  6. Che genere di diritto?

    Delia La Rocca

    2014-04-01

    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.

  9. ANALYSES OF WIND STRUCTURE OF TYPHOON FUNG-WONG (2008) AND ITS RELATION TO PRECIPITATION REGION

    2009-01-01

    Using real analysis data of 1°×1° resolution of the National Center for Environmental Prediction/National Center for Atmospheric Research (NCEP/NCAR), the nondivergent wind component and irrotational wind component obtained by the harmonic-cosine(H-C) method, and the wind structure of Typhoon Fung-Wong (coded 0808 in China) in 2008 was analyzed. The results indicated that the irrotational component was advantageous over the total wind in reflecting both the changes in convergent height and the asymmetrical convergence of Fung-Wong. In Fung-Wong, the nondivergent component was larger than the irrotational component, but the latter was much more variable than the former, which was obtained only from the wind partition method. Further analyses on the irrotational component demonstrated that the location of the convergent center at lower levels was almost the same as the divergent center during the development of Fung-Wong, and its convergent level was high in its life cycle, with the most highest up to 400 hPa when it became stronger. After the typhoon landed in the provinces of Taiwan and Fujian, respectively, its convergent center at lower levels was slowly detached from the divergent center at high levels and the convergent height was also depressed from high levels to lower levels. Gradually, this weakened the intensity of Fung-Wong. This kind of weakening was slow and Fung-Wong maintained its circulation for a long time over land because of its very thick convergent height. Analyses on wind partitioning provided one possible explanation to why Fung-Wong stayed for a long time after it landed. Furthermore, the asymmetric vertical ascending motion was induced by the asymmetric convergence at lower levels. In general, when typhoons (such as Fung-Wong) land, the rainfall region coincides with that of the convergence region (indicated by the irrotational component at lower layers). This means that the possible rainfall regions may be diagnosed from the convergent

  12. Fast, global, and entrepreneurial: supply chain management, Hong Kong style. An interview with Victor Fung. Interview by Joan Magretta.

    Science.gov (United States)

    Fung, V

    1998-01-01

    Li & Fung, Hong Kong's largest export trading company, has been an innovator in supply chain management--a topic of increasing importance to many senior executives. In this interview, chairman Victor Fung explains both the philosophy behind supply chain management and the specific practices that Li & Fung has developed to reduce costs and lead times, allowing its customers to buy "closer to the market." Li & Fung has been a pioneer in "dispersed manufacturing." It performs the higher-value-added tasks such as design and quality control in Hong Kong, and outsources the lower-value-added tasks to the best possible locations around the world. The result is something new: a truly global product. To produce a garment, for example, the company might purchase yarn from Korea that will be woven and dyed in Taiwan, then shipped to Thailand for final assembly, where it will be matched with zippers from a Japanese company. For every order, the goal is to customize the value chain to meet the customer's specific needs. To be run effectively, Victor Fung maintains, trading companies have to be small and entrepreneurial. He describes the organizational approaches that keep the company that way despite its growing size and geographic scope: its organization around small, customer-focused units; its incentives and compensation structure; and its use of venture capital as a vehicle for business development. As Asia's economic crisis continues, chairman Fung sees a new model of companies emerging--companies that are, like Li & Fung, narrowly focused and professionally managed.

    Chun Xiao, a famous Tang poetry, written by Meng Haoran, has been translated by some great translators. In translat⁃ing poems, what is important is not only the transferring of the intended meaning of the source language into target language, but keeping its literariness, i.e. the style of the original text. Three English versions are selected to make a comparative study from the perspective of reception aesthetics in terms of lexicon, rhyme and syntax.

  18. 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.

    Based on the inductively coupled plasma mass spectroscopy (ICP-MS) data of concentrations of 7 heavy metals (including Cr, Ni, Cu, Zn, Cd, Pb and As) in suspended particles and surface sediments samples collected at 6 and 1 13-hours-mooring stations, respectively, in Quanzhou Bay 4 days after the landing of typhoon "Fung-wong". The average contents of Cr, Ni, Cu, Zn, As, and Cd are 60.4, 50.3, 26.5, 101.7, 3.36, 40.0 and 0.180 microg/g, respectively, in the surface sediments, and are 1.108-7.408, 0.476-3. 394, 0.809-5.046, 3.190-19.337, 0.087-0.595, 2.621-10.073 microg/L and 4.160-50.828 ng/L, respectively, in different stations in the suspended particles. The contents and distribution patterns of 7 heavy metals during a tidal cycle were significantly changed after typhoon "Fung-wong" by contrasting with that in same stations and tidal time at an ordinary situation. The contents of heavy metals, besides Ni, evidently decreased but the distribution patterns were similar with that in an ordinary condition with relatively large grads after typhoon "Fung-wong" in the surface sediments at station Q4. While in the suspended particles, the contents of heavy metals were evidently increased with the distribution patterns varied obviously and differently due to their geographical position after typhoon "Fung-wong". These impacts of typhoon "Fung-wong" to the contents and distribution patterns of heavy metals could be attribute to the "second contamination" and the increased supply of particles materials from continent during the typhoon process. The results of this study provide a reference to accurate assessing and scientific governing the heavy metals' contamination, and provide a directly support to evaluating the integrated impacts of typhoon process on the contamination of heavy metals in the Quanzhou Bay.

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

    2011-08-01

    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

  4. 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.

  9. Writing Gardens - Gardening Drawings: Fung, Brunier and Garening as a model of Landscape Architectural Practice

    Directory of Open Access Journals (Sweden)

    Julian Raxworthy

    2004-06-01

    Full Text Available Landscape architecture is different from other design discourses, notably architecture, because of its utilisation of' dynamic' construction media such as plant materials, soils and water, compared with the 'static' materials of architecture, colloquially described as bricks and mortar. This dynamism refers to the fact that landscape materials not only change, but get better over time. While this is a material difference, its implications extend to practice, which has been modelled, from architecture, to favour a static mode of representation: the drawing. While the drawing is important for the propositional nature of landscape architecture, it may be valuable to look at other disciplines, allied to landscape architecture, which might be seen as better able to engage with change. In this essay, the garden provides just such an example. In the writings of Stanislaus Fung on the Chinese garden text the Yuan vi, an argument is made about writing being a fundamental act in the endeavour of gardening that may offer a bridge across the 'ontological disparity' that exists between representation and the subject, the landscape. To speak of writing in this context suggests that writing about gardens is actually a type of gardening in itself. This argument is extended in the current essay quickly to see if it is also appropriate to consider drawings in this way. This essay also attempts to legitimate theoretically the real possibility of modifying landscape architectural practices to engage with change, by suggesting what might be learned from gardening. In further research by this author, this argument will be used as the theoretical basis for critiquing gardens in such a way that lessons learnt from garden designers can be valuably incorporated back into the discourse of landscape architecture.

    To solve the trace metal pollution of a Pd/Zn mine in Hunan province, a greenhouse pot experiment was conducted to investigate the effect of two arbuscular mycorrhizal fungi, Glomus mosseae (Gm) and Glomus intraradices (Gi), on the growth, heavy metal uptake and accumulation of Zenia insignis Chun, the pioneer plant there. The results showed that symbiotic associations were successfully established between the two isolates and Z. insignis in heavy metal contaminated soil. AM fungi improved P absorption, biomass and changed heavy metal uptake and distribution of Z. insignis. AM fungi-inoculated plants had significantly lower Fe, Cu, Zn, Pd concentrations and higher Fe, Cu, Zn, Pd accumulation than non-inoculated plants. However, Gm and Gi showed different mycorrhizal effects on the distribution of heavy metal in hosts, depending on the species of heavy metal. Gi-inoculated Z. insignis showed significantly lower TF values of Fe, Zn, Pd than Gm and non-inoculated plants, while both strains had no effect on TF value of Cu, which indicated that Gi enhanced trace metal accumulation in root system, playing a filtering/sequestering role in the presence of trace metals. The overall results demonstrated that AM fungi had positive effect on Z. insignis in enhancing the ability to adapt the heavy metal contaminated soil and played potential role in the revegetation of heavy metal contaminated soil. But in practical application, the combination of AM, hosts and heavy metal should be considered.

    AIM: To study the mechanism of Je-Chun-Jun (JCJ)-inducing the apoptosis of the human cervical carcinoma,HeLa cells. METHODS: The cell viability was assessed using MTT assay. The optical density was measured at 570 nm. The caspase activity was measured using 50 mmol/L of fluorogenic substrate, AC-DEVD-AMC (caspase3), AC-VEID-AMC (caspase-8) or AC-LEHD-AFC (caspase-9). To confirm the expression of proteins, Western blotting was performed. To detect the characteristic of apoptosis chromatin condensation, HeLa cells were stained with Hoechst 33258 in the presence of JCJ. For the cell cycle analysis, HeLa cells were incubated with Propidium iodide (PI) solution. Fluorescence intensity of cell cycle was measured using flow cytometry system. RESULTS:The loss of viability occurred following the exposure of 10 g/L JCJ. Cells treated with 10 g/L JCJ for 3 d exhibited the apoptotic morphology (brightly blue-fluorescent condensed nuclei by Hoechst 33258-staining) and the reduction of cell volume. Cells incubated with JCJ for 48 h were arrested at the G1 phase of cell cycle and their G1 checkpoint related gene products such as cyclin D1 were transiently decreased. We showed that JCJ induced the p38 MAPK activation in HeLa cells. The p38 MAPK inhibitor, SB203580 protected Hela cells from the JCJ-induced death as well as intervened the JCJ-induced accumulation of cells at the G1 phase. In contrast, MEK1 (-ERK upstream) inhibitor, PD98059 had no effect on HeLa cells. CONCLUSION: JCJ induced cell cycle arrest and apoptosis of HeLa cells through p38 MAPK pathway.

    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.

    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. Per queste ragioni, non basta essere “sensibili” all’argomento ma bisogna conoscerlo, bisogna essere preparati, studiare, ed è fondamentale che la formazione valga per giudici, forze dell’ordine, avvocati e avvocate, psicologi e psicologhe, assistenti sociali, ma anche per i giornalisti e le giornaliste che si vogliano occupare di questi temi. La responsabilità mediatica è particolarmente grave, perché quando l’informazione si consuma sulla pelle di esseri umani – come donne e bambine che rischiano la loro stessa incolumità – ognuno di dovrebbe fare un esame di coscienza chiedendosi: quali potrebbero essere le conseguenze se sbaglio o se sono superficiale? Risolvere il problema culturale anche attraverso una corretta informazione, è il nodo da sciogliere.

