Estimation de la biomasse en culture dans l'étang de Thau (été 1980)

Le laboratoire de Biologie conchylicole de l'I.S. T.P.M. de Sete suit depuis de nombreuses annees l'evolution des cultures dans l'etang de Thau. Ses travaux ont deja conduit a la mise en oeuvre du reamenagement des zones conchylicoles qui, depuis 1970, substitue progressivement a une disposition anarchique et trop dense des parcs une implantation rationnelle et un large espacement afin d'accroitre la production et d'ameliorer la qualite. Par ailleurs, le but poursuivi etant d'apporter aux professionnels ses conseils scientifiques et techniques, le laboratoire est amene a rechercher en permanence de meilleures conditions de culture par : le suivi des conditions du milieu et de la croissance ; l'examen du plancton et de la valeur alimentaire des eaux ; la recherche de moyens de lutte contre les accidents episodiques (predation par les daurades, mortalites a l'occasion de malaigue , pollutions, etc . ) ; l'essai de determination des charges optimales des parcs en moules ou en huitres selon les differents types de culture utilises. C'est en 1979 que ce dernier probleme a ete aborde. Les premieres observations ont permis de mettre au point une methode d'echantillonnage et de traitement. Les donnees recueillies en 1980, beaucoup plus completes que celles de l'annee precedente, permettent d'etudier la gestion du plan d'eau et d'aborder le probleme de la biomasse des mollusques en elevage en suspension. Cette publication fait le point des deux annees d'etude.
The Sm‐like protein Hfq regulates polyadenylation dependent mRNA decay in Escherichia coli

In Escherichia coli, the post‐transcriptional addition of poly(A) tails by poly(A) polymerase I (PAP I, pcnB) plays a significant role in cellular RNA metabolism. However, many important features of this system, including its regulation and the selection of polyadenylation sites, are still poorly understood. Here we show that the inactivation of Hfq (hfq), an abundant RNA‐binding protein, leads to the reduction in the ability of PAP I to add poly(A) tails at the 3′ termini of mRNAs containing Rho‐independent transcription terminators even though PAP I protein levels remain unchanged. Those poly(A) tails that are synthesized in the absence of Hfq are shorter in length, even in the absence of polynucleotide phosphorylase (PNPase), RNase II and RNase E. In fact, the biosynthetic activity of PNPase in the hfq single mutant is enhanced and it becomes the primary polynucleotide polymerase, adding heteropolymeric tails almost exclusively to 3′ truncated mRNAs. Surprisingly, both PNPase and Hfq co‐purified with His‐tagged PAP I under native conditions indicating a potential complex among these proteins. Immunoprecipitation experiments using PNPase‐ and Hfq‐specific antibodies confirmed the protein–protein interactions among PAP I, PNPase and Hfq. Analysis of mRNA half‐lives in hfq, ΔpcnB and hfq ΔpcnB mutants suggests that Hfq and PAP I function in the same mRNA decay pathway.
Model for auditory localization.

A mathematical model based on statistical decision theory has been devised to represent the human auditory localization task. The known localization cues have been represented as Gaussian random variables, so that their interaction in a given experiment can be analyzed (and predicted) along the lines of classical detection/estimation theory. We have applied this technique to most of the horizontal and vertical localization experiments reported in the literature during the past ten years, encompassing over 200 subjects and 20 000 trials. Using a nonlinear regression program we have been able to estimate the standard deviations of four of the auditory localization cues, allowing objective comparison of their relative accuracy. The resulting model provides a relatively good fit to the published results on 40 localization experiments.Subject Classification: [43]65.62, [43]65.58, [43]65.35.

Performance Analysis of Turbo Codes over Nakagami-m Fading Channels with Impulsive Noise

The statistical characteristics of impulsive noise differ greatly from those of Gaussian noise. Hence, the performance of conventional decoders, optimized for AWGN channels is not promising in non-Gaussian environments. In order to achieve improved performance in impulsive environments the decoder structure needs to be adapted in accordance with the impulsive noise model. This paper provides performance analysis of turbo codes over fully interleaved Nakagami-m fading channels with Mid- dleton's additive white Class-A impulsive noise (MAWCAIN). Simulation results for memoryless Nakagami-m fading channels under coherent BPSK signaling are provided for the cases of ideal channel state information (ICSI) and no channel state information (NCSI) at the decoder. As in the 3GPP UMTS forward link an eight state turbo encoder having (1, 13/15,13/15) generator polynomial is used throughout the analysis. The novelty of this work lies in the fact that this is an initial attempt to provide a detailed analysis of turbo codes over Nakagami-m fading channels with impulsive noise rather than fading channels with AWGN.
[Cardiovascular risks during isokinetic tests for peripheral functional studies].

