    Full Text Available The aim of this work was to isolate, clone and characterize the iron uptake gene iutA from avian pathogenic E. coli (APEC. The iutA gene was isolated from the strain APEC 9, serotype O2:H9, which was cloned in the expression vector pET101/D-TOPO. The gene of 2.2 Kb was sequenced (AY602767, which showed high similarity to the iutA gene from three plasmids, two from APEC, pAPEC-02-ColV (AY545598.4 and pTJ100 (AY553855.1, and one from a human invasive E. coli strain, the pColV K30. The recombinant protein IutA was over expressed in E. coli BL21(DE-3 and was solubilized with urea and purified by Ni-NTA column. This method produced a relatively high yield of r-IutA of approximately 74kDa, which was used to produce the antibody anti-IutA. This anti-IutA reacted with the protein r-IutA and native IutA of APEC 9, as demonstrated by Western blot, showing that the r-IutA conserved epitopes and its antigenicity was preserved. The anti-IutA IgY was able to inhibit the IutA biological activity, inhibiting the sensitivity to cloacin DF13 of APEC9. However, it did not inhibit the growth of APEC9 in M9 and did not protect the chickens inoculated with the APEC, suggesting that the APEC possessed another iron acquisition mechanism distinct of aerobactin.A proteína de membrane externa IutA (iron uptake transport é o receptor para aerobactina férrica, um fator de virulência encontrado mais frequentemente entre as amostras de E. coli pathogênicas para aves (APEC do que entre os isolados fecais de aves saudáveis.

  7. Che genere di diritto?

    Full Text Available Il recente decreto legge sul femminicidio nasce in un clima, soprattutto mediatico, nel quale la violenza sulle donne viene letta come “emergenza”. Questa chiave di lettura del fenomeno presenta alcuni rischi: in primo luogo, quello di riproporre un modello di intervento pubblico centrato soprattutto sull’approccio repressivo. Il decreto assegna, infatti, una valenza residuale ad una strategia di sostegno delle azioni di prevenzione e di assistenza delle vittime di violenza, al momento rinviate ad un “Piano d'azione straordinario” per il quale non viene previsto alcun finanziamento. E’ tempo di uscire dalla logica emergenziale: la questione della violenza di genere non è solo problema di ordine pubblico. E’ un fenomeno che colpisce al cuore la riscrittura delle regole sulla convivenza tra i generi avviata nel secolo scorso. Ciò che serve è un nuovo momento di elaborazione delle teorie e delle prassi delle donne sul ruolo del sistema giuridico e sulle forme più adeguate per garantire la libertà femminile.

  17. Phosphate flow between hybrid histidine kinases CheA₃ and CheS₃ controls Rhodospirillum centenum cyst formation.

    Directory of Open Access Journals (Sweden)

    Kuang He

    Full Text Available Genomic and genetic analyses have demonstrated that many species contain multiple chemotaxis-like signal transduction cascades that likely control processes other than chemotaxis. The Che₃ signal transduction cascade from Rhodospirillum centenum is one such example that regulates development of dormant cysts. This Che-like cascade contains two hybrid response regulator-histidine kinases, CheA₃ and CheS₃, and a single-domain response regulator CheY₃. We demonstrate that cheS₃ is epistatic to cheA₃ and that only CheS₃∼P can phosphorylate CheY₃. We further show that CheA₃ derepresses cyst formation by phosphorylating a CheS₃ receiver domain. These results demonstrate that the flow of phosphate as defined by the paradigm E. coli chemotaxis cascade does not necessarily hold true for non-chemotactic Che-like signal transduction cascades.

  20. Identification of an anchor residue for CheA-CheY interactions in the chemotaxis system of Escherichia coli.

    Transfer of a phosphoryl group from autophosphorylated CheA (P-CheA) to CheY is an important step in the bacterial chemotaxis signal transduction pathway. This reaction involves CheY (i) binding to the P2 domain of P-CheA and then (ii) acquiring the phosphoryl group from the P1 domain. Crystal structures indicated numerous side chain interactions at the CheY-P2 binding interface. To investigate the individual contributions of the P2 side chains involved in these contacts, we analyzed the effects of eight alanine substitution mutations on CheA-CheY binding interactions. An F214A substitution in P2 caused ∼1,000-fold reduction in CheA-CheY binding affinity, while Ala substitutions at other P2 positions had small effects (E171A, E178A, and I216A) or no detectable effects (H181A, D202A, D207A, and C213A) on binding affinity. These results are discussed in relation to previous in silico predictions of hot-spot and anchor positions at the CheA-CheY interface. We also investigated the consequences of these mutations for chemotaxis signal transduction in living cells. CheA(F214A) was defective in mediating localization of CheY-YFP to the large clusters of signaling proteins that form at the poles of Escherichia coli cells, while the other CheA variants did not differ from wild-type (wt) CheA (CheA(wt)) in this regard. In our set of mutants, only CheA(F214A) exhibited a markedly diminished ability to support chemotaxis in motility agar assays. Surprisingly, however, in FRET assays that monitored receptor-regulated production of phospho-CheY, CheA(F214A) (and each of the other Ala substitution mutants) performed just as well as CheA(wt). Overall, our findings indicate that F214 serves as an anchor residue at the CheA-CheY interface and makes an important contribution to the binding energy in vitro and in vivo; however, loss of this contribution does not have a large negative effect on the overall ability of the signaling pathway to modulate P-CheY levels in response to

  1. The importance of the interaction of CheD with CheC and the chemoreceptors compared to its enzymatic activity during chemotaxis in Bacillus subtilis.

    Directory of Open Access Journals (Sweden)

    Wei Yuan

    Full Text Available Bacillus subtilis use three systems for adaptation during chemotaxis. One of these systems involves two interacting proteins, CheC and CheD. CheD binds to the receptors and increases their ability to activate the CheA kinase. CheD also binds CheC, and the strength of this interaction is increased by phosphorylated CheY. CheC is believed to control the binding of CheD to the receptors in response to the levels of phosphorylated CheY. In addition to their role in adaptation, CheC and CheD also have separate enzymatic functions. CheC is a CheY phosphatase and CheD is a receptor deamidase. Previously, we demonstrated that CheC's phosphatase activity plays a minor role in chemotaxis whereas its ability to bind CheD plays a major one. In the present study, we demonstrate that CheD's deamidase activity also plays a minor role in chemotaxis whereas its ability to bind CheC plays a major one. In addition, we quantified the interaction between CheC and CheD using surface plasmon resonance. These results suggest that the most important features of CheC and CheD are not their enzymatic activities but rather their roles in adaptation.

    Attention deficit hyperactivity disorder (ADHD) is a childhood onset neuropsychiatric disorder characterized by inattention, hyperactivity and impulsivity. ADHD is related to several co-morbidities, such as opposition defiant disorder, conduct disorder, mood and anxiety disturbances, as well as tics and Tourette's syndrome. The objective of this report is to shed an alternative light on the personality of Ernesto "Che" Guevara, discussing whether he might have had ADHD. Several published biographies of Che Guevara were reviewed. Established ADHD criteria (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition), were used as a framework to evaluate Che's behaviour. In addition, we compared the main features of Che's reported behaviour to the set of abnormalities leading to the diagnosis of ADHD in adults proposed by Wender and colleagues and known as the UTAH ADHD criteria. Analysis of the most renowned biographies of Ernesto "Che" Guevara suggests that he may have had ADHD.

    2014-04-01

    Full Text Available Cambiare la cultura significa cambiare il modo di pensare, con una consapevolezza e una conoscenza che permetta di rintracciare stereotipi e ruoli nascosti nelle pieghe profonde della società, e così tanto radicati nel nostro modo di essere, da risultare quasi invisibili. Stereotipi che sono parte integrante del nostro modo di vivere, e che pongono uomini e donne su piani di superiorità e subalternità in base al sesso, e senza alcuna altra motivazione, condizionando pesantemente le relazioni umane attraverso un pregiudizio. Una discriminazione che è già una forma di violenza che considera la donna come un oggetto da conquistare, possedere, controllare, e non un soggetto. La violenza maschile contro le donne non è un fenomeno né nuovo né solo italiano. E se il problema è strutturale e culturale, l’informazione e la narrazione mediatica di questa violenza, diventa uno dei fattori principali per il cambiamento.

    总结了本项目组近年来关于化学置换镀铜(合金)的研究成果与进展,提出了置换镀 的电化学沉积机理:通过选择添加剂可控制置换反应的沉积速度和电极电位,避免高过电位 时三维晶核的出现与疏松沉积物的形成,使置换镀的阴极过程沿着类似正常的电沉积的机理 进行,从而得到结合强度较好的置换沉积层.置换镀沉积速度快,工艺过程简单,而且具有 较高的结合强度和抗腐蚀性能,是CO2气体保护焊丝,轮胎钢丝及其他钢丝进行镀铜、镀 锡青铜的理想工艺.%On the basis of our recent study and progress about copperalloy plating , a theory of electrochemical deposition by chemical displaceplating is provid ed. In the presence of proper additives, not only can the deposition velocity of displaceplating and electrode potential be controlled, also the threedimens ion crystal and loose deposition can be avoided. Thus the cathodic process of displacement plating can succeed as normal electrodeposit. Furthermore, high st reng th displaceplating layer can be made. The technology is ideal and satisfactory to plate copper for CO2 gas welding wire, tyrewire, othe r wir es and tinbronze because of its high speed deposition, simple process, higher composition power and rustproof ability.

    Multiple sets of chemotaxis genes including three cheA homologs were identified in the genome sequence of the anaerobic bacterium Desulfovibrio vulgaris Hildenborough. Each CheA is a histidine kinase (HK) and part of a two component signal transduction system. Knock out mutants in the three cheA genes were created using single cross-over homologous recombination insertion. We studied the phenotypes of the cheA mutants in detail and discovered that ?cheA-3 has a non swarming/swimming phenotype both in the soft agar plates and Palleroni chamber assays. CheA-3 shows similarity to the Shewanella oneidensis CheA-3 and the Vibrio cholerae CheA-2 that are responsible for chemotaxis in the respective organisms. We did not find any morphological or structural differences between the three Delta cheA mutants and the wild type cells in electron microscopy. Our results from these studies are presented.

    P fimbriae, enabling adherence to colonic and urinary epithelium, and aerobactin, an iron sequestering system, are both colonization factors in the human colon and virulence factors for urinary tract infection. The colonic microbiota is suggested to be a site suitable for the transfer of antibiotic resistance genes. We investigated whether phenotypic resistance to antibiotics in commensal and uropathogenic Escherichia coli from infants and young children is associated with carriage of virulence genes and to phylogenetic group origin and, in the case of fecal strains, to persistence in the gut and fecal population levels. The commensal strains (n = 272) were derived from a birth cohort study, while the urinary isolates (n = 205) were derived from outpatient clinics. Each strain was assessed for phenotypic antibiotic resistance and for carriage of virulence genes (fimA, papC, sfaD/E, hlyA, iutA, kfiC, and neuB), phylogenetic group (A, B1, B2, or D), and markers of particular virulent clones (CGA-D-ST69, O15:H1-D-ST393, and O25b:H4-B2-ST131). Resistance to ampicillin, tetracycline, and trimethoprim was most prevalent. Multivariate analysis showed that resistance to any antibiotic was significantly associated with carriage of genes encoding P fimbriae (papC) and aerobactin (iutA), and a phylogenetic group D origin. Neither fecal population numbers nor the capacity for long-term persistence in the gut were related to antibiotic resistance among fecal strains. Our study confirms the importance of phylogenetic group D origin for antibiotic resistance in E. coli and identifies the virulence genes papC and iutA as determinants of antibiotic resistance. The reason for the latter association is currently unclear.

    A few months ago (see Echo 175) we announced the opening, at the end of August, of a crèche at the CERN Staff Association’s nursery school. After a very active summer, where a new floor was added to the canteen building, the new school year started in excellent conditions and, as expected, the new crèche opened on Tuesday 27 August. This crèche, with 13 full-time equivalent places, can accept 18 children aged between three months and two years in a space fully refitted to care for the little ones. A specially designed space for breastfeeding helps mothers working on the site to respect their baby's rhythm. In compliance with the standards of supervision in the canton of Geneva six educators take care of the children in shifts. This new space is fully integrated in the nursery school so that now the crèche, Kindergarten and school of the CERN Staff Association can welcome children aged from three months to six years, from Monday to Friday, and...

  18. Changing cellular location of CheZ predicted by molecular simulations.

    Directory of Open Access Journals (Sweden)

    2006-04-01

    Full Text Available In the chemotaxis pathway of the bacterium Escherichia coli, signals are carried from a cluster of receptors to the flagellar motors by the diffusion of the protein CheY-phosphate (CheYp through the cytoplasm. A second protein, CheZ, which promotes dephosphorylation of CheYp, partially colocalizes with receptors in the plasma membrane. CheZ is normally dimeric in solution but has been suggested to associate into highly active oligomers in the presence of CheYp. A model is presented here and supported by Brownian dynamics simulations, which accounts for these and other experimental data: A minority component of the receptor cluster (dimers of CheA(short nucleates CheZ oligomerization and CheZ molecules move from the cytoplasm to a bound state at the receptor cluster depending on the current level of cellular stimulation. The corresponding simulations suggest that dynamic CheZ localization will sharpen cellular responses to chemoeffectors, increase the range of detectable ligand concentrations, and make adaptation more precise and robust. The localization and activation of CheZ constitute a negative feedback loop that provides a second tier of adaptation to the system. Subtle adjustments of this kind are likely to be found in many other signaling pathways.

    The transcriptional cofactor Che-1 is an RNA polymerase II (Pol II) which is involved in tumorigenesis, such as breast cancer and multiple myeloma. Che-1 can also regulate mutant p53 expression, which plays roles in many types of cancer. In this study, we aimed to investigate the effects and specific mechanism of Che-1 in the regulation of osteosarcoma (OS) cell growth. We found that Che-1 is highly expressed in several kinds of OS cells compared with osteoblast hFOB1.19 cells. MTT and flow cytometry assays showed that Che-1 depletion by siRNA markedly suppressed MG-63 and U2OS cell proliferation and promoted apoptosis. The chromatin immunoprecipitation (ChIP) assay verified the presence of Che-1 on the p53 promoter in MG-63 and U2OS cells carrying mutant p53. Further studies showed that Che-1 depletion inhibited mutant p53 expression. Notably, our study showed that the loss of Che-1 inhibits proliferation and promotes apoptosis in MG-63 cells by decreasing the level of mutant p53. Therefore, these findings open the possibility that silencing of Che-1 will have therapeutic benefit in OS. - Highlights: • Che-1 is highly expressed in several kinds of OS cells. • Che-1 depletion suppressed MG-63 and U2OS cell growth. • Che-1 is existed in the p53 promoter in MG-63 and U2OS cells. • Che-1 depletion inhibited mutant p53 expression. • Che-1 depletion inhibits cell growth by decreasing the level of mutant p53.

    Homology models of the E. coli and T. maritima chemotaxis protein CheW were constructed to assess the quality of structural predictions and their applicability in chemotaxis research: i) a model of E. coli CheW was constructed using the T. maritima CheW NMR structure as a template, and ii) a model of T. maritima CheW was constructed using the E. coli CheW NMR structure as a template. The conformational space accessible to the homology models and to the NMR structures was investigated using molecular dynamics and Monte Carlo simulations. The results show that even though static homology models of CheW may be partially structurally different from their corresponding experimentally determined structures, the conformational space they can access through their dynamic variations can be similar, for specific regions of the protein, to that of the experimental NMR structures. When CheW homology models are allowed to explore their local accessible conformational space, modeling can provide a rational path to predicting CheW interactions with the MCP and CheA proteins of the chemotaxis complex. Homology models of CheW (and potentially, of other chemotaxis proteins) should be seen as snapshots of an otherwise larger ensemble of accessible conformational space.

    Transcriptional regulation is a key process in the formation of long-term memories. Che-1 is a protein involved in the regulation of gene transcription that has recently been proved to bind the transcription factor NF-κB, which is known to be involved in many memory-related molecular events. This evidence prompted us to investigate the putative role of Che-1 in memory processes. For this study we newly generated a line of Che-1(+/-) heterozygous mice. Che-1 homozygous KO mouse is lethal during development, but Che-1(+/-) heterozygous mouse is normal in its general anatomical and physiological characteristics. We analyzed the behavioral characteristic and memory performance of Che-1(+/-) mice in two NF-κB dependent types of memory. We found that Che-1(+/-) mice show similar locomotor activity and thigmotactic behavior than wild type (WT) mice in an open field. In a similar way, no differences were found in anxiety-like behavior between Che-1(+/-) and WT mice in an elevated plus maze as well as in fear response in a contextual fear conditioning (CFC) and object exploration in a novel object recognition (NOR) task. No differences were found between WT and Che-1(+/-) mice performance in CFC training and when tested at 24h or 7days after training. Similar performance was found between groups in NOR task, both in training and 24h testing performance. However, we found that object recognition memory persistence at 7days was impaired in Che-1(+/-) heterozygous mice. This is the first evidence showing that Che-1 is involved in memory processes.

    Myxococcus xanthus co-ordinates cell movement during its complex life cycle using multiple chemotaxis-like signal transduction pathways. These pathways regulate both type IV pilus-mediated social (S) motility and adventurous (A) motility. During a search for new chemoreceptors, we identified the che4 operon, which encodes homologues to a MCP (methyl-accepting chemotaxis protein), two CheWs, a hybrid CheA-CheY, a response regulator and a CheR. Deletion of the che4 operon did not cause swarming or developmental defects in either the wild-type (A(+)S(+)) strain or in a strain sustaining only A motility (A(+)S(-)). However, in a strain displaying only S motility (A(-)S(+)), deletion of the che4 operon or the gene encoding the response regulator, cheY4, caused enhanced vegetative swarming and prevented aggregation and sporulation. In contrast, deletion of mcp4 caused reduced vegetative swarming and enhanced development compared with the parent strain. Single-cell analysis of the motility of the A(-)S(+) parent strain revealed a previously unknown inverse correlation between velocity and reversal frequency. Thus, cells that moved at higher velocities showed a reduced reversal frequency. This co-ordination of reversal frequency and velocity was lost in the mcp4 and cheY4 mutants. The structural components of the S motility apparatus were unaffected in the che4 mutants, suggesting that the Che4 system affects reversal frequency of cells by modulating the function of the type IV pilus.

