Published: April 2012

Résumé L'accent mis sur les énergies renouvelables et les inquiétudes environnementales ont conduit, dans le monde entier, à un développement considérable des techniques éoliennes. Ces énergies, toutefois, ne sont pas sans poser des défis importants, liés au caractère intermittent et instable du vent. Les prévisions à court terme dans ce domaine sont d'une importance cruciale pour une mise en oeuvre fiable des systèmes d'exploitation. Cet article commence par une vue d'ensemble de l'état actuel des connaissances en matière de ressources d'énergie éolienne. Il passe ensuite en revue plusieurs modèles de prédiction à court terme des vitesses des vents comprenant, en particulier, les approches chronologiques traditionnelles, ainsi que certains modèles plus raffinés fondés sur les modèles du type spatio‐temporel. Nous poursuivons avec une discussion de la précision des prévisions, en mettant l'accent sur le choix de fonctions de perte appropriées. Quelques défis nouveaux liés aux changements soudains des vents et aux énergies éoliennes offshores sont aussi présentés.
Using Complex Surveys to Estimate theL1‐Median of a Functional Variable: Application to Electricity Load Curves
Authors: Chaouch Mohamed , Goga Camelia 
Published: April 2012

Résumé Les courbes de profil moyen sont largement utilisées comme indicateurs du comportement de consommation d’électricité des clients. ÀÉlectricité de France (EDF), les profils de consommation de chaque catégorie de clients sont estimés par des courbes de charge moyennes. Malheureusement, la moyenne est très sensible à la présence des valeurs atypiques. Dans ce travail, nous proposons une alternative à la courbe moyenne: la L1‐médiane, qui est plus robuste. En présence de grandes bases de données de type courbes (les courbes de charge, par exemple), des approches par sondages sont une alternative intéressante pour estimer la courbe médiane en évitant le stockage de courbes. Nous proposons ici plusieurs stratégies d’échantillonnage et plusieurs estimateurs de la courbe médiane. Une comparaison entre les différentes stratégies est réalisée sur une population‐test. Nous développons une stratification basée sur les variables linéarisées qui améliore de façon substantielle l’estimateur par rapport au sondage aléatoire simple sans remise. Nous suggérons également un estimateur qui prend en compte l’information auxiliaire. Plusieurs directions de recherche sont envisagées.

Abstract.  1. Standardised transect counts of butterflies in old‐growth rainforests in different biogeographical regions are lacking. Such data are needed to mitigate the influence of methodological and environmental factors within and between sites and, ultimately, to discriminate between long‐term trends and short‐term stochastic changes in abundance and community composition.2. We compared butterfly assemblages using standardised Pollard Walks in the understory of closed‐canopy lowland tropical rainforests across three biogeographical regions: Barro Colorado Island (BCI), Panama; Khao Chong (KHC), Thailand; and Wanang (WAN), Papua New Guinea.3. The length and duration of transects, their spatial autocorrelation, and number of surveys per year represented important methodological factors that strongly influenced estimates of butterfly abundance. Of these, the effect of spatial autocorrelation was most difficult to mitigate across study sites.4. Butterfly abundance and faunal composition were best explained by air temperature, elevation, rainfall, wind velocity, and human disturbance at BCI and KHC. In the absence of weather data at WAN, duration of transects and number of forest gaps accounted for most of the explained variance, which was rather low in all cases (<33%).5. Adequate monitoring of the abundance of common butterflies was achieved at the 50 ha BCI plot, with three observers walking each of 10 transects of 500 m for 30 min each, during each of four surveys per year. These data may be standardised further after removing outliers of temperature and rainfall. Practical procedures are suggested to implement global monitoring of rainforest butterflies with Pollard Walks.
Whose Day Is It Anyway? St. Patrick's Day as a Contested Performance of National and Diasporic Irishness
Authors: Scully Marc 
Published: April 2012