An outstanding example is Cheng' s interpretation of Chun Qiu, which is distinctive, such as coherent comprehension of the three Zhuans, rational interpretation of the classics, annotating Chun Qiu on the basis of Si Shu, emphasizing Chun Qiu literary style and interpretati through Li Xue. These all provide paradigms for succeeding annotations of Chun Qiu, i.e. Li Xue reform of Ch Qiu. Undoubtedly, Cheng Yi' s contribution to the study of Chun Qiu of Song Dynasty is significant.

    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.

    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.

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.

    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.

    An in vitro system was used for ectomycorrhizal synthesis of Cenococcum geophilum Fr. with Cathaya argyrophylla Chun et Kuang, an endangered species. Calli initiated from stem segments and adventitious roots differentiated from young seedlings were removed and cocultured with Cenococcum geophilum on a modified Murashige-Skoog medium. Fungal hyphae were visible within intercellular spaces of the callus 4 weeks after inoculation, but definite and well-developed Hartig net structures did not form in the calli 8 weeks after inoculation. The typical ectomycorrhizal structures (i.e. hyphal mantle and intracortical Hartig net) were observed in root segments 8 weeks after inoculation. This is the first report of aseptic ectomycorrhizal-like formation/infection between root organ/callus of Cathaya argyrophylla and the ectomycorrhizal fungus Cenococcum geophilum. This culture system is useful for further investigation of mycorrhizal synthesis in Cathaya trees.

In regards to the more and more practical education of medical students there is an increasing need for the implementation of OSCEs. To facilitate this implementation we would like to give a review of literature and to present our 12 station OSCE at the Medical Hospital of the University of Heidelberg. Methods: During winter term 2004 / 2005 143 medical students in thir 3rd year of training participated the OSCE. For the conception of the assessment a blueprint was used. Standard setting was carried out with a modified Angoff method, students performance was assessed by experts using self-developed checklists. Results: The OSCE at the Medical Hospital of the University of Heidelberg showed a reliability of 0,748. According to the results of the standard setting procedure 142 students (99,3% passed the exam. Taking the OSCE on the first, second or third day of assessment did not have impact on students' performance. Discussion: The OSCE at the Medical Hospital of the University of Heidelberg proves to be a reliable and fair assessment tool. Even the OSCE represents an assessment tool that needs resources and time it is well accepted in students and raters if it is planned and organised carefully.

  5. 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.

    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

    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.

    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.

    Quercus tiaoloshanica Chun et Ko, which has a narrow range of distribution, is one of the important endemic species of the tropical montane rain forest on Hainan Island, southern China. Long-term logging and habitat destruction have resulted in population decline and distribution retreat of Q. tiaoloshanica. To determine the impact of logging on the genetic diversity of Q. tiaoloshanica, the authors investigated the genetic structures using amplified fragment length polymorphism markers in four regenerated stands after logging and in one unlogged stand. Compared with the unlogged stand, the effective number of alleles per locus dropped by 1.0% in selective logging stands and by 2.0% in clear logging stands,corresponding to reductions of 3.8% and 5.2%, respectively, in mean Nei's gene diversity and 2.9% and 3.5%, respectively, in mean Shannon diversity index. No substantial genetic erosion was detected in any of the regenerated stands owing to the high tree density and high heterogeneity of the Q. tiaoloshanica stands investigated. Meanwhile, there was no natural regeneration of the species observed in a Dacrydium pierrei Hickel plantation 700 m away from the regenerated stands, suggesting the limited ability of seed dispersal of Q. tiaoloshanica. Clear logging should be undertaken cautiously because the total number of plant species dropped by 15.2% in the clear-logged stands compared with the unlogged stand. To conserve the genetic diversity of this species, as well as the plant biodiversity of tropical forests, the habitats of Q. tiaoloshanica should be protected against exploitation in terms of agricultural or other forms of land use, and some mature trees should be preserved as seed sources to maintain an adequate regeneration base for this species in the management of logging.

    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.

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

    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.

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

    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.

  2. 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

    Laboratory work is the cornerstone of experimental planetary geochemistry, mineralogy, and petrology, but much is 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 H2O vapor pressure), but observations on-planet provide an 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 tested 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 XRD detection of abundant gypsum and a chance to observe gypsum stability. Laboratory work suggests gypsum is 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, although LIBS by ChemCam indicates that bassanite predominates in Ca-sulfate veins. Laboratory experiments show that on dehydration gypsum does not become X-ray amorphous but rather transforms to water-deficient bassanite. 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

A partire dalla definizione del romanzo come racconto di finzione, viene sviluppata  una posizione di cognitivismo radicale, per la quale il romanzo (a produce conoscenza modale; (b giustifica questa conoscenza in base al principio della verosimiglianza; (c favorisce l’apprendimento per esperienza in virtù dell’esemplificazione immaginativa. Le tesi proposte vengono corroborate in riferimento ai recenti dati sperimentali ottenuti dalle scienze cognitive, in particolare dalla psicologia cognitiva, sull’immaginazione, la finzione, la simulazione.

    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.

    2016-02-01

    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

  10. 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

    Energy Technology Data Exchange (ETDEWEB)

    Lee, Seok-Yong

    2003-04-10

    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.

    2011-04-01

    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 relationship between the hypertension and the aging process of hearing organ was in-vestigated. Twenty Wistar 3-month old rats and 20 Wistar 12-month old rats, 20 spontaneously hy-pertensive rat stroke-prone (SHRSP) 3-month old rats and 20 SHRSP 12-month old rats free ofmiddle ear infections as observed under otomicroscopy, with normal tympanic membrane and auriclereflex, were selected to be divided into two experimental groups and two control groups respective-ly. The tail artery blood pressure was measured non-invasively. The threshold of auditory brain-stem response (ABR) was measured by SpiritTM evoked potential meter. The LDH and ChE stai-ning in the inner ear was performed and the optical density was analyzed by the HPIAS analysis sys-tem. The results showed that there was no difference in the ABR thresholds, the activities of LDHand ChE between Wistar 3-month old group and SHRSP 3-month old group (P>0. 05). 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.

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

    Blake, D. F.; CheMin Science Team

    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

    The TV Series Sha Chun is a typical show of traditional Chinese family ethics life. Familism has a strong family unity and emphasis on family heir reproduction, the tress of the Ancestor command, focusing on public property, the family characteristics of the overall honors. However, in contemporary China, conflicts between the family interests and the rights of the individual, family private morali- ty and public morality , that emphasis on men and equal rights of every member,make the old ethics face the danger of disorganization. The new family ethic should adhere to the principle of unity of emotion and justice, respect for freedom and individuality of each member, the principle of great importance to the cultivation of a sense of social responsibility. This shift is the contemporary fate of traditional Chinese family ethics.%电视连续剧《傻春》是中国典型的传统主义家庭伦理生活的当代写照。家庭主义具有强烈的家庭一体感、重视家族嗣繁衍、强调属遵祖训、注重财物公有、重视家庭整体荣誉的特点。然而在当代中国,家庭利益与个人权利的矛盾、家庭私德与社会公德的矛盾、重男思想与权利平等的矛盾,使这种伦理观在当代面临解组的危险。新型家庭伦理观应坚持亲情与正义相统一原则、尊重每个成员的自由与个性、重视社会责任感的培养等原则,这种伦理转向是传统家庭主义的当代宿命。

    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 Abstract - IT Questo lavoro nasce da una ricerca di campo sulle frazze, termine dialettale che indica le farse di Carnevale che si rappresentavano fino a cinquant’anni fa in molti paesi calabresi, tra cui il mio, Crucoli, in provincia di Crotone. Lo scopo di questo lavoro non è fare un resoconto esaustivo di tutto ciò che accadeva a Crucoli durante la celebrazione del Carnevale, impresa assai difficile dal momento che non ci sono documenti scritti e quindi bisogna affidarsi ai racconti orali delle persone intervistate, spesso non fedeli alla realtà, perché modificati dal tempo e dalla memoria. L’approccio con cui ho intrapreso questa ricerca è sicuramente legato all’aspetto teatrale e performativo dell’evento, senza trascurarne la rilevanza antropologica. Il materiale raccolto è frutto di interviste e colloqui con la gente del posto unito ad un grande lavoro di ricerca bibliografica di autori che avevano trattato di questo argomento in relazione ai loro paesi di origine.Lo scopo è quello di delineare l’organizzazione e lo svolgimento delle frazze, cercando di ricostruire la sua durata e le ripercussioni sulla comunità, nonché dimostrare ancora una volta come il teatro, messo a disposizione di alcuni eventi, diventi un mezzo forte di liberazione e di contestazione.

    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.

    Alessandra Diazzi

    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.

    2011-07-01

    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.

  12. A predictive computational model of the kinetic mechanism of stimulus-induced transducer methylation and feedback regulation through CheY in archaeal phototaxis and chemotaxis

    2010-03-01

    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.

  2. Structural studies of conformational changes of proteins upon phosphorylation: Structures of activated CheY, CheY-N16-FliM complex, and AAA + 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, 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.

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

    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

    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. Il campionamento dei macroinvertebrati e` stato effettuato utilizzando due diversi metodi di raccolta: i substrati artificiali e il retino immanicato standard. Gli organismi sono stati classificati in unita` sistematiche, e si e` analizzata la loro distribuzione lungo il corso d`acqua. Inoltre sono stati calcolati i valori degli indici biotici I.B.E. (Indice Biotico Esteso) utilizzando i dati ottenuti con le due metodologie di campionamento. L`uso di substrati artificiali in ogni stazione di campionamento e` stato utile anche per stabilire il tipo di colonizzazione, l`abbondanza e le biomasse degli individui appartenenti ai vari gruppi trofici.

    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.

    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.

    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 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.

    Aqueous extract of the leaves of Dendropanax chevalieri (DC), administrated orally, showed prominent protective effect against arrhythmias induced by iv aconitine CaCl2 (120mg/kg) in mice and BaCl2 (4mg/kg) in rats. In anesthetized rabbits, the duration of arrhythmia elicited by ivAdr 75 micrograms/kg was markedly shortened by iv DC 0.4g/kg. It might also obviously delay the onset of arrhythmias and cardiac electricity disappearance evoked by ouabain perfusing consistently into isolated guinea-pig hearts.

