The current study is a laboratory investigation to estimate the levels of activity concentrations of Naturally Occurring Radioactive Materials (NORM) in groundwater in the Dukhan area in the State of Qatar. The primary radionuclide associated with clear gamma-ray decay signatures of concern in NORM wastes is 226Ra (from the 238U decay series) and its decay progenies 214Pb and 214Bi. Previous studies which were conducted Read More

Abstract Background: The plant growth and production rely on the supporting favorable environmental conditions throughout its growing stages. In harsh environmental conditions such as in Qatar, agricultural growth is limited by water availability, salinity and drought, leading to low yield. In soil, there are different kinds of microbiota including fungi, bacteria, actinomycetes, algae as well as various types of plant species. Fungi are Read More

Municipal solid waste management is one of the major challenges facing Qatar with more than 2.5 million tons of municipal solid waste each year, a very high waste generation rate in a country with small land mass. Solid waste in Qatar consists mostly of organic materials (60%) with the remaining made up of recyclables, such as glass, metals and plastics. Qatar's ambitious development strategy targets environmental su Read More

The Northeastern Qatari coast is comprised of diverse and sensitive flora and fauna such as seagrass meadows, turtles, algae, and coral reefs/patches that tolerate harsh environmental conditions. In the near future, this area may see a rise in anthropogenic activity in the form of coastal development projects, which will add to the existing natural stresses, such as high temperature, high salinity and low rates of pre Read More

Organic electronic devices based on polymers received significant attention in the last decade, especially for organic photovoltaics (OPVs) and field-effect transistors (OFETs) despite their performances and stability clearly falling short of today's state-of-the-art crystalline silicon or copper indium germanium selenide (CIGS)-based devices. Flexibility in the manufacturing, light weight, lower fabrication cost, ease of integration into v Read More

In order to ensure long-term sustainability of the reservoir, the gas industry in Qatar is faced with the challenge of reducing the volume of produced and process water (PPW) sent to disposal wells by 50% [1-3]. Recently, Qatargas initiated a project to recycle process water and thus, reduce disposal volumes using commercial advanced water treatment technologies [4]. One emerging technology, “osmotic concentrati Read More

The Khor Al-Adaid “Inland sea” in Qatar is a unique desert lagoon, located in the South east of Qatar and is characterized by a distinct salinity gradient (ca. 4% halite salt to saturated conditions). In the framework of the QNRF funded NPRP project, researchers from Qatar, Germany and Austria have succeeded to isolate and cultivate a new unicellular eukaryote (protist) from Qatar's unique Inland Sea (Khor Al-Adaid). Initi Read More

GCC's climate has a high ambient temperatures throughout most of the year, therefore, the air conditioning is not optional or luxury, it is a necessity. Residential sector in those countries represents the largest portion of electricity consumption. According to Qatar National Development Strategy (QNDS) 2011-2016, two-thirds (67 percent) of total residential power consumption in Qatar is due to air conditioning units (AC), Read More

The coalescence of a water drop in a dieletric oil phase at a water layer interface in the presence of an electric field is simulated by solving the Navier-Stokes and charge conservation equations with the finite element method. The proprietary software Comsol Multiphysics is used for this purpose. The interface between the oil and water phases is tracked by implementing a level-set approach. Preliminary simulations to as Read More
