The main objective of the present research is to investigate the benefits of using geogrid reinforcement in minimizing the rate of deterioration of ballasted rail track geometry resting on soft clay and to explore the effect of load amplitude, load frequency, presence of geogrid layer in ballast layer and ballast layer thickness on the behavior of track system. These variables are studied both experimentally and numerically. This paper examines the effect of geogrid reinforced ballast laying on a layer of clayey soil as a subgrade layer, where a half full scale railway tests are conducted as well as a theoretical analysis is performed.

The experimental tests work consists of laboratory model tests to investigate the reduction in the compressibility and stress distribution induced in soft clay under a ballast railway reinforced by geogrid reinforcement subjected to dynamic load. Experimental model based on an approximate half scale for general rail track engineering practice is adopted in this study which is used in Iraqi railways. The investigated parameters are load amplitude, load frequency and presence of geogrid reinforcement layer. A half full-scale railway was constructed for carrying out the tests, which consists of two rails 800 mm in length with three wooden sleepers (900 mm × 90 mm × 90 mm). The ballast was overlying 500 mm thick clay layer. The tests were carried out with and without geogrid reinforcement, the tests were carried out in a well tied steel box of 1.5 m length × 1 m width × 1 m height. A series of laboratory tests were conducted to investigate the response of the ballast and the clay layers where the ballast was reinforced by a geogrid. Settlement in ballast and clay, was measured in reinforced and unreinforced ballast cases. In addition to the laboratory tests, the application of numerical analysis was made by using the finite element program PLAXIS 3D 2013.

It was concluded that the settlement increased with increasing the simulated train load amplitude, there is a sharp increase in settlement up to the cycle 500 and after that, there is a gradual increase to level out between, 2,500 and 4,500 cycles depending on the load frequency. There is a little increase in the induced settlement when the load amplitude increased from 0.5 to 1 ton, but it is higher when the load amplitude increased to 2 ton, the increase in settlement depends on the geogrid existence and the other studied parameters. Both experimental and numerical results showed the same behavior. The effect of load frequency on the settlement ratio is almost constant after 500 cycles. In general, for reinforced cases, the effect of load frequency on the settlement ratio is very small ranging between 0.5 and 2% compared with the unreinforced case.

Increasing the ballast layer thickness from 20 cm to 30 cm leads to decrease the settlement by about 50%. This ascertains the efficiency of ballast in spreading the waves induced by the track.

The purpose of this paper is to attempt to bridge the gap between sustainable housing and the use of smart technologies to improve the level of sustainability in the housing construction in Saudi Arabia, by discussing the barriers and enablers concerned with applying sustainability to housing construction in Saudi Arabia, which utilises smart technologies.

A Delphi method survey was employed, for which 25 individuals from three key stakeholder groups of the Saudi housing sector participated. They were asked about their degree of agreement (or disagreement) about the various barriers and enablers of applying sustainability to housing construction in Saudi Arabia, which utilises smart technologies. This research paper must be considered as an indicative study of selected experts that do not represent in any way the total population of Saudi Arabia.

Lack of public awareness has been identified as the most significant barrier in implementing sustainable housing development in Saudi Arabia, which utilises smart technologies. Raising awareness of the public to the benefits of sustainable housing and enlightening key project stakeholders in the design of sustainable housing are both essential in order to overcome the barriers discussed in this paper. In addition, it is important to adopt smart sustainable construction methods, exemplified by but not limited to, appropriate water preservation and wastewater treatment systems that are simultaneously smart and sustainable.

This particular research has dealt with only barriers and enablers in the application of sustainability to housing in Saudi Arabia, which utilises smart technologies. For a more complete understanding, there is a need for further analysis of supplementary factors.

A study such as this, which identifies and prioritises barriers and enablers, could prove useful in guiding or encouraging the relevant ministry in Saudi Arabia to develop policies founded in the implementation of sustainability to the housing sector.

This research is a preliminary investigation into the implementation of sustainable housing development as it relates to Saudi Arabia.

This study aims to explore how libraries in the United Arab Emirates use technology to preserve and digitize cultural and historical documents. It examined how these institutions use different technology models to facilitate the dissemination of UAE’s cultural traditions, practices, historical experiences and expressions to the local and global populations interested in learning about the country.

This study relied heavily on a review of the relevant literature and case studies covering how UAE libraries use technology to preserve, document and share tangible and intangible cultural heritage. The methodology entailed gathering and synthesizing relevant information from scholarly journal articles, government and reputable institutional resources online and reports. Collectively, it led to a close analysis of the impact of technology on cultural preservation and an assessment of the specific technology models preferred for optimal outcomes in preserving and disseminating cultural heritage information of the UAE.

Multiple UAE libraries rely heavily on technology to collect, record, translate and store cultural heritage information, including releasing it to users when required. The National Archives of the United Arab Emirates, the Arabian Gulf Digital Archive, Mohammed Bin Rashid Library, the UAE National Library and Archives, New York University Abu Dhabi and Khalifa University of Science and Technology and Research libraries have leveraged different technological models and tools to make UAE’s cultural heritage information available and accessible globally. Artificial intelligence and machine learning algorithms, three-dimensional imaging and scanning, electronic archiving systems, document management systems and ICT storage systems have helped the UAE libraries to promote and disseminate the nation’s tangible and intangible cultural heritage.

