base di un simile approccio, il Prometeo appare così come un crudele ritratto di un mondo in crisi sospeso tra due catastrofi (l’una appena trascorsa, l’altra minacciosamente incombente all’orizzonte; un mondo che dalla sua remota distanza ci consegna un’immagine ad un tempo lucida e straniata del nostro presente.

    Lesson "Balance in Nature" This simulation game-lesson (Balance in Nature) gives an opportunity for the students to show creativity, work independently, and to create models and ideas. It creates future-oriented thought connected to their experience, allowing them to propose solutions for global problems and personal responsibility for their activities. The class is divided in two teams. Each team chooses questions. 1. Question: Pollution in the environment. 2. Question: Care for nature and climate. The teams work on the chosen tasks. They make drafts, notes and formulate their solutions on small pieces of paper, explaining the impact on nature and society. They express their points of view using many different opinions. This generates alternative thoughts and results in creative solutions. With the new knowledge and positive behaviour defined, everybody realizes that they can do something positive towards nature and climate problems and the importance of individuals for solving global problems is evident. Our main goal is to recover the ecological balance, and everybody explains his or her own well-grounded opinions. In this work process the students obtain knowledge, skills and more responsible behaviour. This process, based on his or her own experience, dialogue and teamwork, helps the participant's self-development. Making the model "human↔ nature" expresses how human activities impact the natural Earth and how these impacts in turn affect society. Taking personal responsibility, we can reduce global warming and help the Earth. By helping nature we help ourselves. Teacher: Veselina Boycheva-Chapanova " Saint Patriarch Evtimii" Scholl Str.

  17. Energy balance in obesity.

    Science.gov (United States)

    Webber, Jonathan

    2003-05-01

    The current epidemic of human obesity implies that whilst energy balance appears to be regulated, the extent of this regulatory process is being overwhelmed in large numbers of the population by environmental changes. Clearly, the shift towards positive energy balance reflects both alterations in energy intake and decreases in physical activity. Increased energy intake and, in particular, the rising proportion of energy from fat is linked with obesity. However, on a population level reduced levels of activity probably play the predominant role. It is apparent that individual susceptibility to weight gain varies enormously. The factors underlying this susceptibility are an area of intense research interest. Variations in BMR from that predicted appear to be linked to the propensity to gain weight. The genes responsible for this variation may include uncoupling proteins-2 and -3, with a number of studies showing a link with obesity. However, in vivo studies of these proteins have not yet demonstrated a physiological role for them that would explain the link with obesity. Non-exercise activity thermogenesis may also protect from weight gain, but the regulation of this type of thermogenesis is unclear, although the sympathetic nervous system may be important. A profusion of hormones, cytokines and neurotransmitters is involved in regulating energy intake, but whilst mutations in leptin and the melanocortin-3 receptor are responsible for rare monogenic forms of obesity, their wider role in common polygenic obesity is not known. Much current work is directed at examining the interplay between genetic background and environmental factors, in particular diet, that both lead to positive energy balance and seem to make it so hard for many obese subjects to lose weight.

    The purpose of this article is to show how a System Dynamics Modelling approach can be integrated into the Balanced Scorecard (BSC) for a case company with special focus on the handling of causality in a dynamic perspective. The case company’s BSC model includes five perspectives and a number...... of financial and non-financial measures. The overall idea of BSC is to make the strategy operational, as proposed by Kaplan and Norton (1992; 1996; 2007) and to use the strategy for simulation. Our results indicate that a company may gain great learning insight from such simulation studies. The whole article...

    A network plan model of ship erection was established based on the network planning technologyand the work-package breakdown system. The load-oriented production control method was introduced to buildup a throughput diagram model thus it is possible to describe the ship erection process numerically. Based onthe digitaiized models some cases of production balance of ship erection were studied and three balance indexeswere put forward, they are the load balance rate, the input manpower balance rate and the maximum gantrycrane operating times. Such an analytic method based on the balance evaluation is the important foundationfor digitization and intelligentization of shipyard production management.

    2003-01-01

    The discrete scalar data need prefiltering when transformed by discrete multi-wavelet, but prefiltering will make some properties of multi-wavelets lost. Balanced multi-wavelets can avoid prefiltering. The sufficient and necessary condition of p-order balance for multi-wavelets in time domain, the interrelation between balance order and approximation order and the sampling property of balanced multi-wavelets are investigated. The algorithms of 1-0rder and 2-0rder balancing for multi-wavelets are obtained. The two algorithms both preserve the orthogonal relation between multi-scaling function and multi-wavelets. More importantly, balancing operation doesn't increase the length of filters, which suggests that a relatively short balanced multiwavelet can be constructed from an existing unbalanced multi-wavelet as short as possible.

    Full Text Available I macrofagi sono cellule del sistema immunitario che svolgono un ruolo fondamentale nel meccanismo di difesa dell’ospite contro gli agenti patogeni. Attualmente è ancora poco chiara la dinamica del loro intervento e della risposta umorale nel favorire l’attività fagocitaria nei confronti di Mycoplasma mycoides subsp. mycoides small colony (Mmm-SC, agente eziologico della pleuropolmonite contagiosa bovina (PPCB. Questo studio è stato condotto al fine di valutare le modificazioni morfologiche della superficie macrofagica in seguito all’infezione in vitro con Mmm-SC in presenza di siero immune bovino. L’analisi morfologica dei macrofagi è stata condotta su colture, 6 ore dopo l’infezione, utilizzando l’analisi tridimensionale della microscopia elettronica a scansione. I macrofagi non infettati, in presenza di siero negativo o immune, e i macrofagi infettati con Mmm-SC, in assenza di siero, hanno mostrato solo lievi modificazioni della loro superficie. Al contrario, in colture di macrofagi infettati e in presenza di siero immune sono state osservate marcate modificazioni della superficie cellulare, come ampi veli e filopodi (indicatori di attivazione cellulare, e piccoli aggregati di micoplasmi in stretto contatto con le membrane macrofagiche. I risultati suggeriscono che la risposta umorale specifica per Mmm-SC può contribuire a innescare l’attività fagocitaria dei macrofagi.

Experiments, research, and experience see positive effects of adding sign language in communication methods to pre-school and K-12 education. Augmentative, alternative, interactive, accommodating, and enriching strategies using sign language aid learners in balancing the skills needed to mastery of one language or multiple languages. Theories of learning that embrace play, drama, motion, repetition, socializing, and self-efficacy connect to the options for using sign language with learners in inclusive and mainstream classes. The methodical use of sign language by this researcher-educator over two and a half decades showed signing does build thinking skills, add enjoyment, stimulate communication, expand comprehension, increase vocabulary acquisition, encourage collaboration, and helps build appreciation for cultural diversity.

    We propose a simple distributed algorithm for balancing indivisible tokens on graphs. The algorithm is completely deterministic, though it tries to imitate (and enhance) a random algorithm by keeping the accumulated rounding errors as small as possible. Our new algorithm surprisingly closely approximates the idealized process (where the tokens are divisible) on important network topologies. On d-dimensional torus graphs with n nodes it deviates from the idealized process only by an additive constant. In contrast to that, the randomized rounding approach of Friedrich and Sauerwald (2009) can deviate up to Omega(polylog(n)) and the deterministic algorithm of Rabani, Sinclair and Wanka (1998) has a deviation of Omega(n^{1/d}). This makes our quasirandom algorithm the first known algorithm for this setting which is optimal both in time and achieved smoothness. We further show that also on the hypercube our algorithm has a smaller deviation from the idealized process than the previous algorithms.

    Fidelity is the ethical obligation to act in good faith to keep promises, fulfill agreements, and maintain relationships and fiduciary responsibilities. Consumers are increasingly interested in the balance between the fiscal viability of our current healthcare delivery system and the system's reason for existence--that is, to serve the health needs of clients. Escalating healthcare costs have driven many institutions and third party payors to examine service and payment practices. Some consumers and consumer rights groups contend that these evolving practices threaten the very essence of health and healthcare. The ethical obligation of fidelity, especially as it relates to the business model of healthcare, is examined. Threats to fidelity are reviewed, and the response to these threats by one consumer rights group is presented. A case study is included.

    Abstract Social conflict, in the form of intraspecific selfish "cheating" has been observed in a number of natural systems. However, a formal, evolutionary genetic theory of social cheating that provides an explanatory, predictive framework for these observations is lacking. Here we derive the kin...... selection-mutation balance, which provides an evolutionary null hypothesis for the statics and dynamics of cheating. When social interactions have linear fitness effects and Hamilton´s rule is satisfied, selection is never strong enough to eliminate recurrent cheater mutants from a population, but cheater...... lineages are transient and do not invade. Instead, cheating lineages are eliminated by kin selection but are constantly reintroduced by mutation, maintaining a stable equilibrium frequency of cheaters. The presence of cheaters at equilibrium creates a "cheater load" that selects for mechanisms of cheater...

Key-lexemes such as caritat, fealtat, profit comú are analysed within Eiximenis's political discourse. An analysis is also made of the role they play in the definition of an exclusively Christian community organization connoted by a close interdependence between res publica and market, i.e. the validation paradigms of the political institution and the paradigms that legitimate a reliable trading space. Moreover, the ideas and projects of the Minorite from Gerona are tested in the actual institutional context in which he acts: the Kingdom of Valencia and that of Sicily after the 1392 Conquest.

Le idee ed i progetti del Gerundense sono inoltre verificati nel concreto contesto istituzionale in cui egli opera: il regno di Valencia e quello di Sicilia all'indomani della conquista del 1392.

