This study is part of a larger study that explores societal and organizational culture factors that influence the adoption of information systems (IS) in Libya’s Oil and Banking sectors (Twati & Gammack, 2004; 2006). Using a structured survey questionnaire based on the work of Geert Hofstede’s Value Survey Module (VSM 94), 400 questionnaires were administrated to middle and top management employees in more than 15 government and public organizations in the two named industry sectors. The findings showed that there is a direct positive relationship between Hofstede’s (1980) societal culture dimensions and the adoption of IS. The findings also showed that there are no differences in the societal culture dimensions between the two sectors covered in this study. This implies that the adoption of IS is influenced by societal culture and other factors, which are worthy of investigating. The future implications of this research are also discussed

Abstract

This paper presents the effect of corrugation geometry on the crushing behavior, energy absorption, failure mechanism, and failure mode of woven roving glass fibre/epoxy laminated composite tube. Experimental investigations were carried out on three geometrical different types of composite tubes subjected to axial and lateral compressive loadings. On the addition to a radial corrugated composite tube, cylindrical composite tube, and corrugated surrounded by cylindrical tube were fabricated and tested under the same condition in order to know the effect of corrugation geometry. The results showed that the loading carrying capability is significantly influenced by corrugation geometry in axial crushing. However, no affect of corrugation geometry was observed for lateral crushing. Load–displacement curve was plotted for all conducted tests, thus clear comparison between different specimen's geometry was achieved. It is also found that radial corrugation could significantly applicable as a stable and effective energy absorber.

Abstract

A numerical simulation of a two-stage reciprocating compressor has replicated the operations of the compressor under various conditions for the development of diagnostic features for predictive condition monitoring. The simulation involves the development of a mathematical model of five different physical processes: speed–torque characteristics of an induction motor, cylinder pressure variation, crankshaft rotational motion, flow characteristics through valves and vibration of the valve plates. Modelling both valve leakage and valve spring deterioration has also been achieved. The simulation was implemented in a MATLAB environment for an efficient numerical solution and ease of result presentation. For normal operating conditions, the simulated results are in good agreement with the test results for cylinder pressure waveforms and crankshaft instantaneous angular speed (IAS). It has been found that both the IAS fluctuation and pressure waveform are sensitive detection features for compressor faults such as valve leakage and valve spring deterioration. However, IAS is preferred because of its non-intrusive measurement nature. Further studies using the model and experiments are being undertaken in order to develop fault detection features for compressor driving motors and transmission systems.

Sustainable development is not a new concept to Islam, sustainable

development principles have existed for centuries in the Holy Qur'an and the Hadith.

However, sustainable development concept may have been recently adopted for

government and civic society in Islamic world. The Islamic perspective embraces that

everything on earth is created for humanity and God's award to people. Islam allows the

consumption of the natural environment without involving unnecessary destruction. Shariah

views that human activities should support environment, and protection of people’s rights,

and needs ensuring that human activities do not compromise the essentials of social,

economic and natural systems either now or in the future. The aim of this study is to

discover the application of Islam in sustainable development debate. Sustainable

development in the context of Islamic concept is taken as an opportunity to refresh the

relationship between human being and environment. This paper is focusing on literature

review.

Purpose

This study sets out to explore the impact of organisational culture innovation on the adoption of information systems (IS) in Libya's oil and banking sectors.

Design/methodology/approach

Using a structured survey questionnaire based on Cameron and Quinn's Organisational Culture Assessments Instrument (OCAI), 400 questionnaires were administered to middle and top management employees in more than 15 government and public organisations in Libya's oil and banking sectors.

Findings

The findings showed that there is a relationship between organisational culture innovations and the adoption of IS. The findings also showed that there are no differences in the organisational culture type between the two sectors covered in this study.

Originality/value

The findings imply that organisational culture innovations are influenced by other factors, which are worthy of investigation. The future implications of this research are also discussed.

Abstract

This paper is devoted to study the effect of corrugation geometry on the crushing behavior, energy absorption, failure mechanism, and failure mode of woven roving glass fibre/epoxy laminated composite tubes. A comprehensive experimental program has been carried out on two geometrically different types of composite tubes subjected to axial compressive loading conditions. A cylindrical composite tube has been fabricated and tested in order to provide a means of comparison with corrugated composite tube. Both are tested under the same condition to establish the effect of corrugation geometry. The results showed that the initial failure was dominated by interfacial failure, while a folded zone grows progressively down in a form of mushrooming failure. The results also showed that radial corrugated composite tube (RCCT) exhibited good energy absorption capability than circular composite tube (CCT).

 carbon materials2 through their unique combination of excellent processability and high carbon yield. The enediyne functionality of the monomers undergo a thermal Bergman cycloaromatization reaction that yields reactive naphthalene diradicals which polymerize to form polynapthalene.(Figure 1) The tetrafunctionality of the monomers allows for both a higher processing window due to extensive branching and ultimately the formation of network polymers. The high carbon yield results in less shrinkage of the polymer upon pyrolysis to the glassy carbon state. This allows for the faithful templating of carbon structures from a polymeric precursor.

Hydrogen fuel cell electrodes require several properties for optimum performance. An ideal electrode would have as high a surface area as possible with an uniform dispersion of nano-scale catalyst particles attached to the surface. The electrode must be electrically conductive and have good mass transport for products and reactants. Carbon supported platinum is the best known catalyst for the oxidation of hydrogen at the anode and the reduction of oxygen at the cathode of a proton exchange membrane fuel cell (PEMFC) 3. The material also must have good compatibility with the material used for the proton exchange membrane in the membrane electrode assembly (MEA), usually a sulfonated fluoropolymer such as Nafion. We have undertaken a study to prepare a high surface area carbon material through a BODA templating method which can then be functionalized with both well dispersed platinum nanoparticles …