    2015-04-01

    Full Text Available The transcriptional cofactor Che-1/AATF is currently emerging as an important component of the DNA damage response machinery, the complex signaling network that maintains genome integrity and prevents tumorigenesis. Moreover this protein is involved in a wide range of cellular pathways, regulating proliferation and survival in both physiological and pathological conditions. Notably, some evidence indicates that dysregulation of Che-1/AATF levels are associated with the transformation process and elevated levels of Che-1/AATF are required for tumor cell survival. It is for these reasons that Che-1/AATF has been regarded as an attractive, still theoretical, therapeutic target for cancer treatments. In this review, we will provide an updated overview of Che-1/AATF activities, from transcriptional regulation to DNA damage response.

  9. The anti-apoptotic factor Che-1/AATF links transcriptional regulation, cell cycle control, and DNA damage response

    Directory of Open Access Journals (Sweden)

    Fanciulli Maurizio

    2007-07-01

    Full Text Available Abstract Che-1 is a RNA polymerase II binding protein involved in the transcriptional regulation of E2F target genes and in cell proliferation. Recently, it has been shown that Che-1 accumulates in cells responding to genotoxic agents such as Doxorubicin and ionizing radiation. The DNA damage-activated checkpoint kinases ATM and Chk2 interact with and phosphorylate Che-1, enhancing its accumulation and stability, and promoting Che-1-mediated transcription of p53-responsive genes and of p53 itself, as evidenced by microarray analysis. This transcriptional response is suppressed by expression of a Che-1 mutant lacking ATM and Chk2 phosphorylation amino acid residues, or by depletion of Che-1 by RNA silencing. In addition, chromatin immunoprecipitation analysis has shown that Che-1 is released from E2F target genes and recruited to the p21 and p53 promoters after DNA damage. Che-1 contributes to the maintenance of the G2/M checkpoint in response to genotoxic stress. These findings identify a new mechanism by which the checkpoint kinases regulate, via the novel effector Che-1, the p53 pathway. Lastly, increasing evidence suggests that Che-1 may be involved in apoptotic signaling in neural tissues. In cortical neurons, Che-1 exhibits anti-apoptotic activity, protecting cells from neuronal damage induced by amyloid β-peptide. In cerebellar granule neurons, Che-1 interacts with Tau in the cytoplasmic compartment and this interaction is modulated during neuronal apoptosis. Finally, Che-1 directly interacts with the neuronal cell-death inducer "NRAGE" which downregulates endogenous Che-1 by targeting it for proteasome-dependent degradation. These findings identify Che-1 as a novel cytoprotective factor against apoptotic insults and suggest that Che-1 may represent a potential target for therapeutic application.

    2007-01-01

    Rhodobacter sphaeroides expresses two different flagellar systems, a subpolar flagellum (fla1) and multiple polar flagella (fla2). These structures are encoded by different sets of flagellar genes. The chemotactic control of the subpolar flagellum (fla1) is mediated by three of the six different CheY proteins (CheY6, CheY4, or CheY3). We show evidence that CheY1, CheY2, and CheY5 control the chemotactic behavior mediated by fla2 flagella and that RSP6099 encodes the fla2 FliM protein. PMID:17890312

    1995-10-01

    The genetic variability of butyrylcholinesterase, determined by the BCHE and CHE2 loci, was examined in nine Brazilian Indian groups. In addition, a search for the presence of the BCHE*F allele was also performed in eight other Brazilian Indian samples and in five admixed (black-Indian-white) rural Amazonian communities previously studied for the CHE2 locus and the BCHE*A allele. In the Indian populations the frequency of the BCHE*F allele varied from 0 to 7.1% +/- 3.4 and the frequency of the CHE2 C5+ phenotype ranged from 1.4% +/- 1.4 to 45.9% +/- 3.8. This study seems to be the first to report the presence of the BCHE*F allele in native Americans. The BCHE*A allele appeared in one Indian group (1.4% +/- 1.0), and we suggest that its existence in this tribe and in other native Americans can be explained by gene flow from white populations. Gene flow may also be the reason for the occurrence of the BCHE*F allele in Brazilian Indians, whereas the CHE2*C5+ allele may have been present in the paleo-Indians. The distributions of both the BCHE*F allele and the CHE2 C5+ phenotype in Brazilian Indians seem to be the result of the action of random genetic drift.

  16. The Azospirillum brasilense Che1 chemotaxis pathway controls swimming velocity, which affects transient cell-to-cell clumping.

    Bible, Amber; Russell, Matthew H; Alexandre, Gladys

    2012-07-01

    The Che1 chemotaxis-like pathway of Azospirillum brasilense contributes to chemotaxis and aerotaxis, and it has also been found to contribute to regulating changes in cell surface adhesive properties that affect the propensity of cells to clump and to flocculate. The exact contribution of Che1 to the control of chemotaxis and flocculation in A. brasilense remains poorly understood. Here, we show that Che1 affects reversible cell-to-cell clumping, a cellular behavior in which motile cells transiently interact by adhering to one another at their nonflagellated poles before swimming apart. Clumping precedes and is required for flocculation, and both processes appear to be independently regulated. The phenotypes of a ΔaerC receptor mutant and of mutant strains lacking cheA1, cheY1, cheB1, or cheR1 (alone or in combination) or with che1 deleted show that Che1 directly mediates changes in the flagellar swimming velocity and that this behavior directly modulates the transient nature of clumping. Our results also suggest that an additional receptor(s) and signaling pathway(s) are implicated in mediating other Che1-independent changes in clumping identified in the present study. Transient clumping precedes the transition to stable clump formation, which involves the production of specific extracellular polysaccharides (EPS); however, production of these clumping-specific EPS is not directly controlled by Che1 activity. Che1-dependent clumping may antagonize motility and prevent chemotaxis, thereby maintaining cells in a metabolically favorable niche.

    We here report the sequence and functional analysis of cstB of Azospirillum brasilense Sp7. The predicted cstB contains C-terminal two PAS domains and N-terminal part which has similarity with CheB-CheR fusion protein. cstB mutants had reduced swarming ability compared to that of A. brasilense wild-type strain, implying that cstB was involved in chemotaxis in A. brasilense. A microscopic analysis revealed that cstB mutants developed mature cyst cells more quickly than wild type, indicating that cstB is involved in cyst formation. cstB mutants were affected in colony morphology and the production of exopolysaccharides (EPS) which are essential for A. brasilense cells to differentiate into cyst-like forms. These observations suggested that cstB was a multi-effector involved in cyst development and chemotaxis in A. brasilense.

    Nelle parole della grande giornalista recentemente scomparsa, la documentata narrazione della storia di Bruno Pontecorvo, fisico nucleare di fama mondiale che, nel pieno della Guerra fredda, scelse di abbandonare l'Occidente e di lavorare e vivere nell'Unione Sovietica. Grazie alla capacità della Mafai nel ricostruire gli eventi cruciali della vita di Pontecorvo in un nuovo quadro rivelatore, "Il lungo freddo" non offre solo un'inedita prospettiva sulla drammatica corsa alla bomba atomica - dalle decisive scoperte del Progetto Manhattan alla tragica esplosione di Hiroshima, dalla prima atomica sovietica alla bomba all'idrogeno - ma rappresenta soprattutto la memoria collettiva di una generazione che ha posto la politica al centro delle proprie scelte di vita. E svela i drammi umani di un conflitto che per più di quarant'anni ha diviso il mondo.

Alvisi’s text is analysed in comparison with other fictional and journalistic representations of Ilaria Alpi, while Non dirmi che hai paura is examined through what Catozzella considers the two constitutive dimensions of the novel: documentation and identification. Drawing on Stefano Jossa’s reflections on the construction of literary heroes, the article challenges Alvisi’s and Catozzella’s claims that they represent ‘true stories’. The article also argues that the main characters of these literary works are portrayed as heroines and role models for the emancipation of Muslim women.

    For many years, the Staff Association has supported the demand for the creation of a crèche for the children of CERN staff. Several studies have been carried out without leading to a concrete plan. The fact that the CERN population is getting younger and the shortage of local facilities have led to a more urgent demand for this type of social service over the past few years. Furthermore, the Equal Opportunities Panel had already recommended that crèche places be made available.

    Ben prima della luce, a un decimillesimo di secondo dal Big Bang, i neutrini sono apparsi nell'universo. Dopo un secondo il brodo primordiale si era raffreddato abbastanza da consentire loro di muoversi liberi e ancora oggi, dopo quasi quattordici miliardi di anni, sono numerosissimi. Ma che cosa sono i neutrini? Elusivi come fantasmi, camaleontici, viaggiano indenni attraverso la materia arrivando dritti sino a noi dagli angoli più remoti e nascosti dell'universo. Per saperne di più seguiremo i fisici che li studiano in laboratori sotterranei o in luoghi estremi come i ghiacciai polari o le profondità marine.

    For the past two decades, the use of genetically fused fluorescent proteins (FPs) has greatly contributed to the study of chemotactic signalling in Escherichia coli including the activation of the response regulator protein CheY and its interaction with the flagellar motor. However, this approach suffers from a number of limitations, both biological and biophysical: for example, not all fusions are fully functional when fused to a bulky FP, which can have a similar molecular weight to its fused counterpart; they may interfere with the native interactions of the protein and the chromophores of FPs have low brightness and photostability and fast photobleaching rates. A recently developed technique for the electroporation of fluorescently labelled proteins in live bacteria has enabled us to bypass these limitations and study the in vivo behaviour of CheY at the single-molecule level. Here we show that purified CheY proteins labelled with organic dyes can be internalized into E. coli cells in controllable concentrations and imaged with video fluorescence microscopy. The use of this approach is illustrated by showing single CheY molecules diffusing within cells and interacting with the sensory clusters and the flagellar motors in real time. This article is part of the themed issue ‘The new bacteriology’. PMID:27672145

    Chemotactic methyltransferase, CheR catalyse methylation of specific glutamate residues in the cytoplasmic domain of methyl-accepting chemotactic protein receptors (MCPRs). The methylation of MCPRs is essential for the chemical sensing and chemotactic bacterial mobility towards favorable chemicals or away from unfavorable ones. In this study, crystal structure of B. subtilis CheR (BsCheR) in complex with S-adenosyl-l-homocysteine (SAH) has been determined to 1.8Å resolution. This is the first report of crystal structure belonging to the pentapeptide-independent CheR (PICheR) class. Till date, only one crystal structure of CheR from S. typhimurium (StCheR) belonging to pentapeptide-dependent CheR (PDCheR) class is available. Structural analysis of BsCheR reveals a helix-X-helix motif (HXH) with Asp53 as the linker residue in the N-terminal domain. The key structural features of the PDCheR β-subdomain involved in the formation of a tight complex with the pentapeptide binding motif in MCPRs were found to be absent in the structure of BsCheR. Additionally, isothermal titration calorimetry (ITC) experiments were performed to investigate S-adenosyl-(l)-methionine (SAM) binding affinity and KD was determined to be 0.32mM. The structure of BsCheR reveals that mostly residues of the large C-terminal domain contribute to SAH binding, with contributions of few residues from the linker region and the N-terminal domain. Structural investigations and sequence analysis carried out in this study provide critical insights into the distinct receptor recognition mechanism of the PDCheR and PICheR methyltransferase classes.

  8. Drosophila CheB proteins involved in gustatory detection of pheromones are related to a human neurodegeneration factor.

    2010-01-01

    The Drosophila CheBs proteins are expressed in a variety of sexually dimorphic subsets of taste hairs, some of which have been directly implicated in pheromone detection. Their remarkable collection of expression patterns suggests that CheBs have specialized roles in gustatory detection of pheromones. Indeed, mutations in the CheB42a gene specifically alter male response to female-specific cuticular hydrocarbons. Furthermore, CheBs belong to the large ML (MD-2-like) superfamily of lipid-binding proteins and share amino acids with an essential role in the function of human GM2-activator protein (GM2-AP), a protein whose absence results in neurodegeneration and death. As GM2-AP binds specifically to the GM2 ganglioside, we have proposed that CheB42a and other CheBs function by interacting directly with the lipid-like cuticular hydrocarbons of Drosophila melanogaster and modulating their detection by transmembrane receptors. Here I review the current knowledge of the CheB family and discuss possible models for their function.

    Il volume raccoglie, oltre al testo della lezione del 1854 che dà il titolo all'opera, alcuni scritti di carattere scientifico e filosofico di Riemann. A saggi di argomento scientifico si affiancano scritti di argomento più direttamente metodologico. La concezione della scienza che ci viene offerta da questi scritti è assai significativa del personaggio e della sua epoca. Per Riemann la matematica non è un mero strumento esteriore da applicare, appunto dall'esterno, ai fenomeni. Al contrario, essa consente di spingersi con il rigore necessario oltre alla superficie dei fenomeni e di penetrare sempre più a fondo nella realtà, nell'ottica di un sistema unitario e quasi metafisico del sapere scientifico.

  11. Site-specific and synergistic stimulation of methylation on the bacterial chemotaxis receptor Tsr by serine and CheW

    Directory of Open Access Journals (Sweden)

    Weis Robert M

    2005-03-01

    Full Text Available Abstract Background Specific glutamates in the methyl-accepting chemotaxis proteins (MCPs of Escherichia coli are modified during sensory adaptation. Attractants that bind to MCPs are known to increase the rate of receptor modification, as with serine and the serine receptor (Tsr, which contributes to an increase in the steady-state (adapted methylation level. However, MCPs form ternary complexes with two cytoplasmic signaling proteins, the kinase (CheA and an adaptor protein (CheW, but their influences on receptor methylation are unknown. Here, the influence of CheW on the rate of Tsr methylation has been studied to identify contributions to the process of adaptation. Results Methyl group incorporation was measured in a series of membrane samples in which the Tsr molecules were engineered to have one available methyl-accepting glutamate residue (297, 304, 311 or 493. The relative rates at these sites (0.14, 0.05, 0.05 and 1, respectively differed from those found previously for the aspartate receptor (Tar, which was in part due to sequence differences between Tar and Tsr near site four. The addition of CheW generated unexpectedly large and site-specific rate increases, equal to or larger than the increases produced by serine. The increases produced by serine and CheW (added separately were the largest at site one, ~3 and 6-fold, respectively, and the least at site four, no change and ~2-fold, respectively. The rate increases were even larger when serine and CheW were added together, larger than the sums of the increases produced by serine and CheW added separately (except site four. This resulted in substantially larger serine-stimulated increases when CheW was present. Also, CheW enhanced methylation rates when either two or all four sites were available. Conclusion The increase in the rate of receptor methylation upon CheW binding contributes significantly to the ligand specificity and kinetics of sensory adaptation. The synergistic effect of

    Since chemical shifts provide important and relatively accessible information about protein structure in solution, a Web server, CheShift-2, was developed for structure interrogation, based on a quantum mechanics database of {sup 13}C{sup {alpha}} chemical shifts. We report the application of CheShift-2 to a local inconsistency between two X-ray crystal structures (PDB IDs 1IKN and 1NFI) of the complex between the p65/p50 heterodimer of NF{kappa}B and its inhibitor I{kappa}B{alpha}. The availability of NMR resonance assignments that included the region of the inconsistency provided an opportunity for independent validation of the CheShift-2 server. Application of the server showed that the {sup 13}C{sup {alpha}} chemical shifts measured for the Gly270-Pro281 sequence close to the C-terminus of I{kappa}B{alpha} were unequivocally consistent with the backbone structure modeled in the 1IKN structure, and were inconsistent with the 1NFI structure. Previous NOE measurements had demonstrated that the position of a tryptophan ring in the region immediately N-terminal in this region was not consistent with either structure. Subsequent recalculation of the local structure in this region, based on the electron density of the deposited structure factors for 1IKN, confirmed that the local backbone structure was best modeled by 1IKN, but that the rotamer of Trp258 is consistent with the 1NFI structure, including the presence of a hydrogen bond between the ring N{epsilon}H of Trp258 and the backbone carbonyl group of Gln278. The consensus between all of these measures suggests that the CheShift-2 server operates well under circumstances in which backbone chemical shifts are available but where local plasticity may render X-ray structural data ambiguous.

Through careful analysis of the vernacular, the paper focuses on the motivations and the communicative effectiveness of the use of dialect and questions the degree of realism or linguistic mimesis that Diritti was able to reach.

  17. The Pseudomonas aeruginosa chemotaxis methyltransferase CheR1 impacts on bacterial surface sampling.

    Directory of Open Access Journals (Sweden)

    Juliane Schmidt

    Full Text Available The characterization of factors contributing to the formation and development of surface-associated bacterial communities known as biofilms has become an area of intense interest since biofilms have a major impact on human health, the environment and industry. Various studies have demonstrated that motility, including swimming, swarming and twitching, seems to play an important role in the surface colonization and establishment of structured biofilms. Thereby, the impact of chemotaxis on biofilm formation has been less intensively studied. Pseudomonas aeruginosa has a very complex chemosensory system with two Che systems implicated in flagella-mediated motility. In this study, we demonstrate that the chemotaxis protein CheR1 is a methyltransferase that binds S-adenosylmethionine and transfers a methyl group from this methyl donor to the chemoreceptor PctA, an activity which can be stimulated by the attractant serine but not by glutamine. We furthermore demonstrate that CheR1 does not only play a role in flagella-mediated chemotaxis but that its activity is essential for the formation and maintenance of bacterial biofilm structures. We propose a model in which motility and chemotaxis impact on initial attachment processes, dispersion and reattachment and increase the efficiency and frequency of surface sampling in P. aeruginosa.

