Variaciones interanuales de la precipitación de verano y el rendimiento del cultivo de la vid en Mendoza

Eduardo Andrés Agosta

2010-12-01

Full Text Available La producción de vid es la fuente económica agroindustrial principal en Cuyo (28°S-36°S / 65°W-70°W, siendo la región de más elevado desarrollo vitivinícola del país. Uno de los factores climáticos de mayor impacto en la producción de vid es la destrucción del cultivo por granizo, como resultado de la convección severa desarrollada en época estival. La violencia con que se desarrollan las tormentas estivales de granizo genera un impacto importante en el rendimiento de los viñedos afectados, logrando la disminución parcial o total de parcelas enteras. Durante el período 1979-2008, la precipitación de verano presenta fluctuaciones de la escala 7-8 años al igual que la producción total de vid y ambas se encuentran inversamente correlacionadas intradecádicamente. Asimismo, veranos húmedos (secos pueden presentar mayor (menor probabilidad de ocurrencia de daños por granizo en la temporada actual que se pueden asociar a menor (mayor producción de vid en la temporada del año siguiente debido a cambios en la disponibilidad de yemas fértiles. También una fracción de la variación de la producción de vid en el verano actual puede estar asociada a cambios en la precipitación de ese verano por daño directo (intensidad de la precipitación o indirecto (anegamiento relativamente prolongado ya que la desfoliación y asfixia radicular parecen afectar el rendimiento de las plantas. La clara dependencia climática de cultivo muestra que la producción total anual de vid está modulada por las variaciones de la precipitación en escalas decádicas, la cual está vinculada a factores de escala global del sistema climático. Se derivan potenciales resultados para el pronóstico de la producción de vid bajo futuros escenarios de cambio climático para la región.The grape production is the main economic source in the agro-industry of Cuyo (28°S-36°S / 65°W- 70°W, becoming the most developed region for wine production in Argentina

Regulation of Hxt3 and Hxt7 turnover converges on the Vid30 complex and requires inactivation of the Ras/cAMP/PKA pathway in Saccharomyces cerevisiae.

Directory of Open Access Journals (Sweden)

Chris Snowdon

Full Text Available Eukaryotic cells adjust their intracellular protein complement as a mechanism to adapt to changing environmental signals. In Saccharomyces cerevisiae the hexose transporters Hxt3 and Hxt7 are expressed and function on the plasma membrane in high and low glucose abundance, respectively. By contrast, Hxt3 is endocytosed and degraded in the vacuole when cells are starved of glucose and Hxt7 in response to rapamycin treatment or when nitrogen is limiting. Yeast uses several signaling pathways, including the TORC1 and Ras/cAMP/Protein Kinase A (PKA pathways, to adapt to nutrient changes in the environment. The multi-protein Vid30 complex (Vid30c, an E3 ubiquitin ligase required for the degradation of FBPase, assists in this adaptation process in a mechanism that is poorly understood. Here we show the endocytosis and the subsequent degradation of both Hxt3 and Hxt7, in response to different nutrient signals, is dependent on components of the Vid30c. Additionally, we define the signaling events required for the turnover of Hxt3 and Hxt7 by showing that Hxt3 turnover requires Ras2 and PKA inactivation, whereas Hxt7 turnover requires TORC1 and Ras2 inactivation. Further investigation led us to identify Rim15, a kinase that is inhibited by both the TORC1 and Ras/cAMP/PKA pathways, as a key downstream effector in signaling both turnover events. Finally, we show that the turnover of both Hxt3 and Hxt7 is dependent on the essential E3 ubiquitin ligase, Rsp5, indicating that the role of the Vid30c might be indirect of Hxt ubiquitylation.

Les utilités du jeu vidéo sérieux : finalités, discours et mises en corrélation

Directory of Open Access Journals (Sweden)

Etienne Armand Amato

2011-05-01

Full Text Available Les jeux vidéo sérieux offrent aujourd’hui une grande diversité de catégories et d’usages. Ils prétendent changer notre rapport au monde comme au jeu. Pour surmonter les paradoxes provenant de l’opposition entre activité ludique et activité sérieuse, il est préférable d’étudier ces nouveaux produits en termes d’utilité. La méthode de la recherche présentée ici a consisté à prendre en considération le point de vue et les intérêts particuliers de ceux qui les produisent – les émetteurs –, et de ceux qui les pratiquent – les récepteurs. Le résultat obtenu est que leurs finalités respectives sont surtout convergentes et complémentaires dans le cas de la formation et du soin, alors qu’elles divergent et changent de nature dans le domaine de la communication journalistique, politique et surtout publicitaire. Il se trouve que cette réalité est masquée par le discours des promoteurs des jeux sérieux qui tiennent des propos très globalisants. Pour dépasser la rhétorique des acteurs d’un secteur en pleine expansion, une nouvelle définition du jeu vidéo sérieux est finalement proposée. Elle se fonde sur l’instrumentalisation du jeu vidéo et conclut sur l’idée que tous les jeux sérieux cherchent à mettre en corrélation effective le jeu et la réalité.

Full Text Available L’aparició d’un objecte excepcional fet d’os de bòvid anomenat tap en emplaçaments rituals de la segona edat del ferro va permetre fa uns anys postular una hipòtesi anomenada d’”economia funerària”. Les dades procedents d’assentaments suggereixen que la cabana ramadera va canviar en la seva composició, disminuint la quantitat de bòvids en favor dels ovicàprids. El perfil de sacrifici també va canviar orientant l’ús d’aquests animals domèstics cap a l’obtenció de productes secundaris i la força de treball. Les recents troballes de la necròpolis de Son Real i del Santuari de la Punta des Patró a Mallorca apunten vers un ritual de comensalitat, on presumiblement els sectors més rics de la societat haurien consumit carn de bòvid en els rituals funeraris o l’haurien emprada com a ofrena, en contraposició als grups menys rics que només haurien tingut accés a la carn de suid o ovicàprid.

Alternatively, one imaginative scene is to use video processing and pattern recognition technologies to automatically detect the cataract grade and intelligently control the release of the ultrasonic energy while operating. Unlike cataract grading in the diagnosis system with static images, complicated background, unexpected noise, and varied information are always introduced in dynamic videos of the surgery. Here we develop a VidEo-Based Intelligent Recognitionand Decision (VEBIRD system, which breaks new ground by providing a generic framework for automatically tracking the operation process and classifying the cataract grade in microscope videos of the phacoemulsification cataract surgery. VEBIRD comprises a robust eye (iris detector with randomized Hough transform to precisely locate the eye in the noise background, an effective probe tracker with Tracking-Learning-Detection to thereafter track the operation probe in the dynamic process, and an intelligent decider with discriminative learning to finally recognize the cataract grade in the complicated video. Experiments with a variety of real microscope videos of phacoemulsification verify VEBIRD’s effectiveness.

Le sens de l’écart : la narration déconstruite dans les vidéos de Willie Doherty

Directory of Open Access Journals (Sweden)

Valérie Morisson

2011-08-01

Full Text Available Dans les œuvres vidéographiques de l’artiste nord-irlandais Willie Doherty, les éléments narratifs entretiennent une relation complexe avec les images filmiques. Témoin de la guerre civile, récepteur méfiant des images du conflit, Doherty n’a de cesse de rappeler que la mémoire individuelle du traumatisme est erratique et le statut de victime problématique. La déconstruction du récit, l’instabilité de la focalisation, ainsi que l’écart, voire l’incompatibilité, entre l’image et le texte qui l’accompagne aboutissent à une réflexion sur les dissensions historiques. La voix off devient alors un facteur d’incertitude.In his video works, all tightly focused on the Northern-Irish conflict, Willie Doherty probes the perpetrator-victim dyad and denounces the truncated visual representation of the conflict by deconstructing the relation between image and sound. The texts uttered by the voice-over raise political issues relevant to post-conflict Ireland, whether it be victimhood, national trauma or the construction of collective memory. Multiple open-ended interwoven narratives accompany images without closing their interpretation.

Webbaserad pedagogisk meritportfölj - från idé till verklighet

Jakob Johansson

2011-03-01

Full Text Available Pedagogisk meritering och pedagogiska meritportföljer har under det senaste decenniet fått ökad uppmärksamhet. Idag (mars 2011 ger en sökning på Google® 6 140 respektive 1 990 träffar på dessa två sökord. Många av träffarna på Google® handlar om högskolors rekommendationer att dokumentera pedagogiska meriter, men antalet publicerade artiklar i detta ämne är mycket få. Högskolan behöver bra lärare och för att uppnå det så måste undervisning och andra utbildningsinsatser uppmärksammas och belönas. Användandet av pedagogiska meritportföljer anses öka betydelsen av undervisningsinsatsen vid anställningar och befordran och är ett sätt att professionalisera undervisning (Fayne, 1991. Många högskolor och universitet har utarbetat handlingsplaner för hur pedagogiska meriter ska dokumenteras och bedömas liksom strategier för hur medarbetarna ska utveckla sin pedagogiska skicklighet. ”Uppifrån” finns således både skrivna dokument och viljan och intentionen att premiera pedagogiska insatser. Trots detta upplever många medarbetare att pedagogiska insatser inte lönar sig att dokumentera då dessa meriter inte värderas tillräckligt högt, exempelvis i jämförelse med forskningsmeriter. Samtidigt vittnar pedagogiskt sakkunniga om att de pedagogiska meritportföljer som de ombeds granska (vid exempelvis tjänstetillsättningar ofta är ostrukturerade och av varierande kvalité. För att pedagogiska meriter ska få avsedd tyngd vid tjänstetillsättningar fordras att de redovisas på ett sätt som gör det möjligt för sakkunniga att värdera dem. Bedömning av både vetenskapliga och pedagogiska meriter görs i många fall av sakkunniga utan särskild pedagogisk utbildning och de pedagogiska meriterna anses generellt mer svårbedömda än de vetenskapliga (Lindberg, 1997. Någon form av standardisering och mallar i samband med presentation av pedagogiska meriter bör därför kunna vara till hjälp för s

Evaluation of the combined use of some radiolabeled chemotherapeutic agents and immunomodulator in imaging and treatment of experimentally induced tumor in mice

International Nuclear Information System (INIS)

Ali, E.T.E

2008-01-01

This study was performed to investigate how to label ancitabine and vidarabine with the Auger emitter 125 I and the effect of labeled drugs on tumor bearing mice. It was also conducted to investigate the possible effects of levamisole and dexamethasone as immunomodulators on the biodistribution and therapeutic effect of the labeled drugs. Furthermore, the hematological effect of immunomodulators and labeled drugs were also studied.Ancitabine(ANC) was labeled by electrophilic substitution with % labeling yield about 97,5. To obtain this yield, 10μg iodogen, for 5 minutes at temperature about 75 degree C were required at Ph 7 using phosphate buffer. Vidarabine (Vid) was labeled by the same techniques at Ph 7, with % labeling yield about 90 %. To obtain this yield, 200 μg iodogen, for 10 minutes at temperature about 75 degree C were required. Both 125 I-ANC and 125 I-Vid were stable for 48 hr post labeling without significant change in % labeling yield. The labeled drugs were investigated by electrophoresis analysis and thin layer chromatography using chloroform: ethanol: ammonia (90:10:0.5), respectively. Labeled drugs show opposite behavior on the two chromatograms. 125 I-ANC and 125 I-Vid were distributed rapidly in normal mice to different tissues, especially those of high proliferation rate such as stomach and excreted rapidly in urine.Biodistribution of 125 I-ANC and 125 I-Vid in tumor bearing mice showed increase in the uptake of radioactivity in tumor site with time. Also, the rate of decline of activity was rapid in most organs compared to tumor sites. The increase of uptake in thyroid, with time, reflect the in-vivo deiodination of the 125 I-ANC and 125 I-Vid by liver. The uptake of 125 I-ANC and 125 I-Vid may be sufficient to be used in imaging of tumor. Both DEX and LMS produced significant increase in the uptake of 125 I-ANC or 125 I-Vid in tumor sites and significant decrease in some other tissues. 125 I-ANC or 125 I-Vid produced toxic effect to

Full Text Available Skovoroda’s text Ubuždešsja, viděša slavu ego (hereafter uv was published for the first time in 1894 in the collection of Skovoroda’s works edited by Dmytro Bahalij, who defined them as an introduction to the Catechism classes held by the writer at Kharkiv College. uv bears no date, but its graphic, morphological and phonetic features can place it between the late 1750s-early-1760s. After a comprehensive linguistic revision, uv was included in Skovoroda’s last work Dialog, imja emu Potop zmiin (1791 as its concluding section (O Preobraženii. Although uv’s rhetorical function remains open to discussion, in my article I try to demonstrate that the liturgical function of its biblical quotations suggests that it might have been conceived as a catechetical instruction (malaja instrukcija on the liturgical feast of the Transfiguration. Furthermore, I also attempt a comparative analysis between the biblical quotations incorporated within uv and those preeminent in the Byzantine and Ruthenian sermons dedicated to the feast of the Transfiguration. What emerges from my analysis is the presence of common “quotational patterns” pointing to a shared Byzantino-Slavic tradition in the field of “sacred rhetoric”.

Conclusions: We found alterations in the visual and vestibular cortical network in VID patients that could underlie the typical VID symptoms such as a worsening of their vestibular symptoms when being exposed to challenging visual stimuli. These preliminary findings provide the first insights into the underlying functional brain connectivity in VID patients. Future studies should extend these findings by employing larger sample sizes, by investigating specific task-based paradigms in these patients and by exploring the implications for treatment.

Se plantean varios problemas: el de la integración de la videoconferência en la estructura orgánica y física de la institución, el de la integración pedagógica y dentro de éste como producir y fomentar la interacción entre los elementos personales y los contenidos de aprendizaje. Se repasan diferentes definiciones de la videoconferência y se hace énfasis en que esta tecnología es un canal de comunicación y un soporte de información, por lo tanto es un instrumento de interacción. Se analiza la interacción grupai y se demuestra por diferentes estudios que a través de la videoconferencia se pueden construir y mantener relaciones humanas. Observamos diferentes dimensiones y tipos de interacción didáctica para concluir que en la educación a distancia mediante diferentes estrategias a través de la videoconferência y en su proceso de utilización, se desarrolla una interacción con el contenido de aprendizaje, una interacción social entre los elementos personales del sistema y una interacción emocional, como lo demuestran las investigaciones realizadas en la UNED.ABSTRACT: The last technological advances implementation in distance education, specially vidéoconférence, suppose a necessity and a challenge.

2006-07-01

Full Text Available Abstract Background Identification of protein interaction networks has received considerable attention in the post-genomic era. The currently available biochemical approaches used to detect protein-protein interactions are all time and labour intensive. Consequently there is a growing need for the development of computational tools that are capable of effectively identifying such interactions. Results Here we explain the development and implementation of a novel Protein-Protein Interaction Prediction Engine termed PIPE. This tool is capable of predicting protein-protein interactions for any target pair of the yeast Saccharomyces cerevisiae proteins from their primary structure and without the need for any additional information or predictions about the proteins. PIPE showed a sensitivity of 61% for detecting any yeast protein interaction with 89% specificity and an overall accuracy of 75%. This rate of success is comparable to those associated with the most commonly used biochemical techniques. Using PIPE, we identified a novel interaction between YGL227W (vid30 and YMR135C (gid8 yeast proteins. This lead us to the identification of a novel yeast complex that here we term vid30 complex (vid30c. The observed interaction was confirmed by tandem affinity purification (TAP tag, verifying the ability of PIPE to predict novel protein-protein interactions. We then used PIPE analysis to investigate the internal architecture of vid30c. It appeared from PIPE analysis that vid30c may consist of a core and a secondary component. Generation of yeast gene deletion strains combined with TAP tagging analysis indicated that the deletion of a member of the core component interfered with the formation of vid30c, however, deletion of a member of the secondary component had little effect (if any on the formation of vid30c. Also, PIPE can be used to analyse yeast proteins for which TAP tagging fails, thereby allowing us to predict protein interactions that are not

Cut to the Chase: Editing Time and Space through Closed-Circuit Television Surveillance La fin des courses poursuites pour les policiers britanniques ? Le rôle de la vidéosurveillance dans le changement des représentations spatio-temporelles dans les courses poursuites

Full Text Available The UK is said to have the largest number of CCTV cameras of any European nation. These cameras have been involved in a variety of changes in UK police practices. Such changes range from new evidential practices in court cases, through access to new materials, to new questions posed regarding invasions of privacy. One unexplored area of police practices, which this paper will argue have undergone significant changes since the introduction of CCTV cameras, is police accountability. This paper will draw on recent controversies in the UK regarding police car chases to investigate the ways in which CCTV cameras have led to new and complex questions of police accountability.Le Royaume-Uni est souvent présenté comme le pays ayant le plus grand nombre de caméras en Europe. Ces caméras ont joué un rôle dans bien des changements intervenus au sein des pratiques de la police britannique, depuis la production de nouveaux types de preuves devant les tribunaux, en passant par l’accès à de nouveaux matériaux et à de nouvelles informations, jusqu’à la mise en lumière de nouvelles questions touchant aux violations de la vie privée. Un des aspects peu explorés parmi ces nouvelles pratiques policières concerne la question de la responsabilité et le fait, pour la police, de rendre des comptes. Cet article porte précisément sur les changements significatifs provoqués par l’introduction de caméras de vidéosurveillance dans la façon d’accomplir les activités policières. À partir du cas de controverses récentes au Royaume-Uni autour de courses poursuites dans lesquelles sont engagés des véhicules de police, il s’intéressera aux façons dont la présence et l’usage de caméras de vidéosurveillance ont amené des questions à la fois nouvelles et complexes, concernant la justification des actions de police.

Vitellointestinal duct (VID) or omphalomesenteric duct anomalies are secondary to the persistence of the embryonic vitelline duct, which normally obliterates by weeks 5-9 of intrauterine life. This is a retrospective analysis of a total of 16 patients of symptomatic remnants of vitellointestinal duct from period of Jan 2009 to May 2013. Male to female ratio (M:F) was 4.3:1 and mean age of presentation was 2 months and their mode of presentation was: patent VID in 9 (56.25%) patients, umbilical cyst in 2(12.25%), umbilical granuloma in 2 (12.25%), and Meckel diverticulum as content of hernia sac in obstructed umbilical hernia in 1 (6.25%) patient. Two patients with umbilical fistula had severe electrolyte disturbance and died without surgical intervention. Persistent VID may have varied presentations in infancy. High output umbilical fistula and excessive bowel prolapse demand urgent surgical intervention to avoid morbidity and mortality.

Vitamin D deficiency (VDD) in pregnant women and their children is an important health problem with severe consequences for the health of both. Thus, the objectives of this review were to reassess the magnitude and consequences of VDD during pregnancy, lactation and infancy, associated risk factors, prevention methods, and to explore epigenetic mechanisms in early fetal life capable of explaining many of the non-skeletal benefits of vitamin D (ViD). Original and review articles, and consensus documents with elevated level of evidence for VDD-related clinical decisions on the health of pregnant women and their children, as well as articles on the influence of ViD on epigenetic mechanisms of fetal programming of chronic diseases in adulthood were selected among articles published on PubMed over the last 20 years, using the search term VitD status, in combination with Pregnancy, Offspring health, Child outcomes, and Programming. The following items were analyzed: ViD physiology and metabolism, risk factors for VDD and implications in pregnancy, lactation and infancy, concentration cutoff to define VDD, the variability of methods for VDD detection, recommendations on ViD replacement in pregnant women, the newborn and the child, and the epigenetic influence of ViD. VDD is a common condition among high-risk pregnant women and their children. The routine monitoring of serum 25(OH)D3 levels in antenatal period is mandatory. Early preventive measures should be taken at the slightest suspicion of VDD in pregnant women, to reduce morbidity during pregnancy and lactation, as well as its subsequent impact on the fetus, the newborn and the child.

Diagnostic criteria for borderline personality disorder (BPD) include interpersonal problems and high reactivity to negative social interactions. However, experimental studies on these symptoms are scarce, and it remains unclear whether reactivity is also altered in response to positive social interactions. To simulate such situations, the present study used videographic stimuli (E.Vids; Blechert, Schwitalla, & Wilhelm, 2013) in which actors express rejecting, neutral, or appreciating sentences. Twenty BPD patients and 20 healthy controls rated their emotional responses to these on pleasantness, arousal, and 11 specific emotions. In addition to elevated reactivity to negative E.Vids, patients with BPD showed marked reduction in pleasantness responses to positive E.Vids. Furthermore, they exhibited less pride, happiness, feelings of approval, and attraction/love in response to positive videos and more anger, anxiety, embarrassment, contempt, guilt, feelings of disapproval/rejection, and sadness to negative videos. Interestingly, BPD patients also reported negative emotions in response to positive videos. Implications for psychotherapy and research are discussed.

Mapping Soil hydrologic features in a semi-arid irrigated area in Spain

Science.gov (United States)

Jiménez-Aguirre, M.° Teresa; Isidoro, Daniel; Usón, Asunción

2016-04-01

The lack of soil information is a managerial problem in irrigated areas in Spain. The Violada Irrigation District (VID; 5234 ha) is a gypsic, semi-arid region in the Middle Ebro River Basin, northeast Spain. VID is under irrigation since the 1940's. The implementation of the flood irrigation system gave rise to waterlogging problems, solved along the years with the installation of an artificial drainage network. Aggregated water balances have been performed in VID since the early 1980's considering average soil properties and aggregated irrigation data for the calculations (crop evapotranspiration, canal seepage, and soil drainage). In 2008-2009, 91% of the VID was modernized to sprinkler irrigation. This new system provides detailed irrigation management information that together with detailed soil information would allow for disaggregated water balances for a better understanding of the system. Our goal was to draw a semi-detailed soil map of VID presenting the main soil characteristics related to irrigation management. A second step of the work was to set up pedotransfer functions (PTF) to estimate the water content and saturated hydraulic conductivity (Ks) from easily measurable parameters. Thirty four pits were opened, described and sampled for chemical and physical properties. Thirty three additional auger holes were sampled for water holding capacity (WHC; down to 60 cm), helping to draw the soil units boundaries. And 15 Ks tests (inverse auger hole method) were made. The WHC was determined as the difference between the field capacity (FC) and wilting point (WP) measured in samples dried at 40°C during 5 days. The comparison with old values dried at 105°C for 2 days highlighted the importance of the method when gypsum is present in order to avoid water removal from gypsum molecules. The soil map was drawn down to family level. Thirteen soil units were defined by the combination of five subgroups [Typic Calcixerept (A), Petrocalcic Calcixerept (B), Gypsic

En este trabajo se exploró el uso de medios para la propagación de las variedades Quebranta, Negra Criolla, Albilla, Italia y Torontel, así como para el enraizamiento de las variedades Quebranta, Albilla y Torontel, a partir de los medios estándares reportados en la literatura científica. Para ello, se pusieron a prueba 11 variantes del medio estándar de propagación de vid (medio Murashige y Skoog 1X, 3% de sucrosa, 1 mg/L de benzilaminopurina y 0,8% de agar en las que se combinaron reducciones en la fuerza del medio con reducciones en la concentración de hormona. Para el enraizamiento posterior, se probaron el ácido naftalen acético y el ácido indol acético a 5 concentraciones distintas por cada hormona. Los resultados mostraron que el mejor medio para la propagación de las variedades Quebranta, Albilla e Italia es el estándar; las variedades Negra Criolla y Torontel tuvieron mejor desempeño con una reducción de la concentración de benzilaminopurina a 0,25 y 0,5 mg/L, respectivamente. El mejor enraizamiento en la variedad Quebranta ocurrió con 80 μg/L de ácido naftalen acético y 2 mg/L de ácido indol acético; las variedades Albilla y Torontel tuvieron una mejor respuesta al ácido indol acético a concentraciones de 2 y 1 mg/L, respectivamente.The protocols and culture media available for in vitro propagation and rooting of grapevine have not yet been adjusted to the creole varieties used for pisco making.

