The Use of the Veterinary Technician in Bovine Practice
Creators: name: Harrington, Ben D.
Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 1978

description: As a lot of you know, there is a kind of controversy within our profession now on the use of animal technicians. North Carolina developed an animal technician school early and the first graduates were in 1962. I first became involved with the A VMA's committee for animal technicians' activities and training and served on that committee from its inception in 1972 to about 1976. Since 1976 I have been on the council of education and serve on that at present as chairman of non-professional assistants for veterinarians. There are several aspects we could look at.

Identification and decentralized control of a dual-actuator hard disk drive system
Creators: name: Zheng, Jinchuan

Publisher: name: Swinburne
Year: 2024

description: The dual-actuator hard disk drive with two voice coil motor actuators mounted in the diagonal corners of the baseplate allows faster data access with relatively slow spindle speed. However, the mechanical interaction between the actuators tends to affect the head positioning accuracy. In this paper, we use the circle-fit modal testing method to identify the dual-input dual-output frequency response model of the dual-actuator plant. We discuss the decentralized control scheme for the dual-actuator tracking servo. The servo loop decomposition reveals that the interaction induces narrow-band vibrations near the crossover frequency. We propose a phase-lead interaction filter with a slight change to the loop stability to suppress the vibrations. Experimental results on a dual-actuator prototype show that the position error signal 6 σ value due to interaction vibrations is reduced by 61% with the interaction filter in combination with the decentralized control scheme.
The role of cholinergic interneurons in regulating corticostriatal culture response to dopaminergic stimulation

Year: 2011
Subjects: subject: Biology, Neuroscience.

description: Introduction: We investigated the cholinergic regulation of striatal response to dopaminergic stimulation. Methods: Rat neurons for dissociated striatal cultures were harvested from E18.5. E14.5 neurons were supplemented to the cultures to provide cholinergic interneurons. Cultures were stimulated with dopamine D1R or D2R agonist and antagonist and changes in c-FOS and EGR-1 expression and DARPP-32 phosphorylation were assessed by Western blots. Electrophysiological recordings were performed using multielectrode array. Results: Molecular studies: Although no significant changes were observed, trends showed that cholinergic innervation produced a differential regulation of c-FOS and EGR-1 expression associated with D1R and D2R signaling. Electrophysiological analysis: Significantly more activity was detected in cultures without cholinergic interneurons. Moreover, an increase in firing was seen in cultures with cholinergic interneurons following the addition of a muscarinic 1 receptor antagonist. Conclusion: Our results suggest a differential impact of cholinergic regulation on D1R and D2R signaling pathways.
La relation drogue-criminalité dans une justification pour une politique en matière de drogues

description: La présente thèse porte sur l'examen des arguments drogue-criminalité employés par une gamme d'acteurs sociaux qui ont témoigne et/ou déposé un mémoire/document ou encore procédé à la rédaction des rapports produits aux récents Comité spécial du Sénat sur les drogues illicites et Comité spécial sur la consommation non médicale de drogues ou médicaments de la Chambre des communes, afin de soutenir une prise de position sur la politique à suivre en matière de drogues. S'agissant d'une analyse documentaire, un échantillon de 52 interlocuteurs oraux et/ou écrits a été constitué, interlocuteurs provenant de six milieux, soit les milieux gouvernementaux, les milieux policiers, les milieux de l'intervention, la communauté scientifique, les mouvements militants et le grand public. L'analyse de cette imposante documentation nous a permis de constater que selon les discours drogue-criminalité employés, les données sur lesquelles ces discours s'appuient et les intérêts personnels, collectifs et corporatistes enjeu, les interlocuteurs seront tentés d'adopter une approche antiprohibitionniste ou, à l'autre extrême, une approche plus ou moins prohibitive et répressive s'inscrivant dans le prohibitionnisme qui a actuellement cours en matière de drogues, au Canada.
Vers la liberté: Le façonnement de soi dans l'oeuvre de Hegel

