This paper presents a summary of the results of a one-year student-faculty research project on environmental sustainability in Qatar's prime knowledge economy vehicle, the Qatar Foundation (QF), and its home, Education City (EC), in Doha. The project's main objective was to produce new information on the emergence of environmental sustainability policy and practice on the QF's agenda from a number of angles. The research team adopt Read More

The objective of this study was to investigate the effect of treatment of whole barley grain (WBG) with sodium hydroxide (NaOH) on in vitro rumen gas production parameters and microbial protein synthesis. Experimental treatments included untreated whole barley grain (BControl) and treated barley grain with NaOH+water (35 g+220 ml/kg DM WBG) for 30 days (BNaOH). In vitro gas production technique was used to determine the gas pr Read More

The objective of this study is to evaluate sand encroached degradation in arid-land, with a predominantly agricultural ecosystem, using geospatial technologies. The study primarily involves the assessment of land degradation severity, severity change dynamics and temporal land-use change patterns, such as growth or shrinkage. Land use/land cover (LULC) change dynamics were analyzed for eight featured classes, derived using Read More

The sweetpotato weevil, Cylas puncticollis Boheman, constitutes a major constraint to sweet potato production and utilization in Africa. Host plant resistance/tolerance, mulching and varying harvesting dates could provide an approach that fits well into an integrated pest management programme of this insect pest. In this study, a trial was conducted to evaluate the effect of host plant, mulching with freshly harvested, dried and choppe Read More

A maximum of 8.75 wt% hydrogen adsorption was observed by carbon fibers which were obtained by the pyrolysis of cotton. Cotton was pyrolysed at 750°C for 3 h in argon atmosphere. Carbon fiber was soaked with 0.1M Ni(NO3)2. This was filtered and dried at 100°C. Finally, metal nitrate treated carbon fibers were heated at 850°C for 3 h in argon atmosphere. Carbon fibers thus obtained were found to absorb hydrogen to the extent o Read More

A new chromium(III) salt (C3H5N2)[Cr(C2O4)2(H2O)2].2H2O, trans-diaquabis(oxalato) chromate(III) imidazolium dihydrate, has been synthesized and characterized by single crystal X-ray diffraction. This compound crystallizes in the monoclinic system, C2/c space group with a = 10.836(1)Å, b = 7.541(1)Å, c = 16.349(3)Å and β = 93.52(1)°. The structure of the title compound consists of [Cr(C2O4)2(H2O)2]−  mononuclear anions, i Read More