    Genetic diversity level of Cathaya argyrophylla was confirmed by random amplified polymorphic DNA (RAPD) markers. Seventy five samples (individuals), collected from Hunan and Sichuan provinces of China were used in the study. 21 10-mer oligonucleotide primers detected 106 sites, and 34 (32% ) of them were polymor-phic. The level of genetic variation in C. argyrophylla was lower than those of other conifers, and was considered to be associated with the complexity of habitats. The percentages of polymorphic sites (PPS) in the Hunan and Sichuan pop-ulations were 18% and 25% respectively. 7.99% of genetic variation existed between the two populations; this value was higher than the mean value (6.8%) among populations in conifers displayed by allozyme. Some subpopulations of C. argyrophylla were greatly differentiated because of site mutation and genetic drift. The highest value of genetic dif-ference between subpopulations amounted to 16. 23% . In addition, a concept of diversity coefficient(DC), a value us

    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

Il analyse pour cela les articles issus de deux numéros de revues et un ouvrage collectif récents. Il apparaît que la grande majorité des scénarios pédagogiques s'y inscrit dans la perspective actionnelle... du moins d'après la déclaration des auteurs, car leur définition de ce qu'est une tâche ne correspond pas toujours à celle du CECR. Pour le public visé, étudiants ou professionnels, on propose le plus souvent des mono-tâches, mais également des projets, ou encore des simulations avec un enchaînement de plusieurs tâches. Elles s'inscrivent généralement dans la (future réalité sociale des apprenants, mais certaines laissent également la place à des thèmes artistiques ou (interculturels.

    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.

    Accumulation of methane as gas hydrate under the sea floor has been considered a major trap for both thermal and biogenic gas in marine environment. Aided by rapid AOM process near the sea floor, fraction of methane escaping the sea floor has been considered at minuscule. However, most studies focused mainly on deepwater gas hydrate systems where gas hydrate remain relatively stable. We have studied methane seeps on the active margin offshore Taiwan, where rapid tectonic activities occur. Our intention is to evaluate the scale and condition of gas seeps in the tectonic active region. Towcam, coring, heat probe, chirp, multibeam bathymetric mapping and echo sounding were conducted at the study areas. Our results showed that gas is violently venting at the active margin, not only through sediments, but also through overlying sea water, directly into the atmosphere. Similar ventings, but, not in this scale, have also been identified previously in the nearby region. High concentrations of methane as well as traces of propane were found in sediments and in waters with flares. In conjunction, abundant chemosynthetic community, life mussel, clams, tube worms, bacterial mats together with high concentrations of dissolve sulfide, large authigenic carbonate buildups were also found. Our results indicate that methane could be another major green house gas in the shallow water active margin region.

    In 2003, Margaret Chan Fung Fu-chun, former Director of Health of the Hong Kong government, was criticized for her unsatisfactory performance in handling the SARS outbreak. But three years later, she was celebrated for her success in the contest for the WHO director-generalship. How was she transformed from an incompetent official into an "honor winner" for China and Hong Kong? In what context was this made possible? How was the collective memory about Chan recalled and reconstructed? This article tackles these questions by reviewing relevant reportage and commentary in major local (Hong Kong), national (China), and international media. It maps the political context of the media discourse and explores the construction of a collective past to foster national cohesion in postcolonial Hong Kong.

    Directory of Open Access Journals (Sweden)

    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.

    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.

  9. Su che cos’è l’economia politica

    Directory of Open Access Journals (Sweden)

    Roberto Cellini

    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

  18. 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.

  2. 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.

    This paper builds on a recently developed immersogeometric fluid-structure interaction (FSI) methodology for bioprosthetic heart valve (BHV) modeling and simulation. It enhances the proposed framework in the areas of geometry design and constitutive modeling. With these enhancements, BHV FSI simulations may be performed with greater levels of automation, robustness and physical realism. In addition, the paper presents a comparison between FSI analysis and standalone structural dynamics simulation driven by prescribed transvalvular pressure, the latter being a more common modeling choice for this class of problems. The FSI computation achieved better physiological realism in predicting the valve leaflet deformation than its standalone structural dynamics counterpart.

    Full Text Available Absent from most public debates on Taiwan’s embrace of neoliberal capitalism are the potential consequences of economic liberalization for Taiwan’s indigenous peoples. Deregulating markets and unfettering capital and resources are tied inextricably with cross-Strait politics. With a deep-seated apprehension of China still felt in many corners of the Taiwanese society, these issues are often framed with particular emphasis on the “China Factor”, overshadowing other relevant economic and societal considerations and thereby narrowing the scope of debate over government policies. Nevertheless, the potential influx of foreign capital investment, long- and short-term migrant labor and international visitors may have profound effects on Taiwan’s most vulnerable citizens, including the indigenous peoples. This paper will report the results of field research conducted among the Paiwan ethnic group, assessing actual and potential future changes affecting their individual families and communities. Preliminary assessment indicates that official policies liberalizing visitation and trade between China and Taiwan have already affected the Paiwan communities. Whether these changes become handicaps or opportunities depends on realistic evaluation, strategic planning, education, implementation, and periodic re-evaluation. This paper will contribute to the larger discussion of possible responses to the effects of inter-regional migration and transformations on minority societies by providing an assessment of current and potential conditions among the Paiwan of Taiwan.

    Sociology of knowledge was introdrced to China by some professors and strdents of sociology at Yanching University in the 1930s.Its introdrction was seen as a tool for constrrcting a social scientific framework of knowledge in Chinese strdies,which world cover commrnity strdies of Han Chinese,ethnic strdies and overseas strdies.The three parts shared a character in common:the approach of comparative strdies of sociology of knowledge.Under this approach,the sociologists of “Yanching School”focrsed on the ethos of commrnity or nation and how ethos were diversely expressed throrgh different kinds of relationships between ideas and institrtions. It is throrgh the comparative strdy of social ethos that the plrralistic strrctrre of Chinese civilization corld be examined.To reveal this method specifically,this paper offers a comparative analysis of three key figrres ’ works from “Yanching School”:Wr Wenzao,Fei Xiaotong and Li An-che.These three sociologists developed their own rniqre path of empirical strdies of sociology of knowledge. Wr was a follower of Karl Mannheim and believed that society constrains knowledge and intelligentsia,leading to a type of statism that trrsts state to frnction as a reformer above society throrgh action.Fei seemed to waver between Mannheim and Max Weber rntil the 1950s.In his late years,Fei began paying attention to New Confrcianism and srggested that social science shorld borrow from hermenertics and strdy the qrestion of “Mind”.At this time,Fei actrally went back to Zhang Dongsrn for the same inqriries.Li was originally the most faithfrl follower of Mannheim of the three,brt he soon trrned to Weber rnder the inflrence of Zhang Dongsrn.He was interested in how the entire system of knowledge was being interpreted and internalized at different levels of society,whether they were elite intelligentsia,the dominant class or common people.All three sociologists cared for the same qrestion:did Chinese civilization achieve its

    2011-01-01

    In 1776, the Sienese botanist Biagio Bartalini (1750-1822) published a catalogue of wild plants growing around Siena, adding an appendix on fossils found in the same area, that is the first monograph on Sienese fossils and one of the first works of its kind in Italy. This paper provides tentative identifications of the species and an analysis of the value and meaning of Bartalini's work. The catalogue reports 72 species, each denoted by a list of names applied to analogous living taxa. Identification of single entities is extremely problematical because it can only be attempted through analysis of the literature, since the original material cannot be traced. The most interesting report is the first record of a Euro-Mediterranean Pliocene species of Sthenorytis (Gastropoda, Epitoniidae). Though important, the catalogue is incomplete, with oversights and mistakes, suggesting little familiarity with the subject. Shortcomings include some inconsistencies in the species sequence, the report of giant clams and the absence of molluscs ubiquitous in the Sienese Pliocene and sharks. Nor is it true that it is the first Italian palaeontological work in which binomial nomenclature was used, as sometimes claimed.

    Here we describe dental remains from a Neanderthal fossil assemblage from Moula-Guercy, France. Our report demonstrates that the Moula-Guercy hominid remains contribute important morphological, developmental, and behavioral data to understanding Neanderthal evolutionary history. We include gross comparative morphological descriptions and enamel surface microstructure and microwear data. These teeth reveal numerous characteristics that are diagnostic of Neanderthals and provide no evidence for the presence of any other hominid taxa. Enamel growth increment data from the Moula-Guercy specimens yield evidence of a Neanderthal pattern of development, although at the lower end of the range of variation. The presence of a significant number of linear enamel hypoplasias indicates that these individuals were stressed during childhood. Molar microwear data suggest that these Neanderthals did not differ significantly from modern humans in terms of the fracture properties of the food they were consuming. The incisor microwear and macro striations provide evidence that these individuals may have been using their anterior teeth as tools, similar to the practices of several modern human populations such as the Inuit, Ipiutak, and Australian Aboriginals, and reminiscent of evidence from other Neanderthals from Krapina, Croatia, as well as the 600,000 year old hominids from Sima de los Huesos, Spain.

    Full Text Available This article explores the use of a foreign language in Ottoman women’s autobiographical writing that first appeared between the end of the 19th century and the beginning of the 20th century. By analyzing the texts of these authors writing about the self outside of their “mother tongue”, this article addresses the issue of language – in this case English – as a negotiated space for one’s own multiple identities, both with local and Western audiences. In particular, it examines to what extent the choice, however conscious, of using a foreign language engenders an identity break, a separation of the author from the world in which her memories were originally produced. Furthermore, this article seeks to determine the traumas that could motivate or arise from this choice.

    Full Text Available The analysis of the investigations related to evaluations on the process of reduced ore cooling in rotating horizontal cylinders on an industrial scale indicated that there are only water temperature measurements on one end of pit and showed no experiments where the variables of water and ore flowrates were evaluated nor the relation with the temperature of the ore at the cooler outlet. Based on this precedent, six thermocouples were installed to calculate the cooling water temperature in three locations on both sides of the pit connected to the data input system in place in the enterprise. The design of the experiment was developed from analyzing a population of data from a 6/month period. The results showed that the variable of greater impact on the ore temperature at the cot oler outlet is the water flowrate. For lower water flowrates (15m3/h heat transfer by water evaporation to the air is predominant and for higher water flowrates (25m3/h heat transfer by convection is predominant. Also, it was possible to know that the cooler heat output reaches the highest values (86% with the lowest ore and water flowrates (15m3/h and 29t/h, respectively.