Full Text Available Maintaining grey matter within the hippocampus is important for healthy cognition. Playing 3D-platform video games has previously been shown to promote grey matter in the hippocampus in younger adults. In the current study, we tested the impact of 3D-platform video game training (i.e., Super Mario 64 on grey matter in the hippocampus, cerebellum, and the dorsolateral prefrontal cortex (DLPFC of older adults. Older adults who were 55 to 75 years of age were randomized into three groups. The video game experimental group (VID; n = 8 engaged in a 3D-platform video game training over a period of 6 months. Additionally, an active control group took a series of self-directed, computerized music (piano lessons (MUS; n = 12, while a no-contact control group did not engage in any intervention (CON; n = 13. After training, a within-subject increase in grey matter within the hippocampus was significant only in the VID training group, replicating results observed in younger adults. Active control MUS training did, however, lead to a within-subject increase in the DLPFC, while both the VID and MUS training produced growth in the cerebellum. In contrast, the CON group displayed significant grey matter loss in the hippocampus, cerebellum and the DLPFC.

Video-based multimedia designs: A research study testing learning effectiveness

Directory of Open Access Journals (Sweden)

David Reiss

2008-05-01

Full Text Available This paper summarizes research conducted on three computer-based video models’ effectiveness for learning based on memory and comprehension. In this quantitative study, a two-minute video presentation was created and played back in three different types of media players, for a sample of eighty-seven college freshman. The three players evaluated include a standard QuickTime video/audio player, a QuickTime player with embedded triggers that launched HTML-based study guide pages, and a Macromedia Flash-based video/audio player with a text field, with user activated links to the study guides as well as other interactive on-line resources. An assumption guiding this study was that the enhanced designs presenting different types of related information would reinforce the material and produce better comprehension and retention. However, findings indicate that the standard video player was the most effective overall, which suggests that media designs able to control the focus of a learner’s attention to one specific stream of information, a single-stream focused approach, may be the most effective way to present media-based content. Résumé: Cet article résume une étude vérifiant l’efficacité de l’apprentissage basé sur la mémorisation et la compréhension, conduite à partir de trois modèles basés sur la vidéo informatisée. Dans cette étude quantitative, une vidéo de deux minutes a été créée et lue sur trois types de lecteurs différents, pour un échantillon de 87 étudiants universitaires de première année. Les trois lecteurs évalués comprenaient un lecteur standard audio/vidéo Quicktime, un lecteur Quicktime avec déclencheurs intégrés qui lançait un guide d’étude en HTML, et un lecteur audio/vidéo Flash Macromedia avec un champ texte, comprenant des liens activés par l’usager vers des guides d’étude et d’autres ressources interactives en ligne.

Full Text Available As a result of the associated problems to evaluate bonding characteristics of interfaces between dissimilar metals, mainly those cladded, it has been propposed the use of ultrasonic methods. Acoustic impedance methods had been tested succesfully in the study of plastic-aluminium (glued and babbit-steel (bearing interfaces. Preliminary results on explosively bonded aluminium-steel and aluminium-lead interfaces are presented. A digital ultrasonic device with a 5 Mhz transducer was used in this study. So far, results have shown that "VID" signal gives an acceptance criterion based on the ratio of amplitudes coming from interface and bottom surface, meanwhile "RF" signal gives the same criterion based on wave form. It is concluded that VID and RF signals could be used to achieve characteristics of the bonded interfaces.

Como resultado de las dificultades encontradas para determinar las características de la intercara entre uniones de materiales disímiles, sobre todo aquellas empleadas en los recubrimientos, surge la posibilidad de emplear las técnicas de ultrasonido. Las técnicas basadas en la diferencia de impedancia acústica se han usado de manera exitosa para caracterizar las intercaras plástico-aluminio (adheridas y metal babbit-acero (en cojinetes. En este estudio se analizan, de manera preliminar, las intercaras de pares aluminio-acero y aluminio-plomo obtenidos por medio de soldadura por explosivos. Se utilizó un sistema de adquisición de señales digitales ultrasónicas y un transductor de 5 MHz. Los resultados obtenidos hasta el momento indican que la representación de la señal en forma de "VID" proporciona un criterio de aceptación basado en la relación entre las amplitudes de la intercara y la superficie posterior, mientras que la señal de "RF" proporciona un criterio de aceptación basado en la forma de la onda. Se concluye que es posible emplear las señales VID y RF para establecer criterios de aceptación de la uni

Full Text Available The flavonoid-rich active compound in grapes is claimed to be one of the most important natural products. Hence, the objective of our research was to study parameters of the prooxidative-antioxidative balance in athletes supplied with Panace-Vid 2000® preparation consisting of black wine grape extract (Vitis vinifera. The study was carried out on 22 male rowers. The subjects from the supplemented group (n=10 were given one gelatin capsule containing Panace-Vid 2000® three times a day, for six weeks, while the control group (n=12 was given placebo. Before and after the supplementation period, the athletes performed a physical exercise test on the rowing ergometer; varying between 40 and 90% of maximal aerobic power. Each 3-min exercise session was followed by thirty seconds of rest. Blood was sampled from the rowers before the exercise test, one minute after its completion, and after a 24-h recovery period. The activity of antioxidative enzymes (superoxide dismutase, glutathione peroxidase was determined and the concentration of thiobarbituric acid-reactive substances was measured in the hemolysate of red blood cells. The Total Antioxidant Capacity was determined in the blood plasma. The concentration of lactic acid was measured in the whole blood. An analysis of the results revealed that the supply of grape extract, in the form of Panace-Vid 2000® preparation, contributed to a significant increase in plasma antioxidative capacity and to an insignificant increase in superoxide dismutase, as well as a lower activity of glutathione peroxidase and reduced concentration of lipid peroxidation product levels.

Examining the Use of Lecture Capture Technology: Implications for Teaching and Learning

Jovan F. Groen

2016-06-01

Full Text Available This study sought to provide a better understanding of how lecture capture technology is used by students and how its use is related to student satisfaction, attendance, and academic performance. Using a mixed method design with both quantitative and qualitative methods to collect data, instruments included a student questionnaire, interviews and focus groups, lecture capture usage statistics, and grades. Results showed that 63% of students were satisfied with lecture capture and 75% of students indicated that it had facilitated their learning. Students primarily used the recordings to learn what they had missed while in class (79% or because they were absent (72%. 70% of students reported having watched at least 50% of the recorded material (27% watched all the material, and only 8% of students did not view any recordings. Student satisfaction had a significant positive relationship with the number of lectures viewed. In regards to attendance, the self-reported data from students indicated that 61% of students did not miss classes (none or just one class. Students with the greatest number of missed classes viewed the recordings more frequently. As for student achievement, 68% of students indicated that lecture capture helped them to achieve better grades. Students with lower course marks accessed the recordings more frequently than those with higher marks. Instructor perceptions were that lecture capture predominately helped average to below average students achieve slightly better marks, but had less of an impact on the grades for particularly low and high achieving students. Cette étude avait pour but de fournir une meilleure compréhension de la manière dont la capture de cours en vidéo est utilisée par les étudiants et comment son utilisation est reliée à la satisfaction des étudiants, à leur assiduité et à leurs résultats académiques.

Using video in teacher education

Directory of Open Access Journals (Sweden)

Jo Towers

2007-06-01

Full Text Available This paper draws on a research study of elementary- and secondary-route preservice teachers in a two-year, after-degree teacher preparation programme. The paper includes excerpts of classroom data, taken from the author’s own university classroom, demonstrating preservice teachers’ responses to carefully selected video extracts of children learning mathematics in a high-school class also taught by the author. The paper includes commentary on some of the advantages and limitations of video as a teaching tool, develops an argument for the increased use, in both preservice teacher education and inservice teacher professional development, of videotaped episodes that focus on the learners rather than on the classroom teacher, and explores the value of having the teacher whose classroom is featured on the videos present for the discussion of the episodes. The paper explores the potential offered by video material to foster the belief that teaching is a learning activity by (i refocusing attention on the learner rather than the teacher in the analysis of classroom practices, (ii raising awareness of the importance of reflective practice, and (iii providing a prompt for the imaginative rehearsal of action.

Full Text Available With the purpose of characterizing the growth of the root system of table grapes (Vitis vinifera L. cv. Thompson Seedless and its relationship with soil temperature, research was carried out during the 2004-2005 growing season in vineyards in the Copiapó and Huasco Valleys. Four plants were chosen and rhizotrons were used to measure the growth of the root system. Measurements were performed once a week from September 2004 to September 2005, estimating the intensity of root growth and its annual distribution in the ranges of 0 to 40, 40 to 80 and 80 to 120 cm of soil depth. Temperature sensors were installed in four plants at 25, 50, 75 and 100 cm of soil depth, and the temperature was registered every 1 h. The thermal diffusivity of the soil was calculated based on the annual mean temperature and annual thermal amplitude values. Root growth occurred throughout the year, presenting lower intensity in July (winter. Root systems presented different patterns in the distribution of growth intensity in the three soil depths, with variations in the order of five times in maximum annual growth intensity among sites. High thermal diffusivity in soils favored root growth.Con el objetivo de caracterizar el crecimiento del sistema radical de la vid (Vitis vinifera L. cv.

China's healthcare system often struggles to meet the needs of its 900 million people living in rural areas due to major challenges in preventive medicine and management of chronic diseases. Here we address some of these challenges by equipping village doctors (ViDs) with Health Information Technology and developing an electronic health record (EHR) system which collects individual patient information electronically to aid with implementation of chronic disease management programs. An EHR system based on a cloud-computing architecture was developed and deployed in Xilingol county of Inner Mongolia using various computing resources (hardware and software) to deliver services over the health network using Internet when available. The system supports the work at all levels of the healthcare system, including the work of ViDs in rural areas. An analysis done on 291,087 EHRs created from November 2008 to June 2011 evaluated the impact the EHR system has on preventive medicine and chronic disease management programs in rural China. From 2008 to 2011 health records were created for 291,087 (26.25%) from 1,108,951 total Xilingol residents with 10,240 cases of hypertension and 1152 cases of diabetes diagnosed and registered. Furthermore, 2945 hypertensive and 305 diabetic patients enrolled in follow-up. Implementing the EHR system revealed a high rate of cholecystectomies leading to investigations and findings of drinking water contaminated with metals. Measures were taken to inform the population and clean drinking water was supplied. The cloud-based EHR approach improved the care provision for ViDs in rural China and increased the efficiency of the healthcare system to monitor the health status of the population and to manage preventive care efforts. It also helped discover contaminated water in one of the project areas revealing further benefits if the system is expanded and improved. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

Comportamiento isohídrico o anisohídrico en vides…. ¿Una controversia sin fin?

Full Text Available De acuerdo al tipo de respuesta estomática, muchas especies han sido clasificadas como isohídricas o anisohídricas. Las plantas isohídricas son aquellas que cierran sus estomas cuando sensan una caída en el potencial hídrico del suelo, o un aumento en la demanda atmosférica. Al contrario, las plantas anisohídricas no cierran sus estomas y continúan transpirando aun cuando el contenido hídrico del suelo disminuya. Como consecuencia, su potencial hídrico foliar (ΨL cae, y la planta sufre estrés hídrico. En general, se considera que la vid es una planta que evita el estrés hídrico mediante un manejo estomático eficiente. Sin embargo, algunas variedades han mostrado tener un control más estricto que otras. Por esto, algunas variedades pueden ser clasificadas como isohídricas o anisohídricas. Actualmente, esta clasificación se encuentra bajo gran controversia debido a que muchas variedades clasificadas de una manera, mostraron comportamientos opuestos según diferentes situaciones ambientales, climáticas y edáficas. En consecuencia, muchos autores opinan que para variedades de vid esta clasificación no es correcta ni rigurosa.

The LEADER program in Hungary and in Europe A LEADER program Magyarországon és Európában

Directory of Open Access Journals (Sweden)

Bogár ESZTER

2011-11-01

Full Text Available The LEADER program is extremely complex, therefore adequate program leading is vital. On the evidence of the half-time evaluation report, serious shortcomings have been observed. The evaluation work has also been carried out in an unorganized way by the Local Action Teams, hereinafter called ‘HACS’. There was hardly a precedent for cooperation; national networks did not play an important role. Self assessment has rarely been followed by correction steps. The upward approach was taken into account while selecting HACS and carrying out the program’s other stages, although in most parts of the region (for instance in Portugal and Greece hidden possibilities were not fully put to account. The hitch in the upward approach might have been caused by the lack of downward support. It must be considered to be a negative fact that in consequence of the exclusion of the country towns, the maximum resident threshold (100,000 by local action teams has prevented the establishment of contiguous LEADER area. Although deviation was permitted, the mentioned threshold has been criticized several times because it limits the implementation of sale initiatives in some well developed parts of the country. As for the effect on broadening the knowledge of cooperation and network building, there are numerous signs in some countries like Ireland, Finland and Austria, that the LEADER approach, forwarding the information to other interested country parties, facilitates integrated country development. For my further analysis my plan is to gather information about certain stages of the LEADER and the temporary work of the local action teams from various countries. I would like to find the most optimal index for each action team respectively their support and their achieved work.Mindennapi életünk folyamán is gyakran halljuk az alábbi szavakat: LEADER, Európai Falu, vidékfejlesztés, falusi turizmus, kulturális örökségek védelme… de mi áll ennek h

Behaviour of reindeer as an indicator of an adaptation to feeding

Directory of Open Access Journals (Sweden)

Anna Nilsson

2004-04-01

Full Text Available Abstract: We assessed behaviour of reindeer affected by nutritional deprivation and how they adapted to various feeding strategies. The activity pattern of 61 penned eight month old female reindeer calves was observed during 20 of a total of 42 experimental days in winter 1997. The dominant activities were lying, ruminating, intake of feed and water, and standing. Few recordings of agonistic behaviour or snow intake occured. Restricted feed intake, half the ad lib. ration of a lichen-based diet, affected the eating behaviour of the reindeer, and more animals were standing and fewer lying compared to reindeer fed ad lib. Lack of energy in the diet correlated with animals lying curled up (lying with the muzzle close to the hind legs. This behaviour could be a useful complement to other measurements and registrations when studying adaptations to various feeding regimens.Abstract in Swedish/Sammanfattning:Syftet med studien var att undersöka om, och i så fall hur renars beteende påverkades av otillräckligt näringsintag och vid anpassning till olika utfodringsstrategier. Aktivitetsmönstret hos 61 inhägnade åtta månader gamla honrenkalvar studerades under 20 av totalt 42 försöksdagar. De vanligaste beteendekategorierna genom hela försöket var ligga, idissla, intag av foder och vatten samt stå passivt. Endast ett fåtal observationer av aggressivt beteende och snöätande registrerades. En begränsad giva dvs. halva mängden av fodergivan vid fri tillgång av en lavbaserad diet påverkade djuren ätbeteende. Dessutom observerades fler djur stå passivt medan färre låg jämfört med kontrollgruppen. Under första fasen av utfodring efter restriktionsperioden låg fler djur låg ihoprullade (med mulen tätt intill bakbenet jämfört med kontrollgruppen, vilket tolkades som ett tecken på energibrist. Beteendestudierna visade sig vara ett värdefullt komplement till övriga mätningar och provtagningar vid studier av renars anpassning till

Torres, Ester

2005-12-01

Full Text Available Among grapevine yellows phytoplasma diseases in Europe, flavescence dorée (FD is the most devastating and in the last decade has reached Spanish vineyards, mainly in Catalonia. An eight-year survey was carried out in the areas where the disease has spread (Alt Empordà, Catalonia, Northern Spain and in the remaining vine-growing areas of Catalonia. Sequence analyses of a portion of the 16S-23S ribosomal DNA cistron, from selected grapevine samples from Catalonia, showed that the phytoplasmas involved in grapevine yellows belong to 16S ribosomal subgroups V-D (flavescence dorée, FD and XII-A (bois noir, BN. A set of Spanish FD isolates collected during these years were further studied by RFLP analyses of the 16S-23S ribosomal DNA fragment, as well as the rpS3 and SecY genes. All the FD phytoplasma strains studied were related to phytoplasmas belonging to ribosomal protein subgroup rp-E.La flavescencia dorada (FD es la enfermedad más agresiva de entre todas las enfermedades de fitoplasmas que causan amarilleos de vid en Europa, y que en la última década ha alcanzado también a los viñedos de España, principalmente en Cataluña. Se ha realizado un seguimiento durante ocho años en las zonas donde la enfermedad se había difundido (Alt Empordà, Cataluña y en el resto de zonas con cultivo de vid de Cataluña. El análisis del fragmento del gen DNA ribosomal 16S-23S, de una selección de muestras de vides de Cataluña, indica que los fitoplasmas que están implicados en los amarilleos de vid pertenecen a los subgrupos ribosomales 16S V-D (flavescencia dorada, FD y XII-A (bois noir, BN. Una selección de aislados españoles de FD obtenidos durante estos años se ha examinado mediante análisis RFLP del fragmento del gen ribosomal 16S-23S, y de los genes rpS3 y SecY. Todos los aislamientos de fitoplasmas FD estudiados están relacionados con fitoplasmas pertenecientes al subgrupo de proteína ribosomal rp-E.

Differing Roles of the Face and Voice in Early Human Communication: Roots of Language in Multimodal Expression

2017-09-01

Full Text Available Seeking roots of language, we probed infant facial expressions and vocalizations. Both have roles in language, but the voice plays an especially flexible role, expressing a variety of functions and affect conditions with the same vocal categories—a word can be produced with many different affective flavors. This requirement of language is seen in very early infant vocalizations. We examined the extent to which affect is transmitted by early vocal categories termed “protophones” (squeals, vowel-like sounds, and growls and by their co-occurring facial expressions, and similarly the extent to which vocal type is transmitted by the voice and co-occurring facial expressions. Our coder agreement data suggest infant affect during protophones was most reliably transmitted by the face (judged in video-only, while vocal type was transmitted most reliably by the voice (judged in audio-only. Voice alone transmitted negative affect more reliably than neutral or positive affect, suggesting infant protophones may be used especially to call for attention when the infant is in distress. By contrast, the face alone provided no significant information about protophone categories. Indeed coders in VID could scarcely recognize the difference between silence and voice when coding protophones in VID. The results suggest that partial decoupling of communicative roles for face and voice occurs even in the first months of life. Affect in infancy appears to be transmitted in a way that audio and video aspects are flexibly interwoven, as in mature language.

Goldschmidt, Barbara; Nordling Magnus

2003-02-01

This project is the first part of a larger project. In the part reported here, materials for flue gas condensers have been investigated by contact with plant owners and suppliers and by a literature review of reported failures. If it is decided to continue with another part of the project, a number of materials will be long term tested on site. The project is complementary to an earlier project, which investigated the operating experiences from flue gas condensers in biomass fired cogeneration plants. In the project materials (steel and polymeric) suitable for long term testing in existing plants are discussed. It is proposed that testing in the second part of the project is made with material coupons in one plant fired with only biomass and one plant where biomass is co fired with other fuels. In the biomass fired plant a number of steel materials should be tested. In the co fired plant, with its harsher operating conditions, the same steel materials plus a number of polymeric materials should be tested. Materials suitable for testing are summarised in the report.

An alternative to the TEM (Transformed Eulerian Mean) equations

Science.gov (United States)

Gaßmann, Almut

2013-04-01

The TEM equations constitute a powerful means to get access to the residual circulation. However, due to their foundation on the wave perspective, they deliver only a zonally averaged picture without access to the three-dimensional structure or the local origins of the residual circulation. Therefore it is worth to investigate whether there are alternatives. The pathway followed here is to perform a transformation of the momentum and the potential temperature equation before taking the zonal mean. This is done by removing the steady state ideal wind solution vid = ?×?B-(?±P) from the equations (? - potential temperature, B - Bernoulli function, P - Ertel's potential vorticity EPV, ?± - density). The advantage of that approach is that the total EPV-flux does no longer contain an explicitly visible 'do-nothing-flux'. This flux, ?? ×?B, does only vanish when averaging on isentropic surfaces, but not on other isosurfaces. Here we find the reason why the conventional zonal mean on isentropes delivers a direct overturning cell on each hemisphere, whereas on other isosurfaces we obtain the typical three-cell structure with Headley, Ferrel, and polar cells. It will be demonstrated and made visible through idealized climate experiments with the ICON-IAP model that the zonal averages of the nonideal wind components vnid = v - vid and wnid = w - wid constitute similar direct overturning cells on non-isentropic surfaces as obtained with the TEM-generated v* and w*. It is also interesting to inspect fields of local nonideal wind components, the very origin of the residual circulation.

Full Text Available The effects of P and K on grapevines (Vitis vinifera L. var. Muscat Rosada were evaluated four years, considering the same levels of N. The experiment was conducted at the Vicuña Experimental Station (30° S; 70°44´ W of the Instituto de Investigaciones Agropecuarias (INIA. The soil is alluvial antropic miscellaneous (Entisols. Three fertilization treatments were established: 1 N 160 + P2O5 200 + K2O 300; 2 N 160 + P2O5 0 + K2O 300; and 3 N 160 + P2O5 200 + K2O 0. At the beginning of the experiment, grape vines received all the phosphate fertilizers, 200 kg ha-1 of P2O5 as triple superphosphate in Treatments 1 and 3. Nitrogen was applied as urea for four years. The applications were initiated when the vine buds measured 20 cm. The K was applied to the soils of Treatments 1 and 2, at a dosage of 200 kg ha-1 K2O, using potassium sulphate. Between berry set and 30 d before harvest, 100 kg ha-1 K2O were applied as potassium sulphate by fertigation. Significant effects of the P fertilization were observed by the second year, with increased cluster numbers per plant. K also increased grape fruit yield by the third year. This response was obtained with less than 5 mg kg-1 of P available in the soil and less than 145 mg kg-1 of exchangeable K in the soil. The initially low content of available K and P suggests a high probability of response to the application of both elements.En el Campo Experimental del Instituto de Investigaciones Agropecuarias (INIA, ubicado en la localidad de Vicuña (30° S; 70°44´ O, se evaluó durante cuatro años el efecto de la aplicación de P y K, considerando un mismo nivel de aplicación de N en vid (Vitis vinifera L. var.

Syfte: Studiens syfte är att förklara hur revisorernas väsentlighetsbedömningar påverkas av klientens branschtillhörighet. Metod: Studien har ett ...

Den 1 Mars 2006 ersattes den gamla UtlL (1989:529) av en ny UtlL (2005:716) med stora förändringar i instans- och processordningen. De grundläggande kraven på denna var att öppenheten i asylprocessen skulle öka, att de sökande skulle ges ökade möjligheter till muntlig förhandling vid överklagande av asyl- och medborgarskapsärenden, att processen skulle bestå av en tvåpartsprocess och att instans- och processordningen skulle utformas så att kraven på skyndsam handläggning uppfylldes.

Evidensgraderingssystemet GRADE : Ett sätt att granska vetenskaplig kunskap om metoder och arbetssätt i hälso- och sjukvården

OpenAIRE

Roback, Kerstin; Carlsson, Per

2009-01-01

Beslut om införande av nya behandlingsmetoder och arbetssätt i sjukvården präglas alltid av en viss grad av osäkerhet. De studier som gjorts av metodens för- och nackdelar kan vara av olika god kvalitet och därmed ge mer eller mindre säkra resultat. Efter att användningen av systematiska litteraturstudier vid medicinsk teknologiutvärdering tog fart på 1980-talet började man efterfråga ett beslutsunderlag som även tar hänsyn till olika studiers kvalitet. Detta initierade utvecklingen av flera ...

