It has become firmly established the productivity is the real source of and important for economic growth of any country; it has an essential role in the economies of developed and developing countries alike. It allows the nation to raise its standard of living, to support such social goals as education and health care, and to contribute to other aspects of the general welfare; it is an essential underpinning of the nation's security (Stupak and Leitner, 2001). Increased productivity is the key to economic progress, where the standard of living of communities and income levels depend on the progress of the level of productivity; higher levels of productivity in economies lead to increased rates of growth and prosperity (Seid, 1996).

This work is focused on nucleation stages during isothermal austenite transformation in two types of Vanadium micro-alloyed steels. Isothermal treatment was carried out in the temperature range 350 to 600οC. Metallographic evaluation using optical and scanning electron microscopy (SEM) enabled determination of the nucleation curves of isothermally decomposed austenite. Three curves are found to be relevant to this initiation stage of transformation: first curve is related to grain boundary nucleated ferrite (GBF), second curve is related to intra-granularly nucleated ferrite (IGF) and the third to pearlite (P) curve. GBF and IGF curves are divided into two regions, which represents the high temperature and the low temperature segments as consequence of either displacive nature of transformation or diffusion transformation. Addition of Ti to V – micro-alloyed steel in this work seems to be balanced by a slightly higher C and Mn content, leading to limited effect on nucleation stage of austenite decomposition.

Research was conducted at Curtin University (Western Australia) to assess the seedling tolerance of three species Eucalyptus, gomphocephala DC (Myrtaceae) (common name ‘Tuart’), Eucalyptus marginata Sm. (common name ‘Jarrah’) and Corymbia calophylla (Lindl.) K.D. Hill & J. A. S. Johnson (common name ‘Marri’) to soil-induced stressor, namely water loggings (flooding). Flooding treatment was achieved by filling the tubs with water, approximately 1 cm above the soil surface and control treatment had the same method except with drainage holes. Study assessment was attained by statistical change in seedling growth, leaf allocation and leaf physiology after 70 days of seed germination. Tolerance was assessed by measuring changes in seedling growth, leaf allocation and leaf physiology after 70-80 days. C. calophylla was the most tolerant to prolonged waterlogging (80% survival, no difference in transpiration rates); E. marginata was the least tolerant (10% survival, 95% decrease in transpiration rate). E. marginata was the least tolerant to the three soil stresses. E. marginata prefers habitats that are not excessively wet on well-drained soils. C. calophylla was the most tolerant, occurring and tolerating wet, well-drained soils and thus demonstrated better physiological responses of three prominent studied eucalypts to soil-induced stresses provides us with invaluable knowledge for rehabilitating and restoring urban bush land.tolerance to prolong waterlogging. Knowing the seedling growth and

The paper has evaluated a sample of material which focuses on the teaching of vocabulary in Libyan Primary Schools. The major objective was to examine the underlying organising principles, teaching approaches and the learning processes, and to discover any shortcomings that might hinder the achievement of the intended outcomes. To fulfil this aim, as much information as possible was collected from various resources such as books, theses, study papers, journals and the World Wide Web. The discussion of the topic has covered three main points. They are a review of the relevant literature, analysis and evaluation of the material in question and, finally, suggestions of how this material might be improved. Because it was difficult to assess the material in isolation, reference to other involved factors such as the teacher, the student and the teaching/learning environment was occasionally made

Mobile augmented reality is growing rapidly because of the growth of smartphones. Due to the portable

nature of smartphones, mobile augmented reality devices have become the most widely deployed consumer

augmented reality display device and show promise for becoming the first commercial success for augmented

engagement and interactivity are the main two factors of influenced learning where the engagements are focused in

An integrated framework consisting of three above stated modules is proposed in this paper

The use of gas for power generation is likely to increase in the medium term. Also, the introduction of new fuels will ensure a higher generation with lower emissions under continuous operation. These scenarios lead to the conclusion that there will be a considerably more diverse range of fuel supply. However, the use of these new fuels contrasts with recent experiences of global operators who report increasing emissions and difficult combustion dynamics with even moderate variations in their fuel characteristics. Clearly there are significant challenges for fuel flexible gas turbines, particularly emission control, combustor dynamics and flame stability.

Trials using a power derivative gas turbine combustor and a high hydrogen content fuel produced unusual flashback events, in that flashback was induced by either leaning of the fuel mixture by the increase of combustion air, or by a change in composition through the reduction of methane pilot fuel. The introduction of CO₂ through the combustors pilot injector prevented flashback from occurring under these circumstances. The resulting reduction of temperature in the combustion zone, indicated by lower burner tip temperatures causes a reduction in the emissions of nitrous oxides, whilst there is minimal effect on the effective turbine inlet temperature, only a 2.3% reduction.

Investigations using a ‘generic’, radial swirl burner and stereo PIV demonstrated how the flashback depended on a combination of flow structure augmentation and changes in mixture burning rate. The injection of methane or CO₂ had differing effect on these parameters of the combustion zone, but both produced combinations that facilitated stability.

This paper presents an analysis of the essential characteristics of the TQM philosophy by comparing the work of five notable authors in the field. A framework is produced which gather the identified TQM enablers under the well-known operations management dimensions of process, business and people. These enablers are linked with sustainable development via balance scorecard type economic and non-economic measures. In order to capture a picture of Libyan Company’s efforts to implement the TQM, a questionnaire survey is designed and implemented. Results of the survey are presented showing the main differentiating factors between the sample companies, and a way of assessing the difference between the theoretical underpinning and the practitioners’ undertakings. Survey results indicate that companies are experiencing much difficulty in translating TQM theory into practice. Only a few companies have successfully adopted a holistic approach to TQM philosophy, and most of these put relatively high emphasis on hard elements compared with soft issues of TQM. However, where companies can realise the economic outputs, non-economic benefits such as workflow management, skills development and team learning are not realised. In addition, overall, non-economic measures have secured low weightings compared with the economic measures. We believe that the framework presented in this paper can help a company to concentrate its TQM implementation efforts in terms of process, system and people management dimensions.