AbstractOne of the more intriguing aspects of St. Patrick's Day celebrations as a nationalised ritual of a performed Irishness, both within and outside Ireland, is the extent to which it represents a dialogue between territorialised and diasporic expressions of Irish identity, and claims of belonging to Irishness. St. Patrick's Day celebrations in English cities are a particularly intriguing example of this contestation, due to the proximity of the two countries and the historical structural and cultural constraints on the public performance of Irish identity in England, as well as their more recent reinvention within celebratory multiculturalism. This article examines how debates around the authenticity of St. Patrick's Day parades in English cities are employed in the identity work of individual Irish people. In doing so, it provides insight on the tensions between Irishness as transnational, diasporic, and ethnic, as experienced in England.
Fresh Views on the Old Past: The Postage Stamps of the Mexican Bicentennial
Authors: Hoyo Henio 
Published: April 2012

AbstractThe year 2010 in Mexico marked both the 200th anniversary of the start of its independence movement and the 100th anniversary of its revolution. Besides several public events, a number of items including commemorative coins, banknotes, and stamps were produced to mark the occasion. This article analyses the postage stamps issued to commemorate the Mexican bicentennial. It does so by comparing these stamps with the ones issued for previous independence anniversaries, and then tracking changes and continuities in their messages. It is found that, on the one hand, the bicentennial postage stamps of Mexico promoted a particular narrative regarding the historical, territorial, and ethnic features of the Mexican independence process, which in many ways departs from previous, long‐established nationalist narratives. But on the other hand, bicentennial stamps also demonstrate the influence of traditional interpretations of the national past – particularly those related to the Partido Revolucionario Institucional's (Institutional Revolutionary Party, PRI) revolutionary nationalism doctrine – which are still being reproduced even after the 2000 democratic transition.

Published: April 2012

Abstract.Purpose:  To measure the concentration of cytokines in the aqueous humour of eyes with exudative age‐related macular degeneration (AMD).Methods:  The clinical interventional study included a study group of 18 patients with exudative AMD and a control group of 20 patients undergoing routine cataract surgery. Age did not vary significantly (p = 0.36) between study group (80.8 ± 6.4 years) and control group (77.0 ± 9.9 years), nor did gender (p = 0.75). During the interventions, aqueous humour samples were obtained, in which the concentration of cytokines was measured using a solid‐phase chemiluminescence immunoassay. Macular thickness was measured by optical coherence tomography (OCT).Results:  In the study group as compared to the control group, significantly higher concentrations were measured for epithelial growth factor (EGF) (p = 0.017), human growth factor (HGF) (p = 0.048), intercellular adhesion molecule‐1 (ICAM1) (p = 0.028), interleukin 12p40 (IL12p40) (p = 0.009), interleukin 1a2 (IL1a2) (p = 0.01), interleukin 3 (IL3) (p = 0.02), interleukin 6 (IL6) (p = 0.006), interleukin 8 (IL8) (p = 0.02), monocyte chemoattractant protein‐1 (MCP‐1) (p = 0.048), monokine induced by interferon gamma (MIG) (p = 0.016), matrix metalloproteinase 9 (MMP9) (p = 0.004) and plasminogen activator inhibitor 1 (PAI1) (p = 0.006). Macular thickness was significantly associated with the concentrations of EGF (p = 0.001), HGF (p = 0.02), ICAM1 (p = 0.001), interleukin 12p40 (p = 0.006), IL 1a2 (p = 0.002), MIG (p = 0.001), MMP9 (p < 0.001) and PAI1 (p = 0.01). Interleukin 6 and MCP‐1 showed significant associations with the height of retinal pigment epithelium detachment.Conclusions:  Numerous cytokines are associated with the presence and the amount of exudative AMD.