description: Cette thèse se veut une exploration de la Bildung (culture et éducation) entendue comme processus de formation individuelle dans l'oeuvre de Hegel. Centrale à l'étude est l'idée selon laquelle il n'y a de liberté sans libération s'effectuant dans et à travers le mouvement de la culture au cours de la vie de l'individu. Nous avons tenté de systématiser la Bildung afin de montrer comment cette dernière s'articule à l'intérieur des institutions du monde moderne, à savoir de la Sittlichkeit. Il s'agit ici du passage de la première nature à la seconde dans le développement anthropologique et du passage de la seconde nature à la seconde nature spirituelle dans le développement phénoménologique. Le premier moment de la culture s'effectue par l'habitude au sein de l'unité familiale et le second se manifeste dans le dépassement de l'aliénation théorique et pratique dans l'école et les institutions de la société civile et de l'État.
Expression and localization of SLC9A2 and SLC9A3 sodium hydrogen exchangers and their possible role in acid-base regulation in freshwater rainbow trout (Oncorhynchus mykiss)

description: Teleost fish, like other vertebrates, maintain blood pH at a constant value, with the gills and kidney being major sites of regulation. This thesis examines the involvement of two members of the Na+/H + exchange (NHE) gene family, NHE2 and NHE3 in branchial and renal acid-base regulation in freshwater rainbow trout (Oncorhynchus mykiss ). Using homology cloning techniques and mining of genomic databases, genes orthologous to NHE2 (trout NHE2) and NHE3 (trout NHE3a and NHE3b) were described and characterized. Applying a variety of techniques including immunocytochemistry, in situ hybridization, Western blotting and real-time PCR, I demonstrated that NHE2 and NHE3 are the predominant gill and kidney isoforms, respectively. In the gill, NHE2 and NHE3 are expressed in a subset of mitochondria rich cells (MRCs) termed PNA+ (peanut lectin agglutinin) MRCs. NHE2 mRNA levels were significantly increased during ambient hypercapnia, responses that may have been linked to elevated levels of plasma cortisol. In the kidney, NHE3 appeared to be localized to the apical membrane of proximal tubule cells where it is presumed to play an important role in HCO3- reabsorption. In support of its role in HCO3- reabsorption, renal NHE3 mRNA expression and protein levels were significantly increased during hypercapnia, responses that may have been cued by elevated plasma cortisol.

description: The 19th century in Colombia is a particularly fruitful period to analyze the work of translators. At a time marked by the emergence of Nation-States, and consequently, by the search of models to be followed in almost every area. The figure of poet and translator Rafael Pombo (1833-1912) emerges. In this case-study we will analyze how this context affected the translations he produced. Based on the analysis of his translations of canonical authors and classical fables and child stories, as well as paratextual and parallel sources, this study will show how Rafael Pombo became an "intercultural mediator" at a time when the "Americas" met each other. Furthermore, in Pombo's work we can explore several translations functions, particularly a pedagogical function. This research will show that through the discovery of the relation between contexts, the translation, and his translations, and by articulating the translator's motivations and conception of translation, we can trace a general survey of translation and translation history can become a tool to account for translation practices at a particular time.
Vapour-liquid equilibria in the systems carbon tetrachloride-toluene and n-pentane-benzene.

Subjects: subject: Engineering, Chemical.

description: A modified recirculation Dvorak and Boublik still was used in the equilibrium determination. The vapour-liquid equilibria in the systems carbon tetrachloride-toluene were studied at five isothermal conditions. Liquid activity coefficients were evaluated. The values of gamma were close to unity. The vapour-liquid equilibria in the systems n-pentane-benzene were studied at four isothermal conditions. Liquid activity coefficients were also evaluated. Liquid-vapour equilibria at isobaric conditions were correlated using the data of heat of mixing at 25°C and the experimental ln gamma values obtained from this work. The In gamma values were correlated by means of the three-constant Redlich-Kister equation for the binary systems.