    2013-01-01

    At nesting colonies of American White Pelicans (Pelecanus erythrorhynchos), many chicks die from siblicide, severe weather, and disease; this results in carcasses available for scavenging by conspecifics (i.e., indirect cannibalism). Indirect cannibalism has not been reported previously for this species. We describe five cases of crèche-aged American White Pelican chicks consuming or attempting to consume dead younger chicks at two nesting colonies in the northern plains of North America. Cannibalism in the American White Pelican appears to be rare and likely plays no role in the species’ population ecology or dynamics; however, it might be an important survival strategy of individual chicks when food resources are limited.

    Laboratory work is the cornerstone of experimental planetary geochemistry, mineralogy, and petrology, but much is to be gained by "experiments" while on a planet surface. Earth-bound experiments are often limited in ability to control multiple conditions relevant to planetary bodies (e.g. cycles in temperature and vapor pressure of water), but observations on-planet provide a unique opportunity where conditions are native to the planet and those affected by sampling and analysis can be constrained. The CheMin XRD instrument on Mars Science Laboratory has been able to test mineral hydration in samples held for up to 300 Mars days (sols). Clay minerals sampled at Yellowknife Bay early in the mission had both collapsed (10 Å) and expanded (13.2 Å) basal spacing. Collapsed interlayers were expected, but larger spacing was not; it was uncertain whether larger basal spacing would collapse on prolonged exposure to warmer conditions inside CheMin. Observation over several hundred sols showed no collapse, with the conclusion that expanded interlayer spacing was due to partial intercalation by metal-hydroxyl groups that resist dehydration. More recently, a sample of the Murray Formation, Oudam, provided the first XRD detection of gypsum and a chance to observe gypsum stability. Laboratory work suggests gypsum should be stable at Mars surface conditions, and indeed gypsum has been observed from orbit at higher latitudes and in thick veins at Yellowknife Bay by Mastcam reflectance spectra. Laboratory experiments have shown that on dehydration the gypsum would not become X-ray amorphous but would rather transform to a water-deficient bassanite structure. Over a period of 37 sols, it was observed that the Oudam sample in CheMin transformed from an assemblage of gypsum+anhydrite, to gypsum+bassanite+anhydrite, and finally to bassanite+anhydrite. Mg-sulfates were also anticipated but have not been observed in CheMin despite chemical evidence for their presence. Unlike gypsum

  4. Stealing or Steeling the Image? The Failed Branding of the Guerrillero Heroico image of Che Guevara

    Directory of Open Access Journals (Sweden)

    Maria-Carolina Cambre

    2012-05-01

    Full Text Available This article traces the ongoing tension between those who would characterize Alberto Korda’s famous image of Che Guevara, The Guerrillero Heroico, as a brand, trademark or logo, and those who insist it is a political/cultural icon and non-commercial and that these categories are mutually exclusive. The question of whether the image has been emptied of political content, and the debate around the copyrighting of an image considered by many to be in the public domain and a cultural icon are explored. The long-lasting struggle over the meanings and collective memories associated with this image indicate the possibility that both processes of commodification and radicalization of the image of Che Guevara can coexist. Using the literature on consumer research to engage definitions of branding as a commercially geared venture, this article teases out the problematics of different uses of the photograph and its derivatives, and highlights ambiguities around the notions of creation and authorship. After examining this image’s role within Cuba, Cuban use outside of Cuba, and its commercial and non-commercial uses by non-Cubans, I conclude that attempts at branding products with this particular image fail, and therefore its copyrighting is irrelevant.

    The Crew Health Care System (CHeCS) is a group within the Space Life Science Directorate (SLSD) that focuses on the overall health of astronauts by reinforcing the three divisions - the Environmental Maintenance System (EMS), the Countermeasures System (CMS), and the Health Maintenance System (HMS). This internship provided opportunity to gain knowledge, experience, and skills in CHeCS engineering and operations tasks. Various and differing tasks allowed for occasions to work independently, network to get things done, and show leadership abilities. Specific exercises included reviewing hardware certification, operations, and documentation within the ongoing Med Kit Redesign (MKR) project, and learning, writing, and working various common pieces of paperwork used in the engineering and design process. Another project focused on the distribution of various pieces of hardware to off-site research facilities with an interest in space flight health care. The main focus of this internship, though, was on a broad and encompassing understanding of the engineering process as time was spent looking at each individual step in a variety of settings and tasks.

    Setting up at CERN a collective structure to mind children younger than two years, a so-called “crèche”, has been discussed at least since the early 1990s. Then, in February 2001, the Equal Opportunities Advisory Panel produced a memo to the Director of Administration in which it “invites the CERN Management to re-consider the possibility of creating a crèche at CERN”. As a result an ad hoc task force (“Bethléem”) was set up, which based its work on an informal questionnaire sent to CERN families with small children. Its study came up with some relevant parameters for “should CERN Management intend to undertake a minimal effort toward solving the crèche problem for its staff members”. Nothing was undertaken at that time. In the framework of the 2005 five yearly review “Working Group 6: Crèche” made another study of public and private  cr&a...

    Full Text Available Abstract Analyzing chemical datasets is a challenging task for scientific researchers in the field of chemoinformatics. It is important, yet difficult to understand the relationship between the structure of chemical compounds, their physico-chemical properties, and biological or toxic effects. To that respect, visualization tools can help to better comprehend the underlying correlations. Our recently developed 3D molecular viewer CheS-Mapper (Chemical Space Mapper divides large datasets into clusters of similar compounds and consequently arranges them in 3D space, such that their spatial proximity reflects their similarity. The user can indirectly determine similarity, by selecting which features to employ in the process. The tool can use and calculate different kind of features, like structural fragments as well as quantitative chemical descriptors. These features can be highlighted within CheS-Mapper, which aids the chemist to better understand patterns and regularities and relate the observations to established scientific knowledge. As a final function, the tool can also be used to select and export specific subsets of a given dataset for further analysis.

  8. Che-1/AATF: a critical co-factor for both wild type- and mutant-p53 proteins

    Full Text Available The p53 protein is a key player in a wide range of protein networks that allow the state of good health of the cell. Not surprisingly, mutations of the p53 gene are one of the most common alterations associated to cancer cells. Mutated forms of p53 (mtp53 not only lose the ability to protect the integrity of the genetic heritage of the cell, but acquire pro-oncogenic functions, behaving like dangerous accelerators of transformation and tumor progression. In recent years, many studies focused on investigating possible strategies aiming to counteract this mutant p53 gain of function but the results have not always been satisfactory. Che-1/AATF is a nuclear protein that binds to RNA polymerase II and plays a role in multiple fundamental processes, including control of transcription, cell cycle regulation, DNA damage response and apoptosis. Several studies showed Che-1/AATF as an important endogenous regulator of p53 expression and activity in a variety of biological processes. Notably, this same regulation was more recently observed also on mtp53. The depletion of Che-1/AATF strongly reduces the expression of mutant p53 in several tumors in vitro and in vivo, making the cells an easier target for chemotherapy treatments. In this mini review, we report an overview of Che-1/AATF functions and discuss a possible role of Che-1/AATF in cancer therapy, with particular regard to its action on p53/mtp53.

    Cholinesterase (ChE) activity was used as a biomarker for assessing exposure of common carp (Cyprinus carpio) to organophosphate and carbamate insecticides from irrigated agricultural waters. Carp were collected from a lake (Royal Lake) that receives most of its water from irrigation return flows and from a reference lake (Billy Clapp Lake) outside of the irrigation system. Results indicated that the mean whole-brain ChE activity of carp from Royal Lake (3.47 μmol/min/g tissue) was 34.2% less than that of carp from Billy Clapp Lake (5.27 μmol/min/g tissue) (p = 0.003). The depressed ChE activity in brain tissue of Royal Lake carp was in response to ChE-inhibiting insecticides detected in water samples in the weeks prior to tissue sampling; the most frequently detected insecticides included chlorpyrifos, azinphos-methyl, carbaryl, and ethoprop. Neither sex nor size appears to be a covariable in the analysis; ChE activity was not correlated with fish length or weight in either lake and there was no significant difference in ChE activity between the two sexes within each lake. Although organophosphate and carbamate insecticides can break down rapidly in the environment, this study suggests that in agricultural regions where insecticides are applied for extended periods of the year, nontarget aquatic biota may be exposed to high levels of ChE-inhibiting insecticides for a period of several months.

    The CheMin instrument on the Mars Science Laboratory (MSL) rover Curiosity uses a Co tube source and a CCD detector to acquire mineralogy from diffracted primary X-rays and chemical information from fluoresced X-rays. CheMin has been operating at the MSL Gale Crater field site since August 5, 2012 and has provided the first X-ray diffraction (XRD) analyses in situ on a body beyond Earth. Data from the first sample collected, the Rocknest eolian soil, identify a basaltic mineral suite, predominantly plagioclase (approx.An50), forsteritic olivine (approx.Fo58), augite and pigeonite, consistent with expectation that detrital grains on Mars would reflect widespread basaltic sources. Minor phases (each <2 wt% of the crystalline component) include sanidine, magnetite, quartz, anhydrite, hematite and ilmenite. Significantly, about a third of the sample is amorphous or poorly ordered in XRD. This amorphous component is attested to by a broad rise in background centered at approx.27deg 2(theta) (Co K(alpha)) and may include volcanic glass, impact glass, and poorly crystalline phases including iron oxyhydroxides; a rise at lower 2(theta) may indicate allophane or hisingerite. Constraints from phase chemistry of the crystalline components, compared with a Rocknest bulk composition from the APXS instrument on Curiosity, indicate that in sum the amorphous or poorly crystalline components are relatively Si, Al, Mg-poor and enriched in Ti, Cr, Fe, K, P, S, and Cl. All of the identified crystalline phases are volatile-free; H2O, SO2 and CO2 volatile releases from a split of this sample analyzed by the SAM instrument on Curiosity are associated with the amorphous or poorly ordered materials. The Rocknest eolian soil may be a mixture of local detritus, mostly crystalline, with a regional or global set of dominantly amorphous or poorly ordered components. The Rocknest sample was targeted by MSL for "first time analysis" to demonstrate that a loose deposit could be scooped, sieved to

    In addition to its role in DNA damage repair and recombination, the RecA protein, through its interaction with CheW, is involved in swarming motility, a form of flagella-dependent movement across surfaces. In order to better understand how SOS response modulates swarming, in this work the location of RecA and CheW proteins within the swarming cells has been studied by using super-resolution microscopy. Further, and after in silico docking studies, the specific RecA and CheW regions associated with the RecA-CheW interaction have also been confirmed by site-directed mutagenesis and immunoprecipitation techniques. Our results point out that the CheW distribution changes, from the cell poles to foci distributed in a helical pattern along the cell axis when SOS response is activated or RecA protein is overexpressed. In this situation, the CheW presents the same subcellular location as that of RecA, pointing out that the previously described RecA storage structures may be modulators of swarming motility. Data reported herein not only confirmed that the RecA-CheW pair is essential for swarming motility but it is directly involved in the CheW distribution change associated to SOS response activation. A model explaining not only the mechanism by which DNA damage modulates swarming but also how both the lack and the excess of RecA protein impair this motility is proposed. PMID:27766091

  20. Structural studies of conformational changes of proteins upon phosphorylation: Structures of activated CheY, CheY-N16-FliM complex, and AAA {sup +} ATPase domain of NtrC1 in both inactive and active states

    Protein phosphorylation is a general mechanism for signal transduction as well as regulation of cellular function. Unlike phosphorylation in eukaryotic systems that uses Ser/Thr for the sites of modification, two-component signal transduction systems, which are prevalent in bacteria, archea, and lower eukaryotes, use an aspartate as the site of phosphorylation. Two-component systems comprise a histidine kinase and a receiver domain. The conformational change of the receiver domain upon phosphorylation leads to signal transfer to the downstream target, a process that had not been understood well at the molecular level. The transient nature of the phospho-Asp bond had made structural studies difficult. The discovery of an excellent analogue for acylphosphate, BeF{sub 3}{sup -}, enabled structural study of activated receiver domains. The structure of activated Chemotaxis protein Y (CheY) was determined both by NMR spectroscopy and X-ray crystallography. These structures revealed the molecular basis of the conformational change that is coupled to phosphorylation. Phosphorylation of the conserved Asp residue in the active site allows hydrogen bonding of the T87 O{gamma} to phospho-aspartate, which in turn leads to the rotation of Y106 into the ''in'' position (termed Y-T coupling). The structure of activated CheY complexed with the 16 N-terminal residues of FliM (N16-FliM), its target, was also determined by X-ray crystallography and confirmed the proposed mechanism of activation (Y-T coupling). First, N16-FliM binds to the region on CheY that undergoes a significant conformational change. Second, the ''in'' position of Y106 presents a better binding surface for FliM because the sidechain of Y106 in the inactive form of CheY (''out'' position) sterically interferes with binding of N16-FliM. In addition to confirmation of Y-T coupling, the structure of the activated CheY-N16-FliM complex suggested that the N16

    Excavations carried out during the 1990s at Moula-Guercy cave Ardèche, France, yielded 108 hominid specimens dating to 100-120 Ka. In this paper, we describe and compare the 39 axial and appendicular specimens not including hand and foot bones. Among these remains are a large adult femur, several clavicles, a likely antimeric pair of radial heads, and a nearly complete superior pubic ramus. Analyses of this material indicate a clear affinity with Neanderthals by the presence of large and robust muscle attachments, thick long bone cortices, a long pubic ramus, and a superoinferiorly flattened clavicle shaft. The recovered remains reveal the presence of a mature male, a smaller mature individual, possibly a reproductive age female, an immature individual of age 10-12, and a second immature individual of age 4. Future analyses on the Moula-Guercy remains will illuminate ties to other known Neanderthal populations and contribute to the ongoing debate over the relative rate of Neanderthal metric growth.

    The hand and foot remains from Moula-Guercy cave (Ardèche, France) comprise 24 specimens of Eemian age (ca. 120 ka). The specimens include primarily complete elements, which are rare among the Moula-Guercy postcrania. The hand remains have several characteristic Neanderthal traits including a laterally facing (parasagittally oriented) second metacarpal-capitate articulation, a short styloid process, a wide proximal articular surface on the third metacarpal, and absolutely expanded apical tuberosities on the distal hand phalanges relative to modern humans. The foot remains include several incomplete elements along with an antimeric pair of naviculars, a medial cuneiform and cuboid, and a single complete element from each of the distal segments (one each: metatarsal, proximal foot phalanx, intermediate foot phalanx, distal foot phalanx). Consistent among the specimens are relatively wide diaphyses for length in the metatarsals and phalanges and large and prominent muscle attachments, both consistent with previously published Neanderthal morphology. The hand and foot collection from Moula-Guercy is an important dataset for future studies of Neanderthal functional morphology, dexterity, and behavior as it represents a previously undersampled time period for European Neanderthals.

    Full Text Available The compromise acquired since 1991 by successive Chilean governments to recognise indigenous presence in the organization of the State at a constitutional level has revealed the mutual academic and legal ignorance in relation to the evidence for Mapu-Che recognition. This work revisits the historical and legal relationship between the Chilean and the Mapu State, which until the Chilean conquest of the Mapu in the 1880s was carried out through Treaties and Parliaments that implied a mutual recognition of both identities in an international sphere. Study commissions official reports and pleas for truth for a new treaty, first by the United Nations, and later by the Republic of Chile noted the evidence of the constitutional and international significance of the Treaties, but Chile has since transformed its peculiar form of constitutional recognition of the indigenous presence into a display of national unity. This cover-up stems both from the desire to maintain an exclusive Constitution, and the certainty that any other form of recognition would lead to a reconsideration of the roots of the constitutional foundations of the Republic of Chile.

The meanvalue of ABR threshold and the activities of LDH and ChE in the Wistar 12-month old group at rel-evant sections were significantly greater than those in the two 3-month old groups (P<0.05),whereas the mean value of ABR threshold and the activities of LDH and ChE in the SHRSP 12-month old group at relevant sections were significantly higher than those in the 3-month old controlgroup (P<0. 01). It was concluded that presbycusis existed in the Wistar 12-month old group rats.The glycogenosis and the abnormal secretion of neural transmitter were discerned after hyperten-sion. All the above factors may worsen the aging of the hearing system.

    The Azospirillum brasilense chemotaxis-like Che1 signal transduction pathway was recently shown to modulate changes in adhesive cell surface properties that, in turn, affect cell-to-cell aggregation and flocculation behaviors rather than flagellar-mediated chemotaxis. Attachment to surfaces and root colonization may be functions related to flocculation. Here, the conditions under which A. brasilense wild-type Sp7 and che1 mutant strains attach to abiotic and biotic surfaces were examined using in vitro attachment and biofilm assays combined with atomic force microscopy and confocal microscopy. The nitrogen source available for growth is found to be a major modulator of surface attachment by A. brasilense and could be promoted in vitro by lectins, suggesting that it depends on interaction with surface-exposed residues within the extracellular matrix of cells. However, Che1-dependent signaling is shown to contribute indirectly to surface attachment, indicating that distinct mechanisms are likely underlying flocculation and attachment to surfaces in A. brasilense.