    Gastropod molluscs are one of the most important components of mangrove ecosystem. Mangroves in Central Vietnam have a rather limited distribution due to peculiarities of the coastline morphology and presently their fauna remains understudied. Extensive surveys were conducted in both natural vegetation and artificial mangrove plantations in several localities in Nha Trang Bay from 2005 to 2015. In total 65 species of gastropod molluscs were found alive, 17 of which can be considered as predominantly mangrove-associated. An illustrated guide is provided, with short synonymies and data on ecology and distribution. The recorded molluscan diversity is compared with published data on mangrove gastropods in different regions of the Indo-Pacific. Total species number and the proportion of mangrove-associated species are similar to studied faunas in Hong Kong, Malaysia and Thailand, but the diversity is much lower than that of the mangal fauna of the Philippines.

    Five crude extracts were made from leaves and stems of Jasminum subtriplinerve Blume (Oleaceae) and investigated for antimicrobial, antioxidant and cytotoxic activities. The extractions were done with petroleum ether, ethyl acetate, ethanol, methanol or water. All extracts exhibited anti-bacterial activity except the water fraction. On the other hand, all extracts exhibit antioxidant activity except the petroleum ether fraction using the DPPH radical scavenging assay. Only the petroleum ether fraction showed a cytotoxicity activity against tested cell-lines, Hep-G2 and RD with IC(50) values of 19.2 and 20 microg mL(-1), respectively. From the petroleum ether and ethyl acetate extracts, two triterpenes namely 3beta-acetyl-oleanolic acid and lup-20-en-3beta-ol and a sterol, stigmast-5-en-3beta-ol were isolated. The structure of those compounds were elucidated by spectrometric methods IR, MS, 1D-NMR, 2D-NMR and simulated ACD/NMR spectra. The data presented here indicate that J. subtriplinerve do contain compounds with interesting biological activity.

El corpus expone itinerarios culturales cruciales de los años 60-70, en las discusiones que los relatos plantean como sus núcleos temáticos -estética y/o política, alta cultura o cultura popular, inquietud intelectual vs. compromiso revolucionario-, pero además en las diversas formas que el discurso adopta para contar el viaje -reportaje, diario, ensayo, crónica, ficción literaria-. Así, desde Ernesto Guevara a Enrique Raab -pasando por Jorge Masetti, Rodolfo Walsh, Ezequiel Martínez Estrada y Leopoldo Marechal-, el trabajo recorre cartografías viajeras dela Cuba revolucionaria cuya configuración resulta inseparable de los lugares sociales transitados por quienes toman la palabra: esa cuestión, en el campo cultural politizado de los años 60-70, representaba un eje central del debate.

Kann man sie speichern? Wird sie bald eine Rolle im Alltag spielen? Und warum verdanken wir unsere Existenz – und die unseres Universums – einem winzigen Unterschied zwischen Materie und Antimaterie? Rolf Landua, einer der weltweit führenden Experten auf diesem Gebiet, beantwortet in seinem neuen Buch anschaulich diese und andere Fragen.

    Full Text Available At the very central point of the first episode in the Matrix Trilogy (1999-2003 is the cornerstone of the film’s narrative: the scene of Cypher’s betrayal, also known as the restaurant scene, which immediately received special attention from scholars. As regards the tone of interpretations, so far it has been almost a competition to issue the more sophisticated and persuasive verdict of guilty, and all of them agree, even the not incriminating ones, in believing Cypher as an incurable selfish hedonist. Their hermeneutical common limits are basically three: a they treat the Cypher case only by analyzing the verbal level, that is the script, and then by abstracting from the fact that it’s a story in a filmic text; b they isolate and crystallize the character in Chapter 19 of Matrix (the dialogue between Neo and Cypher and the restaurant scene, as though he appeared only in this specific context and not already at the beginning of the film; c they apply from above and extrinsically the theoretical formulas of some philosophers (no matter if Kant, Mill, Nietzsche, Nozick etc. dealt with as if taken from a handbook. The suggested interpretation sounds like a completely different register. We do not refer to any philosopher, instead we refer to the verse from a book of VT, Judges 16.30, in which a very similar impulse to the one moving Cypher is found. And of this character, who has an extraordinary tragic depth, the simulational and cryptogramatic structural shape is shown.

  17. Middle Pleistocene ecology and Neanderthal subsistence: insights from stable isotope analyses in Payre (Ardèche, southeastern France).

    The Middle Palaeolithic site of Payre in southeastern France yields abundant archaeological material associated with fossil hominid remains. With its long sequence of Middle Pleistocene deposits, Payre is a key site to study the Middle Palaeolithic chronology of this region. This study is the first to investigate carbon and oxygen isotope contents of Neanderthal tooth enamel bioapatite, together with a wide range of herbivorous and carnivorous species. The aim is to contribute to the understanding of hunting behaviour, resource partitioning, diet and habitat use of animals and Neanderthals through a palaeoecological reconstruction. Local topography had a visible influence on carbon and oxygen stable isotope values recorded in herbivore tooth enamel. This was used to investigate possible habitats of herbivores. The different herbivorous species do not show large variations of their carbon and oxygen isotope values through time, indicating niche conservatism from OIS 8-7 to OIS 6-5, i.e., independently of palaeoclimatic and palaeoenvironmental variations. Based on these new observations, we conclude that Neanderthals employed a stable subsistence strategy over time, using a variety of local resources, with resource partitioning visible between humans and carnivores, especially wolves. A comparison of the results of stable isotopic investigation with the results of tooth wear analyses previously conducted on the same teeth allowed us to demonstrate that grazing and browsing do not bind animals to a specific habitat in a C3 environment as reflected in the isotopic values.

    2017-06-01

    Full Text Available In order to identify the paternity of Cinquecento engravings Vasari did not have sufficient critical tools in the absence of monograms or inscriptions. It was the “sign” (segno, the only element that allowed him to recognize the hand of an engraver. However, when those “signs” did not help him sufficiently, Vasari also sometimes suggested attributions based on the authorship of the inventions. In some of these cases he succeeded, probably only thanks to his eye and his knowledge of style, to identify the author of the inventions but, in other cases, he was misled by what his knowledge, without being able to judge those prints only by their style. The article intends to analyse this dynamic and to understand the operations at the origins of attribution’s mistakes.

    2015-07-01

    Full Text Available Italo Calvino, the eye that writesThe dynamics of Calvino’s authorial image in literary criticismItalo Calvino has been quickly canonized in Italian literary criticism. Already during the lifetime of the Ligurian author a sort of ‘essential Calvino’ has affirmed itself in criticism. This essential Calvino is constituted by a conglomeration of images, ideas and keywords that define the author, at least according to critical consensus. This ‘essential Calvino’ has, however, not only been formed by critics, but certainly too by Calvino himself, who has contributed greatly to his own authorial image. By adopting various roles, from writer to essayist, editor, journalist and director of book series, Calvino managed to influence the reception of his works with a multifaceted authority. The aim of this article is to investigate how Calvino has become ‘Calvino’, the author whose critical image seems to have clear outlines. The idea of Calvino as a precise and geometrical observer, light but thoughtful, multiple but coherent, has been elaborated in a dialogue between the various ‘Calvini’ and literary critics. These images of Calvino do not only have direct and visible repercussions, but also more indirect and invisible consequences. In the case of Calvino, his metaphorical (but also biographical marginality coincides with his place at the margins of volumes (on covers and in introductions that he acquired early on in his career and that continues until this day. By interlacing a paratextual and discourse analysis with the institutional and cultural context of Calvino’s career, one can hope to gather a better insight into Calvino’s critical reception and the process of critical circulation and reception in general.

    Full Text Available CONTEXT: The number of elderly is constantly increasing in the western world and many of this people spend the last years of their life in a nursing home with physical and/or mental disabilities. OBJECTIVE: To estimate the Health Service resource and direct costs for Community Residential Care (CRC disabled elderly people. METHODS: A retrospective observational study was conducted between January 2002 and December 2002 among all CRC (23 CRC and 1665 disabled residential elderly population REP of the Local Health Authority n° 9 of Treviso. For each CRC data regarding patients, hospitalisation, clinical analysis, general practitioner and hospital medical doctor assistance, drug utilisation were collected and analysed. RESULTS: Males were 27% and female 73% with an average age 78 and 86 years old respectively. Frequency of hospitalisation, clinical analysis and drug utilisation vary widely between the CRC and an inverse correlation is observed between cost of hospitalisation and drug plus clinical analysis. The first causes of hospitalisation are pneumonia 7.2% and cardiovascular disease 4.9% both considered preventable cause of hospitalisation. Regarding the drug consumption analysis enalapril, furosemide, omeprazole are the most used molecules with a consumption of 308, 185, 166 DDD/1000 REP/die; systemic antibiotics are the more expensive drugs with a cost of 0.3 euro/REP/die. Unexpected laxatives consumption is lower than data from literature with a 17% of the total REP exposed. Finally average annually cost for a REP in CRC is 16,445 euros and beside the direct sponsor of local health authority to the CRC hospitalisations cost are the most important (899 euros while drugs, medical assistance and sanitary material cost are similar with an annual cost of 530 euros, 492 euros, 450 euros respectively. Hypnotic and anxiolytic consumption appear to be correct with literature data with about 30% population exposed. CONCLUSION: Females are disabled about 10 years after males, many hospitalisation could be avoided with correct sanitary programs and finally and inverse correlation of drug consumption and hospitalisation is observed.

The drop-out evaluation is also important considering the relevant economic impact for NHS of an antipsychotic therapy discontinuation in terms of patient hospitalization and other related healthcare resources consumption. OBJECTIVE: To analyze the differences in the rates of drop-out from clinical trials between olanzapine and aripiprazole. METHODS: Literature search was based on MEDLINE, on Iowa-IDIS and Drugdex databases (1966-Dec 2004. Analysis included 12 randomized controlled trials (3.778 patients, 8 for olanzapine (2.559 patients and 4 for aripiprazole (1.219 patients. RCT inclusion criteria were: a Patients affected by schizophrenia; b Randomized assignment to olanzapine or aripiprazole treatment group; c Number of patients included in the treatment group higher than 100; d Drop-out frequency evaluation between 4th and 26th weeks of follow-up. RESULTS: The rate of treatment discontinuation was greater for aripiprazole than for olanzapine (42,2% vs. 31,6% respectively. The comparison between drop-out percentages is statistically significant (p<0,001. CONCLUSIONS: The incidence of drop-outs was better controlled in the olanzapine group of studies than in the aripiprazole group of studies.