Vindkraftverk av UHPC 2.2 : En undersökning av högpresterande betong med syntetfiberarmeringen STRUX

OpenAIRE

Rydén, Michaéla; Nilsson, Thina

2013-01-01

Användandet av betong som ersättare för stål vid produktionen av vindkraftverkstorn har ökat den senaste tiden. Betongtorn är betydligt billigare än ståltorn men problem som sprickbildningar, frostsprängningar och följaktligen armeringskorrosion har uppstått bl a på grund av vibrationer från rotorn. I fundamentet i vindkraftverk kan ovan nämnda problem också uppstå och det uppfyller således inte alltid funktionskraven. Det här examensarbetet undersöker möjligheten att eliminera dessa problem ...

Lagerskador kontra centralsmörjningssystem

OpenAIRE

Egestrand, Jens

2012-01-01

Examensarbetet som har genomförts på uppdrag av Stora Enso belyser svårigheter kring övervakning av lagerkondition och korta lagerlivslängder i presspartien på kartongmaskinerna. Arbetet belyser även om de korta lagerlivslängderna är smörjrelaterade och hur smörjmedlet påverkar lagerlivslängden. Det finns problematik med att finna lagerfel vid användning av vibrationsanalys på relativt lågvarviga maskiner, detta beror på den låga energinivån som genereras av en lagerdefekt och därmed döljs la...

2009-01-01

Vid en granskning av nickelhalter för perioden 1985-2007 upptäcktes ett nivåskifte i tidsserierna på flera stationer mellan 2001 och 2002.

OpenAIRE

Nyström, Martin; Wahlman, Anna

2005-01-01

Bakgrund: Flygtransportbranschen är hårt konkurrensutsatt genom stark etablering av lågprisbolag. Därtill har händelser såsom terrordådet i New York och SARS påverkat marknaden negativt; branschen har dessutom drabbats av förändrat kundbeteende, bland annat hos privatkunder, och flygbolagen finner det allt svårare att förutse kundernas köp. En medvetenhet om att resenärerna ser priset som en primär faktor vid val av flygbolag finns, men det har visat sig svårt att identifiera andra faktorer. ...

Head movements and postures as pain behavior

Science.gov (United States)

Al-Hamadi, Ayoub; Limbrecht-Ecklundt, Kerstin; Walter, Steffen; Traue, Harald C.

2018-01-01

Pain assessment can benefit from observation of pain behaviors, such as guarding or facial expression, and observational pain scales are widely used in clinical practice with nonverbal patients. However, little is known about head movements and postures in the context of pain. In this regard, we analyze videos of three publically available datasets. The BioVid dataset was recorded with healthy participants subjected to painful heat stimuli. In the BP4D dataset, healthy participants performed a cold-pressor test and several other tasks (meant to elicit emotion). The UNBC dataset videos show shoulder pain patients during range-of-motion tests to their affected and unaffected limbs. In all videos, participants were sitting in an upright position. We studied head movements and postures that occurred during the painful and control trials by measuring head orientation from video over time, followed by analyzing posture and movement summary statistics and occurrence frequencies of typical postures and movements. We found significant differences between pain and control trials with analyses of variance and binomial tests. In BioVid and BP4D, pain was accompanied by head movements and postures that tend to be oriented downwards or towards the pain site. We also found differences in movement range and speed in all three datasets. The results suggest that head movements and postures should be considered for pain assessment and research. As additional pain indicators, they possibly might improve pain management whenever behavior is assessed, especially in nonverbal individuals such as infants or patients with dementia. However, in advance more research is needed to identify specific head movements and postures in pain patients. PMID:29444153

Territorialisation à distance par caméra vidéo : Perception de la vidéosurveillance au quartier des Pâquis à Genève

Directory of Open Access Journals (Sweden)

F. Klauser

2017-07-01

Full Text Available Drawing upon two public opinion surveys conducted in Geneva in 2015 and 2016, the paper explores how video surveillance was lived and perceived by the residents of the monitored Pâquis area, as well as by the population at large. This study shows that the delegation of control to systems and individuals that are both spatially and socially detached from the monitored areas also results in a kind of `mental distance' that characterizes the relation between the monitored individuals and the system: People quickly forget about the cameras and withdraw from any conscious attempt to imagine what might be going on behind their back. The system thus gradually loses its relevance in people's everyday life. This, in turn, limits the symbolic power of the cameras to enduringly revitalize, and thus to properly re-territorialize, the monitored areas.

Views on quality assurance at Finnish and Swedish nuclear power plants and at Halden Reactor; Syn paa kvalitetssaekring vid finlaendska och svenska kaernkraftverk samt vid Haldenreaktorn

Energy Technology Data Exchange (ETDEWEB)

Hammar, L.; Lidh, B. [ES-konsult (Sweden); Wahlstroem, B.; Reiman, T. [VTT Automation (Finland)

2001-06-01

The paper reports on a study within the Nordic Nuclear Safety Research, NKS on quality systems at nuclear installations in Finland, Norway and Sweden. In the study a total of 74 people at the NPPs in Barsebaeck, Forsmark, Loviisa, Olkiluoto, Oskarshamn and Ringhals, and at the research reactor in Halden were interviewed in the period 30 August to 13 December 2000 concerning their views in regard of quality and quality systems. The study was concluded with a seminar held in the Ringhals nuclear power plant in Januar 2001. The study covered a number of aspects in regard of quality management, including the quality concept, quality systems, topical quality issues and approaches, rules and procedures, competency and training, the process approach to quality management, the promotion of quality consciousness and future prospects. The study reflects the significant progress made in the management of quality in nuclear power in the Nordic countries since the early phase in the seventies. The most distinctive characteristic of today's approach to quality is seen in that responsibility for the quality is assumed directly in conjunction with the working processes. It could be noted that the work patterns at the nuclear installations have been largely modified during the recent years as a result of persistent endeavours to continuously improve the quality of operation. Challenges were seen in currently reduced revenues due to descending electricity prices and the likely prospect of further increased regulatory safety requirements. The report is aimed for those working with quality issues at the nuclear power plants as well as for those interested in quality management in general or in the safety aspects of nuclear power in particular.

District Heating at Power Failures - Final Report; Fjaerrvaerme vid Elavbrott - Slutrapport

Energy Technology Data Exchange (ETDEWEB)

Lauenburg, Patrick; Johansson, Per-Olof

2008-11-15

Our society is vulnerable to prolonged power cuts. In cold weather interrupted heating is one of the most serious threats. District heating is available at most locations in Sweden and if heat can be transferred to the connected buildings at a power failure, it is of great importance for securing energy supply. In this work it was found that there are good opportunities for upholding heat supply at a power failure through self-circulation in connected radiator system, which has previously been overlooked. Self Circulation occurs when there is a sufficiently large temperature difference between forward and return line in the radiator system. The control and circulation in radiator systems will fail, but if the district heating water can continue to pass through the heat exchangers of the radiator systems self-circulation can occur. A prerequisite for self-circulation in the individual buildings to work is therefore to district heating network can operate at a power failure. District heating supply must have back to maintain the production and distribution of district heating, which is not always the case. Our studies show that there is every reason to this. Moreover there are customers that have their own reserve aggregates, such as hospitals, which are dependent on the district heating network function. In an extensive power failure, it may be desirable to establish a smaller grid, separate from backbone, using local electricity generation. The establishment of such a network requires there is local production which can start to loose voltage networks and has necessary control equipment for the frequency approach. In Malmoe, it is now possible to establish a such a network with the help of local production units. A prerequisite is that there are consumption of heating. It is not unusual for power plants (which produce both electricity and heat) is dependent on the pipe system for cooling the production of electricity. One can from the results also argue that every district should have cogeneration for a security of supply. The results show that the vast majority of buildings can be self-circulation in a power failure equivalent to 40-80 percent of the warming effect. Hot water systems covered primarily not of this, even if some hot water production can be possible. Self-circulation works better the higher the ambient temperature is. However, most buildings, possibly after some modifications, have at least 50 percent of the warming impact at a very low ambient temperature, which means that you normally do for several days before a possible evacuation becomes necessary. The studies have enabled a number of recommendations have been compiled. The recommendations are designed to increase opportunities for self-circulation of different systems and is addressed to all parties concerned, i.e. from authorities and district heating companies to manufacturers, building owners, operators and residents, and includes both preparatory steps and these actions can be taken when a power failure has been occurred. Finally, we note that there should be a value in the form of the presented results are a selling point for the district and the societal costs of example, reserve units and possible evacuations can be reduced

Planering, progression, profession: hur studenter blir planerare

Directory of Open Access Journals (Sweden)

Lars Larsson

2017-09-01

Full Text Available De kunskaper som utvecklas med stöd i de nationella examensmålen för värderingsförmåga och förhållningssätt är de som ligger närmast den professionella identiteten. Denna kunskapskategori ges begränsat utrymme i de förväntade studieresultat som examineras inom samhällsplanerarprogrammet vid Umeå universitet. Trots detta får studenterna anställning som planerare, ofta kort efter att de tagit sin kandidatexamen. Syftet med denna studie är därför att undersöka hur kunskapsmässig progression underbyggs avseende värderingsförmåga och förhållningssätt i en planerarutbildning med kulturgeografi som huvudområde. I denna artikel redovisas en analys av samhällsplanerarprogrammet.De kurser i kulturgeografi som ingår i programmet analyseras utifrån förväntade studieresultat, läraktiviteter och examinationsformer i syfte att spåra den planerade progressionen. Särskild uppmärksamhet ägnas kunskapskategorin värderingsförmåga och förhållningssätt. Resultaten diskuteras utifrån en modell för att förstå vilka typer av kunskaper som används vid avvägningar och beslut i planeringsprofessionen. Analysen visar att samhällsplanerarprogrammets planerade progression följer principen att först ge studenterna breda ämneskunskaper, därefter utveckla metodfärdigheter och mot slutet utveckla mer komplexa och handlingsinriktade kunskaper. Den visar också att den planerade progressionen är begränsad i att underbygga normativa aspekter av studenternas värderingsförmåga och förhållningssätt.

VICAR - VIDEO IMAGE COMMUNICATION AND RETRIEVAL

I/O, label I/O, parameter I/O, etc.) to facilitate image processing and provide the fastest I/O possible while maintaining a wide variety of capabilities. The run-time library also includes the Virtual Raster Display Interface (VRDI) which allows display oriented applications programs to be written for a variety of display devices using a set of common routines. (A display device can be any frame-buffer type device which is attached to the host computer and has memory planes for the display and manipulation of images. A display device may have any number of separate 8-bit image memory planes (IMPs), a graphics overlay plane, pseudo-color capabilities, hardware zoom and pan, and other features). The VRDI supports the following display devices: VICOM (Gould/Deanza) IP8500, RAMTEK RM-9465, ADAGE (Ikonas) IK3000 and the International Imaging Systems IVAS. VRDI's purpose is to provide a uniform operating environment not only for an application programmer, but for the user as well. The programmer is able to write programs without being concerned with the specifics of the device for which the application is intended. The VICAR Interactive Display Subsystem (VIDS) is a collection of utilities for easy interactive display and manipulation of images on a display device. VIDS has characteristics of both the executive and an application program, and offers a wide menu of image manipulation options. VIDS uses the VRDI to communicate with display devices. The first step in using VIDS to analyze and enhance an image (one simple example of VICAR's numerous capabilities) is to examine the histogram of the image. The histogram is a plot of frequency of occurrence for each pixel value (0 - 255) loaded in the image plane. If, for example, the histogram shows that there are no pixel values below 64 or above 192, the histogram can be "stretched" so that the value of 64 is mapped to zero and 192 is mapped to 255. Now the user can use the full dynamic range of the display device to display

Studying cooling curves with a smartphone

Science.gov (United States)

Silva, Manuela Ramos; Martín-Ramos, Pablo; da Silva, Pedro Pereira

2018-01-01

This paper describes a simple procedure for the study of the cooling of a spherical body using a standard thermometer and a smartphone. Experiments making use of smartphone sensors have been described before, contributing to an improved teaching of classical mechanics, but rarely expand to thermodynamics. In this experiment, instead of using a smartphone camera to slow down a fast movement, we are using the device to speed up a slow process. For that we propose the use of the free app Framelapse to take periodic pictures (in the form of a time-lapse video) and then the free app VidAnalysis to track the position of the mercury inside the thermometer, thus effortlessly tracking the temperature of a cooling body (Fig. 1).

Efficient video delivery involves the transcoding of the original sequence into various resolutions, bitrates and standards, in order to match viewers 'capabilities. Since video coding and transcoding are computationally demanding, performing a portion of these tasks at the network edges promises to decrease both the workload and network traffic towards the data centers of media provid-ers. Motivated by the increasing popularity of live casting on social media platforms, in this paper we focus on the case of live vid-eo transcoding. Specifically, we investigate scheduling heuristics that decide on which jobs should be assigned to an edge mini-datacenter and which to a backend datacenter. Through simulation experiments with different QoS requirements we conclude on the best alternative.

Environmental impact at primary production of biofuels; Miljoeeffekter vid primaerproduktion av biobraenslen

Sweden has a policy objective that the forest and agricultural production of renewable energy must increase. Several of the traditionally cultivated annual crops can be used to biofuels, such as wheat, oilseed rape and sugar beet, but other crops are also interesting. Apart from an increase in Salix cultivation we discuss the cultivation of plants we have not cultivated, such as hemp, poplar and aspen, and intensive cultivation of spruce. Reed canary grass and grassland with several species are other candidates. The old reproductive systems environment are well known but what the new ones mean for the environment is poorly known. In this report, the state of knowledge regarding environmental impacts of primary bio-fuel production in Sweden is compiled. Based on the assumption that the reference crop is a plowed field the crops that can be grown on agricultural land are discussed. For the forest soil analyzed GROT (Tree-branches and -tops), root harvesting and intensive farmed spruce. The environmental impacts treated are carbon sinks in soil, compaction (with accompanying erosion problems), nutrient leaching, pesticides, landscape diversity, and biodiversity. One conclusion of the study is that it generally that there are many positive environmental effects of converting agricultural land to perennial crops for bioenergy, at least to some degree. On the other hand, increased collection of primary bio-energy from forests has mainly negative environmental impacts. The size of the effects are strongly linked to how much and where to grow and harvest, so a study of scale problems should be urgently implemented. This applies to both nutrient leaching and on the biological and landscape diversity. Use of ecosystem- and geographic models can be effective tools to generate different scenarios. The greatest potential of all crops, however, appears to be for aquatic systems with harvest of blue-green algae and bacteria, which probably would have mainly positive effects on the eutrophied lakes from which they were harvested. No such studies exist, however. Studies of techno-economic character are need in this area

Bird Survey in Storruns windfarm in Jaemtland; Faagelundersoekning vid Storruns vindkraftanlaeggning Jaemtland

A survey of the bird populations in Oldfjaellen in Jaemtland county, Sweden, was initiated in 2003 prior to the construction of a wind-farm on two adjacent hills, Storrun and Froesoerun by the lake Oevre Oldsjoen. After a gap in the surveys in 2004, comprehensive studies were continued during 2005 - 2008, prior to the construction. The construction-work started during autumn 2008, and the turbines were erected during 2009. Power production was started during the autumn of 2009. The post-construction bird studies were carried out in 2010 and 2011. This report summarizes all the studies that were performed before and after the construction of the wind-farm. Many of the separate studies were made using a BACI method (Before-After-Control-Impact) enabling comparisons of the situation before and after development, using a control area. In addition, a study of collision rates and scavenger removal rates is reported. As expected, the movement and migration of birds over Storrun was of rather limited magnitude. Although the majority of observations during the investigated periods spring and autumn are assumed to be migrating birds, larger flocks of birds are rare in the area. Ca. 20 % of all the birds that passed through or near the wind-farm area flew in heights comparable to the rotor-swept zone. However, more than 40 % of the raptors and waders passed through in that zone, which implies a collision risk. These two groups of birds have shown to be particularly prone to collisions with rotor blades in other studies.

Automatisation of moisture content measurement in biofuel deliveries; Automatiserad fukthaltsmaetning vid braenslemottagning

Measurement of moisture content in biofuel is normally made through manual sampling near the surface of truck deliveries or in the bulk of fuel deliveries that is distributed on e.g. a storage area. Moisture content is usually performed trough gravimetric determination at lab using oven drying for 24 hours. Precision is approximately a standard deviation of 2 %-units. However, there are several reasons to replace this method by an automatic procedure that measures moisture content in the bulk of the cargo. Except for obtaining more representative samples in the bulk, are speed and the measurement cost important characteristics. The purpose of this project was to develop a well-functioning prototype of a system that is automatic in the sense that manual sampling and sample preparation is replaced by a Near Infra Red (NIR) based system. The intended users of such a system would be both buyers of biofuel and suppliers who would benefit from better knowledge of the quality of the product that they are about to deliver. This project was initiated in the late autumn of 2006. A complete hardware set-up including a NIR spectrophotometer, light probe and a crane was installed in June 2007 in Eskilstuna, Sweden, and shown to members of the reference group at Vaermeforsk. The reliability of reference data obtained through gravimetric measurement was unfortunately not as good as expected on beforehand. This problem was due to the difficulty of obtaining representative samples near the surface of the truck cargo. It delayed the validation phase of this project significantly. An evaluation of the NIR based system reveals a good accuracy and precision that is far better than that of the traditional method for delivery control. A major reason for the superior precision is that the sampling error is reduced. Further, the NIR based system delivers real-time moisture data with a speed that is difficult to reach at lab because of restrictions in manual labour and limitations in equipment capacity. This project has therefore fulfilled all goals that were initially set up. (author)

Kecklund, Lena [MTO Psykologi, Huddinge (Sweden)

2005-09-15

The Swedish nuclear power plants were commissioned during a period between 1972 and 1985 and the instrumentation and control equipment are basically from that period. For several years there have been plans made for changes in all the nuclear power plants and to a certain extent the changes in control equipment and monitoring rooms have also been implemented. The object of this project was to make a comprehensive review of the changes in control room design implemented in the Swedish nuclear power plants and to describe how the MTO- (Man-Technology-Organisation) and (Man-Machine-Interface) -issues have been integrated in the process. The survey is intended to give an overall picture of the changes in control room design and man-machine-interface made in the Swedish control rooms, in order to get a deeper knowledge of the change management process and its results as well as of the management of MTO-issues in these projects. The units included in this survey are: Oskarhamn reactor 2 and 3; Ringhals reactor 2, 3 and 4; Forsmark reactor 1, 2 and 3. The Oskarshamn 1 unit has not been included in this report as it has recently undergone an extensive modernisation program as well as a detailed inspection by the SKI (Swedish Nuclear Power Inspectorate). At Ringhals 2 the modernisation work is carried out at present and the unit is also subjected to extensive inspection activities carried out by SKI and is therefore not part of this survey. This report also includes a short description of relevant standards and requirements. Then follows a presentation of the results of the plant survey, presented as case studies for three companies OKG, Ringhals and FKA. Control room changes are summarized as well as the results on specific MTO issues which has been surveyed. In all the power companies there is a joint way of working with projects concerning plant modifications. This process is described for each company separately. In the concluding of the report the strengths and improvement areas defined in the survey are summarised.

Materials in flue gas condensation plants. Stage 2; Materialval vid roekgaskondensering. Etapp 2

Energy Technology Data Exchange (ETDEWEB)

Nordling, Magnus; Bergman, Gunnar; Baeck, Gustaf; Jacobsson, Karin; Pahverk, Helen; Roemhild, Stefanie

2004-12-01

The corrosion resistance of some metallic and polymeric materials has been investigated in the flue gas scrubbers/condensers in the power plants at Igelsta using waste wood and Brista using bio fuel in the boilers. The materials were exposed inside the inlet part of the condenser and inside the flue gas duct after the condenser. In Brista, the polymeric materials were also exposed to the hot flue gases inside the duct before the condenser. The temperature of the gases before and after the condenser in Brista was 140 deg C and 50-60 deg C, respectively. In Igelsta, the flue gas temperature after the condenser was 45 deg C. The metallic coupons in the condenser were located in the spray-zone, both in Igelsta and Brista. That was true also for the polymeric material in Brista. In both plants, the wash-solution had a pH of 7-8, a temperature of 30 deg C, and a low content of chloride. The metallic materials investigated were stainless steels of the following grades: 17-12-2.5, 2205, SAF2507 and 254SMO. The major part of the polymeric materials investigated consisted of FRP laminates, which were made with different combinations of resin type of surface veil and type of chopped strand mat (CSM). Laminates with a new type of vinyl ester resin, Atlac E-Nova FW 1045, a new type of a stress-corrosion-resistant glass-fibre called Arcotex, and two types of surface reinforcement of carbon fibre have been compared to laminates of common type. Laminates with a special reinforcement of the type 3-D fabric were also included as well as five polypropylene materials (PP) with varying degree of stabilisation, two glass-flake materials applied on carbon steel and a butyl rubber. The corrosion resistance of the materials was evaluated after seven a months exposure at the different positions in the plants. The stainless steel materials were evaluated with respect to uniform corrosion, pitting and crevice attack. The corrosion resistance of the polymeric materials was evaluated with different methods and techniques which varied depending on the type of material. The FRP and the glass-flake materials were evaluated using visual inspection, microscopic investigation of polished and dye-stained cross sections, determination of mass loss and thickness changes. The laminates were also subjected to mechanical testing. The PP materials were evaluated by so-called OIT determinations (Oxidation Induction Time) and the rubber material by determination of changes in elongation at break. The results showed that for all steel materials the uniform corrosion was very low in all positions. The corrosion rate was between 0.2 and 0.4 {mu}m/year, which suggests that they would perform well from a uniform corrosion resistance point of view. The only clear difference among the steels was that the weld of SAF2507 showed a higher frequency of pits than that in the weld of the other steels. It however ought to be pointed out that the metallic materials that were exposed in the inlet of the condenser, were not exposed in the probably most aggressive region, the so called wet-dry zone. If so, a difference regarding the degree of corrosion attack on the different materials might would have been the case. The results related to polymeric materials showed among other things that the new glass-fibre type, Arcotex, is not suitable to be used for laminates in the environments studied, because of a too low osmosis resistance which gave rise to damage in the form of microdelaminations and blistering. The new resin Atlac E-Nova FW 1045 showed a markedly less corrosion resistance to hot flue gases compared to the conventional ones based on Atlac 590 and Derakane 470. Compared to surface veil reinforcement made of glass and carbon fibre, the use of a woven fabric of carbon fibre in the surface layer seemed to generally improve the resistance of the laminate to the studied environments with respect to the retention of the mechanical properties. The glass-flake materials showed good corrosion resistance in all positions. The PP-materials showed good resistance to corrosion, but the stabiliser was consumed to varying extents depending on partly the temperature of exposure, partly on unknown factors. The butyl rubber showed good corrosion resistance, but also signs of ageing. When comparing metallic and polymeric materials, it can be concluded that all steels have performed well, but most polymeric materials have shown certain damage of varying degree and importance. The long-term corrosion resistance of the polymeric materials is, compared to metals, more complex to evaluate and assess. In particular, that is true when data is available only for one single exposure time. To predict how different forms of attack develop in time, corrosion analyses at different exposure times are required. [abstract truncated

The Cournot-Theocharis problem reconsidered

In 1959 Theocharis [Theocharis RD. On the stability of the Cournot solution on the oligopoly problem. Review of economic Studies 1959;27:133-4] showed that with linear demand and constant marginal costs Cournot equilibrium is destabilized when the competitors become more than three. With three competitors the Cournot equilibrium point becomes neutrally stable, so, even then, any perturbation throws the system into an endless oscillation. Theocharis's argument was in fact proposed already in 1939 by Palander [Palander T. Konkurrens och marknadsjaemvikt vid duopol och oligopol. Ekonomisk Tidskrift 1939;41:124-45, 222-50]. None of these authors considered the global dynamics of the system, which necessarily becomes nonlinear when consideration is taken of the facts that prices, supply quantities, and profits of active firms cannot be negative. In the present paper, we address the global dynamics.