  15. Energy balance in peridynamics.

    Energy Technology Data Exchange (ETDEWEB)

    Lehoucq, Richard B.; Silling, Stewart Andrew

    2010-09-01

    The peridynamic model of solid mechanics treats internal forces within a continuum through interactions across finite distances. These forces are determined through a constitutive model that, in the case of an elastic material, permits the strain energy density at a point to depend on the collective deformation of all the material within some finite distance of it. The forces between points are evaluated from the Frechet derivative of this strain energy density with respect to the deformation map. The resulting equation of motion is an integro-differential equation written in terms of these interparticle forces, rather than the traditional stress tensor field. Recent work on peridynamics has elucidated the energy balance in the presence of these long-range forces. We have derived the appropriate analogue of stress power, called absorbed power, that leads to a satisfactory definition of internal energy. This internal energy is additive, allowing us to meaningfully define an internal energy density field in the body. An expression for the local first law of thermodynamics within peridynamics combines this mechanical component, the absorbed power, with heat transport. The global statement of the energy balance over a subregion can be expressed in a form in which the mechanical and thermal terms contain only interactions between the interior of the subregion and the exterior, in a form anticipated by Noll in 1955. The local form of this first law within peridynamics, coupled with the second law as expressed in the Clausius-Duhem inequality, is amenable to the Coleman-Noll procedure for deriving restrictions on the constitutive model for thermomechanical response. Using an idea suggested by Fried in the context of systems of discrete particles, this procedure leads to a dissipation inequality for peridynamics that has a surprising form. It also leads to a thermodynamically consistent way to treat damage within the theory, shedding light on how damage, including the

    When multiple channels are employed in a pulse-Doppler radar, achieving and maintaining balance between the channels is problematic. In some circumstances the channels may be commutated to achieve adequate balance. Commutation is the switching, trading, toggling, or multiplexing of the channels between signal paths. Commutation allows modulating the imbalance energy away from the balanced energy in Doppler, where it can be mitigated with filtering.

    Concerns about inadequate patient hydration and suboptimal monitoring of fluid balance have been documented in recent reports. The Fluid Balance Improvement Project at Central Manchester University Hospitals NHS Foundation Trust was undertaken to identify risk factors influencing hydration and to implement a revised process to manage these risks, resulting in the development of a hydration pathway. This new approach to monitoring patient hydration, together with staff education and support, has resulted in improved compliance with fluid balance monitoring standards, as well as significant improvements in identifying patients at risk of dehydration, and an increase in patients with acute kidney injury commencing appropriate fluid balance monitoring.

The paper uses the tools of microeconomics to build a mathematical model of structural realism. The simple model reiterates...... the structural realist prediction that the weaker states should balance the unipole. Under a slight model extension, it is shown that efforts to balance in separate capabilities always tends to offset each other. Under this extension, the durability of the unipolar moment is in fact consistent...

    2012-04-01

    Full Text Available Nei primi anni ’50, Franco Modigliani e il suo studente Richard Brumberg elaborarono una teoria della spesa fondata sull’idea che gli individui effettuano scelte intelligenti su quanto desiderano spendere a ogni età, con il solo limite delle risorse disponibili nel corso della loro vita. Attraverso l’accumulo e il decumulo delle attività, chi lavora può provvedere alla propria pensione e, più in generale, può adattare i propri modelli di consumo alle esigenze che si presentano alle diverse età, indipendentemente dal reddito disponibile in ogni momento della sua vita. Questa semplice teoria conduce a previsioni rilevanti e non scontate per l’economia nel suo complesso, ad esempio che il risparmio nazionale dipende dal tasso di crescita del reddito nazionale e non dal suo livello, e che esiste una semplice relazione tra il livello della ricchezza nel sistema economico e la lunghezza del periodo trascorso in pensione. Tali previsioni, non verificabili negli anni ’50, hanno trovato considerevole sostegno empirico in successivi lavori di Modigliani e di altri ricercatori. Sebbene nel corso degli anni la teoria del consumo abbia subito numerosi attacchi, i più recenti dei quali mossi da una coalizione di psicologi ed economisti, l’ipotesi del ciclo vitale rimane una parte essenziale del pensiero degli economisti. Senza di essa avremmo molto meno da dire circa molte importanti questioni, quali l’offerta pubblica e privata di previdenza sociale, gli effetti del mercato azionario sull’economia, le conseguenze dei mutamenti demografici sul risparmio nazionale, il ruolo del risparmio nella crescita economica e le determinanti della ricchezza nazionale.  In the early '50s, Franco Modigliani and his student Richard Brumberg elaborated a theory of expenditure based on the idea that individuals make smart choices about how they want to spend at any age, with the only limit of the available resources in the course of

    Despite the prolongation of coagulation tests, recent studies reported an increased frequency of thromboembolic events in patients with cirrhosis. The aim of this study was to evaluate the haemostatic balance in cirrhotic patients through assessing the variation of pro- and anticoagulant factors and evaluating the in-vitro thrombin generation in patients with cirrhosis and in healthy patients. Fifty-one cirrhotic patients with or without thromboembolic events and 50 controls matched by age and sex were enrolled. Procoagulant (factors VII, II, V, VIII, and XII) and inhibitor (protein C, protein S and antithrombin) factor activities were determined. Thrombin generation was measured as endogenous thrombin potential (ETP). Haemostatic balance was assessed by means of both procoagulant to inhibitor coagulation factor ratios and ETP with to without protein C activation ratios. There were 24 males and 27 females. The mean age was 57.8 years [16-91 years]. Pro and anticoagulant factors were significantly lower in patients than in controls (P < 0.001) except for factor VIII and protein S. In fact factor VIII level was significantly higher in patients than in controls and protein S levels were not significantly different between patients and controls. Almost all the pro to anticoagulant factor ratios were higher in cirrhotics than in controls, especially the factor VIII to protein C ratios which increased significantly from Child Pugh A to C (P < 0.001), the ratio of ETP with to without protein C activator was higher in patients than in controls, but did not reach a significant level (0.8 vs. 0.52) There was no statistically significant difference between Child classes. When comparing patients with history of thrombosis (n = 7) to those matched by age and sex and without history of thrombosis (n = 14), the ratios were not statistically different between the two groups. Haemostatic changes in cirrhosis tend to rebalance the haemostatic system. This state often

    Over the course of her career as a physicist, Felicitas Pauss, currently responsible for CERN's External Relations, has often been the sole woman in an environment dominated by men. While she freely admits that being a woman physicist can have as many advantages as disadvantages, she thinks the best strategy is to maintain the right balance.   From a very early age, Felicitas Pauss always wanted to be involved in projects that interested and fascinated her. That's how she came to study physics. When she was a first-year university student in Austria in 1970, it was still fairly uncommon for women to go into physics research. "I grew up in Salzburg with a background in music. At that time, it was certainly considered more ‘normal’ for a woman to study music than to do research in physics. But already in high school I was interested in physics and technical instruments and wanted to know how things work and what they are made of”. At the beginning of her care...

  6. A balanced memory network.

    2007-09-01

    Full Text Available A fundamental problem in neuroscience is understanding how working memory--the ability to store information at intermediate timescales, like tens of seconds--is implemented in realistic neuronal networks. The most likely candidate mechanism is the attractor network, and a great deal of effort has gone toward investigating it theoretically. Yet, despite almost a quarter century of intense work, attractor networks are not fully understood. In particular, there are still two unanswered questions. First, how is it that attractor networks exhibit irregular firing, as is observed experimentally during working memory tasks? And second, how many memories can be stored under biologically realistic conditions? Here we answer both questions by studying an attractor neural network in which inhibition and excitation balance each other. Using mean-field analysis, we derive a three-variable description of attractor networks. From this description it follows that irregular firing can exist only if the number of neurons involved in a memory is large. The same mean-field analysis also shows that the number of memories that can be stored in a network scales with the number of excitatory connections, a result that has been suggested for simple models but never shown for realistic ones. Both of these predictions are verified using simulations with large networks of spiking neurons.

  7. [Mobility and balance].

    2008-08-01

    Quality of life is strongly associated with the mobility of elderly people. Falls often cause restricted mobility, a decline in activities of daily living and an increased risk of institutionalisation. Frailty, commonly associated with aging, is a biologic syndrome of decreased resistance to stressors, resulting from declines across multiple physiological systems. Changes in mobility and gait constitute part of the frailty syndrome. Since more than one third of persons over the age of 65 fall each year, prevention of falls is very important. Already while taking the patients' history special emphasis should be laid on matters associated with an increased risk of falling, such as the use of more than four medications. To assess mobility several brief tests exist (i.e. Timed up & go [17], Walking while Talking [20]) which immediately yield information regarding mobility and falling risk. Patients with poor performance on such tests or those with a history of several falls should undergo a spatio-temporal gait analysis in order to determine a possible cause as well as suitable interventions. Additionally, the objective measurement of temporo-spatial gait parameters under dual task conditions may detect deficits in cognitive function. Several interventions have been shown to have favourable effects on gait stability and the occurrence of falls. Proprioceptive problems can be partially compensated for by wearing special shoes. Also, different movement exercises such as Tai Chi Chuan, Jaques-Dalcroze eurhythmics and social dancing are associated with better balance and gait safety, and a reduction of falls.

    Over the past few decades, the knowledge on genetic defects causing mental retardation has dramatically increased. In this review, we discuss the importance of balanced chromosomal translocations in the identification of genes responsible for mental retardation. We present a database-search guided overview of balanced translocations identified in patients with mental retardation. We divide those in four categories: (1) balanced translocations that helped to identify a causative gene within a contiguous gene syndrome, (2) balanced translocations that led to the identification of a mental retardation gene confirmed by independent methods, (3) balanced translocations disrupting candidate genes that have not been confirmed by independent methods and (4) balanced translocations not reported to disrupt protein coding sequences. It can safely be concluded that balanced translocations have been instrumental in the identification of multiple genes that are involved in mental retardation. In addition, many more candidate genes were identified with a suspected but (as yet?) unconfirmed role in mental retardation. Some balanced translocations do not disrupt a protein coding gene and it can be speculated that in the light of recent findings concerning ncRNA's and ultra-conserved regions, such findings are worth further investigation as these potentially may lead us to the discovery of novel disease mechanisms.

