La finca de la Muntanya d’Alinyà és l’única zona del món on es poden observar les quatre espècies de voltors europeus: voltor comú (Gyps fulvus), voltor negre (Aegypius monachus), aufrany (Neophron percnopterus) i trencalòs (Gypaetus barbatus). Davant el problema de l’abandonament del poble i de l’envelliment de la població es planteja una alternativa de futur vers a una economia no tant basada en la ramaderia i l’agricultura, que són les activitats agropecuàries tradicionals a la zona. La recent intervenció de la Fundació Territori i Paisatge ha determinat, en gran part, el futur d’aquestes aus a Alinyà. Per una altra banda, les normatives vigents eren molt restrictives, fins fa ben poc, sobre l’aprofitament per part dels voltors de les restes d’animals morts provinents de la ramaderia. Ara neix una nova perspectiva de futur de tipus turístic.

Approximately 40,000 tons of deteriorated asphalt concrete has been removed from Interstate 80 in Cass County and stockpiled. Laboratory tests indicate that this material has considerable value when upgraded with new aggregate and asphalt cement. This report documents the procedures used and results obtained on an experimental recycling project. It was demonstrated that present drum mixing-recycling equipment and procedures can be used to utilize this material with satisfactory results. Laboratory analyses of material components and mixtures were performed; these analyses indicate mixture can be produced that is uniform, stable, and very closely resembles mixture produced with all virgin material. A 1700 foot long test section was constructed on US 169 in Kossuth County wherein salvaged asphalt concrete from I-80 in Cass County was utilized. The salvaged mix was blended with virgin aggregate and recycled through a modified drum mixing plant, the reprocessed mixture was satisfactorily placed 1 1/2 inches thick as a resurfacing course on an old PCC pavement. An inspection of the test section was made in December of 1978 to evaluate the performance after one full year of service. There was no evidence of rutting or shoving from traffic. The surface does, however, have a very dry and somewhat ravelled appearance. This can be related to a low asphalt content in the mix and some temperature control problems which were difficult to get fully corrected on such a short project and with a short supply of readily available materials.

Over the last few decades, advances have been made in the understanding of myofascial pain syndrome epidemiology, clinical characteristics and aetiopathogenesis, but many unknowns remain. An integrated hypothesis has provided a greater understanding of the physiopathology of trigger points, which may allow the development of new diagnostic, and above all, therapeutic methods, as well as the establishment of prevention policies and protocols by the health profession. Nevertheless, randomized studies are needed to provide a better understanding and detection of the different factors involved in the origin of trigger points.

BACKGROUND: Prognostic models have been developed to predict survival of patients with newly diagnosed glioblastoma (GBM). To improve predictions, models should be updated with information at the recurrence. We performed a pooled analysis of European Organization for Research and Treatment of Cancer (EORTC) trials on recurrent glioblastoma to validate existing clinical prognostic factors, identify new markers, and derive new predictions for overall survival (OS) and progression free survival (PFS).¦METHODS: Data from 300 patients with recurrent GBM recruited in eight phase I or II trials conducted by the EORTC Brain Tumour Group were used to evaluate patient's age, sex, World Health Organisation (WHO) performance status (PS), presence of neurological deficits, disease history, use of steroids or anti-epileptics and disease characteristics to predict PFS and OS. Prognostic calculators were developed in patients initially treated by chemoradiation with temozolomide.¦RESULTS: Poor PS and more than one target lesion had a significant negative prognostic impact for both PFS and OS. Patients with large tumours measured by the maximum diameter of the largest lesion (⩾42mm) and treated with steroids at baseline had shorter OS. Tumours with predominant frontal location had better survival. Age and sex did not show independent prognostic values for PFS or OS.¦CONCLUSIONS: This analysis confirms performance status but not age as a major prognostic factor for PFS and OS in recurrent GBM. Patients with multiple and large lesions have an increased risk of death. With these data prognostic calculators with confidence intervals for both medians and fixed time probabilities of survival were derived.

The major objective of this project is to evaluate image analysis for characterizing air voids in Portland cement contract (PCC) and asphalt concrete (AC) and aggregate gradation in asphalt concrete. Phase 1 of this project has concentrated on evaluation and refinement of sample preparation techniques, evaluation of methods and instruments for conducting image analysis, and finally, analysis and comparison of a select portion of samples. Preliminary results suggest a strong correlation between the results obtained from the linear traverse method and image analysis methods for determining percent air voids in concrete. Preliminary work with asphalt samples has shown that damage caused by a high vacuum of the conventional scanning electron microscope (SEM) may too disruptive. Alternative solutions have been explored, including confocal microscopy and low vacuum electron microscopy. Additionally, a conventional high vacuum SEM operating at a marginal operating vacuum may suffice.