Estimated emission reductions from California's enhanced Smog Check program.

Science.gov (United States)

Singer, Brett C; Wenzel, Thomas P

2003-06-01

The U.S. Environmental Protection Agency requires that states evaluate the effectiveness of their vehicle emissions inspection and maintenance (I/M) programs. This study demonstrates an evaluation approach that estimates mass emission reductions over time and includes the effect of I/M on vehicle deterioration. It includes a quantitative assessment of benefits from pre-inspection maintenance and repairs and accounts for the selection bias effect that occurs when intermittent high emitters are tested. We report estimates of one-cycle emission benefits of California's Enhanced Smog Check program, ca. 1999. Program benefits equivalent to metric tons per day of prevented emissions were calculated with a "bottom-up" approach that combined average per vehicle reductions in mass emission rates (g/gal) with average per vehicle activity, resolved by model year. Accelerated simulation mode test data from the statewide vehicle information database (VID) and from roadside Smog Check testing were used to determine 2-yr emission profiles of vehicles passing through Smog Check and infer emission profiles that would occur without Smog Check. The number of vehicles participating in Smog Check was also determined from the VID. We estimate that in 1999 Smog Check reduced tailpipe emissions of HC, CO, and NO(x) by 97, 1690, and 81 t/d, respectively. These correspond to 26, 34, and 14% of the HC, CO, and NO(x) that would have been emitted by vehicles in the absence of Smog Check. These estimates are highly sensitive to assumptions about vehicle deterioration in the absence of Smog Check. Considering the estimated uncertainty in these assumptions yields a range for calculated benefits: 46-128 t/d of HC, 860-2200 t/d of CO, and 60-91 t/d of NO(x). Repair of vehicles that failed an initial, official Smog Check appears to be the most important mechanism of emission reductions, but pre-inspection maintenance and repair also contributed substantially.

Giroux, Isabelle; Jacques, Christian; Ladouceur, Robert; Leclerc, Martin; Brochu, Priscilla

OBJECTIF : Estimer la prévalence des habitudes aux jeux de hasard et d'argent (JHA), du jeu à risque (JAR) et du jeu pathologique probable (JPP) dans la région de la Gaspésie et des Îles-de-la-Madeleine (GIM) (Québec). MÉTHODE : Un sondage téléphonique portant sur les habitudes de jeu a été réalisé auprès de 1014 adultes résidents de la région de la GIM. Les participants ont été sélectionnés aléatoirement. L'échelle Problem Gambling Severity Index de l'Indice canadien du jeu excessif a servi à l'évaluation du jeu pathologique. RÉSULTATS : Quatre-vingt-cinq pour cent des répondants rapportent avoir joué à un JHA au cours de l'année précédente. Les activités les plus populaires sont l'achat de billets de loterie, la participation à des tirages et collectes de fonds, le bingo, les cartes ou jeux de société en famille ou avec des amis pour de l'argent, la loterie vidéo et les jeux de casino. Les taux de prévalence du JAR et du JPP s'élèvent à 1,5 % et 0,8 % respectivement. La loterie vidéo s'avère le jeu le plus souvent identifié comme étant problématique, suivi des loteries instantanées et ordinaires (par exemple, Lotto 6/49). Les habitudes de jeu des Gaspésiens et des Madelinots sont similaires à celles observées chez l'ensemble des Québécois. La discussion soulève entre autres la question de la validité de l'évaluation de la présence d'un problème de jeu parmi les membres de l'entourage, et certaines perceptions à risque, dont celle qu'il est impossible de développer un problème aux loteries instantanées et au bingo.

Vad och hur gör de? − att synliggöra lärande i grundskolans slöjdpraktik via videoetnografi och mikroanalys

Full Text Available Artikeln bygger på resultat och erfarenheter av etnografiskt insamlade videoinspelningar från grundskolans slöjdundervisning utgående från tre studier; dels vid ett projekt med förstudier under slutet av 1990-talet (Johansson, 1996, dels vid avhandlingsprojektet Slöjdpraktik i skolan (Johansson, 2002 och dels inom forskningsprojektet Kommunikation och lärande i slöjdpraktiker, (”Komolär-projektet”, under 2005−2010 (Lindström, Borg, Johansson & Lindberg, 2003.Att insamla empiri i autentiska slöjdmiljöer är av intresse då lärandesituationer kan synliggöras när elever med hjälp av material och redskap arbetar med att tillverka artefakter. Utifrån detaljerade analyser av slöjdaktiviteter går det att upptäcka det som utspelar sig och möjligheter ges att uppfatta något annat jämfört med vad man kan tro känna väl eller ha förenklade och till och med felaktiga uppfattningar om. Videoobservationer möjliggör att antaganden istället görs på empiriskt grundat datamaterial. Med risk att videofilma och analysera det man tror sig veta och söka har forskningsprojektens insamlingar mer förutsättningslöst arbetat efter vad och hur elever och lärare gör i slöjdpraktik och vad man får veta när slöjdaktiviteter analyseras mer ingående. Videomaterialen har analyserats både på en mer övergripande nivå och detaljerat med hjälp av mikroanalyser. Därefter har lärandet synliggjorts och beskrivits bland annat i teman för att visa hur personerna är resurser för varandra och hur lärandet utvecklas genom olika språkanvändning och med slöjdpraktikens fysiska redskap och material.Sökord: metod, slöjd, klassrumsforskning, videoetnografi, mikroanalysURN:NBN:no-29955

Full Text Available El dossier central de este número de la Revista de Historia Social y de las Mentalidades se organiza en torno al tema de “Viñas, vino y sociedad en Chile Tradicional”. El cultivo de la vid aparece asociado muy tempranamente a las actividades agrícolas de Chile. Hasta el siglo XVIII, los viñedos locales satisfacían holgadamente el consumo doméstico, pero sin llegar a constituir una prometedora esperanza de desarrollo agrícola. El paso desde un cultivo arbustivo escasamente expansivo a una industria agraria moderna y consolidada se dio muy recientemente. De hecho, la presencia del vino chileno en los mercados internacionales, el auge de las exportaciones, el crecimiento de la superficie vitícola y la proliferación de empresas vinícolas solo se advierte en la segunda mitad del siglo XX.

Television food marketing to children revisited: the Federal Trade Commission has the constitutional and statutory authority to regulate.

Science.gov (United States)

Pomeranz, Jennifer L

2010-01-01

The evidence reveals that young children are targeted by food and beverage advertisers but are unable to comprehend the commercial context and persuasive intent of marketing. Although the First Amendment protects commercial speech, it does not protect deceptive and misleading speech for profit. Marketing directed at children may fall into this category of unprotected speech. Further, children do not have the same First Amendment right to receive speech as adults. For the first time since the Federal Trade Commission's original attempt to regulate marketing to children in the 1970s (termed KidVid), the political, scientific, and legal climate coalesce to make the time well-suited to reevaluate the FTC's authority for action. This paper analyzes the constitutional authority for the FTC to regulate television food marketing directed at children as deceptive in light of the most robust public health evidence on the subject.

“Yo soy el profesor”: Héroe mítico y nueva masculinidad en el manga Great Teacher Onizuka

2016-02-01

Full Text Available The objective of this work is the analysis of Japanese comics Great Teacher Onizuka, created by the artist Tōru Fujisawa and published in Mexico in 2006 by Editorial Vid. Through the analysis of image and text, we analyze the way in which the main character, Onizuka, is building like a hero according to the theory of heroic adventure, the mythological cycle and characteristics assigned Joseph Campbell to the mythical hero. On the other hand, we want to examine the way in which the protagonist transgress stereotypes of masculinity based on figures powerful physical appearance, which embody a set of moral values and, through different attributes and actions contribute to shaping the male identity linked to violence in the patriarchal system. We intend to visualize how the character of Onizuka although it plays a mythical hero, represents a break in the schemes of masculinity by showing an alternate model of “being a man”.

Measuring fish and their physical habitats: Versatile 2D and 3D video techniques with user-friendly software

Science.gov (United States)

Neuswanger, Jason R.; Wipfli, Mark S.; Rosenberger, Amanda E.; Hughes, Nicholas F.

2017-01-01

Applications of video in fisheries research range from simple biodiversity surveys to three-dimensional (3D) measurement of complex swimming, schooling, feeding, and territorial behaviors. However, researchers lack a transparently developed, easy-to-use, general purpose tool for 3D video measurement and event logging. Thus, we developed a new measurement system, with freely available, user-friendly software, easily obtained hardware, and flexible underlying mathematical methods capable of high precision and accuracy. The software, VidSync, allows users to efficiently record, organize, and navigate complex 2D or 3D measurements of fish and their physical habitats. Laboratory tests showed submillimetre accuracy in length measurements of 50.8 mm targets at close range, with increasing errors (mostly competitors, out to a distance of 1.0 to 2.9 body lengths. This system makes 3D video measurement a practical tool for laboratory and field studies of aquatic or terrestrial animal behavior and ecology.

Full Text Available The discourses of crisis in the humanities is juxtaposed with an analysis of remix video practices to suggest that the cognitive and cultural engagement feared lost in the former appear with frequency and enthusiasm in the latter. Whether humanists focus on the deleterious effects of the digital or celebrate the digital humanities but resist a turn to computation, their anxieties turn to the disappearance of textual analysis, aesthetics, critique, and self-reflection. Remix video, as exemplified by mashups, trailer remixes, and vids, depends on these same competencies for the creation and circulation of its works. Remix video is not the answer to the crises of the humanities; rather, the recognition of a common set of practices, skills, and values underpinning scholars and video practitioners' work provides the basis for a coalitional approach: identification of shared opportunities to promote and engage potential participants in the modes of thinking and production that contend with complex cultural ideas.

Reindeer pastoralism in Sweden 1550-1950

during hundreds of years. To a large extent these long-term external influences have made reindeer pastoralism what it is today. That aspect should not be overlooked when assessing the future prospects of reindeer pastoralism in Scandinavia.Renskötseln i Sverige 1550-1950Abstract in Swedish / Sammanfattning: Först vid mitten av 1500-talet finns det källmaterial som ger oss en tämligen detaljerad bild av renskötseln i Sverige. Vid den tiden levde samerna i en jakt- , fiske- och samlarekonomi. En familj hade normalt 10-20 renar som främst utnyttjades vid transporter. Tamrenarna kunde också mjölkas och fungera som lockdjur vid vildrensjakt. Under senare delen av 1500-talet köpte svenska staten och handelsmän stora mängder pälsverk av samerna. Den vanligaste betalningen var smör och mjöl. Detta skapade ett välstånd som ledde till en betydande folkökning i svenska lappmarken. Befolkningen blev för stor för att rymmas inom ramarna för en jaktochfiskeekonomi. En kris i början av 1600-talet blev startpunkten för övergången till en storskalig rennomadism.Fram till mitten av 1700-talet var den intensiva renskötseln framgångsrik. Men renskötseln blev efterhand alltför intensiv. Under senare delen av 1700-talet började det spridas sjukdomar i de tätt sammanhållna hjordarna. De första decennierna av 1800-talet innebar en allvarlig kris i renskötseln. Antalet renskötande fjällsamer minskade kraftigt, främst genom utvandring till norska kusten. Den intensiva renskötseln med mjölkning av renarna började ersättas av en extensiv renskötsel inriktad på köttproduktion de sista decennierna av 1800-talet. I norr var naturförhållandena och influenser från Kautokeino-samerna en viktig faktor, i söder utvecklades renskötseln i extensiv riktning främst därför att marknaden för renkött kom närmare renskötarna. Under 1920-talet upphörde mjölkningen av renar i Sverige, utom i några enstaka familjer. Då hade förflyttningarna av samer fr

The pellets consists of dewatered peat mixed with milled biomass into a workable compound. The compound is led to a storage tank through which hot air from a heat exchanger is blown. The pre-dried compound then passes a pellet press. The pellets are moved to a heat insulated dryer with a perforated bottom through which hot gas is blown and when the pellets have a sufficient percentage of moisture they are cooled by blowing cool gas through the drier, thus producing durable pellets.

Long term effects of ash fertilization of reed canary grass; Laangtidseffekter av askgoedsling vid roerflensodling

Energy Technology Data Exchange (ETDEWEB)

Palmborg, Cecilia; Lindvall, Eva

2011-03-15

Reed canary grass (RCG) is a bio-energy crop with large potential. It is a 1.5 . 2.5 m tall grass that is harvested in spring when it is grown as a fuel. At spring harvest it yields 3 . 10 ton field dried material per ha and year. One disadvantage when reed canary grass is used as a fuel is the high ash content, 5-10 %. This means that large quantities of ash have to be deposited which is expensive, about 1000 SEK/ton. However, since reed canary grass ash contains reasonable amounts of plant nutrients like phosphorous (P), potassium (K) and magnesium (Mg) it could be recycled as fertilizer in agriculture. The ash can be used without any pretreatment since, in agriculture, plant availability is desirable. The aim of this project, was to evaluate a field experiment, where ash was used as a fertilizer in reed canary grass. The experiment was established at the SLU research station in Umea, Sweden in the spring 2002. Three different fertilizer treatments were applied: Treatment A was fertilized with an ash produced by combustion of RCG together with municipal wastes (paper, plastic, leather), treatment B, an ash from combustion of RCG, and for treatment C commercial fertilizers were used. In total, 100 kg ha-1 of nitrogen (N), 15 kg ha-1 of phosphorous (P) and 80 kg ha-1 of potassium (K), were applied each year in all treatments. The amount of ash in treatment A and B was calculated from the chemical analysis of the ashes to be equal to the required amount of P, while K and N were supplied also by commercial fertilizers. [Table 1. Composition of the ashes] Literature study: There is a lack of knowledge about fertilization with reed canary grass ash, since few experiments have been conducted. The composition of reed canary grass is dependent of harvest date and the soil substrate. The amount of ash and the amount of harmful substances such as potassium and chloride generally decreases over winter, giving an increased fuel quality from spring harvest compared to autumn harvest. The main component of the ash is silica and silica concentrations are higher when reed canary grass is grown on clay soil than on peat soil. In an earlier project within the department of agricultural research for northern Sweden, SLU Umea, reed canary grass growing on peat soil was fertilized with ash from cocombustion of reed canary grass and sorted municipal waste. This ash was beneficial for the growth of the grass and did not give increased heavy metal contents. However the experiment only lasted two years so no conclusions could be drawn about long-term effects. Crop yields and elemental composition of the crop: The yields varied very much from year to year. The first two production years, 2004 and 2005 the yield was at expected levels, 6000-7000 kg dry matter per ha and year. After that, 2006-2009 the yields have been lower than expected, 1500 - 4000 kg dry matter per ha and year. The reason for this is not known, but it could be related to climate or pests. There were no significant differences in yield between the treatments. Samples from each plot from the last harvest and stored samples from 2004 were analyzed for nutrient and heavy metal content. There were only minor significant differences between the treatments: The ash and the potassium and calcium concentrations 2009 in grass from treatment A, ash from co-combustion of reed canary grass and waste, was slightly higher than in the NPK fertilized control. The magnesium concentration in 2009 was slightly higher in grass fertilized with reed canary grass ash than in the control grass. Element balances and soil concentrations of elements: Because of the low yield levels the amounts of P and K applied were much higher than the removal with harvests (Table 2). This resulted in an increase in plant available P and K in the top soil between 2003 and 2008 (Table 3). However, in the subsoil there was a decrease especially in plant available P. The only significant differences in soil nutrients between the treatments 2008 were for Ca, where treatment A had higher concentrations and Mg where treatment A and B had higher concentrations than the control. Only treatment A had an increased pH compared to the control. This is probably because reed canary grass ash is rich in silica oxide which is acidic. [Table 2. Balance between supplied and removed amounts of nutritional elements and heavy metals during the experimental period. The removed amount per hectare has been calculated from the average between analyzes from 2004 and 2009, and dry matter yield per year. The only heavy metal content available for the fertilizers was Cd content in the phosphate.] [Table 3. pH-value and content of plant nutrients 2003 (per treatment) and 2008 (per plot) in topsoil and subsoil. Analysis of plant available nutrients by extraction with ammonium lactate.] In treatment A, the amounts of heavy metals applied greatly exceeded the limits for sewage sludge set by Swedish Environmental Protection Agency.

Thus, a business model was established and stabilized in the 1980s along screening windows. The digital revolution broke this business model in France as well as in the United States. However, while in France, the film investment schemes and Canal Plus Group’s established position as a major source of finance led to the shortening of release windows but not to the disappearance of the release windows format, in the United States, the declining DVD sales and revenues forced the major studios to study new methods of distribution and new business models, based on day-and-date releases and on the gradual dissolution of the windows model.

The study deals with emissions of toxic compounds from waste treatment to the environment with the aim of improving the state of knowledge and to find a way of describing the environmental impact from these substances. Toxicity is one of a number of environmental aspects necessary to address in the planning of waste treatment and in the daily waste treatment routines in order to fulfill the environmental objective A Non-Toxic Environment and other environmental requirements. The study includes waste to incineration, composting and anaerobic digestion. A comparison between methods were made for biological household waste. According to our study, the compounds of importance for waste treatment are metals and persistent organic compounds. These tend to bioaccumulate and enrich in food chains. The substances are important for the environmental objective A Non-Toxic Environment. In a first step the compounds chosen in this study may be suggested for describing toxicity from waste treatment: As, Cd, Cu, Hg, Pb, dioxin, PCB, the phthalate DEHP and the brominated flame retardant HBCDD. Other substances may be added to the list in a next step from up-dated and quality-assured characterisation factors or from other requirements or preferences. There is a limited knowledge on toxic compounds in waste flows and in different environmental compartments. More data are available for metals than for organic substances. There is also a limited knowledge on the fate of the compounds during the waste treatment processes. Most information is found for incineration. During composting and anaerobic digestion the metals will mainly be emitted to the environment by use of the compost and the anaerobic digestion residue. Organic substances will to some extent be degraded during the processes. However, there are gaps of knowledge to fill for the further work on estimating toxic emissions. There is mainly a need for more extensive data on toxic compounds in waste and their variations. A test was made to use a weighted index for toxicity - such as used for climate impact, acidification, etc. in system analyses for waste treatment. The result was not useful due to the limited availability of characterisation factors for the chosen substances. In stead, the toxic impact was assessed by other comparisons, from a local and a national perspective. No acute effects on human health and on the environment are expected to occur from waste processes or from the use of compost and anaerobic digestion residue. The conclusion is that emissions of toxic substances from waste treatment will contribute to the present fugitive levels of pollutants in the environment. The toxic impact is proposed to be quantified as the total emission of metals and persistent organic pollutants, without consideration to the way emissions are made; to air, water and soil. Emissions, even though they are small, contribute to present levels of pollution with the risk of further elevated concentrations and further dispersion in nutrient chains. In all environ metal work it is essential to reduce emissions of toxic persistent compounds. Many activities in society contribute to the total levels. Waste treatment is an unavoidable activity in the society. By massive actions to limit the use and to con tol the emissions of toxic compounds, a cleaner waste is expected to be the result. In addition, measures such as more effective source separation and separation of hazardous waste will make a more optimised treatment of different types of waste possible

The results from this project show that phosphorous-rich additives could be of interest to reduce fouling and high temperature corrosion without causing increase in slagging and/or bed agglomeration tendency for typical biofuels. General results in this series of experiments show that in order to achieve a good potassium-binding effect the calcium and magnesium content should be low in the phosphorous-rich fuel and additive. If the content of Ca and Mg is high in the final fuel mixture (including both P-fuel/additive and the bulk fuel) the K-binding effect is reduced and more P needs to be added. Of course, this also means that the additive of choice (fuel or chemical) should have a low content of calcium and magnesium. It is therefore probable that the best results will be obtained when using a fuel mix where the final blend has a molar ratio of P/(K+Na+2/3Ca+2/3Mg) approaching 1. For instance, using monoammonium phosphate, this would be equivalent to a cost (autumn 2009) of about 9-14, 10-15 and 30-40 SEK in P-additive cost per MWh of added fuel to achieve this molar ratio for typical logging residue, salix and wheat straw biofuels.

Corrosion risks with polyethylene pipes in district cooling systems; Korrosionsrisker vid anvaendning av polyetenroer i fjaerrkylesystem

Field exposures of carbon steel and stainless steel test cylinders have been made in the district cooling system at Affaersverken Energi AB, Karlskrona, Sweden, as well as determinations of the amount of dissolved oxygen in the district cooling water. In the district cooling system tubes of polyethylene, carbon steel and stainless steel SS 2343 according to Swedish standard SS 14 23 43 are used. Karlskrona's drinking water, without deaeration, is used in the district cooling system. The polyethylene tubes with pressure number PN 10 are placed underground. The content of dissolved oxygen was very low in Karlskrona both before and after a period of 19 days with elevated oxygen content. During these 19 days the content of dissolved oxygen in the system increased without any apparent cause. The highest recorded oxygen content was 3.4 mg O{sub 2}/l. There are no obvious explanations for the increase of oxygen in the system. However, transport of oxygen into the system through the polyethylene tubes can be excluded as the source of the entering oxygen. The corrosion rate that was determined for freely exposed carbon steel in the district heating water in Karlskrona was low, 5 {mu}m/year. The corrosion attack was of a uniform nature (general corrosion) and there were no local corrosion attacks on the carbon steel cylinders. On connecting the carbon steel with stainless steel SS 23 43 with an area ratio of 1:1 the corrosion rate of the carbon steel increased by 2-3 times as compared to free exposure without electrical connection. On the stainless steel SS 2343 there was no corrosion damage either on the freely exposed stainless steel or on stainless steel that was connected to carbon steel. There were no signs of pitting corrosion or crevice corrosion on the stainless steel cylinders. The main corrosion risk for carbon steel at an elevated content of dissolved oxygen is bimetallic corrosion (galvanic corrosion) between carbon steel and copper and copper alloys, or between carbon steel and stainless steel. Calculations show that the amount of oxygen gas that is transported through the walls of polyethylene tubes in air is very small. This amount of oxygen causes a slow corrosion on carbon steel. For polyethylene tubes in soil the oxygen transport through the tubes will be considerably lower than for tubes in air. Recommendations state that the area of carbon steel should be at least 10 % of the area of the polythene tubes if the polyethylene tubes are placed outdoors or indoors in air and not in soil. The reason is that the carbon steel tubes should use up the oxygen that is transported through the tubes. The most important reason for reducing the oxygen content in the system is the risk of bimetallic corrosion on the carbon steel. Another purpose for recommending a certain minimum area of carbon steel in the system is that any oxygen from unforeseen air intakes, from system starts and major additions of makeup water to the system with un-degassed water should be consumed, without causing significant corrosion on the carbon steel. For district cooling systems with polyethylene tubes placed in soil it is recommended that the area of carbon steel should be at least 5 % of the polyethylene tube area, to take care of unintentional intakes of air and system starts and major toppings with un-degassed water. It is recommended that the risks of accidental intakes of oxygen into the district cooling system should be considered. With the present use of soil-placed polyethylene tubes in district cooling systems the risks connected with accidental oxygen intakes are judged to be greater than the risk of oxygen diffusion through the polyethylene tubes. Furthermore, it is recommended that the risks of bimetallic corrosion should be taken in account at the design of district heating systems. The current use of soil-placed polyethylene tubes in district cooling systems with large quantities of carbon steel in the system is not considered to cause any risk of corrosion. The amount of oxygen that is transported through the polyethylene tubes is very small.