Published: April 2012

BackgroundThe pathophysiology of thrombus formation in canineIMHAand other diseases remains unclear. Antiphospholipid antibodies (aPL) are an important cause of thrombosis in humans and might cause thrombosis in dogs.HypothesisDogs withIMHA, spontaneous thrombosis, and hyperadrenocorticism will have increased levels ofaPLand lupus anticoagulants (LA), compared with healthy and sick dogs.AnimalsThreaPLwere measured in healthy controls (n = 40–45); sick dogs without thrombosis (n = 86);IMHA(n = 37); spontaneous thrombosis (ST, n = 11); and hyperadrenocorticism (n = 17). Four groups of dogs were also tested for the presence ofLA: healthy controls (n = 40); sick dogs without thrombosis (n = 13);IMHA(n = 13); and ST (n = 5).MethodsProspective cohort study. Dogs were tested foraPLby anELISAand forLAby the diluteRussell'sViper venom time (dRVVT). Median values were compared byKruskal–Wallis (aPL) orANOVA(LA), and an odds ratio for development of thrombosis in dogs positive foraPLwas calculated.ResultsaPLare uncommon in healthy dogs. A total of 13/86 sick dogs without thrombosis, 7/37 dogs withIMHA, 1/11 dogs withST, and 3/17 dogs withHACwere positive for protein binding‐dependentaPL. There was no significant difference in the number of dogs positive foraPLfor any of the study groups, and there was no increased risk for thrombosis in dogs positive foraPL. No dogs hadLA.ConclusionsOur preliminary research does not support a strong role foraPLfor the development of thrombosis in dogs withIMHAand other thombotic diseases, although future studies are warranted.

Published: April 2012

BackgroundCongestive heart failure (CHF) is associated with endothelial dysfunction in people and in dogs with experimentally induced CHF, but this is not well characterized in dogs with naturally occurring CHF.Hypothesis/ObjectivesTo evaluate endothelial function via assessment of reactive hyperemia (RH) in healthy dogs and dogs with CHF, and to assess for relationships with plasma biomarkers of vascular function and clinical markers of disease severity.AnimalsTwenty client‐owned animals with CHF due to myxomatous mitral valve disease (n = 15) or dilated cardiomyopathy (n = 5) and 17 healthy control dogs.MethodsProspective case‐controlled observational study. Dogs underwent blood sampling, echocardiography, and Doppler assessment of brachial artery velocity (VTI) at baseline and during reactive hyperemia (RH‐VTI). RH‐VTIs between control dogs and dogs with CHF were compared, and the relationships between RH‐VTI, clinical parameters, and plasma biomarkers were assessed.ResultsDogs with CHF (96.5 ± 51.7%) had an attenuated % increase in VTI during RH compared to healthy controls (134.8 ± 58.7%; P = .04). Increasing ISACHC class (R2 = 0.24; P = .004), plasma NT‐proBNP (R2 = 0.15; P = .03) and CRP (R2 = 0.2; P = .02) were associated with reduced RH‐VTI. Increased plasma CRP, NOx, and NT‐proBNP concentrations were found in dogs with CHF (P < .02 for all). No differences were detected in other plasma markers.Conclusions and Clinical ImportanceDogs with CHF have an attenuated RH response, and increased plasma CRP and NOx concentrations. Doppler assessment of RH velocity could represent a novel noninvasive method of evaluating endothelial function in the dog.

