Here fourteen morphological characters were selected for the cladistic analysis. Using software Hennig 86, two phylogenetic trees were inferred and the results showed that the subfamily Homalopsinae was divided into two groups. Compared with the molecular phylonenetic tree of Voris et al (2002), the genera Gerarda and Fordonia are sister groups in both studies; both studies also yielded the same monophyletic lineage, which contained three genera (Cerberus + Erpeton + Homalopsis ). However, the position of the genus Cantoria is distinctly different with the study of Voris et a1(2002).展开更多

Peat soil minerals from three peats and swamps across Golestan Province in northern Iran were first characterized by micromorphological studies. Soils were composed mainly of quartz, muscovite, biotite, pyroxene,sericitized Fe-nodules, and iron-rich garnet. In addition,micromorphological results indicated that Galougah Coastal Swamp sections contained some inorganic residue with biological origin including oyster and limpet, which may be related to the swamp's location near Gorgan Gulf.In order to determine mineralogical properties of samples,twelve unknown grains were chosen for elemental concentration map studies. Quartz, garnet, ilmenite, calcite,and pyroxene in Suteh samples; epidote and Fe-nodule in Ghaleh-Ghafeh Peat Swamp; and barite, phyllosilicates,and calcite in Galougah were identified by WDX mapping of Si, Al, Fe, Ca, Mg, C, Ba, S, and Ti. Composition of the oysters' body was also analyzed by WDX for Si, Ca, Fe,and C. The results indicated that most of the minerals in all sections likely formed through weathering, inheriting their composition from the parent rock. This research suggests that merging micromorphology and SEM/WDX image techniques can be useful in confirming the presence of mineral particles in soil science.展开更多

That explains its significance for more efficient functioning of various systems in business world. For that reason, organized societies with developed economies invest in empiric, theoretic, and theoretic-empiric investigations of various sectors and applied dimensions of business ethics. Its epistemological sense reflects to increasing productivity, more successful establishing of the system of hierarchy within an enterprise, appropriate formulating the strategy of management, improving the market reputation, increasing profitability, and strengthening social responsibility. The complexity of modem and successful business is based on a series of social factors which spread in the arch from anthropological, socially-psychological, and cultural characteristics of a human being, to quality characteristics of the global society. That is why the scientific information available to business ethics is synthesized from various scientific perspectives. This paradigm is a starting point of this project which is about the above subject. Its cognitive aim is presented through the description, classification, and explanation of the influence of business ethics to successful functioning of every kind of business institution. As a theoretic investigation which grows from verified scientific information and their critical analysis, it relies on standard, general scientific, basic special and general methods which are characteristic to the applied scientific disciplines. Business ethics has clearly established two key cognitive bases of its investigations: 1) personal value attitude; and 2) interests of a company, groups, and individuals in them. This project is only a small contribution to explaining elementary functions of this applied ethics in business world.展开更多

As always said, that young Gulf inherently consumerist element of first degree because of abundant liquidity and reasonable level of income compared to others of non - Gulf societies. Therefore, this research aims to study and analyze the impact of consumer awareness among the students of the Faculty of Business Administration in consumer protection in terms of the current role and hoped to guide consumption and its relationship to some economic and social characteristics of the consumers. In particular it has been studying the impact of some of the qualifications for heads of Kuwaiti families, their total monthly income and their place of residency inhabited by the expressive factors of consumer awareness in college students as well as their impact on the degree of preference for quality of consumer goods in being a low-price, median-price or expensive-price. In addition, it has been studying the relationship of these social variables noted with the role of government and consumer protection associations through what they are doing to develop laws and policies directed to develop and educate consumers. To achieve these goals, a special questionnaire has been prepared especially for this purpose has been met from a random sample of students from the University of Kuwait. I have been using the appropriate statistical analysis to study these goals. Thus, some of the appropriate suggestions and recommendations are obtained to achieve the objectives of this research.展开更多

