Epimorphosis of Heterosymelic Appendages inTegenaria Atrica(Araneae, Agelenidae)

Studies of epimorphic regeneration of appendages were carried out on larvae and nymphs ofTegenaria atricaC.L. Koch with heterosymely (accretion of appendages on the same side of the body) of two walking appendages and of walking appendages with pedipalpi. All the anomalies were obtained by exposing developing embryos to alternate temperatures of 14 and 32°C. Amputation of fragments of anomalous appendages was always followed by regeneration. Based on the characteristic external structures of the regenerating joints, successive stages of epimorphosis were estabilished, whose start and end were marked by ecdyses. Several types of regenerates were found, whose anatomical structure did not undergo further significant changes until the end of our observations.

Authors: Żołnierczyk Jolanta Dominika , Kiliańska Zofia Maria
Published: March 2011

Programmed cell death (apoptosis) plays a vital role in the regulation of cellular homeostasis. Because of apoptosis fundamental importance, this process is highly regulated. One important set of factors involved in apoptosis regulation is the Bcl-2 family proteins. Bcl-2 family members form a complex regulatory network that controls cell survival and death in response to different physiological and pathological signals. This family includes both pro- and anti-apoptotic members, and Bax protein (Mol wt 21 kDa) is a major pro-apoptotic factor with multifunctional activity. This review summarizes new data about the main representative of Bcl-2 family – Bax, its structure and mechanism(s) by which this protein modulates apoptosis.
Physiopathological Implications of 7TM Receptors
Authors: Cygankiewicz Adam I.
Published: March 2011

Seven-transmembrane (7TM) receptors are one of the most important proteins involved in perception of extracellular stimuli and regulation of variety of intracellular signaling pathways. Divergence of receptor types, their ligands and signaling pathways makes 7TM receptors important factors in pathology of many diseases. This review focused on the main diseases in which involvement of 7TM receptors was established e.g., retinitis pigmentosa, severe obesity, and dwarfism. Recent findings of aberrant expression of 7TM receptors in development of cancer were also summarized.

Seasonal Characterisation and Trends Study of Nutrient Concentrations in Surface Water from Catchments with Intensive Livestock Farming

Temporal changes in observed nitrogen and phosphorus losses to surface water were studied in 3 agricultural catchments in order to evaluate the achievement of water protection targets in Latvia. The aim of this study is to investigate the water quality measures in high density livestock farming catchments. Long-term monitoring data (years 1996-2008) of water quality used in the analysis show a high annual and monthly variability of nutrients. The results demonstrate little or no reduction of nutrient concentrations in surface water. The results suggest that water protection measures for agricultural production need to be further intensified.

Simulation of the Stock of Electric Appliances and Calculation of Standby Losses for Latvia

Standby losses in households are discussed in this paper. As there was no information on the total volume of standby losses in Latvia, the objective of the study was to calculate: the percentage from the household total electricity bill that goes to standby losses; what are the total costs for these losses; and how much CO2 is produced to generate the amount of electricity that is needed to cover these standby losses. All calculations were conducted for one and for all households in Latvia and the results of one household were compared with an average European household. Finally, the savings potential that can be obtained implementing the Eco-design Directive and other political instruments was examined.

Hemp (Cannabis sativa L.) as an Environmentally Friendly Energyplant

Hemp is suitable as a renewable energy resource. The aim of this study was to clarify local hemp's (Cannabis sativa L.) possibilities for energy use. Arsenic (As), cadmium (Cd), lead (Pb) and titanium (Ti) presence in hemp was determined using an inductively coupled plasma optical emission spectrometer Optima 2100 DV. If there were increased N fertilizer rates, there were increased hemp ‘Pūriņi’ seeds and shive yield increases, but the oil content was reduced. Arsenic content was higher in the shives than in the stems with fibre. The ash content depends on non-organic substances which the plants absorb during the vegetation season. The lignin content depends on several factors: plant parts, and the N fertilizer rate. The unexplored factors have a great effect on the ash and lignin content. Hemp is suitable for cultivation and for bio-energy production in the agro-climatic conditions in Latvia.

Modeling of the Thermodynamic Properties of Liquid Fe-Ni and Fe-Co Alloys From the Surface Tension Data

Recently proposed method of modeling of thermodynamic properties of liquid binary alloys from their surface tension data is described. The method utilizes Melford and Hoar equation, relating surface tension with excess Gibbs free energy, combined with new description of the monatomic surface layer and β parameter. The method is tested on Fe-Ni and Fe-Co alloys and the obtained results show very good agreement with experimental thermodynamic data of other authors. The model allows also to calculate the surface tension from thermodynamic data, and it gives better agreement with experimental results than those modeled with the use of Butler equation and traditionally defined monatomic surface layer and β = 0.83.