BACKGROUND AND PURPOSE: Needs of patients dying from stroke are poorly investigated. We aim to assess symptoms of these patients referred to a palliative care consult team, and to review their treatment strategies. METHODS: All charts of patients dying from stroke in a tertiary hospital, and referred consecutively to a palliative care consultant team from 2000 to 2005, were reviewed retrospectively. Symptoms, ability to communicate, treatments, circumstances and causes of death were collected. RESULTS: Forty-two patients were identified. Median NIH Stroke Scale on admission was 21. The most prevalent symptoms were dyspnoea (81%), and pain (69%). Difficulties or inability to communicate because of aphasia or altered level of consciousness were present in 93% of patients. Pharmacological respiratory treatments consisted of anti-muscarinic drugs (52%), and opioids (33%). Pain was mainly treated by opioids (69%). During the last 48 h of life, 81% of patients were free of pain and 48% of respiratory distress. The main causes of death were neurological complications in 38% of patients, multiple medical complications in 36%, and specific medical causes in 26%. CONCLUSIONS: Patients dying from stroke and referred to a palliative care consult team have multiple symptoms, mainly dyspnoea and pain. Studies are warranted to develop specific symptoms assessment tools in non-verbal stroke patients, to accurately assess patients' needs, and to measure effectiveness of palliative treatments.

Tutkimuksen tarkoituksena on selvittää kuinka moninaisuus ja sen johtaminen näkyvät voittoa tavoittelemattoman järjestön tiimityössä, kuinka moninaisuus ja tiimityö pystyvät selittämään motiiveja työskennellä voittoa tavoittelemattomassa järjestössä ja mitä tulisi huomioida tiimityön ja tiimin johtajuuden osalta, kun moninaisuus ja voittoa tavoittelemattoman järjestön luonne otetaan huomioon. Tämä tutkielma on laadullinen tutkimus, jossa tutkimusmenetelminä on käytetty yhdeksää teemahaastattelua, edellisen tutkimuksen tuloksia (Astikainen, 2005) sekä havainnointia. Tutkimuksen perusteellavoidaan todeta, että voittoa tavoittelemattoman järjestön luonne, tiimityö tai moninaisuus eivät sinällään merkitse paljoakaan tulosten kannalta, vaan niiden keskinäiset yhteydet. Nämä yhdessä, oikein hyödynnettynä, vaikuttavat työntekijöiden motivaatioon ja sitä kautta organisaation tuloksiin.

L’estancament que han patit històricament les comarques dels Pallars (Jussà i Sobirà) tant a nivell humà com econòmic, ha ajudat, fins fa pocs anys, a conservar fossilitzades estructures socials, religioses i humanes de diferents períodes, alhora que a nivell científic, aquest estancament té com a conseqüència la marginació quant al gruix de les investigacions que es fan a la resta del país. Es proposa en aquest treball de síntesi una anàlisi i contrastació de les dades que ens ofereix la historiografia quant al poblament i la seva evolució des de la Prehistòria fins al període tardoromà al Paratge de Montcortès i Pla de Corts (Baix Pallars, Pallars Sobirà), amb l’aportació de les darreres investigacions, encara sense publicar, que ens proporcionen, alhora que noves dades quantitatives, informació qualitativa sobre el funcionament d’aquests grups humans, és a dir, una nova perspectiva biofísica sobre la coevolució dels nous sistemes socioeconòmics amb els ecosistemes naturals en aquest territori.

L'objectiu d'aquest estat de la qüestió és analitzar com s'ha tractat historiogràficament l'entrada d'un corrent intel·lectual i cultural nou com és l'humanisme. A partir de la bibliografia suggerida pels principals manuals especialitzats d'Història d'Espanya es veu com l'objecte d'estudi aquí contemplat genera dues escoles interpretatives: per una banda, aquells autors hispanistes i d'influència hispanista que defensen un humanisme vinculat amb Erasme de Rotterdam i centrat en la religió i l'espiritualitat. Així mateix, els autors que segueixen aquesta interpretació destaquen la feina del Cardenal Cisneros com a promotor de profundes transformacions en el clergat espanyol i com a promotor de la fundació de la Universitat d'Alcalà, lloc on es va desenvolupar aquest tipus d'humanisme. Per altra banda, la segona escola interpretativa la formen autors espanyols que prenen com a referència a Luis Gil Fernández. Aquests contemplen la recuperació dels autors grecollatins, dels temes i les formes clàssiques com la fita fonamental de l'humanisme. Segons aquesta escola, els estudis de gramàtica i la pedagogia són també objectius dels autors humanistes.