Contourlet is a new image sparse representation, which is better than a wavelet for piecewise smooth images with smooth contours. Because of flexible multiresolution, local and directional sensitivity of Contourlet transform, our approach also defines significant-tree in the Contourlet domain. By analyzing the relation of the Contourlet coefficients, we embed the watermarking into all the coefficients of each significant-tree. Then referring to the statistical properties of the coefficients, the masking characteristics of texture are defined for adaptively controlling the embedding strength. Experimental results show that the proposed algorithm is highly robust to various attacks, such as JPEG compression, medium filtering, cropping and rotation. Furthermore, comparisons with a classical method in the wavelet domain prove the validity of the new algorithm.展开更多

One of the reasons might be attributed to the lack in metacognitive abilities. The aim of this study was to compare the metacognitive characteristics between non-major and major students in electric engineering and clarify the difference of metacognitive process between these two groups when solving basic problems of electronic circuit. In the experiment, the solving process was compared between non-major and major students in electric engineering using five basic problems. We found that the scores on prediction of result and confidence of own answer differed significantly between non-major and major students, and inferred that the difference of performance was due to the lack in metacognitive ability, especially the plan and the execution abilities. Both prediction of results and confidence of own answer were also found to play a significant role in effective problem solving as important components (subsystems) of metacognition.展开更多

Particularly, interesting is the fact that the language of science is characterized by the use of figurative language, which appeals to the common knowledge of the world, mainly to explain, clarify, and describe intricate concepts. Metaphors are helpful for lexicalizing new concepts and meanings or extending the meanings of pre-existing words. The analysis of tropes as a means to improve foreign language learners' reading competence is a rather novel teaching practice in ESP (English for Specific Purposes), implemented at the University of Rio Cuarto, Argentina. Therefore, the aim of this paper is to explain the theoretical basis for teaching and developing metaphorical competence in ESP classes as a means of providing an intellectually stimulating alternative approach, and to present some teaching ideas and activities designed to familiarize students with the use of metaphorical language in scientific discourse in order to enhance their reading competence.展开更多

College English has long been in for the college English subject status. However, college English as a multidisciplinary,interdisciplinary research in the field of discipline construction, it seems, are still stay in the linguistics, language knowledge in academiccharacteristics for its stage of development. Reform of basic college English teaching, the teacher is still teaching main body, is the teaching oflanguage knowledge, since teachers play an important role in language teaching, the teacher wants to penetrate cultural knowledge in teachingand we must strengthen their own culture. Under this basis, this paper proposes the novel ideals on the related issues that will be meaningful andinnovative.展开更多

A hands-on practical was developed to simplify detection of enzyme activity of amylase, protease and lipase on starch agar, dry whole milk agar, and trihutyrin agar, respectively. The subjects of the study were 24 senior undergraduates who studied in the Program of General Science, Faculty of Science, Srinakharinwirot University, Bangkok, in three semesters during 2007 - 2008. The basic concepts of enzymes, e.g., substrate specificity, how to detect enzymes and optimal enzyme conditions, were taught before the practical. The first enzyme, protease, was used in the second semester of 2007, and then changed to be lipase and protease in the first and second semesters of 2008, respectively. Ten open-ended questions were used to assess students in all semesters. In agreement with the constructivist learning model, it was demonstrated that students had learning retention and applied their prior knowledge to other enzyme experiments.展开更多

The criticism pointed out the way for the solution of the ecological problems and showed the seeds of ecological civilization. The paper reveals the ontology about ecological civilization and generation and elimination of crisis through analyzing the Marxist thought of ecological civilization in manuscripts. The paper believes that Marxist thought of ecological civilization may enlighten us to carry forward and develop it with guidance, sense and theory. We sincerely expect that the thought of ecological civilization will be rooted in the hearts of the people deeply by means of the rise of "green" concept and the education of ecological ethics. The paper has important theoretical and practical value on deeply understanding the relationship between human and nature with scientific development angle of view, conquering the ecological crisis of globalization scientifically and building and developing ecological civilization of Chinese characteristic socialism energetically.展开更多