Biological activity of the red algaLaurencia brandenii

The marine red algaLaurencia brandeniicollected from the southwest coast of India (Indian Ocean) was extracted and fractioned using column chromatography. The individual fractions were evaluatedin vitrovia antimicrobial activity against six species of Microbial Type Culture Collection and three species of clinical human pathogens, antipest activity onSitophilus oryzae, maggoticidal activity against 2ndinstar larvae ofSarcophagasp. and termiticidal activity againstMicrotermes obesi.It was found that the fraction eluted using petroleum ether:chloroform (6:4) exhibited broader biological activities. The phyco-constituents of the active fraction were identified by gas chromatography-mass spectrometry (GC-MS) analysis. The GC-MS profile of the active fraction revealed that the main constituent was octadecadienoic acid (49.75%) followed by n-hexadecanoic acid (14.24%), which might have a functional role in the biological activities. The overall activity profile envisages that these bioactive compounds fromL. brandeniicould be utilized as a renewable natural resource for the development of novel environmental-compatible formulations for the control of human pathogens, pests, termites and maggots.

Preliminary Ecotoxicity and Biodegradability Assessment of Metalworking Fluids

The main aim of this study was to evaluate the potential of activated sludge from sewage treatment plant to degrade selected MWFs (ecotoxicity to bacterial consortium) and to evaluate the ecotoxicity by Lemna minor-higher plant. After evaluating the ecotoxicity, biodegradations rate with activated sludge was assessed on the basis of COD measurement. Preliminary study of measuring the ecotoxicity according to OECD 221 by Lemna minor shows effective concentration of Emulzin H at the rate of 81.6 mg l-1, for Ecocool 82.9 mg l-1, for BC 25 about 99.3 mg l-1, and for Dasnobor about 97.3 mg l-1. Preliminary study of measuring the ecotoxicity by bacterial consortium according to OECD 209 (STN EN ISO 8192) shows effective concentration of Blasocut BC 25 at the rate 227.4 mg l-1. According to OECD 302B, the biodegradations level of Emulzin H, Ecocool and BC 25 achieved 80% in 10 days. It can be stated that these MWFs have potential to ultimate degradation, but the statement has to be confirmed by a biodegradability test with other parameters than COD, which exhibits some disadvantages in testing O/W emulsions.

The Study Into the Ceramic-to-Metal Soldered Joints Interface for Al2O3 and SiO2 Materials

The conditions of joining a ceramic-metal configuration by active metal soldering using tin-based (SnTi3) alloys are presented. Active metal (Ti) was alloyed in a low concentration of 3 weight percent. The joining process was carried out in a vacuum (10-2 Pa) at a peak temperature of 860 °C with a short holding period (t = 9 min). The ceramic-metal soldered interface was examined using optical microscopy, scanning and transmission electron microscopy (SEM, TEM). The natures of the interfacial reactions and the reaction products were identified using X-ray diffraction (XRD). The thickness of reaction layers and X-ray maps of the same region were measured.
La participation sociale des Canadiens : une analyse selon l'approche des parcours de vie
Authors: Gaudet Stéphanie
Published: March 2011

The level of participation of Canadians in civic and public life fell significantly between 1992 and 2005. A better understanding of this change in the life courses of Canadians could allow the development of policies that encourage the engagement of individuals within their communities. Until now, the development of such policies, and the longitudinal analyses done in Canada, have seldom incorporated the collective dimension of communities. In this article, we propose an indicator that makes it possible to include the interaction between individuals and their communities while maintaining an analysis centred on the individual and his or her life course. We propose to use the concept of social participation of an individual, defined as the gift of time to another individual or an organization, to capture formal (volunteering) and informal (mutual aid) contributions to the community. Data from the General Social Survey (GSS) on Time Use for the years 1992, 1998, and 2005 are used to understand changes in the practices of social participation in the lives of Canadians.

Object

Technical improvements in commercially available radiosurgery platforms have made it practical to treat a large number of intracranial targets. The goal of this study was to investigate whether the dose to normal brain when planning radiosurgery to multiple targets is apparatus dependent.

Methods

The authors selected a single case involving a patient with 12 metastatic lesions widely distributed throughout the brain as visualized on contrast-enhanced CT. Target volumes and critical normal structures were delineated with Leksell Gamma Knife Perfexion software. The imaging studies including the delineated contours were digitally exported into the CyberKnife and Novalis multileaf collimator–based planning systems for treatment planning using identical target dose goals and dose-volume constraints. Subsets of target combinations (3, 6, 9, or 12 targets) were planned separately to investigate the relationship of number of targets and radiosurgery platform to the dose to normal brain.