  14. The CheMin Mineralogy Instrument on Mars Science Laboratory: Analysis of Clays and Sulfates at Gale Crater

    2011-12-01

    A principal goal of the Mars Science Laboratory (MSL) Curiosity rover is to identify and characterize present or past habitable environments on Mars. Mineralogy is important in this regard because minerals are thermodynamic phases, stable under specific (and known) conditions of temperature, pressure and composition. By determining the mineralogical composition of a rock or soil, one can often deduce the conditions under which it formed or its subsequent diagenetic or metamorphic history. The CheMin instrument on MSL will return accurate mineral determinations and quantitative mineralogical information from scooped soil samples and drilled rock powders collected at Gale crater during Curiosity's 1-Mars-year nominal mission. Individual analyses will require several hours over one or more Mars sols. For typical well-ordered minerals, CheMin will have a Minimum Detection Limit (MDL) of 4X MDL (12%). The resolution of the diffraction patterns is 0.3° 2θ. This performance is sufficient to allow for the detection and quantification of virtually all minerals. Orbital imagery and analysis of reflectance spectra from Gale Crater reveal a wealth of mineralogical and morphological features suggestive of ancient habitable environments and water. CheMin is quite capable of discriminating and quantifying the clay and sulfate mineralogies expected within the landing ellipse and in the strata of the central mound, the primary target at Gale. Both polyhydrated and monohydrated (kieserite) sulfate minerals are distributed in mappable strata at Gale. Virtually all hydrated and nonhydrated sulfates are uniquely identifiable and quantifiable with CheMin. Breadboard and commercial equivalents of the CheMin instrument have already been used extensively in evaporite field localities ranging from Death Valley to Antarctica and Spitsbergen; at all these sites the identification and characterization of sulfate, carbonate, and halide mineralogy has been comparable to that of laboratory

    The Mediterranean basin is considered to be one of the "hotspots" for climate change. One of the main factors in these changes is the availability and distribution of water, both in time and space. To gain more understanding about the hydrological cycle in the Mediterranean basin and to quantify the related processes, the HYdrological cycle in the Mediterranean EXperiment (HyMeX) was set up. This experiment focuses on inter-annual to decadal variability in the coupled Mediterranean system, running during the second decade of the 21st century. During this long experiment, special intensive observation periods are planned, of which the first passed during the autumn of 2012. Within the HyMeX framework, one working group pays special attention to (flash) floods and heavy rainfall. To investigate this, several (small) catchments were heavily instrumented during the first special observation period. We show the first results on rainfall estimation employing an optical link, a microwave link, and a disdrometer in the Ardèche catchment in the south of France for the first special observation period of HyMeX. Optical and microwave links can be employed to estimate path-averaged rain intensities along a transect of several kilometers, similar in length to the cross-section of a small catchment. The transmitted signal is attenuated by rain along the link path causing a decrease in received power at the end of the link. The attenuation of this signal has a power-law relation to the average rainfall intensity along the link. As a reference, the disdrometer is placed at one end of the link. Link-based rainfall intensities are compared to those based on disdrometer data. However, due to the nature of the observational technique (point measurement vs. average along a link) errors in representation may occur. The estimation of rainfall intensity from attenuation can be hampered by a number of factors. Principal among these are: moisture on the antennae that is perceived to be

    Full Text Available Secondo Georges Canguilhem non c’è verità se non quella prodotta e non scoperta dalla scienza. È il valore stesso della filosofia ad essere “altrove che nella verità”. Questo valore non veritativo risiede forse, per il pensatore francese, in qualcosa che egli definisce come un senso o un concetto iscritto materialmente nella vita. È il vivente stesso, quel vivente di cui la scienza in quanto ricerca della verità è a sua volta una semplice espressione, a contenere il concetto, o meglio, ad essere il movimento stesso della concettualizzazione. “Elsewherethan in the truth?” Philosophy, science and life in Georges Canguilhem'sthought.

    We report the positive identification of several members of the guerrillas led by Ernesto "Che" Guevara on the 1960 s in Bolivia by means of DNA fingerprinting. Successful DNA typing of both short tandem repeat loci and the hypervariable region of the human mitochondrial DNA was achieved after extracting total DNA from bones obtained from two burial sites. Given the size of the Cuban database for the STR allele frequencies, a conservative approach was followed to estimate the statistical significance of the genetic evidence. The estimated probabilities of paternity for the two cases in which the paternity logic was applied were higher than 99%. One case was analyzed using mitochondrial DNA and could not be excluded from the identity proposed by the forensic anthropology team. A fourth case was identified by exclusion, on the basis of the positive identification of the other remains, the historical and other anthropological evidence.

    Our aim is to upregulate the expression level of the dystrophin related gene utrophin in Duchenne muscular dystrophy, thus complementing the lack of dystrophin functions. To this end, we have engineered synthetic zinc finger based transcription factors. We have previously shown that the artificial three-zinc finger protein named Jazz fused with the Vp16 activation domain, is able to bind utrophin promoter A and to increase the endogenous level of utrophin in transgenic mice. Here, we report on an innovative artificial protein, named CJ7, that consists of Jazz DNA binding domain fused to a novel activation domain derived from the regulatory multivalent adaptor protein Che-1/AATF. This transcriptional activation domain is 100 amino acids in size and it is very powerful as compared to the Vp16 activation domain. We show that CJ7 protein efficiently promotes transcription and accumulation of the acetylated form of histone H3 on the genomic utrophin promoter locus.

    The Simplified Simple Biosphere model (SSiB) is validated in off-line simulations against field measurements in the summer of 2001 from the China Heavy Rainfall Experiment and Study (CHeRES) over a grassland site located in the lower reaches of the Yangtze River. When initialized and driven by the observed atmospheric forcing, the model reproduced the observed surface heat fluxes and surface skin temperature realistically. The model was also able to well simulate the variation of soil water content. The sensitivity experiments found that the leaf reflectance was the most significant parameter in improving the estimation of surface albedo during both wet and dry periods. This study suggests that the model is capable of simulating the physical processes and of assessing the impact of biophysical parameters that relate to land-atmosphere interactions over the eastern Asian monsoon regions, which is crucial for mesoscale atmospheric models.

    Full Text Available Introduction and Objectives: The appearance of nosocomial bacterial resistance represents a problem of growing concern because it largely affects the evolution of patients and the health resources devoted to it. The objective of this work was to determine the most common germs and their microbial resistance. Methods: A descriptive retrospective study was carried out analyzing the result of the isolation of germs from all type of secretions and from the blood cultures of a group ofpatients hospitalized at the Ernesto Che Guevara Cardiology Hospital in a five year period. Results: A total of 397 strains were isolated, 77 Staphylococcus aureus and 320 Enterobacteriaceae. The former presented 100% resistance to penicillin. The Staphylococcus sensitive to methicillin presented 4.9 % resistance to cotrimoxazole and gentamicin. The strains resistant to methicillin or oxacillin had a high resistance to gentamicin (87.5 % and ciprofloxacin (81.2 %, a medium resistance to cefazolin and oxacilline (20.5 %, and just 12.5 percent resistance to cotrimoxazole. Conclusions: the Staphylococcus aureus and the Enterobacteriaceae were the most common germs. The preoperative prophylaxis in these patients must not be done with cefazolin as a routine because the staphylococci resistant to methicillin or oxacillin have influence on other antimicrobials.

    Full Text Available In jüngster Zeit wird in qualitativen Forschungsprojekten verstärkt neben verschiedenen Interviewformen und Dokumentenanalysen die Methode der teilnehmenden Beobachtung eingesetzt, um Vermittlungsprozesse in der öffentlichen Arbeitsverwaltung zu untersuchen. Im Zentrum der Beobachtung steht die Ebene konkreter Interaktionen der institutionellen Bearbeitung von Arbeitslosigkeit, also jene Interaktionen, die in Beratungsgesprächen stattfinden, in denen Vermittlerinnen oder Vermittler und Arbeitsuchende interagieren. Im vorliegenden Beitrag soll an einem qualitativen Forschungsprojekt zu einem Modellversuch der Bundesagentur für Arbeit ausgeführt und diskutiert werden, wie die teilnehmende Beobachtung eingesetzt wurde, um Beratungsgespräche mehrdimensional zu analysieren. Um die Komplexität des empirischen Gegenstandes des Vermittlungs- und Beratungsgesprächs adäquat beobachten zu können, wurde für die Interaktionsbeobachtungen ein Kategoriensystem entwickelt, das verbale und non-verbale Interaktionsbestandteile in ihrem Zusammenspiel der interpretierenden Analyse zugänglich machen soll. Mittels der Aufzeichnung von non-verbalen Äußerungen in institutionalisierten Interaktionskontexten kann beispielsweise ex post rekonstruiert werden, was passiert, wenn beide Gesprächspartner/innen schweigen. Gerade die Kombination der genutzten Interaktionskategorien führt immer dann zu einem Informationsgewinn, wenn die verbale Ebene sich auf die Sachebene konzentriert und andere Interaktionskontexte andere Deutungszusammenhänge offenlegen, sodass auf diese Weise ein komplexeres Bild der beobachteten Situation gewonnen werden kann.

    2013-05-01

    Full Text Available This essay aims to investigate Alberto Moravia’s novel L’uomo che guarda (1985 through a psychoanalytic understanding of desire, specifically employed as an interpretive device. By primarily speaking of desire from a Lacanian perspective, I will focus in particular on Massimo Recalcati’s further elaborations of Lacan's theory, with special regard to his notion of 'hyper-modernity'. At the same time, by attempting a structural analysis of the novel, I will interpret desire as a drive that shape and organize the plot, following Peter Brook’s seminal work Reading for the plot. My reading allows therefore to see desire as an interpretive device reassessing Moravia's novel in both thematic and structural terms. More specifically, the analysis of the main characters in the light of this perspective will enable a shift in interpretation from the level of the plot to a deeper inquiry into issues of social and generational conflict, thereby enabling a new reading of the novel in the light of the ideological, political and intellectual turmoil occurred in Italy between the Sixties and the Seventies.

    The dynamics of globular proteins can be described in terms of transitions between a folded native state and less-populated intermediates, or excited states, which can play critical roles in both protein folding and function. Excited states are by definition transient species, and therefore are difficult to characterize using current experimental techniques. Here, we report an atomistic model of the excited state ensemble of a stabilized mutant of an extensively studied flavodoxin fold protein CheY. We employed a hybrid simulation and experimental approach in which an aggregate 42 milliseconds of all-atom molecular dynamics were used as an informative prior for the structure of the excited state ensemble. This prior was then refined against small-angle X-ray scattering (SAXS) data employing an established method (EROS). The most striking feature of the resulting excited state ensemble was an unstructured N-terminus stabilized by non-native contacts in a conformation that is topologically simpler than the native state. Using these results, we then predict incisive single molecule FRET experiments as a means of model validation. This study demonstrates the paradigm of uniting simulation and experiment in a statistical model to study the structure of protein excited states and rationally design validating experiments.

    Following genotoxic stress, cells activate a complex signalling network to arrest the cell cycle and initiate DNA repair or apoptosis. The tumour suppressor p53 lies at the heart of this DNA damage response. However, it remains incompletely understood, which signalling molecules dictate the choice between these different cellular outcomes. Here, we identify the transcriptional regulator apoptosis-antagonizing transcription factor (AATF)/Che-1 as a critical regulator of the cellular outcome of the p53 response. Upon genotoxic stress, AATF is phosphorylated by the checkpoint kinase MK2. Phosphorylation results in the release of AATF from cytoplasmic MRLC3 and subsequent nuclear translocation where AATF binds to the PUMA, BAX and BAK promoter regions to repress p53-driven expression of these pro-apoptotic genes. In xenograft experiments, mice exhibit a dramatically enhanced response of AATF-depleted tumours following genotoxic chemotherapy with adriamycin. The exogenous expression of a phospho-mimicking AATF point mutant results in marked adriamycin resistance in vivo. Nuclear AATF enrichment appears to be selected for in p53-proficient endometrial cancers. Furthermore, focal copy number gains at the AATF locus in neuroblastoma, which is known to be almost exclusively p53-proficient, correlate with an adverse prognosis and reduced overall survival. These data identify the p38/MK2/AATF signalling module as a critical repressor of p53-driven apoptosis and commend this pathway as a target for DNA damage-sensitizing therapeutic regimens.

    Full Text Available The basic parameters of extra-tropical cyclones in the northern Baltic are examined in relation to extreme sea level events at Estonian coastal stations between 1948 and 2010. The hypothesis that extreme sea level events might be caused not by one intense extra-tropical cyclone, as suggested by earlier researchers, but by the temporal clustering of cyclones in a certain trajectory corridor, is tested. More detailed analysis of atmospheric conditions at the time of the two most extreme cases support this concept: the sequence of 5 cyclones building up the extreme sea level within about 10 days was very similar in structure and periodicity.

    Full Text Available Oggi la ricerca del posto “fisso” sembra essere il sogno irraggiungibile di molti giovani precari e la “flessibilità”, una parola d’ordine con cui si aspirava a riformare il mondo del lavoro e che tanto in voga sembrava essere negli anni ’90, è diventata sinonimo di incertezza, precarietà, se non addirittura sfruttamento. Ma c’era chi proprio nel lavoro che oggi definiremo precario, vedeva l’unica possibilità per restare libero dalle leggi di mercato e dai potenti poteri editoriali Newyorkesi. In questo articolo proviamo a gettare uno sguardo al mito letterario con cui, il rifiutare un posto fisso, significava rivendicare la propria libertà, un mito romantico certo, e sicuramente distante dalla realtà, ma che ha affascinato un’intera generazione di scrittori, poeti, musicisti. Da Jack London, passando attraverso la San Francisco Renaissance e la Beat Generation, fino ad arrivare al fenomeno della così detta generazione Hippy, il sogno americano sembrava essere quello di una frontiera mobile in cui, la strada, sembrava non avere mai fine.

    Full Text Available Abstract Background Photo- and chemotaxis of the archaeon Halobacterium salinarum is based on the control of flagellar motor switching through stimulus-specific methyl-accepting transducer proteins that relay the sensory input signal to a two-component system. Certain members of the transducer family function as receptor proteins by directly sensing specific chemical or physical stimuli. Others interact with specific receptor proteins like the phototaxis photoreceptors sensory rhodopsin I and II, or require specific binding proteins as for example some chemotaxis transducers. Receptor activation by light or a change in receptor occupancy by chemical stimuli results in reversible methylation of glutamate residues of the transducer proteins. Both, methylation and demethylation reactions are involved in sensory adaptation and are modulated by the response regulator CheY. Results By mathematical modeling we infer the kinetic mechanisms of stimulus-induced transducer methylation and adaptation. The model (deterministic and in the form of ordinary differential equations correctly predicts experimentally observed transducer demethylation (as detected by released methanol in response to attractant and repellent stimuli of wildtype cells, a cheY deletion mutant, and a mutant in which the stimulated transducer species is methylation-deficient. Conclusions We provide a kinetic model for signal processing in photo- and chemotaxis in the archaeon H. salinarum suggesting an essential role of receptor cooperativity, antagonistic reversible methylation, and a CheY-dependent feedback on transducer demethylation.

    The CheMin instrument on the Mars Science Laboratory (MSL) rover Curiosity is an X-ray diffraction (XRD) and X-ray fluorescence (XRF) instrument capable of providing the mineralogical and chemical compositions of rocks and soils on the surface of Mars. CheMin uses a microfocus X-ray tube with a Co target, transmission geometry, and an energy-discriminating X-ray sensitive CCD to produce simultaneous 2-D XRD patterns and energy-dispersive X-ray histograms from powdered samples. Piezoelectric vibration of the cell is used to randomize the sample to reduce preferred orientation effects. Instrument details are provided in [1, 2, 3]. Analyses of rock and soil samples by the Mars Exploration Rovers (MER) show nanophase ferric oxide (npOx) is a significant component of the Martian global soil [4] and is thought to be one of the major contributing phases that the Curiosity rover will encounter if a soil sample is analyzed in Gale Crater. Because of the nature of this material, npOx will likely contribute to an X-ray amorphous or short-order component of a XRD pattern measured by the CheMin instrument.

    Full Text Available Nel presente contributo vengono offerte alcune riflessioni sulla traduzione di aspetti culturalmente specifici nel testo letterario, e in particolare sulle versioni italiana e slovena del romanzo Les Fleurs bleues di Raymond Queneau, che sono opera rispettivamente di Italo Calvino e di Ana Barič Moder. Al centro dellʼattenzione è soprattutto la dicotomia traduttiva tra lʼapproccio straniante e quello domesticante. Un esame del testo originale e delle due traduzioni ha dimostrato che ambedue i traduttori si sono sforzati di preservare i caratteri della cultura di partenza iscritti nel romanzo queneauiano. Allo stesso tempo, però, hanno cercato di integrare le proprie versioni negli ambienti dʼarrivo quando ciò pareva necessario per rendere possibile il pieno funzionamento delle due traduzioni come opere letterarie che, nei specifici contesti italiano e sloveno, sono destinate ad avere la funzione di entità letterarie a sé stanti, cioè indipendenti dal loro primario legame con il testo di partenza francese. Fatte queste premesse, lʼapproccio generale dei due traduttori può essere caratterizzato come relativamente addomesticante, anche se in entrambe le versioni, e in particolare in quella italiana, viene concesso ampio spazio anche allo straniamento, purché esso non incrini la funzionalità della traduzione.

    Full Text Available Drop foot is a common problem following neurological conditions such as stroke, multiple sclerosis, brain injury and incomplete spinal cord injury, consisting in the inability to lift the foot in the swing phase of the gait cycle. Since dropped foot is frequently associated with spasticity and more complex movement problems affecting the whole person, it can result in tripping and falling.br Functional electrical Stimulation (FES devices are designed to address this problem. The peroneal nerve is stimulated using surface electrodes at its most superficial position in its course, where it passes over the head of the fibula bone. The peroneal nerve stimulation induces activity in the tibialis anterior and peroneous longus muscles, causing dorsiflexion and eversion of the foot. The stimulation is synchronised to the gait using a pressure sensitive heel switch. When weight is taken from the switch, stimulation is given. FES results in an economisation of gait and an improvement of walking speed and walking distance.br Recently, an implantable 4-channel drop foot stimulator with independent electrode adjustment resulting in a more specific stimulation showed an improvement of walking speed and a restoration of gait in patients with stroke. The therapeutic effect might be improved compared with surface stimulation. p bKurzfassung:/b Die Schwäche der Vorfußhebung ist ein weit verbreitetes Problem bei neurologischen Erkrankungen wie Schlaganfall, Multiple Sklerose, Schädelhirntrauma und inkomplettem Querschnittsyndrom und führt zu einer insuffizienten Hebung des Vorfußes in der Schwungphase des Gangzyklus. Vielfach ist die Schwäche der Vorfußhebung assoziert mit Spastizität und komplexeren motorischen Problemen, dies führt zu gehäuftem Stolpern und Stürzen.br Die funktionelle elektrische Stimulation (FES ist eine Therapiemodalität zur Korrektur dieses motorischen Problems.