  17. Tax balance in agribusiness as a type of special balance

    2015-01-01

    Full Text Available The tendency of continuous compounding of business processes inevitably leads to application of increasingly complex instruments for the purposes of financial reporting in agribusiness. In this system the existential place and role of individual elements that alter the existing and acquire new functions comes into question. Balancing implies a regulated and consistent system in which every change leads to the creation of new relations and changing already established relationships. In this regard, in this paper we will focus on the place and role of tax balance in the group of special balances in agribusiness, as a very significant group of accounting instruments. Displaying information for users and situations in which they are used, balances gain their place in this classification. For the purposes of applying financial instruments, referring primarily to balances in agribusiness, it is necessary to know the way of their classification according to their functions. From this aspect, tax balance in agribusiness is a specific report, both in terms of its formal and material structure, which gives it the basis to belong to ordinary as well as special types of balances in agribusiness.

    The concept and difficulties of work-life balance are not unique to surgeons, but professional responsibilities make maintaining a work-life balance difficult. Consequences of being exclusively career focused include burn out, physical, and mental ailments. In addition, physician burn out may hinder optimal patient care and incur significant costs on health care in general. Assessing current uses of time, allocating goals catered to an individual surgeon, and continual self-assessment may help balance time, and ideally will help prevent burn out.

    The objectives of this paper are to define the scope of global population growth within the uncompromising everyday realities of technology, economies, and politics and to demonstrate the intimate between the human population problem and the increasing problem of Nature's destruction. It is hoped that the human species will come to its sense in time to create an adequate standard of living of all of its members in peace and environmental balance. The number of people the world can support is considered in terms of 1) the provision for a standard of living adequate for everyone's health and wellbeing, 2) consideration for wildlife and nature, and 3) reliance on existing levels of technology and politics. Standards of living are suggested for the affluent and the austere. The focus on the discussion is on standards of living, global carrying capacity, the imperatives of population control and respect for nature, humans versus wildlife, and the need for a universal declaration of respect for nature. Carrying capacity is determined by total land area, cultivated land area, forest land area, cereals (grain), and wood. Use per capita of each of the 5 essentials is determined for the affluent or austere standard of living. An affluent standard means that world population would be limited to 2 billion, which is 50% of the current population. An austere standard of living means a limit of 3 billion, or 33% less than the existing population. The unfortunate reality is that today's total population of 4.5 billion is increasing at an annual rate of 1.9% and is not expected to level off until it has increased 3 times. This population growth occurs at the expense of wildlife. Of the total terrestrial animal biomass, humans constitute 4% and domestic livestock 15%, which, in 40 years, will reach a combined 40% and lead to more species extinction. One species of bird or mammal will become extinct for each increase of 220 million people, which happens every 3 years. The solution is

    Recent years have seen a growing interest in inhibitory interneurons and their circuits. A striking property of cortical inhibition is how tightly it balances excitation. Inhibitory currents not only match excitatory currents on average, but track them on a millisecond time scale, whether they are caused by external stimuli or spontaneous fluctuations. We review, together with experimental evidence, recent theoretical approaches that investigate the advantages of such tight balance for coding and computation. These studies suggest a possible revision of the dominant view that neurons represent information with firing rates corrupted by Poisson noise. Instead, tight excitatory/inhibitory balance may be a signature of a highly cooperative code, orders of magnitude more precise than a Poisson rate code. Moreover, tight balance may provide a template that allows cortical neurons to construct high-dimensional population codes and learn complex functions of their inputs.

    pleasure of eating it. The latter, which is similar to food reward, is determined primarily by the state of emptiness of the gut and food liking related to the food's sensory qualities and macronutrient value and the individual's dietary history. Importantly, energy density adds value because energy dense foods are less satiating kJ for kJ and satiation limits further intake. That is, energy dense foods promote energy intake by virtue (1) of being more attractive and (2) having low satiating capacity kJ for kJ, and (1) is partly a consequence of (2). Energy storage is adapted to feast and famine and that includes unevenness over time of the costs of obtaining and ingesting food compared with engaging in other activities. However, in very low-cost food environments with energy dense foods readily available, risk of obesity is high. This risk can be and is mitigated by dietary restraint, which in its simplest form could mean missing the occasional meal. Another strategy we discuss is the energy dilution achieved by replacing some sugar in the diet with low-calorie sweeteners. Perhaps as or more significant, though, is that belief in short-term energy balancing (the energy depletion model) may undermine attempts to eat less. Therefore, correcting narratives of eating to be consistent with biological reality could also assist with weight control.

    In this work the electronic properties and the composition of the three layers (diffusive, catalytic and outermost) are studied separately. In the first part, an anomalous behaviour of the photoemission peaks from the diffusive layer has been evidenced and correlated with the macroscopic electronic conductivity. In the second part, the electronic properties of the PT clusters are compared with the macroscopic electron conductivity. In the second part, the electronic properties of the PT clusters are compared with those of PT bulk, as a function of thermal treatment and after half-cell measurements. A correlation of the binding energy, asymmetry and width of the peaks with the different status of the metal has been attempted. [Italian] Il lavoro consiste di due parti: l'una dedicata allo studio delle caratteristiche dello strato di supporto e diffusivo, l'altra allo studio dello strato catalizzatore.

    Catalytic premixed burners for domestic boiler applications were developed with the aim of achieving a power modularity from 10 to 100% and pollutant emissions limited to NO{sub x} (<)75 ppmv, CO(<)100 ppmv, HC(<)10 ppmv. The catalyst played a strategic role in reducing the CO and HC emissions, particularly when operating at superficial heat power lower than 800 kw/m{sup 2}, where the combustion took place entirely inside the burner heating it to incandescence and allowing a decrease in the flame temperature and NO{sub x} emissions. Such results were confirmed through further tests carried out in a commercial industrial-scale boiler equipped with the conical panels. All the results, by varying the excess air and the heat power employed, are presented and discussed.

Tutti i risultati, al variare dell'eccesso d'aria e della potenza termica impiegata, vengono presentati e discussi.

L’analisi campionaria effettuata con il metodo PRUO su casi afferenti ai DRG della DGR 864/2002 caratterizzati da livelli di severità minimi evidenzia una proporzione di ricoveri inappropriati superiore a quella determinata tramite i metodi basati sulla SDO. Tale differenza è verosimilmente dovuta al ruolo del valore delle soglie percentuali di accettabilità individuate dalla Regione Lazio per ciascun DRG: le quote di ricoveri che eccedono tali soglie sono considerate inappropriate.

    This article deals with the design of a low-cost balancing system which consist of battery balancing units, accumulator pack units and coordinator unit with interface for higher level of battery management system. This solution allows decentralized mode of operation and the aim of this work is implementation of controlling and diagnostic mechanism into an electric scooter project realized at Technical university of Ostrava. In todays world which now fully enjoys the prime of electromobility, off-grid battery systems and other, it is important to seek the optimal balance between functionality and the economy side of BMS that being electronics which deals with secondary cells of batery packs. There were numerous sophisticated, but not too practical BMS models in the past, such as centralized system or standalone balance modules of individual cells. This article aims at development of standalone balance modules which are able to communicate with the coordinator, adjust their parameters and ensure their cells safety in case of a communication failure. With the current worldwide cutting cost trend in mind, the emphasis was put on the lowest price possible for individual component. The article is divided into two major categories, the first one being desing of power electronics with emphasis on quality, safety (cooling) and also cost. The second part describes development of a communication interface with reliability and cost in mind. The article contains numerous graphs from practical measurements. The outcome of the work and its possible future is defined in the conclusion.

La Mostra, inoltre, ha giocato un ruolo chiave nella ridefi nizione del ruolo artistico internazionale di Venezia all’interno dell’organizzazione fascista. Poiché la Mostra ha avuto luogo durante l’anno di intervallo tra le due Biennali e ha ricevuto poco sostegno da parte delle istituzioni governative, è generalmente trascurata nella letteratura sul periodo. Tuttavia, sulla base di documentazione archivistica inedita e della ricostruzione digitale di queste sale internazionali, questo saggio sostiene che la “Mostra dei Quarant’anni” è fondamentale per la nostra comprensione della storia della Biennale e delle politiche culturali dello stato fascista.

    2016-01-01

    New experimental results on bacterial growth inspire a novel top-down approach to study cell metabolism, combining mass balance and proteomic constraints to extend and complement Flux Balance Analysis. We introduce here Constrained Allocation Flux Balance Analysis, CAFBA, in which the biosynthetic costs associated to growth are accounted for in an effective way through a single additional genome-wide constraint. Its roots lie in the experimentally observed pattern of proteome allocation for metabolic functions, allowing to bridge regulation and metabolism in a transparent way under the principle of growth-rate maximization. We provide a simple method to solve CAFBA efficiently and propose an "ensemble averaging" procedure to account for unknown protein costs. Applying this approach to modeling E. coli metabolism, we find that, as the growth rate increases, CAFBA solutions cross over from respiratory, growth-yield maximizing states (preferred at slow growth) to fermentative states with carbon overflow (preferr...