Se presentan diversas cuestiones de la relación entre los modelos helénicos de las colonias de Emporion y Rhode y las costumbres indígenas evidenciadas en los yacimientos ibéricos de su entorno. Los cultos de Artemis y Apolo como dioses protectores de la emporía arcaica de los foceos, el urbanismo de Rhode en el siglo III a.C., los cultos emporitanos, la interpretación del yacimiento de Pontós, la mezcla de cultos griegos y celtas en Ullastret y Pontós y un cálato excepcional en un campo de silos al pie de S. Julià, se estudian como evidencias de esta relación. En el siglo II a.C., Roma implantará un nuevo orden político y económico del que Emporion será la gran beneficiada.

BACKGROUND: Frequent emergency department users represent a small number of patients but account for a large number of emergency department visits. They should be a focus because they are often vulnerable patients with many risk factors affecting their quality of life (QoL). Case management interventions have resulted in a significant decrease in emergency department visits, but association with QoL has not been assessed. One aim of our study was to examine to what extent an interdisciplinary case management intervention, compared to standard emergency care, improved frequent emergency department users' QoL. METHODS: Data are part of a randomized, controlled trial designed to improve frequent emergency department users' QoL and use of health-care resources at the Lausanne University Hospital, Switzerland. In total, 250 frequent emergency department users (≥5 attendances during the previous 12 months; ≥ 18 years of age) were interviewed between May 2012 and July 2013. Following an assessment focused on social characteristics; social, mental, and somatic determinants of health; risk behaviors; health care use; and QoL, participants were randomly assigned to the control or the intervention group (n=125 in each group). The final sample included 194 participants (20 deaths, 36 dropouts, n=96 in the intervention group, n=99 in the control group). Participants in the intervention group received a case management intervention by an interdisciplinary, mobile team in addition to standard emergency care. The case management intervention involved four nurses and a physician who provided counseling and assistance concerning social determinants of health, substance-use disorders, and access to the health-care system. The participants' QoL was evaluated by a study nurse using the WHOQOL-BREF five times during the study (at baseline, and at 2, 5.5, 9, and 12 months). Four of the six WHOQOL dimensions of QoL were retained here: physical health, psychological health, social relationship, and environment, with scores ranging from 0 (low QoL) to 100 (high QoL). A linear, mixed-effects model with participants as a random effect was run to analyze the change in QoL over time. The effects of time, participants' group, and the interaction between time and group were tested. These effects were controlled for sociodemographic characteristics and health-related variables (i.e., age, gender, education, citizenship, marital status, type of financial resources, proficiency in French, somatic and mental health problems, and behaviors at risk).

UNLABELLED: NYVAC, a highly attenuated, replication-restricted poxvirus, is a safe and immunogenic vaccine vector. Deletion of immune evasion genes from the poxvirus genome is an attractive strategy for improving the immunogenic properties of poxviruses. Using systems biology approaches, we describe herein the enhanced immunological profile of NYVAC vectors expressing the HIV-1 clade C env, gag, pol, and nef genes (NYVAC-C) with single or double deletions of genes encoding type I (ΔB19R) or type II (ΔB8R) interferon (IFN)-binding proteins. Transcriptomic analyses of human monocytes infected with NYVAC-C, NYVAC-C with the B19R deletion (NYVAC-C-ΔB19R), or NYVAC-C with B8R and B19R deletions (NYVAC-C-ΔB8RB19R) revealed a concerted upregulation of innate immune pathways (IFN-stimulated genes [ISGs]) of increasing magnitude with NYVAC-C-ΔB19R and NYVAC-C-ΔB8RB19R than with NYVAC-C. Deletion of B8R and B19R resulted in an enhanced activation of IRF3, IRF7, and STAT1 and the robust production of type I IFNs and of ISGs, whose expression was inhibited by anti-type I IFN antibodies. Interestingly, NYVAC-C-ΔB8RB19R induced the production of much higher levels of proinflammatory cytokines (tumor necrosis factor [TNF], interleukin-6 [IL-6], and IL-8) than NYVAC-C or NYVAC-C-ΔB19R as well as a strong inflammasome response (caspase-1 and IL-1β) in infected monocytes. Top network analyses showed that this broad response mediated by the deletion of B8R and B19R was organized around two upregulated gene expression nodes (TNF and IRF7). Consistent with these findings, monocytes infected with NYVAC-C-ΔB8RB19R induced a stronger type I IFN-dependent and IL-1-dependent allogeneic CD4(+) T cell response than monocytes infected with NYVAC-C or NYVAC-C-ΔB19R. Dual deletion of type I and type II IFN immune evasion genes in NYVAC markedly enhanced its immunogenic properties via its induction of the increased expression of type I IFNs and IL-1β and make it an attractive candidate HIV vaccine vector. IMPORTANCE: NYVAC is a replication-deficient poxvirus developed as a vaccine vector against HIV. NYVAC expresses several genes known to impair the host immune defenses by interfering with innate immune receptors, cytokines, or interferons. Given the crucial role played by interferons against viruses, we postulated that targeting the type I and type II decoy receptors used by poxvirus to subvert the host innate immune response would be an attractive approach to improve the immunogenicity of NYVAC vectors. Using systems biology approaches, we report that deletion of type I and type II IFN immune evasion genes in NYVAC poxvirus resulted in the robust expression of type I IFNs and interferon-stimulated genes (ISGs), a strong activation of the inflammasome, and upregulated expression of IL-1β and proinflammatory cytokines. Dual deletion of type I and type II IFN immune evasion genes in NYVAC poxvirus improves its immunogenic profile and makes it an attractive candidate HIV vaccine vector.

