Modelling the asymmetric responses of price level to oil price changes in Qatar حسب Mrabet, Zouhair

"…Moreover, we find that price responses to negative changes in oil price is greater than its response to positive changes. Given Qatar's economic features, a decrease in oil price could cause lower imports and production prices and consequently a substantial influence on domestic prices level. …"

Pilot-scale petroleum refinery wastewaters treatment systems: performance and microbial communities' analysis حسب Karray, Fatma

"…The reduction of the COD, BOD5, phenols, and the total petroleum hydrocarbon (TPH) reached 82.10%, 85.87%, 91.63%, and 81.11%, respectively at high hydraulic residence time (HRT = 10 days). Decreasing HRT to 5 and 2.5 days led to a decrease in the efficiency of the process and a decrease in biomass concentration was also observed (<1000 mg/l). …"

Towards energy efficient and quality of service aware cell zooming in 5G wireless networks حسب Lateef, Hafiz Yasar

"…The exponential growth of mobile data traffic would lead to dense deployment of small base stations and eventually higher energy consumption in Fifth Generation (5G) wireless networks. We formulate a dynamic cell zooming and base stations sleep optimization algorithm for dense heterogeneous networks as a Linear Programming (LP) problem in order to not only minimize the system power consumption but also to guarantee the quality of service to end user. …"

Superior photocatalytic activity of Cu doped NiWO4 for efficient degradation of benzene in air even under visible radiation حسب Tri N.L.M.

"…The obtained experimental result indicated that photocatalytic performance of the prepared Cu-NiWO4 materials were greater than that of the pure NiWO4. This was because Cu effectively acted as novel dopant, which not only affected valence band (VB) top and conduction band (CB) bottom of NiWO4 but also formed a medium energy level between CB and VB of the NiWO4 to decrease its energy band gap and electron-hole recombination rate. …"