BackgroundDiagnosis of pituitary‐dependent hyperadrenocorticism (PDH) in cats is challenging because there is no specific diagnostic test.Hypothesis/ObjectiveThe determination of plasmaACTHprecursor (POMCand pro‐ACTH) concentration might facilitate the diagnosis ofPDHin cats. The aim of the study was to evaluate prospectively the plasma concentrations ofACTHprecursors in a small cohort of cats withPDHand to estimate the value of this approach for diagnosis.AnimalsFour groups of cats were included: group 1 (cats withPDH), group 2 (cats with diabetes mellitus but not hyperadrenocorticism (HAC)), group 3 (cats with diabetes mellitus and confirmed acromegaly but notHAC), and group 4 (healthy cats).MethodsPDHdiagnosis was based on clinical data, low‐dose dexamethasone suppression test (LDDST), and adrenal and pituitary gland computed tomography (CT) scan. For groups 2, 3, and 4, hyperadrenocorticism was excluded byLDDSTor urine cortisol:creatinine ratio (UCCR). An immunoluminometric assay was used to determine plasma concentrations ofACTHprecursors in the 4 groups of cats.ResultsGroup 1 contained 9 cats (enlarged pituitary gland in 7/9). PlasmaACTHprecursor concentrations ranged from <53 to >1010 pmol/L with 8/9 concentrations ≥229 pmol/L. Groups 2, 3, and 4 included 13, 7, and 13 cats, respectively. PlasmaACTHprecursor concentrations ranged from <53 to 96 pmol/L in group 2, <53 to 72 pmol/L in group 3, and <53 to 99 pmol/L in group 4.Conclusion and Clinical ImportanceHigh plasma concentration ofACTHprecursors in cats (>100 pmol/L) is highly suggestive ofPDH.

BackgroundCattle represent a reservoir forGiardiaandCryptosporidiumand may contaminate water sources.ObjectivesTo determine the distribution ofCryptosporidiumandGiardiaon dairy farms and in water bodies near the farms.Farms and Water SourcesTwenty dairy farms and 20 wells and 13 surface water samples associated with dairy farms.MethodsProportions of samples positive forCryptosporidiumorGiardiawere determined by a direct immunofluorescence assay. Fecal and water samples were taken at different times.ResultsThirty‐two (95%CI: 29–35%) and 14% (95%CI: 12–17%) of fecal samples, and 100 (95%CI: 96–100) and 55% (95%CI: 32–77%) of herds, were positive forGiardiaandCryptosporidium, respectively.Giardia duodenalisassemblageEwas detected in high proportions (90%) of fecal samples.Cryptosporidium bovispredominated (51%) in all cattle.C. andersonipredominated in adult cattle (53%), whereas the predominant species in animals < 2 months and 2–6 months wasC. bovis,respectively. Only calves < 2 months of age were positive forC. parvum. In 46% (95%CI: 19–75%) and 85% (95%CI: 55–98%) of surface water, concentrations ofGiardiacysts andCryptosporidiumoocysts were higher in downstream, than in upstream, locations of farms, whereas only 1 groundwater sample was positive forCryptosporidium.ConclusionsThis sample of dairy cattle was predominantly infected with nonzoonotic species and genotypes ofCryptosporidium,Giardia, or both. More studies are needed to determine if the presence ofGiardiaorCryptosporidiumin surface water was associated with shedding in animals from nearby farms.

Published: April 2012

ABSTRACT

The
in vitro
activity of ceftaroline, a recently introduced parenteral cephalosporin, was assessed versus 1,750 isolates of
Streptococcus pneumoniae
recovered from patients with a variety of pneumococcal infections in 43 U.S. medical centers during 2010-2011. Using a breakpoint of ≤0.5 μg/ml for susceptibility, all of the isolates were found to be susceptible to ceftaroline. Ceftaroline MICs were consistently 16-fold lower than ceftriaxone MICs. Among the isolates characterized in this investigation, 38.9% were found to be nonsusceptible to penicillin (oral penicillin breakpoints) and 9.1% were nonsusceptible to ceftriaxone (nonmeningitis breakpoints).

