Full text linkThe political though of Amilcar Cabral, 1979
No full textThe purpose of this .thesis is to examine the political thought of Amilcar Cabral. We will isolate the central elements of his political thought by textual analysis of primary and secondary works with particular emphasis on the writings of Cabral. In that Amilcar Cabral's thought developed through the movement for national liberation in Guine-Bissau, that movement will be explored to give clarity to our analysis. However, the emphasis remains on the genesis and development on Cabral's thought. We will identify the character of Cabral's political thought as a comprehensive political philosophy in the successive phases of the struggle to simultaneously achieve power and transform the Guinean reality. The major question asked is "what is Amilcar Cabral's political thought?" We intend to investigate whether or not Amilcar Cabral's political thought altered the political, social, and economic situation of Guine-Bissau. In the first chapter, we will try to identify who was Amilcar Cabral, the man. We will investigate his educational background, the social milieu in which his thought developed, and his personal history. We also will examine his character as the head of a movement for social change. In the second chapter, we intend to establish key environmental problems in the field of political thought. We will attempt to evaluate the role of philosophy and the nature of political theory as a field of inquiry. Subsequently, we intend to evaluate the condition of political thought specifically in Guine-Bissau prior to the national liberation movement. In the third chapter, we will briefly look at the history of Guine-Bissau and the political party started by Cabral, the African Party for Independence in Guine and Cape Verde (P.A.I.G.C.), We hope to illuminate the historical facts that distinguish and particularize the totality of conditions in Guine-Bissau. In the fourth chapter we will present Cabral's thought as a comprehensive analytical system. We intend to identify the core assumptions that actuate Cabral as a political thinker. We also intend to discuss the mechanisms he proposes to use in implementing political thought and the goals. he hopes to achieve by doing so. In the fifth chapter we will evaluate Cabral's political thought. We intend to analyze the components of his thought that distinguish him as a political thinker. We plan to determine if Cabral's thought altered the concrete conditions of GuineBissau that existed prior to its introduction. We will also examine the theoretical nature of Cabral's thought to assess its character as political theory. In the summary, we will relate the findings of our investigation of Amilcar Cabral's political thought. We hope to draw conclusions as to the method of inquiry practiced by Cabral. Finally, we will appraise the importance of Amilcar Cabral as a political thinker we hypothesize that the findings will confirm our underlying assumption that Cabral's thought is identifiable and significan
Preparation of mesoporous Ti - Organosilicate epoxidation catalysts, 2008
Full text linkFollowing the methodology used in solgel chemistry to functionalize amorphous silica, organic functionalized mesoporous silica were prepared by the co-condensation of tetraethoxysilane and organoalkoxysilanes in the presence of surfactant templates. A series of titanium catalysts containing Ti-MCM-41 with different bridging and pendant organic functional groups (such as methyl triethoxysilane (MTEOS), phenyl triethoxysilane (PTEOS), diphenyl triethoxysilane (DPTEOS), bis (triethoxysilyl) ethane (BTSE), 1,4 bis(triethoxysiyl) benzene (BTSB), bis( triethoxysilyl) biphenyl (BTSDP) and two catalysts with different organic-inorganic ratios (90% TEOS with 10% phenyl, 70% TEOS with 30% phenyl) were synthesized. The catalysts were characterized by elemental analysis, XRD, FTIR, UVDRS, by solid state 13C and 29Si MAS NMR, and BET surface area analysis. The catalytic activities of the synthesized materials were evaluated for epoxidation of cyclohexene with TBIIP. The materials yielded improved conversion compared to the conversion results obtained from the traditional titanium containing mesoporous silica (Ti-MCM-41). The hydrophobic character of the synthesized catalysts was tested in the epoxidation of cyclohexene by using wet TBIIP. Ti-MCM41 with bridged organosilane showed almost the same conversion in the presence of water, while for Ti-MCM-41 with organosilane pendant groups. conversion decreased almost 36%. This implies that the silylation of the surface ofTi-MCM4I protected the active sites. The effect of substrate: oxidant molar ratio in these reactions were studied and high conversion, high selectivity were achieved at 1:1 molar ratio
The addition of bromine to 1-para-nitrophenyl-4-phenylbutadiene 1,3-1-carboxylic acid, 1943
No full textSuccessful leadership characteristics of elementary school leaders and the impact on consecutive student achievement, 2013