    2013-12-01

    Full Text Available Data load balancing is one of the key problems of big data technology. As a big data application, Hadoop has had many successful applications. HDFS is Hadoop Distributed File System and has the load balancing procedure which can balance the storage load on each machine. However, this method cannot balance the overload rack preferentially, and so it is likely to cause the breakdown of overload machines. In this paper, we focus on the overload machines and propose an improved algorithm for balancing the overload racks preferentially. The improved method constructs Prior Balance List list which includes overload machines, For Balance List list and NextForBalanceList list by many factors and balances among the racks selected from these lists firstly. Experiments show that the improved method can balance the overload racks in time and reduce the possibility of breakdown of these racks

    Full Text Available Veinte años han pasado desde que se dieron los sucesos en la República Democrática Alemana (RDA que llevarían, en noviembre de 1989, a la caída del muro de Berlín y a la reunificación de Alemania el 3 de octubre de 1990. El proceso de unificación alemana dio pie en sus comienzos a una optimista visión que, sin embargo, con el paso del tiempo ha cambiado de tal forma que hoy se habla del ‘messogiorno alemán’ para designar a la zona oriental comparándola con la zona deprimida del sur de Italia. Pero la Alemania unificada en el contexto internacional supuso también cambios para la zona occidental que, entre otros, se han traducido en la crisis del sector industrial tradicional y en el desempleo estructural. Así, a la difícil constelación de la situación interna de la Alemania reunificada, se ha adicionado la realidad internacional con una decreciente producción industrial como fenómeno global en todas las viejas naciones industriales y con un proceso de desregularización que significó en Alemania oriental la ‘privatización de toda la sociedad’. En Alemania se han llevado y se están llevando cambios sociales profundos, que no tienen comparación con ningún otro país de las potencias occidentales ni, en el caso de la ex RDA con ningún país del este. Evaluar el proceso de unificación alemana, primera potencia europea y motor del proceso de integración en ese continente, se hace imperante. El presente artículo intenta hacer un diagnóstico parcial de la nueva realidad en la Alemania unificadaa comienzos del siglo XXI.

    Full Text Available Il contributo analizza il dotario of Angelberga (ca. 831-891, moglie dell’imperatore Ludovico II. Angelberga rivestì un importante ruolo politico sia durante il suo matrimonio, sia dopo la morte del marito, e riuscì inoltre a costruire un impressionante patrimonio. Angelberga acquisì infatti un grande numero di beni fondiari, in parte tramite donazioni del consorte e in parte grazie ad acquisizioni personali. Nell’877 l’imperatrice assegnò il suo patrimonio al monastero di San Sisto, da lei fondato a Piacenza. Il contributo esamina in dettaglio l’ubicazione dei beni di Angelberga, dimostrando che gran parte di tali beni era situata in prossimità del corso del fiume Po: tale collocazione consentiva il controllo delle principali vie di comunicazione del regno d’Italia. Inoltre le proprietà di Angelberga si trovavano per lo più in aree controllate dai Supponidi, la potente famiglia di origine dell’imperatrice. Il saggio conclude che la costruzione del patrimonio di Angelberga, e del monastero che ne derivò, dimostra una convergenza di interessi economici e politici tra il potere regio e le aristocrazie locali rappresentate dalla potente famiglia d’origine dell’imperatrice.

    This study analyzes the dower of Angelberga (ca. 831-891, wife of emperor Louis II. Angelberga played a significant political role during her marriage and after her husband’s death; moreover she accumulated an impressive patrimony. Angelberga gathered a great number of landed properties, partly through donations from her husband and partly thanks to personal acquisitions. In 877 the empress left her wealth to the monastery of St. Sisto, which she had founded in Piacenza. This article offers a detailed analysis of the location of Angelberga’s properties, showing that most of these properties were situated in the proximity of the Po river: this location allowed for the control of the main communication routes of the Italic Kingdom.

    In karate, balance control represents a key performance determinant. With the hypothesis that high-level athletes display advanced balance abilities, the purpose of the current study was to quantitatively investigate the motor strategies adopted by elite and non-elite karateka to maintain balance control in competition. The execution of traditional karate techniques (kihon) in two groups of elite Masters (n = 6, 31 ± 19 years) and non-elite Practitioners (n = 4, 25 ± 9 years) was compared assessing body center of mass (CoM) kinematics and other relevant parameters like step width and angular joint behavior. In the considered kihon sequence, normalized average CoM height was 8% lower (p < 0.05), while CoM displacement in the horizontal direction was significantly higher in Masters than in Practitioners (2.5 vs. 1.9 m, p < 0.05), as well as CoM average velocity and rms acceleration (p < 0.05). Step width was higher in Masters in more than half of the sequence steps (p < 0.05). Results suggest that elite karateka showed a refined dynamic balance control, obtained through the increase of the base of support and different maneuvers of lower limbs. The proposed method could be used to objectively detect talented karateka, to measure proficiency level and to assess training effectiveness.

    Full Text Available Infectious diseases continue to represent an important preventive and clinical problem especially in the light of the emergence of new pathogens, of the return of infrequent pathogens and of the increased risk of infective pathologies associated with migratory flow. Another critical point is represented by the possible insurgence of infections due to agents used in bioterrorism. More than ever it is indispensable for our country to define a network of structures able to give an organized response to these relevant problems both in terms of prevention and assistance. It is therefore important to define a protocol for clinical microbiology on a national basis that responds to different levels of activity. Keeping in mind that the fundamental objectives of microbiology are: - diagnosis of infective diseases - determination of resistance to antimicrobic drugs as a valid instrument to allow the clinician to proceed with specific treatment - control of infection spreading in the sanitary structures (hospital infections - to develop front line defence in new infections and bioterrorism, in collaboration with the department of prevention - to be a reference centre for specific training The principals on which one must base the reorganization are essentially three: 1. to configurate the microbiology service on the basis of real needs of the local population 2. to give qualitatively optimal results in real time 3. supporting “good clinical practice” to assure adequate patient results and acceptable costs for the regionale sanitary system (SSR The organization of microbiology should therefore foresee a microbiology department, structured on a provincial basis or a vast area including a structured centralized complex with peripheral structures (even simplified. This must integrate actively with the department of prevention in regard to the dynamics of infectious diseases in the territory and with the Division of Infectious Diseases (where this exists. In parallel an active interaction with research structures (IRCCS and University present in the territory to enable the coordinated implementation of the guidelines of research and its relapse on diagnostic exams. Keeping in mind that the quality of diagnostic performance is closely linked to the professional experience of the operators it is good practice centralizing some diagnostic procedures by identifying a reference centre. In a regional network organized in this way it is important to include a coordinating structure, since it is necessary to activate a complete level of communication, information exchange, activity planning, and complete problem solving.

    Catherine Sophie Dimitroulias

    2013-01-01

    Full Text Available Sostanziale, reale, la parità di genere è un valore universale, principio e diritto uma-no, proclamato ed imposto da strumenti vincolanti a livello internazionale ed europeo, che ne richiedono l‟effettiva promozione in tutti i campi, stabiliscono il carattere univer-sale e non negoziabile dei diritti umani, inclusa la parità di genere e i diritti delle donne, ed escludono nel modo più assoluto che si possano invocare usanze o tradizioni etniche, culturali o religiose per ostacolarne l‟esercizio. Questo contributo ricorda la ricchezza e i limiti di questo «acquis» internazionale ed europeo in materia di parità di genere, oggi messa seriamente a rischio, sottolineando, a tal proposito, la recente mobilitazione del movimento delle donne e della società civile. L‟attenzione è posta sul diffondersi del re-lativismo culturale, sul sorgere del fondamentalismo religioso e sui tentativi in costante aumento e spesso violenti di distruggere i principi democratici e il ruolo della legge, che si manifestano a livello internazionale, europeo, nazionale e locale, minacciando l‟uguale godimento dei diritti umani da parte delle donne e degli uomini, delle ragazze e dei ragazzi; la propensione ad adottare misure di governance economica di carattere e-sclusivamente monetarista e ad ignorare la dimensione sociale della crisi economica e finanziaria globale, in crescita anche in Europa, a discapito della coesione sociale e del-la crescita. Il contributo sostiene l‟urgente richiesta della società civile che tutti gli attori della comunità internazionale si oppongano con forza a queste tendenze e tentativi, e adottino un‟agenda anti-crisi che sia giusta socialmente e rispettosa dei diritti fonda-mentali, specialmente dei diritti delle donne, così che l‟acquisizione universale nei dirit-ti umani sia salvaguardata e si promuova l‟applicazione degli strumenti sopraindicati.

    The prevalence of sustaining a fall is particularly high in children. Deficits in postural control and muscle strength are important intrinsic fall risk factors. Thus, the purpose of this study was to investigate the impact of balance training (BT) followed by detraining on postural control, plantar flexor strength, and jumping height in prepubertal children. Thirty grade 1 school children participated in this study and were assigned to either an intervention class (INT, n = 15, age 6.7 ± 0.5 years) or a control class (n = 15, age 6.6 ± 0.5 years). The INT participated in 4 weeks of BT (3 per week) integrated in their physical education lessons. Pre, post, and follow-up tests included the measurements of postural sway on a balance platform, maximal torque and rate of force development of the plantar flexors on an isokinetic device, and jumping height on a force platform. The significance level was set at p training resulted in tendencies in terms of small to medium interaction effects yet not statistically significant improvements in postural sway (f = 0.14; p > 0.05), force production of the plantar flexors (f = 0.18; p> 0.05), and jumping height (f = 0.25; p> 0.05). Immaturity of the postural control system and deficits in attentional focus during practice of balance exercises could be responsible for the nonsignificant findings in this study. Thus, other training regimen (e.g., resistance training) should be applied alone or in combination with BT, which may have the potential to promote balance and strength in children.

    Full Text Available In criminal proceedings, the victim of the crime plays a central role as he may check and solicit the public prosecutor in exercising the criminal action and he can exercise himself a civil action within the criminal proceedings. The role of the crime victim is now even more important as the recent rulings of the Italian Supreme Court of November 11, 2008, have broadened the object of the proof that the plaintiff has to allege in order to determine the damage, which cannot be deemed to be in re ipsa in the very fact of the commission of the criminal offence, but has to be actually proved by the damaged person, even if by natural presumption.