description: Primary agricultural-markets may be prone to large seasonal price drops when certain constraints inhibit farmer-sellers from behaving as rational economic agents. As several Asian countries are reeling under acute agrarian distress, this study focuses on India to conduct disaggregated univariate time-series analysis on the seasonal component of four major agricultural commodity prices in over 300 wholesale markets (mandis) using monthly data spanning more than a decade (2003-2016). Adapting from recent contributions made to seasonality estimation in short samples, the study tests harvest-pattern based specifications of seasonality (viz. trigonometric and saw-tooth functions) against an unrestricted dummy-variable specification to reduce estimation bias. Empirical results show considerable variation in magnitudes of seasonal price gaps (SG) across space and commodity. In several cases, they are higher than in international prices. A cross-sectional analysis of the estimated SGs over socio-economic indicators reveals that seasonal price drops have a direct relationship with the proportion of smallholders in a district. This has adverse implications for inequality and welfare. Furthermore, SGs are lower in the districts which have relatively higher access to credit. The work concludes that effective delivery of policy necessitates location-specific approaches. Continuing with blanket policy responses to the agrarian crisis may aggravate existing inequalities.

description: In summary, to realize the full potential of any diagnostic laboratory: Establish a meaningful liaison with the laboratory: learn what services they provide, what are their limitations, and find out who you can talk to, on a professional basis, to discuss mutual requirements and desires. Submit appropriate samples in good condition from representative cases. Submit a complete and accurate history. Carefully evaluate laboratory findings and correlate them with your clinical findings to arrive at a final diagnosis.

Conjugated and unconjugated estrogens in the fetal and maternal fluids of the pregnant ewe: A possible role for estrone sulphate in placental attachment.
Creators: name: Carnegie, Jacqueline Anne.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1977
Subjects: subject: Agriculture, Animal Pathology.

description: Estrogens (estrone sulphate, estrone, estradiol-17beta sulphate and estradiol-17beta) were measured in the allantoic and amniotic fluids and the maternal peripheral, uterine venous and ovarian venous plasma of the ewe throughout gestation. Particular emphasis was placed on the interval day 20 to day 60 of gestation since the estrogen profile in the various fluid compartments of the pregnant ewe during the time of the implantation of the fetus into the uterus of the mother was of primary interest in this study. Estrone sulphate was the most important estrogen with respect to concentration present. It could first be measured in the allantoic and amniotic fluids at day 31 and peaked between days 45 and 50 of pregnancy. It was found that the changes in levels of estrone sulphate, estrone and estradiol-17beta sulphate in the allantoic fluid throughout gestation were very similar to what has been reported regarding estrone sulphate in the peripheral plasma of the pregnant pig, in the allantoic fluid of the cow and regarding total estrogens in the urine of the pregnant pig. A comparison of the estrogen levels in the uterine venous, ovarian venous and maternal peripheral plasma of the pregnant ewe implicated the conceptus, rather than the ovaries, as the source of these estrogens produced during gestation. The possible site or sites of production of these estrogens within the conceptus were discussed along with theories regarding where the conversion of the estrogens to active estradiol-17beta might take place. A functional relationship between estrogens and placental vascular development is postulated.

description: Triggered by growing societal demand, various labels and program target at improving animal welfare in intense livestock farming. Based on the assumption of a trade-off between farms’ economic performance and animal welfare, these program typically compensate farmers for potential losses from adjusted husbandry conditions such as additional space. Yet the complexity of animal welfare challenges its unique measurement and consequently the evaluation of such measures, casting doubt on the effectiveness of these program. Therefore, we first target at improving the understanding of the relation between animal health, as a core dimension of animal welfare, and farm performance from an empirical perspective, and second to evaluate the German program “Initiative Tierwohl” (ITW). We rely on bookkeeping data for 483 pig fattening farms including detailed animal health indicators collected at the abattoir. To test for the potential trade-off, we use relative farm performance measures identified from non-parametric data envelopment analysis. Our results do not support a trade-off between animal health and farm performance, but rather indicate the possibility for high productivity at comparatively high levels of animal health. Further, we find participants to perform slightly better in both dimensions, supporting the label’s claim of improved animal welfare.
Practical Applications of Embryo Transplanting

