    Lead remediation was achieved using simple cost, effective and eco-friendly way from industrial wastewater. Phragmitesaustralis (P.a) (Iraqi plant), was used as anovel biomaterial to remove lead ions from synthesized waste water. Different parameters which affected on adsorption processes were investigated like adsorbent dose, pH, contact time, and adsorbent particle size, to reach the optimized conditions (maximum adsorption). The adsorption of Pb (?) on (P.a) involved fast and slow process as a mechanism steps according to obey two theoretical adsorption isotherms; Langmuir and Freundlich. The thermos dynamic adsorption parameters were evaluated also. The (?H) obtained positive value that meanes adsorption of lead ions was an endothermic processwhile (?G)values were negative which means that adsorption of lead ions was a spontaneous process and the decrease in (?G) with temperature increasing revealed that lead ions adsorption on (P.a) became favorable with temperature increasin

    The C language is widely used for developing tools in various application areas, and a number of C software tools are used for critical systems, such as medicine, transport, etc. Correspondingly, the security of such programs should be thoroughly tested, i.e., it is important to develop techniques for detecting vulnerabilities in C programs. In this paper we present an approach for dynamic detection of software vulnerabilities using the SPIN model checker. We discuss how this approach can be implemented in order to detect automatically C code vulnerabilities and illustrate a proposed technique for a number of C programs which are widely used in a number of applications.Предлагается метод тестирования безопасности С программ с использованием широко известного верификатора SPIN. Обсуждаются классы уязвимостей в С программах, которые могут быть обнаружены с использованием предложенного подхода. Приводятся результаты компьютерных экспериментов по обнаружению уязвимостей в студенческих программных реализациях алгоритмов работы с массивами

    Antimicrobial resistance among migrants in Europe: a systematic review and meta-analysis

    BACKGROUND: Rates of antimicrobial resistance (AMR) are rising globally and there is concern that increased migration is contributing to the burden of antibiotic resistance in Europe. However, the effect of migration on the burden of AMR in Europe has not yet been comprehensively examined. Therefore, we did a systematic review and meta-analysis to identify and synthesise data for AMR carriage or infection in migrants to Europe to examine differences in patterns of AMR across migrant groups and in different settings. METHODS: For this systematic review and meta-analysis, we searched MEDLINE, Embase, PubMed, and Scopus with no language restrictions from Jan 1, 2000, to Jan 18, 2017, for primary data from observational studies reporting antibacterial resistance in common bacterial pathogens among migrants to 21 European Union-15 and European Economic Area countries. To be eligible for inclusion, studies had to report data on carriage or infection with laboratory-confirmed antibiotic-resistant organisms in migrant populations. We extracted data from eligible studies and assessed quality using piloted, standardised forms. We did not examine drug resistance in tuberculosis and excluded articles solely reporting on this parameter. We also excluded articles in which migrant status was determined by ethnicity, country of birth of participants' parents, or was not defined, and articles in which data were not disaggregated by migrant status. Outcomes were carriage of or infection with antibiotic-resistant organisms. We used random-effects models to calculate the pooled prevalence of each outcome. The study protocol is registered with PROSPERO, number CRD42016043681. FINDINGS: We identified 2274 articles, of which 23 observational studies reporting on antibiotic resistance in 2319 migrants were included. The pooled prevalence of any AMR carriage or AMR infection in migrants was 25·4% (95% CI 19·1-31·8; I2 =98%), including meticillin-resistant Staphylococcus aureus (7·8%, 4·8-10·7; I2 =92%) and antibiotic-resistant Gram-negative bacteria (27·2%, 17·6-36·8; I2 =94%). The pooled prevalence of any AMR carriage or infection was higher in refugees and asylum seekers (33·0%, 18·3-47·6; I2 =98%) than in other migrant groups (6·6%, 1·8-11·3; I2 =92%). The pooled prevalence of antibiotic-resistant organisms was slightly higher in high-migrant community settings (33·1%, 11·1-55·1; I2 =96%) than in migrants in hospitals (24·3%, 16·1-32·6; I2 =98%). We did not find evidence of high rates of transmission of AMR from migrant to host populations. INTERPRETATION: Migrants are exposed to conditions favouring the emergence of drug resistance during transit and in host countries in Europe. Increased antibiotic resistance among refugees and asylum seekers and in high-migrant community settings (such as refugee camps and detention facilities) highlights the need for improved living conditions, access to health care, and initiatives to facilitate detection of and appropriate high-quality treatment for antibiotic-resistant infections during transit and in host countries. Protocols for the prevention and control of infection and for antibiotic surveillance need to be integrated in all aspects of health care, which should be accessible for all migrant groups, and should target determinants of AMR before, during, and after migration.

    Modèle de prédiction semi-macroscopique pour les véhicules de transport en commun en milieu urbain

    No full text
    Traduire la progression des Îhicules de transport en commun dans un vaste réseau urbain, contrôlé par des feux tricolores, en un modèle mathématique est devenu une nécessité. Le modèle peut avoir deux usages principaux : d'une part, cela permet de comprendre et d'analyser un phénomène aussi complexe comme la circulation des Îhicules de transport en commun. D'autre part, le modèle peut servir comme un prédicteur dans une stratégie de régulation du trafic. C'est ce dernier point qui fera l'objet du modèle présenté dans cet article. Le modèle a pour objectif de décrire la progression d'un Îhicule de transport en commun dans un grand réseau routier urbain en fonction de la demande du trafic des Îhicules particuliers et des durées des feux verts de chaque ligne de feu traversée par le Îhicule. Ce modèle doit satisfaire deux objectifs souvent contradictoires : la précision et la simplicité. Les résultats des simulations effectuées sur un large réseau urbain ont montré que le modèle développé est cohérent. Elles ont permis aussi de Îrifier qu'il est bien adapté pour être utilisé comme prédicteur dans une stratégie de régulation en temps réel du trafic