    Full Text Available This article surveys studies on universally balanced properties of cooperative games defined in a succinct form. In particular, we focus on combinatorial optimization games in which the values to coalitions are defined through linear optimization programs, possibly combinatorial, that is subject to integer constraints. In economic settings, the integer requirement reflects some forms of indivisibility. We are interested in the classes of games that guarantee a non-empty core no matter what are the admissible values assigned to the parameters defining these programs. We call such classes universally balanced. We present characterization and complexity results on the universally balancedness property for some classes of interesting combinatorial optimization games. In particular, we focus on the algorithmic properties for identifying universally balancedness for the games under discussion.

    Actuator/sensor locations and balanced representations of linear systems are considered for a given set of controllability and observability grammians. The case of equally controlled and observed states is given special attention. The assignability of grammians is examined, and the conditions for their existence are presented, along with several algorithms for their determination. Although an arbitrary positive semidefinite matrix is not always assignable, the identity grammian is shown to be always assignable. The results are extended to the case of flexible structures.

    New experimental results on bacterial growth inspire a novel top-down approach to study cell metabolism, combining mass balance and proteomic constraints to extend and complement Flux Balance Analysis. We introduce here Constrained Allocation Flux Balance Analysis, CAFBA, in which the biosynthetic costs associated to growth are accounted for in an effective way through a single additional genome-wide constraint. Its roots lie in the experimentally observed pattern of proteome allocation for metabolic functions, allowing to bridge regulation and metabolism in a transparent way under the principle of growth-rate maximization. We provide a simple method to solve CAFBA efficiently and propose an “ensemble averaging” procedure to account for unknown protein costs. Applying this approach to modeling E. coli metabolism, we find that, as the growth rate increases, CAFBA solutions cross over from respiratory, growth-yield maximizing states (preferred at slow growth) to fermentative states with carbon overflow (preferred at fast growth). In addition, CAFBA allows for quantitatively accurate predictions on the rate of acetate excretion and growth yield based on only 3 parameters determined by empirical growth laws. PMID:27355325

    The cone contrasts carrying different dimensions of color vision vary greatly in magnitude, yet the perceived contrast of color and luminance in the world appears similar. We examined how this perceptual balance is adjusted by adaptation to the contrast in images. Observers set the level of L vs. M and S vs. LM contrast in 1/f noise images to match the perceived strength of a fixed level of luminance contrast. The perceptual balance of color in the images was roughly consistent with the range of contrasts characteristic of natural images. Relative perceived contrast could be strongly biased by brief prior exposure to images with lower or higher levels of chromatic contrast. Similar adaptation effects were found for luminance contrast in images of natural scenes. For both, observers reliably chose the contrast balance that appeared correct, and these choices were rapidly recalibrated by adaptation. This recalibration of the norm for contrast could reflect both changes in sensitivity and shifts in criterion. Our results are consistent with the possibility that color mechanisms adjust the range of their responses to match the range of signals in the environment, and that contrast adaptation plays an important role in these adjustments.

    [Purpose] This study investigated efficacy of virtual reality (VR)-based balance training on enhancing balance and postural reactions of adults as a low-cost new modality compared to the established Biodex Balance System (BBS). [Subjects] Thirty normal adults of both genders were divided randomly into two equal-sized experimental groups of 15: BBS balance training and VR balance training. [Methods] The training programmes were conducted in 12 sessions, three 15-min sessions per week. The Nintendo(®) Wii Fit Plus (NWFP) and its balance board were used to train of the VR group. Each participant answered a questionnaire concerning usability, enjoyment, balance improvement, and fatigue at the end of the training programs. [Results] The study found a significant increase the measure of mean overall balance (OLB) in both groups. No significant difference was found between the groups, but a significant decrease in the mean balance-test time was found for both groups, with no significant difference between the two training methods. The VR programme was rated highly enjoyable by 81.8% of the group. [Conclusion] The Wii Fit Plus system with the balance board as a new VR balance-training technique, can be considered an effective and enjoyable tool for the training of adults' body balance.

    In tale ottica diventa allora interessante indagare le forme che le parole di un'opera assumono, per valutare quanto la parola scritta ricalchi o meno la parola piena, anche nel suo rapporto con il fruitore diretto, il lettore, che assume un ruolo che, forzando i termini del paragone, potremmo definire quasi di psicoanalista, in quanto si mette nella posizione di ascoltatore e interprete della parola. E così come per lo psicoanalista, la sua funzione sarà quella di riempire i blanks, gli spazi bianchi di cui parla Wolfgang Iser, alla ricerca dell'interpretazione. In alcuni casi, lo stesso atto della scrittura sarà un tentativo di far assumere alla parola quella intersoggettività che la rende piena, in altre invece spetterà al lettore-psicoanalista lo sforzo di riempire di significato i blanks, gli spazi vuoti della parola perché, come suggerisce Roland Barthes, «tutta la moneta logica è negli interstizi». Così diviene interessante l'utilizzo di una teoria critica che, attraverso gli strumenti della psicoanalisi lacaniana e dei paradigmi di Iser, tenti un'analisi comparata dei diari di Tommaso Landolfi e del romanzo pseudo-autobiografico W ou le souvenir d'enfance di Georges Perec. In queste due opere infatti i confini tra i ruoli di autore, personaggio e lettore sono molto sfumati e la scrittura è scissa in due parti: una più immediatamente indagabile, l'altra invece tentativo di narrare il bianco che accompagna la memoria e la scrittura e che, attraverso questo metodo, il critico può tentare di riempire.

    Pyatt, G

    1992-01-01

    Pakistan is a country whose economic growth is surprising in light of its social indicators. The aim of this article is to examine why conditions are such and to develop a framework for understanding the issues as an aid to redesigning policies. 5 sections are devoted to a summary of the main findings, the diagnosis of development and the impact on social sectors, a proposal for balanced development, and implications for policy changes. A sound macro economic context is needed with reforms economically in price and incentive systems, institutionally, and in the law and order sector. Public administration needs to be improved and individual opportunities need to be expanded. Internal security needs to be secured, so that law and order are restored. Economic growth has been high between 1960 and 1988, due to exploitation of natural resources and cheap unskilled labor, expansion of irrigated land, and growth of the unregulated informal sector. The major constraints on economic growth will come from a lack of fiscal discipline. 40% of government revenues are consumed by the military and 20% for servicing debt. Other constraints are the population growth rate in excess of 3%/year, an urban bias in allocation of resources, neglected primary education, and gender bias in education. There has been little incentive for provincial governments to balance budgets, and civil service has become disorganized. Balanced development entails recognizing human capital, natural resources, and infrastructure; accepting the status quo; and creating and maintaining an institutional framework to correct market failures and promote individual opportunities. The environmental polluter must pay. Income must be increased through higher wages, increasing the demand for labor, and transfers to households in the form of food rations, schooling, and medical care. Investment in women will increase household earnings, and improve living conditions and the health of themselves and their children

    Full Text Available Las ligas deportivas dependen del equilibrio competitivo entre los equipos para ser atractivas para los espectadores, de ahí la aparición del balance competitivo. Por ello, las distintas ligas deportivas han adquirido diferentes formatos que determinarán su competitividad. El objetivo de este artículo es comparar el balance competitivo de la NBA y las principales ligas europeas, teniendo en cuenta la NBA en su conjunto y cada una de sus conferencias de forma independiente. Las variables utilizadas para medir el balance competitivo han sido el índice Hirschman-Herfindal y las ratios C5 y C8. Los resultados muestran un mejor balance competitivo de la NBA en conjunto respecto a las ligas europeas, sin embargo estas diferencias desaparecen al analizar las conferencias de forma independiente. Se concluye que al tener en cuenta cada una de las conferencias de forma independiente, con una estructura más similar a las ligas europeas, se presenta un balance competitivo parecido bajo los indicadores utilizados. Sin embargo, la NBA incluye limitaciones en la competición que siguen favoreciendo la posibilidad de que sea más atractiva para el espectador.

Sin embargo, los resultados de tales representaciones entendidas como acciones colectivas –y por tanto comunes- no siempre explican los valores que desde lo simbólico partiendo del sujeto constituyan un estatus diferente de lo público en los procesos de territorialización.

    Flux balance analysis is a common method for predicting steady-state flux distributions within metabolic networks, accounting for the growth demand for the synthesis of a predefined set of essential biomass precursors. Ignoring the growth demand for the synthesis of intermediate metabolites required for balancing their dilution leads flux balance analysis to false predictions in some cases. Here, we present metabolite dilution flux balance analysis, which addresses this problem, resulting in improved metabolic phenotype predictions.

    Purpose of this work is to evaluate the effectiveness and role of CT in blunt diaphragmatic injuries by reviewing our 8-year experience. It is reviewed the preoperative CT findings of 35 patients with surgically confirmed diaphragmatic rupture. Surgical repair was performed in the acute setting (within 12 hours of trauma) in 22 cases, and late (8 months-5 years) in 13 cases. Twenty-eight patients (80%) were examined with conventional CT and 7 (20%) with Helical CT. Of the 13 patients examined long after trauma, the left hemi diaphragm was ruptured in 12 cases (with visceral herniation in 4), and the right hemi diaphragm in 1, with no herniation. The diaphragmatic rent was found in the dome (15 cases, 43%), muscolotendinous junction (11 cases, 31%), muscular portion (8 cases, 23%), and at the muscular attachments on the ribs (1 case, 3%). As for the site of diaphragmatic injury, CT never depicted the diaphragmatic rent in the dome and at the muscolotendinous junction (74%), not even with thin slices and the multiplanar Helical technique. CT detected indirect signs of injury at the muscular portion (23%), showing the injury site directly in the case with diaphragmatic avulsion (3%). CT is a reliable tool in the diagnosis of suspected diaphragmatic injury in the acute trauma setting. Long after trauma, CT performs poorly because it depicts the diaphragmatic rent only in some peripheral traumas. Helical CT has greater diagnostic potentials, but the injury site and type do affect its capabilities.