By relying on scholarly and authoritative sources of information and evidence to draw conclusions, this study contributes to the existing literature by offering insights into the innovative strategies used by UAE libraries to leverage technology for cultural preservation and promotion. In underlining the value of digital approaches to safeguard tangible and intangible cultural heritage, the research highlights the instrumentalism of technology in preserving the UAE’s cultural heritage and identity.

Flows of transnational popular culture into Egypt are not so much cases of foreign imperialism imposing itself on helpless Egyptians as they are processes managed by Cairene entrepreneurs whose accomplishments present them as successful agents of modernization, locating the cosmopolitan balance between global brands and goods and local markets and infrastructures. This chapter explores the links between these entrepreneurs, the state's “culture of development,” and class reproduction. Egyptian transnational entrepreneurialism – speculative, profit-oriented enterprises engaged with transnational flows of brands, commodities, and capital – has become yoked to the state's goal of national development through economic liberalization. Upper-class cosmopolitan entrepreneurs are increasingly positioned as agents of hybridity, culture brokers who can creatively forge links between supposedly rational and universal economic practices of market capital, and local cultural beliefs and values. Successful entrepreneurs are construed as possessing an “entrepreneurial imagination” by means of which they can overcome structural and cultural obstacles and contribute to the development of an Egyptian “enterprise culture.”

The purpose of this paper is to examine the impact of leadership and rewards on the contribution to knowledge sharing in public organizations of the United Arab Emirates (UAE).

Data were collected from 154 employees from various organizational units of a law enforcement organization in the UAE, and structural equation modeling was used to test the proposed hypotheses.

Leadership inspiration was found to be positively effective in enhancing the contribution of knowledge sharing in terms of solving problems, increasing opportunity and improving the productivity of the workforce. Furthermore, it was found that the reward system had no impact on the contribution to knowledge sharing.

The method of data collection focused on the employees who were attending a training workshop in the department. This survey raises concerns related to non-response bias and common method bias, which describes the measurement error that is compounded by the sociability of the respondents who wanted to provide positive answers.

This research focuses on the implementation of certain practices related to knowledge sharing in public organizations. The model was constructed to assess the impact of leadership and rewards on the contribution to knowledge sharing through knowledge sharing practices as a mediation. The study is a modest attempt to assist the organizational leaders to embark on the right steps to foster knowledge sharing behavior among employees.

The study contributes to the literature on knowledge sharing, particularly on the relationship between leadership inspiration, rewards and contribution to knowledge sharing in the law enforcement organizations in the UAE.

The purpose of this paper is to investigate the efforts undertaken by the Gulf Cooperation Council (GCC) countries in deploying renewable energy (RE), in terms of capacity assessments, research and development activities, and current and planned projects.

The purpose of this paper is to describe the principal reasons why Emirate women are under‐represented in the United Arab Emirates (UAE) information technology (IT) sector; and the barriers and challenges that national women have encountered while working in this sector of the national economy.

The paper draws on data from 20 structured in‐depth interviews conducted with Emirate women who had worked for a minimum of five years in IT.

Although national women have made remarkable inroads into almost all professions and occupations in recent years, they are still noticeably under‐represented in IT, particularly in the private sector. In addition, very few are in senior‐level positions and there are, at the time of writing, no Emirate women technology‐entrepreneurs. The results show that cultural and familial factors still inhibit many young Emirate women from choosing careers in this profession, and negative gendered attitudinal assumptions about women are still prevalent within the local IT sector.

The sample size was small, so we were unable to test specific research hypotheses, or compare our results with quantitative cohort surveys conducted in other countries. Nevertheless, the findings warrant additional research, as increasing numbers of Emirate women graduate from local universities with IT/MIS degrees, and further research on this topic is described.

Five practical strategies are identified to encourage more young Emirate women to embrace IT careers in the future.

This is the first research on this issue conducted in the UAE/GCC region.

This study aims to predict the volume changes and collapse potential (CP) associated with the changes in soil suction by using the pressure cell and the effect of initial load on soil suction. Three types of gypseous soils have been experimented in this study, sandy gypseous soil from different parts of Iraq. A series of collapse tests were carried out using the oedometer device [single oedometer test (SOT) and double oedometer test (DOT)]. In addition, large-scale model with soil dimensions 700 × 700 × 600 mm was used to show the effect of water content changes in different relations (collapse with time, stress with time, suction with time, etc.).

A series of collapse tests were carried out using the oedometer device (SOT and DOT). In addition, a large-scale model with soil dimensions 700 × 700 × 600 mm was used to show the effect of water content changes in different relations (collapse with time, stress with time, suction with time, etc.).

The CP increases with the increasing of the void ratio for each soil. For each soil, the CP decreased when the initial degree of saturation increased. Kerbala soil with gypsum content (30%) revealed collapse value higher than Tikrit soil with gypsum content (55%) under the same initial conditions of water content and density, this is because the higher the Cu value of Kerbala soil is, the more well-graded the soil will be. Upon wetting, the smaller particles or fractions of the well-graded soil tend to fill in the existing voids, resulting in a lower void ratio as compared to the poorly graded one. Consequently, soils with high Cu value tend to collapse more than poorly graded ones. The compressibility of the soil is low when loaded under unsaturated condition, the CP for samples tested in the DOTs under stress level 800 kPa are greater than those obtained from collapse test at a stress level of 200 kPa.

The initial value of suction for all soils increases with initial water content decreases.
