Abdul Mannan  S. Mustafa  Md. Safay Zaffar Bharati 《International Information and Library Review》2009,41(2):71-78

The study is focused on finding out the level of use of on-line databases by faculty members and research scholars of the Jawaharlal Nehru University (JNU) and Jamia Millia Islamia (JMI), Delhi (India). Both are Central Universities and are funded by the University Grants Commission (UGC). A well-structured questionnaire was administered to faculty members and research scholars of the JNU and JMI to collect data regarding the use of on-line database. The survey reveals that all of the faculty members and research scholars are aware of the availability of on-line databases and largely use them for reference purposes in their research work and studies. The degree of usefulness and utilization of on-line databases is high among the universities' faculty members and research scholars. The survey further reveals that the respondents from both universities are aware of the search options for accessing on-line databases. It is also found that a large number of respondents of JNU and JMI are using field searching and Boolean operators to access information from on-line databases.  相似文献

Gender and behavioural differences in Kuwait primary schools     

Yousuf Almurtaji  John Everatt  Nasser S. Almenaye  Ahmad S. Alazemi  Dalal Abdul Hadi Alradaan 《Emotional and Behavioural Difficulties》2018,23(2):141-153

Previous studies have found significant differences between the classroom behaviour of boys and girls. Most are within a single broad cultural context and little work has been done within an Arabic/Kuwaiti one. The main aim was to investigate the differences in behaviour between boys and girls in Kuwait primary schools. Data were collected that provided comparisons across questionnaires between parent and teacher returns for over 430 students. Separate teacher observations of students (n = 671) and classroom researcher observations were also obtained. Significant differences were found across the scales, indicating higher levels of externalising misbehaviour among boys than girls. A comparison with three studies conducted in other cultural contexts using the same strengths and difficulties instrument as used in this study found similarities and differences in results between the behaviour of boys and girls.  相似文献   

HealthCyberMap: a semantic visual browser of medical Internet resources based on clinical codes and the human body metaphor     

Kamel Boulos MN  Roudsari AV  Carso N ER 《Health information and libraries journal》2002,19(4):189-200

OBJECTIVES: HealthCyberMap (HCM-http://healthcybermap.semanticweb.org) is a web-based service for healthcare professionals and librarians, patients and the public in general that aims at mapping parts of the health information resources in cyberspace in novel ways to improve their retrieval and navigation. METHODS AND SERVICE DESCRIPTION: HCM adopts a clinical metadata framework built upon a clinical coding ontology for the semantic indexing, classification and browsing of Internet health information resources. A resource metadata base holds information about selected resources. HCM then uses GIS (Geographic Information Systems) spatialization methods to generate interactive navigational cybermaps from the metadata base. These visual cybermaps are based on familiar medical metaphors. CONCLUSIONS: HCM cybermaps can be considered as semantically spatialized, ontology-based browsing views of the underlying resource metadata base. Using a clinical coding scheme as a metric for spatialization ('semantic distance') is unique to HCM and is very much suited for the semantic categorization and navigation of Internet health information resources. Clinical codes ensure reliable and unambiguous topical indexing of these resources. HCM also introduces a useful form of cyberspatial analysis for the detection of topical coverage gaps in the resource metadata base using choropleth (shaded) maps of human body systems.  相似文献

The ability of triadimefon(TDM),a triazolic fungicide,to alter the biochemical constituents and thereby minimizing the days required for sprouting in white yam(Dioscorea rotundata Poir.) tubers during storage under(30±2) °C in the dark,was studied.TDM at 20 mg/L was given to tubers by dipping the tubers in treatment solution containing 20 mg/L TDM on 10,25 and 40 d after storage(DAS).Starch,sugars,protein,amino acid contents as well as protease and α-amylase activities were estimated on 15,30 and 45 DAS from two physiological regions viz.,apical and basal regions of the tubers.In normal conditions(control) sprouting occurred on 70 to 80 DAS.The starch content decreased,while protein,amino acid,sugar contents and protease and α-amylase activities were increased due to TDM treatment and led to early sprouting.  相似文献   

Overexpression of the phytochrome B gene from Arabidopsis thaliana increases plant growth and yield of cotton (Gossypium hirsutum)     

Rao AQ  Irfan M  Saleem Z  Nasir IA  Riazuddin S  Husnain T 《Journal of Zhejiang University. Science. B》2011,12(4):326-334

The phytochrome B (PHYB) gene of Arabidopsis thaliana was introduced into cotton through Agrobacterium tumefaciens. Integration and expression of PHYB gene in cotton plants were confirmed by molecular evidence. Messenger RNA (mRNA) expression in one of the transgenic lines, QCC11, was much higher than those of control and other transgenic lines. Transgenic cotton plants showed more than a two-fold increase in photosynthetic rate and more than a four-fold increase in transpiration rate and stomatal conductance. The increase in photosynthetic rate led to a 46% increase in relative growth rate and an 18% increase in net assimilation rate. Data recorded up to two generations, both in the greenhouse and in the field, revealed that overexpression of Arabidopsis thaliana PHYB gene in transgenic cotton plants resulted in an increase in the production of cotton by improving the cotton plant growth, with 35% more yield. Moreover, the presence of the Arabidopsis thaliana PHYB gene caused pleiotropic effects like semi-dwarfism, decrease in apical dominance, and increase in boll size.  相似文献   