    The authors investigated the accuracy of a new US (ultrasound) investigation technique, called retrograde cystography US, in the early diagnosis and staging of vesicoureteral reflux. 5 patients, aged 3 months to 10 years, suffering from hydronephrosis and/or pyelonephritis, were examined using retrograde cystography US followed by conventional retrograde cystography. Retrograde cystography US consists in the transcatheter introduction of a contrast agent into the bladder and a subsequent color Doppler examination to show or exclude the presence of reflux. Superpubic scanning of bladder, ureters and pyelocaliceal cavity was performed after echo contrast agent introduction to assess the reflux grade. US was performed with an Esaote AU 590 asynchronous scanner with a 3.5 MHz convex probe. The total agreement of conventional and US findings seems to confirm the importance of the US method for the diagnosis and staging of vesicoureteral reflux. [Italian] Sono stati reclutati 5 pazienti con eta' compresa fra 3 mesi e 10 anni affetti da idrofrenosi e/o pielofrenite, per valutare l'accuratezza di una nuova metodica d'indagine, l'ecocistografia retrograda nella diagnosi e stadiazione del reflusso vescico-ureterale. E' stata eseguita ecocistigrafia retrograda e successivamente cistografia retrograda di controllo. L'ecocistografia retrograda consiste nell'introduzione trans-catetere di un mezzo di contrasto Levovist nella vescia e successivamente controllo con eco color Doppler per evidenziare o escludere la presenza del reflusso. Le indagini ecografiche sono state condotte con un apparecchio AU 590 Asyncronus con sonda convex da 3.5 MHz.

Con el fin de evitar el fraude y contra el pago anual de una suma de dinero, el clero napolitano fue de hecho llamado a pagar los impuestos sobre géneros de amplio consumo. El uso de los fondos de estas «franquicias» pronto se convirtió en objeto de disputa dentro del mismo clero. El Papado rápidamente asumió un papel clave, tanto como fuente de legitimidad de la exacción, cuanto como beneficiario del dinero de las «franquicias» del clero de Nápoles, que fue destinado a la Fabbrica di San Pietro en Roma.The aim of this article is to analyze the construction of mechanisms of exemption of the clergy from excise taxes in the city of Naples between XVIth and XVIIth centuries. In order to avoid fraud and against annual repayment of a sum of money, the Neapolitan clergy was in fact called upon to pay the taxes on certain consumer goods. The use of the proceeds of this «franchigie» soon became the subject of dispute among the clergy.

    Rezende, Pedro A. D.

    This article aims to share some major lessons learned from the pioneering experience in Brazil with the world's first full national implementation of universal electronic voting. Differing notions of security, and their "collateral entanglements", appear to play a key role and are contrasted in Brazil's pioneering electronic voting saga. After an introduction, we puzzle through what election security may mean. We elaborate on how technological innovations may affect the underlying risks, their nature, corrections and balance. Then we describe some ways in which innovations have been deployed and validated, and how the results are being perceived, before some closing remarks.

    Characterizing the influence of network properties on the global emerging behavior of interacting elements constitutes a central question in many areas, from physical to social sciences. In this article we study a primary model of disordered neuronal networks with excitatory-inhibitory structure and balance constraints. We show how the interplay between structure and disorder in the connectivity leads to a universal transition from trivial to synchronized stationary or periodic states. This transition cannot be explained only through the analysis of the spectral density of the connectivity matrix. We provide a low-dimensional approximation that shows the role of both the structure and disorder in the dynamics.

    @@ Changes in the content of European balance constitute the biggest difference between the economic integration model and its predecessors. Armament, territory and resources were considered as key factors for enhanced strength and sustained power parity with other nations. Transition to economic integration has however entailed decoupling of the two. Enhanced national strength now aims instead at power parity and shared power based on common European interests and inter-dependency rather than at weakening other nations. As a result, state relations there are moving toward fusion and convergence.

    2016-04-01

    Full Text Available The concept of full compensation against the resultant shaking forces and moments for arbitrary robots using a single active dynamic balancing mechanism is first addressed. And the application principle and general balancing conditions of the active dynamic balancing mechanism are presented. With the purpose of providing detailed description of these problems, a compact planar 3-degree-of-freedom active dynamic balancing mechanism is proposed. The active balancer is composed of three independent rotating bars with their respective actuators. The rotations of the three bars could change their center of gravity positions and then generate balancing forces for the unbalanced robots. Moreover, the changing of the angular acceleration of the bars can also generate a dynamic torque to balance the shaking moment. In order to present more detail of the balancing theory, the structure and kinematic and dynamic analysis of the proposed balancing mechanism are given. Finally, numerical examples illustrate the effectiveness of the proposed three-rotating-bar balancer.

Secondo l’Organizzazione Mondiale della Sanità la qualità di vita (QdV è “la personale percezione che un individuo ha della propria posizione nella vita, nel contesto di una cultura e di un insieme di valori nei quali egli vive, anche in relazione ai propri obiettivi, aspettative e preoccupazioni”. Numerosi sono gli strumenti psicometrici progettati per misurare in ambito sanitario l’impatto dell’erogazione di interventi clinico-assistenziali sulla QdV degli utenti, tuttavia poca attenzione si è posta sul ruolo di alcuni predittori - socio-demografici, clinici ed economico-sanitari - durante la degenza ospedaliera. Obiettivi. Accertare l’esistenza ed il tipo di associazione tra alcuni predittori e la variazione della QdV alla dimissione; esaminare i possibili risvolti per la pratica infermieristica. Metodi. Lo studio, condotto presso la struttura ospedaliera del polo universitario di Milano, ha somministrato all’ingresso e alla dimissione dei pazienti lo strumento psicometrico EuroQol-5D. Per valutare l’impatto del trattamento sulla QdV è utilizzato il test ?2, mentre per misurare significatività e rilevanza dei predittori è stato creato un modello di regressione logistica multipla. Risultati. L’erogazione di un trattamento clinico durante il ricovero migliora la QdV percepita (p < 0.001. La proporzione di esiti positivi nei trattamenti medici rispetto a quelli chirurgici è superiore (p < 0.05, così come quella nei ricoveri urgenti (p < 0.01.

    Directory of Open Access Journals (Sweden)

    Ruchir A Khandelwal

    Full Text Available A central focus in studies of microbial communities is the elucidation of the relationships between genotype, phenotype, and dynamic community structure. Here, we present a new computational method called community flux balance analysis (cFBA to study the metabolic behavior of microbial communities. cFBA integrates the comprehensive metabolic capacities of individual microorganisms in terms of (genome-scale stoichiometric models of metabolism, and the metabolic interactions between species in the community and abiotic processes. In addition, cFBA considers constraints deriving from reaction stoichiometry, reaction thermodynamics, and the ecosystem. cFBA predicts for communities at balanced growth the maximal community growth rate, the required rates of metabolic reactions within and between microbes and the relative species abundances. In order to predict species abundances and metabolic activities at the optimal community growth rate, a nonlinear optimization problem needs to be solved. We outline the methodology of cFBA and illustrate the approach with two examples of microbial communities. These examples illustrate two useful applications of cFBA. Firstly, cFBA can be used to study how specific biochemical limitations in reaction capacities cause different types of metabolic limitations that microbial consortia can encounter. In silico variations of those maximal capacities allow for a global view of the consortium responses to various metabolic and environmental constraints. Secondly, cFBA is very useful for comparing the performance of different metabolic cross-feeding strategies to either find one that agrees with experimental data or one that is most efficient for the community of microorganisms.

    During the last decade of the 20th Century, diverse campaigns for measuring the atmospheric energy balance were performed in downtown Mexico City (School of Mines and Preparatory School No. 7), in the southern suburbs (University Reserve) and in the surrounding rural areas (Plan Texcoco), in addition to a campaign carried out in 1985 in the Tacubaya district, a suburban western peripheral site. The objective was to obtain data for a better understanding of the climatic alterations due to urbanization, particularly to describe the role that the modification of the natural ground cover has played as a result of paving and the construction of urban canyons. In this paper, a review of these campaigns is presented. Energy partitioning in some areas (Tacubaya and Preparatory School No.7) is similar to that observed in urban centers of middle latitudes, whereas the major contrast was observed between Texcoco, with maximum energy consumption through evaporation, and School of Mines, where the latent heat is as low as in a desert. From the values of the correlations among the different components of energy balance, it may be possible to attempt the modeling of the diverse components of energy balance by means of regression equations starting from the net radiation. Those same coefficients distinguish the type of environment: urban, suburban or rural. [Spanish] Las primeras mediciones de balance energetico en la Ciudad de Mexico se realizaron en 1985 en un suburbio al poniente de la ciudad (el observatorio de Tacubaya).

    Full Text Available Domesticated at the same time as the first cereals and other carbohydrate-rich crops, legumes have maintained close ties with these in all aspects of human life: in the land, traditions, and as food for man or animal feed. However, in modern farming they are only considered to be second class crops, in spite of continuous calls for their use in balanced diets and in crop rotations to increase soil fertility by fixing atmospheric nitrogen, avoiding excess use of synthetic fertilizers. Because of their high protein content they were known as “the poorman’s meat”. Moreover, their ability to fertilize soil was greatly valued by ancient agronomists since Greek and Roman times. Rather than focusing on the technical aspects of legumes, the present article considers the relationship between man and legumes from different perspectives, including their role in the History of Science, being protagonists of fundamental studies such as those carried out by Mendel, Galton and Johannsen, as well as the first description of a QTL.Domesticadas a la par que los primeros cereales y otros cultivos ricos en carbohidratos, compañeras inseparables de ellos en la tierra, en las costumbres, en la mesa y en el pesebre, en la agricultura moderna las leguminosas no son, sin embargo, más que secundarias o terciarias, a pesar de las llamadas a su consumo en dietas equilibradas y a la necesidad de su inclusión en la “alimentación” del suelo, es decir, en las rotaciones que incrementen la fertilidad del mismo de forma natural.