Deep Spatial-Temporal Joint Feature Representation for Video Object Detection.

2018-03-04

With the development of deep neural networks, many object detection frameworks have shown great success in the fields of smart surveillance, self-driving cars, and facial recognition. However, the data sources are usually videos, and the object detection frameworks are mostly established on still images and only use the spatial information, which means that the feature consistency cannot be ensured because the training procedure loses temporal information. To address these problems, we propose a single, fully-convolutional neural network-based object detection framework that involves temporal information by using Siamese networks. In the training procedure, first, the prediction network combines the multiscale feature map to handle objects of various sizes. Second, we introduce a correlation loss by using the Siamese network, which provides neighboring frame features. This correlation loss represents object co-occurrences across time to aid the consistent feature generation. Since the correlation loss should use the information of the track ID and detection label, our video object detection network has been evaluated on the large-scale ImageNet VID dataset where it achieves a 69.5% mean average precision (mAP).

Full Text Available From the eighteenth century until today Cuyo and central Chile have been the main viticulture centers in Latin America and one of the most developed in the world. Their wine and spirits making have had important social, economic, politic and cultural implications in the region. Behind this, there has been viticulture, intensive and specialized farm-working, and viticulturists, who have had key roles. This article, based on originals and unpublished documents from Santiago, Mendoza, and San Juan notaries and court archives, examines varieties cultivated in the region. At the end, a document corpus was generated with 3.5 million plants in order to identify time of entry, adaptation, and propagation of grape varieties from Spanish colonization until French strains entered the region during mid nineteenth century. In particular, coexistence of Pais grape and Italia grape (muscat of Alexandria is examined, which had direct influence over the appearance of the Torrontes variety. The latest is the only high value wine-making Creole variety that prevails until today and is the most important in white-wine-making in Argentina.Cuyo y Chile central constituyen, desde el siglo XVIII hasta hoy, el principal polo vitivinícola de América Latina y uno de los con mayor desarrollo del mundo.

Full Text Available Botrytis cinerea Pers., the causal agent of gray mold, infects more than 200 plant species. This pathogen has traditionally been controlled by fungicides. However, with the increasing demand for pesticide-free foods new control strategies are needed. The objective of this study was to isolate and select grapevine (Vitis vinifera L. epiphytic yeasts for the biocontrol of B. cinerea in table grapes. Of the total isolated yeasts (n = 256, 32 exhibited mycelial growth inhibition in dual cultures with a halo > 4 mm, and eight of these isolates inhibited > 90% of conidial germination. When evaluating increasing concentrations on conidial germination inhibition, a dose-dependent response was observed with EC90 values from 0.45 x 10(5 to 0.22 x 10(8 cells mL-1. The antagonistic activity of six yeasts against B. cinerea in table grape berries 'Flame Seedless' increased as the yeast colonization time increased from 1 to 24 h on the berries, resulting in a higher biocontrol activity on B. cinerea. These results show the effectiveness of grapevine epiphytic yeasts as biocontrol agents of B. cinerea on table grapes.Botrytis cinerea Pers., agente causal de la pudrición gris, infecta a más de 200 especies vegetales.

As a consequence of the growing impact on water resources the Water Framework Directive was legislated in 2000. The directive should ensure that a 'good water status' and entail a coordinated legislation striving for a long-term protection of all water resources. Stakeholders should be able to participate in the preparations of river basin management plans and programs of measures. District based water authorities will administrate the implementation and are mandated to decide upon regional environmental quality standards and promulgate fees for water use and discharges. The Directive contains a list of 33 prioritized substances that should be reduced or phased out. Discharges from combustion plants contain twelve, polyaromatic hydrocarbons (PAH) and heavy metals. PAH and heavy metals impacts growth and vital functions as respiration and photosynthesis of water living organisms and induces cancer in humans. NOEC-values (NO Effect Concentration) state manageable substance concentrations for an organism. Flue gas condensate contains concentrations of some of the substances which impact exceeds the critical state level. Extended sewage treatment could thus be needed. Sludge, wash and soot water contains elevated levels of heavy metals. This water is normally treated by municipal sewage treatment. Further treatment at plant site could be relevant. Presence of PAH and heavy metals in leach water depends on the precipitation. Additional flowing-independent water treatment could be relevant. It is very uncertain how plant owners will be affected. Licenses could be reviewed and standards could be raised for sensitive recipients; new limits for prioritized substances and standards for other types of discharges and water fees could be added. Respites could be given if costs exceed the benefits. Location, ecotoxicological risk assessments and precautionary measures could become more relevant in an EIA. Pricing of water could take place by using a system of emissions trading. Plant owners could make an impact by participating in development of environmental quality standards plans and programs by representation in public consultations and cooperative groups. Methods for improvement to meet the new standards are presented in the categories fuel, combustion, flue gas- and flue gas condensate treatment. The prioritized substances shouldn't be introduced or generated in the system to avoid costly investments of advanced technologies. Heavy metals are reduced by the choice of fuel and complete combustion generates less PAH. Both of the substances could be reduced by the separation of particles. An example of an appropriateness assessment according to a model considering the overall plant conditions including technological, economic and organizational aspects is demonstrated. For a 'standard plant' the best choice of fuel would be wood chips combined with stable combustion. Given the prerequisites of the model, the most appropriate flue gas treatment were a bag filter without chemical dosing and the most appropriate flue gas condensate-, slug-, wash-, and soot water treatment would be sand- or lamella filter with pH-adjustment, together with leach water treatment by sedimentation and sand filter. If another type of plant would be considered, other methods would be more optimal Hence, the model should be used in a 'plant specific' manner and then be a useful tool in negotiations with authorities if/when measures will be taken to reach the standards of the Water Framework Directive.

Emissions of volatile hydrocarbons (VOC) during drying of sawdust; Utslaepp av laettflyktiga kolvaeten vid torkning av biobraenslen

Granstroem, Karin

2001-08-01

In the project 'Emissions of volatile hydrocarbons (VOC) during drying of sawdust' the identity, amount and composition of monoterpenes found in the drying medium of a fluidized bed drier drying sawdust from Norwegian spruce and Scotch pine has been determined. The energy efficiency of the drier has also been measured. The aim of this project was to reduce both emissions and energy required for drying, to minimize environmental and health hazards, and make drying more competitive. This would help our primary target group - small scale saw mills - to make use of the sawdust produced as a by- product by making pellets and briquettes. If the VOC remains in the sawdust its energy content will improve and therefore also its value as a fuel. The sawdust was dried to different moisture levels in a spouted bed drier at atmospheric pressure, using either recirculating or not recirculating drying medium with temperatures 140, 170 or 200 deg C. The emissions of VOC were measured using a flame ionization detector (FID) and the nature of the emissions analyzed with a gas chromatograph with mass spectrometric detector (GC-MS). The GC-MS data is reported as emitted substance per oven dry weight (odw). Experiments show that terpenes do not leave the sawdust in great amounts until it is dried to a moisture content (water/total weight) below 10%. When sawdust is dried to a predetermined moisture level, the terpene emissions increase when warmer incoming drying medium is used. The monoterpenes found in greatest amount are a-pinene, b-pinene, 3-carene, limonene and myrcene. y-terpinene was detected in emissions from pine but not from spruce. The relative amounts of different monoterpenes did not vary significantly with post-drying moisture content, but drying medium of higher temperature caused an increase in the relative amount of less volatile monoterpenes. The FID data is reported as concentration of VOC in the drying medium, and as weight VOC per odw. The concentration of VOC increases when the temperature of the gas that enters the drying tower is increased. A mass balance shows that the concentration VOC is proportional to emitted VOC per odw. The concentration VOC is fairly constant at different moisture contents of outgoing sawdust when the drying medium is recirculated, but VOC per odw shows an increase in emissions at lower sawdust moisture contents. The energy efficiency was highest for the tests with high temperature of incoming drying medium. As the sawdust was dried to less moisture content the energy efficiency dropped regardless of the temperature of incoming drying medium. When the drying medium was not recirculated the energy efficiency was poor. An important conclusion is that driers with a spouted bed should use recirculating drying medium, since it is clearly superior to not recirculating drying medium. Another important conclusion is that to minimize emissions from the drier the temperature of incoming drying medium should be kept low and the moisture content of the sawdust above 10%.

Fouling and slagging problems at recovered wood fuel combustion; Orsaker till askrelaterade driftproblem vid eldning av returtraeflis

CHP-plants that use a large portion of sorted wood waste fuel can face ash-related problems. By analysing the circumstances about these problems, the goal is to find causes for the problems and measures that can be taken. This knowledge can then be utilised in plants where it is desired to increase the portion of sorted wood waste fuel. For the measurements, a deposit probe is a good tool to use since the result is independent of many boiler-specific factors. Compared with forest residues, sorted wood waste causes a more problematic ash. The risk of troublesome fouling and corrosion seems to increase with increased admixture of sorted wood waste fuel. Plugging of the grate is associated with melts that are formed from metallic contamination in the fuel. These melts obstruct the air holes. The melts that have been seen during the project have had a content of aluminium, brass and zinc. In order to solve these problems, the construction and cooling of the grate and quality assurance of the fuel are important aspects. One problem that was found in all of the studied boilers (grates as well as fluidized beds) is growth of fouling on surfaces for heat transfer. Measurements with deposit probe show that the initial growth rate on superheaters are approximately 3 - 5 times higher when sorted wood waste is used than if forest residues is used. Even if this growth rate can not be extrapolated to a complete operating season, the relative difference between the fuels remains. The extent of the problem depends on the dimensioning of the boiler. The fouling tends to have a light outer layer that can be disadvantageous for the absorption of heat radiation. Haendeloe P11 needs for example to be stopped for cleaning with an interval of 2 - 3 months because of lost heat absorption in the furnace and the convection path. The most obvious ash related problem that was found in Haendeloe P11 when 100 % sorted wood waste fuel was used was corrosion on the walls of the lower parts of the furnace. The corrosion has forced an exchange of large parts of the panel walls. More or less severe corrosion on the superheaters is reported from all of the boilers that were studied in the project. Since most of them use sorted wood waste mixed with some other fuel, it is difficult to make conclusions about the specific role of the sorted wood waste fuel for this corrosion. Long-term measurements with a deposit probe in Haendeloe P11 shows that the deposit growth rate varies with a factor five from day to day, although the load is relatively constant. In addition to the typical components in wood fuel ash such as calcium, potassium and sulphur, also zinc, lead, and in some cases titanium are concentrated in the deposits. Zinc is common in the deposits from the grate furnaces and the CFB within the concentration interval 5 - 20 % (also higher contents occur). The zinc content was lower in the deposits from the CFB. Lead and titanium was found to a higher extent in the fluidized bed boilers.

Why and how to make a REACH registration of combustion ash; Moejligheter vid REACH-registrering av energiaskor

Energy Technology Data Exchange (ETDEWEB)

Loevgren, Linnea; Wik, Ola

2009-10-15

The new chemical regulation, REACH (1997/2006/EC), Registration, Evaluation, Authorization and restriction of Chemicals, took effect the 1st of June 2007. The background to this report was the introduction of REACH and the difficulties to understand the implications for ash. The most important consequence of REACH is that all chemical substances that are manufactured, handled and used above one tonne per annum per legal entity shall be registered according to this regulation. The registration includes specifying the chemical, physical, toxicity and ecotoxicity properties of the substance and risk assessing the identified areas of use. The report describes the use of ash in connection to the waste legislation and its planned end-of-waste-criteria, the chemical legislation and the Construction Products Directive. The target audience of this report is companies producing ashes and having a use or seeing a use for its ash. The report describes how to make a REACH registration of ash independent if a company did or did not pre-register ash during 2008. It describes how to change from one ash registration into another if the pre-registration was done for one type of ash but the company changes opinion during the sameness check, i.e. changing SIEF (Appendix A). Taking part in REACH registration projects during 2009-2010 can be advantageous since knowledge and financing are shared. Ash can be REACH registered also in the future but it is important to know that the registration have to be done prior the production and marketing starts. If ash is consider to be a waste the handling is covered by the community and national waste legislation. In Sweden ashes are by and large being regarded as waste, and recycling is risk assessed and permits are given case by case. End-of-waste criteria for different waste material are being elaborated within the EU. Such criteria will among other details cover chemical safety. When a material fulfils the end-of-waste criteria such material will have the possibility to leave the waste legislation and be covered by the chemical legislation in becoming a product or an article. It is not know in detail how far the chemical legislation will reach for material having end-of-waste criteria. Currently, end-of-waste criteria have not yet been initiated for ashes. The Swedish Environmental Protection Agency (Naturvaardsverket) is currently elaborating end-of-waste criteria for the use of material in construction works. Recovering waste is according to REACH identical with manufacturing. A chemical substance, preparation/mixture or article manufactured from waste, i.e. via a recovering operation will have to follow chemical legislation. The enterprise responsible for the recovering operation is the legal entity responsible to follow REACH for the manufactured material. One example of recovering ash into a chemical substance is the manufacturing of cement when ash is the raw material. It is the responsibility of the cement plant to have its substance or product REACH-registered before manufactured and provided to a third party. The waste legislation, instead of the chemical legislation, applies when the waste recovering operation does not results in manufacturing of a substance, preparation or article provided to a third party and the waste has a use at the end of its life cycle. This is identified as late recovery. The waste legislation applies during the life cycle of the waste in such cases. Examples in Sweden are ashes used in landfill sealing and covering layers and in roads or soil stabilization. Use of ashes in constructions is covered by the Constructions Product Directive (2008/98/EC), CPD, irrespective if it is identified as a waste or a chemical product. The CPD harmonizes only testing and CE-marking of construction products. Chemical safety requirements originate from national legislation which in many cases is based on chemical regulation. Standardized testing methods to measure emitted hazardous substances from construction products were initiated in 2006 on the EU level. The proposed method s are similar to leaching methods used today in characterization of waste properties for landfill. The report describes pros and cons with REACH registration of ashes. It is believed that uses of ashes will more easily be available if the ashes are registered according to REACH. The reason is that a REACH registration generates extensive information about properties and emissions during uses and that safety instructions will be available to guarantee that emissions will not be higher than what man and nature can sustain. The fee for a joint submission of a REACH registration is 23,250 Euro per legal entity if the company put more than 1,000 tonnes of the dry substance on the market per year.

Bag filters at biofuelled plants, reliability and economy of operation; Slangfilter vid bioeldade anlaeggningar, tillfoerlitlighet och driftsekonomi

The background to this work is the increased requirements on dust emission control for smaller (2-50 MW) biofuel plants in Sweden, where established technology consisting of multi cyclones cannot meet the emission demands, and where the specific cost of the large scale established technology (electrostatic precipitators) quickly increases with decreased plant size. Operational experience of bag filters on Swedish biofuel plants down to a size of 2 MW has been collected. The operational experience is remarkably uniform and positive and availability is high. Bag life, being the most important operational cost factor, is between two and eleven years. Most frequent material used is aramide, but also PPS is employed and the experience of both materials is good. The cost relation between bag filter (including an upstream skimmer) and electrostatic precipitator has been studied based on supplier quotations. Bag filter always has the lowest first cost. At one year bag life, the total cost of a bag filter is less than that for an electrostatic precipitator for plants smaller than 15 MW, and at more than one year's bag life, the bag filter has the lowest total cost for plants up to 50 MW. For plants smaller than 5-10 MW, the difference in total cost is very high. With some simple means for quality assurance of new bags, premature failure rate can be reduced. Following up cleaning interval and/or emission during operation time, gives information about the development of bag condition and necessary bag change can be foreseen. Since bag filters are more prone to damage by fire than electrostatic precipitators, the process of damage due to entrained sparks has been analysed based on practical observations and a thermal calculation. This consideration shows that this damage mode can be eliminated by an upstream skimmer having moderate but reliable performance. The result is well in coherence with the practical operational experience found that with an adequate skimmer upstream, the failure becomes much less probable.

The alleged inter-relationship between economy and nuclear safety has been investigated. Through interviews and review of instructions and other documents, information on how management at Swedish nuclear power plants integrates financial control and safety management has been compiled. Owners of nuclear power plants have well founded expectations on that the plants are profitable and that the operations are rationalized in order to reduce costs. This could allegedly threaten the nuclear safety. However, it is not to be expected that there are any obvious relationships between expenditures and safety. The quality of the safety management has to be judged in terms of how well safety requirements are met irrespective of the associated costs. The owners have imposed clear financial objectives on the nuclear power plants. At the same time they have also established policies for nuclear safety. The nuclear power plants have systems for operations management, which basically comprise separate parts for operations planning and quality management. Financial control and safety management are included in the operations planning and quality management respectively. The quality management impose restrictions to be adhered to in the operations planning. This means that from a formal point of view, the safety management is superior to the operations planning. There are examples of simple as well as advanced approaches to financial management at the nuclear power plants. In all cases the methods used are reasonably well adapted to the needs. Typical for all plants is the focus on long-term aspects. Investments are for example analysed in a plant life-time perspective. With regard to safety, profitability calculations are not required to the same extent for safety related investments as for other investments. A number of factors, which tend to warrant that safety aspects are given the appropriate attention in the decision making, have been identified. Examples of such factors are the involvement of cross functional teams and external parties in the decision process, detailed and unambiguous instructions in the quality system and follow-up by organizational entities, which are independent of the line organization. In 2003 concerns related to the prioritization of financial control at the expense of safety were expressed at one nuclear power plant and management took action on this. There now appears to be a unanimous opinion at all Swedish nuclear power plants that safety really has a higher priority than financial control and that this is well reflected in company policies and in the systems for operations management. Above reference has only been made to the formal operations management. A common remark has been that the adherence to the quality system depends on the safety culture. In order to safeguard that the safety culture remains unaffected by any changes related the norms and values concerning economy, the safety culture should to a large extent be based on safety related institutional activities. Authority review of the financial control at the nuclear power plants should focus on that the quality system really is superior to the operations management. In addition, when reviewing the safety culture, the existence of stabilizing institutional safety related activities should be checked.

Deep Spatial-Temporal Joint Feature Representation for Video Object Detection

Directory of Open Access Journals (Sweden)

Baojun Zhao

2018-03-01

Full Text Available With the development of deep neural networks, many object detection frameworks have shown great success in the fields of smart surveillance, self-driving cars, and facial recognition. However, the data sources are usually videos, and the object detection frameworks are mostly established on still images and only use the spatial information, which means that the feature consistency cannot be ensured because the training procedure loses temporal information. To address these problems, we propose a single, fully-convolutional neural network-based object detection framework that involves temporal information by using Siamese networks. In the training procedure, first, the prediction network combines the multiscale feature map to handle objects of various sizes. Second, we introduce a correlation loss by using the Siamese network, which provides neighboring frame features. This correlation loss represents object co-occurrences across time to aid the consistent feature generation. Since the correlation loss should use the information of the track ID and detection label, our video object detection network has been evaluated on the large-scale ImageNet VID dataset where it achieves a 69.5% mean average precision (mAP.

Measuring fish and their physical habitats: Versatile 2D and 3D video techniques with user-friendly software

Science.gov (United States)

Neuswanger, Jason R.; Wipfli, Mark S.; Rosenberger, Amanda E.; Hughes, Nicholas F.

2017-01-01

Applications of video in fisheries research range from simple biodiversity surveys to three-dimensional (3D) measurement of complex swimming, schooling, feeding, and territorial behaviors. However, researchers lack a transparently developed, easy-to-use, general purpose tool for 3D video measurement and event logging. Thus, we developed a new measurement system, with freely available, user-friendly software, easily obtained hardware, and flexible underlying mathematical methods capable of high precision and accuracy. The software, VidSync, allows users to efficiently record, organize, and navigate complex 2D or 3D measurements of fish and their physical habitats. Laboratory tests showed submillimetre accuracy in length measurements of 50.8 mm targets at close range, with increasing errors (mostly <1%) at longer range and for longer targets. A field test on juvenile Chinook salmon (Oncorhynchus tshawytscha) feeding behavior in Alaska streams found that individuals within aggregations avoided the immediate proximity of their competitors, out to a distance of 1.0 to 2.9 body lengths. This system makes 3D video measurement a practical tool for laboratory and field studies of aquatic or terrestrial animal behavior and ecology.

Reduced bed temperature at thermo-chemical conversion of difficult fuels; Saenkt baeddtemperatur vid termokemisk omvandling av svaara braenslen

This work investigates the prospect of reducing the concentrations of alkali chlorides in the flue gas by lowering the temperature in the bottom zone of a fluidized bed (FB) furnace below the often used 850 deg C. The directive of a retention time of at least two seconds above 850 deg C is fulfilled by the raise of the flue gas temperature that follows the combustion of unburned gases at the point of injection of secondary and tertiary air, above the bottom bed zone. The aim of the present experiments is to determine the dependency between the temperature and the amount of alkali metals leaving the bottom bed for some selected waste and biomass fuels. The results are intended for plant owners as well as boiler manufacturers. The experiments were performed in an FB-reactor, which was externally heated to specific temperatures between 550 and 850 deg C. The reactor is made of a quartz glass tube with an inner diameter of 60 mm and a length of 1.2 m. The fluidized bed rests upon a porous plate of sintered quartz. The bed material used was 180 gram purified sea sand with particle sizes between 0.1 and 0.3 mm. The fluidizing gas was a mixture of nitrogen and air, introduced in the bottom of the reactor by mass flow controllers. At the outlet of the reactor, the flue gas was divided between conventional gas analyzers and an ICP-MS instrument. The gas flow to the ICP-MS instrument was cooled before a slip stream was sucked out via a capillary to a nebulizer from which the sample gas was led to the ICP-MS instrument. The function of the nebulizer is normally to form an aerosol of liquids, but here it was used solely as a pump. In addition, a known flow of krypton was added into the nebulizer to be used as an internal standard. The novel technique to measure the amount of alkali metals on-line from a batch fired FB-reactor has been shown to work in practice and to provide interesting results, which so far is qualitative only. Further development and calibration work is needed to obtain reliable quantitative results. Under pyrolysis (in nitrogen), a strong coupling was found between temperature and measured concentrations of alkali and zinc in the flue gas, especially between 750 and 850 deg C. These findings imply that reactors for gasification (or pyrolysis) of waste and biofuels will benefit from being operated at temperatures below 850 deg C to reduce the alkali content in the product gas. On the other hand, there could be other advantages of operating a gasifier at higher temperatures. The influence of the reactor temperature on the release of alkali metals was found to be less pronounced during combustion as compared to pyrolysis. The reason for this could be that oxygen takes part in the reaction scheme controlling the release of the alkali metals, but it could also be a consequence of locally higher temperatures in the fuel particle while burning. The tests showed that a larger fraction of zinc was released during devolatilisation, compared to the alkali metals of which typically less than 10 % was found to be released during devolatilisation. Some additional tests where HCl was added to the fluidizing gas showed, as expected, that the presence of HCl increases the release of alkali metals from the bottom ash. Agglomeration temperatures were determined for two bed sand samples that had been extracted under operating bed temperatures of 870 and 750 deg C in a commercial waste fired FB-boiler. While sand samples were heated in order to find the agglomeration temperature, considerably more alkali metals were released from the sand sampled at 750 deg C. The agglomeration temperature was somewhat lower for this sand, but it was still considerably higher than normal operating bed temperature of the boiler. The present lab-scale study shows that the release of alkali metals and zinc into the flue gas from waste is reduced, or at least considerably decelerated, by a lowered fuel conversion temperature. However, the atmosphere and bed material of a full scale waste fired power plant cannot be fully reproduced in lab scale. The differences will affect the release of alkali metals. Nevertheless, present study gives an indication that a reduced temperature of the bed may be beneficial. The experiments also showed that reducing atmosphere in the bed preferably should be avoided, at least at a bed temperature of 850 deg C

The aim of the experiment was to construct a tight, highly insulated, low energy and light intensive greenhouse in which demanding cultures could be cultivated troughout the year. Furthermore the house should have an open floorspace without blocking or shading structures, and be equipped with an airflow and ventilation system which makes airing unnecessary during the cold season. A day to night energy storage system should replace conventional heating. The house is erected on a concrete strip foundation in which heating coils are located. Furthermore, on the top of the cantilever are two layers of transparent plastic foil. Between the layers, removable insulating porous polystyrene balls will be filled or removed as outdoor temperature and light vary. The climate air passes the evaporators of three heat pumps and is then blown through an air/water heat exchanger and an electric radiator. The heat exchanger is supplied with hot water from a water tank heated by the heat pumps. When needed the air will be reheated in the heat exchanger and radiator. The heat evolved when the air is in the heat pump evaporators is stored in the water tank, in a salt storage and in the concrete floor with its heating coils. At night when outdoor temperature is low heat is transferred from the heat storage to the greenhouse. When inside temperature or humidity becomes too high, outdoor air is added. From the two experimental periods 1982-1984 it is concluded that after certain modifications of the equipment it would be possible to grow Swedish garden produce all the year round without excessive heating costs.