Published: April 2012

ABSTRACT

The treatment of Gram-negative infections is increasingly compromised by the spread of resistance. With few agents currently in development, clinicians are now considering the use of unorthodox combination therapies for multidrug-resistant strains. Here we assessed the
in vitro
activity of the novel lipoglycopeptide telavancin (TLV) when combined with colistin (COL) versus 13 Gram-negative type strains and 66 clinical isolates. Marked synergy was observed in either checkerboard (fractional inhibitory concentration index [FICI], <0.5; susceptibility breakpoint index [SBPI], >2) or time-kill assays (>2-log reduction in viable counts compared with starting inocula at 24 h) versus the majority of COL-susceptible enterobacteria,
Stenotrophomonas maltophilia
, and
Acinetobacter baumannii
isolates, but only limited effects were seen against
Pseudomonas aeruginosa
or strains with COL resistance. Using an Etest/agar dilution method, the activity of TLV was potentiated by relatively low concentrations of COL (0.25 to 0.75 μg/ml), reducing the MIC of TLV from >32 μg/ml to ≤1 μg/ml for 35% of the clinical isolates. This provides further evidence that glycopeptide-polymyxin combinations may be a useful therapeutic option in the treatment of Gram-negative infections.
“
tet
(U)” Is Not a Tetracycline Resistance Determinant
Authors: Caryl Jamie A. , Cox Georgina , Trimble Stefan , O'Neill Alex J. 
Published: April 2012

ABSTRACT

The enterococcal plasmid pKQ10 has been reported to carry a poorly characterized tetracycline resistance determinant designated
tet
(U). However, in a series of studies intended to further characterize this determinant, we have been unable to substantiate the claim that
tet
(U) confers resistance to tetracyclines. In line with these results, bioinformatic analysis provides compelling evidence that “
tet
(U)” is in fact the misannotated 3′ end of a gene encoding a rolling-circle replication initiator (Rep) protein.

Published: April 2012

ABSTRACTIn developing countries, one-third of reactive arthritis (ReA) cases are associated withSalmonellaenterocolitis; nevertheless, there is no animal model for studying this pathology. Here we induced a self-limitingSalmonella entericaserovar Enteritidis enterocolitis in mice to analyze the onset of ReA. BALB/c mice received orally 20 μg of streptomycin 24 h before intragastric inoculation of a low dose (3 × 103to 4 × 103CFU) ofS. Enteritidis. In response toSalmonellainfection, a 30-fold increase in the expression of interleukin-17 (IL-17), measured by quantitative PCR, was observed in mesenteric lymph nodes 5 days postinfection. At this time synovitis was already evident, and concomitantly, a significant increase in joint tumor necrosis factor alpha (TNF-α) was detected by enzyme-linked immunosorbent assay (ELISA). The early development of joint lesions was accompanied by an increased expression of IL-17 in inguinal and popliteal lymph nodes. Infection with 107CFU of an isogenic ΔinvGmutant bearing a defective type III secretion system ofSalmonellaencoded in the pathogenicity island 1 apparatus (TTSS-1) induced enterocolitis histologically similar to that triggered by the wild-type strain. Interestingly, despite the higher infective dose used, the mutant did not trigger intestinal IL-17. Moreover, no synovitis was observed in mice suffering ΔinvGenterocolitis. Neutralization of IL-17 in mice infected withS. Enteritidis prevented both synovitis and the increment of TNF-α in the joints, suggesting that IL-17 participates in the generation ofSalmonella-induced ReA through the induction of TNF-α in the joints.

The Prologue of Iphigenia Aulidensis Reconsidered
Authors: Pietruczuk Katarzyna 
Published: April 2012

AbstractThe authenticity of the prologue ofIphigenia Aulidensis, as it is preserved in the MSS, has been questioned by many scholars. Apart from its metrical form and style (which are discussed only briefly here), the students of the play point out two crucial problems concerning the internal consistency of the plot. First, lines 124-32 become superfluous when they are confronted with lines 106-7. Secondly, there is an inconsistency between the passages implying that Calchas’ oracle and the plan of luring Iphigenia to Aulis was known only to Calchas, Odysseus, Menelaus and Agamemnon and those according to which the whole Greek army was aware of Agamemnon’s ruse. The present discussion aims to show that the simplest way to remove both inconsistencies is to exclude as interpolated lines 105-10, without the necessity either of deleting the subsequent passage (lines 111-14), suspected by many scholars, or of questioning the authenticity of the prologue as a whole. Additionally, it is suggested that the interpolator was probably thinking of E.IT15-25 and 521-49.
