Delphi Analysis

In this chapter, we elaborate on effects of recently induced digitalization of teaching, and consequently on innovative learning. A series of workshops on using digital tools in the teaching process—performed by teachers for teachers—was used to conduct a two-level analysis on how digitally supported teaching is performed. In the first level, a teachers Delphi analysis was performed, in the second level, we observed teacher performance in the role of learners, examining the user experience of multiple digitally supported teaching technologies. The study reveals that only some elements of innovative learning, i.e. understanding, commenting and providing feedback, modifying the environment and upgrading the learning content were positively influenced by digital technology. The proposed text can provide value-added for teachers in preparing their on-site and on-line courses; furthermore, it provides educational organization backgrounds on how to deliver adequate support for their staff, and finally: it gives learners an insight into how to participate in an innovative course.

In any petroleum product, a high sulphur content is considered undesirable. Sulphur in diesel fuels is claimed to aggravate problems of wear and deposit. With residual oils used in some metallurgical operations, the sulphur combustion products can have an adverse effect on the metal. In combustion equipment, the oxides of sulphur together with water vapour can lead to undesirable acid condensatlon on cool metal surfaces.The more general problem is air pollution. Local and national legislation present the oil industry with a continuing demand for fuels of lower and lower sulphur content. Best use must therefore be made of crude oils of inherently low sulphur content. Desulphurising processes are comnonly used for distillates and are available for residual products. Such processes however tend to add significantly to produetion costs.

Subject Uganda's gold trade. Significance In late February, Ugandan President Yoweri Museveni officially opened a gold refinery at Entebbe, although it has operated since 2014. The 20-million-dollar facility -- set up by the joint Belgian-Ugandan African Gold Refinery (AGR) -- is the second dedicated gold refinery opened in sub-Saharan Africa (the other is in Johannesburg). Once fully operational, the Entebbe site will process up to 150 kilogrammes of gold per day from across Central and Eastern Africa. Impacts With Uganda’s nascent oil industry not yet on line, increased gold exports are welcomed and require little infrastructure for high volumes. Scrutiny from the international community, especially human rights groups, will increase as gold exports rise. A repeal or weakening of the Dodd-Frank Act would reverse progress in managing Great Lakes conflict minerals.

<p class="Abstract">Existing E-learning standards and specifications present a great basis for the development of E-learning, on line and distance learning contents that are accessible, interoperable, durable and reusable.  E-learning contents are supported by these standards as well as by the LMS (Learning Management System)   or web technologies compliant to them. However, simulation based contents or learning objects are less integrated in the E-learning contents than other learning objects, partially because standards and specification don’t pay much attention to more specify them in term of metadata requirements.</p>The main objective of this paper is the elaboration of a new Metadata model on the basis of Learning Object Metadata (LOM) with a wider scope that could support more easily simulation objects, especially in experiential E-learning content in which simulation activity should be executed by the learner, monitored and tracked by the tutor completely on the LMS.

The Fourier Transform

In the past few years on-line digital television frame store devices coupled to computers have been employed to attempt to measure the microscope parameters of defocus and astigmatism. The ultimate goal of such tasks is to fully adjust the operating parameters of the microscope and obtain an optimum image for viewing in terms of its information content. The initial approach to this problem, for high resolution TEM imaging, was to obtain the power spectrum from the Fourier transform of an image, find the contrast transfer function oscillation maxima, and subsequently correct the image. This technique requires a fast computer, a direct memory access device and even an array processor to accomplish these tasks on limited size arrays in a few seconds per image. It is not clear that the power spectrum could be used for more than defocus correction since the correction of astigmatism is a formidable problem of pattern recognition.

Minimum Distances

A Scanning Transmission Electron Microscope (STEM) was coupled to a small computer. The system (see Fig. 1) has been built using a Philips EM400, equipped with a scanning attachment and a DEC PDP11/34 computer with 34K memory. The gun (Fig. 2) consists of a continuously renewed tip of radius 0.2 to 0.4 μm of a tungsten wire heated just below its melting point by a focussed laser beam (1). On-line operation procedures were developped aiming at the reduction of the amount of radiation of the specimen area of interest, while selecting the various imaging parameters and upon registration of the information content. Whereas the theoretical limiting spot size is 0.75 nm (2), routine resolution checks showed minimum distances in the order 1.2 to 1.5 nm between corresponding intensity maxima in successive scans. This value is sufficient for structural studies of regular biological material to test the performance of STEM over high resolution CTEM.
