This study aimed at comparing students‟ ability in writing descriptive text withblogtechnique and without blog. This study is used to answer the questions: Is thereany significant difference in the achievement between the students who wrotedescriptive text with blogtechnique and the students who wrote descriptive text withoutblog? And how well the students write descriptive text after being taught by using blog.Quantitative method was used in analyzing the gathered data. The basic outline showedthat in the writing skill, the second year students in the first semester of Junior HighSchool are supposed to write a descriptive text, so the data weredescriptive textswritten by two classes of the second year students of MTs Brangsong Kendal as thesample. One of them was the experimental group and the other one was the controlgroup. The result of the study shows that Blog technique applied in writingdescriptiontexts of VIIIgrade of MTs Brangsong, Kendal, actually gave contribution in improvingthe students‟ skill in writing descriptive texts. This technique could be an effectivemethod. It is proper since there was a significant difference between the control groupand the experimental group when the study was conducted. Based on the statisticalanalysis, it could be seen that the students‟ in the experimental group was improvinghigher than the control group. The mean of the experimental group was higher (from71.81to 80.11) than the control group (from 71.72 to 74.61). The t-value for two meansof post-test was 4.170; meanwhile the critical value at α = 5% was 1.67. Since the tvaluewas in the Ho rejection area, it was concluded that there is a significantdifference in the achievement between the students in control group who were not giventhe treatment and the experimental group who were given the treatment (Blogtechnique). By using this technique in the experimental class, the class situation wasvery enjoyable, the students freely communicated to each other to share their ideas.The writer had observed that the writing descriptive texts scores of the experimentalclass were higher than those of the students who wrote descriptive text without Blog.Keywords: Blog, Descriptive Text, WritingSkill

AbstractWe present an investigation of halo coronal mass ejections (HCMEs) kinematics and other facts about the HCMEs. The study of HCMEs is very important because HCMEs are regarded as the main causes of heliospheric and geomagnetic disturbances. In this study, we have investigated 313 HCMEs observed during 1996-2012 by LASCO, coronal holes, and solar flares. We find that HCMEs are of two types: accelerated HCMEs and decelerated HCMEs. The mean space speed of HCMEs is 1283 km/s while the mean speed of decelerated HCMEs and accelerated HCMEs is 1349 km/s and 1174 km/s, respectively. The investigation shows that 1 (0.3%) HCME was associated with class A SXR, 14 (4.7%) HCMEs were associated with class B SXR-flares, 87 (29.4%) HCMEs were associated with class C SXR-flares, 125 (42.2%) HCMEs were associated with class M SXR-flares and 69 (23.3%) HCMEs were associated with class X SXR-flares. The speed of HCMEs increases with the importance of solar SXR-flares. The various results obtained in the present analysis are discussed in the light of the existing scenario of heliospheric physics.

ABSTRACT Significant interest in studying the lipooligosaccharide (LOS) of Campylobacter jejuni has stemmed from its potential role in postinfection paralytic disorders. In this study we present the results of PCR screening of five LOS locus classes (A, B, C, D, and E) for a collection of 116 C. jejuni isolates from chicken meat (n = 76) and sporadic human cases of diarrhea (n = 40). We correlated LOS classes with clonal complexes (CC) assigned by multilocus sequence typing (MLST). Finally, we evaluated the invasion potential of a panel of 52 of these C. jejuni isolates for Caco-2 cells. PCR screening showed that 87.1% (101/116) of isolates could be assigned to LOS class A, B, C, D, or E. Concordance between LOS classes and certain MLST CC was revealed. The majority (85.7% [24/28]) of C. jejuni isolates grouped in CC-21 were shown to express LOS locus class C. The invasion potential of C. jejuni isolates possessing sialylated LOS (n = 29; classes A, B, and C) for Caco-2 cells was significantly higher (P < 0.0001) than that of C. jejuni isolates with nonsialylated LOS (n = 23; classes D and E). There was no significant difference in invasiveness between chicken meat and human isolates. However, C. jejuni isolates assigned to CC-206 (correlated with LOS class B) or CC-21 (correlated with LOS class C) showed statistically significantly higher levels of invasion than isolates from other CC. Correlation between LOS classes and CC was further confirmed by pulsed-field gel electrophoresis. The present study reveals a correlation between genotypic diversity and LOS locus classes of C. jejuni. We showed that simple PCR screening for C. jejuni LOS classes could reliably predict certain MLST CC and add to the interpretation of molecular-typing results. Our study corroborates that sialylation of LOS is advantageous for C. jejuni fitness and virulence in different hosts. The modulation of cell surface carbohydrate structure could enhance the ability of C. jejuni to adapt to or survive in a host.

