Experiments showed, without much theoretical guidance, that InAs/GaAs quantum dots (QDs) may be tuned to such wavelengths by adjusting the In fraction in an InxGa 1-xAs strain-reducing capping layer. In this paper, systematic multimillion-atom electronic structure calculations explain, qualitatively and quantitatively, for the first time, available experimental data. The nanoelectronic modeling NEMO 3-D simulations treat strain in a 15-million-atom ...

Yahaya (2017) The usability traits of theses and dissertations as sources of information to agriculture students, COLLNET Journal of Scientometrics and Information Management, 11:1, 119-131, The study was carried out on 124 students using cross-sectional survey. Questionnaire was used to determine why agricultural students at different levels of study use thesis and dissertation as a source of information. The study shows that thesis and dissertation is considered and used as a source of information by Bachelor of Agriculture students and their Masters of Agriculture counterpart only. There was a positive relationship between students' level of study and usability traits of thesis and dissertation, whereas, no relationship was observed between area of specialization and usability traits of thesis and dissertation. Use of thesis and dissertation was high among animal scientist when compared with other areas of specialization. Thesis and dissertation was mostly used occasionally as a reference material, more peculiar to students during their terminal stage of study. It was recommended that use of thesis and dissertation should be fostered when students are halfway into the university.

The old and new paradigms of librarianship were cited to reflect the roles played by university libraries of this contemporary 21 st century. The paradigm change role shows that university library users can be better served from the comfort of their destination. Cite This Article As: Usman MK (2015).

The study adopted descriptive survey and used quantitative methodology to collect data, via the use of questionnaire from 376 registered users that were randomly sampled for the study. Based on a response rate of 75.2%, the study revealed that both library users and their libraries are responsible for the observed critical factors affecting demand for information resources, among the university libraries in NorthWest Nigeria. While users were not following the appropriate technique for demanding information resources, it was discovered that university libraries were not good enough in providing current and up to date information resources to their users. The study shows that users of university libraries in NorthWest Nigeria are fairly satisfied with information resources they demand because of the poor articulation of their information needs and their inability of using catalogue to demand for information resources. Other issues critically affecting demand for information resources include users' inability of using boolean search techniques, outdated or non-current resources as well as inadequate computer and other information technology hardware for accessing information resources.