Results

Despite similar target dose coverage and dose to normal structures, the dose to normal brain was strongly apparatus dependent. A nonlinear increase in dose to normal brain volumes with increasing number of targets was also noted.

Conclusions

The dose delivered to normal brain is strongly dependent on the radiosurgery platform. How general this conclusion is and whether apparatus-dependent differences are related to differences in hardware design or differences in dose-planning algorithms deserve further investigation.

Authors: Quan Gerald M. , Vital Jean-Marc , Pointillart Vincent
Published: March 2011

Object

This prospective study was undertaken to assess the clinical outcome of 26 consecutive patients who underwent surgery for symptomatic metastases of the cervical or cervicothoracic spine.

Methods

All patients suffered axial or radicular pain, with or without neurological deficit, including radicular weakness (23%), quadriplegia or paraplegia (12%), and urinary sphincter dysfunction (8%). All patients underwent palliative decompression and stabilization surgery via an anterior (18 patients), posterior (7 patients) or combined approach (1 patient) depending on the topography of the metastases, and were prospectively followed up for 1 year. Thirteen patients received adjuvant chemotherapy and 7 patients received radiotherapy to the cervical lesion. Clinical data as well as data from the European Organization for Research and Treatment of Cancer QLQ-C30 questionnaire were obtained pre- and postoperatively and at regular follow-up intervals.

Results

Median survival was 6 months and 10 patients were known survivors at 12 months. Postoperatively, 1 patient developed neurological deterioration and died while an inpatient. There were no other early postoperative complications in any patients. From pre- to postoperatively there was an immediate and significant improvement in axial and radicular pain and overall quality of life. There was also overall improvement in cognitive, emotional, social, role, and physical functioning. The observed improvement in pain, functioning, and quality of life was maintained for the duration of the follow-up period. Furthermore, neurological function was improved or preserved until death in the majority of patients.

Conclusions

Together with adjuvant medical management, surgery for cervical metastases produces low morbidity and can achieve good symptomatic palliation in the majority of patients for their remaining lifetime.
Cell-Centric View of Apoptosis and Apoptotic Cell Death-Inducing Antitumoral Strategies
Authors: Apraiz Aintzane , Boyano Maria Dolores , Asumendi Aintzane
Published: March 2011

Programmed cell death and especially apoptotic cell death, occurs under physiological conditions and is also desirable under pathological circumstances. However, the more we learn about cellular signaling cascades, the less plausible it becomes to find restricted and well-limited signaling pathways. In this context, an extensive description of pathway-connections is necessary in order to point out the main regulatory molecules as well as to select the most appropriate therapeutic targets. On the other hand, irregularities in programmed cell death pathways often lead to tumor development and cancer-related mortality is projected to continue increasing despite the effort to develop more active and selective antitumoral compounds. In fact, tumor cell plasticity represents a major challenge in chemotherapy and improvement on anticancer therapies seems to rely on appropriate drug combinations. An overview of the current status regarding apoptotic pathways as well as available chemotherapeutic compounds provides a new perspective of possible future anticancer strategies.
Three Potential Sources of Microfungi in a Treated Municipal Water Supply System in Sub-Tropical Australia

Published: March 2011

Some microfungi are known to be opportunistic human pathogens, and there is a body of scientific opinion that one of their routes of infection may be water aerosols. Others have been implicated as causative agents of odours and off-tastes in drinking water. This study was undertaken to investigate three potential sources of microfungi in a treated, oligotrophic municipal water supply system in sub-tropical Australia. Formation of the microfungal component of developing biofilm on hard surfaces in water storage reservoirs was also assessed. Inside and outside air samples were collected from two reservoirs using two types of Burkard air samplers. Biofilm and soft sediment samples were collected from the inner surfaces of asbestos cement water pipes and from pipe dead ends respectively. These were analysed for microfungal growth and sporulation using Calcofluor White stain and epifluorescent microscopy. Artificial coupons of glass, PVC and concrete were immersed in two reservoirs to assess microfungal biofilm formation. This was analysed periodically using Calcofluor White stain and epifluorescent microscopy, cultures of coupon swabs and scanning electron microscopy. Fungal spores were recovered from all air samples. The number of colonies and the genera were similar for both inside and outside air. Microfungal filaments and sporulating structures were recovered from most of the pipe inner surface biofilm and dead end sediment samples, but were sparser in the biofilm than in the sediment samples. No recognisable, vegetative filamentous fungi were found in the slowly developing biofilm on coupons. This study indicates that airborne spores are an important potential source of microfungi found in water storage reservoirs. It has also demonstrated conclusively that filamentous microfungi grow and sporulate on water pipe inner surfaces and in soft sediments within the water distribution system.
The Composition and Organization of Cytoplasm in Prebiotic Cells
Authors: Trevors Jack T.
Published: March 2011

