Bu çalışmada İbrahim Aczî Kendî'nin hayatı incelenmiş, Devr-i Zaman adlı eserinde bulunan 360 rubâînin son 180 tanesi çalışılmıştır. Her bir rubâînin Farsça ana metinleri bilgisayar ortamına aktarılmış, bazen sadece tercüme, bazen de çeşitli açıklamalar içeren Osmanlı Türkçesiyle yazılan kısımlar ise latin harfleriyle aktarılmıştır. İbrahim Aczî Kendî, bu çalışmada ele alınan rubâîlerinde, genellikle ilahi aşk, toplumsal ahlâk, zamandan şikâyet, riya ve kibirden uzak durmanın gerekliliği gibi birçok konuya değinmiştir.İbrahim Aczî Kendî who lived the years between 1881 and 1965 in Konya is an important poet, a journalist, an investigate author, a mystic and a folklorist who raised by Konya in 20th century. İbrahim Aczî Kendi, worked as a tutor in Konya, improved himself by learning Arabian and Persian, prepared books about mysticism, literature and history. Devr-i zaman, which is written by İbrahim Aczî Kendî by himself and whose only transcript is registered with the number 104657/1 in Yusuf Ağa Library, is made of 360 Persian rubaies and their explanation which is written in Ottoman Turkish. In this study İbrahim Aczî Kendî's life and last 180 of 360 Persian rubaies are studied. Each of rubaies' Persian main texts are transferred to electronic environment. Parts that sometimes include translation, sometimes also include various types of explanations written Ottoman Turkish are transferred with Latin letters. İbrahim Aczî Kendî, rubaies that handled in this study, touches on many topics, such as sociel ethics, complaints about today's youht, hypocrisy and staying away from and arrogance
External interventions and the duration of civil wars
No full textThe authors combine an empirical model of external intervention, with a theoretical model of civil war duration. Their empirical model of intervention allows them to analyze civil war duration, using"expected"rather than"actual"external intervention as an explanatory variable in the duration model. Unlike previous studies, they find that external intervention is positively associated with the duration of civil war. They distinguish partial third-party interventions that extend the length of war, from multilateral"peace"operations, which have a mandate to restore peace without taking sides - and which typically take place at war's end, or at least when both sides have agreed to a cease-fire. In a future paper, the authors will examine whether partial third-party interventions - whatever their effect on a war's duration - increase the risk of war's recurrence. If that proves true, then even if interventions reduce the length of civil war, they may do so at the cost of further destabilizing the political system, and sowing the seeds of future rebellion.Children and Youth,Peace&Peacekeeping,Post Conflict Reconstruction,Post Conflict Reconstruction,International Affairs,Post Conflict Reconstruction,Social Conflict and Violence,Peace&Peacekeeping,Post Conflict Reconstruction,International Affairs
The role of Na surface species on oxygen charge transfer in the Pt/YSZ system
No full textThe role of sodium surface species in the modification of a platinum (Pt) catalyst film supported on 8 mol% yttria-stabilised-zirconia (YSZ) was investigated under a flow of 20 kPa oxygen at 400 °C. Cyclic and linear sweep voltammetry were used to investigate the kinetics of the oxygen charge transfer reaction. The Pt/YSZ systems of both ‘clean’ and variable-coverage sodium-modified catalyst surfaces were also characterised using SEM, XPS and work function measurements using the Kelvin probe technique.Samples with sodium coverage from 0.5 to 100% were used. It was found that sodium addition modifies the binding energy of oxygen onto the catalyst surface. Cyclic voltammetry experiments showed that higher overpotentials were required for oxygen reduction with increasing sodium coverage. In addition, sodium was found to modify oxygen storage and/or adsorption and diffusion increasing current densities at higher cathodic overpotential. Ex situ XPS measurements showed the presence of sodium hydroxide, carbonate and/or oxide species on the catalyst surface, while the Kelvin probe technique showed a decrease of approximately 250 meV in the work function of samples with more than 50% sodium coverage (compared to a nominally ‘clean’ sample)
The role of low coverage sodium surface species on electrochemical promotion in a Pt/YSZ system
