Coherence in amalgamated algebra along an ideal

Let $f: A\rightarrow B$ be a ring homomorphism and let $J$ be an ideal of $B$. In this paper, we investigate the transfert of the property of coherence to the amalgamation $A\bowtie^{f}J$. We provide necessary and sufficient conditions for $A\bowtie^{f}J$ to be a coherent ring

Anévrysme et Pseudo-anévrysme du ventricule gauche

La gravité de l’infarctus du myocarde réside dans ses complications. Certainement, on avait une importante réduction dans leurs incidences grâce  à  l’amélioration de la prise en charge médicale et l’avènement des méthodes de reperfusion précoce, mais il persiste un taux considérable de complications qui posent un problème diagnostic mais surtout thérapeutique. Parmi eux, il existe l’anévrysme et le pseudo-anévrysme du ventricule gauche. Ces deux complications relativement rares sont souvent méconnues, d’où l’intérêt d’en connaître les modalités de prise en charge diagnostique et thérapeutiques

The susceptibility of Escherichia coli strains to essential oils of Rormarinus officinalis and Eucalyptus globulus

Essential oils are frequently used for flavour and fragrance in the perfume, pharmaceutical, cosmetic and food industries. They are also suitable raw material for production of new synthetic agents. The antibacterial activity of the essential oils obtained by steam distillation of Rosmarinus officinalis L and Eucalyptus globules collected in south Morocco was studied by micro-atmospheric technique against Escherichia coli CIP54127 and E. coli isolated from urine and resistant to several antibiotics. Both essential oils were effective against the two strains bacteria in particularly against E. coli CIP54127. MIQ of both oils ranged from 60 to 70 ìl for both bacteria. In conclusion, results show that essential oils are effective and could be considered as a natural antimicrobial source that can be used on production of natural antimicrobial agents

Compact localized boundary states in a quasi-1D electronic diamond-necklace chain

Zero-energy modes localized at the ends of one-dimensional (1D) wires hold great potential as qubits for fault-tolerant quantum computing. However, all the candidates known to date exhibit a wave function that decays exponentially into the bulk and hybridizes with other nearby zero-modes, thus hampering their use for braiding operations. Here, we show that a quasi-1D diamond-necklace chain exhibits a completely unforeseen type of robust boundary state, namely compact localized zero-energy modes that do not decay into the bulk. We theoretically engineer a lattice geometry to access this mode, and experimentally realize it in an electronic quantum simulator setup. Our work provides a general route for the realization of robust and compact localized zero-energy modes that could potentially be braided without the drawbacks of hybridization

Factors of interrupting chemotherapy in patients with Advanced Non-Small-Cell Lung Cancer

<p>Abstract</p> <p>Background</p> <p>Little is known about prognosis of metastatic patients after receiving a first-line treatment and failure. Our group already showed in pre-treated patients enrolled in phase I clinical trials that a performance status (PS) > 2 and an LDH > 600 UI/L were independent prognostic factors. In this prospective study, which included 45 patients, we identified clinical and biological variables as outcome predictors in metastatic Non-Small Cell lung cancer after first line chemotherapy were identified.</p> <p>Findings</p> <p>Forty-five patients that were previously treated for metastatic disease from 12/2000 to 11/2005 in the comprehensive cancer centre (Centre Léon Bérard). Clinical assessment and blood parameters were recorded and considered. Patient prognostic factors for overall survival (OS) with a 0.05-significance level in univariate analysis were entered in a multivariate Cox model for further analysis.</p> <p>Patients' median age was 58.5 years (range: 37 - 76). Sixty two percent of the patients were PS = 0 or 1. After inclusion, nine patients received second-line (22.5%), and two received third-line chemotherapy (5%). Univariate analysis showed that the factors associated with reduced OS were: PS > 2, weight loss >10%, more than one line of chemotherapy treatment and abnormal blood parameters (hemoglobin (Hb), platelet and neutrophils counts). Multiple regression analysis confirmed that PS > 2 and abnormal hemoglobin were independent predictors for low overall survival. According to the presence of none (33%), 1 (37%) and 2 (30%) prognostic factors, median OS were 12, 5 and 2 months respectively.</p> <p>Conclusion</p> <p>From this prospective study, both PS and anemia were found as independent determinants of survival, we found that both PS and anemia were independent determinants of survival. The combination of poor PS and anemia is an effective strategy to predict survival in the case of patients with metastatic NSCLC receiving further treatment after the first line.</p

Toxicity of south Morocco Rosmarinus officinalis essential oil: antibacterial and histopathological effects

Le romarin (Rosmarinus officinalis) possède de nombreuses propriétés médicinales. Il est connu pour ses effets antimicrobiens et anti-oxydatifs. Le but de ce travail est d’étudier la toxicité de son huile essentielle (HE) via un test antibactérien selon la technique de micro-atmosphère et un autre histopathologique au niveau des organes de souris (Swiss albinos). L’analyse de la composition chimique de cette HE a été effectuée par CPG. Les constituants majoritaires de l’HE de R. officinalis sont le 1,8-cinéole (42%), l’alpha-pinène (11,92%) et le camphre (13.99%). Les quantités minimales inhibitrices des souches bactériennes testées varient entre 40 ?l et 90 ?l. Au plan histopathologique, une dilatation des alvéoles pulmonaires et une hypertrophie des cellules corticales et médullaires des surrénales ont été relevées. En conclusion, l’HE de R. officinalis ne présente pas de toxicité à la dose 50 ?l/g mais possède des effets stimulants des glandes surrénales et du système respiratoire

Kroniek van het Migratierecht

Eindelijk een lichtpuntje in de voortdurende Europese migratiecrisis: Duitsland en Frankrijk hebben aangegeven vrijwillig asielzoekers die zijn aangetroffen in internationale wateren te willen hervestigen. Voor het overige wordt er stevig doorgewerkt aan het dichttimmeren van de buitengrenzen van de EU, databestanden worden gekoppeld maar het herziening van het pakket regelgeving loopt vooralsnog vast op onenigheid over herziening van de Dublinverordening. Ondertussen biedt het Hof van Justitie van de EU waar nodig soelaas en is Nederland door het Hof op de vingers getikt wegens de te strenge eisen die aan gezinshereniging worden gesteld