This article discusses the hypothesized composition and organization of cytoplasm in prebiotic cells from a theoretical perspective and also based upon what is currently known about bacterial cytoplasm. It is unknown if the first prebiotic, microscopic scale, cytoplasm was initially contained within a primitive, continuous, semipermeable membrane, or was an uncontained gel substance, that later became enclosed by a continuous membrane. Another possibility is that the first cytoplasm in prebiotic cells and a primitive membrane organized at the same time, permitting a rapid transition to the first cell(s) capable of growth and division, thus assisting with the emergence of life on Earth less than a billion years after the formation of the Earth. It is hypothesized that the organization and composition of cytoplasm progressed initially from an unstructured, microscopic hydrogel to a more complex cytoplasm, that may have been in the volume magnitude of about 0.1–0.2 µm3 (possibly less if a nanocell) prior to the first cell division.

Published: March 2011

Carotenoids are the most common pigments in nature and are synthesized by all photosynthetic organisms and fungi. Carotenoids are considered key molecules for life. Light capture, photosynthesis photoprotection, excess light dissipation and quenching of singlet oxygen are among key biological functions of carotenoids relevant for life on earth. Biological properties of carotenoids allow for a wide range of commercial applications. Indeed, recent interest in the carotenoids has been mainly for their nutraceutical properties. A large number of scientific studies have confirmed the benefits of carotenoids to health and their use for this purpose is growing rapidly. In addition, carotenoids have traditionally been used in food and animal feed for their color properties. Carotenoids are also known to improve consumer perception of quality; an example is the addition of carotenoids to fish feed to impart color to farmed salmon.
Volatile Organic Compound (VOC) Removal by Vapor Permeation at Low VOC Concentrations: Laboratory Scale Results and Modeling for Scale Up
Authors: Rebollar-Perez Georgette , Carretier Emilie , Lesage Nicolas , Moulin Philippe
Published: March 2011

Petroleum transformation industries have applied membrane processes for solvent and hydrocarbon recovery as an economic alternative to reduce their emissions and reuse evaporated components. Separation of the volatile organic compounds (VOCs) (toluene-propylene-butadiene) from air was performed using a poly dimethyl siloxane (PDMS)/α-alumina membrane. The experimental set-up followed the constant pressure/variable flow set-up and was operated at ~21 °C. The membrane is held in a stainless steel module and has a separation area of 55 × 10−4 m². Feed stream was set to atmospheric pressure and permeate side to vacuum between 3 and 5 mbar. To determine the performance of the module, the removed fraction of VOC was analyzed by Gas Chromatography/Flame Ionization Detector (GC/FID). The separation of the binary, ternary and quaternary hydrocarbon mixtures from air was performed at different flow rates and more especially at low concentrations. The permeate flux, permeance, enrichment factor, separation efficiency and the recovery extent of the membrane were determined as a function of these operating conditions. The permeability coefficients and the permeate flux through the composite PDMS-alumina membrane follow the order given by the Hildebrand parameter: toluene > 1,3-butadiene > propylene. The simulated data for the binary VOC/air mixtures showed fairly good agreement with the experimental results in the case of 1,3-butadiene and propylene. The discrepancies observed for toluene permeation could be minimized by taking into account the effects of the porous support and an influence of the concentration polarization. Finally, the installation of a 0.02 m2 membrane module would reduce 95% of the VOC content introduced at real concentration conditions used in the oil industry.
A Novel Multi-Aperture Based Sun Sensor Based on a Fast Multi-Point MEANSHIFT (FMMS) Algorithm
Authors: You Zheng , Sun Jian , Xing Fei , Zhang Gao-Fei
Published: March 2011

With the current increased widespread interest in the development and applications of micro/nanosatellites, it was found that we needed to design a small high accuracy satellite attitude determination system, because the star trackers widely used in large satellites are large and heavy, and therefore not suitable for installation on micro/nanosatellites. A Sun sensor + magnetometer is proven to be a better alternative, but the conventional sun sensor has low accuracy, and cannot meet the requirements of the attitude determination systems of micro/nanosatellites, so the development of a small high accuracy sun sensor with high reliability is very significant. This paper presents a multi-aperture based sun sensor, which is composed of a micro-electro-mechanical system (MEMS) mask with 36 apertures and an active pixels sensor (APS) CMOS placed below the mask at a certain distance. A novel fast multi-point MEANSHIFT (FMMS) algorithm is proposed to improve the accuracy and reliability, the two key performance features, of an APS sun sensor. When the sunlight illuminates the sensor, a sun spot array image is formed on the APS detector. Then the sun angles can be derived by analyzing the aperture image location on the detector via the FMMS algorithm. With this system, the centroid accuracy of the sun image can reach 0.01 pixels, without increasing the weight and power consumption, even when some missing apertures and bad pixels appear on the detector due to aging of the devices and operation in a harsh space environment, while the pointing accuracy of the single-aperture sun sensor using the conventional correlation algorithm is only 0.05 pixels.