    Full Text Available Battery management systems (BMS are a key element in electric vehicle energy storage systems. The BMS performs several functions concerning to the battery system, its key task being balancing the battery cells. Battery cell unbalancing hampers electric vehicles’ performance, with differing individual cell voltages decreasing the battery pack capacity and cell lifetime, leading to the eventual failure of the total battery system. Quite a lot of cell balancing topologies have been proposed, such as shunt resistor, shuttling capacitor, inductor/transformer based and DC energy converters. The shuttling capacitor balancing systems in particular have not been subject to much research efforts however, due to their perceived low balancing speed and high cost. This paper tries to fill this gap by briefly discussing the shuttling capacitor cell balancing topologies, focusing on the single switched capacitor (SSC cell balancing and proposing a novel procedure to improve the SSC balancing system performance. This leads to a new control strategy for the SSC system that can decrease the balancing system size, cost, balancing time and that can improve the SSC balancing system efficiency.

    Health care employees are often women, a group that has high degrees of sick leave and perhaps problems attaining occupational balance. However, people think differently about their everyday activities and it is therefore important to take their perceptions into account but occupational balance has not yet been measured in health professionals. The aim was to describe occupational balance in three different samples of health professionals in Sweden. A further aim was to investigate whether occupational therapists (OTs) rate their occupational balance differently from other health professionals. Four hundred and eighty-two health professionals, employees in public dentistry, mental health care and OTs, aged 21-70 years participated. The participants' occupational balance was measured using the occupational balance questionnaire (OBQ). The ratings of occupational balance were similar to earlier studies and did not differ significantly between the samples. The OTs' occupational balance was also similar to that of the other health professionals. The similarities in occupational balance indicate the same difficulties in attaining it. The result highlights the possibility that working people face similar difficulties in achieving occupational balance. Further research is warranted about how to attain it.

It comprises an iPhone with an embedded tri-axial linear accelerometer, custom software to estimate body tilt, a "tactor bud" accessory that plugs into the headphone jack to provide vibrotactile cues of body tilt, and a battery. Five young healthy subjects (24 ± 2.8 yrs, 3 females and 2 males and four subjects with vestibular deficits (42.25 ± 13.5 yrs, 2 females and 2 males participated in a proof-of-concept study to evaluate the effectiveness of the system. Healthy subjects used the system with eyes closed during Romberg, semi-tandem Romberg, and tandem Romberg stances. Subjects with vestibular deficits used the system with both eyes-open and eyes-closed conditions during semi-tandem Romberg stance. Vibrotactile feedback was provided when the subject exceeded either an anterior-posterior (A/P or a medial-lateral (M/L body tilt threshold. Subjects were instructed to move away from the vibration. Results The system was capable of providing real-time vibrotactile cues that informed corrective postural responses. When feedback was available, both healthy subjects and those with vestibular deficits significantly reduced their A/P or M/L RMS sway (depending on the direction of feedback, had significantly smaller elliptical area fits to their sway trajectory, spent a significantly greater mean percentage time within the no feedback zone, and showed a significantly greater A/P or M/L mean power frequency. Conclusion The results suggest that the real-time feedback provided by this system can be used

    Full Text Available El complejo suspensorio del hombro es una estructura sumamente importante, compuesta por un anillo de huesos y tejidos blandos. Las lesiones aisladas de este complejo anatómico son frecuentes y no afectan su estabilidad. La interrupción doble conduce a la inestabilidad de esta estructura y usualmente requiere tratamiento quirúrgico. La triple interrupción, por su parte, es sumamente rara y es encontrada en casos de trauma de alta energía a menudo en asociación con otras lesiones. Se presenta una triple lesión del complejo suspensorio del hombro en un paciente de 46 años de edad, con una fractura de la glenoides, del acromion tipo III de Kuhn y de la coracoides tipo II de Ogawa. En este caso, la fractura del acromion fue tratada con fijación percutánea con alambres de Kirschner, por tener asociado lesiones de partes blandas que contraindicaron la reducción abierta. La fractura de la glenoides y de la apófisis coracoides fueron tratadas conservadoramente. Después de 6 meses de evolución, el paciente tuvo un resultado funcional aceptable, con una abducción de 90 grados, los 30 grados de rotación externa y 70 de rotación interna, además asintomático y consolidación de todas las fracturas. A pesar de ser catalogada de una lesión grave del cinturón escapular y estar asociada a otras lesiones se obtuvo un resultado satisfactorio al final del tratamiento.

  6. Physical Limitations of Empirical Field Models: Force Balance and Plasma Pressure

    2002-06-18

    In this paper, we study whether the magnetic field of the T96 empirical model can be in force balance with an isotropic plasma pressure distribution. Using the field of T96, we obtain values for the pressure P by solving a Poisson-type equation {del}{sup 2}P = {del} {center_dot} (J x B) in the equatorial plane, and 1-D profiles on the Sun-Earth axis by integrating {del}P = J x B. We work in a flux coordinate system in which the magnetic field is expressed in terms of Euler potentials. Our results lead to the conclusion that the T96 model field cannot be in equilibrium with an isotropic pressure. We also analyze in detail the computation of Birkeland currents using the Vasyliunas relation and the T96 field, which yields unphysical results, again indicating the lack of force balance in the empirical model. The underlying reason for the force imbalance is likely the fact that the derivatives of the least-square fitted model B are not accurate predictions of the actual magnetospheric field derivatives. Finally, we discuss a possible solution to the problem of lack of force balance in empirical field models.

    to determine whether it is the presence of women in an organization or the presence of working parents that induce organizations to implement work-family balancing and ORWT measures. We found that workers without children are more often found in jobs that offer more services for the elderly and for childcare. We also show that regarding ORWT, behaviours of women without children are often closer to those of men, but that the presence of children is a major factor in explaining the aspirations of men regarding working time. Few studies have investigated these issues from this angle and it is clear that the presence of children is often more of a determining factor than the fact of being a woman, while women are still clearly more concerned when daycare services or care for the elderly are involved.Los datos que presentaremos proporcionan un retrato de la situación canadiense desde el punto de vista de la organización y de la reducción del tiempo de trabajo (ORTT, así como del lugar de trabajo (oficina, domicilio, etc.. Los datos muestran en qué medida el ORTT puede ser visto por algunos como una solución y por otros como una fuente de dificultades para los problemas de conciliación entre el empleo y la familia o de estrés. Hemos estudiado la situación tanto de los hombres como de las mujeres en situación de empleo y hemos preguntado si la presencia de las mujeres dentro de una organización o la de padres de familia trabajadores incita a las organizaciones a instaurar medidas de conciliación y de ORTT. Es interesante constatar que las personas sin hijos ocupan más frecuentemente empleos que ofrecen mayores servicios para personas de edad avanzada y para la guardería de niños. En lo que a la ORTT se refiere, mostramos que los comportamientos de las mujeres sin hijos se asemejan a los de los hombres, pero que la presencia de hijos es un factor fundamental para explicar las aspiraciones de los hombres en cuanto al tiempo de trabajo.

    Full Text Available Approximately one in three older people fall each year owing to gait/balance disorder/weakness, the second leading cause of falls in older adults. This review evaluates the capability of different balance measurement tools to predict falls in the elderly, which are used routinely for assessing balance impairment. Balance measurement tools reviewed are the Timed Up and Go test, Berg Balance Scale, Tinetti Performance Oriented Mobility Assessment, Functional Reach Test, Clinical Test of Sensory Integration for Balance, and the postural sway measurements or center of pressure. The effect of balance training on the postural control mechanism and its efficacy in fall prevention in older adults were also reviewed. The current evidence is not conclusive enough to favor existing balance measurement tools and balance training implemented for fall prevention in older adults.

    Two of the biggest challenges facing the US power industry today are retaining an experienced, capable workforce and operating and maintaining a reliable, diversified fleet of generating plants. Success in the marketplace requires a proper balancing of staff and new technology, something few gencos do well. Following this introductory paper in this issue are several technical articles representing a small sample of the steps that gencos nationwide are taking to prolong plant life. Unlike the false promise of Ponce de Leon's fountain of youth in Florida, the promise of longer life for aging plants is real wherever experienced engineers and technicians are on the job. The article looks at problems across America, from the East Coast to the West Coast. It is supported by diagrams projecting US new capacity and plant type additions up to 2014. 5 figs.

    Given a system M in a thermal bath we obtain a generalized detailed balance relation for the ratio r=π _τ (K→ J)/π _τ (J→ K) of the transition probabilities M:J→ K and M:K→ J in time τ . We assume an active bath, containing solute molecules in metastable states. These molecules may react with M and the transition J→ K occurs through different channels α involving different reactions with the bath. We find that r=sum p^α r^α , where p^α is the probability that channel α occurs, and r^α depends on the amount of heat (more precisely enthalpy) released to the bath in channel α.

  16. Balanced Branching in Transcription Termination

    Harrington, K J; Liang, S

    2000-01-01

    The theory of stochastic transcription termination based on free-energy competition requires two or more reaction rates to be delicately balanced over a wide range of physical conditions. A large body of work on glasses and large molecules suggests that this should be impossible in such a large system in the absence of a new organizing principle of matter. We review the experimental literature of termination and find no evidence for such a principle but many troubling inconsistencies, most notably anomalous memory effects. These suggest that termination has a deterministic component and may conceivably be not stochastic at all. We find that a key experiment by Wilson and von Hippel allegedly refuting deterministic termination was an incorrectly analyzed regulatory effect of Mg2+ binding.