No full textLink to publisher's homepage at http://www.journals.elsevier.comThe effect of sodium-modification on the catalyst and electrocatalytic properties of a platinum catalyst supported on a YSZ solid electrolyte was studied. Increasing the sodium coverage on the catalyst surface appears to block some of the three-phase boundary (tpb) sites and reduces the rate of the charge transfer reaction. The promotion of the platinum surface reaction (ethylene oxidation) seems to a first approximation to be a function of the rate of oxygen supply or removal to or from the surface irrespective of whether this is contaminated by sodium or not (samples with sodium contamination require a higher overpotential to achieve the same current density as a clean sample because of poisoning in the tpb). At high negative polarisations (oxygen removed from the surface) the sodium contaminated samples show a significant increase in rate, possibly due to the decomposition of e.g. sodium hydroxides and carbonates
Influence of impurities and catalyst surface characteristics on the oxygen charge transfer reaction in the Pt/YSZ system
No full textLink to publisher's homepage at http://www.journals.elsevier.comSpillover processes (i.e. the migration of ionic species from the support to the catalyst and vice versa) are known to play a very important role in catalysis and electrocatalysis. These spillover processes can be influenced by impurities (pre-existing on the catalyst surface) and by the catalyst morphology that may differ as a result of the differences in catalyst manufacturing processes. This work investigates the influence of impurities present in three commercial platinum (Pt) precursors. The resulting platinum films studied here were supported on yttria-stabilised-zirconia (YSZ). It was found that the three different catalyst films contained a range of impurities (determined by ICP-OES) that appear to affect the oxygen charge transfer reaction as studied by cyclic voltammetry (CV)
Morphological and grammatical study of the fuctional derived nouns in the six anthologies by Sheikh Ibrahim Inyas / Ibrahim Shaaban
No full textThis research is a morphological, grammatical and analytical study on the multiplicity of the
scale of five derived nouns and their formulas as used in the six anthologies (dawawin) of
Senegalese Sheikh Ibrahim Inyas al-Kaulakhi, based on the chosen rulings, methods and context
used by the author of the six collections. The research focuses and discusses on the subject
noun, the accusative noun, the hyperbolic participles, the attributive participle,
comparative/superlative adjective, and their scales and formulas, both standard and nonstandard,
and the usage of their multiple meanings according to the methods employed in these
six dawawin, including infinitive and augmented noun of three or four lettered origin, with
grammatical rulings associated with alif and lam (al), as selected or chosen according to the
usage of Sheikh Ibrahim Inyas al-Kaulakhi. In order to find out the context of morphological and
grammatical methods, analyses were made that acquaint readers with the taste of Sheikh
Ibrahim's ability in applying morphological and grammatical rules. Through extrapolation, the
morphological and syntactic source of each derivative was separately traced in those six
dawawin. In reviewing the morphological and syntactic language of those derivatives, books and
the theories of ancient and modern linguists, according to consensus and contrast, were used in
shedding light on each derived noun by studying the ancient morphological and syntactic
sources according to the information and theories derived therefrom and made analysis
thereon. In this regard, a morphological or grammatical context was established using a
qualitative rather than quantitative approach based on which the research was conducted and
its structure, sections and chapters arranged accordingly, with clarification and detailed
analyses. Findings of this research have established the functioning of morphological structure
and scales of the five derived nouns as well as the semantic meaning, application and usage of
augmented derived nouns as dealt with in their grammatical rulings associated with the Arabic
definite article - alif and lam (al), to enable them function in the past, present and future tenses,
and what not. The research concluded with a revelation which is indicative of Sheikh Ibrahim
Inyas’ ability and mastery of morphological scales and grammatical expertise as though he lived
with and learnt from Khalil, Sibawayh, Ibn Jinni and Asma'i and their ilk