We review existing query answering systems for sensor data. We then propose an extended query answering approach termed smart query, specifically for marine sensor data. The smart query answering system integrates pattern queries and continuous queries. The proposed smart query system considers both streaming data and historical data from marine sensor networks. The smart query also uses query relaxation technique and semantics from domain knowledge as a recommender system. The proposed smart query benefits in building data and information systems for marine sensor networks.

Résumé Dans son travail de pensée, l’analyste utilise la métapsychologie qu’il a élaborée au fil de son expérience théorico-clinique. De multiples éléments entrent dans la composition de cette métapsychologie, dont des modèles théoriques, des concepts, mais aussi des éléments littéraires. Ainsi l’analyste peut-il être amené à penser la clinique qu’il a à connaître au moyen de l’œuvre littéraire : l’analyste entretient avec « son » écrivain une relation de pensée, de développement d’une élaboration, de telle sorte que l’objet littéraire devient un objet psychanalytique. Raymond Queneau et son œuvre en constituent ici un exemple éprouvé.
En chemin avec André Du Bouchet

Published: March 2011

Résumé À partir du thème proposé (« le psychanalyste et son écrivain »), l’auteur témoigne de sa rencontre avec le poète André Du Bouchet. Poursuivant un dialogue entamé de longue date avec le poète, l’auteur met d’entrée en question l’idée d’une lecture psychanalytique du texte littéraire : lecture qui traiterait exclusivement le texte à la manière d’un symptôme, en proposant des interprétations « sur » le texte. Le présent article tente de faire éprouver, dans la rencontre du texte poétique, les limites d’une telle méthode, de faire saillir les points de basculement où l’analyste, destitué de sa place d’interprète, se fait soudain interpréter, jouer, bousculer par une langue qui semble échapper à sa symptomatologie, trouve des « solutions de langue » inédites. L’analyste lecteur sera particulièrement sensible à une poésie qui se propose de « transmutter le terrible et l’intolérable en fraîcheur ».
Les cris vains du psychanalyste ou le livre encrypté
Authors: Lévy Ghyslain
Published: March 2011

Résumé L’intitulé paradoxal « Le psychanalyste et son écrivain » pose plus globalement la question de ce qu’on pourrait appeler le sujet écrit. Qu’en serait-il d’un processus analytique de construction subjective analogiquement pensé comme un processus de lecture, plus précisément d’autolecture, de lecture d’un soi qui se déchiffrerait à partir d’un texte palimpseste, livre secret, encrypté, à partir duquel le sujet « aurait été écrit » ? Le lecteur serait un sujet en devenir qui, comme l’analysant en séance, ferait de la parole à l’œuvre, ou de l’écriture devenue acte de parole, l’opérateur d’une transformation intérieure fondamentale. Retrouvant la fonction déliante de la parole au vif de l’analyse, dé-lire le texte écrit renvoie à la violence dévoilante de la littérature, et vient éclairer autrement les relations complexes que celle-ci entretient avec la psychanalyse, en particulier la poétique littéraire de la langue analytique. Philippines , le dernier livre de Hélène Cixous, fonctionne ici comme ce texte encrypté qui fait soudain retour dans la séance d’analyse en prenant simultanément possession de l’écoute de l’analyste et de la parole analysante, par un effet de transfert immédiat. Le livre serait l’enveloppe d’une promesse d’amour avec son lecteur, comme la situation analytique est l’enveloppe d’une promesse de transfert entre l’analysant et l’analyste, l’enveloppe des deux amandes jumelles qui « font philippines » … Le livre comme la séance analytique remontent, chacun à sa façon, le chemin qui va du trop singulier au commun. Ils rebroussent vers les enfances, les fantômes, les anciens, les ruines.
Entre les œuvres vives et les œuvres mortes …, une ligne d'ombre
Authors: Guillaumin Jean-Baptiste
Published: March 2011

