Application of central composite design to optimize culture conditions of chlorella vulgaris in a batch photobioreactor: An efficient modeling approach
Microalgae cultivation and their use is a promising approach for integrated CO2 biofixation, wastewater treatment and renewable energy production. To develop such an important technology, there is a need to optimize the culture conditions, maximizing CO2 consumption, degrading the nutrients present in the wastewater and maximise the microalgae biomass production.

Ergonomic practices in Africa: Date palm work in Algeria as an example
Despite the call for the application of ergonomics in developing countries, the African share of ergonomic studies is modest. Date palm farming is considered one of the most important economic resources in hot and dry areas. In African countries, including Algeria, there exist millions of date palms. Date palm work [...]
Smart City: A review of maturity models
Smart City is an emergent strategy and solution for the urbanization problems and the investments in its worldwide market are rapidly. However, the Smart City maturity models are discussed in very few scientific research papers and it is uncertain whether the existing maturity models can fulfil their proposed objectives. Also, [...]
Energy load forecasting: Bayesian and exponential smoothing hybrid methodology
Purpose: The purpose of this study is to present a hybrid approach to model and predict long-term energy peak load using Bayesian and Holt–Winters (HW) exponential smoothing techniques. Design/methodology/approach: Bayesian inference is administered by Markov chain Monte Carlo (MCMC) sampling techniques. Machine learning tools are used to calibrate the values [...]
Smart sustainable neighbourhood design: A prototype for Bahrain
The harm caused by the inefficient designs of contemporary cities to the environment is abysmal. Demands for new cities continue to rise due to the growing global populations. The literature discussed the increasing harm caused by such growths on the environment and their negative impact on the physiological and psychological [...]
Streets are forever: thermal coefficient of street orientation as a strategy to develop cooler street networks in hot climates
Maximizing the annual season of street comfort in hot climates requires synergies between all planning and design features. The absence of such combination compromises comfort and planning goals, like increasing walkability. Street orientation is both a determinant of its solar intake and a design feature that outlasts all others. In [...]
Safety mapping for the transportation of raw sewage by trucks in Bahrain
As the Kingdom of Bahrain’s population and development expand, sewage transport outside the national sewer network becomes an ever increasing requirement. Due to the risk associated with sewage transport, an evaluation of industry safety practices has become necessary. Four main factors were selected to make a comprehensive safety assessment model, [...]
Towards an effective environmental impact assessment (EIA) in the industrial sector of Bahrain, Arabian Gulf
Rapid economic and industrial developments and population growth in Bahrain are associated with increases in energy demand and greenhouse gas emissions. An Environmental Impact Assessment (EIA) process has been adopted in the country to address environmental aspects within energy intensive projects such as oil and petrochemical industries. The quality of [...]
Investigating the barriers to change management in public sector educational institutions
Purpose: The purpose of this paper is to explore barriers to the change management in the public sector of educational institutions such as public schools of the Ministry of Education in the GCC countries. The exploration of the research is based on the ADKAR change management model that consists of [...]