Attitudes and participation at establishment of wind power offshore; Attityder och delaktighet vid etablering av vindkraft till havs

Wind power has previously been regarded as small-scale in character, as it has often been built as small groups of windmills. In recent years, wind power projects on a larger scale have been developed and established, making wind power more significant for the local community and its inhabitants. The present report is based on a study of views expressed by locals as regards offshore wind power. The report aims at examining the coordination between different stakeholders; decision-makers, communities and entrepreneurs concerning two wind power projects: Lillgrund in The Sound (Oeresund), and Utgrunden II in the Kalmar Strait (Kalmarsund). The report is intended to provide an understanding of attitudes and perceptions of risks and possibilities of various local stakeholders in these two cases. Conceptual tools are borrowed from our own studies as well as other researchers' previous studies of attitudes, values, and forms of public participation. Since the study objective has been to seek the stakeholders' own formulations of problems and opportunities concerning the projects, we have used a qualitative research design. Three types of techniques have been used to gather information: document analysis, field observations and in-depth interviews. Positive as well as negative attitudes towards the two wind power projects have been analyzed in both regions. The positive attitude is mainly based on ethical values, and for some also on material values (projects can create jobs and economic growth in the local community). The negative attitude is partly based on aesthetic values and a combination of substantive and ethical values (wind power is seen as unprofitable and inefficient). The analysis shows that there is need for increased knowledge, both through the provision of facts about economic and technical conditions of wind power and, by better understanding of local stakeholders' conceptions of wind power projects. Criticism of wind power is largely based on a view that it could not be an effective way to produce energy, and that it could not possibly bear its own costs. Thus, wind power entrepreneurs should clearly show environmental benefits, profitability and efficiency in a specific project draft. Moreover, negative emotions towards wind power projects are closely associated with aesthetic values. How people perceive the relative weight between opportunities and risks of the wind power establishment should be taken as a central part of the dialogue related to wind energy projects. It is crucial that the risks experienced by various stakeholders are identified and get substantial room in the planning and decision-making process, even if the entrepreneurs or authorities do not share these risk perceptions. In the local context, views of opportunities may function as a counter-weight to the negative effects that may be associated with the wind power project. It is highly preferable that these opportunities be identified in dialogue with the local community, and elucidated by the entrepreneurs and authorities. In this study, as well as in previous studies, it has been evident that limited potential for the local society to participate in the planning and decision process often overshadows the final result, in this case the physical wind power plant. The two projects studied were based on central political decisions. Given the increased role that wind power is supposed to play in Swedish energy supply, it is perhaps inevitable that some decisions are taken centrally. Yet, this entails limitations concerning the possibilities of participating and influencing the planning and decision-making process. Moreover, the high, political level of certain decisions is a challenge for entrepreneurs in creating public participation in such parts of the issue that people find meaningful to engage in. However, the possibility of using municipal veto against wind power projects is one main principle where influence can be exercised on a local level. This principle creates pressure on central authorities to secure support for the national objectives of wind power expansion, and on the entrepreneurs to get support for specific projects in the local community. Our analysis shows the importance of people knowing about a plant early in the process - and indeed to be part of some decision making - to create legitimacy for the process, and ultimately legitimacy for the specific wind farm. In order to create participation it is important to have a dialogue where all participants take part in the discussion with an open mind to new facts and perspectives, and that all experiences and concerns are treated with respect. In this report we have stressed the economic part as being a potential for active, local involvement in wind energy issues. From this study however, we want to emphasize the importance of distinguishing between different forms of economic participation.

Violent Interaction Detection in Video Based on Deep Learning

Violent interaction detection is of vital importance in some video surveillance scenarios like railway stations, prisons or psychiatric centres. Existing vision-based methods are mainly based on hand-crafted features such as statistic features between motion regions, leading to a poor adaptability to another dataset. En lightened by the development of convolutional networks on common activity recognition, we construct a FightNet to represent the complicated visual violence interaction. In this paper, a new input modality, image acceleration field is proposed to better extract the motion attributes. Firstly, each video is framed as RGB images. Secondly, optical flow field is computed using the consecutive frames and acceleration field is obtained according to the optical flow field. Thirdly, the FightNet is trained with three kinds of input modalities, i.e., RGB images for spatial networks, optical flow images and acceleration images for temporal networks. By fusing results from different inputs, we conclude whether a video tells a violent event or not. To provide researchers a common ground for comparison, we have collected a violent interaction dataset (VID), containing 2314 videos with 1077 fight ones and 1237 no-fight ones. By comparison with other algorithms, experimental results demonstrate that the proposed model for violent interaction detection shows higher accuracy and better robustness.

The aim of this study was to make a survey over the physical parameters and how they affect the image quality and the final diagnosis for myocardial perfusion SPECT in Sweden. Another aim was to evaluate the need for standardized acquisition and processing protocols for myocardial perfusion SPECT. All thirty nuclear medicine departments in Sweden that perform myocardial perfusion SPECT participated in the study. A thorax heart phantom was used to simulate two patients. All studies were acquired and processed with the parameters used clinically in each hospital respectively. A quantitative and a qualitative evaluation were performed. At each hospital, the local nuclear medicine physician interpreted the images as if they were true patient images. There are great differences in the acquiring and processing parameters used in myocardial perfusion SPECT studies in Sweden. The image quality varies greatly for the different hospital but was approved for the majority of the hospitals. Images from two hospitals were considered to be too poor to be diagnosed. The interpretations of the local nuclear medicine physicians differ but the majority has reported an adequate diagnosis. One third of the hospitals have reported false positive defects. All steps in the chain from the acquisition to the evaluation of the medicine physician must be performed with high quality. The determinative factors are the noise reduction filter, the orientation of the slices in the heart and the judgement of the local medicine physician. The acquiring and processing parameters proposed by EANM should be used. The hospitals are also recommended to investigate in the time and resources available, in order to educate all staff involved in the evaluation of myocardial studies

The combustion of waste implies a risk for deposits and corrosion in different parts of the combustion facility. In recent years, research and tests have been performed in order to find ways to mitigate these problems in waste-fired plants. Most waste-fired plants in Sweden are grates whereas most of the research has been carried out in fluidized bed plants. The purpose of this project is to examine whether co-firing of sewage sludge and waste can reduce deposition and corrosion also in grate-fired boilers as has been shown in fludised beds. The objective is to determine the deposit growth and its composition as well as describing the initial corrosion attack. Representing sulphur-rich waste, elementary sulphur is also added to the waste and thereby compared with sludge as an additive. The target groups for this project are plant owners, researchers, consultants and authorities. Tests were performed in a 15 MWth waste-fired boiler with moving grate at Gaerstadverket, Tekniska Verken (Linkoeping). The boiler produces saturated steam of 17 bars and 207 deg C, and the normal fuel mixture contains of household and industry waste. The results show that co-firing with as heigh as 20 weight-% SLF (25 energy-%) was possible from an operational point of view, but the deposit rate increased especially at the two warmest positions. Generally the deposit rate was highest in the position closest to the boiler and decreased further downstream. During the tests a lot higher amount of SLF than normal was used (recommended mix is 5-10 % of SLF) this to be able to see effects of the different measures. Up to 23 weight-% of the rather moist sewage sludge was possible to fire when co-firing waste and SLF, without addition of oil. By adding sludge the deposit rate decreased but the increase upon adding SLF to ordinary waste was not totally eliminated. In the tests 'Avfall and SLF' the deposits were rich in chlorine. High concentrations of metal chlorides were found in the interface between the steel and the metal oxide. This weakens the adhesion of the oxide to the steel surface and thus increases the corrosion rate. By addition of sewage sludge or sulphur the initial corrosion was decreased on both the low-alloyed steel T22 and the stainless steel 304L; sewage sludge being a little better than sulphur. Qualitatively, the corrosion attack firing SLF was similar to that firing ordinary waste, but the attack was stronger. At material temperatures of 500 deg C and 420 deg C - corresponding to superheaters - alkali chloride corrosion dominated, while at 280 deg C - corresponding to furnace walls - a melt of KCl/ZnCl2 is likely to have accelerated the corrosion. This difference between different material temperatures was especially pronounced in the 'Avfall and the SLF' cases. Higher zinc content in the fuel can therefore increase risk of corrosion. The higher content of iron, lead, copper and zink in the ash from the SLF case corresponds to the content of SLF compared with ordinary waste. Comparing the present tests with similar tests in fludised beds, grate firing resulted in higher deposit rate on the exposed test rings. This can at least partly be attributed to the lack of empty pass in the present grate boiler and to some differences in fuel composition: more chlorine and less sulphur in the waste used in this project. However, the effect of adding sludge was similar but not as strong as in the fluidised bed tests. To summarise, the results show that co-firing SLF with sludge can be advantageous also in a grate-fired boiler. Because of the high heating value of SLF, this combination also makes it possible to add a high fraction of moist sewage sludge.

Full Text Available El potencial hídrico foliar (ΨL es una variable frecuentemente utilizada para medir el estado hídrico de los cultivos. Su medición con cámara de presión, es lenta, lo que impide tomar un gran número de muestras. El objetivo del trabajo fue evaluar métodos alternativos para estimar el ΨL mediante sensores remotos. Uno de los métodos evaluados fue el de la reflectancia espectral. Esta técnica requiere de análisis estadísticos para poder estimar las variables de interés. Se probaron dos análisis, el cálculo de índices a partir de los valores del espectro y el análisis de Mínimos Cuadrados Parciales (PLS. El otro método probado fue la termografía que registra las temperaturas de la canopia (TC, las cuales se relacionan con su estado hídrico. Los datos termométricos sirvieron para construir dos modelos de regresión que estimaron ΨL. Uno de los modelos fue una regresión simple con TC vs. ΨL; el otro fue una regresión múltiple construida junto con el “índice normalizado de vegetación” (NDVI = ((R900-R680/( R900-R680 y con el “índice hídrico” (WI = (R900/R970. El ensayo se llevó a cabo en un viñedo de la variedad Malbec, en Mendoza, Argentina. La reflectancia se midió durante la mañana y el ΨL al mediodía, paralelamente a la toma de imágenes termográficas. Por PLS, usando las reflectancias entre 325 y 1075 nm se pudo predecir el ΨL. Por regresión se obtuvieron las ecuaciones ΨL = -1,21659 + 0,445078 * TC; R2 =0,19, p = 0,0000 y ΨL = 1,83399 – 0,613766 * NDVI + 0,0447517 * TC -1,45787 * WI, R2 = 0,36, p = 0,0000. Al mapear mediante krigeado los ΨL observados y los estimados por los tres procedimientos, para analizar las similitudes en distribución espacial, se observó una apreciable semejanza entre ellos, a pesar de los bajos coeficientes de regresión encontrados. Aparentemente, los planos incluyen información espacial ausente en las regresiones. Se halló una mayor semejanza entre el ΨL observado y el estimado por PLS, comparado con los otros métodos.

A primary demand for a good indoor climate in a building is that temperature and humidity are maintained at comfortable levels, regardless of the prevailing outdoor climate. Some buildings often have a heat surplus for a great part of the year due to internal activities, even in climates with moderate ambient temperatures. This heat surplus has to be removed in order to fulfil the specified requirements on the indoor climate. The focus in this report is on possibilities and limitations using evaporative and desiccant cooling to satisfy the cooling demands in such buildings. Today the most common technical solution is to use a compressor refrigeration system for air-conditioning. As a result of the greenhouse effect and the ozone depletion debate, the prerequisites for compressor refrigeration systems have been changed. Evaporative cooling is an interesting alternative to conventional compressor refrigeration systems. However, the use of evaporative cooling presupposes all-air systems. The use of such a system will also, to a large extent, be limited by ambient conditions as well as the settled demands on the indoor climate. High outdoor humidity levels have great influence on the supply-air temperature achievable, i.e., cooling loads possible to meet. One way to considerably reduce the influence of these limitations is to use desiccant cooling, i.e., to dehumidify the ambient air before the evaporative stages. In this report, a general methodology to describe possibilities and limitations for evaporative and desiccant cooling, is presented. The major advantage of this methodology is that it may give rise to an increased understanding of these processes and, hence, be a guide to a proper dimensioning.

During the last years ashes form the CFB boiler in Perstorp has been utilised as a filler material, with success, in concrete production at Sydsten, Malmoe, Sweden. To examine the potential of using Swedish fly ashes as a filler material in concrete production, have different Swedish fly ashes above been studied to see if they fit the requirements for a filler material. The fly ashes studied in the project can be divided into four different groups, considering fuel mix and boiler type; 1. Bio and sludge fired CFB/BFB boiler from the paper industry, 2. Bio and peat fired CFB/BFB boiler, 3. Pulverized peat/coal firing furnace, 4.Bio and peat fired grate-fired boiler. From Sydsten experiences of using Swedish fly ashes two demands have emerged concerning the chemical composition of the ashes. The total amount of chloride in the concrete should not be higher than 0,1% and the LOI, (Loss Of Ignition) must be less than 10 %. The different ash analyses showed that the fluidised bed boilers and pulverized firing furnaces, in this study, passed all the chemical requirements but the grate fire boilers had difficulties to fulfil the requirement of LOI. The ashes chosen to be studied in further rheological investigations in different fresh concrete mixtures were, Category 1 (Hallstavik's and Hyltebruk's papermill), Category 2 (Vaesteraas Vaermeverk och Vaertaverket) and from Category 3 (Vattenfall Vaerme Uppsala). The results presented an increased water consumption of ashes from paper mills comparing with the other ashes, a probable reason could be the shape of the ash grains. The experiments also showed that all ashes contributed to the final strength of the hardened concrete, the paper mill ashes also contributed to the initial strength development. During mixture of the fresh concrete with an ash quantity of 60 kg/m{sup 3}, it different degrees of loss of consistency was observed during the first hour after mixing. When decreasing the amount of ash to 30 kg/km{sup 3}, it was only the paper mill ashes that could not maintain the consistency during the first hour. The mechanisms that are dominating in the interaction between ash and cement during the hardening of the fresh concrete are complex. The reasons why certain ashes create a greater loss of consistency than others are not fully understood. It is necessary to continue research in this issue for simplifying the choices when using ashes in different concrete application. This project resulted in full-scale demonstration. Sydsten in Malmoe delivered concrete with ash from the pulverized peat-firing furnace in Uppsala as a filler material to a concrete casting in Lund. The concreting was very successful. The concrete did not loose the consistency as noted in the laboratory experiments. The concrete also demonstrated an excellent workability. The overall conclusion is, some of the Swedish fly ashes are very suitable to use as a filler material in concrete. A full-scale demonstration and delivery to customer has already been made in south of Sweden (Sydsten). There is also potential to find methods to refine ashes, which today don't fulfil the requirements of consistency for example sieving, to reduce the quantity of LOI.

This report describes bias-test of manual and mechanical sampling systems of bio-fuels at 6 Swedish plants. Two parallel series of 30 samples each were taken at each plant. One series of samples was taken by the normal procedure. The samples of the other series were taken by a reference method. Either by stopped belt and taking a full cut using a sampling frame or by manual increment division of a whole truck-load was used with the assistance of a pay-loader. The rectangular pile formed was divided in 120 squares. Some of the sampling systems gave biased samples. This was due to drawing too small increments, having too small openings of the sampling tools and making errors in sample preparation. Determination of moisture was more accurate than determination of ash content. Ash is more heterogeneously distributed in biofuels than moisture. Ash bearing components as clay or stone segregate easily. Although the project has not been able to show that mechanical sampling gives a more representative moisture sampling than manual sampling, it is recommended to invest in mechanical sampling if possible. The reason for this is to reduce the risk of human error and for safety reasons. 14 refs, figs, tabs, photos

Human Reliability Analysis. Applicability of the HRA-concept in maintenance shutdown; Analys av maensklig tillfoerlitlighet. HRA-begreppets tillaempbarhet vid revisionsavstaellning

Obenius, Aino (MTO Psykologi AB, Stockholm (SE))

Probabilistic Safety Analysis (PSA) is performed for Swedish nuclear power plants in order to make predictions and improvements of system safety. The analysis of the Three Mile Island and Chernobyl accidents contributed to broaden the approach to nuclear power plant safety. A system perspective focusing on the interaction between aspects of Man, Technology and Organization (MTO) emerged in addition to the development of Human Factors knowledge. To take the human influence on the technical system into consideration when performing PSAs, a Human Reliability Analysis (HRA) is performed. PSA is performed for different stages and plant operating states, and the current state of Swedish analyses is Low power and Shutdown (LPSD), also called Shutdown PSA (SPSA). The purpose of this master's thesis is to describe methods and basic models used when analysing human reliability for the LPSD state. The following questions are at issue: 1. How can the LPSD state be characterised and defined? 2. What is important to take into consideration when performing a LPSD HRA? 3. How can human behaviour be modelled for a LPSD risk analysis? 4. According to available empirical material, how are the questions above treated in performed analysis of human operation during LPSD? 5. How does the result of the questions above affect the way methods for analysis of LPSD could and/or should be developed? The procedure of this project has mainly consisted of literature studies of available theory for modelling of human behaviour and risk analysis of the LPSD state. This study regards analysis of planned outages when maintenance, fuel change, tests and inspections are performed. The outage period is characterised by planned maintenance activities performed in rotating 3-shifts, around the clock, as well as many of the persons performing work tasks on the plant being external contractors. The working conditions are characterised by stress due to heat, radiation and physically demanding or monotonous work tasks. Errors and mistakes during this plant operating state may have severe consequences, both on the immediate work, as well as on the future power production. The human influence on the technical system is of great importance when analysing the LPSD condition. This should also affect the basis and performance of the analysis, to make as a realistic analysis as possible. When analysing human operation during LPSD, a holistic perspective should be used. A way to take the human abilities and performance variability into consideration is important. The study of performed analysis of human reliability for the LPSD condition shows, that the normative and/or descriptive approach and the linear cause-effect model are used. The main objective of HRAs performed within SPSAs is the quantification of human interaction and error frequency. Modelling of human behaviour in complex, sociotechnical systems differs in theory and practice. A reason may be that models as the one for functional resonance, not yet are applicable for practising analysts, due to a lack of well tried methods and the fact that analysis of the LPSD condition is performed in the PSA concept, which defines the type of results sought from the HRA, i.e. probabilities for human error. LPSD analysis methods need to be further evaluated, validated and developed. The basis for the analysis should, instead of PSA, be a holistic analysis according to how Man, Technology and Organization affect the system and plant safety. To achieve this, further activities could be to perform an in-depth study of existing analysis of the LPSD condition, to develop specifications of requirement for LPSD analysis, to further validate the HRA work process as well as to further develop practically applicable methods for human performance and variability analysis in sociotechnical systems

Radiation doses from the use of peat-fuel in heating power plants; Straaldoser vid anvaendning av torvbraensle i stora anlaeggningar

Energy Technology Data Exchange (ETDEWEB)

Moere, Hans; Hubbard, Lynn Marie

2003-02-01

The radiation doses and the need for radiological protection arising from the use of peat-fuel that contain naturally occurring radionuclides and 137 Cs are assessed. Dose calculations for the worst case are performed for two reference ashes, one containing normal concentrations of radionuclides and the other containing high concentrations. The concentrations of radionuclides in the normally active ash reflect the median value of U and Th in energy producing peat bogs. The concentrations in the highly active ash were chosen in such a way that not more than 5 percent of the peat bogs would exceed the values. The doses have been estimated for workers and the general public for different exposure pathways. These are 1) harvesting and handling of peat, 2) releases from heating plants, 3) land filling, 4) landscaping and 5) handling of ashes. Under normal circumstances the resulting doses from the normally active ash are insignificant (<0.01 mSv/year). For the highly active ash the doses are below 0.1 mSv/year under the assumptions made in the investigation. For the general public the doses are also insignificant for the highly active ash except for the influence of a landfill. The dose estimates of the influence from leached water from a landfill are very uncertain due to that too few measurements of environmental samples have been carried out. At today's production of 3.5 TWh per year the peat-ash can amount to between 30,000 and 60,000 tons per year. Today the Swedish Geological Survey limits the dose from peat-use informally. They advise against the harvesting of peat with a uranium content exceeding 200 ppm in an ashed peat sample, which corresponds to 2,470 Bq/kg of 238 U. The resulting doses are estimated to be about half of those estimated for the highly active ash. Thus 10 percent of otherwise suitable peat land is not harvested.

The project comprised several, mutually dependent, sub-projects; mapping, investigation of ways to reduce water consumption, membrane tests aiming to find ways to recover sugar, and pinch analysis to evaluate the possibilities for improved process integration. This final report deals with the overall project results. Identified savings opportunities and savings potentials are presented. The presented measures represent an overall optimisation based on the results of all the project parts. Already during the project, measures have been implemented that are calculated to save 65 000 m{sup 3} water annually, corresponding to 10 % of the total water consumption. This saving is in level with the goals for the project. In the table below, these and additional measures are presented with a total savings potential at approximately 200 000 m{sup 3} /year water. The project will then achieve a saving of just below 35 % of present water consumption. Also in the membrane study the results surpassed the expectations. It was found that with nano filtering a sugar concentration of more than 10 %(W) could be reached in the retentate at a flux 50al/m{sup 2}h. The total sugar losses were less than 5 %, i.e. 95 % should be possible to recover. In total, a savings potential of more than 300 tonnes sugar per year is indicated. The Energy savings in the project are calculated to 7,4 GWh/year, of which 0,2 GWh/year by reduced water consumption, 0,6 GWh/year by water recovery, 1,4 GWh/year by membrane technology and 5,2aGWh/year as a result of process integration. This should be compared to the target 2,5 GWh/year. Hence, the results are almost three times the expected. The savings in monetary terms are estimated at just under SEK 5 million per year. The investment is roughly estimated at between SEK 5 and 6 million, of which SEK 4 million for the membrane equipment and SEK 0,5 million for a process water buffer tank. The remaining investment costs cover heat exchangers, control equipment and piping. This means that the total package will have a payback time of approximately one year. The environmental benefits of this project are mainly a result of the reduced energy consumption. This leads to a 1 600 tonne reduction of carbon dioxide emissions annually from reduced natural gas firing. Furthermore, the results indicate possibilities for a profitable reduction of oxygen depleting substances by over 300 tonnes sugar annually. In addition, the reduction of water consumption by 200 000 cubic meters per year results in reduced electricity and chemicals consumption in both water and sewage treatment plants.