description: The embryo transfer program is a utilizable management tool which recently became available to the dedicated seeds tock breeder. In my opinion the success or failure of embryo transplant revolves around him. We have always had a good supply of these people around and embryo transplant has been around for at least two decades. Then how come it was only developed within this decade? The reason is simple. There was not sufficient interest to fund it until the new breeds were introduced into North America ten years ago. New Breeds, Inc.'s experience reveals that embryo transplanting is a good, practical management tool when coupled with good animal husbandry, shrewd merchandising, acceptable phenotype, and superior genetics.

Long-Term Calcium-Phosphorus Studies in Confined Dairy Cows
Creators: name: Ward, George
name: Call, E. P.
Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 1978

description: Calcium balance can be kept near even or positive in early lactation if calcium and phosphorus intakes and vitamin D consumption are adequate. Adequate calcium consumption promotes more rapid uterine involution and earlier ovulation. Phosphorus consumption must be adequate from day to day. There is no phosphorus-sensitive mechanism to elicit phosphorus resorption from bone. That mechanism is only calcium-sensitive. Inadequate phosphorus intake depresses appetite as well as preventing bone accretion. Phosphorus balance, with adequate phosphorus intake, largely depends on calcium adequacy since the calcium-tophosphorus ratio in bone is constant. Our study comparing monosodium phosphate with calcium phosphate as supplements for an alfalfa hay and sorghum grain ration may have shown a chlorine deficiency. Salt was omitted from the grain but was available ad libitum. Very little salt consumption was the unique characteristic associated with the sodium phosphate treatment. Elevated chine, slab-sidedness, and tucking up in the flank were noted in the cows which ate little salt. Salt appetite appears to be sodium-sensitive.

Genetics and Disease in Cattle
Creators: name: Leipold, H. W.
Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 1978

description: There are many bovine congenital defects of unknown etiology, suspected etiology and known etiology. Congenital defects of known environmental etiology such as bovine virus diarrhea-induced cerebellar atrophy, or plant-induced deformity such as crooked-calf diseases caused by lupine, require changes in management procedures. Defects caused by genetic factors are of considerable concern to the AI stations, cattle breeders, and cattle breed associations. Initial diagnosis of congenital defects is frequently required of practicing veterinarians. Some of the genetic diseases of current concern to the cattle industry of the United States include congenital defects of the skin such as epitheliogenesis imperfecta, hypotrichosis, fragile skin, and protoporphyria. Of the internal organs, the reproductive system is of particular concern. Defects of bone are numerous and may affect single structures such as adactyly, tibial hemimelia, and syndactyly. Generalized skeletal defects of importance include dwarfism and osteopetrosis. Muscular defects of significance are doublemuscling and arthrogryposis. Furthermore, genetically-caused defects of the central nervous system need further attention, particularly internal hydrocephalus and mannosidosis. Many defects encountered of suspected etiology need close attention. In this category, as well as those of unknown etiology, practicing veterinarians remain the main source of information to guide further study.

description: The Cariceae (Carex & Kobresia; Cyperaceae) account for ca. 10% of Canada's native vascular plants, yet diversity within the tribe is overlooked due to its taxonomically-difficult floral morphology. DNA barcoding is a useful tool for identifying animals and the technique is currently being adapted for use in plants. This thesis develops a reference barcode database for the Cariceae of North America, north of Mexico, using the chloroplast gene matK. A species resolution rate of 39% is reported, although when broken down into political regions, this can increase to 75%. Unknown tissue samples from across North America were then identified using this reference database; 50% of these were identified to a single species matching the morphological identification, and 50% were identified to a group of taxa containing the correct identification. An ecogeographical regional database for the Arctic Archipelago was also challenged with 230 unknown samples and identified 98% to a single species.
Femmes vivant avec le VIHsida et lipodystrophie: Étude du processus de transformations corporelles

