Monotone independence, comb graphs and Bose-Einstein condensation

The adjacency matrix of a comb graph is decomposed into a sum of monotone independent random variables with respect to the vacuum state. The vacuum spectral distribution is shown to be asymptotically the arcsine law as a consequence of the monotone central limit theorem. As an example the comb lattice is studied with explicit calculation

Carcinome epidermoïde du larynx chez la femme

Le cancer du larynx est assez rare chez la femme. Cependant, il risque d’être en recrudescence à cause de l’augmentation du tabagisme féminin. Peu de travaux se sont consacrés à rechercher les spécificités du cancer du larynx chez la femme.But: Analyser le profil épidémiologique et clinique des femmes porteuses d’un carcinome épidermoïde du larynx et dégager les caractéristiques thérapeutiques, évolutives et les facteurs pronostiques chez cette population.Méthodes: étude rétrospective portant sur 50 femmes prises en charge pour un carcinome épidermoïde du larynx sur une période de treize ans (1994-2006).Résultats : L’âge moyen de nos patientes était de 63,5 ans. L’intoxication tabagique était retrouvée chez 32,6% des patientes. Chez 30% de nos patientes aucun facteur de risque n’a été retrouvé. Les signes cliniques étaient dominés par la dysphonie suivie de la dyspnée et la dysphagie. Les tumeurs prenaient naissanceau dépend de l’étage glottique dans 55,8% des cas. Nous avons relevé que 60,4% des tumeurs étaient vus à un stade évolué T3-T4 et que 95,3% des tumeurs étaient initialement classées N0. La chirurgie a été pratiquée chez 47,5% des patientes tandis que 16,2% ont reçu une radio-chimiothérapie. La survie globale cumulée était de 78,8% à 3 ans et de 73,5% à 5 ans.Conclusion : L’absence des facteurs de risque classiques chez un grand nombre de nos patientes laisse supposer le rôle d’autres facteurs étiopathogéniques dans la genèse du cancer du larynx chez la femme. Toute dysphonie chez la femme doit être explorée même en l’absence de facteurs de risque. La prise en charge et le pronostic semblent superposables à celui de l’homme.Mots clés : Tumeur – Larynx – Femme – Epidémiologie – TabagismeLaryngeal cancer is quite uncommun in women. However, it may be on the rise due to the increase in smoking among women. Few studies have been devoted to find the specifics of laryngeal cancer in women.Purpose: to analyze the epidemiological and clinical profile of squamous cell carcinoma of the larynx in women, and to identify therapeutic characteristics and prognostic factors in this population.Methods: retrospective study of 50 womens treated for squamous cell carcinoma of the larynx over a period of thirteen years (1994- 2006).Results: The mean age of our patients was 63.5 years. The tobacco abuse was found in 32.6% of patients. In 30% of our patients no risk factors were found. Clinical signs were dominated by dysphonia followed by dyspnea and dysphagia. Primary tumor was localized in glottis in 55.8% of cases. We found that 60.4% of tumors were seen at an advanced stage T3-T4 and 95.3% of the tumors were initially classified N0. The surgery was performed in 47.5% of patients, while 16.2% received chemoradiotherapy. The cumulative overall survival was 78.8% at 3 years and 73.5% at 5 years.Conclusion: The absence of conventional risk factors in a large number of our patients suggests the role of other etiologic factors in the genesis of laryngeal cancer in women. Every dysphonia in women should be explored even in the absence of risk factors. The  management and prognosis seem congruent with that of man.Key words: Tumor-larynx-women-epidemiology-smokin

Yeast biota of naturally fermented black olives in different brines made from cv. Gemlik grown in various districts of the Cukurova region of Turkey

In this study, the yeast microbiota of naturally fermented black olives made from cv. Gemlik, grown in three different districts of the Çukurova region of Turkey, were investigated. Fermentations were conducted for 180 days in three different brines, including NaCl 10% w/v, NaCl 8% w/v and NaCl 8% w/v added with glucose 0.5%. In total, 223 yeasts were isolated and then identified by PCR–RFLP analysis of the 5.8S ITS rRNA region and sequence information for the D1/D2 domains of the 26S rRNA gene. A broad range of yeast biodiversity was identified, including eight genera and nine species. Candida boidinii (41%), Wickerhamomyces anomalus (32%) and Saccharomyces sp. (18%) were predominant yeasts throughout the fermentations. To a lesser extent, the other species, Candida aaseri, Meyerozyma sp., Zygoascus hellenicus, Pichia kudriavzevii, Schwanniomyces etchellsii and Candida atlantica were also members of the olive-fermenting microbiota. In Tarsus and Bahçe districts C. boidinii and in Serinyol district Saccharomyces sp. were the most frequently identified species. W. anomalus was the most frequently isolated species (by 48% of total yeasts) in NaCl 10% brines. C. boidinii was the most dominant species in the brines, including NaCl 8% and NaCl 8% + glucose 0.5%, with frequencies of 42% and 61%, respectively. At the end of the 180 days of fermentation, total acidity values of the brines were in the range 1.04–8.1 g/l lactic acid. Copyright © 2016 John Wiley & Sons, Ltd

Synthesis of novel biocomposite powder for simultaneous removal of hazardous ciprofloxacin and methylene blue: Central composite design, kinetic and isotherm studies using Brouers-Sotolongo family models

Over the past decades, extensive efforts have been made to use biomass-based-materials for wastewater-treatment. The first purpose of this study was to develop and characterize regenerated-reed/reed-charcoal (RR-ChR), an enhanced biosorbent from Tunisian-reed (Phragmites-australis). The second aim was to assess and optimize the RR-ChR use for the removal of binary ciprofloxacin antibiotic (CIP) and methylene blue dye (MB), using Central Composite Design under Response Surface methodology. The third purpose was to explain the mechanisms involved in the biosorption-process. The study revealed that the highest removal-percentages (76.66 % for the CIP and 100 % for the MB) were obtained under optimum conditions: 1.55 g/L of adsorbent, 35 mg/L of CIP, 75 mg/L of MB, a pH of 10.42 and 115.28 min contact time. It showed that the CIP biosorption mechanism was described by Brouers–Sotolongo-fractal model, with regression-coefficient (R2) of 0.9994 and a Person’s Chi-square (X2) of 0.01. The Hill kinetic model better described the MB biosorption (R2 = 1 and X2 = 1.0E-4). The isotherm studies showed that the adsorbent surface was heterogeneous and the best nonlinear-fit was obtained with the Jovanovich (R2 = 0.9711), and Brouers–Sotolongo (R2 = 0.9723) models, for the CIP and MB adsorption, respectively. Finally, the RR-ChR lignocellulosic-biocomposite-powder could be adopted as efficient and cost-effective adsorbent

Independence arising from interacting Fock spaces and related central limit theorem

We present the notion of projective independence, which abstracts, in an algebraic setting, the factorization rule for the vacuum expectation of creation-annihilations-preservation operators in interacting Fock spaces described in [3]. Furthermore, we give a central limit theorem based on such a notion and a Fock representation of the limit process

A constructive boolean central limit theorem

We give a construction of the creation, annihilation and number processes on the Boolean Fock space by means of a quantum central limit theorem starting from creation, annihilation and number processes with discrete time

Generic Fock Quantum Markov Semigroups with Instantaneous States

We construct a generic quantum Markov semigroup with instantaneous states exploiting the invariance of the diagonal algebra and the explicit form of the action of the pre-generator on off-diagonal matrix elements. Our semigroup acts on a unital C*-algebra and is strongly continuous on this algebra (Feller property). We discuss the generic hydrogenic atoms as an example