OBJECTIVES Isokinetic tests used to assess both muscle function and joint disorders stimulate the entire organism and in particular the cardiovascular system. We evaluated the risk of cardiovascular or vascular impairment during isokinetic knee extension and flexion tests. METHODS Cardiac electrical activity, heart rate and systolic and diastolic blood pressures were measured in 251 patients during 50-sec isokinetic tests. RESULTS Abnormal findings were recorded in 15 patients (5.9%) including 6 with altered blood pressure, 4 with altered cardiac electrical activity and 5 with heart rate abnormalities. Maximal heart rate for a given subject recorded during the isokinetic test was 199 beats per minute and heart rate exceeded 190 bpm in 92 subjects (36.6%). Maximal efforts with cardiac barometric charge produced dramatic, occasionally pathological, changes in heart rate or blood pressure. CONCLUSION These findings emphasize the need to carefully assess patients before isokinetic tests and carefully monitor cardiovascular parameters. A preliminary physical examination and medical surveillance during testing are required.
Non servono "moniti" se manca una bussola

Poco piu di un anno fa un folto gruppo di economisti di diversi paesi ha lanciato un monito, pubblicato sul Financial Times del 23/9/2013. Il succo dell’appello era ben riassunto dalle conclusioni: “Occorre essere consapevoli che proseguendo con le politiche di ‘austerita’ e affidando il riequilibrio alle cosiddette ‘riforme strutturali’ il destino dell’euro sara segnato: l’esperienza della moneta unica si esaurira, con ripercussioni sulla tenuta del mercato unico europeo. In assenza di condizioni per una riforma del sistema finanziario e della politica monetaria e fiscale che dia vita a un piano di rilancio degli investimenti pubblici e privati, contrasti le sperequazioni tra i redditi e tra i territori e risollevi l’occupazione nelle periferie dell’Unione, ai decisori politici non restera altro che una scelta cruciale tra modalita alternative di uscita dall’euro”. Ma che cosa succede se la caduta degli investimenti pubblici e privati, l’accentuato squilibrio tra i redditi, l’esplodere della disoccupazione di massa e perfino l’eventuale futura fuga dell’euro, sono sintomi della crisi, non le sue cause? Succede com’e successo – che il monito lascia il tempo che trova, e cioe non sortisce gli effetti sperati. Ne basta insistere sulla sua attualita, come hanno fatto Brancaccio e Zezza sull’ultimo numero di Critica Marxista, per ottenere qualcosa di diverso.
A delay-based constrained beamformer for blind speech enhancement and dereverberation

This paper presents a new microphone array method to enhance speech signals in a noisy reverberant environment. A time-delay estimation method is used for the speech source localization. The robustness of the localization method in high noise levels is provided by a subband Kurtosis-weighted structure. The estimated inter-sensor time-delays are directly used in an adaptive soft-constrained subband beamformer. Evaluation in a simulated environment with real speech sequences shows promising results.
PROPOSAL FOR A CANDIDATE GSSP FOR THE BASE OF THE RHAETIAN STAGE

The Steinbergkogel section near Hallstatt, Salzkammergut, Austria is proposed as candidadate GSSP for the Norian-Rhaetian boundary (NRB). Following a recommendation of the Subcommission on Triassic Stratigraphy the boundary is defined by conodonts, with two alternative positions located closely upon each other. The lower event (option 1) corresponds to the FA of Misikella hernsteini 1.80 m above section base, it is followed by the FAD of Misikella posthernsteini 40 cm higher up (option 2). Accompanying biostratigraphic boundary markers for option 1 are the FA of the ammonoids Paracochloceras suessi coeval to the FAD of M. posthernsteini and of Sagenites s.str. at about the same level. Option 1 is marked by the LA of Metasibirites, a widespread late Norian ammonoid genus, just below the FA of M. hernsteini. Another proxy for option 1 is the worldwide disappearance of Monotis (M. salinaria/subcircularis in low palaelatitudes and M. ochotica group in the Boreal) closely below the FA of M. hernsteini. Half way above the 40 cm thick boundary interval lies a prominent magnetic polarity change from a long Normal to a distinct Reversal which can be recognized in other Tethyan magnetostratigraphies and, by a comparable polarity signature is identified in the lacustrine Newark magnetochronology too. The Ccarb record is well preserved but unfortunately no significant variations occur around the two boundary options. The Steinbergkogel exposes a pelagic basin facies of red and gray Middle Norian to Lower Rhaetian Hallstatt Limestone with a rich ammonoid and conodont fauna that allows a cross-correlation of the respective zonal schemes around the NRB. A lithologically uniform boundary interval, good exposure conditions in an old abondoned quarry and location on public land in a mountainous forested area assure long-time preservation and accessibility.
Poststroke seizures.

