A Sociological Analysis Of Religious Educational Institutions, Policies And Discourses In EgyptAsik, Mehmet Ozan 01 February 2007 (has links) (PDF)
In thesis, I intended to sociologically examine the perceptions and practices of the state and different Islamist groups about the religious education in Egypt from the 1970s onwards. I define the religious education as a religious course to which several hours a week are devoted in the curriculum of mass education, and which teaches moral instructions based on the Qur' / an, and basic information about Islamic culture and history. Since the 1970s, the rise of Islamism in Egypt has created strife between the ruling elites and dissident Islamist groups to capture the religious discourse and control the religious socialization in the mass education. This strife has resulted in the emergence of alternative Islamic educational areas (private Islamic schools and Al-Azhar schools). In this context, I used hermeneutic method to analyze the religious educational discourses and institutions of these two main agents &ndash / ruling elites and Islamist groups. The Mubarak regime in Egypt seeks to institutionalize a particular state discourse in religious education in accordance with its own interests. However, the important thing is the reactions of different Islamist (moderate and radical) groups to this state discourse and institutionalization / because, today, these reactions of opponent Islamist groups generates unintended consequences which are subversive to the legitimacy of the regime.

Desenvolvimento, caracterização e avaliação da formação de complexos de inclusão de rutina, avobenzona e ρ-metoxicinamato de octila na presença de ciclodextrinas / Development, characterization and evaluation of inclusion complexes between rutin, avobenzone and octyl ρ-methoxycinnamate with cyclodextrins.Martins, Tercio Elyan Azevêdo 30 August 2018 (has links)
A radiação UV pode causar danos à pele humana, e, evitar estes danos, é uma preocupação crescente para a população e um desafio à comunidade científica. Para uma ação efetiva de fotoproteção, a associação de filtros, como avobenzona (BMBM) e ρ-metoxicinamato de octila (EHMC), são empregados. Devido à semelhança estrutural com os filtros solares químicos, a rutina (RUT), tal como outros flavonoides, apresenta atividade fotoprotetora. Apesar da disponibilidade de diferentes classes de filtros solares, o desenvolvimento de fotoprotetores contendo filtros químicos é um desafio, devido à instabilidade inerente a certos filtros orgânicos. As ciclodextrinas (CDs) são oligossacarídeos cíclicos, de formato tronco-cônico, cuja estrutura externa é hidrófilica e sua cavidade interna central hidrofóbica, com a capacidade de acomodar substâncias lipofílicas, formando complexos de inclusão. A formação dos complexos de inclusão pode levar à alterações de propriedades físico-químicas da molécula hóspede, tais como, solubilidade, fotoestabilidade e biodisponibilidade. O objetivo deste trabalho foi desenvolver, caracterizar e avaliar a formação de complexos de inclusão entre RUT, BMBM e EHMC e as CDs (HPβCD e SBEβCD). Os complexos de inclusão (RUT:HPβCD, RUT:SBEβCD, BMBM:HPβCD, BMBM:SBEβCD, EHMC:HPβCD e EHMC:SBEβCD) foram obtidos pelo método de liofilização e quantificados por cromatografia líquida de alta eficiência (CLAE). Os sistemas binários foram caracterizados em solução, pelo método de equilíbrio de solubilidade, e, no estado sólido, empregando calorimetria exploratória diferencial (DSC), termogravimetria (TG/DTG) e difração de raios-X de pó (PDRX). As substâncias isoladas e os complexos