    Full Text Available Background: Balance emerges from the interaction of multiple systems that are organized to meet functional task goals and that are constrained by environmental context, but is often compromised with advancing age. At least 30% of older people experience decline in physical activity after entry into residential care. Participation in activity is more difficult for older people because of fear, lack of motivation, depression and poor understanding of the long term benefits of physical activity. Thus our purpose was to investigate effect of specific balance strategy training programme as compared to general balance training in improving balance in institutionalized elderly population. Methods: 26 institutionalized elderly subjects participated in the study. Participants in group A were given specific balance strategy training programme and those in group B were given general balance training. Intervention was for 40 min per day, thrice a week for 4 weeks. Balance was assessed using Berg balance scale and Timed up and go test. Result: Both the interventions showed marked improvement in balance when assessed on Berg balance and Timed up and go test. The group having specific balance strategy training programme proved to be significantly better than general balance training programme. Conclusion: Specific balance strategy training programme being more effective than general regimens should be incorporated in addressing balance related problems of institutionalized elderly population.

La calibración obtenida es referida a los coeficientes de cultivo (Kc, fracción de agotamiento del suelo (p y propiedades hidráulicas del suelo en suelos Ferralíticos Rojos compactados. El procedimiento empleado consistió en ajustar primeramente las propiedades del suelo siguiendo un procedimiento interactivo para determinar valores de Kc y p que minimizaran las diferencias en el contenido de agua en el suelo, entre los valores observados y simulados durante el ciclo del cultivo. Los siguientes indicadores de ajuste y eficiencia de la validación fueron empleados para asegurar la calibración y validación del modelo: coeficiente de regresión forzado del original (b, coeficiente de determinación (R², error cuadrático medio (RMSE y error absoluto medio (AAE. Los resultados muestran un buen ajuste entre los valores observados en observaciones de campo y las predicciones del modelo, con valores de b cercanos a 1,0; R² en el rango de 0,84-0,95 para la calibración y 0,78-0,90 para la validación en todos los cultivos. El RMSE y AAE son pequeños, con valores de RMSE en el rango entre 0,97-2,08 mm para la calibración y 1,07-2,82 mm para la validación. Los valores de Kc y p en el rango sugeridos en el FAO 56. Dichos resultados permiten utilizar el modelo ISAREG como alternativa viable en la programación de riego y con esto incrementar la productividad del agua en Cuba.

    2012-12-01

    Full Text Available Guava response to liming and fertilization can be monitored by tissue testing. Tissue nutrient signature is often diagnosed against nutrient concentration standards. However, this approach has been criticized for not considering nutrient interactions and to generate numerical biases as a result of data redundancy, scale dependency and non-normal distribution. Techniques of compositional data analysis can control those biases by balancing groups of nutrients, such as those involved in liming and fertilization. The sequentially arranged and orthonormal isometric log ratios (ilr or balances avoid numerical bias inherent to compositional data. The objectives were to relate tissue nutrient balances with the production of "Paluma" guava orchards differentially limed and fertilized, and to adjust the current patterns of nutrient balance with the range of more productive guava trees. It was conducted one experiment of 7-yr of liming and three experiments of 3-yr with N, P and K trials in 'Paluma' orchards on an Oxisol. Plant N, P, K, Ca and Mg were monitored yearly. It was selected the [N, P, K | Ca, Mg], [N, P | K], [N | P] and [Ca | Mg] balances to set apart the effects of liming (Ca-Mg and fertilizers (N-K on macronutrient balances. Liming largely influenced nutrient balances of guava in the Oxisol while fertilization was less influential. The large range of guava yields and nutrient balances allowed defining balance ranges and comparing them with the critical ranges of nutrient concentration values currently used in Brazil and combined into ilr coordinates.

    Traditional management of electricity portfolios is focused on the day-ahead market and futures of longer maturity. Within limits, market participants can however also resort to the balancing energy market to close their positions. In this paper, we determine strategic positions in the balancing energy market and identify corresponding economic incentives in an analysis of the German balancing energy demand. We find that those strategies allow an economically optimal starting point for real-time balancing and create a marketplace for flexible capacity that is more open than alternative marketplaces. The strategies we proffer in this paper we believe will contribute to an effective functioning of the electricity market. (author)

  13. Competing values in healthcare: balancing the (un)balanced scorecard.

    Science.gov (United States)

    Wicks, Angela M; St Clair, Lynda

    2007-01-01

    Facing a complex environment driven by two decades of dramatic change, healthcare organizations are adopting new strategic frameworks such as the Balanced Scorecard (BSC) to evaluate performance (Kaplan and Norton 1992). The BSC was not originally developed as a performance management tool, however. Rather, it was designed as a tool to communicate strategy and, as such, provides little guidance when actual outcomes fall short of desired outcomes. In addition, although the BSC is an improvement over exclusively financial measures, it has three conceptual limitations that are especially problematic for evaluating healthcare organizations: (1) it underemphasizes the employee perspective, (2) it is founded on a control-based management philosophy, and (3) it emphasizes making trade-offs. To address these limitations, we propose using the Competing Values Framework (CVF), a theoretically grounded, comprehensive approach to understanding and improving organizational and managerial performance by focusing on four action imperatives: competing, controlling, collaborating, and creating. The CVF pays particular attention to the employee perspective, is consistent with a commitment-based management philosophy, and emphasizes transcending apparent paradoxes to identify win-win solutions. Rather than focusing on customer satisfaction or employee satisfaction, the CVF looks for ways to satisfy customers and employees while still addressing financial constraints and growth opportunities. The CVF also can be used to assess both the culture of the organization and the competencies of individual managers, thereby providing a clear link between strategy and implementation.

Seven groups of Wistar rats were used. One group was killed on the first experimental day being utilized as control of initial body copper content. Six groups of rats were fed, over 15 days, semipurified diets varying only in the fat level, three of them containing 8% of fat, and the other three 2%. The overall copper balance was studied by calculating differences between the initial and final body copper content. During the last week, another copper balance was carried out by monitoring intake and faecal copper excretion. Body mass, and liver, spleen, skin, erythrocytes and serum copper contents were also examined. The copper utilization was lower in 2% fat rats, this was caused by food intake decrease but also by the lower copper bioavailability in 2% fat diets. The corporal, liver and spleen copper contents were reduced, and liver, skin and serum copper concentrations also decreased in the rats fed on 2% fat diets. Palm olein (8% versus olive and sunflower oil produced a lower efficiency of copper absorption.

    Full Text Available Nell'attuale  periodo di  programmazione della PAC la  protezione  e  il  miglioramento  delle infrastrutture  gestite dalle aziende agricole e  che  contribuiscono grandemente alla determinazione della qualità del  paesaggio  rurale,  compreso  quelle  ad  alta  valenza  ecologica,  sono  state  rese  possibili  rispettivamente dall'applicazione  dello Standard di Condizionalità 4.4 : “Mantenimento degli elementi caratteristici del paesaggio” e dall’adesione alla Misura agroambientale 323: “Tutela e riqualificazione del patrimonio rurale”  implementata dai PSR.In questo studio, che ha riguardato la valutazione paesaggistica di un’area del Comune di Conegliano, si è inteso fornire uno strumento su base geografica  che, insieme ad altri strumenti di valutazione, consenta la redazione di carte tematiche di “monitoraggio  quantitativo” della valenza degli elementi caratteristici del paesaggio e dell’impatto dei livellamenti, consentendo anche di rappresentarne la percezione dinamica. Il monitoraggio quantitativo può consentire alle Amministrazioni locali di trarre elementi di  giudizio e di scelta idonei a tutelare gli aspetti paesistici dei distretti rurali ove l’attività vitivinicola gioca un ruolo fondamentale fra le attività economiche. Sulla base di tali elementi di  giudizio e di scelta sarà possibile predisporre i regolamenti di governo del territorio, efficaci nella tutela del paesaggio, da far rispettare per l’ottenimento della concessione dell’autorizzazione, cui lo standard di Condizionalità 1.1.b fa riferimento. Le metodologie proposta non sono alternative all’Approccio di Valutazione Storico Culturale (AVASC proposto da Agnoletti (2010 che valuta la dinamica dell’uso del suolo e i cambiamenti avvenuti in un ampio arco temporale al fine di definire come “caratteristico” un elemento del paesaggio.

    Reduced balance confidence is associated with impairments in features of balance and gait in individuals with subacute stroke. However, an understanding of these relationships in individuals at the chronic stage of stroke recovery is lacking. This study aimed to quantify the relationships between balance confidence and specific features of balance and gait in individuals with chronic stroke. Participants completed a balance confidence questionnaire and clinical balance assessment (quiet standing, walking, and reactive stepping) at 6 months postdischarge from inpatient stroke rehabilitation. Regression analyses were performed using balance confidence as a predictor variable, and quiet standing, walking, and reactive stepping outcome measures as the dependent variables. Walking velocity was positively correlated with balance confidence, whereas mediolateral center of pressure excursion (quiet standing) and double support time, step width variability, and step time variability (walking) were negatively correlated with balance confidence. This study provides insight into the relationships between balance confidence and balance and gait measures in individuals with chronic stroke, suggesting that individuals with low balance confidence exhibited impaired control of quiet standing as well as walking characteristics associated with cautious gait strategies. Future work should identify the direction of these relationships to inform community-based stroke rehabilitation programs for individuals with chronic stroke, and determine the potential utility of incorporating interventions to improve balance confidence into these programs.