Stroke is the most common cause of seizures in the elderly, and seizures are among the most common neurologic sequelae of stroke. About 10% of all stroke patients experience seizures, from stroke onset until several years later. This review discusses current understanding of the epidemiology, pathogenesis, classification, clinical manifestations, diagnostic studies, differential diagnosis, and management issues of seizures associated with various cerebrovascular lesions, with a focus on anticonvulsant use in the elderly.
Escherichia coli DNA Polymerase V Subunit Exchange

DNA polymerase V consisting of a heterotrimer composed of one molecule of UmuC and two molecules of UmuD′ (UmuD′2C) is responsible for SOS damage-induced mutagenesis in Escherichia coli. Here we show that although the UmuD′2C complex remains intact through multiple chromatographic steps, excess UmuD, the precursor to UmuD′, displaces UmuD′ from UmuD′2C by forming a UmuDD′ heterodimer, while UmuC concomitantly aggregates as an insoluble precipitate. Although soluble UmuD′2C is readily detected when the two genes are co-transcribed and translated in vitro, soluble UmuD2C or UmuDD′C are not detected. The subunit exchange between UmuD′2C and UmuD offers a biological means to inactivate error-prone polymerase V following translesion synthesis, thus preventing mutations from occurring on undamaged DNA.
Therapeutic strategies and nano-drug delivery applications in management of ageing Alzheimer’s disease

Abstract In recent years, the incidental rate of neurodegenerative disorders has increased proportionately with the aging population. Alzheimer’s disease (AD) is one of the most commonly reported neurodegenerative disorders, and it is estimated to increase by roughly 30% among the aged population. In spite of screening numerous drug candidates against various molecular targets of AD, only a few candidates – such as acetylcholinesterase inhibitors are currently utilized as an effective clinical therapy. However, targeted drug delivery of these drugs to the central nervous system (CNS) exhibits several limitations including meager solubility, low bioavailability, and reduced efficiency due to the impediments of the blood-brain barrier (BBB). Current advances in nanotechnology present opportunities to overcome such limitations in delivering active drug candidates. Nanodrug delivery systems are promising in targeting several therapeutic moieties by easing the penetration of drug molecules across the CNS and improving their bioavailability. Recently, a wide range of nano-carriers, such as polymers, emulsions, lipo-carriers, solid lipid carriers, carbon nanotubes, metal based carriers etc., have been adapted to develop successful therapeutics with sustained release and improved efficacy. Here, we discuss few recently updated nano-drug delivery applications that have been adapted in the field of AD therapeutics, and future prospects on potential molecular targets for nano-drug delivery systems.
Plasma androgens in male schizophrenics.

Peripheral plasma androgen levels have been studied in control subjects, acute, chronic institutionalized, and chronic noninstitutionalized schizophrenic patients. The androgens determined included testosterone, dehydroandrosterone, and androstenedione. The schizophrenic groups did not show any significant difference from controls for plasma levels of testosterone and androstenedione. Both chronic schizophrenic groups have a significantly lower level of dehydroandrosterone. This change appears to be independent of age and institutionalization variables. Dehydroandrosterone is derived principally from the adrenal cortex and this suggests the possibility of reduced adrenal cortical functioning in chronic schizophrenia.
Applying Information Retrieval for Market Basket Recommender Systems

Coded data sets form the basis for many well known applications from healthcare prospective payment system to recommender systems in online shopping. Previous studies on coded data sets have introduced methods for the analysis of rather small data sets. This study proposes applying information retrieval methods for enabling high performance analysis of data masses that scale beyond traditional approaches. An essential component in today’s data warehouses to which coded data sets are collected is a database management system (DBMS). This study presents experimental results how information retrieval indexes scale and outperform common database schemas with a leading commercial DBMS engine in analysis of coded data sets. The results show that flexible analysis of hundreds of millions of coded data sets is possible with a regular desktop hardware.
International Conference on Emerging Ubiquitous Systems and Pervasive Networks ( EUSPN 2017 ) Fast Cloud-RSA Scheme for Promoting Data Confidentiality in the Cloud Computing

Confidentiality is among the most important obstacles for widespread adoption of cloud services. In fact, researchers have invented a new promising form of encryption, homomorphic encryption, that can be considered as an effective way to overcome these obstacles. Since cloud computing environment is more threatened by attacks and since cloud consumers often use resourceconstrained devices to access to cloud computing services, the homomorphic encryption schemes must be promoted, in terms of security level and running time, to work efficiently. At EMENA-TSSL’16, we boosted the standard RSA encryption scheme at security level, Cloud-RSA. In this paper, we propose a new fast variant of the Cloud-RSA scheme to speed up its algorithms. The proposed variant uses a modulus of the form N = prqs for r, s ≥ 2 and employs Hensel lifting and Chinese remaindering to decrypt. Simulation results show that the proposed variant gives a large speed up over the Cloud-RSA scheme while preserving a prescribed security level. c ⃝ 2017 he uthors.