Is saying ‘sorry’ enough? examining the effects of apology typologies by organizations on consumer responses     

May O. Lwin  Jun-Qi Loh  Marilyn Hui-Ying Peh  Sarah Ann Rodriguez  Nur Hanisah Binte Zelani 《亚洲交流杂志》2017,27(1):49-64

Apology has been found to be the most effective strategy in times of crises. However, there is a dearth of research on the kinds of apology used and how primary stakeholders, in particular consumers, received them. This study aims to examine consumer responses to the types of apologies offered post crises against the levels of attribution of responsibility. We also assess the potential mediating role of ethical concerns by developing the Perception-Behavioral Model of Crisis Response. An experiment was conducted to ascertain consumers’ impression of the organization post-apology. The results showed that the attribution of crisis responsibility significantly influences complaining, withholding and negative word-of-mouth behaviors. However, a very high degree of apology issued by the organization does not necessarily translate to reduced negative responses from consumers in light of the large attribution of responsibility. Finally, the Perception-Behavioral Model of Crisis Response suggests that ethical concerns can mediate negative behavioral intentions from consumers.  相似文献

Endophytes from medicinal plants and their potential for producing indole acetic acid,improving seed germination and mitigating oxidative stress     

Abdul Latif Khan  Syed Abdullah Gilani  Muhammad Waqas  Khadija Al-Hosni  Salima Al-Khiziri  Yoon-Ha Kim  Liaqat Ali  Sang-Mo Kang  Sajjad Asaf  Raheem Shahzad  Javid Hussain  In-Jung Lee  Ahmed Al-Harrasi 《Journal of Zhejiang University. Science. B》2017,18(2):125-137

Medicinal plants have been used by marginal communities to treat various ailments. However, the potential of endophytes within these bio-prospective medicinal plants remains unknown. The present study elucidates the endophytic diversity of medicinal plants (Caralluma acutangula, Rhazya stricta, and Moringa peregrina) and the endophyte role in seed growth and oxidative stress. Various organs of medicinal plants yielded ten endophytes, which were identified as Phoma sp. (6 isolates), Alternaria sp. (2), Bipolaris sp. (1), and Cladosporium sp. (1) based on 18S rDNA sequencing and phylogenetic analysis. The culture filtrates (CFs; 25%, 50%, and 100% concentrations) from these endophytes were tested against the growth of normal and dwarf mutant rice lines. Endophytic CF exhibited dose-dependent growth stimulation and suppression effects. CF (100%) of Phoma sp. significantly increased rice seed germination and growth compared to controls and other endophytes. This growth-promoting effect was due to the presence of indole acetic acid in endophytic CF. The gas chromatography/mass spectrometry (GC/MS) analysis showed the highest indole acetic acid content ((54.31±0.21) μmol/L) in Bipolaris sp. In addition, the isolate of Bipolaris sp. exhibited significantly higher radical scavenging and anti-lipid peroxidation activity than the other isolates. Bipolaris sp. and Phoma sp. also exhibited significantly higher flavonoid and phenolic contents. The medicinal plants exhibited the presence of bio-prospective endophytic strains, which could be used for the improvement of crop growth and the mitigation of oxidative stresses.  相似文献   

Assessment of the phase synchronization effect in modal testing during operation     

Zhi Chao Ong  Hong Cheet Lim  Shin Yee Khoo  Zubaidah Ismail  Keen Kuan Kong  Abdul Ghaffar Abdul Rahman 《浙江大学学报(A卷英文版)》2017,18(2):92-105

The impact-synchronous modal analysis (ISMA), which uses impact-synchronous time averaging (ISTA), allows modal testing to be performed during operation. ISTA is effective in filtering out the non-synchronous cyclic load component, its harmonics, and noises. However, it was found that at operating speeds that coincide with the natural modes, ISMA would require a high number of impacts to determine the dynamic characteristics of the system. This finding has subsequently reduced the effectiveness and practicality of ISMA. Preservation of signatures during ISTA depends on the consistency of their phase angles on every time block but not necessarily on their frequencies. Thus, the effect of phase angles with respect to impact is seen to be a very important parameter when performing ISMA on structures with dominant periodic responses due to cyclic load and ambient excitation. The responses from unaccounted forces that contain even the same frequency as that contained in the response due to impact are diminished with the least number of impacts when the phase of the periodic responses is not consistent with the impact signature for every impact applied. The assessment showed that a small number of averages are sufficient to eliminate the non-synchronous components with 98.48% improvement on simulation and 95.22% improvement on experimental modal testing when the phase angles with respect to impact are not consistent for every impact applied.  相似文献