description: À l'instar de la majorité des pays à revenu élevé, le Canada dispose, depuis 1996, de régimes pharmacologiques pour traiter les personnes vivant avec le VIH/SIDA. Parmi les réactions néfastes de la thérapie antirétrovirale, le syndrome de la lipodystrophie est une condition débilitante qui afflige les personnes vivant avec le VIH/sida et ce, tant sur le plan physique que psychosocial. Conscient de l'ampleur de cette problèmatique qui, à ce jour, ne semble pas avoir été étudiée en contexte québécois, cette recherche qualitative décrit le processus de transformations corporelles auquel font face les femmes atteintes de lipodystrophie et explore les répercussions psychosociales de cette condition qui se manifeste progressivement au cours du traitement. Un devis de recherche qualitatif, de type descriptif et exploratoire, convenait tout à fait aux objectifs de cette recherche. Compte tenu de la problématique de recherche et des objectifs de recherche, la théorisation ancrée a été privilégiée pour orienter ce projet au plan methodologique. La collecte des données s'est deroulée sur une période de 3 mois et a été réalisée par le biais d'entrevues semi-dirigées avec 19 femmes vivant avec le VIH/SIDA. En résumé, les résultats de recherche indiquent que le processus de transformations corporelles engendre une profonde détresse chez les femmes vivant avec le VIH/SIDA. Les résultats de l'étude montrent, d'une part, la détresse (physique et mentale) engendrée par le corps lipodystophie et attestent, d'autre part, des relations de pouvoir avec le complexe médico-pharmaceutique. Au terme de cette recherche les résultats montrent que: le corps est un objet de pouvoir au coeur de ce complexe; que les tensions relatives au traitement amplifient la détresse des femmes vivant avec le VIH/SIDA; que la visibilité du corps entraîne la stigmatisation des femmes vivant avec le VIH/SIDA; et que la lipodystrophie n'est pas la transformation banale de caractéristiques physiques, mais plutôt la reconfiguration définitive de la personne en entier.
Exploiting differential endogenous microRNA expression to enhance oncolytic vesicular stomatitis virus tumour tropism
Creators: name: Edge, Robert E
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2010
Subjects: subject: Chemistry, Biochemistry.

description: The creation of potent oncolytic viruses (OVs) suitable for the clinic may require new strategies in virus design. Replication-competent viruses facilitate a variety of approaches to achieving tumor specificity. Altered expression of microRNAs is a common hallmark of cancer that this thesis demonstrates can be used to alter expression of a potent wild-type viral gene to achieve tumor-specific replication of an engineered vesicular stomatitis virus (VSV). Incorporation of microRNA complementary sequences (miRTs) within VSV causes reduced accumulation of miRT containing mRNAs. Let-7 miRTs introduced into the 3' untranslated region (3'UTR) of VSV matrix protein mRNA eliminate undesirable replication and associated toxicity in normal cells but permit growth in cancer cells both in vitro and in vivo . Similarly the incorporation of mir34a miRTs results in reduced in vitro VSV replication and cytotoxicity in the presence of activated p53. This thesis provides proof of concept that viruses designed to exploit the differential microRNA expression in cancer cells is a viable approach, potentially useful in optimizing oncolytic viral gene expression for maximal antitumor activity and safety.

La responsabilité pour le défaut de sécurité des biens: De l'importance de différencier les fondements de la garantie de qualité de ceux de l'obligation de sécurité

