Aerobic digestion of local slaughterhouse wastewater by activated sludge
More LessCompanies around the world produce waste as a by-product of their products. The waste products are classified as solid wastes, medical wastes, wastewaters, and different kinds of wastes. Overall, the wastewaters have the highest impacts on the environment, since they are discharged into the seawater, and might also be discharged into the municipal wastewaters. In addition, the composition of the wastewater varies from Read More

Developing a risk management approach for portfolio cost control
More LessAuthors: Ahmed Hassan Al-Sulaiti, Nashwan Dawood and Mohamad KassemThe assessment and prediction of the impact of risks on the financial performance of portfolios is a very challenging task, and many portfolios in Qatar and worldwide are still suffering from cost overruns. This aspect is undeveloped in the body of literature on portfolio risk management, and very few studies have addressed this need. Therefore, organisations and portfolio managers are still looking for tools and techniques wh Read More

High Temperature and High Pressure Rheology of Nanofluids: a case study
More LessAuthors: Khalifa Taimour, Anoop Kanjirakat, Reza Sadr and Khalifa TaimourNanotechnology is foreseen to change our life by bringing new horizons to current industrial applications. It could be used, for example, to improve the performances of heat exchangers--which are widely used in industrial applications--by augmenting heat transfer characteristics of the working fluids. Nanofluids, which are engineered colloidal suspensions of nano-sized particles (less than 100nm) dispersed in a base fluid, have s Read More

Development of visualization models to guide the design of future generations of synthetic fuels from natural gas
More LessAuthors: Moiz Bohra, Jahanur Rahman, Elfatih Elmalik, Jan Blank and Nimir ElbashirAs part of the ambition to capitalize on Qatar's gas resources we investigated the potentials of gas-to-liquids (GTL) based jet fuels. These fuels consist of similar carbon cuts as oil-derived fuels, yet they are considered ultra-clean because of their extremely low sulfur and aromatics contents. However, because of this difference, GTL based jet fuel requires additional development to meet the strict aviation industry standards. T Read More

Carbon footprint of the vinyl chloride monomer process
More LessQatar has experienced an unprecedented development in recent years as a result of its large oil and gas industry. It has the third confirmed reserve of natural gas in the world. With 55.4 tonnes of carbon dioxide per person, Qatar has the highest carbon footprint globally, about 10 times the global average. Against this background, there have been attempts to investigate ways to reduce carbon emissions since CO2 was d Read More

Carbon mineralization at low temperature: prospects and challenges
More LessAuthors: Karam Al-Ahmed and Farid BenyahiaGlobal warming and climate change has been linked to green house gas emissions into the atmosphere with an overwhelming scientific evidence supported by a variety of field measurements over a period of time. CO2 has been identified as a major contributor to global warming because of its high concentration in the atmosphere. The bulk of the recent CO2 increase in concentration in the atmosphere has been attributed t Read More

Design and fabrication of a device for carbone capture in mobile emission sources
More LessAuthors: Ihab Naser, Said Osman and Samer AhmedCarbon capture and sequestration (or carbon capture and storage, CCS) is considered to be a critical strategy worldwide--and in Qatar as well--to limit carbon dioxide (CO2) emissions; the main greenhouse gases responsible for global warming. This work focuses on designing a simple device for CO2 capture that can be used in mobile systems like vehicles and ships. The device mainly consists of a compact cylinder filled with Read More

Enhancing seed germination of Acacia tortilis by breaking dormancy using different treatments
More LessAcacia tortilis (subsp. raddiana) Trees are very important in Qatar. The trees play an important role as a source for animals feed and for environmental enhancement by combating desertification and firewood. This study was carried out in the Genetic Resources Department, Biotechnology Center, Ministry of Environment, Qatar and Egyptian Deserts Gene Bank, Egypt. The aim of the study was to enhance the Read More

Environmental sustainability in education city: Green beacon or green island?
More LessAuthors: Mari Luomi, Muhammad Bilal Shakir, John T. Crist, Bushra Alam and Dana QaroutMost countries in the world are faced with the dilemma of missing one or more crucial ingredients that prevent them from engaging in environmental research or implementing environmentally friendly policies and practices. Some countries that have the resources to affect change suffer from a lack of political will, whereas others that may have the political will lack the human or technological resources or institution Read More