    Protein phosphorylation is a general mechanism for signal transduction as well as regulation of cellular function. Unlike phosphorylation in eukaryotic systems that uses Ser/Thr for the sites of modification, two-component signal transduction systems, which are prevalent in bacteria, archea, and lower eukaryotes, use an aspartate as the site of phosphorylation. Two-component systems comprise a histidine kinase and a receiver domain. The conformational change of the receiver domain upon phosphorylation leads to signal transfer to the downstream target, a process that had not been understood well at the molecular level. The transient nature of the phospho-Asp bond had made structural studies difficult. The discovery of an excellent analogue for acylphosphate, BeF3-, enabled structural study of activated receiver domains. The structure of activated Chemotaxis protein Y (CheY) was determined both by NMR spectroscopy and X-ray crystallography. These structures revealed the molecular basis of the conformational change that is coupled to phosphorylation. Phosphorylation of the conserved Asp residue in the active site allows hydrogen bonding of the T87 Oγ to phospho-aspartate, which in turn leads to the rotation of Y106 into the ''in'' position (termed Y-T coupling). The structure of activated CheY complexed with the 16 N-terminal residues of FliM (N16-FliM), its target, was also determined by X-ray crystallography and confirmed the proposed mechanism of activation (Y-T coupling). First, N16-FliM binds to the region on CheY that undergoes a significant conformational change. Second, the ''in'' position of Y106 presents a better binding surface for FliM because the sidechain of Y106 in the inactive form of CheY (''out'' position) sterically interferes with binding of N16-FliM. In addition to confirmation of Y-T coupling, the structure of the activated CheY-N16-FliM complex suggested that the

    Site-directed scarless mutagenesis is an essential tool of modern pathogenesis research. We describe an optimized two-step protocol for genome editing in Salmonella enterica serovar Typhimurium to enable multiple sequential mutagenesis steps in a single strain. The system is based on the λ Red recombinase-catalyzed integration of a selectable antibiotics resistance marker followed by replacement of this cassette. Markerless mutants are selected by expressing the meganuclease I-SceI which induces double-strand breaks in bacteria still harboring the resistance locus. Our new dual-functional plasmid pWRG730 allows for heat-inducible expression of the λ Red recombinase and tet-inducible production of I-SceI. Methyl-accepting chemotaxis proteins (MCP) are transmembrane chemoreceptors for a vast set of environmental signals including amino acids, sugars, ions and oxygen. Based on the sensory input of MCPs, chemotaxis is a key component for Salmonella virulence. To determine the contribution of individual MCPs we sequentially deleted seven MCP genes. The individual mutations were validated by PCR and genetic integrity of the final seven MCP mutant WRG279 was confirmed by whole genome sequencing. The successive MCP mutants were functionally tested in a HeLa cell infection model which revealed increased invasion rates for non-chemotactic mutants and strains lacking the MCP CheM (Tar). The phenotype of WRG279 was reversed with plasmid-based expression of CheM. The complemented WRG279 mutant showed also partially restored chemotaxis in swarming assays on semi-solid agar. Our optimized scarless deletion protocol enables efficient and precise manipulation of the Salmonella genome. As demonstrated with whole genome sequencing, multiple subsequent mutagenesis steps can be realized without the introduction of unwanted mutations. The sequential deletion of seven MCP genes revealed a significant role of CheM for the interaction of S. Typhimurium with host cells which might give

    Among the paintings and engravings found in the Chauvet-Pont d'Arc cave (Ardèche, France), several peculiar spray-shape signs have been previously described in the Megaloceros Gallery. Here we document the occurrence of strombolian volcanic activity located 35 km northwest of the cave, and visible from the hills above the cave entrance. The volcanic eruptions were dated, using 40Ar/39Ar, between 29 ± 10 ka and 35 ± 8 ka (2σ), which overlaps with the 14C AMS and thermoluminescence ages of the first Aurignacian occupations of the cave in the Megaloceros Gallery. Our work provides the first evidence of an intense volcanic activity between 40 and 30 ka in the Bas-Vivarais region, and it is very likely that Humans living in the Ardèche river area witnessed one or several eruptions. We propose that the spray-shape signs found in the Chauvet-Pont d'Arc cave could be the oldest known depiction of a volcanic eruption, predating by more than 34 ka the description by Pliny the Younger of the Vesuvius eruption (AD 79) and by 28 ka the Çatalhöyük mural discovered in central Turkey.

    Full Text Available Lo scenario dell’istruzione in Italia si è caratterizzato negli anni come un sistema formativo inceppato, inadeguato, con un bilancio tutt’ora in passivo, ancora molto lontano dal poter realizzare gli importanti obiettivi di Lisbona. L’orizzonte da costruire è quello di una scuola di qualità per tutti, capace di rappresentare un’esperienza positiva, proattiva di sviluppo personale e sociale, e non un bruciante fallimento per i ragazzi, futuri adulti e cittadini del mondo. Nell’ottica di promuovere una riforma del sistema formativo ed, al contempo, contrastare la “piaga” della dispersione scolastica, la Legge finanziaria 2007 ed il successivo Regolamento sull’obbligo di istruzione introducono importanti novità, che si attueranno in un primo biennio sperimentale, a partire dall’anno scolastico 2007/08: l’innalzamento di due anni di obbligo di istruzione, o nel sistema sistema dell’istruzione secondaria superiore o nel sistema dell’istruzione e formazione professionale, anche con l’opzione dei percorsi triennali nella formazione professionale, per complessivi 10 anni, l’entrata nel mondo del lavoro è stata elevata a 16 anni. Il valore qualitativo, innovativo e sperimentale che le esperienze maturate sul campo, in prima applicazione biennale, riusciranno ad esprimere, aprirà per le Regioni e gli Enti Locali nuove opportunità di azione e costituirà la base di lancio propedeutica alla messa a regime della riforma prevista per l’anno scolastico 2009/10. In questo contesto, l’esperienza maturata dalla Regione Emilia-Romagna, in termini di innovazione, know how e prassi positiva, risulta particolarmente significativa per un sistema formativo regionale considerato, da più parti, all’avanguardia nel nostro Paese (es.: il livello della dispersione scolastica si attesta al 6% contro il 20-22% del quadro della media nazionale.

    Full Text Available This study explores how catchment heterogeneity and variability can be summarized in simplified models, representing the dominant hydrological processes. It focuses on Mediterranean catchments, characterized by heterogeneous geology, pedology, and land use, as well as steep topography and a rainfall regime in which summer droughts contrast with high-rainfall periods in autumn. The Ardèche catchment (south-east France, typical of this environment, is chosen to explore the following questions: (1 can such a Mediterranean catchment be adequately characterized by simple dynamical systems approach and what are the limits of the method under such conditions? (2 What information about dominant predictors of hydrological variability can be retrieved from this analysis in such catchments? In this work we apply the data-driven approach of Kirchner (WRR, 2009 to estimate discharge sensitivity functions that summarize the behavior of four sub-catchments of the Ardèche, using non-vegetation periods (November–March from 9 years of data (2000–2008 from operational networks. The relevance of the inferred sensitivity function is assessed through hydrograph simulations, and through estimating precipitation rates from discharge fluctuations. We find that the discharge-sensitivity function is downward-curving in double-logarithmic space, thus allowing further simulation of discharge and non-divergence of the model, only during non-vegetation periods. The analysis is complemented by a Monte-Carlo sensitivity analysis showing how the parameters summarizing the discharge sensitivity function impact the simulated hydrographs. The resulting discharge simulation results are good for granite catchments, found to be predominantly characterized by saturation excess runoff and sub-surface flow processes. The simple dynamical system hypothesis works especially well in wet conditions (peaks and recessions are well modeled. On the other hand, poor model performance is

    Full Text Available An upside down survey: shores and sea bed hi-res 3D digital models Laser scanning and interferometric bathymetry represent the cutting edge of coastal survey technology and can be very beneficial for mapping complicated waterside areas. The similarity of the data provided by the two systems (point cloud and intensity value make it easy to integrate the two surveys using PolyWorks commercial software. The final product is a single 3D model made up of bathymetry and topography. Since 2004 Codevintec tested the integration of these two methodologies, carrying out a number of high resolution surveys, generating a complete and accurate digital model of areas both above and below water level, a result inimitable by any other topographical survey method. The 3D-laser scanner was an Optech ILRIS-ER that allows scanning in dynamic from the boat while a SEA SWATHplus-H wide swathsonar system was used to collect underwater topography. A combined GPS and inertial platform (Applanix POS/MV 320 is used to measure position and 3D attitude of the two sensors during the survey.

    Full Text Available This paper presents the results obtained from an interdisciplinary study of the level D archaeological assemblages from Payre (Ardèche, France. This site is dated to the final of OIS 6 and the beginning of OIS 5. The combined analysis of the lithic and faunal assemblages accumulated and their management “into” and “out of” the site gives a better understanding of the behaviour of the Neanderthal groups that inhabited it. This study has allowed us to correlate the territorial exploitation for game hunting and for raw material procurement, within the context of seasonal short term occupations probably during the end of autumn and the beginning of winter.

    Faults may have a complex internal structure, including fault core and damage zone, and can act as major conduits for fluid migration. The migration of fluids along faults is generally associated with strong fluid-rock interaction, forming large amounts of cement that fill in the fractures. The cementation of the fault fractures is considered to be one of the important parameters of fault sealing. The different components of faults have diverse geochemical features because of varying physical characteristics. The investigation of the geochemical characteristics of the fault and damage zones could provide important information about the fault sealing process, which is very important in oil and gas exploration. To understand the fault-cemented sealing process, detailed geochemical studies were conducted on the fault and damage zones of the Hong-Che Fault of the northwestern Junggar Basin in China. The major and trace element data of our study suggest that the fault core is characterized by higher loss on ignition (LOI), potassium loss, Chemical Index of Alteration (CIA), and Plagioclase Index of Alteration (PIA) values and lower high field strength element (HFSE), large-ion lithosphile element (LILE), and rare earth element (REE) concentrations compared with the damage zone, implying more serious elemental loss and weathering of the fault core compared with the damage zone during faulting. The carbon and oxygen isotope data reveal that the cement of the Hong-Che Fault Zone formed due to multiple sources of fluids. The fault core was mainly affected by deep sources of hydrothermal fluids. In combination with previous studies, we suggest a potential fault-cemented sealing process during the period of fault movement. The fault core acts as the fluid conduit during faulting. After faulting, the fault core is cemented and the damage zone becomes the major conduit for fluid migration. The cementation firstly occurs on two sides of the damage zone in the upper part of the

    The Mars Science Laboratory mission was launched from Cape Canaveral, Florida on Nov. 26, 2011 and landed in Gale crater, Mars on Aug. 6, 2012. MSL's mission is to identify and characterize ancient "habitable" environments on Mars. MSL's precision landing system placed the Curiosity rover within 2 km of the center of its 20 X 6 km landing ellipse, next to Gale's central mound, a 5,000 meter high pile of laminated sediment which may contain 1 billion years of Mars history. Curiosity carries with it a full suite of analytical instruments, including the CheMin X-ray diffractometer, the first XRD flown in space. CheMin is essentially a transmission X-ray pinhole camera. A fine-focus Co source and collimator transmits a 50µm beam through a powdered sample held between X-ray transparent plastic windows. The sample holder is shaken by a piezoelectric actuator such that the powder flows like a liquid, each grain passing in random orientation through the beam over time. Forward-diffracted and fluoresced X-ray photons from the sample are detected by an X-ray sensitive Charge Coupled Device (CCD) operated in single photon counting mode. When operated in this way, both the x,y position and the energy of each photon are detected. The resulting energy-selected Co Kalpha Debye-Scherrer pattern is used to determine the identities and amounts of minerals present via Rietveld refinement, and a histogram of all X-ray events constitutes an X-ray fluorescence analysis of the sample.The key role that definitive mineralogy plays in understanding the Martian surface is a consequence of the fact that minerals are thermodynamic phases, having known and specific ranges of temperature, pressure and composition within which they are stable. More than simple compositional analysis, definitive mineralogical analysis can provide information about pressure/temperature conditions of formation, past climate, water activity and the like. Definitive mineralogical analyses are necessary to establish

Abbiamo avuto l’onore della sua amicizia fraterna e solidale, conosciuto l’azzardo e la radicalità delle sue scelte di vita, la sua dolce timidezza e l’ardita padronanza e consapevolezza del suo ruolo: anni di discussioni, di confronto, di legame cementato da infuocati innamoramenti intellettuali per uno scrittore, un poeta, un regista, di accese ironie sui nostri caratteri, di scontri politici e furibondi litigi finiti in un abbraccio. Anche per Bruno Brancher, milanese di tutti e di nessuno, il ricordo si fa memoria per le sue mille improvvise e imprevedibili incursioni in terra salentina. Non era un uomo facile, anche se aveva dalla sua parte il puntiglio dell’innocenza tipica del ladro gentiluomo. Portava leggero il fardello di due vite in una: la prima segnata da una marginalità, fattasi a volte precariamente lussuosa con i proventi di furti e disarmanti rapine; l’altra con la faccia del redento, che con la scoperta della scrittura diventa cosciente di sé.

    A trace element record (Mg, Sr, Ba, Al, Si, P, Y, Zn) covering the ca. 133 ka to ca. 124 ka time interval was acquired from a flowstone core from Tana che Urla Cave (central Italy). It was compared with stable isotope data to investigate the environmental evolution in response to regional and extra-regional climate changes in the period corresponding to the latter part of the Penultimate Deglaciation and the first part of the Last Interglacial (Eemian). Trace element geochemical changes on centennial and millennial time scales responded to changes in hydrological input, variations in the supply and transport of catchment erosion products to the cave, including those linked to intense rainfall events, and to the state of the overlying soil and vegetation. Abrupt increases in precipitation and the progressive development of soil and vegetation occurred at ca. 132 ka, in response to the development of the global deglacial phase. The major changes in trace element composition are coherent with the previous hydrological interpretation of speleothem oxygen stable isotope composition (δ18O) as predominantly a rainfall-amount proxy. However, reduced growth rate persisted until ca. 130 ka, suggesting still depressed temperatures. An abrupt event of climatic deterioration, with marked decrease in precipitation and soil degradation, is apparent between ca. 131 and 130 ka. Cool-wet conditions between ca. 132 and 131 ka and the subsequent dry period may represent the local hydrological response to an interval of North Atlantic cooling and ice-rafted-debris (IRD) deposition known as Heinrich event 11 (H11). After 129.6 ka there was a rapid recovery according to all of the studied speleothem properties, indicating the onset of full interglacial conditions. A minor amplitude event of reduced precipitation is recorded within the LIG at ca. 127 ka. The record highlights the growing regional evidence for a complex penultimate deglacial climate involving major reorganization of

    Aim of this work is to analyse the environmental quality of a small stream, the Fosso della Casaccia, flowing near Research Centre of ENEA (Rome, Central Italy). The study was carried out comparing zoo benthic communities of two sampling sites, chosen upstream and downstream the sewage of the Research Centre. Macro invertebrates were sampled using artificial substrates and standard hand net. Taxa number and distribution along along the watercourse were compared. Moreover, biotic index values (I.B.E.=Indice Biotico Esteso) were calculated using data on macro invertebrates collected with both sampling methodologies. Artificial substrates were also useful in establishing colonization patterns at each sampling site, and bio masses of individuals belonging to different trophic groups. The results show the greater sampling effectiveness of artificial substrates, confirming their usefulness for establishing the environmental quality. [Italiano] Il presente lavoro prende in considerazione la qualita` ambientale del Fosso della Casaccia, un piccolo corso d`acqua che scorre in prossimita` del Centro di Ricerche ENEA Casaccia (Italia Centrale). Lo studio e` stato realizzato in base al confronto fra le comunita` zoobentoniche di due stazioni sperimentali situate a monte e a valle dello scarico di acque reflue del centro.

    Abstract The Windjana drill sample, a sandstone of the Dillinger member (Kimberley formation, Gale Crater, Mars), was analyzed by CheMin X‐ray diffraction (XRD) in the MSL Curiosity rover. From Rietveld refinements of its XRD pattern, Windjana contains the following: sanidine (21% weight, ~Or95); augite (20%); magnetite (12%); pigeonite; olivine; plagioclase; amorphous and smectitic material (~25%); and percent levels of others including ilmenite, fluorapatite, and bassanite. From mass balance on the Alpha Proton X‐ray Spectrometer (APXS) chemical analysis, the amorphous material is Fe rich with nearly no other cations—like ferrihydrite. The Windjana sample shows little alteration and was likely cemented by its magnetite and ferrihydrite. From ChemCam Laser‐Induced Breakdown Spectrometer (LIBS) chemical analyses, Windjana is representative of the Dillinger and Mount Remarkable members of the Kimberley formation. LIBS data suggest that the Kimberley sediments include at least three chemical components. The most K‐rich targets have 5.6% K2O, ~1.8 times that of Windjana, implying a sediment component with >40% sanidine, e.g., a trachyte. A second component is rich in mafic minerals, with little feldspar (like a shergottite). A third component is richer in plagioclase and in Na2O, and is likely to be basaltic. The K‐rich sediment component is consistent with APXS and ChemCam observations of K‐rich rocks elsewhere in Gale Crater. The source of this sediment component was likely volcanic. The presence of sediment from many igneous sources, in concert with Curiosity's identifications of other igneous materials (e.g., mugearite), implies that the northern rim of Gale Crater exposes a diverse igneous complex, at least as diverse as that found in similar‐age terranes on Earth.

The group submitted for analysis includes jeweller’s dies used in the production of women’s ceremonial ornaments, crucibles and bronze ornaments. The Mongol invasion of 13th c. had caused craftsmen from central areas of East Europe to flee and seek shelter in the western parts of Rus. It may be safe to interpret the finds from Chełm as the remains of a jeweller’s workshop, the site of casting and working copper alloys and silver. The analysis of the technology used in casting copper alloys and silver in the jeweller’s workshop were made using optical microscopy, X-ray spectroscopy and X-ray radiography.