Year: 2004

description: Quand on analyse les règles applicables en matière de responsabilité du fabricant pour les biens non sécuritaires causant des dommages corporels ou matériels, l'impression qui ressort en est une de grande complexité. Ce domaine du droit est caracterisé par un manque de cohérence et une grande confusion dans la façon d'appliquer les dispositions législatives en la matière. En effet, bien que le Code civil du Québec prévoit maintenant un régime spécifique applicable pour sanctionner les dommages causes par les biens dangereux que l'on retrouve en matière extracontractuelle aux article 1468, 1469 et 1473 C.c.Q., la doctrine se refuse à appliquer ces dispositions lorsque le dommage survient dans le cadre contractuel en raison principalement de la règles de l'interdiction de l'option de régime. Les auteurs appliquent donc la garantie de qualité pour sanctionner ces dommages causes par un bien dangereux lorsqu'il survient dans le cadre de la vente. Par conséquent, ils considèrent que cette obligation est suffisamment flexible pour inclure la sécurité. Or, cette interprétation cause de nombreuses difficultés puisque la garantie de qualité se voit investie d'un rôle sécuritaire qui la dénaturé et ne lui convient guère. En effet, la sécurité n'est pas de l'essence de la garantie puisque cette dernière est prévue pour sanctionner le vice caché compromettant l'utilité du bien. Dès lors, une meilleure délimitation des domaines respectifs propres à la garantie de qualité et à l'obligation de sécurité s'impose en vue de soustraire l'obligation de sécurité du domaine contractuel de la garantie de qualité. Ce faisant, l'obligation de sécurité ainsi affranchie du cadre contractuel devient forcement extracontractuelle et a vocation à s'appliquer à l'égard de tous.

Subjects: subject: Engineering, Electronics and Electrical.

description: This thesis develops a model for severe all-terrain vehicle (ATV) injuries using artificial neural networks (ANNs) with data from the Canadian Hospitals Injury Reporting and Prevention Program (CHIRPP) and analyzes the model to find the contribution of each factor in predicting severe injury. From the analysis of the model, recommendations are made on the factors that should be investigated further to reduce severe injuries. An analysis of ANN architecture shows that a configuration with no hidden nodes or layers results in optimal performance. The performance results of the ANN gives a logarithmic-sensitivity index of 0.09, sensitivity of 44%, specificity of 84%, correct classification rate (CCR) of 70% and receiver operating curve (ROC) area of 0.72. The most important input factors for predicting severe injury are: nature of injury, helmet, age group, mechanism, seat position, circumstances of collapse, body part and sex.

description: The deposition of an atomically precise nanocluster, for example, Ag44(SR)30, onto a large‐band‐gap semiconductor such as TiO2 allows a clear interface to be obtained to study charge transfer at the interface. Changing the light source from visible light to simulated sunlight led to a three orders of magnitude enhancement in the photocatalytic H2 generation, with the H2 production rate reaching 7.4 mmol h−1 gcatalyst−1. This is five times higher than that of TiO2 modified with Ag nanoparticles and even comparable to that of TiO2 modified with Pt nanoparticles under similar conditions. Energy band alignment and transient absorption spectroscopy reveal that the role of the metal clusters is different from that of both organometallic complexes and plasmonic nanoparticles: A type II heterojunction charge‐transfer route is achieved under UV/Vis irradiation, with the cluster serving as a small‐band‐gap semiconductor. This results in the clusters acting as co‐catalysts rather than merely photosensitizers.
Apocalyptic and Sethian trajectories and Melchizedek speculations in late antique Egypt: The "Melchizedek Apocalypse" from Nag Hammadi (NHC IX, 1) as a test case
Creators: name: Parton, Elizabeth A

Subjects: subject: Religion, General.

