Genomic DNA from a clinical isolate ofMycobacterium avium-intracellulare complex was purified and cloned in PBR 322 at the tetracycline resistance site using Bam HI restriction enzyme. A 16 kb cloned
fragment was purified, radiolabeled and used as a probe. Genomic DNA isolated from nineteen MAC strains, threeM. tuberculosis strains and oneM. kansasii strain were digested with Eco RI restriction enzyme, Southern blotted and hybridized with the 16 kb cloned and labeled fragment.
Twelve MAC strains showed positive hybridization although five strains gave faint signals. Positive hybridization was noted
in two out of the threeM. tuberculosis strains, possibly due to shared DNA homology. No signal was received from the singleM. kansasii strain used in this study. 相似文献

Recent years it has an explosive development of IT technologies. However, the problem of natural integration of modern technologies in teaching and learning mathematics is far from its final solution. In teaching mathematics at universities, these capabilities either are ignored or have extremely limited applications. In our study, we consider animation as one of the tools that could increase students' motivation, curiosity and understanding. In order to evaluate the perception about using animation in the study of calculus, a brief survey was conducted in University Utara Malaysia (UUM). The survey consisted of 17 lecturers and 25 students from UUM. The survey also conducted in UPM (University Putra Malaysia) and UniKL (University Kuala Lumpur), which comprised of 82 students and 49 students respectively. At the same time, we are interested in whether or not the perception of students differs by factors like gender, age group, entry qualification, program of study and previous grades. This survey was conducted in UPM comprised of 160 students. In this paper, we describe our data and report our findings, make a comparison between students' perception in UPM, UUM and UniKL. Further a comparison is also made regarding perception of UniKL students from two different programmes of study. To evaluate the performance of students, a simple comparative experiment between Computer Aided Learning Method (CALM) and the Traditional Learning Method (TLM) conducted in UUM and UPM and we report our preliminary findings in this paper. 相似文献

Fused deposition modelling (FDM) is one of rapid prototyping (RP) technologies which uses an additive fabrication approach.Each commercially available FDM model has different types of process parameters for different applications.Some of the desired parts require excellent surface finish as well as good tolerance.The most common parameters requiring setup are the raster angle,tool path,slice thickness,build orientation,and deposition speed.The purpose of this paper is to discuss the process parameters of FDM Prodigy Plus (Stratasys,Inc.,Eden Prairie,MN,USA).Various selected parameters were tested and the optimum condition was proposed.The quality of the parts produced was accessed in terms of dimensional accuracy and surface finish.The optimum parameters obtained were then applied in the fabrication of the master pattern prior to silicone rubber moulding (SRM).These parameters would reduce the post processing time.The dimensional accuracy and surface roughness were analyzed using coordinate measuring machine (CMM) and surface roughness tester,respectively.Based on this study,the recommended parameters will improve the quality of the FDM parts produced in terms of dimensional accuracy and surface roughness for the application of SRM. 相似文献

The pun is a tricky use of a word or phrase which has very different meanings that are closely interrelated, or of words with the same sound but different meanings. The Pun is a term with a dual meaning: “close” using obvious reference, and “far” using obscure reference. The hidden is usually meant. The close meaning is the sooner that comes to the listener’s mind. However, the speaker targets at the far one yet use the close to hide it. Translating the Quran text always raises several serious challenges in translation; these challenges are due to the different translations of puns and the misinterpretations between the intended meanings of a pun with their basic concepts, which could result in a certain amount of ambiguity. The study examines the Quranic corpus and its three versions of English translations. The study utilizes the typology of Delabastita?s for horizontal puns, Nida’s techniques of dynamic and formal equivalent and Newmark’s translation methods. This research attempts to investigate the semantic meaning of puns in the Quran translation and to define the translation techniques applied in translating the Quranic puns from Arabic into English. 相似文献

The use of the physical environment as a three-dimensional (3-D) textbook is not a common practice in educational facilities design. Previous researches documented that little progress has been made to incorporate environmental education (EE) into architecture, especially among the conventional designers who are often constrained by the budget and building area requirements. This article presents an exploratory project to develop a prototype for the 3-D textbook. The author does not formulate ideas and concept based on the pre-determined specs in a design brief. Instead, the design solution evolved through a qualitative case study conducted at the Green School in Bali, Indonesia. Data were collected through a series of interviews and on-site observations. The qualitative findings uncovered four design features for the 3-D textbook. A prototype was subsequently developed using the design features as a blueprint. The prototype serves as a testing ground for new ideas as well as a platform to promote awareness and acceptance of the 3-D textbook among the practitioners. Consequently, this article attempted a significant proposition to bring together architecture and EE, thus potentially contributing to a field of knowledge that embraces design and education. 相似文献

This study focused, for the first time, on the effect of ultrasonic features on the extraction efficiency of secondary metabolites in mustard seed cake(MSC). The nematostatic potential of sonicated seed cake was examined against the second-stage juveniles(J2 s) of root-knot nematode, Meloidogyne javanica. The results show that a 35 ppm(parts per million) concentration of a sonicated extract(SE) sample of MSC caused 65% J2 s mortality at 18 h exposure period in vitro. It also significantly suppressed the root-knot index(RKI=0.94) in tomato roots. The lethal concentration values for SE were 51.76, 29.79, and 13.34 ppm,respectively, at 6, 12, and 18 h of the exposure period, and the lethal concentration values for the non-sonicated extract(NSE)sample were 116.95, 76.38, and 55.59 ppm, respectively, at similar exposure time. Sinapine and gluconapin were identified as the major compounds in ultrasonic-assisted MSC. Because of the high extraction efficiency of metabolites in the SE, all treatments of SE were shown to be antagonistic to J2 s. Thus, this study of ultrasonication activity-based profiling of MSC may help generate target-based compounds at a scale relevant to the control of disease caused by nematodes in economic crops. 相似文献

The complexity of science teaching requires science teachers to encounter a range of tasks. Some tasks are perceived as stressful while others are not. This study aims to investigate the extent to which different teaching situations lead to different stress levels. It also aims to identify the easiest and most difficult conditions to be regarded as stressful conditions by science teachers. An occupational stress inventory of 25 items developed by Okebukola (1988) validation of the occupational stress inventory for science teachers. Science Teacher, was used to measure the science teachers’ stress level in science teaching. A four point Likert scale ranging from 1 – ‘no stress at all’ to 4 – ‘extreme stress’ was used. Fifty-eight Malaysian secondary science teachers participated in the survey in which six volunteered to participate in the interview study. The data was then analyzed using the Rasch model to measure the level of stress caused by different kinds of stressful conditions. Even though ‘overloaded science syllabus’ was identified to be the basis of multiple stressful conditions, it was, however, difficult for the respondents to regard it as a stressful condition. On the other hand, the respondents found that ‘having to teach difficult science topics’ is easiest to be regarded as a stressful condition. It was shown that even though ‘overloaded science syllabus’ is the starting point for stress caused by multiple conditions, due to the availability of coping strategies which can be employed by the respondents, the stressor is minor in causing stress among teachers. On the other hand, when teachers lack the availability of coping strategies dealing with teaching difficult science topics, they easily feel stressful. One of the main recommendations to overcome stressful conditions is to provide the science teachers ‘topic specific pedagogy’ during in-service training. 相似文献
