    The wetlands of the coastal Louisiana have been disappearing at an alarming rate. The rate was further accelerated during the Hurricane Katrina. Hurricane Katrina converted a large area of wetland into open water by bulk removal of vegetation, flooding, and killing of plants through the salt water inundation. The aim of this study was to quantify wetland loss rates in a high salinity wetland of St. Bernard Parish, Louisiana before and after Hurricane Katrina made landfall. Change-detection-mapping and analysis, using Landsat TM images, was used for generating the change matrices. Images from 1990 and 2010 were analyzed to estimate total wetland loss and the wetland loss contributed by Hurricane Katrina over the 20-year period. The analysis revealed that wetland loss in the study area during Hurricane Katrina accounted for over half (65%) of the total land lost over a 20-year period (1990 to 2010). The annual net loss of wetland to water during 2003-2004, 2004-2005 and 2005-2006 were estimated to be 10.82 km2, 15.42 km2 and 36.06 km2 respectively, which is 26.45 %, 24.80% and 48.76% of total changes in four years (2003-2006). Vegetation disturbances were mapped using Normalized Difference Vegetation Index (NDVI)

    New Englishes have emerged all over the world and are seen as developing from what can be called the established native speaker variety. Malaysian English is a non-native variety distinct from the Standard British English. The consolidation of this variety in its present form or its continuity evolving into a form even further from its roots, depends on the attitudes of its speech community. Malaysian English has emerged in a systematic and consistent manner both in spoken and written forms. The results of the survey indicate that there is tolerance for Malaysian English both in the spoken and written mode

    Aim: The objective of the current study was to assess the effectiveness of pranayama on educational stress among adolescents. Methods: In a quasi-experimental one-group pretest and posttest design, adolescents between the ages of 12 and 18 were selected using a purposive sampling technique. The self-structured demographic variables and the Educational Stress Scale for Adolescents (ESSA) (Sun J, 2011) were used to assess the pre and post-test levels of educational stress. A structured interview schedule was used to assess the adolescents' level of educational stress. Following the pre-test, samples were given daily pranayama training in a calm and quiet environment. The Pranayama procedure took about 30 minutes to complete. A post-test was performed three months after the intervention. Results: Among the 95 adolescents who participated in the study, the pre-test stress levels were mild (15.8%), moderate (45.3%), and severe (38.9%). The same was reduced in the posttest, with mild being 77.8% and moderate being 22.1%. The severe stress was null. There was a significant difference in educational stress levels before and after Pranayama training (t=27.707; p<.0001). The adolescents' mean score of educational stress before and after Pranayama was 56.7 and 31.4, respectively. The mean reduction was 25.4±8.9. There was a significant association between age, gender, grades, and internet usage; 6.0, 7.3, 11.8 and 13.866, respectively, at P>0.05. The results discovered that pre-educational stress was decreased after Pranayama training. Conclusion: Educational stress is inevitable for school-age adolescents in today's highly competitive world. In accordance with the study findings, Pranayama practice reduces stress, as evidenced by a significant reduction in educational stress.

    AbstractBackgroundThe tuberculosis and infections caused by nontuberculous mycobacterial (NTM) species are increasing in patients presented with respiratory illness, and it is crucial to document the epidemiology of these infections.ObjectivesTo study the mycobacterial species and in vitro drug susceptibility trends of Mycobacterium tuberculosis found in the respiratory specimens.Materials and methodsA prospective descriptive study from July 2009 to December 2012. The BACTEC MGIT system tubes with growth were used in the study. GenoType Mycobacterium (Hain Diagnostika, Nehren, Germany) assays were used to identify the mycobacteria. The drug susceptibility testing was performed by the MGIT 960 system.ResultsA total of 1745 MGIT 960 system positive tubes were included. M. tuberculosis complex (MTC) constituted 67.45% of the yield isolated, 30.83% were nontuberculous mycobacterial species, 0.17% were Mycobacterium bovis BCG and 1.55% were not interpretable to species levels. Mycobacterium fortuitum (45.71%), Mycobacterium abscessus (26.21%) and Mycobacterium intracellulare (10.41%) were major NTM identified. The drug susceptibility study showed that 6.88% (81/1177) of MTC were drug-resistant TB, 56 isolates were resistant to one of the first-line anti-TB drugs, 25 isolates were found to be resistant to 2 or more first-line anti-TB drugs, of which 19 (20.46%) were MDR-TB and one of the isolates in the year 2011 was confirmed XDR-TB.ConclusionM. tuberculosis, M. fortuitum, M. abscessus and M. intracellulare were major mycobacterial species detected in the respiratory samples. The drug susceptibility testing showed that the majority of MTC were sensitive to first-line anti-TB drugs

    Heart disorder is one of the complicated sicknesses and globally many human beings suffered from this disorder. On time and green identity of coronary heart disorder a key function in fitness care especially withinside the area of cardiology. The utility of disorder prediction the usage of system gaining knowledge of withinside the scientific analysis area is growing successively. This may be contributed mainly to the development withinside the type and pinpointing structures utilized in disorder identity and reputation structures utilized in disorder analysis that's capable of offer records that aids health workers in early identity of deadly sicknesses and therefore, elevating the survival price of sufferers importantly. Applying distinctive styles of algorithms, every with its personal benefit on 3 separate databases of disorder (Heart) to be had in UCI repository for disorder prognosis. The results regarding the identification of diseases using machine learning algorithm has strengthen the concept of the applying of machine learning in early detection of diseases, so that the disease can be diagnosed in the early stage itself and then it can be treated as earlier.So that the survival prices of the sufferers may be increased.&nbsp

    Candida auris: A Mini Review on Epidemiology in Healthcare Facilities in Asia

    No full text
    Candida auris, a newly emerging healthcare-associated yeast pathogen from the Metschnikowiaceae family, was first described in the ear canal of an elderly Japanese patient in 2009. The yeast is one of the causative agents of candidemia, which has been linked with nosocomial outbreaks and high mortality rates in healthcare facilities worldwide. Since its first isolation, the occurrence of C. auris in six continents has becomes a grave concern for the healthcare professionals and scientific community. Recent reports showed the identification of five geographically distinct clades and high rates of antifungal resistance associated with C. auris. Till date, there are no effective treatment options, and standardized measures for prevention and control of C. auris infection in healthcare facilities. This leads to frequent therapeutic failures and complicates the eradication of C. auris infection in healthcare facilities. Thus, this review focuses on the recent understanding of the epidemiology, risk factors, diagnosis, transmission and prevention and control strategies of C. auris infection in healthcare facilities in Asia