binários foram avaliados quanto à fotoestabilidade em estado sólido, e, em solução. Incremento na solubilidade (X mcg mL-1) foi observado para os complexo RUT:HPβCD (4,13x); RUT:SBEβCD (4,38x); BMBM:HPβCD (43,3x); BMBM:SBEβCD (53,3x); EHMC:HPβCD (12,7x); e EHMC:SBEβCD (70,0x). Os ensaios de DSC, TG/DTG, e P-DRX indicaram a formação de complexos de inclusão para os todos os sistemas, onde a supressão dos eventos endotérmicos característicos das substâncias isoladas foram observados; porém, nos complexos de BMBM, a presença de avobenzona livre no meio foi detectada, sugerindo, que a complexação não foi completa. A formação dos complexos de inclusão promoveu o aumento da fotoestabilidade em todos os sistemas avaliados, tanto no estado sólido, como em solução. Os resultados reportados neste estudo, indicaram que a complexação de substâncias fotoprotetoras com HPβCD e SBEβCD, pode representar, uma estratégia promissora quanto ao aumento da solubilidade e da fotoestabilidade. / UV radiation may cause demage on human skin, and preventing it, is an increasing worry for the population and a challenge to the scientific community. For an effective action of photoprotection, the association of filters, like avobention (BMBM) and octyl ρ-methoxycinnamate (EHMC), are used. Due to the structural similarity with the chemical solar filters, the rutin (RUT), like other flavonoids, shows photoprotective activity. Despite the availability of different classes of sunscreens, the development of photoprotectors containing chemical filters is a challenge, due to the inherent instability of certain organic filters. The cyclodextrins (CD) are cyclic oligosaccharides of truncated conical structure, which external structure is hydrophilic and its internal central hydrophobic cavity, with capacity to accommodate lipophilic substances, forming inclusion complexes. The formation of the inclusion complexes can lead to changes in physicalchemical properties of the host molecule, such as, solubility, photostability and bioavailability. The objective of this work was to develop, characterize and evaluate the formation of the inclusion complexes between RUT, BMBM and EHMC and the CDs (HPβCD and SBEβCD). The inclusion complexes (RUT:HPβCD, RUT:SBEβCD, BMBM:HPβCD, BMBM:SBEβCD, EHMC:HPβCD and EHMC:SBEβCD) were obtained by the lyophilization method and quantified by high performance liquid chromatography (HPLC). The binary systems were characterized in solution, by solubility equilibrium method and in solid state, using differential scanning calorimetry (DSC), thermogravimetry (TG/DTG) and powder X-ray diffraction (P-XRD). The isolated substances and binary complexes were evaluated the photostability in solid state, and in solution. The increase in solubility (X mcg mL-1) was observed for the complexes RUT:HPβCD (4.13x); RUT:SBEβCD (4.38x); BMBM:HPβCD (43.3x); BMBM:SBEβCD (53.3x); EHMC:HPβCD (12.7x); and EHMC:SBEβCD (70.0x). The analysis of DSC, TG/DTG, and P-DRX indicated the formation of inclusion complexes for all systems, where the suppression of the endothermic events characteristic of the isolated substances were observed; however, in the BMBM complexes, the presence of free avobenzone was detected, suggesting that the complexation was not complete. The formation of inclusion complexes promoted the increase of photostability in all evaluated systems, as in solid state as in solution. The results reported in this study indicated that the complexation of photoprotective substances with (HPβCD e SBEβCD). may represent a promising strategy for increasing solubility and photostability.