Résumé La psychanalyse serait-elle une « poésie scientifique et une science poétique » ? L’émergence de la poésie en séance ne serait-elle pas une tentative de créer une expérience limite, aux limites du savoir, pour suturer les inscriptions représentatives manquantes de l’irreprésentable des origines ? La poésie, pour l’analysant « géologie du langage », l’écriture « ligne d’ombre sur papier blanc » pour l’analyste, rendraient compte d’une tentative de figuration de l’impensable primitivité de l’être qui opérerait sous la forme d’une « négativité ouverte », fruit des imprésivibles faillites du savoir sur soi.
Freud et Grimm : l'influence d'une lecture d'enfance

Résumé À travers un conte de Grimm, l’auteur trace l’influence et l’impact d’une lecture d’enfance pour Freud. Cette lecture d’enfance constitue un aspect de l’élaboration théorique du transfert et du contre-transfert dans les écrits et la pensée de Freud. La relation analytique est éclairée par cette notion d’échange et de troc. Le périple de Hans, le personnage du conte, y apparaît à l’image d’un retour aux origines, au sein maternel, et aussi un voyage vers la mort.
En parlant, en écrivant … traiter le réel : une métamorphose ?

Résumé Partir des textes romanesques de Philippe Forest, en particulier L’enfant éternel pour lequel il devait se voir décerner le prix Fémina du premier roman, en 1997, en passant par ses essais critiques réunis dans le recueil Le roman, le réel paru dix ans plus tard. C’est le temps qu’il lui aura fallu pour dire l’intolérable douleur de la perte d’un enfant, et quatre livres pour venir à bout (?) de l’expérience traumatique, quatre livres endeuillés qui font de l’événement et de sa répétition voire de son ressassement, porté par une écriture d’une grande exigence, le récit de la vie et de la mort-enfant, et la matière même d’une théorie de l’œuvre romanesque dans sa forme autofictionnelle. Si la démarche de Forest intéresse particulièrement le lecteur psychanalyste, c’est en ce qu’elle met en perspective la nécessité d’une parole, d’une écriture au plus près de la chose vécue en prenant le risque de la fiction, c’est-à-dire de son écart, de son indépendance souveraine. En est-il de même pour la parole en séance ? Ne sommes-nous pas attentifs, en effet, aux opérations de transformation plus ou moins consenties qui vont de l’expression d’une souffrance à l’émergence d’un discours ; c’est le pari de l’association dite « libre » qui, faisant de cette souffrance ou de cette plainte son objet, n’en construit pas moins une réalité autre, un espace de fiction. Une fiction repérable en premier lieu dans les jeux et enjeux transférentiels.

Résumé « À la recherche désespérée des mots » aurait pu être le titre de ce travail, puisque c’est l’absence de ces mots dont il s’agit et qui signe impitoyablement des destinées comme celle d’Artaud. La place que cette absence occupe dans la rencontre psychanalytique est très significative, non pas à cause des mots non dits, puisque hélas, ils n’ont jamais existé, mais à cause de tous les autres langages qui font leur rentrée dans la scène psychanalytique par le biais des Signes. Des Signes qui, si on veut bien les accueillir autrement que comme des objets « psychotiques », permettront de découvrir, dans la Forme qu’ils prennent, que l’inscription d’anciens scénarios « muets » fait partie d’une mémoire physiologique capable de restituer au « corps-déchet-déçu » son statut de sujet « des langages ».
Les identifications d'Arthur Rimbaud
Authors: Clavier Bruno
Published: March 2011

Résumé Dans ses premières définitions de l’Œdipe, Freud associait au mythe grec la tragédie de Hamlet dans laquelle il n’est pas question de rivalité avec le père mais avec l’oncle paternel. Des histoires familiales montrent fréquemment comment un oncle, cette fois-ci maternel, peut représenter un modèle d’identification inconsciente en lieu et place d’un père défaillant. Après une fulgurante œuvre poétique, Arthur Rimbaud aurait poursuivi sa vie en Afrique sur les traces de son père, ancien militaire sur ce continent. Cependant, il semble que le poète ait été bien plus fortement hanté par son oncle maternel dont il eut pratiquement le même destin, oncle révolté et fugueur qui s’engagea à 17 ans dans la légion d’Afrique après une « méchante affaire », au désespoir des siens. Le jeune Arthur se serait alors identifié au frère de sa mère, décédé quand il avait 1 an : la construction œdipienne se révèle donc, dans ce cas, plus complexe qu’une triangulation classique de type « enfant-père-mère ».
Le poème est le patient privilégié. Conséquences pour la construction du cas en psychanalyse
Authors: Landa Fabio
Published: March 2011

