JOHN CAGE: PREPARED PIANO (HAZIRLANMIŞ PİYANO)’NUN YİRMİNCİ YÜZYIL MÜZİĞİNDEKİ ETKİLERİ Özet Amerikalı Avangard besteci John Cage, 1930’lu yılların sonlarına doğru, birlikte çalıştığı Merce Cunningham, Bonnie Bird, Syvilla Fort gibi isimlerin dans koreografilerine eşlik etmek amacıyla Hazırlanmış Piyano için eserler yazmaya başladı. Hazırlanmış Piyano, tellerin üzerine veya arasına vida, cıvata, somun, lastik, silgi vb. malzemeler yerleştirilerek sesin karakterini ve tınısını değiştirebilme şansı elde edilen bir piyanodur. Bestecinin ilk hazırlanmış parçası olarak kabul edilen Bacchanale, küçük bir perküsyon grubunun tek bir enstrüman (hazırlanmış piyano) ile vurmalı bir orkestraya dönüştüğü eserdir. Bestecinin bir Hazırlanmış Piyano başyapıtı olarak bilinen eseri ise Sonatlar ve Int...

Description of the episeptal and interlaminar fascial tunnels for the superficial fibular nerve and its terminal branches.

KESİLMİŞ İNCİ | KURTOĞLU OLGUNUS ZELİHA

Purpose This study aimed to reveal the course of the superficial fibular nerve and its branches, whose entrapment may be responsible for anterior leg pain and is at risk in fasciotomies, according to the crural fascia laminae and the anterior inter muscular septum. Methods On the twenty cadaver legs, the location of the superficial fibular nerve and its branches, according to the crural fascia layers and anterior intermuscular septum, the course type in the tunnel, if any, and the superficialization pattern were defined. Results The number of cases in which the superficial fibular nerve and its branches traveled within a tunnel was found to be 15/20 (75%). The superficial fibular tunnel was defined as an “episeptal” and “interlaminar fascial” tunnel based on the nerve’s relati...

Phenolic acid and flavonoid diversity in four Eucalyptus species

Fazilet Özlem Albayrak | Yüksel Keleş

The economic importance of Eucalyptus trees is due to their rapid growth and high biomass productivity, as well as the beneficial chemical compounds found in their various tissues. Eucalyptus cultivation is common in the southern part of Turkey, especially in the coastal areas of the Mediterranean. In this study, phenolic acids and flavonoids were analyzed in methanol extracts leaf tissues of four eucalyptus species by HPLC. Fifteen different phenolic compounds were determined in the leaf tissues of the four Eucalyptus species examined. The highest total phenolic amounts were found in E. botryoides (160.56 mg g-1DW), followed by E. tereticornis (66.47 mg g⁻¹ DW) and E. citriodora (64.02 mg g⁻¹ DW). Twelve different compounds were determined in E. botryoides and E. citriodora species, 10 in...

Dişkaya, Orhan | Menken, Hamza

In the present work we consider the Jacobsthal and Jacobsthal- Lucas sequences with the Jacobsthal and Jacobsthal-Lucas subscripts sequences; that is, the numbers of the form Xn = JJn, Zn = Jjn, Yn = jjn and Tn = jJn. We obtain some identities and relations for the Jacobsthal and Jacobsthal- Lucas subscripts sequences. Also, we give recursive definitions for the sequences Xn, Zn, Yn and Tn.

Middle School Administrators’ Perceptions about Education's Contribution to Human Capital

The purpose of this study was to analyse the middle school administrators’ perceptions about education’s contribution to human capital in terms of the variables of gender, seniority, education level and the type of the school. The data were collected from 410 school administrators working in public and private middle school, which were in Mersin Province in the fall semester of 2018-2019 academic year. It was found out that there was a significant difference among the school administrators’ perceptions in terms of the variables of gender, seniority, education level and the type of the school.