Full text linkThis dissertation provides important research for aspiring and current administrators. It provides data on select leadership characteristics and the impact on student achievement. The problem was inconsistent student achievement in select elementary schools of the local education agency. The Local Education Agency (LEA) selected for the study has a total of 81 elementary schools. During the 2010 and 2011 school years, 41 elementary schools achieved adequate yearly progress. The challenge in the LEA is the creation of sustained student achievement across all elementary schools. The purpose of the study was to examine if there was a significant relationship between student achievement and select leadership characteristics at the elementary school level. The researcher chose a mixed method design to explore student achievement and select leadership characteristics. Mixed method was the chosen design because it combined the strength of both the quantitative and qualitative method. Data revealed that school climate, instructional supervision, leadership style, structured operational environment, teacher recognition, teacher training, team collaboration, shared leadership and decision making, and school encouragement of parental engagement had a significant relationship with student achievement. This is significant for all educational leaders as we strive for positive student achievement for schools in the 21 st century
Iron-oxide embedded phema nanocomposite hydrogel for malachite green removal from free-flowing streams, 2015
Full text linkThe aim of the study is to synthesize new nanocomposites consisting of superparamagnetic iron oxide nanoparticle (Fe3O4) incorporated into poly(2- hydroxyethyl methacrylate) hydrogel (pHEMA) in different ratios (75% and 100%). These materials can be used in water treatment and can be easily removed/controlled by an external magnetic field. The nanoparticles were synthesized by a co-precipitation method and then embedded in pHEMA to produce magnetic pHEMA nanocomposite hydrogel (mHEMA). PHEMA was synthesized by free radical polymerization. The resulting data for mHEMA were compared to those obtained from pHEMA hydrogel. The adsorption of malachite green (MG) dye onto pHEMA and mHEMA was carried out in this project. The effects of different parameters such as the initial MG concentration and contact time on MG adsorption were investigated. The hydrogels were characterized by Scanning Electron Microscopy (SEM) and X-ray diffraction (XRD) techniques to confirm the presence of Fe3O4 nanoparticles inside the pHEMA hydrogel. A density test was used to show that the mesh size of 75% mHEMA, 100% mHEMA and pHEMA hydrogels were 8.5, 43.9 and 67.7 A, respectively. The adsorption equilibrium data of mHEMA were best represented by the Langmuir model. The maximum adsorption capacities of 100% and 75% mHEMAs were 5.91and 11.06 mg/g in the wet state and 3.45 and 9.90 mg/g in dry state, respectively. This study found that pHEMA hydrogel had a higher maximum adsorption capacity, 15.94 mg/g in wet state and 15.28 mg/g in dry state, than mHEMAs

Woodruff Library and the Library Advisory Council hosted an exhibit and reception celebrating the published works of Atlanta University Center faculty. As a complement to that event, the Robert W. Woodruff Library presents this publication, Atlanta University Center Faculty Publications: A Brief Bibliography, which highlights selected scholarly and research contributions of the Atlanta University Center faculty. The celebration has become an annual event and the bibliography illustrates the richness of faculty contributions within each institution and across the Atlanta University Center community. It should be viewed as a fluid document to be updated as new contributions emerge and will be preserved on the Librarys website for future reference and use
Structural and electronics properties of noncovalently functionalized graphene, 2013
Full text linkRecent experimental work has demonstrated production of quasi free-standing graphene by methane intercalation. The intercalation weakens the coupling of adjacent graphene layers and yields Dirac fermion behaviour of monolayer graphene. We have investigated the electronic characteristics of methane intercepted graphene bilayer under a perpendicularly applied electric field. Evolution of the band structure of intercalated graphene as a function of the bias is studied by means of density-functional theory including interlayer van der Waals interactions. The implications of controllable band gap opening in methane-intercalated graphene for future device applications are discussed. Noncovalent functionalization provides an effective way to modulate the electronic properties of graphene. Recent experimental work has demonstrated that hybrids of dipolar phototransductive molecules tethered to graphene are reversibly tunable in doping. We have studied the electronic structure characteristics of chromophore/graphene hybrids using dispersion-corrected density functional theory. The Dirac point of noncovalently functionalized graphene shifts upward via cis-trans isomerism, which is attributed to a change in the chromophore's dipole moment. Our calculation results reveal that the experimentally observed reversible doping of graphene is attributed to the change in charge transfer between the light-switchable chromophore and graphene via isomerization. Furthermore, we show that by varying the electric field perpendicular to the supramolecular functionalized graphene, additional tailoring of graphene doping can be accomplished