The development of medical virology in Malaysia has its beginning in the Institute for Medical Research(IMR) ,following the establishment of the Division of Medical Zoology and Virus Research in the institute on 23 March 1953. The second institution in the country to establish diagnostic and research work in medical virology was Department of Medical Microbiology,Faculty of Medicine,University Malaya. This was followed by University Kebangsaan Malaysia,University Sains Malaysia and University of Sarawak Malaysia. The National Public Health Laboratory(NPHL) is the latest institution to establish a laboratory in 2003 for virus isolation and services to support country surveillance and outbreak investigation of infectious diseases due to viruses. In the field of medical virology,Malaysia contributed substantially in the areas of virus diagnostic services,development and research ranging from survey and documentation on the existence and prevalence of viruses causing diseases in Malaysia,clinical presentation and epidemiological features of virus diseases,evaluation of new diagnostic tests to pathogenesis of viral diseases. Malaysia contributed to the discoveries of at least 12 new viruses in the world. ASEAN plus Three(China,Japan,Republic of Korea) Emerging Infectious Programme was established to overcome the challenges and impact of emerging and re-emerging infectious diseases in this region. Malaysia as the co-ordinator of the laboratory component of the programme,contributed to strengthen the regional laboratory capability,capacity,laboratory-based surveillance and networking. The future of medical virology in Malaysia in terms of integration of diagnostic,reference and research to support the country's need will be enhanced and strengthened with the on-going development of the National Centre for Disease Control and Prevention(CDC Malaysia) which also incorporates a futuristic Special Diagnostic and Reference Laboratory.展开更多

According to China's national conditions and the characteristics of the cultures, improve the research methodology of the national musicology, so that the national musicology can have the Chinese characteristics. The national musicology is an independent basic discipline in the university education. In China, the music education and research work in colleges and universities has an important role in the inheritance and development of the national music. In this paper, combined with the present situations of the music education in colleges and universities, from the perspectives of the education and the research, the author expounds the ideas of the development trends of the national musicology in the music education in colleges and universities.展开更多

The embrace of storytelling in the digital realm by these young minds reflects the interplay of traditional culture, western modernism, and changes brought about by media industries. These women have adopted and used new media as a vehicle to maneuver their interesting and fresh ideas and have seen the rectilinear screen of a computer as an exit through which to come out and say something to the masses. The thinking methodology has culminated in pragmatic and dynamic visuals in order to celebrate, inform, and create awareness about the issues that they see in the region and among the people. With this freedom of expression, they are creating a new visual culture and transforming themselves into a meaningful workforce. With emerging technological tools, they blend intuitive, pragmatic, emotional, and contextual imagination with a highly-sophisticated production pipeline in order to incorporate the challenges of synthesizing "dialect" and "codes" that have traditionally been segregated in the culture. Their work is an amalgamation of arts/design, animation, life footage, and meaningful communication. With cyclical evaluation, they entwine the two elements, creativity, and technicality with massive exposure of Digital Assists Management (DAM). This paper explains how current technological tools and contextualized teaching instructions foster meaningful content with the elicitation and mergence of Arab anthropological characteristics.展开更多
文摘The morphological phylogeny of the water snake subfamily Homalopsinae, containing 10 genera, of which seven are monotypic, was not reported up until now. Here fourteen morphological characters were selected for the cladistic analysis. Using software Hennig 86, two phylogenetic trees were inferred and the results showed that the subfamily Homalopsinae was divided into two groups. Compared with the molecular phylonenetic tree of Voris et al (2002), the genera Gerarda and Fordonia are sister groups in both studies; both studies also yielded the same monophyletic lineage, which contained three genera (Cerberus + Erpeton + Homalopsis ). However, the position of the genus Cantoria is distinctly different with the study of Voris et a1(2002).
