The decision making process to adopt mobile learning is influenced by many factors. On account of this, studies focused on evaluating the acceptance of mobile learning have found that usefulness and usability perceived have been consolidating by the main predictors of acceptance of mobile learning. In order to explore the set out issues, it seeks to examine the attitudes against the acceptance of mobile learning in students of Economics and Administrative Sciences of Metropolitan Institute of Technology (ITM in Spanish) of Medellin-Colombia. \nAn exploratory type research was conducted using a questionnaire given to 325 students of the Economics and Administrative Sciences School of ITM. Through this questionnaire, it seeks to identify the influence of usefulness and usability perceived against the implementation of mobile learning.\nThe results of the variation analysis of normative beliefs and attitudes toward mobile learning is laid out putting the respondents into groups which are available to compare their responses to differentiate them respect to categories such as gender, experience in e -learning, age and the number of semesters taken.

Periodontitis is a set of inflammatory diseases characterized by loss of connective tissue attachment and supporting bone around the teeth, which result in the apical migration of the junctional epithelium and the formation of deepened periodontal pockets. If left untreated it can lead to the loosening and subsequent loss of teeth. Early diagnosis and treatment of progressive periodontitis is important because of the irreversible nature of this disease. Thus the long-term aim is the treatment and prevention of periodontal disease. Clinical measurements used in diagnosis of periodontal diseases are often of limited usefulness in that they are indications of previous periodontal disease rather than present disease activity. The development of a test for most mediators associated with periodontal disease may serve as a useful method for identifying and predicting future progression. Biochemical mediators in oral fluids such as saliva and gingival crevicular fluid (GCF) are highly beneficial, due to the non-invasive and simple nature of their collection. They help in the determination of inflammatory mediator levels, as they are good indicators of inflammatory activity. This review analysed the potential array of salivary and gingival crevicular fluid (GCF) biomarkers, based on the diagnosis and prognosis of active periodontal disease.

The purpose of the study is to explore the effect of music in the class room on enhancing vocabulary building. The study was conducted among 77 undergraduate Engineering Students of West Tirunelveli. A qualitative survey design was used in this study. The study revealed that Listening Music in the class room method (LMCM) helps the learner to recall the targeted words, motivates, entertains the students in the class room and offers right pronunciation practice too .The study also found that the Listening lecture method (LLM) could not help the learners to recall the vocabularies and makes learners boredom in the class room and it allows them to learn local dialects rather standard pronunciation. Recommendations were made to use this effective method (LMCM) in the class room in order to build vocabulary skills effectively. There is no doubt that a strong relationship between Music and Second language Acquisition (SLA).

Abstract\nIntroduction The incidence of infection and intestinal colonization with vancomycin\nresistant enterococci (VRE) is increasing in many countries in the last decade. Concerning the\ndifficult antimicrobial treatment of infections caused by VRE, decreasing the incidence and\nprevalence of these infections is an important factor in VRE-induced morbidity and mortality\ncontrol. The objective of the study was to determine the prevalence of gastrointestinal\ncolonization with Vancomycin-Resistant Enterococci in hospitalized and outpatients and to\ndetermine the genetic base of the vancomycin resistance in VRE isolates. Material and\nmethods 780 specimens were investigated for the gastrointestinal carriage of vancomycinresistant\nenterococci (VRE). Susceptibility to vancomycin was tested in all isolates of\nEnterococcus, by disk-diffusion test and E-test (AB Biodisk, Sweden). Vancomycin resistant\nenterococci were used for detection of vanA, vanB and vanC genes by PCR. Results\nVancomycin resistant strains of enterococci were isolated from 46 (16.1 %) of the 285\nhospitalized patients and 5 (7.7 %) of the 65 patients living in the community (p < 0.05). The\nmost of highly resistant enterococci to vancomycin (95.2 %) were identified as E. faecium.\nMinimal inhibitory concentrations (MICs) to Vancomycin in all 39 vanA genotypes of E.\nfaecium and two vanA genotypes of E. fecalis were > 256 g/ml. Three vanB genotypes of E.\nfaecium and one vanB genotype of E. faecalis had MICs of 32 g/ml. All six vanC genotypes\nof E. gallinarum had MICs of 8 g/ml. All vanA genotypes of VRE were highly resistant to\nvancomycin, with MICs above 256 g/ml. Three vanB genotypes of VR E. faecium and one\nVR E. fecalis were resistant, with MICs 32 g/ml. vanC genotypes of VR E. gallinarum were\nintermediate resistant to vancomycin with MICs of 8 g/ml. Conclusion The prevalence of\nvancomycin resistant enterococci in R. Macedonia was 2-fold higher in hospitalized than in\noutpatients. vanA genotype was dominant in isolates of E. faecium and it was highly\nassociated with the MIC values above 256 g/ml. Since most of the enterococcal infections\nare endogenous, there is a need for screening the colonization of patient’s intestinal flora with\nVRE at the hospital entry. Identification and genotyping of faecal enterococci together with\ntheir susceptibility testing to vancomycin could be useful marker for the infection control.

Algae biofuels have received attention lately as they can provide a viable alternative to fossil fuels. Algal cells are continuously mixed by a paddle-wheel movement in a large pond, to prevent the settling of algal biomass and increase the productivity. Therefore the fuel cost is directly proportional to the paddle-wheel energy consumption. The three-dimensional simulation is done to investigate the effect of paddle-wheel rotation on the flow field and dead-zone regions of pond. The results are compared with the case of single phase flow with equivalent momentum source term, which has been used by other researcher in order to optimize pond geometry and estimates the power consumption of paddle-wheel. We observe different flow characteristics in comparison of two cases. When using a source term instead of paddlewheel, the dead zone regions of the pond and flow separation at the hairpin bends are overestimated as a flow depth variation due to centrifugal forces cannot be taken in to account. also the depth increase is observed after the paddlewheel, which change the velocity field in entire pond and cannot be modeled by a single phase flow with the source therm.

Tillering of grasses is based on the formation of the basal zone of shortened internodes and initiation of buds of a certain capacity, and it is completed by its transition to the growth, differing by peculiar morphological and biochemical features in its development.

In the following chapters calculations of load parameters of a main pipe saddle beam at a depth of 929 m in the pit no. 2 of the Dukla Mine, Lazy Mine, o.z. of OKD, a.s. are performed. We consider individual profiles as beams on two supports, since for the period of the pit operation it is possible to think that at the point of fixing the profiles into concrete masonry a slight deformation took place.