Il lavoro ripercorre in modo sintetico le principali iniziative istituzionali e le più note teorie di riferimento che le hanno accompagnate nell’ottica di favorire una consapevolezza storico-critica su ciò che l’esperienza ci può aver insegnato.

I risultati mostrano che per i settori tradizionali, che impiegano manodopera meno qualificata, il commercio internazionel tende ad influenzare negativamente i livelli salariali ed occupazionali, mentre per i settorui tecnologicamente piu' avanzati determina variazioni positive dei salari e dell'occupazioni.

  5. ‘Unkind and cruel, to deceive your Son | In borrow’d Shapes, and his Embrace to shun’: Mother-son love in T. S. Eliot’s ‘La Figlia Che Piange’

    2015-01-01

    Full Text Available T. S. Eliot's "La Figlia Che Piange" (1916 is a curious anomaly in his early works. It stands out as a love poem of outstanding grace portraying a more positive relationship to the feminine compared to other poems contemporaneous with its writing such as "The Love Song of St. Sebastian" (1914 and "Hysteria" (1915. This essay shows the import of Eliot's chosen epigraph for "La Figlia" taken from Virgil's Aeneid to have been largely neglected or misread by critics. As a consequence, it argues that critical readings have crucially missed the presence of a shrouded maternal aspect within the poem. Through the lens of Lacanian psychoanalysis and the work of adherents to Lacanian theory — such as Bruce Fink, Shoshana Felman and Slavoj Zizek — this paper newly argues that the poem's meditation on the issues of union and separation between two lovers is in fact a screen for deeper unconscious ambivalent feelings between mother and son. That is to say, Eliot's "La Figlia Che Piange" shows a failed attempt to reconstruct, traverse and separate from the "fundamental fantasy" unconsciously orientating the male speaker of the poem and his desire.

    Full Text Available Nell'ultimo decennio il mondo dei media è€ cambiato, così€ come è€ cambiato il modo in cui i soggetti imparano ad avvalersi della comunicazione per confrontarsi con la realtà€. L'exploit tecnologico della modernizzazione ha contribuito a modificare la cornice socio-culturale, trasformando il profilo dei giovani, i loro stili di vita e le loro abitudini, i loro modi di essere, di pensare e di comportarsi nel quotidiano. Questo senso di cambiamento nell'epoca moderna è€ da molto tempo oggetto di un dibattito scientifico che si sviluppa fra preoccupazioni e perplessità€, fra timori e nuove opportunità di socializzazione. Così€ l'innovazione e la “corsa” tecnologica, se da un lato consentono una democratizzazione culturale, per l’aumento delle opportunità€ di accesso alla 'competenza' comunicativa, dall’altro segnano inevitabilmente nuovi divari e gap socioculturali. Per capire l'intensità, la radicalità€ e il senso dei mutamenti che stiamo attraversando è€ opportuno cominciare ad esplorare i territori di interazione fra processi formativi e percorsi di comunicazione, soprattutto riguardo all’universo giovanile.

    Centralized plant of `Ponte a Cappiano` (Florence. Italy), managed by `Consorzio Conciatori` of Fucecchio, treat effluent of 45 tanneries and little rate of municipal wastes. Particular attention must be lay to reduction of the sulphide that daily come to the plant in addition to complexity and load amount especially in terms of COD, suspended solid, ammonia and other compounds. The critical point of wastewater treatment plants is the transformation of sulphide to inert compound both chemical and odourless. More of a year of working experience, through management modification, allowed to solve this problem by conversion on sulphide or sulphur. In a batch running compartment working like a chemical reactor, this is possible, through the treatment of wastewater rate having high ph values and containing the largest sulphide amount with liquid oxygen, manganese catalyst and checking ph. [Italiano] L`impianto di depurazione centralizzato di Ponte a Cappiano gestito dal Consorzio Conciatori di Fucecchio, tratta gli scarichi liquidi di 45 aziende conciarie ed un`aliquota modesta di liquami civili di parte del territorio comunale. Oltre alla complessita` ed alla quantita` del carico inquinante in ingresso relativamente alla COD, ai solidi sospesi, all`ammoniaca ed ad altri composti, particolare attenzione deve essere posta per l`abbattimento dei solfuri che giornalmente arrivano all`impianto in quantita` variabili da 600 a 1.000 kg circa. La trasformazione di questo inquinante in composti inerti, sia sotto il profilo chimico che sotto il profilo delle maleodoranze, ha da sempre rappresentato il nodo critico del processo di depurazione di questo tipo di liquame. L`esperienza di oltre un anno effettuata sull`impianto, attraverso modificazioni gestionali, ha consentito di risolvere il problema dell`abbattimento dei solfuri, con l`impiego dell`ossigeno liquido, catalizzatore a base di manganese e controllo del pH in un comparto funzionante in discontinuo come un vero e proprio

    Full Text Available Mauro Cardi addresses the implications of the development of technologies and networking on the ‘work’ of the composer and the influence they exert on the modalities of ‘generation’, reception and fruition of musical texts, both in terms of social impact, and of mechanisms and practices they produce. Where the greater availability of resources proves to offer opportunities hard to imagine before, the problems that are created extend their range. It therefore remains the inescapable need for the composer to design his own instruments, in order to maintain a fully active role in the choices required by his work.

They do not require any cooking or reheating before consumption. They were prescribed with a one-month shelflife at ambient storage temperature (28±2°C during deployment as relief foods. About 5,000 and 3,000 production units of the RTE cooked rice (200 g/pack and bihon (150 g/pack, respectively, were produced at the PFP. Around 300 volunteers composed of faculty, staff, alumni, students, and acquaintances of UPD-CHE’s departments and organizations manned the two-week staggered production, scheduled from late November to the f irst week of December 2013. In cooperation with organizations and private entities, the RTE products were deployed without cost from UPD to the stricken areas of Aklan, Iloilo, and Leyte. Feedback from the recipients of the products was favorable, indicating that the RTE foods are useful as emergency relief ration.

    In vivo-induced antigen technology is a method to identify proteins expressed by pathogenic bacteria during human infection. Sera from 10 patients convalescing from cholera infection in Bangladesh were pooled, adsorbed against in vitro-grown El Tor Vibrio cholerae O1, and used to probe a genomic expression library in Escherichia coli constructed from El Tor V. cholerae O1 strain N16961. We identified 38 positive clones in the screen, encoding pili (PilA and TcpA), cell membrane proteins (PilQ, MshO, MshP, and CapK), methyl-accepting chemotaxis proteins, chemotaxis and motility proteins (CheA and CheR), a quorum-sensing protein (LuxP), and four hypothetical proteins. Analysis of immune responses to purified PilA and TcpA in individual patients demonstrated that the majority seroconverted to these proteins, confirming results with pooled sera. These results suggest that PilA and its outer membrane secretin, PilQ, are expressed during human infection and may be involved in colonization of the gastrointestinal tract. These results also demonstrate substantial immune responses to TcpA in patients infected with El Tor V. cholerae O1. In vivo-induced antigen technology provides a simple method for identifying microbial proteins expressed during human infection, but not during in vitro growth.

    2010-01-01

    The National Institute for Health and Clinical Excellence (NICE) invited the manufacturer of alitretinoin (Basilea Pharmaceuticals Ltd, Basel, Switzerland) to submit evidence for the clinical and cost effectiveness of this drug for the treatment of patients with severe chronic hand eczema (CHE), as part of the Institute's single technology appraisal (STA) process. The Centre for Reviews and Dissemination and the Centre for Health Economics at the University of York were commissioned to act as the Evidence Review Group (ERG). This article provides a description of the company submission, the ERG review and NICE's subsequent decisions. The ERG produced a critical review of the evidence for the clinical and cost effectiveness of the technology based upon the manufacturer's submission to NICE. The ERG also independently searched for relevant evidence and modified the manufacturer's decision analytic model to examine the impact of altering some of the key assumptions. The main clinical effectiveness data were derived from a single-placebo randomized controlled trial (RCT) of daily treatment with alitretinoin for 12-24 weeks, with follow-up for a further 24 weeks, in patients with severe CHE unresponsive to topical corticosteroids. A significantly greater proportion of patients achieved 'clear' or 'almost clear' hands by week 24 with alitretinoin than those using placebo: 48% with alitretinoin 30 mg (p < 0.001); 28% with alitretinoin 10 mg (p < 0.005); 17% with placebo. Most patients who responded remained in remission during the 24-week follow-up period. The most commonly reported adverse event was dose-dependent headache, with rates of 20% in the alitretinoin 30 mg group and 11% in the alitretinoin 10 mg group, respectively. Serious adverse events were rare, although alitretinoin was associated with increases in both total cholesterol and triglycerides. No direct or indirect comparisons of alitretinoin with any of the relevant treatment comparators (psoralen + UVA

    Full Text Available Il saggio presenta alcuni risultati dell’indagine archivistica condotta sulle filze Savoia del fondo Mediceo del Principato dell’Archivio di Stato di Firenze. I documenti, letti criticamente e selezionati attraverso una prospettiva storico artistica, permettono di mettere in luce nuovi aspetti della figura dell’ingegnere livornese Donato Rossetti, il quale svolge il ruolo di intermediario informativo artistico tra Torino e Firenze. Attraverso suoi dispacci da Torino e missive inviate da Francesco Bondicchi da Milano a Firenze emergono sia alcuni aspetti inediti delle relazioni tra le due corti, sia il rapporto biunivoco tra centri e periferie che si precisa nel corso del Seicento. A metà secolo il ruolo di modello svolto da Firenze fa sentire ancora la propria influenza al di fuori dei confini del granducato e contemporaneamente Firenze guarda con vivo interesse alla scena artistica e urbanistica torinese. Relations between the Savoia and the Florentine court were very intense during the early modern age. Almost every day, diplomatics and residents in the Savoia court sent letters and avvisi to Florence by revealing interesting details on the everyday life and by shedding light on a range of relevant political, diplomatic, familiar and artistic dynamics. Florentine ambassadors’ or intermediaries’ reports - such as Donato Rossetti’s letters - focus on the first concern of the Savoia court, after settling in Turin, that was to build a fortified citadel and to redraw the plan of the city. During my systematic analysis of Florentine court documents at the Florence State Archive, I uncovered compelling evidence of these intricate affairs regarding the rebuilding of Turin, and these unpublished documents shed new light both on the expansion of the city and on relations between Savoia and Medici courts. This paper provide evidence to suggest that Florence was considered by the Savoy Court as the leading innovator in visual arts and

    humide des fumées, le procédé de désulfuration par voie sèche reste un moyen attractif pour éliminer le dioxyde de soufre lorsque le taux de réduction souhaité ne dépasse pas 90 %. Dans cette technique, l'élimination du SO2 se fait en injectant directement dans les produits de combustion de très fines particules d'un absorbant calcique tel que le calcaire (CaCO3 ou la chaux (Ca(OH². L'absorbant est tout d'abord transformé en oxyde de calcium (CaO avant de réagir avec le SO2 pour former un composé stable : le sulfate de calcium (CaSO4. Bien que les réactions globales soient extrêmement simples, une description complète des mécanismes nécessite de connaître à la fois, les propriétés physiques initiales de l'absorbant et leur évolution durant la réaction. De plus, les conditions d'injection des particules jouent un rôle prépondérant dans le procédé de désulfuration par voie sèche. Tous ces aspects sont traités dans ce papier. Le modèle de désulfuration a d'abord été testé seul par comparaison avec les données cinétiques de la Fondation Internationale de Recherches sur les Flammes (FRIF, puis, couplé avec le code KIVA, il a été utilisé pour simuler la désulfuration dans un nouveau type de chaudière développée par Babcock Entreprise et l'Institut Français du Pétrole (chaudière 'AUDE'. Dans ce dernier cas, l'objectif poursuivi était de déterminer la meilleure configuration à donner au système d'injection des particules pour obtenir un taux de désulfuration maximum. La dispersion des particules étant un paramètre important du procédé de désulfuration, un exemple de validation du modèle de dispersion est également traité. L'injection de particules dans une couche de mélange a été choisie comme cas test. L'accord entre les valeurs expérimentales de Ando et al. (1990 et les calculs effectués avec KIVA est satisfaisant.

    Full Text Available In this paper I have analysed the characteristics of what I define the “gambling subculture”, which is detectable in certain gaming environments and in subgroups of particularly “rabid” players. Within these subcultures there have been identified rules and sanctions, values, consolidate behaviours, characterization of relationships and interactions, and the conclusion is that what is built within the gambling environment is a separate universe, an “outer reality”, in which the values of the world “outside” change. It was also possible to conclude that, to join the gambling world for a gambler – learning its rules, sharing its values, developing relations inside it – represents a stimulus for gambling habits, as it allows to consider as “normal” their behaviour thanks to positive feedback from their groups of fellow players, and to the neutralization of possible negative feedback from “non-players”.Nel presente contributo vengono analizzate le caratteristiche di quella che ho definito “subcultura dell'azzardo”, rilevabile in determinati ambienti ludici e in sotto-gruppi di giocatori particolarmente “accaniti”. Di queste forme di subcultura sono state individuate norme e sanzioni, valori, comportamenti consolidati, caratterizzazione delle relazioni e delle interazioni, giungendo alla conclusione che quello che viene costruito negli spazi di gioco rappresenta un universo separato, un “extraluogo”, nel quale vengono scritte nuove regole e nel quale cambiano i valori rispetto al mondo “esterno”. È stato possibile inoltre concludere che l'adesione all'“universo gioco” – l'interiorizzazione delle sue norme, la condivisione dei suoi valori, lo sviluppo di relazioni al suo interno – rappresenta un fattore di mantenimento della condotta ludica, poiché permette di considerare “normale” il proprio comportamento grazie ai rinforzi positivi che giungono dal gruppo dei compagni-giocatori e alla

    With 'Banana Technology' an unconventional hybrid fabrication technology is indicated for the production of very large parabolic and hyperbolic cylindrical mirror systems. The banana technology uses elastic bending of very large and thin glass substrates and fixation onto NC milled metal moulds. This technology has matured during the last twenty years for the manufacturing of large telecentric flat-bed scanners. Two construction types, called 'internal banana' and 'external banana; are presented. Optical figure quality requirements in terms of slope and curvature deviations are discussed. Measurements of these optical specifications by means of a 'finishing rod' type of scanning deflectometer or slope tester are presented. Design constraints for bending glass and the advantages of a new process will be discussed.

The specific goals continue to be to (1) develop an understanding of fundamental fabrication processes; (2) construct general purpose process models that will have wide applicability; (3) document findings and models in journals; (4) transfer technology to LLNL programs, industry, and colleagues; and (5) develop continuing relationships with the industrial and academic communities to advance the collective understanding of fabrication processes. The strategy to ensure success is changing. For technologies in which they are expert and which will continue to be of future importance to LLNL, they can often attract outside resources both to maintain their expertise by applying it to a specific problem and to help fund further development. A popular vehicle to fund such work is the Cooperative Research and Development Agreement with industry. For technologies needing development because of their future critical importance and in which they are not expert, they use internal funding sources. These latter are the topics of the thrust area.

    Cet article a pour objet de proposer une nouvelle procédure pour classer les tâches motrices à caractère informationnel à partir d’une approche multidimensionnelle de la difficulté. L’expérimentation a consisté à faire passer des tests de pointage à 345 sujets sur cibles mobiles créées et gérées par ordinateur. Les paramètres des cibles ont été choisis pour leur indépendance et la possibilité de les positionner sur des échelles numériques. Trois descripteurs ont été retenus : la vitesse de déplacement, la surface de la cible et l’incertitude spatiale. La performance ne semblant pas être la seule variable dépendante résumant la difficulté, il lui a été adjoint trois autres variables : les tentatives, le temps de réaction et le temps moteur. En utilisant des outils statistiques permettant des analyses de données multidimensionnelles (CAH, AFC, il a été possible soit d’agréger des tâches aux profils identiques soit de les différencier en fonction du poids de chaque descripteur sur les variables dépendantes. Surtout, il est envisageable de préciser l’apport de chaque variable dans la définition de la difficulté que se donne a posteriori le chercheur.

    The objective of this summer's work was to attempt to enhance Technology Application Group (TAG) ability to measure the outcomes of its efforts to transfer NASA technology. By reviewing existing literature, by explaining the economic principles involved in evaluating the economic impact of technology transfer, and by investigating the LaRC processes our William & Mary team has been able to lead this important discussion. In reviewing the existing literature, we identified many of the metrics that are currently being used in the area of technology transfer. Learning about the LaRC technology transfer processes and the metrics currently used to track the transfer process enabled us to compare other R&D facilities to LaRC. We discuss and diagram impacts of technology transfer in the short run and the long run. Significantly, it serves as the basis for analysis and provides guidance in thinking about what the measurement objectives ought to be. By focusing on the SBIR Program, valuable information regarding the strengths and weaknesses of this LaRC program are to be gained. A survey was developed to ask probing questions regarding SBIR contractors' experience with the program. Specifically we are interested in finding out whether the SBIR Program is accomplishing its mission, if the SBIR companies are providing the needed innovations specified by NASA and to what extent those innovations have led to commercial success. We also developed a survey to ask COTR's, who are NASA employees acting as technical advisors to the SBIR contractors, the same type of questions, evaluating the successes and problems with the SBIR Program as they see it. This survey was developed to be implemented interactively on computer. It is our hope that the statistical and econometric studies that can be done on the data collected from all of these sources will provide insight regarding the direction to take in developing systematic evaluations of programs like the SBIR Program so that they can

  13. Vacuum Technology

    Energy Technology Data Exchange (ETDEWEB)

    Biltoft, P J

    2004-10-15

    The environmental condition called vacuum is created any time the pressure of a gas is reduced compared to atmospheric pressure. On earth we typically create a vacuum by connecting a pump capable of moving gas to a relatively leak free vessel. Through operation of the gas pump the number of gas molecules per unit volume is decreased within the vessel. As soon as one creates a vacuum natural forces (in this case entropy) work to restore equilibrium pressure; the practical effect of this is that gas molecules attempt to enter the evacuated space by any means possible. It is useful to think of vacuum in terms of a gas at a pressure below atmospheric pressure. In even the best vacuum vessels ever created there are approximately 3,500,000 molecules of gas per cubic meter of volume remaining inside the vessel. The lowest pressure environment known is in interstellar space where there are approximately four molecules of gas per cubic meter. Researchers are currently developing vacuum technology components (pumps, gauges, valves, etc.) using micro electro mechanical systems (MEMS) technology. Miniature vacuum components and systems will open the possibility for significant savings in energy cost and will open the doors to advances in electronics, manufacturing and semiconductor fabrication. In conclusion, an understanding of the basic principles of vacuum technology as presented in this summary is essential for the successful execution of all projects that involve vacuum technology. Using the principles described above, a practitioner of vacuum technology can design a vacuum system that will achieve the project requirements.