Similarity, proximity, approximation, equivalence and identity relationships constituted between multiple concepts provide direct or indirect comparison of concepts, positioning relative to each other, making precise or predictive evaluations about them and transmitting various features in a more concrete way. These forms of expression based on similarities between concepts in terms of quality or quantity, relative and gradual proximity, equivalences, identities are used for an effective language that is strong in association and concretization. So language users actualise the meaning relations by taking advantage of the some linguistic features and the possibilities of expression. In this context, many linguistic and cultural components play an active role, especially lexical, morphologic...

Comparative degradation of 5-fluorouracil in aqueous solution by using H2O2-modified subcritical water, photocatalytic oxidation and electro-Fenton processes

Gözmen, Belgin

This study investigated the degradation of the antineoplastic agent 5-fluorouracil (5-FU) widely applied to treat different cancers using different advanced oxidation processes such as electro-Fenton (EF), photocatalysis with TiO2, and H2O2-modified subcritical water oxidation. The treatment with the EF process was the most efficient compared to others. Interestingly, in the EF process, the oxidative degradation of 5-FU behaved differently depending on the anode used. At low currents (20 and 40 mA), Pt and DSA anodes performed better than BDD and Ti4O7 anodes. In contrast, at the higher current of 120 mA, the production of heterogeneous hydroxyl radicals (M(• OH)) became important and contributed significantly to the oxidation of 5-FU in addition to homogeneous • OH generated in th...

Application of the central composite design to mineralization of olive mill wastewater by the electro/FeII/persulfate oxidation method

Gözmen, Belgin | Görmez, Özkan | Yabalak, Erdal

The olive mill wastewater is a major environmental problem, which is waiting for effective treatment. In this study, the mineralization of olive mill wastewater was investigated using the electro/FeII/persulfate process. The central composite design was utilized to examine the effect of each experimental variables (concentration of persulphate and FeII, treatment time and constant current) on the mineralization of olive mill wastewater. The optimum chemical oxygen demand removal percentage was obtained as 71.2% where the reaction conditions were 200 mA current, 250 mM persulphate, 25 mM FeII, and 6 h reaction time. In addition, the maximum percentage of total phenolic removal and the energy consumption were 88% and 4.50 kWh/kgCOD, respectively, which were obtained at the same reaction ...

Electrocoagulation and nanofiltration integrated process application in purification of bilge water using response surface methodology

Gözmen, Belgin | Dizge, Nadir | Turabik, Meral | Gülsen, H. Elif

Marine pollution has been considered an increasing problem because of the increase in sea transportation day by day. Therefore, a large volume of bilge water which contains petroleum, oil and hydrocarbons in high concentrations is generated from all types of ships. In this study, treatment of bilge water by electrocoagulation/electroflotation and nanofiltration integrated process is investigated as a function of voltage, time, and initial pH with aluminum electrode as both anode and cathode. Moreover, a commercial NF270 flat-sheet membrane was also used for further purification. Box–Behnken design combined with response surface methodology was used to study the response pattern and determine the optimum conditions for maximum chemical oxygen demand (COD) removal and minimum metal ion conte...

ÖZER, Selmin, AYAS, Deniz

In this study, the effects of the age and individual size on total lipid content, fatty acids and elemental composition of Nemipterus randalli caught from the Mersin Bay were determined. The lipid content of all age groups was found at similar levels. However, the highest lipid level was determined in the 3+ age group (2.85%) while the lowest level was found in the 2+ age group (2.75%). Dominant fatty acids for each age group of N. randalli are palmitic acid (C16:0), stearic acid (C18:0), vaccenic acid (C18:1n7c), cetoleic acid (C22:1n11), eicosapentaenoic acid (EPA, C20:5n3), and docosahexaenoic acid (DHA, C22:6n3). The highest palmitic acid level was found in 3+ age group (20.45%) whereas the highest stearic acid level was found in the 2+ age group (15.00%). The highest vaccenic acid lev...