    Full Text Available [“What may I hope?”. Starting points for an interpretation of hope in Kant’s thought]. In the Critique of Pure Reason Kant summarizes all the interests of reason in three famous questions: “1. What can I know? 2. What ought I to do? 3. What may I hope?”. The latter question opens the possibility for the reason to overcome its limits in the speculative use and postulates the unity between the kingdoms of freedom and nature. This article explores the function of hope in the sphere of morality and, in particular, in the transition from the subjective to the intersubjective level, focusing on the cooperation for achieving the purpose of the “moral republic” and of the “cosmopolitan world republic”.

    Directory of Open Access Journals (Sweden)

    Josef Seifert

    2012-09-01

    Full Text Available Nach dem Relativismus gibt es keine Urteile, welche absolut gesprochen wahr oder falsch wären. Am Beispiel des Selbstmords und der Verzweiflung als Reaktion Heinrich von Kleists auf den „transzendentalen Relativismus“ Kants werden die einschneidenden existentiellen Konsequenzen der relativistischen Leugnung der Absolutheit der Wahrheit dargelegt. Anhand konkreter Aussagen wird gezeigt, daß dieWahrheit einem Urteil absolut und allein in seinem Verhältnis zur Wirklichkeit, und nicht relativ auf irgendein denkendes Wesen zukommt und deshalb der Relativismus dem einsichtigen Wesen der Wahrheit widerspricht. Während der Skeptizismus nur die Erkennbarkeit der Wahrheit bezweifelt oder leugnet, deutet der „Relativismus“ den Begriff der Urteilswahrheit radikal um. Aus dem Wesen der Wahrheit als Übereinstimmung mit bestehenden Sachverhalten folgt die Absurdität und Undenkbarkeit des vom Relativismus umgedeuteten Wahrheitsbegriffs, in dem Wahrheit mit einem subjektiven Für-wahr-Halten gleichgesetzt wird. Hand in Hand mit ihrem Widerspruch zum einsichtigen Wesen der Wahrheit widerspricht sich die Aussage der Relativität der Wahrheit selber. Denn die Aussage „Alle Wahrheit ist relativ“ (auf den Einzelnen, auf einen historischen Verstehenshorizont, oder auch auf die ganze Menschheit beansprucht für sich selber und ihre zahlreichen Begründungen notwendigerweise genau jene Objektivität der Wahrheit, die sie für alle anderen Aussagen leugnet. Auch in der „Diktatur des Relativismus“ wird ein Widerspruch aufgewiesen. Denn wenn es keinen Unterschied zwischen „Wahr-sein“ und „Für Wahr-Halten“ mehr gibt, müsste ein totales laisser-faire, laissez-vivre folgen. In Wirklichkeit aber hat niemand eine so radikale politische Diktatur ausgeübt wie der essentiell relativistische Nationalsozialismus, Kommunismus und Faschismus, und übt der Relativismus auch im heutigen akademischen Leben eine Diktatur aus. Darin liegt eine paradoxe „Logik“ des Relativismus: denn ebenso wie er keinen rationalen Grund hat, eine Diktatur auszuüben und alles dulden müsste, hat er auch keinerlei Grund, selbst der schlimmsten Diktatur, Unterdrückung der Meinungsfreiheit, politischen Freiheit oder selbst der grauenvollsten Verletzung der Menschenwürde Widerstand zu leisten. Dieser paradoxe Widerspruch der politischen und akademischen Diktatur des Relativismus erweist gleichfalls die notwendige Falschheit des Relativismus. Abschliessend wird gezeigt, daß Russells und Tarskis universales Verbot der Selbstanwendung einer Theorie, welches sie von seiner berechtigten Anwendung auf empirische und bestimmte andere Aussagen, welche objektiv ein sich selber Ausnehmen vom Gegenstandsbereich der eigenen Aussage zulassen, auf alle allgemeinen Aussagen und Prinzipien ausdehnen, nicht, wie sie glauben, die Widerlegung des Relativismus aus seinem Selbstwiderspruch zunichtemacht, sondern vielmehr die Fundamente aller Logik zerstören würde. Ähnliches gilt für Heideggers und Gadamers nonchalante Behauptung, die Widerlegung des Relativismus aus seinem Selbstwiderspruch sei ein „plumper Überrumpelungsversuch“. Keine dieser Listen moderner Logiker und herablassenden Kritiken Heideggers können Platons, Aristoteles’, Augustins, Bonaventuras, Husserls und unsere zweite Widerlegung des Relativismus aus seinem inneren Widerspruch ungültig machen. Abstract According to general relativism there are no judgments that would be absolutely spoken true or false. The example of Heinrich von Kleist’s suicide and despair in reaction to Kant’s ‘transcendental relativism’ reveals the drastic existential consequences of the relativistic denial of the absoluteness of truth, when the latter is understood in its entire logical weight. On the basis of concrete statements it is shown that truth belongs to a judgment absolutely – solely based on its relation to reality – and not relatively to any thinking subject; to conceive it so, therefore, contradicts the nature of truth. Whereas skepticism only doubts or denies that truth can be known, a thesis refuted in the text, relativism radically ‘reinterprets’ and changes the content of the term ‘truth of the judgment.’ The absurdity and inconceivableness of the term ‘truth’ as reinterpreted by relativism in the sense of equating it with the subjective ‘holding X to be true’ follows from the intelligible nature of the truth of the judgment. Hand in hand with its contradiction to the nature of truth, the thesis of the relativity of truth contradicts itself. For the statement ‘(all truth is relative’ (to an individual, to a historical horizon of understanding, or also to mankind as such necessarily claims for itself as well as for its numerous reasons, premises, and conclusions of arguments exactly that objectivity of truth it keeps denying of all judgments. Also ‘the dictatorship of relativism’ exhibits a contradiction. On the one hand, if there is no difference between truth and ‘holding something to be true’, a total laissez faire, laissez vivre would have to follow. In reality however nobody exercised as radical a political dictatorship as the essentially relativistic National Socialism, communism and fascism; also in today’s academic life relativism exercises a kind of intellectual dictatorship. This demonstrates ‘a paradoxical logic’ of relativism: for just as it does not have any rational reason to exercise dictatorship and would have to tolerate every opinion or action, it also has no reason whatsoever to resist even the worst dictatorship and suppression of freedom of opinion and political liberty, or even the most gruesome violation of human dignity and torture. This paradoxical contradiction regarding the political and academic dictatorship of relativism proves the necessary falsehood and contradictory nature of relativism and the absurdity of its ‘dictatorship.’ Russell’s and Tarski’s universal prohibitions of the selfapplication of a theory extend the justified application of the ‘vicious-circle-principle’ (to empirical and certain other statements, which objectively permit or demand exempting a subject or statement from the range of its application and claim that no universal statements and principles can apply to themselves. This does not, as many modern logicians and meta-language theorists believe, constitute a dismantling of the refutation of relativism from its self-contradiction, but rather would destroy, if true, the foundations of all logic and is in no way necessary to avoid logical paradoxes and vicious circles. Something similar applies to Heidegger’s and Gadamer’s nonchalant statement that the refutation of relativism from its selfcontradiction is ‘a plump attempt to win by bullying and taking the opponent by surprise’. None of the ruses of modern logicians nor the condescending criticisms of Heidegger and Gadamer can render invalid Plato’s, Aristotle’s, Augustine’s, Bonaventure’s, Husserl’s, and our second refutation of relativism from its internal contradictions, a refutation of relativism that is justified by the eternal validity of the principle of contradiction and by the necessarily non-relative nature of propositional truth.

    2012-01-01

    Full Text Available This article wants to follow the path and development of “black subject” in the USA through the novels of the Afro-American writer Richard Wright. Written between the 50’s and 70’s, Wright's novels tell us about the segregation and humiliation inflicted by white men, but also the process of self-colonisation that the Afro-American – no longer slaves, but still not entirely free, neither de iure, nor de facto – subjected themselves to. By telling the stories of young boys struggling with their growing up - from their childhood to the first steps into a violent adulthood - Wright shows – in a way which is never inane and rhetorical, nor blindly optimistic – the need to overcome the old models and racist stereotypes, and builds his own work as a true Bildungsroman of the “black subject”.

Attraverso la comparazione di alcuni modelli per l'organizzazione a scaffale delle risorse, si individuerà la soluzione più economica e realistica per rappresentare le entità di FRBR. I principali risultati di questa analisi sono: la consapevolezza che le categorie isolate dal modello entità-relazione erano già state individuate da Ranganathan nel suo sistema bibliografico e che il numero di libro della classificazione Colon è il più rispondente alle entità di FRBR. Il numero di libro della classificazione Colon è in questa prospettiva migliore del sistema ideato da Cutter e Sanborn, poiché nel Catalogo Classificato ideato da Ranganathan risultano integrati entrambi gli aspetti della catalogazione (semantica e semiotica.

An elderly man with a history of several cardiovascular diseases was initially brought to the psychiatric outpatient department by his family because of worsening of recent memory, executive function, and mixed anxious-depressive mood. Gerstmann’s syndrome without obvious motor function impairment and dementia-like features could be observed at first. Emergent brain computed tomography scan revealed new left-middle cerebral artery infarction over the left posterior parietal lobe. This case reminds us that acute cerebral infarction involving the parietal lobe may present as Gerstmann’s syndrome accompanied by cognitive decline mimicking dementia. As a result, emergent organic workups should be arranged, especially for elderly patients at high risk for cerebral vascular accident.Keywords: Gerstmann’s syndrome, dementia, parietal lobe infarction

We have once more invited a guest columnist to give their views on various matters related to Analytical Chemistry in Europe. This year we have invited Professor Manfred Grasserbauer of the Vienna University of Technology to present some of the current challenges for European analytical chemistry. During the period 2002–2007 Professor Grasserbauer was Director of the Institute for Environment and Sustainability, Joint Research Centre of the European Commission, Ispra. There is no doubt that many challenges exist at the present time for all of us representing a major branch of chemistry, namely analytical chemistry.The global financial crisis is affecting all branches of chemistry but analytical chemistry in particular since our discipline by tradition has many close links to industry. We notice already now a decreased industrial commitment with respect to new research projects and sponsoring of conferences. It is therefore important that we strengthen our efforts and that we keep our presence at analytical chemistry meetings and conferences unchanged.Recent activities of DAC and details regarding the major analytical-chemistry event this year in Europe, Euroanalysis XV in Innsbruck, are also reported.

Mouffe’s diametrically opposed idea of a “conflictual consensus” is critically examined particularly for the claim that it promises to sublate contradictory claims in agonistic forms of conflict. A critical evaluation of this thesis refers to the question whether such a consensus unconditionally requires the renunciation of any unalienable claim.