Study Objectives: To determine the frequency of cirrhotic cardiomyopathy in patients with liver cirrhosis and to compare it across varying grades of cirrhosis on Child Turcotte Pugh classification. Study Design and Settings: It was a descriptive cross-sectional study carried at Department of Medicine, Lahore General Hospital Lahore over 1 year from Jan 2018 to Dec 2018. Patients and Methods: The present research involved 100 male and female patients aged between 16-70 years having liver cirrhosis diagnosed at least 6 months ago. These patients underwent echocardiographic screening of cardiomyopathy which was diagnosed by the presence of diastolic dysfunction (i.e. increased E/A ratio>1). An informed written consent was obtained from every patient. Results of the Study: There was a male predominance (M:F, 1.6:1) among cirrhotic patients with a mean age of 51.9±9.8 years. The mean BMI was 26.5±3.7 Kg/m2 while the mean duration of cirrhosis was 22.0±10.9 months. Majority (49.0%) of the patients belonged to CTP Class C followed by Class-B (39.0%) and Class-A (12.0%). Cirrhotic cardiomyopathy was observed in 41.0% patients with cirrhosis. There was statistically insignificant difference in the observed frequency of cirrhotic cardiomyopathy among various subgroups of cirrhotic patients depending upon patient’s age (p-value=0.928), gender (p-value=0.997), BMI (p-value=0.983) and duration of disease (p-value=0.782). However, it increased considerably with worsening of disease on CTP Classification; Class-A vs. Class-B vs. Class-C (8.3% vs. 35.9% vs. 53.1%; p-value=0.013). Conclusion: Cirrhotic cardiomyopathy was observed in a substantial proportion of cirrhotic patients and was more frequent in patients with more severe disease which warrants routine echocardiographic screening of cirrhotic patients so that timely recognition and anticipated treatment of this complication may improve the case outcome in future medical practice.

Several factors have been attributed to learners’ underachievement in postgraduate programmes. Two of such factors are gender and entry background of postgraduate distance learners which previous studies have identified in isolation of one another. No previous studies have been reported to have investigated a combination of gender and entry background differences in educational technology. The present study, therefore, investigated the influence of gender and entry background of postgraduate distance learners’ achievement in educational technology. The ex-post facto research design was adopted. Three hundred and twenty-three postgraduate distance learners who registered and sat for examinations of Master of Education in Educational Technology of National Open University of Nigeria, during the first semester of 2019_1 of 2018/2019 academic session were purposively selected from 74 study centres. The participants were made up of 215 males and 108 females. Three null hypotheses were formulated to guide the study and tested at .05 level of significance. The results of participants in 2019_1 first semester were analysed using t-test and analysis of variance (ANOVA). There was a significant difference in the mean achievement scores of male and female postgraduate distance learners in educational technology in favour of male distance learners while no significant difference was established in respect of postgraduate distance learners’ entry background. The implications of this study are that gender difference is a factor of prediction to academic achievement in educational technology but entry background does not influence postgraduate distance learners’ achievement in courses. Recommendations were made among others that there is need to create co-operative learning activities sensitive to preferences of female distance learners.

This thesis is purposed at proving the effectiveness of cartoon videos in teaching speaking to the Eighth Grade Students of SMPN 2 Rantau Kalimantan Selatan in academic year of 2013/2014, and showing that there is a significant difference in speaking ability between the students who were taught by using cartoon videos and those who were taught by using conventional method. This study is an experimental research. The population of this study was the eighth grade students of SMPN 2 Rantau Kalimantan Selatan in academic year of 2013/2014 which consisted of seven classes. The total number of population was 158. There were two classes taken as the sample, Class VIII B serving as control class were taught by using conventional method, while class VIII F as the experimental class were taught by using cartoon videos. Class VIII B consisted of 22 students and class VIII F consisted of 22 students. Both classes were given the pre-test at the beginning and the post-test at the end after the treatment. The data were collected by using speaking test. The data were analyzed by using t-test computation, descriptive analysis, and inferential analysis. The research findings show that there is a significant difference in students’ speaking ability between the experimental group taught by using cartoon videos and those who were taught by using conventional method. The result of the pre-test shows that both groups are poor, while the post-test result shows that the experiment group is better than the control one. The mean score of the experimental class in pre-test was 42.50 and that of control class was 42.73. The mean score in post-test of the experimental class was 75.68 and that of the control class was 57.50. It can be seen that the mean score of the experimental class was higher than that of control class in post-test. Furthermore, based on the hypothesis testing, it could be seen that the value of -t obtained (-5.245) < - t table (-2.018), at the significant level 5%. This implied that there is a significant difference of students’ speaking ability between the students who were taught by using cartoon videos and those who were taught by using conventional method.