    The technology activities carried out by the Euratom-ENEA Association in the framework of the European Fusion Development Agreement concern the Next Step (International Thermonuclear Experimental Reactor - ITER), the Long-Term Programme (breeder blanket, materials, International Fusion Materials Irradiation Facility - IFMIF), Power Plant Conceptual Studies and Socio-Economic Studies. The Underlying Technology Programme was set up to complement the fusion activities as well to develop technologies with a wider range of interest. The Technology Programme mainly involves staff from the Frascati laboratories of the Fusion Technical and Scientific Unit and from the Brasimone laboratories of the Advanced Physics Technologies Unit. Other ENEA units also provide valuable contributions to the programme. ENEA is heavily engaged in component development/testing and in design and safety activities for the European Fusion Technology Programme. Although the work documented in the following covers a large range of topics that differ considerably because they concern the development of extremely complex systems, the high level of integration and coordination ensures the capability to cover the fusion system as a whole. In 2004 the most significant testing activities concerned the ITER primary beryllium-coated first wall. In the field of high-heat-flux components, an important achievement was the qualification of the process for depositing a copper liner on carbon fibre composite (CFC) hollow tiles. This new process, pre-brazed casting (PBC), allows the hot radial pressing (HRP) joining procedure to be used also for CFC-based armour monoblock divertor components. The PBC and HRP processes are candidates for the construction of the ITER divertor. In the materials field an important milestone was the commissioning of a new facility for chemical vapour infiltration/deposition, used for optimising silicon carbide composite (SiCf/SiC) components. Eight patents were deposited during 2004

    Research results of hard photon technology have been summarized as a part of novel technology development highly utilizing the quantum nature of photon. Hard photon technology refers to photon beam technologies which use photon in the 0.1 to 200 nm wavelength region. Hard photon has not been used in industry due to the lack of suitable photon sources and optical devices. However, hard photon in this wavelength region is expected to bring about innovations in such areas as ultrafine processing and material synthesis due to its atom selective reaction, inner shell excitation reaction, and spatially high resolution. Then, technological themes and possibility have been surveyed. Although there are principle proposes and their verification of individual technologies for the technologies of hard photon generation, regulation and utilization, they are still far from the practical applications. For the photon source technology, the laser diode pumped driver laser technology, laser plasma photon source technology, synchrotron radiation photon source technology, and vacuum ultraviolet photon source technology are presented. For the optical device technology, the multi-layer film technology for beam mirrors and the non-spherical lens processing technology are introduced. Also are described the reduction lithography technology, hard photon excitation process, and methods of analysis and measurement. 430 refs., 165 figs., 23 tabs.

    Wearable technology projects, to be useful, in the future, must be seamlessly integrated with the Flight Deck of the Future (F.F). The lab contains mockups of space vehicle cockpits, habitat living quarters, and workstations equipped with novel user interfaces. The Flight Deck of the Future is one element of the Integrated Power, Avionics, and Software (IPAS) facility, which, to a large extent, manages the F.F network and data systems. To date, integration with the Flight Deck of the Future has been limited by a lack of tools and understanding of the Flight Deck of the Future data handling systems. To remedy this problem it will be necessary to learn how data is managed in the Flight Deck of the Future and to develop tools or interfaces that enable easy integration of WEAR Lab and EV3 products into the Flight Deck of the Future mockups. This capability is critical to future prototype integration, evaluation, and demonstration. This will provide the ability for WEAR Lab products, EV3 human interface prototypes, and technologies from other JSC organizations to be evaluated and tested while in the Flight Deck of the Future. All WEAR Lab products must be integrated with the interface that will connect them to the Flight Deck of the Future. The WEAR Lab products will primarily be programmed in Arduino. Arduino will be used for the development of wearable controls and a tactile communication garment. Arduino will also be used in creating wearable methane detection and warning system.

    Waste incineration is the art of completely combusting waste, while maintaining or reducing emission levels below current emission standards. Where possible, objectives include the recovering of energy as well as the  combustion residues.  Successful waste incineration makes it possible to achieve a deep reduction in waste volume, obtain a compact and sterile residue, and eliminate a wide array of pollutants. This book places waste incineration within the wider context of waste management, and demonstrates that, in contrast to landfills and composting, waste incineration can eliminate objectionable and hazardous properties such as flammability and toxicity, result in a significant reduction in volume, and destroy gaseous and liquid waste streams leaving little or no residues beyond those linked to flue gas neutralization and treatment. Moreover, waste incineration sterilizes and destroys putrescible matter, and produces usable heat.  Incineration Technologies first appeared as a peer-reviewed contribution ...

Solar energy, wind energy, different thermal and hydro sources of energy, biogas are all renewable energy resources. But, biogas is distinct from other renewable energies because of its characteristics of using, controlling and collecting organic wastes and at the same time producing fertilizer and water for use in agricultural irrigation. Biogas does not have any geographical limitations nor does it require advanced technology for producing energy, also it is very simple to use and apply. Anaerobic digestion is controlled biological degradation process which allows efficient capturing & utilization of biogas (approximately 60% methane and 40% carbon dioxide for energy generation. Anaerobic digestion of food waste is achievable but different types, composition of food waste results in varying degrees of methane yields, and thus the effects of mixing various types of food waste and their proportions should be determined on case by case basis.

CMM data analysis and delivery were enhanced through the addition of several machine types to the inspection summary program. CMM hardware and software improvements were made with the purchases of calibration and setup equipment and new model-based software for the creation of inspection programs. Kansas City Plant (KCP) personnel contributed to and influenced the development of dimensional metrology standards. Model-based engineering capabilities were expanded through the development of software for the tolerance analysis of piece parts and for the creation of model-based CMM inspection programs and inspection plans and through the purchase of off-the-shelf software for the tolerance analysis of mechanical assemblies. An obsolete database application used to track jobs in Precision Measurement was replaced by a web-based application with improved query and reporting capabilities. A potential project to address the transformation of the dimensional metrology enterprise at the Kansas City Plant was identified.

    For developing laser process technology by interaction between substance and photon, the present state, system, R and D issues and proposal of such technology were summarized. Development of the photon technology aims at the modification of bonding conditions of substances by quantum energy of photon, and the new process technology for generating ultra- high temperature and pressure fields by concentrating photon on a minute region. Photon technology contributes to not only the conventional mechanical and thermal forming and removal machining but also function added machining (photon machining) in quantum level and new machining technology ranging from macro- to micro-machining, creating a new industrial field. This technology extends various fields from the basis of physics and chemistry to new bonding technology. Development of a compact high-quality high-power high-efficiency photon source, and advanced photon transmission technology are necessary. The basic explication of an unsolved physicochemical phenomenon related to photon and substance, and development of related application technologies are essential. 328 refs., 147 figs., 13 tabs.

Having examinedthe results of the previous researches, the theoretical framework that would light the way for the research was prepared. Theavailable information about the subject was scanned from resources such as documents, other written sources and also theinternet, and expert’s opinions were asked for. The content analysis of the collected information was done.The preschool period is a process to which all education scientists attach great importance. However, in order to realize theaim of this process, well planned education programmes are needed. The preschool education period provides crèche,nursery and reception education activities. Because of the annual changes of education technologies, positive differences areseen for the teaching activities in this area. On the other hand, there are some requirements to do to speed up the educationand to increase the productivity of education in our present day information society.The preschool education programmes are “the Crèche Programme (0-36 months”, “The Nursery Programme (37-60months and “The Reception Programme (61-72 months”.

  18. Fundamentals of technology roadmapping

    Energy Technology Data Exchange (ETDEWEB)

    Garcia, M.L.; Bray, O.H.

    1997-04-01

    Technology planning is important for many reasons. Globally, companies are facing many competitive problems. Technology roadmapping, a form of technology planning can help deal with this increasingly competitive environment. While it has been used by some companies and industries, the focus has always been on the technology roadmap as a product, not on the process. This report focuses on formalizing the process so that it can be more broadly and easily used. As a DOE national security laboratory with R&D as a major product, Sandia must do effective technology planning to identify and develop the technologies required to meet its national security mission. Once identified, technology enhancements or new technologies may be developed internally or collaboratively with external partners. For either approach, technology roadmapping, as described in this report, is an effective tool for technology planning and coordination, which fits within a broader set of planning activities. This report, the second in a series on technology roadmapping, develops and documents this technology roadmapping process, which can be used by Sandia, other national labs, universities, and industry. The main benefit of technology roadmapping is that it provides information to make better technology investment decisions by identifying critical technologies and technology gaps and identifying ways to leverage R&D investments. It can also be used as a marketing tool. Technology roadmapping is critical when the technology investment decision is not straight forward. This occurs when it is not clear which alternative to pursue, how quickly the technology is needed, or when there is a need to coordinate the development of multiple technologies. The technology roadmapping process consists of three phases - preliminary activity, development of the technology roadmap, and follow-up activity.

    2013-03-01

    The National Institute for Health and Clinical Excellence (NICE) invited the manufacturer of trastuzumab, Roche Pharmaceuticals, to submit evidence for the clinical and cost effectiveness of this drug for the treatment of advanced gastric cancer (aGC), as part of the Institute's single technology appraisal (STA) process. The Centre for Reviews and Dissemination (CRD) and the Centre for Health Economics (CHE) Technology Appraisal Group at the University of York was commissioned to act as the evidence review group (ERG). This article provides a description of the company submission, the ERG report and NICE's subsequent decisions. In the initial appraisal by NICE, trastuzumab was rejected for use in the licensed population. Given this result, the manufacturer submitted additional evidence. In the final appraisal decision, trastuzumab was approved, in accordance with supplementary guidance issued by NICE on appraising life-extending, end-of-life treatments, for patients whose human epidermal growth factor receptor 2 (HER2) status was defined by an immunohistochemistry 3 positive (IHC3+) result. This appraisal highlights the need to fully assess the impact of different approaches to diagnostic testing on the cost effectiveness of targeted treatments. In this appraisal, it was found that the diagnostic strategy influenced the effectiveness and cost of trastuzumab. In the future, different diagnostic strategies should be compared in the incremental cost-effectiveness analysis.

    Directory of Open Access Journals (Sweden)

    Saulius Kanišauskas

    2015-10-01

    Full Text Available The paper analyses different attitudes towards technologies in contemporary philosophical discourses. It points out that classical notion of technology formulated by Martin Heidegger seems to be more and more often questioned and even forgotten. As a result, it is being replaced by the theory of determinism, according to which the change of technologies determines the changes in social systems, the human being including. This happens this way and not vice versa. Nowadays technē, or “technika” (in English: technology is mostly understood in the instrumental meaning or in the meaning of power. It is considered to be a powerful means, tool or mechanism to influence, change, control and manipulate human consciousness and human feelings. Despite the fact that technologies have already been tamed, the problem of huge responsibility for using and developing them arises. It is questioned whether the increasing society’s attention to modern technologies is not a particular “technology” of the postmodern capitalism to manipulate social consciousness. In parallel with “yes” answer to this question, Albert Borgmann’s idea that the causes of technological development have an ontological dimension, i.e. the causes are rooted in the nature of human beings themselves and their desire to adore own creativity, is discussed. Thus, it becomes necessary to probe deeper into the nature of creativity.

    Piezoelectric ultrasonic transducers (UTs) are used for real-time, in-situ or off-line nondestructive evaluation (NDE) of large metallic structures such as airplanes, automobiles, ships, pressure vessels and pipelines because of their subsurface inspection capability, fast inspection speed, simplicity and cost-effectiveness. The objective of this study was to develop and evaluate effective integrated ultrasonic transducers (IUT) technology to perform non-intrusive engine NDE and structural health monitoring (SHM). High temperature IUTs made of bismuth titanate piezoelectric film greater than 50 {mu}m in thickness were coated directly onto a modified CF700 turbojet engine outer casing, oil sump and supply lines and gaskets using sol-gel spray technology. The assessment was limited to temperatures up to 500 degrees C. The center frequencies of the IUTs were approximately 10 to 17 MHz. Ultrasonic signals obtained in pulse/echo measurements were excellent. High temperature ultrasonic performance will likely be obtained in the transmission mode as well. The potential applications of the developed IUTs include non-intrusive real-time temperature, lubricant oil quality and metal debris monitoring within a turbojet engine environment. 9 refs., 13 figs.

    Technology alone will not be able to solve adaptation challenges, but it is likely to play an important role. As a result of the role of technology in adaptation and the importance of international collaboration for climate change, technology transfer for adaptation is a critical but understudied issue. Through an analysis of Global Environment Facility-managed adaptation projects, we find there is significantly more technology transfer occurring in adaptation projects than might be expected given the pessimistic rhetoric surrounding technology transfer for adaptation. Most projects focused on demonstration and early deployment/niche formation for existing technologies rather than earlier stages of innovation, which is understandable considering the pilot nature of the projects. Key challenges for the transfer process, including technology selection and appropriateness under climate change, markets and access to technology, and diffusion strategies are discussed in more detail.

    2005-01-27

    Lawrence Livermore National Laboratory's Engineering Directorate has two primary discretionary avenues for its investment in technologies: the Laboratory Directed Research and Development (LDRD) program and the ''Tech Base'' program. This volume summarizes progress on the projects funded for technology-base efforts in FY2004. The Engineering Technical Reports exemplify Engineering's more than 50-year history of researching and developing (LDRD), and reducing to practice (technology-base) the engineering technologies needed to support the Laboratory's missions. Engineering has been a partner in every major program and project at the Laboratory throughout its existence, and has prepared for this role with a skilled workforce and technical resources. This accomplishment is well summarized by Engineering's mission: ''Enable program success today and ensure the Laboratory's vitality tomorrow''. LDRD is the vehicle for creating those technologies and competencies that are cutting edge. These require a significant level of research or contain some unknown that needs to be fully understood. Tech Base is used to apply those technologies, or adapt them to a Laboratory need. The term commonly used for Tech Base projects is ''reduction to practice''. Tech Base projects effect the natural transition to reduction-to-practice of scientific or engineering methods that are well understood and established. They represent discipline-oriented, core competency activities that are multi-programmatic in application, nature, and scope. The objectives of technology-base funding include: (1) the development and enhancement of tools and processes to provide Engineering support capability, such as code maintenance and improved fabrication methods; (2) support of Engineering science and technology infrastructure, such as the installation or integration of a new capability; (3) support for technical and

    Survey has been conducted to develop laser processing technology utilizing the interaction between substance and photon. This is a part of the leading research on photon technology development. The photon technology development is aimed at novel technology development highly utilizing the quantum nature of photons. In the field of laser processing, high quality photons are used as tools, special functions of atoms and molecules will be discovered, and processing for functional fabrication (photon machining) will be established. A role of laser processing in industries has become significant, which is currently spreading not only into cutting and welding of materials and scalpels but also into such a special field as ultrafine processing of materials. The spreading is sometimes obstructed due to the difficulty of procurement of suitable machines and materials, and the increase of cost. The purpose of this study is to develop the optimal laser technology, to elucidate the interaction between substance and photon, and to develop the laser system and the transmission and regulation systems which realize the optimal conditions. 387 refs., 115 figs., 25 tabs.

    For the application of photon to industrial technologies, in particular, a hard photon technology was surveyed which uses photon beams of 0.1-200nm in wavelength. Its features such as selective atom reaction, dense inner shell excitation and spacial high resolution by quantum energy are expected to provide innovative techniques for various field such as fine machining, material synthesis and advanced inspection technology. This wavelength region has been hardly utilized for industrial fields because of poor development of suitable photon sources and optical devices. The developmental meaning, usable time and issue of a hard photon reduction lithography were surveyed as lithography in ultra-fine region below 0.1{mu}m. On hard photon analysis/evaluation technology, the industrial use of analysis, measurement and evaluation technologies by micro-beam was viewed, and optimum photon sources and optical systems were surveyed. Prediction of surface and surface layer modification by inner shell excitation, the future trend of this process and development of a vacuum ultraviolet light source were also surveyed. 383 refs., 153 figs., 17 tabs.

  1. Advanced manufacturing: Technology diffusion

    Energy Technology Data Exchange (ETDEWEB)

    Tesar, A.

    1995-12-01

    In this paper we examine how manufacturing technology diffuses rom the developers of technology across national borders to those who do not have the capability or resources to develop advanced technology on their own. None of the wide variety of technology diffusion mechanisms discussed in this paper are new, yet the opportunities to apply these mechanisms are growing. A dramatic increase in technology diffusion occurred over the last decade. The two major trends which probably drive this increase are a worldwide inclination towards ``freer`` markets and diminishing isolation. Technology is most rapidly diffusing from the US In fact, the US is supplying technology for the rest of the world. The value of the technology supplied by the US more than doubled from 1985 to 1992 (see the Introduction for details). History shows us that technology diffusion is inevitable. It is the rates at which technologies diffuse to other countries which can vary considerably. Manufacturers in these countries are increasingly able to absorb technology. Their manufacturing efficiency is expected to progress as technology becomes increasingly available and utilized.