    Full Text Available Sexualität und Fortpflanzung gehören zu den pubertätsassoziierten Themen, die im Zentrum des Interesses von Jugendlichen stehen – insbesondere bei Mädchen darüber hinaus auch Menstruation, Zyklus und Kinderwunsch. Dieses Interesse sollte von der Politik, der Schule und von Ärztinnen und Ärzten genutzt werden, jungen Mädchen ein umfassendes Bewusstsein für ihre Fähigkeit zu vermitteln, Kinder bekommen zu können und so dazu beizutragen, den eigenen Körper kennen und schätzen zu lernen. Unverzichtbar sind auch die Kenntnisse zur hormonellen Kontrazeption und zu den die Fruchtbarkeit gefährdenden STDs. Dies betrifft insbesondere die Chlamydien und die HPV-Impfung, damit sie ihren Körper schützen können und die individuelle Fertilität (= Fekundität nicht bereits auf der Wissensebene scheitert. Es muss zudem ins Bewusstsein gerückt werden, dass die Fruchtbarkeit in aller Regel heute früh einsetzt und wahrscheinlich zunächst im Interesse von Schulabschluss, Ausbildung und Berufstätigkeit über viele Jahre nicht genutzt wird. Das Wissen darum, dass auf der anderen Seite die Fähigkeit, schwanger werden zu können, jenseits des 30. Lebensjahr deutlich abzunehmen beginnt, hilft den Mädchen, den Kinderwunsch an der richtigen Stelle in der Biografie einordnen zu können (Verhaltensprävention. Elterngeld und Kitaplätze ermöglichen zwar vor allem gut ausgebildeten Frauen die Arbeitsmarktpartizipation, aber sie schaffen allein noch keine steigenden Geburtenraten. Solange das Familienleben den gleichen stressenden Ansprüchen an das Qualitätsmanagement unterworfen ist wie die Karriereplanung, sind damit junge Frauen und ihre Familien in aller Regel überfordert. Damit Jugendliche Mut haben zur Familiengründung und insbesondere intelligente und leistungsfähige Mädchen dieses Klima der Hierarchisierung von Berufs- und Familienleben nicht länger über Ausweichverhalten kompensieren müssen, bedarf es über die materielle Anerkennung hinaus vor allem eines gesamtgesellschaftlichen Traditionalisierungsschubes in der Anerkennung von Beziehungs- und Erziehungsleistung (Verhältnisprävention.

  13. l tornado che colpì la laguna di Venezia I ' l l Settembre 1970 Qualche considerazione intorno alla teoria elettrica dei tornado

    1972-06-01

    Full Text Available After a short description of the disastrous effects of the
    tornado which struck the Venice lagoon on September 11, 1970, the principal
    theories which in the centuries tried to account for the origin of such
    terrible vortexes, are reviewed. In particular, some remarks are given about
    the electrical theory of the tornadoes. It seems to the author that some features
    would be explained in a simple way by considering the tornado as a
    convectivo cell with electric currents of high intensity. Finally, after recalling
    the meteorological conditions preceding the tornado of September 11,
    its chief features are described.

    Full Text Available Cette étude réalisée en septembre 1996 dans le cadre du Projet d’Étude Participative AISA/IDESSA a permis de faire l’historique des activités halieutiques et la typologie de la pêche sur le lac Faé. La pêche dans ce réservoir est artisanale et de type individuel. Démarrée en 1980 avec l’implantation des pêcheurs étrangers originaires du Mali, cette activité est pratiquée par deux types d’acteurs : les professionnels (étrangers et les occasionnels (Bakwés. Les engins de pêche sont ceux classiquement utilisés dans les pêcheries continentales de Côte d’Ivoire : filets maillants, mono et multifilaments, nasses (grillagées, en filets ou en bambou et pièges en bambous de Chine. La densité des pêcheurs artisans sur le lac Faé est de 6,4 pêcheurs/km2, soit trois fois supérieure à la norme optimale de 2 pêcheurs/km2 admise par la législation ivoirienne Par conséquent, des mesures de gestion devraient être prises par la Direction de la Production Halieutique (DPH pour contrôler le flux migratoire des pêcheurs vers cette retenue, afin d’infléchir la densité observée. Le maintien ou l’accroissement de celle-ci pourrait engendrer une surexploitation rapide des stocks, et constituer une source potentielle de conflits entre étrangers et autochtones. A cet effet, des recommandations pour une pratique durable de la pêche sur cette retenue sont proposées.

    2015-12-01

    Full Text Available The iconographic research deals with the particular topic of the Holy Kinship, a common subject in the north of the Alps, but almost absent in Italy. Through a study about the historic and devotional grounds for the fortune of the theme in the transalpine area, especially in the Flemish and Rhenish ones, some suppositions will be stated, which explain the frequency of the Holy Kinship in the southern Piedmont and in Western Liguria. In these regions indeed Gandolfino da Roreto and Lorenzo Fasolo painted the only copies of the subject known in Italy. The study tries to deepen the relationships among artists, cities and committees of the artworks, by reconsidering the many times proposed connection between the Holy Kinship and the Immaculate Conception of the Virgin Mary, in order to attribute rather the reasons of the frequency of the subject to the social background of the patrons and to their thriving commercial business in the Netherlands and in the Northwest of Europe.

    The group of biologics for the treatment of rheumatic diseases is continuously growing. They have become an important option not only for treatment of so far untreatable chronic inflammatory or rheumatic disease, but also for juvenile idiopathic arthritis. In addition, the velocity and the degree of improvement is better than with to conventional therapies. Furthermore, toxicity and risks seem to be lower with higher safety and compatibility. Although the data are scarce, they are widely used. Therefore, the German Arbeitsgemeinschaft Kinder- und Jugendrheumatologie is updating the current recommendation for the treatment of juvenile idiopathic arthritis using biologics.

    Full Text Available The objective of this paper is to highlight reasons and effects of the longue durée on the close relationship that linked Italian and Spanish nations. We aim at focusing on changes, but also on the resistance of this relationship based on a dynamic process able to include continuity and transitions in European history and, then, gradually, in the global dimension. Our main purpose is to specify the long and variable trend of the relationships between the two nations during six centuries, starting from the sixteenth - the very beginning of the Spanish hegemony in the Mediterranean area - and continuing until nowadays and present time’s challenges. The essay, finally, aims at answering, even in a partial and necessarily incomplete way, a key question: after a long (“eternal”? history in common, can we find a shared identity between persistence and abrupt transitions?

Por encima de los aspectos concretos, los cristãos-novos trataron de conseguir que se introdujese en Portugal el procedimiento de la Inquisición española. La controversia quedó, en gran medida, centrada en la validez de los testigos singulares para probar el crimen de herejía. Por su parte, el Santo Oficio luso pugnó, durante los sesenta años, para mantener su autonomía y jurisdicción frente a las intromisiones de la Corona o de la Santa Sede.

  3. LA GESTION ASSOCIATIVE DE LA PÊCHE EN FRANCE : UNE ANALYSE ÉCONOMIQUE À PARTIR DU CAS DES SALMONIDÉS

    Directory of Open Access Journals (Sweden)

    LE GOFFE P.

    2004-07-01

    Full Text Available L’analyse économique et l’examen des quelques données empiriques disponibles en France incitent à se demander si la gestion associative permet de tirer suffisamment de bien-être de la pêche de loisir en eau douce. Notre analyse s’appuie sur le cas des salmonidés. D’une part, l’effort de pêche est probablement trop important sur les bons parcours faciles d’accès, ce qui peut entraîner des pertes de bien-être dues à la congestion. D’autre part, les propriétaires riverains ne sont pas suffisamment incités à améliorer la qualité de l’environnement, alors que les pêcheurs ont un consentement à payer pour des améliorations. Ces inefficacités s’expliquent par la conjonction de trois phénomènes. Tout d’abord, les droits de propriété, privés, sont atténués par des dispositions législatives. Ensuite, les associations ne contrôlent pas suffisamment l’effort de pêche individuel et collectif. Finalement, les politiques halieutiques sont centrées sur la protection de la ressource et sont, bien que nécessaires, insuffisantes pour maximiser la rente sociale tirée de la pêche. La régulation de l’effort de pêche et la négociation de certains services environnementaux sur la base du principe bénéficiaire-payeur permettraient d’améliorer le bien-être collectif. Des tarifs sociaux permettraient de maintenir l’équité dans l’accès.

    Directory of Open Access Journals (Sweden)

    Mauro Cardi

    2010-12-01

    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.

    Research suggests that Vietnam era veterans have a higher prevalence of hepatitis C virus (HCV) than other veterans and nonveterans. However, the reasons for this are unclear, since this research has been conducted among Department of Veterans Affairs (VA) patients and most veterans do not use the VA. The current study compares HCV risk factors between the Vietnam era veterans and nonveterans seen in 4 large non-VA systems to explain this disparity. A total of 4,636 HCV patients completed surveys in 2011-2012. Vietnam era veterans were defined as those who served in the military any time between 1964 and 1975. Bivariate tests followed by logistic regressions, and multivariable modeling were conducted to study risk factors among Vietnam era veterans and nonveterans. Since few veterans were female (~2 %), they were excluded. Among male respondents (N = 2,638), 22.5 % were classified as Vietnam era veterans. Compared to nonveterans, these patients were older (p Vietnam era veterans = 41.4 %, p = 0.06), only reported sex with men was significant (nonveterans = 2.4 % vs. Vietnam era veterans = 0.6 %, p = 0.013). In multivariate logistic regression controlling for age, education, country of birth, marital status and study site, no HCV risk factor was associated with Vietnam era veteran status. However, veterans were more likely to report "other" exposures were the source of infection than nonveterans (p Vietnam era veterans seen in non-VA facilities do not report a higher prevalence of common HCV risk factors, such as injection drug use, they are more likely to report "other" exposures, typically associated with military service, as the source of HCV infection.

Eight streams differently altered by human impact were studied: four small streams without weirs and impoundments, two regulated small streams and two larger regulated streams. The sampling sites were located in one kilometer streches of the upper, middle and lower reach of each small stream, respectively. In addition the gravel bars in several floodplain sections of larger streams were investigated. Altogether 592 quantitative samples of spiders were made. 7027 spiders (Araneae comprising 77 species were encountered. Only two species (Oedothorax agrestis, Pirata knorri make up more than 70 percent of all spiders captured. Erigone atra and Erigone dentipalpis were frequently foung along all streams investigated. While Diplocephalus permixtus and Diplocephalus protuberans were only encountered along the small streams, Oedothorax retusus and Pardosa amentata were predominantly recorded on gravelbars of large streams. Diplocephalus protuberans was recorded for the first time in Hesse. The mean abundances (median ranged between 4 and 28 individuals/m2. 198 individuals/m2 have been the maximum of abundance.