Influência da rutina na fotoestabilização da avobenzona (filtro UVA) e do ρ-metoxicinamato de octila (filtro UVB) / Influence of rutin in photostabilization of avobenzone (UVA filter) and octyl methoxycinnamate (UVB filter)Pinto, Claudinéia Aparecida Sales de Oliveira 29 May 2014 (has links)
Com o intuito de promover proteção de amplo espectro, na maioria dos protetores solares estão associados pelo menos dois filtros orgânicos (UVA e UVB). A combinação da avobenzona (BMBM), filtro UVA, e do p--metoxicinamato de octila (EHMC), filtro UVB, é conhecida e muito utilizada em formulações manipulas e industrializadas, porém apresenta alteração na absorção espectral após exposição à radiação UV. A estratégia empregada com maior frequência para reduzir a instabilidade da combinação é baseada na adição de agentes fotoestabilizadores. A adição de substâncias naturais em formulações fotoprotetoras vem sendo explorada, especialmente o grupo dos flavonoides, como a rutina, que apresenta resultados positivos em relação à eficácia fotoprotetora. O objetivo principal desta pesquisa foi avaliar o potencial da rutina como substância fotoestabilizadora dos filtros EHMC e BMBM. Foram desenvolvidas formulações contendo os dois filtros associados ou não com rutina de acordo planejamento fatorial em três níveis. As formulações foram avaliadas quanto a eficácia fotoprotetora in vitro aplicadas em placas de PMMA e analisadas por espectrofotometria de refletância com esfera de integração antes e após a exposição à radiação UV. As interações moleculares dos filtros com a rutina foram avaliadas por 1H RMN, DSC, TG e análise qualitativa da supressão do estado energético singleto. A adição de rutina nas formulações contendo 5,0% (p/p) de BMBM e 10,0% (p/p) de EHMC promoveu elevação na conservação do FPS in vitro de 53,9% para 65,8 (0,1% de rutina) e 70,8% (1,0% de rutina). As curvas DSC e TG da rutina apresentaram alterações promovidas pela presença dos filtros BMBM e EHMC, indicando interação entre o flavonoide e os filtros. Após dose de 5760 J cm-2 de radiação UV o valor da razão trans/cis para o filtro EHMC em solução adicionado do filtro BMBM foi elevado de 5,5±0,1, sem adição de rutina, para 12,6±0,4, com adição da rutina. A análise qualitativa da supressão do estado singleto indicou que um dos mecanismos envolvidos na fotoestabilização dos filtros BMBM e EHMC é a supressão do estado energético singleto. Os resultados reportados neste estudo indicaram que a adição da rutina em formulações fotoprotetoras representa um caminho simples e efetivo para elevar a fotoestabilidade da combinação dos filtros BMBM e EHMC. A adição da rutina em formulações fotoprotetoras representa uma estratégia promissora, pois aliada a ação fotoestabilizadora, verificada nesse estudo, esse flavonoide possui propriedades antioxidante e quelante de metais que podem colaborar para o desenvolvimento de formulações fotoprotetoras de amplo espectro com aumento da segurança e eficácia. / In order to promote broad-spectrum protection, most sunscreens are associated with at least two organic filters (UVA and UVB). The combination of avobenzone (BMBM), UVA filter, and octyl methoxycinnamate (EHMC), UVB filter, is well known and widely used in industrial formulations and pharmaceutical compounding, but shows alteration in spectral absorption after UV radiation exposure. The most commonly used strategy to reduce the instability of the combination is based on the addition of photostabilizer agents. The addition of natural substances in sunscreen formulations has been explored, especially the group of flavonoids such as rutin, which shows positive results regarding photoprotective efficacy. The main objective of this research was to evaluate the potential of rutin as a photostabilizer substance of EHMC and BMBM. Formulations were developed containing the two filters associated or not with rutin, according to factorial design at three levels. The formulations were evaluated for in vitro photoprotective efficacy applied on PMMA plates and analyzed by spectrophotometer with integrating sphere reflectance before and after exposure to UV radiation. Molecular interactions of filters with rutin were evaluated by 1H NMR, DSC, TG and qualitative analysis of the suppression of singlet energy state. The addition of rutin in the formulations containing 5.0 % (w/w) BMBM and 10.0 % (w/w) EHMC promoted an increase in the preservation of in vitro SPF of 53.9% to 65.8 (0.1 % rutin) and 70.8 % (1.0% rutin). The DSC and TG curves of rutin showed changes promoted by the presence of BMBM and EHMC filters, indicating interaction between the flavonoid and filters. After 5760 J cm-2 of UV radiation the value of the trans/cis ratio for the EHMC filter added from the BMBM filter was increased from 5.5 ± 0.1 without addition of rutin, to 12.6 ± 0 4,with the addition of rutin. Qualitative analysis of the suppression of the singlet state indicated that one of the mechanisms involved in the photostabilization BMBM and EHMC filters is suppression of singlet excited state.The results reported in this study indicate that the addition of rutin in sunscreen formulations is a simple and effective way to increase the photostability of the combination of BMBM and EHMC. The addition of rutin in sunscreen formulations represents a promising strategy, for allied with the photostabilization action, observed in this study, this flavonoid has antioxidant and chelating properties of metals that can contribute to the development of broad-spectrum sunscreens formulations with increased safety and efficacy.