A full-scale lower wing panel made of composite material has been designed, manufactured and sensorised within the European Funded research project named SARISTU. The authors contributed to the whole development of the system, from design to implementation as well as to the impacts campaign phase where Barely Visible and Visible Damages (BVID and VID) are to be artificially induced on the panel by a pneumatic impact machine. This work summarise part of the experimental results related to damages production, their assessment by C-SCAN as reference NDT method as well as damage detection of delimitations by a guided waves based SHM. The SHM system is made by customized piezoelectric patches secondary bonded on the wing plate acting both as guided waves sources and receivers. The paper will deal mostly with the experimental impact campaign and the signal analyses carried out to extract the metrics more sensitive to damages induced. Image reconstruction of the damages dimensions and shapes will be also described based mostly on the combination of metrics maps over the plate partial surfaces. Finally a comparison of damages maps obtained by the SHM approach and those obtained by "classic" C-SCAN will be presented analyzing briefly pros and cons of the two different approached as a combination to the most effective structural maintenance scenario of a commercial aircraft.

Intra- and interpopulation relationships and taxonomic status of Pinus nigra Arnold in Croatia according to morphology and anatomy of needles

Full Text Available Intra- and interpopulational relationships and taxonomic status of six natural black pine populations (Pinus nigra Arnold from Croatia were analyzed. Special attention in this research was paid to the establishment of taxonomic status and distribution of stenoendemic Dalmatian black pine (Pinus nigra Arnold subsp. dalmatica (Vis. Franco. Three morphological and twenty-one anatomical traits of needles were used as well as analysis by the methods of multivariate statistics. Most of the researched individuals showed strong population affiliation, whereas a clinal transition of morphological and anatomical traits of needles was determined among the populations. The opinion of the existence of three subspecies of black pine on the territory of Republic of Croatia (Pinus nigra Arnold subsp. nigra, Pinus nigra Arnold subsp. dalmatica (Vis. Franco and Pinus nigra Arnold subsp. illyrica (Vid. Fukarek was confirmed. For each of the three subspecies new ranges were represented. Four Croatian populations were included in the stenoendemic subspecies of the Dalmatian black pine (Brač, Hvar, Grobnik and Pelješac, and a new distribution, broken in two, was suggested. Since the Dalmatian black pine has been reduced to several populations only, and there are some signs of continuous diminishing of its range, this research points out the need of making an action plan to preserve all natural populations of this subspecies.

Full Text Available En 2014, au sein du laboratoire ICAR (équipe InSitu / Cellule Corpus Complexe un projet appelé “Petits Films” a été conduit avec une double finalité : confectionner des petits films à partir de trois différents corpus et parallèlement mener une réflexion sur les modalités de réalisation, les finalités et les contraintes de ce type de réalisation. On considère que dans le domaine de l’analyse conversationnelle, dans lequel les chercheurs recourent de plus en plus à des corpus de données vidéo, la réalisation d’un petit film peut représenter non seulement un retour pour les participants, mais aussi un moyen de valorisation du corpus, d’un type d’approche en linguistique et plus largement de l’activité du laboratoire de recherche. Grâce à leur forme agréable et à leur courte durée, les petits films sont conçus pour la diffusion et la valorisation des méthodologies et des recherches, ils sont accessibles pour un large public, même de non-experts. Cependant, il est nécessaire de réfléchir aux questions juridiques et déontologiques que soulève cette opération.

Radioactive discharges and environmental monitoring at the Swedish nuclear facilities 2002-2004; Utslaepps- och omgivningskontroll vid de kaerntekniska anlaeggningarna 2002-2004

According to Swedish regulations the effective dose to an individual in the critical group, from one year of releases of radioactive substances to air and water from all facilities located in the same geographically delimited area, shall not exceed 0.1 mSv. The effective dose, which concerns the dose from external radiation and the committed effective dose from internal radiation, shall be integrated over a period of 50 years. When calculating the dose to individuals in the critical group, both children and adults shall be taken into consideration. If the calculated dose exceeds 0.01 mSv per calendar year, realistic calculations of radiation doses shall be conducted for the most affected area. SSI has not defined any radionuclide specific discharge limits. Limitation of releases is being implemented through the restriction of dose to the critical group members. For each nuclear facility, e.g. each reactor, and for each radionuclide that may be released, specific release-to-dose factors have been calculated. The factors have been calculated for hypothetical critical groups, and take into consideration local dispersion conditions in air and in the environment, local settlements, local production of food-stuffs as well as moderately conservative assumptions on diet and contribution of locally produced food-stuff to the diet of the group. For nuclear power reactors, release-to-dose factors (mSv/Bq) have been calculated for 97 radionuclides that may be discharged to the marine environment and 159 radionuclides that may be emitted to air. Discharges shall be controlled through the measurement of representative samples for each release pathway. The analyses shall include nuclide-specific measurements of gamma and alpha-emitting radioactive substances as well as, where relevant, strontium-90 and tritium. The discharges of radioactive substances from the Swedish NPPs result in very low doses well below the limits issued by SSI. Even so, the concentration of radionuclides in the discharges is relatively high compared to the similar facilities abroad. The main reasons are that the Swedish NPPs are situated at the seaside of the Baltic and Kattegatt Sea respectively, and that the radionuclides are released into a larger water volume and thus disperse easily. The environmental monitoring programme is issued by the SSI and specify type of sampling, sample treatment, radionuclides considered, reporting, etc. The site-specific monitoring programmes vary depending on the facility and are divided in a terrestrial and an aquatic part. The selection of environmental samples (biota and sediments) has been conducted in order to be highly representative of the area around the facility and to, preferably, be similar for all facilities. Also some of the species have been selected because they are part of the human food chain. Every year a basic programme involving spring and autumn sampling is conducted. Furthermore, certain samples are taken on a monthly and quarterly basis. In addition to the basic programme, extended sampling is also conducted every fourth year at most of the facilities. The extended programme focuses exclusively on samples taken in the marine environment. The environmental samples consist of local flora and fauna e.g. algae, fish, shellfish, mosses, game and sediment as well as local food products (grain, milk etc.). The samples are collected from either rope or plexiglass surfaces that are placed in the discharge water stream or outlet from the NPPs. These samples are collected monthly by manually scraping off the diatomic algae from the rope or plexiglass. The algae that are sampled are generally good bio accumulators for radionuclides. This quality together with the monthly sampling in the near vicinity of the outlet point makes diatomic algae a good bio indicator for the amount og discharges radionuclides and also take into consideration their variation in time. A selection of data from the environmental sampling programme for the years 2002-2004 for the Swedish NPPs, Studsvik and Westinghouse Electric Sweden AB, are given in Annex D. Apart from these tables some more data and graphs are given for Oskarshamn, Studsvik, Forsmark and Ringhals. This is due to the fact that during the time period 2002-2004 an extended sampling has taken place. The data from environment samples shows that the discharges give low but measurable concentrations of radionuclides in samples taken in the marine vicinity of the outlet. The concentrations of radionuclides are very low. Measurements of e.g. Co-60 shows varying low concentrations for the time interval 1983-2004 and no long-time trend can be discerned. SSI undertakes a number of checks of the measurements performed by the operator, concerning gamma emitters, alpha emitters, tritium and strontium-90. Pooled and stabilised annual samples from each monitored waste water stream shall be sent to the SSI within three months after the end of the discharge year. In addition a number of randomly chosen monthly samples of waste water are analysed by SSI. The annual samples are measured concerning gamma emitters and tritium by the SSI and the results are compared with the data submitted by the operators. These measurements are conducted at the SSI laboratories. Control measurements of Sr-90 and alpha-emitting radionuclides are performed on a case by case basis at independent external laboratories. Aerosol filters shall be sent to the SSI for control measurements on request. Normally, this exercise is performed once a year, and the filters are subjected to gamma-spectrometric analyses. Environmental measurements are checked by the SSI. A total number of up to 50 samples, obtained as sub-samples of the material analysed by the operator or the laboratory contracted by the operator, is analysed annually. All tables and all graphs have captions in both Swedish and English.

There is a potential for cereal grain for combustion use in Sweden, as well as for other agricultural fuels with similar qualities. Today, grain is combusted mainly in small-scale appliances. As all fast growing crops, the ash content is higher compared to wood fuels, resulting in a higher emission of particles. There are no limits for particle emission from appliances smaller than 500 kW in Sweden today. Nevertheless, it is important to consider these emissions because dust from small scale combustion of biofuels is one of the larger sources of particles to air in Sweden and in Europe today. Lately, is has been observed that the ultra fine particles (< 0.1 mum) is a cause of increased mortality. During large-scale combustion, the flue gas is cleaned from particles by electrostatic or fabric filters. During small-scale combustion primary measures is preferred by economical reasons. Particles can be reduced by design of the appliances or control of the combustion process. It might also be possible to reduce particles by use of additives that ties the volatile matters to the bottom ash and/or causes them leave as gas instead of particles. The aim of this project is to characterize and reduce particle emissions from combustion of cereal grain by use of additives. Limestone and kaolin were tested in a burner for oat grain. Particle emission was measured as total dust, as mass size distributed and as number size distributed. Fuel, bottom ash and dust were characterized chemically. In the flue gas carbon monoxide, carbon dioxide, oxygen, hydrocarbons, nitrogen oxide, sulphur dioxide and hydrogen chloride was measured. Equilibrium calculations were performed for combustion with and without additives. The combustion was not negatively influenced by the additives. The results confirm that lime stone reduces emissions of acidifying and corrosive gases such as sulphur dioxide and hydrogen chloride. Both lime stone and kaolin increase the ash fusion temperature. Results from this project show that lime stone can reduce total dust, provided the lime is supplied in a proper way, and that the design and control is suited for additives. How the lime should be supplied, and what is the best design and control is still to be investigated. Kaolin can be used to reduce particles. In this project a supply to the fuel of 2 % kaolin lead to a 31 % reduction of particles, and supply of 4 % lead to a 57 % reduction of particles

Potential ecosystem effects caused by the effluent cooling water from the Simpevarp nuclear power plant, close to Oskarshamn on the Swedish coast of the Baltic Proper, are monitored in yearly surveys using gillnets and fyke nets. Fishing is undertaken at several sites in a coastal gradient starting at the location of the emitted cooling water, and in a reference area 100 km north of the recipient. Soft bottom macro fauna and macro vegetation are monitored both in the gradient and in the reference area. Fish mortality due to entrapment in the cooling water system and commercial landings are monitored to assess the effects on the local fishery. The water used for cooling is normally heated by 10-12 deg C when passing through the power plant. In sheltered parts of the recipient bay of Hamnefjaerden, the surface water was 4-6 deg C warmer in April-November 2011 than in the reference area comparable reference areas and the emitted water occasionally exceeded 30 deg C in the summer. Fish losses in the cooling water rinsing system were dominated by Baltic herring. Effects on abundances at the population level are estimated to be small, but local effects cannot be ruled out. Perch (Perca fluviatilis), roach (Rutilus rutilus) and silver bream (Blicca bjoerkna) dominated the catches in the surveys with gillnets in Hamnefjaerden, as well as in the archipelago surrounding the power plant. Perch abundances increased in these areas. Catches of roach decreased close to the power plant, but also in the reference area. Perch in the gillnet catches were younger and grew faster close to the power plant than in the reference area. Abnormal gonads, previously observed at high frequencies in perch and roach in Hamnefjaerden, were rare in the 2011 sampling. The abundance of young of the year perch in the recipient did not change over time. The size of the perch fry however, increased in Hamnefjaerden, as well as in the local reference area. The catch and size structure of yellow eel (Anguilla anguilla) did not change over time in the recipient since the 1980s. The prevalence of swim bladder parasites (Anguillicoloides sp.) has been 50-60% since the parasite was established in Hamnefjaerden in the late 1980's. Gillnet surveys are performed in the spring on the open coast at the power plant to study effects on Baltic herring and other marine species, normally appearing at low water temperatures. Problems due to an increasing population of grey seals forced a change in fishing methodology in 2011, and the pelagic nets were replaced with a series of demersal nets. The abundances of the long term dominants Baltic herring (Clupea harengus), sea scorpions (Myoxocephalus scorpius) and cod (Gadus morhua) have shown large periodic variations since the survey was established in the early 1970's. Cod alone has shown a long term decrease, probably reflecting the general situation in the Baltic Sea. Silver eel (Anguilla anguilla) catches decreased in the local fishery, but increased in the reference area until silver eel fishing stopped in this area in 2001. The long term development is however believed to reflect the general trends of eel in the Baltic region. Abundance and species richness in soft bottom macro fauna increased strongly in shallow sites between 1962-2011, in Simpevarp as well as in the reference area. The number of species increased also on deeper sites, but the total abundance did not change significantly. The abundance of the introduced polychaete Marenzelleria sp. increased rapidly in recent years and is now among the dominants in both areas. The trend is reflective of the general changes in the Baltic Sea. Vegetation on hard bottoms is monitored on three sites in the coastal gradient of cooling water. The algal communities are considered to have good ecological status and the studied sites are among the richest in the region. The Fucus vesiculosus cover decreased however, in recent years due to the wearing of ice. Fucus increased its distribution in deeper parts in two sites south of the power plant. The cover of filamentous green algae increased over the last decade and the cover of red algae in 5-6 m depth decreased in recent years.

Alkali and chlorine in biomass - a problem in connection with power generation. Alkali och klor i biomassa - ett problem vid elgenerering

Energy Technology Data Exchange (ETDEWEB)

Gaerdenaes, S

1991-06-04

The literature survey gives a summary of the macronutrients and the variations in different biomass. Especially alkali is discussed. The work gives an account of difficult biomass fuels which will rather be used in hot water boilers than in gas turbines of power generation. The amount of alkali and chlorine increases from hardwood < softwood < salix < straw from Phalaris arundineral (harvested during summer). The range of variation was 10-25 between the assortments. The fraction division is the most important factor for the variation. Alkaline content also depend on age, soil fertility and storage methods. Seasonal aspects and local depositions are less important. However, great care should be taken with fuel from coastal areas because of chlorine depositions. Gasification of biomass to produce gas for combined cycle operation poses special problems. The alkali content of logging residues have to be cleaned up to approximately 99 % in the example. When the process gas is originated from straw or salix the separation have to be even more efficient. The method used for the separation could be based on wet or dry technic hotgas cleanup has not yet been tested in large scale but seems to be a promising method to attain high degree of separation and power efficiency. Difficulties of power generation make straw fuels less interesting. The content of alkali and chlorine can be considerably decreased by changing the way of fertilization and cultivation period. If everything turns out well, this would give a complementary for gasification or steam generation. To the greates part this fuels will however be used in pure heat production. (author).

The purpose of this report is to examine how the planning preparedness offshore unfolds. Planning conditions of municipalities have been investigated through interviews with municipal planners and representatives of the wind power stakeholders. At the same time, the problems and deficiencies that impede the expansion of offshore wind power have been identified. In the report, based on the survey of the state of planning, as well as the shortcomings of current systems, the Swedish National Board of Housing, Building and Planning presents opportunities for improvements. With these proposals the Swedish National Board of Housing, Building and Planning opens up for an increased cooperation with the aim to facilitate a future expansion of offshore wind power. The report primarily addresses central government agencies and authorities, county councils, as well as planners or other officers of the national, regional and municipal levels

Mechanical pre-treatment for enzymatically enhanced energy efficient TMP; Mekanisk foerbehandling av flis foer effektiv enzymatisk paaverkan vid energieffektiv TMP tillverkning

Energy Technology Data Exchange (ETDEWEB)

Viforr, Silvia

Thermomechanical pulp (TMP) processes are high energy demanding. This together with the high energy prices of nowadays results in significant costs, why less energy demanding processes are wished. This project has evaluated the potential for energy reductions in a TMP process by a mechanical pre-treatment of the wood chips combined with an enzymatic modification based on a cellulase mixture. The structure of the wood was opened up by the mechanical pre-treatment making it easier for the enzymes to penetrate into the pre-treated wood material. The enzymatic treatment was then run at optimum standard conditions. The EU project - Ecotarget 2004-2008 (www.ecotarget.com) have studied different types of enzymes that could be used for pre-treatment of wood chips in order to save energy during TMP processes. Based on these studies cellulose enzyme was recommended to be used at pre-treatment experiment performed by the Vaermeforsk project. Due to the fact that the Ecotarget-project has also been run during 2008 with activities involving enzymes, the steering board of the Vaermeforsk project took the decision to co-ordinate the experiments from both of the projects. This co-operation increased the funds and also the number of experiments for both of the projects. The experimental results from this project showed that energy reductions at a given tensile index could be achieved if gently mechanical pre-treated wood chips were enzymatically treated. An intensive mechanical pre-treatment gave negative effects on both fibre length and tear index while the light scattering coefficient was promoted, probably due to the fibre shortening. Enzymatic modification of mechanically pre-treated chips showed a favourable modification of the fibres, even regarding the fibre shortening, if compared to mechanical pre-treated chips only. The effects of cellulases was however not as expected, why a high amount of cellulases was used. Other types of enzymes which could attack the primary wall of the wood cell should be tested in mechanical pre-treatment of wood chips for energy savings in TMP processes. Such enzymes could be xylanases, pectinases or proteases. New equipments that could pre-treat wood chips more gently may also be desired

Abatement Technologies for Volatile Organic Compounds in Emissions from Biofuel Driers; Reningsteknik foer organiska aemnen i utslaepp till luft vid biobraensletorkning

This report is a part of a program at Vaermeforsk called Drying of Biofuels and deals with abatement technologies for volatile organic compounds (VOC) in biofuel drier emissions. The report gives an account of the amount of organic matter in wood and in drying gases and also of different abatement technologies for VOC. Processes from about 20 contractors are briefly described. The conclusions from this work are that thermal or catalytic oxidizing technologies in connection with regenerative heat recovery seems to be the most suitable technique for this application. Both technologies should give a degree of purification above 95 %. The purification cost for a typical case has been estimated to about 22 SEK per kg removed organic matter in both cases. The investment cost is higher for the catalytic oxidizer (6-20 MSEK for a 60.000 Nm{sup 3} /h catalytic plant compared to 4-6,5 MSEK for a thermal plant) but the fuel cost is lower. Condensation is a usable technique but it suffers from bad degree of purification. By using a wet electrostatic precipitator (WESP) the degree of purification can be enhanced but it will still be lower than for the oxidizers. Adsorption and absorption are not suitable for gases at high temperatures containing several different organic compounds at low concentrations, which is the case in biofuel drying. This means high purification costs and low degree of purification. Other technologies that have been found less suitable are biological purification and membrane technology. World-wide there are a few reference plants based on thermal oxidizing in connection with biofuel drying. Otherwise the experiences are very limited. According to this, tests in pilot plant scale are recommended before investment in a full-scale plant for biofuel driers.

Biological recipient control at the Ringhals nuclear power plant. Annual report for 2011; Biologisk recipientkontroll vid Ringhals kaernkraftverk. Aarsrapport foer 2011

The cooling system of the Ringhals nuclear power plant affects the fish community in two steps. In the first step, seawater is used to cool the system in the nuclear power plant. Fish eggs, larvae and small juveniles are carried by the incoming water and are exposed to risk of damage or mortality. In the second step the heated water is released back into the sea, where the fish is affected by the increase in temperature. Reactor 1 and reactor 3 at Ringhals nuclear power plant produced electricity during the major part of the year 2011, with exceptions for the annual audits, and shorter stops in production. Reactor 2 only operated between January and April, due to a fire which led to a shutdown and a thorough remediation work during the rest of the year. Reactor 4 was producing electricity from January to June, but was later shutdown due to a prolonged annual audit until November. Fish eggs and fish larvae are sampled in the incoming cooling water using a modified Bongo net to monitor losses of eggs and larvae in the nuclear power plant. The abundance of shorthorn sculpin larvae (Myoxocephalus scorpius) has decreased since the sampling period started, although it is still the most abundant larvae. Also the abundance of rock gunnel larvae (Pholis gunnellus) has decreased over the years. To sample juvenile fish a modified Isaacs-Kidd midwater-trawl is used. This sampling is mainly focused on glass eels (Anguilla anguilla). The abundance of glass eels have declined strongly since the beginning of the 1980's, but a minor increase was observed in 2011. The decline of the glass eel abundance is most probably due to a general decrease in recruitment and not to a local effect caused by the nuclear power plant. The effects of the heated water released into the sea are monitored by fykenet surveys in the recipient as well as in a reference area. These two areas are monitored in two seasons to compare differences between the two areas in naturally cold and warm water of the two seasons. There was a different development in the diversity of fish between the two areas in the cold season, where the recipient showed a decreasing trend in diversity and the reference area was stable with no trend. This is possibly an effect of the warm water emissions. Species which prefer warm water have been observed to concentrate in the recipient area. Eel and shore crabs (Carcinus maenas) are good examples, showing either stable or increasing catches in the area. Species which prefer cold water, as cod (Gadus morhua), shorthorn sculpin (Myoxocephalus scorpius) and eelpout (Zoarches viviparous) were less abundant in the recipient. No new findings for Swedish water of marine alien species were made in a scuba diving survey in four shallow areas near the outlet of cooling water from Ringhals (Ringhals udde, Baatafjorden, Norra Horta and Vendelsoe). Four species already established on the Swedish west coast were found however, the japanese oyster (Crassostrea gigas), two species of red algae Dasya baillouviana, Bonnemaisonia hamifera and one brown algae, the japanese wireweed (Sargassum muticum)

Les jeux de hasard chez les enfants et les adolescents

RÉSUMÉ Même si, au Canada, les mineurs n’ont pas le droit de jouer à des jeux de hasard légalisés, les adolescents participent souvent à des jeux de hasard soit légalisés (produits de loterie, casino, terminaux de jeux vidéo), soit autonomes (jeux de cartes, paris sportifs, dés) à la maison et en milieu scolaire. Chez les adultes, le taux de prévalence de dépendance aux jeux de hasard au cours de la vie se situe entre 1 % et 2 %. D’après les données existantes, la prévalence chez les adolescents serait de deux à quatre fois plus élevée. On ne sait pas grand-chose des facteurs de risque d’apparition et de perpétuation d’une dépendance pathologique aux jeux de hasard. Le présent document de principes vise à informer les pédiatres, les médecins de famille et les autres professionnels de la santé des connaissances émergentes sur les jeux de hasard pendant l’enfance et l’adolescence et du risque de conséquences graves qui s’y rattachent. On y exhorte également les gouvernements fédéral, provinciaux et territoriaux à inclure cette question dans leur programme et à tenir compte des facteurs sociopolitiques associés aux jeux de hasard.