description: The Melchizedek Apocalypse is a Coptic text, written in the late second or early third century CE, by a Sethian gnostic author, and discovered near Nag Hammadi in Egypt. Only one extant copy of the document has survived, preserved in the translation of the original Greek, in Codex IX of the Nag Hammadi collection. Melchizedek has significant codicological issues, with only 19 of the approximately 745 lines of the original document completely extant, and even with a great deal of effort and scholarly conjecture, only about 47% of the text is at all recoverable. Perhaps because of the state of the manuscript itself, the Melchizedek Apocalypse has been examined by only a few scholars, those tasked with the production of the critical editions, translations and commentaries on the text, Birger A. Pearson (English), Hans-Martin Schenke (German), Wolf-Peter Funk, Jean-Pierre Mahe (French), and Claudio Gianotto (French and Italian), in particular. The text presents Melchizedek, the king of Salem and priest of God Most High first seen in Genesis (14.18--20), as an apocalyptic and gnostic hero, assuming the authority of the character in order to present an understanding of the cosmos, reflective of both literary styles and their visions of this world and the next. The text is demonstrative of apocalyptic and gnostic conventions, as well as of the literary traditions surrounding Melchizedek speculation, and socio-historical elements having to do with its Egyptian milieu. In the present work I examine each of these designations on the way to establishing the literary and historical contexts of the text. Following the trajectory theory suggested by James M. Robinson and Helmut Koester, through the examination of the Melchizedek Apocalypse and its literary and historical contexts I will place it within the various trajectories of Judaism, early Christianity and Sethian gnosticism, seeking to demonstrate the over-lapping nature of the literary and religious distinctions of the early centuries of the Common Era. In order to do so, I address the difficult issue of "gnosticism" as a viable categorization, beginning with the arguments of Michael A. Williams, Karen L. King and Carl B. Smith. As Melchizedek can be seen as a clear example of the diversity of forms within the religious traditions of Egypt in late antiquity, it acts as an ideal test case.

The ultrastructure of the flagellar apparatus has been described from several dinoflagellates in the last few decades, and the basic components appear to be well conserved. The typical dinoflagellate apparatus is composed of two basal bodies surrounded by striated collars attached to a connective fiber. The longitudinal basal body is connected to a longitudinal microtubular root (LMR; equivalent of R1) and single microtubular root (R2), whereas the transverse basal body is connected to a transverse microtubular root (TMR; R3) and transverse striated root (TSR) with a microtubule (R4). Some of these components, especially the connective fibers and collars, are dinoflagellate specific characteristics that make their flagellar apparatus relatively complex. We also compare these structures with the flagellar apparatus from a number of close relatives of dinoflagellates and their sister, the apicomplexans, including colpodellids, perkinsids, and Psammosa. Though the ultrastructural knowledge of these lineages is still relatively modest, it provides us with an interesting viewpoint of the character evolution of the flagellar apparatus among those lineages.

description: Global change is expected to accelerate extinction rates substantially. Accurately predicting species responses to future climate and land use changes and the conservation effectiveness of protected areas are critical. Here, I test whether species distribution models can predict how species' ranges shift through time and if protected areas are more robust to recent global change impacts than areas lacking formal protection. Purely spatial species distribution models are able to predict how species' distributions have changed over the 20th century for many species. However, because this predictive ability was not strongly related to biological or sampling characteristics considered here, there is no a priori way to determine which species' models will accurately predict range shifts through time. Protected areas rarely performed differently than randomly selected, unprotected areas in terms of species richness change and species composition change over the past century. Conservation strategies should focus on improving landscape connectivity to facilitate species' geographical responses to future global changes and should account for uncertainty in predictions of those responses.

Uncanny encounters: on writing, anxiety and jouissance
Creators: name: Hecq, Dominique

description: In this paper, I'd like to investigate the relationship between writing as symptom, anxiety and jouissance, or more particularly, between writing as sinthome (a particular form of the symptom as suppliance), anxiety, and two forms of jouissances: phallic jouissance and the jouissance of the Other. I hope to be able to suggest that anxiety is the organizing principle of the jouissance of the writer---for as an affect transmuted into writing, anxiety contributes to creating another sense beyond its signification, which means that a supplementary jouissance invades the scene of writing. Thus, although neither writing nor anxiety are symptoms as such, anxiety organizes the writing process in a way that 'harmonizes with castration' (Lacan, 15-01-1974) hence making it into a particular type of symptom.
A Progressively Reliable Image Transport Protocol over Wireless Sensor Networks