Résumé À partir d’une remarque de Nicolas Abraham, « le poème est le patient privilegié de la psychanalyse », l’auteur essaie dans cet article de mettre en valeur la dimension poétique de la communication psychanalytique et de s’approcher de l’instant où la construction en analyse (Freud) peut avoir lieu.
De la Chose, fondement paradoxal de l'Être
Authors: Réfabert Philippe
Published: March 2011

Résumé De la séduction vue comme un obstacle mis par la mère à la constitution de la Chose. La Chose, considérée ici comme la part non semblable qui résulte d’une scission de l’Objet. La « mère suffisamment bonne » serait celle qui laisserait scinder la représentation d’elle-même en une part semblable, affectable, et une part non semblable mais constante. Une mère excitante, activement ou passivement, serait celle qui empêcherait une telle scission. Faute de pouvoir scinder la représentation de l’objet en une part mobile et une part fixe, l’infans , parfois, se scinde lui-même.
La psychanalyse à la conquête de l'Ouest : un fléau ?
Authors: de Spengler Nina

Résumé L’auteur cherche à retrouver l’histoire d’une phrase régulièrement citée et attribuée à Freud par des psychanalystes, dans un mouvement identitaire : « Ils ne savent pas que nous leur apportons la peste. »
Freud avec Halbwachs : les conditions d'une inscription symbolique
Authors: Topalov Annie
Published: March 2011

Résumé La réédition critique de La topographie légendaire des évangiles en Terre sainte de Maurice Halbwachs offre une occasion de s’interroger sur les rapports entre la mémoire collective chez ce sociologue, disciple de Durkheim, et le refoulement chez Freud. Halbwachs ne s’intéresse pas à la véracité historique des récits des évangiles, mais à la formation d’une mémoire collective comme une somme d’histoires perdues attachées à des lieux et soutenues par des groupes. Penser l’origine, chez Freud, est indissociable de l’analyse du processus de refoulement primaire qui conditionne l’inscription du sujet dans son histoire. C’est en cela que l’origine n’advient que sous la forme d’un mythe, d’une narration légendaire ou d’une métapsychologie. L’article observe, à partir des Fables de la mémoire de Lucette Valensi, comment les historiens d’aujourd’hui ont pris pour objet les façons changeantes dont ont été construits et mobilisés les récits du passé. De façon analogue, le retour du refoulé n’est pas le mirage d’une origine enfin dévoilée, comme dans Citizen Kane , mais la modification d’un point de vue sur le monde et la création de nouveaux espaces de pensée.
Topological Free Entropy Dimensions in Nuclear C*-algebras and in Full Free Products of Unital C*-algebras
Authors: Hadwin Don , Li Qihui , Shen Junhao
Published: March 2011

In the paper, we introduce a new concept, topological orbit dimension of an n-tuple of elements in a unital C*-algebra. Using this concept, we conclude that Voiculescu's topological free entropy dimension of every finite family of self-adjoint generators of a nuclear C*-algebra is less than or equal to 1. We also show that the Voiculescu's topological free entropy dimension is additive in the full free product of some unital C*-algebras. We show that the unital full free product of Blackadar and Kirchberg's unital MF algebras is also an MF algebra. As an application, we obtain that Ext(C*r (F2) *C C* r (F2)) is not a group.
Quasi-isometry and Plaque Expansiveness
Authors: Hammerlindl Andy
Published: March 2011

We show that a partially hyperbolic diffeomorphism is plaque expansive (a form of structural stability for its center foliation) if the strong stable and unstable foliations are quasi-isometric in the universal cover. In particular, all partially hyperbolic diffeomorphisms on the 3-torus are plaque expansive.
Implantation Failure, Etiology, Diagnosis and Treatment
Authors: Shufaro Yoel , Schenker Joseph G
Published: March 2011

Embryonic implantation is a complex interaction between the embryo and the endometrium. Despite great investigative effort this process is still obscure. Contrary to the great advancement in patient care, follicular recruitment, oocyte quality and aspiration, embryo quality, culture and cryopreservation, our understanding of the implantation process did not enhance as much, and the tools to intervene within this process are limited. The implantation of the transferred embryos still remains the major limiting factor in IVF. Here we will review the current literature on the maternal (uterine, hematologic, immunologic and others) and embryonic factors that are associated with repeated implantation failure (RIF) and describe the various therapeutic approaches to cope with them. In addition, we will present our conclusive recommendations on how to investigate and manage RIF based on the literature and our own experience.
Endometrioma and ART: Does the Needle Work?
Authors: Patil Madhuri , Hagargi Rashmi P
Published: March 2011

Aim and Objectives

The aim of this study was to see if the fertility outcome improved when IVF/ICSI was done after administration of GnRH analogs and cyst aspiration in comparison with patients in whom either only cyst aspiration or only GnRh analogs were administered.

