Qatar Foundation Annual Research Conference Proceedings Volume 2014 Issue 1

Background: Water management is a key focus area globally, and especially for the state of Qatar given its extremely arid environment. As such, research to develop technologies to enhance beneficial re-use of treated industrial waste water is recognized as a key challenge in this region. As a part of the Water Re-Use Research Program at ExxonMobil Research Qatar, a model was developed in collaboration with Simon Fraser U Read More

The international GEM collaboration is working on instrumenting the high-? region of the CMS endcap with Gas Electron Multiplier (GEM), a candidate detection system for muon particles that could resist the high luminosity and strong magnetic field present in that region. It consists of a thin polymer foil, metal coated on each side and pierced by a high density of holes (see figures). The potential difference between the el Read More

ABSTRACT Coral ecosystems are very important as they provide a foundation habitat to many aquatic species. Laboratory experiments (microcosms: ecosystems under controlled conditions) were initiated to understand Qatari corals physiology. Coral samples were collected and nubbins were cultured in pre-acclimatized laboratory aquaria. Acute orthogonal experiments for two weeks were conducted to test the Read More

Among different crystal structures and morphologies of TiO2, vertically oriented anatase nanotube arrays show the highest activity for solar energy conversion. However, the long-standing bottleneck is the fact that TiO2 is a wide band gap semiconductor, limiting its activation to the deep-blue and ultraviolet spectral region that contains but a small fraction (5%) of the incident solar energy. Herein, density functional theory (DFT) Read More

Mature oil fields are characterized by a high water cut (ratio of water over the total liquid) with the water production sometimes reaching nine times the oil production. Under such extreme conditions, current monitoring technologies such as multiphase flow meters have a decreased accuracy and reliability. The safe and cost-effective operations of fields with high water cut - and/or high gas volume fraction - requires c Read More

On a global level, the IEA estimates that buildings are responsible for more than 40% of the total primary energy consumption (Howe and Gerrard, 2010). In Qatar, RQPI estimates that buildings are responsible for 33% of the country's carbon dioxide emissions (RQPI, 2012). Reducing buildings' energy consumption in Qatar provides an opportunity to reduce its environmental impact as it currently globally ranks first in CO_2 emis Read More

Thermoelectric materials and generators provide the unique capability to directly convert waste heat into electricity. Especially, generators which are suitable for high temperatures up to 600°C have a wide field of application, ranging e.g. from automotive applications to cogeneration power plants. In contrast to alternative waste heat recovery technologies such as the Organic Rankine Cycle, thermoelectric generators work n Read More

Micropropagation of Date Palm (Phoenix dactylifera L.) is being practiced for more than two decade by laboratories or commercial enterprise. Most published protocols are using the MS media in different stages for propagation. This media is either purchased as a ready-made mix or mixed from stock solutions prepared from high grade chemicals. The price of the MS affecting directly the sale price of the produced plantlets. A no Read More