The term technology is used here to describe any design choice for energy efficiency, ranging from individual components to more complex systems to general design strategies. The purpose of this task is to characterize the state of the art in envelope and lighting technologies in order to identify those with promise for advanced integrated systems, with an emphasis on California commercial buildings. For each technology category, the following activities have been attempted to the extent possible: Identify key performance characteristics and criteria for each technology; determine the performance range of available technologies; identify the most promising technologies and promising trends in technology advances; examine market forces and market trends; and develop a continuously growing in-house database to be used throughout the project. A variety of information sources have been used in these technology characterizations, including miscellaneous periodicals, manufacturer catalogs and cut sheets, other research documents, and data from previous computer simulations. We include these different sources in order to best show the type and variety of data available, however publication here does not imply our guarantee of these data. Within each category, several broad classes are identified, and within each class we examine the generic individual technologies that fag into that class.

    Troncy, Eric

    2012-01-01

    Conçu comme “une exposition dans un livre”, et présenté comme devant jouer un “rôle de biennale d’art contemporain”, Fresh Cream fait suite à Cream, également publié par les éditions Phaidon en 1998. Sur le même principe, le livre rassemble 100 artistes choisis par personne en particulier, plus exactement par dix commissaires en général. Le tout forme forcément un résultat impersonnel, et permet de vérifier une fois encore le vieil adage qui veut que « un dromadaire, c’est un cheval dessiné p...

  12. Le parole che noi usiamo: l’errore in storia

    Directory of Open Access Journals (Sweden)

    Aurelio Musi

    2017-04-01

    Full Text Available Unlike the hard sciences, historiography lacks a specific nomenclature. The lexicon employed by historians is drawn from the plain language of everyday life. Therefore, the words of history are to be defined within the spatio-temporal framework, and to be construed through processes of contextualization and comparison. My work here stems from these considerations, and attempts to chart the occurrence of errors in historiography. In particular, I take into account the way in which historiographic mistakes arise from the intermingling of words, space, and historical time. Another significant aspect concerns the relationship between history, fiction, and arbitrariness. The latter concept is linked to historical interpretation, which constitutes the last stage of historiographical work, after the analysis and the reconstruction of events. The last part of this paper offers a typology of frequent errors in historiography.

    Directory of Open Access Journals (Sweden)

    2012-12-01

    Full Text Available As it is well known an historical comprehension of the time in which people live and philosophers work is something essential in order to outline a theory that could grasps something of the world. The history of the relationship between art and philosophy is almost as old as philosophy itself. Among the first to take up the topic was Plato who posed the question in the most classical of ways—that is, by facing the problem of definition. The question of definition is nowadays deeply debated by philosophy of art and ontology. The paper address the problem of the definition suggesting a proposal which synthesizes ontology, epistemology and theory of perception.

    2012-11-01

    Full Text Available The article discusses the contribution by Aldo Montesano in this number, with a special focus on the definitions of economics and of political economy. In trying to answer if economics is a moral discipline and if it is a science, the article highlights that different schools of economists have interpreted and defined differently what economics is concerned with. It is pointed out that none of these approaches was born and is now dead, but rather different perspectives still coexist. For this reason, it is important on the one hand to allow for pluralism and on the other not to endorse caricatured representations of the discipline.  JEL Codes: A13, B00, A12Keywords: Definition of economics, moral values, schools of economics

  14. CHE COSA RESTA DI CHERUBINI OGGI? DUE CASI DI STUDIO

    Directory of Open Access Journals (Sweden)

    Emanuele Miola

    2016-09-01

    Full Text Available A partire dagli anni Duemila, il fenomeno delle cosiddette risorgenze dialettali si è manifestato, nel panorama linguistico italiano, anche attraverso l’emergenza dei dialetti negli ambiti propri della Comunicazione Mediata dal Computer e, specialmente, sui siti internet creati ‘dal basso’, come l’enciclopedia libera e multilingue online Wikipedia. In questo articolo, si esaminerà il lascito di Cherubini e del suo Vocabolario milanese-italiano sull’edizione regionale lombarda della Wikipedia: gli articoli di quest’ultima saranno passati in rassegna, sia dal punto di vista ortografico, comparando le scelte del lessicografo milanese con quelle più in voga online, sia dal punto di vista morfo-sintattico, discutendo in questo secondo caso la presenza e la produttività di alcuni verbi sintagmatici. What remains of Cherubini today? Two case studies Since the beginning of the twenty-first century, the phenomenon of dialect resurgence has manifested in Italy through the emergence of dialects in Computer Mediated Communication, especially, on bottom-up created Web sites, like the free, multilingual, online encyclopedia Wikipedia. In this article, we will examine the legacy of Cherubini and his Milanese-Italian dictionary on the regional Lombard version of Wikipedia. We will review the articles both in terms of spelling, comparing the choices of Milanese lexicographer with those most utilized currently online, and from a morpho-syntactic point of view, discussing the presence and the productivity of some phrasal verbs.

  18. Micotossine: prevenire è molto, molto meglio che curare

    Directory of Open Access Journals (Sweden)

    Giuseppe Firrao

    2011-09-01

    Full Text Available Food contamination with fungal secondary metabolites has been a major limit for population wellness and development in the past. Although today social protection against this plague has been established in most countries, there are still many areas in the world where mycotoxin contamination causes illness and even death, due to the lack of healthy conditions for the storage of commodities. Information and knowledge are the main weapons available to contrast the danger of food contamination by mycotoxins. In several instances, information about the severity of the issue alone would have been effective in preventing cases of acute intoxications. Prevention is the winning strategy not only at the level of the end consumer, but also as far as the production is concerned. Thanks to the advances in the understanding of fungal epidemiology and mycotoxin synthesis, strategies for the prevention or at least for the limitation of mycotoxin contaminations have been developed in recent years. As far as cereal production in Italy is concerned, proper storage conditions are now widely adopted, and protocols for good practice in cultivation are being followed by an increasing number of producers. In addition, rapid methods for the early detection of contaminants and quality assessment have been developed and, when introduced in the routine field operation, may lead to substantial improvements of product quality.

    DEFF Research Database (Denmark)

    Bansler, Jørgen P.; Havn, Erling C.

    2003-01-01

    This study analyzes how a group of ‘mediators’ in a large, multinational company adapted a computer-mediated communication technology (a ‘virtual workspace’) to the organizational context (and vice versa) by modifying features of the technology, providing ongoing support for users, and promoting...... of technology-use mediation is more complex and indeterminate than earlier literature suggests. In particular, we want to draw attention to the fact that advanced computer-mediated communication technologies are equivocal and that technology-use mediation consequently requires ongoing sensemaking (Weick 1995)....... appropriate conventions of use. Our findings corroborate earlier research on technology-use mediation, which suggests that such mediators can exert considerable influence on how a particular technology will be established and used in an organization. However, this study also indicates that the process...

  11. Technology and Global Change

    Science.gov (United States)

    Grübler, Arnulf

    2003-10-01

    Technology and Global Change describes how technology has shaped society and the environment over the last 200 years. Technology has led us from the farm to the factory to the internet, and its impacts are now global. Technology has eliminated many problems, but has added many others (ranging from urban smog to the ozone hole to global warming). This book is the first to give a comprehensive description of the causes and impacts of technological change and how they relate to global environmental change. Written for specialists and nonspecialists alike, it will be useful for researchers and professors, as a textbook for graduate students, for people engaged in long-term policy planning in industry (strategic planning departments) and government (R & D and technology ministries, environment ministries), for environmental activists (NGOs), and for the wider public interested in history, technology, or environmental issues.

  13. Technologies as incarnated action

    DEFF Research Database (Denmark)

    Schraube, Ernst

    Contemporary conceptualizations of technology go beyond the traditional interpretation of created things as simply neutral means to an end. They theorize technologies as objects, which embody regimes of power (the theory of technological politics), or scripts (actor-network theory), or values...... (critical theory of technology), or patriarchal thought structures (feminist theories of technology). As helpful as these theories may be to understand the inner relationship between the technosphere and human life, the way in which the life of the individuals in the world of things is imagined remains...... vague and imprecise. In this paper I will argue for a social theory of technology, which includes the subjective and intersubjective implications of technological artifacts. I will show how acting has shifted from the province of human subjects to the sphere of work and products. The created things now...

    Technology empowerment” means that innovation is increasingly accessible to ordinary people of limited means. As powerful technologies become more affordable and accessible, and as people are increasingly connected around the world, ordinary people are empowered to participate in the process of innovation and share the fruits of collaborative innovation. This annotated briefing describes technology empowerment and focuses on how empowerment may create challenges to U.S. national security. U.S. defense research as a share of global innovation has dwindled in recent years. With technology empowerment, the role of U.S. defense research is likely to shrink even further while technology empowerment will continue to increase the speed of innovation. To avoid falling too far behind potential technology threats to U.S. national security, U.S. national security institutions will need to adopt many of the tools of technology empowerment.

  17. Technology '90

    Energy Technology Data Exchange (ETDEWEB)

    1991-01-01

    The US Department of Energy (DOE) laboratories have a long history of excellence in performing research and development in a number of areas, including the basic sciences, applied-energy technology, and weapons-related technology. Although technology transfer has always been an element of DOE and laboratory activities, it has received increasing emphasis in recent years as US industrial competitiveness has eroded and efforts have increased to better utilize the research and development resources the laboratories provide. This document, Technology '90, is the latest in a series that is intended to communicate some of the many opportunities available for US industry and universities to work with the DOE and its laboratories in the vital activity of improving technology transfer to meet national needs. Technology '90 is divided into three sections: Overview, Technologies, and Laboratories. The Overview section describes the activities and accomplishments of the DOE research and development program offices. The Technologies section provides descriptions of new technologies developed at the DOE laboratories. The Laboratories section presents information on the missions, programs, and facilities of each laboratory, along with a name and telephone number of a technology transfer contact for additional information.

  19. Technology and teen drivers.

    Science.gov (United States)

    Lee, John D

    2007-01-01

    The rapid evolution of computing, communication, and sensor technology is likely to affect young drivers more than others. The distraction potential of infotainment technology stresses the same vulnerabilities that already lead young drivers to crash more frequently than other drivers. Cell phones, text messaging, MP3 players, and other nomadic devices all present a threat because young drivers may lack the spare attentional capacity for vehicle control and the ability to anticipate and manage hazards. Moreover, young drivers are likely to be the first and most aggressive users of new technology. Fortunately, emerging technology can also support safe driving. Electronic stability control, collision avoidance systems, intelligent speed adaptation, and vehicle tracking systems can all help mitigate the threats to young drivers. However, technology alone is unlikely to make young drivers safer. One promising approach to tailoring technology to teen drivers is to extend proven methods for enhancing young driver safety. The success of graduated drivers license programs (GDL) and the impressive safety benefit of supervised driving suggest ways of tailoring technology to the needs of young drivers. To anticipate the effects of technology on teen driving it may be useful to draw an analogy between the effects of passengers and the effects of technology. Technology can act as a teen passenger and undermine safety or it can act as an adult passenger and enhance safety. Rapidly developing technology may have particularly large effects on teen drivers. To maximize the positive effects and minimize the negative effects will require a broad range of industries to work together. Ideally, vehicle manufacturers would work with infotainment providers, insurance companies, and policy makers to craft new technologies so that they accommodate the needs of young drivers. Without such collaboration young drivers will face even greater challenges to their safety as new technologies emerge.

    Several emerging or disruptive technologies can be identified that might, at some point in the future, displace established laboratory medicine technologies and practices. These include increased automation in the form of robots, 3-D printing, technology convergence (e.g., plug-in glucose meters for smart phones), new point-of-care technologies (e.g., contact lenses with sensors, digital and wireless enabled pregnancy tests) and testing locations (e.g., Retail Health Clinics, new at-home testing formats), new types of specimens (e.g., cell free DNA), big biology/data (e.g., million genome projects), and new regulations (e.g., for laboratory developed tests). In addition, there are many emerging technologies (e.g., planar arrays, mass spectrometry) that might find even broader application in the future and therefore also disrupt current practice. One interesting source of disruptive technology may prove to be the Qualcomm Tricorder XPrize, currently in its final stages. PMID:27683538

    Nowadays everywhere we come across electronic devices and now the world has become entirely mobile with so many new electronic equipments. The number of computing and telecommunications devices is increasing and consequently the focus on how to connect them to each other. The usual solution is to connect the device with cables or using infra red light to make file transfer and synchronizations possible but infrared light requires line of sight. To solve these problems a new technology,Wibree radio technology complements other local connectivity technologies, consuming only a fraction of the power compared to other radio technologies, enabling smaller and less costly implementations and being easy to integrate with Bluetooth solutions, Furthermore it can be also used to enable communication between several units such as small radio LANs.This paper focuses on why this technology has got large attention although there are pro's and con's with respect to other technologies.

    1994-12-01

    The role of technology in the cost of health care is a primary issue in current debates concerning national health care reform. The broad scope of studies for understanding technological impacts is known as technology assessment. Technology policy makers can improve their decision making by becoming more aware, and taking greater advantage, of key trends in health care technology assessment (HCTA). HCTA is the systematic evaluation of the properties, impacts, and other attributes of health care technologies, including: technical performance; clinical safety and efficacy/effectiveness; cost-effectiveness and other economic attributes; appropriate circumstances/indications for use; and social, legal, ethical, and political impacts. The main purpose of HCTA is to inform technology-related policy making in health care. Among the important trends in HCTA are: (1) proliferation of HCTA groups in the public and private sectors; (2) higher standards for scientific evidence concerning technologies; (3) methodological development in cost analyses, health-related quality of life measurement, and consolidation of available scientific evidence (e.g., meta-analysis); (4) emphasis on improved data on how well technologies work in routine practice and for traditionally under-represented patient groups; (5) development of priority-setting methods; (6) greater reliance on medical informatics to support and disseminate HCTA findings.

    2004-03-01

    Nanotechnology is a revolutionary engine that will engender enormous changes in a vast majority of today's industries and markets, while potentially creating whole new industries. The impact of nanotechnology is particularly significant in the electronics industry, which is constantly driven by the need for higher performance, increased functionality, smaller size and lower cost. Nanotechnology can influence many of the hundreds of components that are typically assembled to manufacture modern electronic devices. Motorola manufactures electronics for a wide range of industries and communication products. In this presentation, the typical components of a cellular phone are outlined and technology requirements for future products, the customer benefits, and the potential impact of nanotechnology on many of the components are discussed. Technology needs include reliable materials supply, processes for high volume production, experimental and simulation tools, etc. For example, even routine procedures such as failure characterization may require the development of new tools for investigating nano-scale phenomena. Business needs include the development of an effective, high volume supply chain for nano-materials and devices, disruptive product platforms, and visible performance impact on the end consumer. An equally significant long-term industry need is the availability of science and engineering graduates with a multidisciplinary focus and a deep understanding of the fundamentals of nano-technology, that can harness the technology to create revolutionary products.

    The Robotics Technology Development Program (RTDP) is a needs-driven effort. A length series of presentations and discussions at DOE sites considered critical to DOE`s Environmental Restoration and Waste Management (EM) Programs resulted in a clear understanding of needed robotics applications toward resolving definitive problems at the sites. A detailed analysis of the resulting robotics needs assessment revealed several common threads running through the sites: Tank Waste Retrieval (TWR), Contaminant Analysis Automation (CAA), Mixed Waste Operations (MWO), and Decontamination and Dismantlement (D and D). The RTDP Group also realized that some of the technology development in these four areas had common (Cross Cutting-CC) needs, for example, computer control and sensor interface protocols. Further, the OTD approach to the Research, Development, Demonstration, Testing, and Evaluation (RDDT and E) process urged an additional organizational breakdown between short-term (1--3 years) and long-term (3--5 years) efforts (Advanced Technology-AT). These factors lead to the formation of the fifth application area for Crosscutting and Advanced Technology (CC and AT) development. The RTDP is thus organized around these application areas -- TWR, CAA, MWO, D and D, and CC and AT -- with the first four developing short-term applied robotics. An RTDP Five-Year Plan was developed for organizing the Program to meet the needs in these application areas.

    2008-01-01

    Biosensor technology is based on a specific biological recognition element in combination with a transducer for signal processing. Since its inception, biosensors have been expected to play a significant analytical role in medicine, agriculture, food safety, homeland security, environmental and industrial monitoring. However, the commercialization of biosensor technology has significantly lagged behind the research output as reflected by a plethora of publications and patenting activities. The rationale behind the slow and limited technology transfer could be attributed to cost considerations and some key technical barriers. Analytical chemistry has changed considerably, driven by automation, miniaturization, and system integration with high throughput for multiple tasks. Such requirements pose a great challenge in biosensor technology which is often designed to detect one single or a few target analytes. Successful biosensors must be versatile to support interchangeable biorecognition elements, and in addition miniaturization must be feasible to allow automation for parallel sensing with ease of operation at a competitive cost. A significant upfront investment in research and development is a prerequisite in the commercialization of biosensors. The progress in such endeavors is incremental with limited success, thus, the market entry for a new venture is very difficult unless a niche product can be developed with a considerable market volume.

    2014-09-01

    There are significant developments underway in new types of actuators for power plant active components. Many of these make use of digital technology to provide a wide array of benefits in performance of the actuators and in reduced burden to maintain them. These new product offerings have gained considerable acceptance in use in process plants. In addition, they have been used in conventional power generation very successfully. This technology has been proven to deliver the benefits promised and substantiate the claims of improved performance. The nuclear industry has been reluctant to incorporate digital actuator technology into nuclear plant designs due to concerns due to a number of concerns. These could be summarized as cost, regulatory uncertainty, and a certain comfort factor with legacy analog technology. The replacement opportunity for these types of components represents a decision point for whether to invest in more modern technology that would provide superior operational and maintenance benefits. Yet, the application of digital technology has been problematic for the nuclear industry, due to qualification and regulatory issues. With some notable exceptions, the result has been a continuing reluctance to undertake the risks and uncertainties of implementing digital actuator technology when replacement opportunities present themselves. Rather, utilities would typically prefer to accept the performance limitations of the legacy analog actuator technologies to avoid impacts to project costs and schedules. The purpose of this report is to demonstrate that the benefits of digital actuator technology can be significant in terms of plant performance and that it is worthwhile to address the barriers currently holding back the widespread development and use of this technology. It addresses two important objectives in pursuit of the beneficial use of digital actuator technology for nuclear power plants: 1. To demonstrate the benefits of digital actuator