description: Images are extensively used in Wireless Multimedia Sensor Networks (WMSN) for surveillance and object monitoring. The transmission of image data constitutes a significant portion of network bandwidth. Given the inherent differences of Wireless Sensor Networks (WSN) from wired networks, such as high probability of non-congestion related packet loss, very low bandwidth, Quality of Service (QoS) requirements, and limited processing power, the traditional transport protocol---the Transmission Control Protocol (TCP)---is not suitable for transferring images over WSN. In this thesis, a Progressively Reliable Image Transport Protocol---PITP, is proposed. First, with the support of progressive JPEG and out-of-order delivery of packets, this new protocol can display images smoothly with incremental quality. Second, this protocol guarantees receiver-controlled reliability and sound congestion control. In addition, a synchronization control mechanism is proposed within the protocol. A series of experiments are designed and simulated with ns2 to evaluate the performance of PITP. According to the results, PITP is proved to be suitable for image transmission over WSN.
A compliance framework for business processes based on URN

description: Compliance with institutional policies, government regulations and applicable legislation is a major concern for any organization when defining its business processes. These regulations are usually complex, hard to understand, and they rarely come with a model or taxonomy. As well, both business processes and regulations are susceptible to change with the potential of introducing non-compliance. This thesis presents a framework that intends to help companies track compliance by leveraging requirements engineering models. Compliance is managed by establishing links between User Requirements Notation (URN) models of government legislation and organizational business process and tracking how they are affected in a requirements management system. Special attention is paid to maintaining compliance as either the legislation or business processes evolve over time. The framework is evaluated by way of a case study from the healthcare industry. The case study centres on the approval process implemented to control access to a data warehouse at a major Ontario hospital and whether or not this process complies with relevant legislation and hospital guidelines. The relevant legislation in Ontario is the new provincial Personal Health Information Privacy Act (PHIPA).

Can a Click be a Word?: Infants’ Learning of Non-Native Words

description: Forms that are non-linguistic markers in one language (i.e. ‘tsk-tsk’ in English) may be part of the phoneme inventory and carry meaning in another language. In the current paper, we demonstrate that infants’ ability to learn words containing unfamiliar language sounds is influenced by the age and linguistic sophistication of the infant learner, as well as by cues to a speaker’s referential intent. At 14 months, infants learned words with non-native speech sounds, but only when referential cues were available. At 20 months, infants with larger vocabularies failed to learn the same words even in the presence of referential indicators, while those with smaller vocabularies succeeded. The implications of the relation between linguistic sophistication and non-native word learning are discussed.
BioExcel Webinar #33 - COMPSs: a high level framework for the development of parallel applications
Creators: name: Lezzi, Daniele

description: One of the biggest challenges in the programming of scientific application is the efficient exploitation of computing infrastructures. In the era of Big Data applications one of the pressing requirements on the researcher is to achieve a convergence between the Exascale and Big Data worlds. The issues related to such a challenge include the design of tools to easily program or migrate the code and to execute the applications on the computing infrastructures. Amongst the different paradigms for implementing distributed applications, the task-based programming has proven to be a suitable model. PyCOMPSs/COMPSs is a task-based framework which aims to ease the development and execution of applications for distributed infrastructures, such as Clusters and Clouds. A COMPSs application is composed of tasks, which are annotated methods. At execution time, the runtime builds a task graph that takes into account the data dependencies between tasks, and from this graph schedules and executes the tasks in the distributed infrastructure, exploiting the inherent parallelism and taking also care of the required data transfers between nodes. COMPSs is written in Java, and supports applications in Java, Python and C/C++. COMPSs has proven to improve the performance of the execution of the applications, achieving scalability while maintaining an easy programming model. COMPSs has been adopted by several user communities from different fields such as Life Science, Earth Science, Engineering belonging. It is daily used by BSC and RES users in Marenostrum and is also deployed in worldwide infrastructures such as the EGI Federated Cloud. In this webinar we will introduce COMPSs fundamentals and we will present the approach in the BioExcel CoE to develop life science workflows composed of reusable building blocks developed with PyCOMPSs.