La comunicació com a mètode per aprendre no és nou, tot i així les noves tecnologies obren la porta a noves oportunitats i nous projectes entorn aquest concepte. No només es tracta de treballar elements curriculars, sinó també actitudinals a través de la opció de connexió entre contextos. L’objectiu d’aquesta recerca és analitzar quina és l’actitud i els aprenentatges i/o retencions dels infants a partir d’una connexió generada entre dos contextos. Per tal de donar resposta a aquest plantejament de la investigació es crea una intervenció entre les aules i s’utilitzen com a instruments de recollida de dades les observacions, els dibuixos i els grups de discussió. Els resultats mostren una actitud oberta i d’interès per part dels infants davant de la metodologia de comunicació a l’aula, però un aprenentatge i/o retenció relacionat amb els continguts dels elements de l’altre context per sobre dels elements TIC. Es conclou doncs que dins l’aula treballant amb les noves tecnologies es genera un incentiu pels infants fent evident que hi ha hagut un aprenentatge compartit.

El present projecte exposa un estudi sobre la motivació, un dels factors psicològics que intervenen en l’àmbit esportiu, concretament en el futbol. Es fa èmfasi en els tipus de motivació, les teories, els factors que hi intervenen, les tècniques que s’utilitzen i també el paper que desenvolupa l’entrenador en aquest àmbit. La investigació es situa en tres equips de futbol de categoria juvenil masculí, en la qual es pretén conèixer i analitzar com influeix en els jugadors la motivació i la seva participació en aquest esport. Es conclou sobre la necessitat de seguir treballant la motivació en cada equip per tal d’afavorir una major implicació dels jugadors i un clima més òptim de treball i sobre la importància de noves actuacions i tècniques que tinguin en compte la motivació a dos nivells: individual i col·lectiu.

Aquest projecte té com a finalitat desenvolupar un sistema no destructiu per a la caracterització de les plantacions de vinya i d’arbres fruiters mitjançant la utilització d’un sensor làser (LiDAR - Light Detection and Ranging). La informació obtinguda ha de permetre estudiar la resposta del cultiu a determinades accions (poda, reg, adobs, etc.); i també realitzar tractaments fitosanitaris adaptats a la densitat foliar del cultiu. La posada a punt del sistema (software i hardware) es va realitzar a escala reduïda mitjançant proves de laboratori sobre un arbre ornamental. Obtenint la configuració del sensor LiDAR més adequada i la calibració de tot el sistema. L’any 2004 van realitzar assajos en plantacions de pomera, perera, cítrics i vinya. L’objectiu era posar a prova el sistema i obtenir dades dels cultius. Amb la introducció de canvis i millores en el sistema i en la metodologia de treball, l’any 2005 es van realitzar nous assajos, però només en perera Blanquilla i en vinya Merlot. En tots els assajos s’escanejaven unes franges de vegetació concretes i posteriorment es desfullaven manualment per a calcular-ne l’Índex d’Àrea Foliar (IAF). Les dades obtingudes amb el sensor LiDAR s’han analitzat mitjançant l’aplicació de la metodologia desenvolupada per Walklate et al.(2002) i s’han obtingut determinats paràmetres vegetatius de cultiu, que posteriorment s’han correlacionat amb l’Índex d’Àrea Foliar (IAF) obtingut de forma experimental. La capacitat de predicció de l’Índex d’Àrea Foliar (IAF) per part dels diferents paràmetres calculats es diferent en cada cultiu, essent necessàries més proves i major nombre de dades a fi d’obtenir un model fiable per a l’estimació de l’IAF a partir de les lectures del sensor LiDAR. L’estudi de la variabilitat de la vegetació mitjançant l’anàlisi de la variabilitat del Tree Area Index (TAI) al llarg de la fila ha permès determinar el nombre mínim necessari d’escanejades acumulades per a l’estimació fiable de l’Índex d’Àrea Foliar. Finalment s’ha estudiat la incidència de l’alçada de col•locació del sensor LiDAR respecte la vegetació.