Materials and methods

This was a prospective study done in a tertiary level ART center which included 30 patients over a span of 5 years from 2004 to 2009. All of them had endometriomas and underwent assisted reproductive techniques (ART) either after cyst aspiration with or without GnRH analog pretreatment or only GnRH analog pretreatment.

Depending on the pretreatment received, they were classified into three groups:

• Group B: Both GnRH analog and cyst aspiration

• Group C: Only cyst aspiration

• Group G: Only GnRH analog.

The patients were not randomized.

The number of days required for stimulation, total dose of stimulation required, number of oocytes obtained, quality of embryos, and the pregnancy rates for each group were tabulated for comparison.

Statistical analysis

The significance of the difference in ART outcome after the different modalities of pretreatment, which was estimated in terms of pregnancy rates was evaluated by calculating the p-value.

Observations and results

Significant difference was observed between the pregnancy rates in the three groups, with the maximum pregnancy rate in group B, followed by the group G and then the group C. The p-value showed a trend, though not statistically significant, indicating the need for larger prospective studies with greater number of subjects.

Conclusion

Pretreating endometriomas by aspirating the cysts and administering three doses of GnRH analog depot preparation prior to IVF/ICSI seems to be better than administering GnRH analog depot preparation alone or aspirating the cysts alone in terms of the number of days required for stimulation, the number of oocytes obtained, and the clinical pregnancy rates.
Heritage, Neighborhoods and Cosmopolitan Sensibilities: Poly-Communal Archaeology in Deerfield, Massachusetts
Authors: Hart Siobhan
Published: March 2011

Cosmopolitan sensibilities acknowledging mutual obligations and human interconnectedness can orient people navigating the complexities of neighborhood and other forms of community-based archaeology. I suggest that practice aimed at engaging in ethical heritage work in neighborhoods can benefit from fostering cosmopolitan values among participants and stakeholders. I outline a model for “poly-communal archaeology,” an approach that takes a cosmopolitan stance and engages multiple stakeholders in neighborhood archaeology and heritage work. I then reflect on a case study of heritage work that employs such an approach in the neighborhood of “Old Deerfield” in western Massachusetts, U.S.A. In this case, a cosmopolitan sensibility is deployed to restructure the social relations that underpin heritage work.
Searching for the Real Florida in the Land of Make Believe: Historical Archaeology as Public Archaeology, Orange County, Florida
Authors: Wenzel Jason , George Tiffany
Published: March 2011

Orange County encompasses the city of Orlando and is home to over one million residents and attracts millions of tourists annually. Starting in the twentieth century, areas in the county sustained intensive agricultural use and later massive residential and commercial development. As a result of these activities, natural and historic areas were spoiled while others vanished completely. Prior to the 1970s and the establishment of Walt Disney World, the area’s tourism industry revolved primarily around its natural amenities, only to be supplanted by a form that was thematic and “make believe”. In 2006, an archaeology program was initiated to unearth the county’s early history as a way of searching for the “real Florida.” This paper will discuss how public archaeology has the potential for addressing problems that affect cultural and natural resources as history is unearthed at the neighborhood level.
Longitudinal consequences of adolescent bullying perpetration and victimisation: A study of students in Victoria, Australia
Authors: Hemphill Sheryl A. , Kotevski Aneta , Herrenkohl Todd I. , Bond Lyndal , Kim Min Jung , Toumbourou John W. , Catalano Richard F.
Published: March 2011

Aims To examine the associations between self‐reported bullying perpetration and victimisation in Years 7 and 10 and a range of psychosocial outcomes in Year 11.

Method This analysis draws on data from the International Youth Development Study, a longitudinal study of 5769 students from Victoria, Australia and Washington State, United States who were recruited through schools in Years 5, 7 and 9 in 2002. Data for the current results are taken from participants in the youngest (Year 5) Victorian cohort of the study.

Results Rates of bullying victimisation exceeded 30% and up to one in five students had engaged in bullying. Adjusted logistic regression analyses revealed that bullying perpetration, and bullying victimisation in Year 7 did not significantly predict psychosocial outcomes in Year 11. Bullying perpetration in Year 10 was associated with an increased likelihood of theft, violent behaviour and binge drinking. Year 10 bullying victimisation was associated with an increased likelihood of Year 11 depressive symptoms.

Conclusions Prevention approaches that target bullying perpetration and victimisation are necessary. Programmes that lessen bullying may also have an impact on other proximally related behaviours, including binge drinking and depression. Copyright © 2011 John Wiley & Sons, Ltd.