Validity Of Biology Items In 2006, 2007, And 2008 Student Selection Test In TurkeyKoyuncu, Fulya 01 February 2011 (has links) (PDF)
Student selection test in Turkey compose of two parts. The purpose of the first part is to assess students&rsquo / higher order thinking skills like analytical thinking, interpretation and reasoning about elementary school curriculum and 9th grade curricula objectives. On the other hand, second part of the test aims to assess students&rsquo / higher order thinking skills given in the high school curriculum.
The main aim of this thesis is to analyze to what extend 2006, 2007 and 2008 student selection tests biology items assess higher order cognitive skills. In accordance with this purpose, elementary and high school curriculum and the appropriateness of the questions in the student selection test with the educational objectives of the curriculum are examined. In addition, dimensions of 2006, 2007, and 2008 SST biology items are examined by Exploratory Component Analysis and Confirmatory Component Analysis techniques. The result of those analysis revealed that SST biology items mostly focus on remembering skill and fail to assess higher order thinking skills. Additionally, there is not any consistency among 2006, 2007, and 2008 SSTs biology items in terms of dimensions which means there is not any construct in biology subtests of SSTs.
The other aim of the present study is to identify how much academic and non-academic factors explain the biology achievement. While for academic factors reading comprehension, mathematics, physics, and chemistry achievements of students are used, age, gender, and school type are used for non-academic factors. Findings of the research revealed that academic factors, especially chemistry achievement, have significant affect on biology achievement. In terms of non-academic factors, graduating from selecting high school has important role for biology achievement. Additionally, older students and girls tend to have higher grades in biology.

Warlords in Africa : a comparative study of Jonas Savimbi and Farah AideedLawack, Marvin Sylvester 12 1900 (has links)
Thesis (MA (Political Science. International Studies))--Stellenbosch University, 2008. / Abstract:
The African continent has been riddled with conflict for many years. Angola and
Somalia are prime examples of countries having experienced protracted wars. During
those wars, warlords have played a definite role in perpetuating the fighting. The
thesis investigates warlordism in Africa. Specifically, it is a comparative analysis of
Jonas Savimbi of Angola and Farah Aideed of Somalia.
The thesis investigates the concept of warlords and uses the examples of Aideed and
Savimbi to illustrate the impact of warlords on the respective countries. The examples
of Aideed and Savimbi are further used to show that there are different ways to
becoming ultimately labelled as a warlord. The role of state weakness and ethnicity
will be investigated in the two cases. The discussion will highlight the points that state
weakness (i.e. lack of governmental functionality) and the use of ethnicity play a
profound role in the rise and survival of warlords. The case studies of Aideed and
Savimbi will emphasise the influence of state weakness and ethnicity in their
formation as warlords.
The concept of state weakness is defined and the thesis illustrates that there are
different levels of state weakness. The thesis compares Angola and Somalia, and
shows that Savimbi and Aideed acted under vastly different conditions as warlords.
Ethnicity is defined and linked to the idea that the effects of colonialism played a
profound role in creating ethnic divisions, enabling warlords such as Aideed and
Savimbi to use their ethnic backgrounds to mobilise followers to wage war. The thesis
investigates how Aideed and Savimbi maintained their military organisations. Their
ability to do so is related to both state weakness and ethnicity. State weakness and
ethnicity create conditions which are conducive to the emergence of warlords.