La transformation de la politique sur Internet : de la politique-spectacle à la cyberdémocratie d’activisme citoyen

Full Text Available Les nouvelles technologies de la communication et de l’information appliquées à la communication politique sont en train de provoquer une transformation profonde de la représentation et de l’exercice de la politique dans les sociétés avancées. La plupart des nouvelles ressources de ce qu’on a commencé à appeler « la technopolitique » n’introduisent qu’une plus grande spectacularité, sentimentalisation et futilité dans la présentation des leaders, partis politiques et gouvernements face à la citoyenneté. Les vidéos politiques sur Youtube, le « marketing viral » et la « twitter-manie » augmentent certes l’impact scénique mais souvent aussi la distorsion propagandiste au détriment de l’analyse des propositions électorales et des réalités de la gestion politique. Cependant, ces mêmes technologies facilitent la création de nouveaux espaces de contrôle social, de délibération et suivi critique de la politique grâce à des mouvements citoyens qui profitent du potentiel des TIC pour avancer vers une « Démocratie 2.0 » ou « Cyberdémocratie » progressive. Quelques exemples choisis parmi les deux tendances permettront de comprendre les ombres et lumières de l’environnement numérique de la nouvelle communication politique.

X-ray survival characteristics and genetic analysis for nine saccharomyces deletion mutants that show altered radiation sensitivity

Energy Technology Data Exchange (ETDEWEB)

Game, John C.; Williamson, Marsha S.; Baccari, Clelia

2004-01-07

The availability of a genome-wide set of Saccharomyces deletion mutants provides a chance to identify all the yeast genes involved in DNA repair. Using X-rays, we are screening these mutants to identify additional genes that show increased sensitivity to the lethal effects of ionizing radiation. For each mutant identified as sensitive, we are confirming that the sensitivity phenotype co-segregates with the deletion allele and are obtaining multipoint survival-versus-dose assays in at least two haploid and one homozygous diploid strains. We present data for deletion mutants involving the genes DOT1, MDM20, NAT3, SPT7, SPT20, GCN5, HFI1, DCC1 and VID21/EAF1, and discuss their potential roles in repair. Eight of these genes have a clear radiation-sensitive phenotype when deleted, but the ninth, GCN5, has at most a borderline phenotype. None of the deletions confer substantial sensitivity to ultra-violet radiation, although one or two may confer marginal sensitivity. The DOT1 gene is of interest because its only known function is to methylate one lysine residue in the core of the histone H3 protein. We find that histone H3 mutants (supplied by K. Struhl) in which this residue is replaced by other amino-acids are also X-ray sensitive, seeming to confirm that methylation of the lysine-79 residue is required for effective repair of radiation damage.

For the first time, a multivariate approach combining targeted and untargeted data was used to obtain insight into quality changes in pasteurised mango juice (cv. 'Totapuri') as a function of storage (42°C for 8weeks). Mango juice samples were formulated with addition of different potential precursors for different quality-related chemical reactions: ascorbic acid, citric acid and sugars. Control (diluted mango puree with water), ascorbic acid-enriched (AA 250 and AA 500 ), citric acid-enriched (CA, CA+AA 250 and CA+AA 500 ) and sugar-enriched (S) samples were characterised for a range of targeted quality parameters as well as for a volatile fingerprint (untargeted). Selection of shelf-life markers or quality parameters significantly changing during shelf-life was performed over all formulations as well as per mango juice formulation. Our study showed that a common trend over all formulations was observed for colour values (VID>│0.90│), while specific shelf-life markers were selected for each formulation. In acidified mango juice samples (CA, CA+AA 250 , CA+AA 500 ), more terpene oxides were selected compared to other formulations. In ascorbic acid-enriched samples (AA 250 , AA 500 , CA+AA 250 , CA+AA 500 ), furfural and ascorbic acid were significantly changing during shelf-life. It seems that the reaction pathways for compounds being formed or degraded upon shelf-life are clearly affected by the acidity level. Copyright © 2015 Elsevier Ltd. All rights reserved.

Résumé L’objectif de cette étude était de valider la version francophone de l’échelle composite multidimensionnelle de douleur UNESP-Botucatu (MCPS-Fr) chez les chats. Deux vétérinaires et une étudiante de médecine vétérinaire francophones ont identifié trois catégories de comportements distincts sur des vidéos : «les changements psychomoteurs», «la protection de la région douloureuse» et «les variables physiologiques». La cohérence interne était excellente (score total du coefficient alpha de Cronbach était de 0,94; 0,90; et 0,61, respectivement). La bonne concordance entre les évaluations à l’aveugle des observateurs et l’évaluateur de référence confirme la validité de cet instrument. La fiabilité inter- et intra-évaluateur était bonne à très bonne. Le point limite optimal pour l’analgésie de secours, identifié avec une courbe ROC, était au-delà de 7 (échelle allant de 0 à 30 points), avec une sensibilité de 97,8 % et une spécificité de 99,1 %. La MCPS-Fr est un outil valide et sensible pour l’évaluation de la douleur aiguë chez les chattes ayant subi une ovariohystérectomie. PMID:28042156

Ionic Liquids as Novel Lubricants and /or Lubricant Additives

Energy Technology Data Exchange (ETDEWEB)

Qu, J. [ORNL; Viola, M. B. [General Motors Company

2013-10-31

This ORNL-GM CRADA developed ionic liquids (ILs) as novel lubricants or oil additives for engine lubrication. A new group of oil-miscible ILs have been designed and synthesized with high thermal stability, non-corrosiveness, excellent wettability, and most importantly effective anti-scuffing/anti-wear and friction reduction characteristics. Mechanistic analysis attributes the superior lubricating performance of IL additives to their physical and chemical interactions with metallic surfaces. Working with a leading lubricant formulation company, the team has successfully developed a prototype low-viscosity engine oil using a phosphonium-phosphate IL as an anti-wear additive. Tribological bench tests of the IL-additized formulated oil showed 20-33% lower friction in mixed and elastohydrodynamic lubrication and 38-92% lower wear in boundary lubrication when compared with commercial Mobil 1 and Mobil Clean 5W-30 engine oils. High-temperature, high load (HTHL) full-size engine tests confirmed the excellent anti-wear performance for the IL-additized engine oil. Sequence VID engine dynamometer tests demonstrated an improved fuel economy by >2% for this IL-additized engine oil benchmarked against the Mobil 1 5W-30 oil. In addition, accelerated catalyst aging tests suggest that the IL additive may potentially have less adverse impact on three-way catalysts compared to the conventional ZDDP. Follow-on research is needed for further development and optimization of IL chemistry and oil formulation to fully meet ILSAC GF-5 specifications and further enhance the automotive engine efficiency and durability.

In four fields in the south of Sweden different energy crops were tested. In all trials sugar beet, barley, alfalfa, corn, sunflower and quickgrowing species of Salix (energy forest) were grown. In some of the trials broome-grass, potatoes and winter wheat were tested. One trial also included marrow-stem kale, Jerusalem artichoke and a hybride of J artichoke and sunflower. The purpose of the experiment was to illustrate the effect of increasing N-fertilizing and the effect of growing the crops in different climatic conditions. The yield varies between the crops. Some of the crops were harvested in different stages of development. The largest yields were noticed for sugar beet, corn, potatoes and energy forest. For these crops the yield was 11.5-14.5 tons of dry matter per hectare. The yield of potatoes was very large but it is figures for only one place with very good conditions. Barley, sunflower and alfalfa produced 8-10 tons of dry matter per hectare. The smaller yield depends on a short vegetation season for these crops. The year of establishment the energy forest produced about four tons of dry matter in the form of stem wood. When fully established the production has been 12-15 tons of dry matter per hectare and annum. The analysis of plant material indicates small divergences in the content of carbon and heat value.

Evaluation of pine bark for treatment of water from biomass fueled plants; Utvaerdering av bark foer rening av vatten vid biobraensleeldade anlaeggningar

Energy Technology Data Exchange (ETDEWEB)

In Sweden, large amounts of pine bark are produced as a by-product from the pulp and forest industry. This makes pine bark available in large volumes to a relative low price. Pine bark has shown good absorption effect for organics pollutants, such as oil, in water and pine bark is used commercially as an oil absorbent. In a study the pine bark has also shown to have good absorption effects on heavy metals in water, in laboratory conditions. This indicates that pine bark also could be used as a natural absorbent for heavy metals in flue gas condensate and for leachate from biomass fuel storage. For the latter purpose the bark could be used as a combined heavy metal and oil absorber. In this project the pine barks ability to absorb heavy metals from flue gas condensate has been studied. The tests were performed using an untreated flue gas condensate, which was purified by using a basket filter with commercially available pine bark (trademark EcoBark) as absorbent. The bark filter has the same function as a tube reactor, which would imply that the absorption of heavy metals should be better than the laboratory tests. However, the results from the flue gas condensate tests showed much lower absorption of heavy metals than the laboratory tests. The only significant absorption levels were found for iron and mercury, which showed a reduction ratio of about 25 %. Other metals, such as lead, cadmium, copper, nickel, vanadium and zinc had a reduction ratio of about 10 %, which is quite low compared to the 98 % reduction for lead and about 80 % for copper and zinc that was achieved in the former laboratory tests. The most probable reason that the pine bark had a very low absorbent effect in the flue gas condensate is that the concentration of potassium and calcium restrains the ion exchange capacity of the pine bark. It is also likely that iron mainly is absorbed by the bark, while other metals only are separated as particles. Another possible reason for the rather poor absorption results in the flue gas condensate tests could be that iron affects the absorption of other metals. The water temperature could also have some influence on the results while the laboratory tests were performed at a considerably lower water temperature, 22 C. The flue gas condensate tests also included measurements of COD upstream and downstream the bark filter. The analyses shows that the COD concentration in the condensate upstream the filter is very low, 20-25 mg/litre, while the COD concentration downstream the filter is considerably higher, in the range 40 - 220 mg/litre. The COD before the filter probably originates from the small amount of char particles in the flue gas condensate and the increase of COD after the bark filter comes from humus that has been dissolved from the bark. The heavy metal absorption that has been analysed in the test with flue gas condensate should be comparable with heavy metal absorption from leachate from bio fuel storage, even if the water temperature in the latter case is lower.

Environmental aspects on LCF-life of Ni-base superalloys during long term operation; Miljoeinverkan paa LCF-egenskaper vid laanga drifttider hos superlegeringar

The applicability of fine grain polycrystalline nickel base superalloys in gas or steam turbine applications is often limited by their susceptibility to fast intergranular cracking during fatigue in combination with extended hold times at high temperatures and high tensile stresses. This effect is further enhanced in corrosive environments even at moderate temperatures such as 400-600 deg In this study the negative effect of SO{sub 2} + water vapour on the low cycle fatigue resistance of three different nickel based superalloys (Nimonic 901, Inconel 718 and 718 plus) has been studied at 450 deg and 550 deg. A negative effect was found on both the crack initiation and crack propagation process. The effect increases with increasing temperature and is likely to be influenced by both the chemical composition and the grain size of the material. The negative effect of water vapour + SO{sub 2} is manifested by a decreased resistance to cyclic plastic deformation and a transition from transcrystalline to intercrystalline fracture behaviour. In Nimonic 901 this negative effect increases with the degree of plastic deformation. For lower mechanical strain amplitudes where the number of cycles and the total exposure time is increased the environmental impact is reduced. Similar trends can also be noticed for the other alloys. The surface corrosion in air and in SO{sub 2} + water vapour are found to be rather similar in this study and it is therefore concluded that the surface scale can remain adherent and protective if the strains on the oxide scale are low. However, for LCF tests with higher strain ranges, the oxide scale will rupture preferably at the grain boundaries and intergranular microcracks will initiate which promotes inward diffusion of embritteling elements such as oxygen and sulphur. Inconel 718 seems to be more sensitive to SO{sub 2} + water vapour than Nimonic 901 when tested at 450. The overall resistance to LCF is however still higher in Inconel 718 for the test conditions investigated in this study, this is due to the exceptionally good resistance to low cycle fatigue that this alloy has from the start (as seen for the tests in air)

Konstruktion och undersökelse, exotism och närhet i Per Olof Sundmans böker om Lofoten

Directory of Open Access Journals (Sweden)

Annie Bourguinon

2007-04-01

Full Text Available The Swedish writer Per Olof Sundman (1922-1992 wrote mostly short stories and novels, but also reportages. The paper deals with two reportages from the Lofoten islands, Människor vid hav (1966, “People by the sea” and Lofoten, sommar (1973, “Lofoten, summer” The choice of the Lofoten islands as a subject is related to a fascination Sundman felt towards northern and arctic regions, a fascination he also expressed in a number of fictional narratives and in the documentary novel Ingenjör Andrées luftfärd (1967. English title: The Flight of the Eagle A question that arises almost immediately is whether that fascination affects the way the reporter works and how it affects it. How does Sundman look at the Lofoten? What does he take notice of and tell us about? What kind of image does he give? And how does he understand his own role, his function as an investigator in an environment which is neither his own nor his postulated readers’ usual environment? Another question deals with the relationship between the reportages from the Lofoten and the author’s other works. Are the reportages easy to recognize as Sundmanian texts, can Sundman’s “signature” be traced in them? It appears that “People by the sea” and “Lofoten, summer” are not merely informative texts. They also to a rather high degree suggest an atmosphere, using among other things inherited representations and judgements to that purpose. Those reportages turn out to be strongly literary texts, in the traditional meaning of the word.

Survey of development work and problems with different collection techniques of food waste; Kartlaeggning av utvecklingsarbete samt problem vid olika insamlingstekniker foer matavfall

Henriksson, Gunilla

2010-07-01

In accordance with Sweden's environmental objectives it has been decided that, by 2010, 35 per cent of all food waste shall be recovered through biological treatment. In order to get there, the problems regarding collection methods needs to be solved. There are several different collection systems to choose between, but at the present time there is no complete list of the methods and techniques available on the market. Lists of advantages and disadvantages with each system, of potential improvements, and of completed or ongoing development projects are also missing, and creating difficulties for municipalities and businesses which are planning on introducing a system. The goal with this study is to provide a survey of technical problems with different systems and to identify previous studies as well as new innovations within collection techniques. The expectation is that this work eventually will lead to improved collection systems. The study will cover existing collection techniques in households, large-scale kitchens, restaurants and grocery stores in Sweden. The study will only cover the so called hard parameters, i.e. primarily technical issues. The target group is on the one hand municipalities planning on starting collection of food waste and on the other hand all actors in the area, such as innovators, producers and suppliers as well as Waste Refinery's organizations. Soft issues such as issues regarding information and quality are not included. The system limits of this project span between the recycling equipment of homes and businesses to the food waste's treatment at the biological treatment plant. The methods that have been used in this project are: questionnaire survey to 133 municipalities that today are recycling food waste, telephone interviews with a number of biological treatment plants and innovators in the business, and Internet searching for relevant reports and studies in the field. The results show that the paper bag and the bioplastic bag both have shortcomings. Many of the shortcomings are related to the supplier/producer. Other problems such as misplaced waste, problems with mould, fly-maggots/flies etc. can be solved with information. Problems as corrosion on the collection vehicles and metallic substance in the plant have also been observed. A common problem when it comes to stores is how to best treat packaged material. Today there are treatment plants that treat certain packaged food waste, but a solution for glass is still missing. An issue which is not directly linked to the producer or the supplier is the issue of standardization of sorting equipment in kitchens. Many kitchens have own sorting equipment under the sink where the bags rarely fit. This leads to the bags being used in the wrong way. An important project would therefore be to gather the waste industry and kitchen suppliers to try to come up with a solution to this. There are a lot of technical problems in the process as arise when the biogas plant will digest the food waste as not are a homogenous material. The plants inquire for more effective technology for pretreatment the food waste and this could be a new research working. All that somehow affects the quality of digestate and compost are of interest to Waste Refinery, since quality issues are and will continue to be main issues within biological treatment

In this report municipalities, grid companies and electricity users' relations and responsibilities are discussed in connection to the actors experience during two storms named Per and Gudrun. Special focus is on households' action space, that is possibilities and constrains to uphold every day routines during outages. The material consists of case studies in Oestergoetland, involving a survey to households, interviews and participating observations. The theoretical perspective used is Karl Poppers' three worlds related to everyday life. World 1 is the physical and material world; World 2 consists of people's perception and ideas and World 3 is the cultural and social world. In world 1 is the importance of information and communication as well as spare power supply capacity discussed. Municipalities and grid companies emphasise Internet as an important communication tool. For the users the phone was the most important tool used during black-outs. One problem was however to get in contact with the energy company because of the overload on the companies' switchboard. Both the municipalities and the energy companies meant that they had enough spare power supply capacity. Around one third of the households said they had a portable generator to use during long lasting power outages. In relation to World 2 most households said that 12-24 hours power outages was acceptable, then the problems start for the households and they try to inform themselves of how long the outage will last. But some households never felt the need to contact anyone and they expressed a trust to the grid companies' competence to deal with the problems causing the outage. All actors state that the municipalities have a social responsibility to their citizens and must ensure that they do not suffer during outages. The grid companies' responsibilities according to the actors are to prevent power outages, repair damages and give the customers economical compensations. The households' responsibility for emergency management was fuzzier for the actors. Both municipalities and grid companies expected the customers to have some preparedness. The household meant that they lacked any responsibility to be prepared for an outage even if they need to be prepared to survive during the power loss. When it comes to economical compensation the grid companies meant that the compensation should cover the extra costs that the households had during an outage. The household thought that the compensation paid should cover the suffering that the households experienced due to not having electricity. On top of that the households felt they should have compensation for their expenses. World 3 consist of regulation and social networks. The networks between municipalities and grid companies differ. Some municipalities totally lacked cooperation and coordination with the grid companies, while others had established personal contacts and deep relations. Through the networks the municipalities could influence how the companies prioritize when they repaired the grid. The municipalities with well developed networks also had more knowledge and were better informed than municipalities lacking contacts. The households where not represented in any networks. The municipalities and companies instead developed different tools to inform the households such as Internet. The household used their networks consisting of neighbours and friends to be informed during black-outs. Neighbours' knowledge of each other is an important aspect of the emergency management in the rural areas. Municipalities' involvement in networks also influence if the municipality had priority lists or not. Municipalities engaged in networks with the energy companies had made priority lists. Municipalities without such involvement lacked priority lists and thought that it was not possible to make prioritizations between users

SCR at bio fuels combustion - phase 2. Measures to extend catalyst life time; SCR vid biobraensleeldning - etapp 2. Aatgaerder foer att foerlaenga katalysatorns livslaengd

In this project phase, the deactivation of catalysts during combustion of bio fuels, and different methods of regeneration have been investigated. The overall purpose is to improve the economic and technical possibilities to use SCR at bio fuels combustion. The two different methods for regeneration are washing with water and so called sulphation (treatment with sulphur dioxide). The results from wood fired FB-boilers show that the catalyst lose 25% (average) of the relative activity during a normal heat production season. The tendency is that a boiler with short residence time between final combustion and catalyst and/or high flame temperatures gives a faster deactivation. Such unfavourable conditions arise in FB-boilers with a large part of the combustion in freeboard/cyclone. The alkali content of the fuel (wood fuel) is of minor importance for the deactivation rate compared with the combustion conditions. The flue gas temperature within the interval 250 - 375 deg C is not an important parameter for the deactivation in the time interval 3 000 - 6 000 h. The 'new' honeycomb catalysts that were tested during phase two, BiotypA-C, evidently show different deactivation trends. The highly active BiotypC e.g. increases its activity during the first thousand hours. Calculations indicate that BiotypC at 315 deg C requires the smallest volume of catalyst over ten years of operation in order to maintain given performance. Practical consequences for downstream equipment also need to be carefully checked. Sulphation with SO{sub 2} works in the laboratory as a regeneration method for all of the tested samples. The sulphatised samples deactivation are almost comparable to a fresh sample when exposed to flue gas. About 80 % of the lost activity can be regained only by using sulphation. Plate-type catalysts gets a somewhat lower increase in activity compared to honeycomb-types, probably related to chemical rather than geometric design. High SO{sub 2}-concentration gives a quicker sulphation, but not a greater increase in activity after long time. The recommendation is to sulphatise with 500 ppm SO{sub 2} during at least 16 hours at high flue gas temperature. Since ammonium salts may give problems on downstream equipment (e.g. air preheaters) it is recommended that the ammonia dosage is closed during the sulphation. A simple model is presented for calculation of optimal procedure according to local conditions. The experiments with water washing show that the main part (65 - 80 %) of the potassium on the catalyst is washed out during 45 minutes in water. Also sulphur is washed out and must be replaced by sulphation. Some vanadium is lost (depending on type of catalyst) by washing in sulphuric acid, but not to a significant extent in water. The combination of water washing and sulphation gives about 75 - 120 % activity relative fresh samples depending on type of catalyst. Water washing combined with sulphation gives approximately 6 % higher activity at 300 deg C compared to sulphation alone, approximately 10% higher at 375 deg C (honeycomb {approx} 60% k/k{sub 0}). The advantage of washing increase by increased potassium content in the catalyst.

Research has been carried out concerning chemistry of nitrogen and sulfur oxides, with relevance to fluidized bed combustion. Studies of the heterogeneous decomposition reactions of NO and N{sub 2}O molecules have also been carried out. The effect of O{sub 2} on the heterogeneous reactions has been investigated and the results indicate that NO can deteriorate only in the reducing zones of a FBC. The formation of NO and N{sub 2}O as well as the question of what parameters affect this formation have been studied in a series of combustion experiments. In addition, it has also been demonstrated that the volatiles and the char are about equally important for the NO and N{sub 2}O formation. Quantum chemical calculations have been used to study the surface processes of the nitrogen oxides. Investigations of the desulfurization reactions at high percentages of CO{sub 2} with special regard to the PFBC technique have been made. In addition, the same reaction has been studied with e.g. spectroscopic methods at normal CO{sub 2} percentages, but with varying amounts of O{sub 2} and CO. CaSO{sub 3} has been demonstrated to be an intermediary and CaS as being one of the products. An important part of the project activities is the analytical work which primarily supports the full scale experiments on the 12 MW{sub th} CTH FBC boiler. As a link between the CTH boiler and our analytical laboratory, a chemical engineer also has been employed. In this activity is also included the development of sampling and analytical methods, e.g. NH{sub 3} and HCN sampling in the combustor. Time has also been allocated to measuring corrosive alkali metals (Na and K) in flue gases from a PFBC plant. 29 refs, 4 figs, 1 tab

Measurements of emissions during waste wood combustion to identify refurbishment needs; Maetning av emissioner vid foerbraenning av RT-flis foer att identifiera eventuella ombyggnadsaatgaerder

Energy Technology Data Exchange (ETDEWEB)

Lindau, Leif

2003-01-01

The background to this project is the new EU directive 2000/76/EG regarding incineration of waste. This directive may have an effect on emission limits for Swedish plants firing waste wood. It may lead to needs of refurbishment in e.g. the area of flue gas cleaning equipment. In order to produce a basis to evaluate the need for such upgrading, measurement of metals, HCI, SO{sub 2} , CO, TOC and dioxin have been carried out on three plants firing wood waste: a grate boiler (Handeloeverket P11), one circulating fluid bed boiler (Aaterbruket in Lomma), and a bubbling fluidised bed boiler (Johannes in Gaevle, firing 50% waste wood). The measurements have mainly been carried out after boiler, equivalent to upstream flue gas cleaning. The results are that the demands of the EU directive on most points can be managed with existing equipment if this consists of electrostatic precipitator or bag filter with good performance and flue gas condensor. Without flue gas condensor, there is a need for other measures for 1-10 and for grate boilers, SO{sub 2} as well. The requirements in the directive for TOC is weaker than the demand on CO, and correspondingly, the demand on CO is driving. The level of dioxin from the boiler (upstream filter) exceeds allowed emission, and is in the range of 0,1-2 ng TE/Nm{sup 3} tg, 6 % O{sub 2} . Existing equipment will meet the emission limit for the lower levels (0,1-0,3) , but not safely for the higher levels (1,5-2). Correspondingly, there may be a need for equipment upgrading, e.g. in the form of activated carbon injection upstream flue gas filter.