Adductor Canal Block for Post-Operative Pain Relief in Knee Surgeries: A Review Article

The adductor canal block (ACB) is newer compartment block of the saphenous nerve, which is a branch of femoral nerve, performed at the level of lower third of the thigh so that much of the motor innervation of the quadriceps group is spared, thus preserving much of the quadriceps strength making early ambulation and rehabilitation safer. The most significant advantage of the ACB over femoral nerve block and other techniques is that it is predominantly a sensory block and reduces the incidence of fall after knee surgeries.
Perilous journey: Canadian nursing research in 2009.

column was: “From a leader’s perspective, what will change in nursing research over the next five years? ” The question carries with it a number of assumptions – that I in some way fulfill the requirement for leadership, that I know with some precision where nursing research is in 2003 and that I can foretell the (albeit short-term) future. Feeling on shaky ground on at least two of these assumptions, I turned to others – in and outside the nursing profession, well known and not – for direction. My colleagues foretold glory days, gnashed teeth, told me what should be, wrung hands and presaged a barren, post-apocalyptic landscape. A few ignored me. With little recourse, I resolved to create a new question, one I could answer. My complaints about the original question were numerous: it was the wrong question; it was not nearly a long enough period of time in which to see observable change; it wasn’t an important enough question; and why wasn’t I given the better question: What should change in five years? I did not arrive at a newer and better question, and so found myself alone again . the cursor blinking unremittingly. Sometime during the last procrastinating trip out to prune the roses, I decided there was nothing to do but answer the question based on my travels, recently attended research events, the spate of reports written lately on nurses and conversations with countless nurses in the past 25 years. I do not know with objective precision the state of nursing research in Canada today, nor can I predict the future, even in the short term. But here are my best efforts as a successful career scientist in this country, working in a field that 10 years ago was proclaimed by some as nonviable. I will make my predictions after a quick glance at four recent events. Perilous Journey: Canadian Nursing Research in 2009
Data glove with a force sensor

This paper presents a data glove equipped with a force sensor. The circuits and the construction are also described. The glove is selected to be a rubber coated cotton glove. The sensors are firmly attached to the rubber coated glove using cyanoacrylic glue. The force sensor is made of a steel plate substrate were the commercial strain gauges are attached. The plate is attached on the thumb. The strain gauges bridge is powered by a digital current source. A digital sine is produced by a microcontroller and a DAC with current output. At the peak the microcontroller produces a digital output signal. It is used by the data acquisition system. The force sensor presents a linear response and a resolution of 0.38 N and a sensitivity of 0.05 V/N. The combination can be used in robotics, telecheric applications, biomechanics and virtual reality applications.
Comparison of Two Commercially Available Gamma Interferon Blood Tests for Immunodiagnosis of Tuberculosis

ABSTRACT We evaluated the T-SPOT.TB and Quantiferon-TB Gold In tube (QFN-G-IT) tests for diagnosing Mycobacterium tuberculosis infection. T-SPOT.TB was more sensitive than QFN-G-IT in diagnosing both active and latent infection. Both gamma interferon tests were unaffected by prior Mycobacterium bovis BCG vaccination. Among children who were not BCG vaccinated but had a positive tuberculin skin test, QFN-G-IT was negative in 53.3% of cases, and T-SPOT.TB was negative in 50% of cases.
The Geography of Economic Freedom

The idea that economic institutions are determinants of long-run economic performance is largely associated with the work of Douglass North and several other economists in the post-War period. Although the importance of institutions has been recognized by many authors since at least Adam Smith (1776), much of post-War economics research ignored the importance of institutions for economic growth and development. The seminal textbook of the post-war period, Samuelson’s Economics: An Introductory Analysis (1946), does not even include the word “institutions” in its index. Much of economics in the postWar decades was following Samuelson’s path and thus also ignored institutions. North’s less mainstream research over several decades provides the primary arguments for why institutions matter. “The evolution of institutions that create an hospitable environment for cooperative solutions to complex exchange provides for economic growth” (North 1990, vii). According to North, institutions are the “rules of the game” in an economy or “the humanly devised constraints that shape human interaction” (North 1990, 3). The broad, yet vague, nature of this definition simultaneously reveals the importance of institutions and the difficulty of integrating them into mainstream economics research. The lack of concrete empirical approaches to the topic of institutions helped ensure that they were absent from most of the economics literature of the twentieth century. Several important events helped institutions gain a more prominent role in the economics literature in recent years: 1) the collapse of the Soviet Union and its intellectual foundations (economic theorists were ‘mugged by reality’), 2) North’s