    A fluorescence microscopy on a basis of fluorescein diacetate and propidium iodide was used to investigate the persistence of primary conidia of Pandora delphacis (Entomophthorales) at combinated regimes of temperature (10~30℃) and relative humidity (51~100% RH). Examination of the conidia on glass coverslips sampled 24 h after discharge resulted in a survival rate of 42~81% at 51% RH, 69~89% at 74% RH, 70~95% at 85% RH, 67~100% at 90% RH, 76~100% at 95% RH, and 56~100% at 100% RH, respectively, varying with different temperature. Maintained at 10~30℃ for 4 mon, the rate of survial conidia remained 55~74% at 51%RH, 52~87% at 74% RH, 38~73% at 85% RH, and 1~65% at 90% RH, respectively. However, 7 d after discharge, few conidia were found surviving at 95% RH regardless of the temperature. The results indicate that the first 24 h after discharge was crucial to longer survival of P. delphacis conidia at the humidity of 74% RH whereas saturated or nearly saturated air was not favorable to their longer survival.%用荧光染色法研究了不同温度(10~30℃)和湿度(51~100%RH)组合条件下飞虱虫疠霉 Pandora delphacis分生孢子的存活率。在无放回抽样观察中,孢子弹射后第24 h的存活率在51%、74%、85%、90%、95%和100%RH与不同温度的组合中分别为42~81%、69~89%、70~95%、67~100%、76~100%和56~100%。存放4个月后,不同温度下的孢子存活率在51%、74%、85%和90%RH下分别为55~74%、52~87%、38~73%和1~65%。而在≥95% RH下孢子存活率24h后锐减,至第7 d几乎全部失活。以上结果表明,弹射后的飞虱虫疠霉孢子在头24 h的存活易受低湿影响,但存活下来的孢子能继续在低湿下存活较久;饱和或接近饱和的高湿度最不利孢子长久存活。

    Full Text Available Introduction and Objectives: The anesthesia in coronary surgery, using high sustained doses of fentanyl, leads to protracted postoperative extubation and stay. The assessment of an anesthesiastrategy for coronary surgery without extracorporeal circulation, in order to reduce the use of opioids and make possible an early extubation and a shorter post-surgical stay, was the objective of thiswork. Methods: 732 patients who underwent surgical myocardial revascularization without heartlung machine, from February 2003 to December 2007, using general anesthesia with intermittent boluses of fentanyl, with or without associated epidural anesthesia, were studied. Results: 625 surgical operations with general anesthesia in boluses and 107 adding peridural anesthesia were carried out. The average amount of fentanyl was 34.7 ml per patient in the first group and 24.9 ml when adding peridural anesthesia. Twenty seven patients were extubated in the operating room. The total average time was 8.6 hours (8.8 hours in the group where the anesthesia in boluses wasused and 6.7 hours for those with peridural anesthesia associated. The total average stay at the Intensive Care Unit was 40.1 hours. Conclusions: The intermittent anesthesia reduced the amount of fentanyl used in 86.6 percent when compared to the high sustained doses reported in a previous study. This made possible the early extubation of the patients, which increased due to the use of peridural anesthesia, and a decrease in average stay of the patient at the Intensive Care Unit.

    2014-06-01

    Full Text Available The development of guidelines for palliative care in the paediatric settings is judged to be still incomplete and characterized by many controversial issues; in order to explore the life-experience of individual health care professionals, we proposed a semi-structured questionnaire with open questions on end-of-life procedures to the staff members of the Paediatric Onco-hematology Ward of the University of Padua, of the Oncology Ward and in the Home Assistance Module of the Giannetta Gaslini Hospital, Genoa, both in Italy. This paper will focus on the responses provided to the third question: “In your opinion, can inducing the suspension of the state of consciousness be counted among end-of-life procedures? If so, how and when?”. Staff members were found to face challenging interactions at at least three levels: within the professional team, with respect to the parents and with respect to the adolescent patients. Among the most complex issues raised by the participants we found the moral distress sometimes experienced by nurses with respect to the decisions assumed by doctors, as stated by a nurse: “Everything is subjective in those 24 hours  (… and you are to do or not do certain things and it makes you feel distressed”. Second, it emerged that the relationship with the parents becomes very challenging when the two are not in agreement: “The father wants to give the morphine, but the mother secretly closes the drip”. Finally, the relationship of trust with the adolescent patients is under threat when they ‘want to know’ while parents seem to be unable to tolerate this degree of painful but essential self-consciousness in their ‘child’: “He locked me in the room and asked, ‘Am I dying?’, and I wanted to die at that point…”. Our study shows that health care professionals require not just guidelines but a tailor-made training and support which integrate much deeply the therapeutic as well as the moral and philosophical approaches to the issues raised by palliative care in paediatric settings.Articoli Selezionati del Congresso “Medicina Narrativa e Comunicazione nella Pratica Clinica” ·  Cagliari · 14 Aprile 2014 Guest Editors: Massimiliano Zonza, Vassilios Fanos, Gian Paolo Donzelli

    Malet, Régis

    2011-08-01

    Borders, translation and politics of difference: the hermeneutic task of comparative education - Governments are making increasing use of international comparisons as a tool to run and reform education systems, through the establishment of competency norms and assessment standards. In light of this trend, this paper wishes not only to reiterate the crucial distinction, made by Max Weber as early as 1922, between scientific research and political action, but also to recall the principles of separation and mediation from which the comparative approach in education derives. The concepts that comprise a language, that are disseminated and become established in a social world, are borne of history, of dynamic uses, and are culturally rooted. By neglecting this social and cultural provenance of words there is a danger that one can end up with a comparability based on functional equivalencies alone; although there are strong pressures in this direction, it is probably the surest way, in the words of Marcel Détienne, of "comparing the incomparable". The purely instrumental rationality that favours the spread of such frameworks or interpretative models appears indifferent to questions of meaning and culture, apart from being irrational on an axiological level, if we follow Weber. Strangeness or even `otherness' tends to be erased. One wonders therefore what issues are raised for the comparativist when the illusion of spontaneity in translation is reduced to a functional equivalence. In keeping with the researcher's responsibility to mediate, he/she must promote clarification and mutual understanding (inspired by C. Taylor), replacing the standardisation of words with a critical illumination of the semiotic variations generated by their use.

    COLLAS M.

    2007-07-01

    Full Text Available Depuis la fin du XIX° siècle, la distribution des écrevisses en France a connu de profonds bouleversements, et l’introduction d’écrevisses allochtones en provenance essentiellement du continent nord-américain, a irrémédiablement modifié le paysage astacologique français et européen. Les quatre enquêtes réalisées en France par le Conseil Supérieur de la Pêche depuis 1977, ont permis de suivre l’évolution des différentes espèces d’écrevisses recensées sur le territoire national, mettant à chaque fois en évidence la forte expansion des espèces exotiques et le recul des espèces natives. L’enquête de 2006 n’échappe pas à cette tendance et la situation de nos trois espèces d’écrevisses doit désormais être considérée comme alarmante. Deux de ces espèces se caractérisent par un statut de conservation proche de l’extinction (Austropotamobius torrentium et Astacus astacus alors que la troisième, Austropotamobius pallipes est « réfugiée » sur les secteurs apicaux des bassins versants, confinée sur des zones soumises aux premières manifestations du changement climatique et isolées par les espèces exotiques qui progressent de plus en plus vers l’amont. En effet, l’écrevisse du Pacifique (Pacifastacus leniusculus, mais aussi l’écrevisse rouge de Louisiane (Procamabrus clarkii, sont les espèces qui montrent la plus forte expansion géographique durant la période 2001-2006. Partout elles apparaissent comme des concurrents redoutables, plus agressifs, résistants aux pathologies, capables de coloniser des habitats variés…. Ces deux espèces en particulier étendent leur aire de répartition et colonisent chaque année de nouveaux départements, de nouveaux cours d’eau, éliminant par là même, les espèces autochtones. L’expansion des écrevisses introduites, l’arrivée récente en France d’une nouvelle espèce (Orconectes juvenilis et les modifications de la Loi autorisant dorénavant le transport à l’état vivant des « espèces susceptibles de provoquer des déséquilibres biologiques » pourraient sceller définitivement le sort des écrevisses endémiques, si aucune mesure n’est prise rapidement par les autorités, dans le cadre d’un plan d’action national « écrevisse ».

    A comprehensive hydrometeorological dataset is presented spanning the period 1 January 2011-31 December 2014 to improve the understanding of the hydrological processes leading to flash floods and the relation between rainfall, runoff, erosion and sediment transport in a mesoscale catchment (Auzon, 116 km2) of the Mediterranean region. Badlands are present in the Auzon catchment and well connected to high-gradient channels of bedrock rivers which promotes the transfer of suspended solids downstream. The number of observed variables, the various sensors involved (both in situ and remote) and the space-time resolution ( ˜ km2, ˜ min) of this comprehensive dataset make it a unique contribution to research communities focused on hydrometeorology, surface hydrology and erosion. Given that rainfall is highly variable in space and time in this region, the observation system enables assessment of the hydrological response to rainfall fields. Indeed, (i) rainfall data are provided by rain gauges (both a research network of 21 rain gauges with a 5 min time step and an operational network of 10 rain gauges with a 5 min or 1 h time step), S-band Doppler dual-polarization radars (1 km2, 5 min resolution), disdrometers (16 sensors working at 30 s or 1 min time step) and Micro Rain Radars (5 sensors, 100 m height resolution). Additionally, during the special observation period (SOP-1) of the HyMeX (Hydrological Cycle in the Mediterranean Experiment) project, two X-band radars provided precipitation measurements at very fine spatial and temporal scales (1 ha, 5 min). (ii) Other meteorological data are taken from the operational surface weather observation stations of Météo-France (including 2 m air temperature, atmospheric pressure, 2 m relative humidity, 10 m wind speed and direction, global radiation) at the hourly time resolution (six stations in the region of interest). (iii) The monitoring of surface hydrology and suspended sediment is multi-scale and based on nested catchments. Three hydrometric stations estimate water discharge at a 2-10 min time resolution. Two of these stations also measure additional physico-chemical variables (turbidity, temperature, conductivity) and water samples are collected automatically during floods, allowing further geochemical characterization of water and suspended solids. Two experimental plots monitor overland flow and erosion at 1 min time resolution on a hillslope with vineyard. A network of 11 sensors installed in the intermittent hydrographic network continuously measures water level and water temperature in headwater subcatchments (from 0.17 to 116 km2) at a time resolution of 2-5 min. A network of soil moisture sensors enables the continuous measurement of soil volumetric water content at 20 min time resolution at 9 sites. Additionally, concomitant observations (soil moisture measurements and stream gauging) were performed during floods between 2012 and 2014. Finally, this dataset is considered appropriate for understanding the rainfall variability in time and space at fine scales, improving areal rainfall estimations and progressing in distributed hydrological and erosion modelling.

    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.

    从4种不同稠油中分离沉淀出正戊烷沥青质,用红外光谱表征了其官能团结构,用1 H-N MR 结合相对分子质量及元素分析测定了沥青质的基本结构参数,并得出了沥青质的平均分子式,同时测定了沥青质的偶极矩来表征其极性。研究结果表明:稠油沥青质分子中杂原子的存在使其含有较多的极性基团,沥青质具有较大极性。杂原子含量越高,其极性越大,缔合性越强,缔合数越高。此外,用两种方法计算了沥青质的分子直径,结果表明:相对分子质量越大时,沥青质分子尺寸越大,但特性黏度法测得的分子直径与其选用的溶剂有关,且关联出的分子直径偏大,而相对密度和相对分子质量法能较好地反映分子颗粒尺寸。%Four kinds of asphaltenes were obtained from four different heavy oils with n-pentane as solvent.Their functional structures were characterized by FTIR spectroscopy,and the basic structural parameters of the asphaltenes were determined by 1 H-NMR,then the average molecular formula of the asphaltene were given by molecular weight and element content.The dipole moments were also meas-ured to indicate the polarities of the asphaltene molecules.The results show that the presence of het-eroatom in asphaltene makes the asphalt form the polar groups with high polarity,and the higher the content of impurity atoms,the greater the polarity,the stronger the association,the higher the associa-tion numbers.In addition,molecular diameters were measured by two methods:intrinsic viscosity method,and relative density and relative molecular mass method.With the increase of relative molecu-lar mass,the molecular size of asphaltene becomes larger.However,the molecular diameter measured by viscosity method is related to the selected solvents and usually is larger than the size obtained by rela-tive density and relative molecular mass method,and the latter method can well reflect the molecular size.

  12. High resolution analysis of uranium and thorium concentration as well as U-series isotope distributions in a Neanderthal tooth from Payre (Ardèche, France) using laser ablation ICP-MS

    Science.gov (United States)

    2008-11-01

    We have mapped U ( 238U) and Th ( 232Th) elemental concentrations as well as U-series isotope distributions in a Neanderthal tooth from the Middle Palaeolithic site of Payre using laser ablation ICP-MS. The U-concentrations in an enamel section varied between 1 and 1500 ppb. The U-concentration maps show that U-migration through the external enamel surface is minute, the bulk of the uranium having migrated internally via the dentine into the enamel. The uranium migration and uptake is critically dependent on the mineralogical structure of the enamel. Increased U-concentrations are observed along lineaments, some of which are associated with cracks, and others may be related to intra-prismatic zones or structural weaknesses reaching from the dentine into the enamel. The uranium concentrations in the dentine vary between about 25,000 and 45,000 ppb. Our systematic mapping of U-concentration and U-series isotopes provides insight into the time domain of U-accumulation. Most of the uranium was accumulated in an early stage of burial, with some much later overprints. None of the uranium concentration and U-series profiles across the root of the tooth complied with a single stage diffusion-adsorption (D-A) model that is used for quality control in U-series dating of bones and teeth. Nevertheless, in the domains that yielded the oldest apparent U-series age estimates, U-leaching could be excluded. This means that the oldest apparent U-series ages of around 200 ka represent a minimum age for this Neanderthal specimen. This is in good agreement with independent age assessments (200-230 ka) for the archaeological layer, in which it was found. The Th elemental concentrations in the dental tissues were generally low (between about 1 and 20 ppb), and show little relationship with the nature of the tissue.

    1999-01-01

    Ma chi ha detto che la fine della fisica è vicina? Che tutto quello che c'era da scoprire è già stato scoperto? E che le generazioni future potranno solo precisare e raffinare, e mai negare o arricchire le attuali teorie? Questo libro si contrappone a pensatori come Heisenberg, Feyman e Hawking che hanno predetto la morte della fisica. L'autore sostiene che grandi progressi sono possibili, ma che il prezzo da pagare per realizzarli è una modifica radicale delle basi della fisica moderna, in particolare abbandonando l'indeterminismo, la non località (paradosso di Einstein, Podolsky e Rosen) e lo stesso principio di relatività.

    Two-component signal transduction systems are widespread in prokaryotes and control numerous cellular processes. Extensive investigation of sensor kinase and response regulator proteins from many two-component systems has established conserved sequence, structural, and mechanistic features within each family. In contrast, the phosphatases which catalyze hydrolysis of the response regulator phosphoryl group to terminate signal transduction are poorly understood. Here we present structural and functional characterization of a representative of the CheC/CheX/FliY phosphatase family. The X-ray crystal structure of Borrelia burgdorferi CheX complexed with its CheY3 substrate and the phosphoryl analogue BeF{sub 3}{sup -} reveals a binding orientation between a response regulator and an auxiliary protein different from that shared by every previously characterized example. The surface of CheY3 containing the phosphoryl group interacts directly with a long helix of CheX which bears the conserved (E - X{sub 2} - N) motif. Conserved CheX residues Glu96 and Asn99, separated by a single helical turn, insert into the CheY3 active site. Structural and functional data indicate that CheX Asn99 and CheY3 Thr81 orient a water molecule for hydrolytic attack. The catalytic residues of the CheX-CheY3 complex are virtually superimposable on those of the Escherichia coli CheZ phosphatase complexed with CheY, even though the active site helices of CheX and CheZ are oriented nearly perpendicular to one other. Thus, evolution has found two structural solutions to achieve the same catalytic mechanism through different helical spacing and side chain lengths of the conserved acid/amide residues in CheX and CheZ.

    Full Text Available Abstract Background The taxis signaling system of the extreme halophilic archaeon Halobacterium (Hbt. salinarum differs in several aspects from its model bacterial counterparts Escherichia coli and Bacillus subtilis. We studied the protein interactions in the Hbt. salinarum taxis signaling system to gain an understanding of its structure, to gain knowledge about its known components and to search for new members. Results The interaction analysis revealed that the core signaling proteins are involved in different protein complexes and our data provide evidence for dynamic interchanges between them. Fifteen of the eighteen taxis receptors (halobacterial transducers, Htrs can be assigned to four different groups depending on their interactions with the core signaling proteins. Only one of these groups, which contains six of the eight Htrs with known signals, shows the composition expected for signaling complexes (receptor, kinase CheA, adaptor CheW, response regulator CheY. From the two Hbt. salinarum CheW proteins, only CheW1 is engaged in signaling complexes with Htrs and CheA, whereas CheW2 interacts with Htrs but not with CheA. CheY connects the core signaling structure to a subnetwork consisting of the two CheF proteins (which build a link to the flagellar apparatus, CheD (the hub of the subnetwork, two CheC complexes and the receptor methylesterase CheB. Conclusions Based on our findings, we propose two hypotheses. First, Hbt. salinarum might have the capability to dynamically adjust the impact of certain Htrs or Htr clusters depending on its current needs or environmental conditions. Secondly, we propose a hypothetical feedback loop from the response regulator to Htr methylation made from the CheC proteins, CheD and CheB, which might contribute to adaptation analogous to the CheC/CheD system of B. subtilis.

    A coupled elastic-poroelastic model for the simulation of the PDL and the adjacent tooth is presented. A poroelastic constitutive material model for the periodontal ligament (PDL) is derived. The solid phase is modeled by means of a Fung material law, accounting for large displacements and strains. Numerical solutions are performed by means of a multigrid Newton method to solve the arising large nonlinear system. Finally, by means of numerical experiments, the biomechanical response of the PDL is studied. In particular, the effect of the hydraulic conductivity and of the mechanical parameters of a Fung potential is investigated in two realistic applications.

    2014-01-01

    This work develops a model for thermally induced damage from high current flow through biological tissue. Using the first law of thermodynamics, the balance of energy produced by the current and the energy absorbed by the tissue are investigated. The tissue damage is correlated with an evolution law that is activated upon exceeding a temperature threshold. As an example, the Fung material model is used. For certain parameter choices, the Fung material law has the ability to absorb relatively significant amounts of energy, due to its inherent exponential response character, thus, to some extent, mitigating possible tissue damage. Numerical examples are provided to illustrate the model's behavior.

La pianificazione è un processo continuo, che si ripete ciclicamente nella vita di una azienda e che richiede una grande partecipazione da parte dei dirigenti e del resto del personale ma è, anche, un importante strumento di comunicazione che coinvolge tutti quelli che possono indirizzare l’azienda.

  4. Variazioni ed identità: la genetica tra determinismo e libertà

    OpenAIRE

    Tranchesi, Gregory

    2011-01-01

    Il presente lavoro prende le mosse da un’analisi filosofica del determinismo genetico sia nella forma che ha preso negli ambiti del razzismo scientifico e dell’eugenetica classica che nel paradigma che sembra configurarsi nella nuova eugenetica americana. L’esigenza di tale analisi nasce dalla considerazione che il modello deterministico dell’agire umano e la concezione meccanicistica del mondo risultano non aver mai abbandonato la cultura moderna e contemporanea, nonostante l’avvento della r...

Una continuità che non si risolve nell' “immobilità” o nella “arretratezza” dei suoi tratti ma che sembra tradursi in un sforzo singolare di autoconservazione che anche nelle pratiche del risiedere spinge il singolo a ritagliarsi la parte di mondo che gli spetta, facendo della casa ogni volta suo “primo universo”.

    2002-01-01

    La significativa ripresa dell’indagine comparativa che si registra a partire dagli anni Settanta, che segna il superamento della ‘fase nazionalista’, è anche il risultato di una serie di sviluppi nelle tecniche di ricerca avvenuti nei decenni precedenti. E’ in questo periodo che appaiono lavori, come quello di Przeworki e Teune (1970) sul versante quantitativo o di Theda Skocpol (1979) su quello qualitativo, che susciteranno un ampio dibattito sul come e il perché della comparazione. Negli ul...
