Tuba Yilmaz(Tuba Yilmaz ) 전남대학교 교육문제연구소 2023 New Horizons of Educational Research Vol.3 No.1

The Quechua language, spoken by indigenous Quechuans, faced endangerment due to the widespread use of Spanish. This paper explored the language revitalization policies for Quechua language in South American countries, particularly Peru, Bolivia, and Ecuador. The paper began by presenting a concise overview of Quechua and the Quechuan community, elucidating the factors contributing to Quechua's endangered status and the prevalence of Spanish monolingualism. Subsequently, it delved into an exploration of language revitalization policies and challenges within each country, framed by corpus planning, status planning, acquisition planning, and prestige planning. The paper concluded with a discussion on the outcomes of Quechua revitalization efforts. This paper offered valuable insights for countries adopting a 'language as a resource approach,' and particularly those endeavoring to implement additive policies for their extinct, endangered, or threatened languages.

Demirci, Nilgun Yilmaz,Ulger, Sukran,Yilmaz, Ulku,Aydogdu, Koray,Yilmaz, Aydin,Erdogan, Yurdanur Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.11

Background: The incidence of lung cancer increases with age. Approximately 50% of non-small cell lung cancer (NSCLC) patients are over 70 years old. Because of the increasing elderly population, treatment approaches in this age group continue to be studied similar to groups of young people. Materials and Methods: In the current study, 26 patients who underwent radical surgery and adjuvan chemoradiation at Ataturk Chest Diseases and Chest Surgery Training and Research Hospital were evaluated retrospectively. Results: Of 21 patients (81%) were male and the average age was 74.4. Lobectomy was performed in 18 cases, pneumonectomy in 3, sleeve lobectomy in 3 and bilobectomy in 2. There was no perioperative or early period mortality. Overall survival was 24.5 months. Conclusions: From our study, lung cancer surgery and adjuvant therapy can be performed safely with low morbidity in the elderly.

Towards a better understanding of detection properties of different types of plastic scintillator crystals using physical detector and MCNPX code

Yilmaz Ayberk,Alan Hatice Yilmaz,Susam Lidya Amon,Akkus Baki,ALMisned Ghada,Ilhan Taha Batuhan,Tekin H.O. 한국원자력학회 2022 Nuclear Engineering and Technology Vol.54 No.12

The purpose of this comprehensive research is to observe the impact of scintillator crystal type on entire detection process. For this aim, MCNPX (version 2.6.0) is used for designing of a physical plastic scintillation detector available in our laboratory. The modelled detector structure is validated using previous studies in the literature. Next, different types of plastic scintillation crystals were assessed in the same geometry. Several fundamental detector properties are determined for six different plastic scintillation crystals. Additionally, the deposited energy quantities were computed using the MCNPX code. Although six scintillation crystals have comparable compositions, the findings clearly indicate that the crystal composed of PVT 80% þ PPO 20% has superior counting and detecting characteristics when compared to the other crystals investigated. Moreover, it is observed that the highest deposited energy amount, which is a result of the highest collision number in the crystal volume, corresponds to a PVT 80% þ PPO 20% crystal. Despite the fact that plastic detector crystals have similar chemical structures, this study found that performing advanced Monte Carlo simulations on the detection discrepancies within the structures can aid in the development of the most effective spectroscopy procedures by ensuring maximum efficiency prior to and during use.

Investigation of properties of boehmitic sol coated graphite added alumina-low cement castables

Suat Yilmaz,Ersan Yilmaz 한양대학교 세라믹연구소 2010 Journal of Ceramic Processing Research Vol.11 No.1

In this study, benefiting from the low wettability of graphite, various amounts were added to low cement alumina castables to investigate the resistance of refractories to slag corrosion. For this purpose, typically flake graphite was coated with alumina by a sol-gel method and then added to a mixture of the refractory in various amounts. After the physicomechanical investigation, steel ladle slag with a basicity ratio of 2.29 was charged into the crucibles which were prepared according to DIN 51069 standard. After the heat treatment, samples were cut vertically for investigation. For macroscopic analysis, images taken from the slag-refractory surfaces were digitized and subjected to image analyses to investigate the penetration of the slag. Microscopic analyses were carried out with SEM-EDS to determine the elemental dispersion at the refractory-slag interaction zone. Experimental results indicate that the alumina coated graphite addition give improved slag corrosion resistance of alumina castables.

Filiz Yilmaz,Orkun Ilgen,Alper Mankan,Bayram Yilmaz,Sefa Kurt The Korean Society for Reproductive Medicine 2023 Clinical and Experimental Reproductive Medicine Vol.50 No.4

Objective: Ovarian torsion is a gynecological disorder that causes ischemia-reperfusion injuries in the ovary. Our study investigated berberine's short- and long-term effects on ovarian ischemia-reperfusion injuries. Methods: This study included 28 Wistar albino female rats weighing 180 to 220 g, which were divided into four groups: sham (S), torsion/detorsion (T/D), torsion/ detorsion+single dose berberine (T/D+Bb), and torsion/detorsion+15 days berberine (T/D+15Bb). The torsion and detorsion model was applied in all non-sham groups. In the T/D+Bb group, a single dose of berberine was administered, while in the T/D+15Bb group, berberine was administered over a period of 15 days. After the rats were euthanized, their ovaries were excised. The left ovaries were used for histopathologic evaluation, which included ovarian injury scoring and follicle count, while the right ovaries were used for biochemical analyses (tissue transforming growth factor-β [TGF-β] and alpha-smooth muscle actin [α-SMA] levels). Results: The histopathologic evaluation scores for the ovaries were significantly lower in the T/D+B group (p<0.05) and the T/D+15B group (p<0.005) than in the T/D group. The follicle counts in the T/D group were lower than those in both the sham and treated groups (p<0.005). The TGF-β levels were significantly lower in the T/D+15B group (p<0.005), whereas the α-SMA levels did not show a significant difference. Conclusion: Both short- and long-term berberine use could potentially have therapeutic effects on ovarian torsion. Long-term berberine use exhibited anti-inflammatory effects by reducing TGF-β levels, thereby preventing ischemia-reperfusion injuries. Therefore, we suggest that long-term berberine use could be beneficial for ovarian torsion.

The Investigation of Treatment of Pistachio Processing Industrial Wastewater by Electrochemical Methods in Terms of Chemical Oxygen Demand and Total Phenol Removal

Alper Erdem Yilmaz,Baybars Ali Fil,Murat Tolga Yilmaz,Serkan Bayar,Zuhal Koksal The Korean Electrochemical Society 2024 Journal of electrochemical science and technology Vol.15 No.1

This work aims to investigate the efficiency of electrocoagulation (EC) of pistachio processing industrial wastewater (PPIW) using the continuous EC process. The tubular reactor made of stainless steel with an internal diameter of 60 mm was used as a cathode electrode. The effect of some parameters was examined on the removal of chemical oxygen demand (COD) and total phenols (TP) removal efficiency. The influences of the initial pH of wastewater (from 4 to 8), flow rate (from 25 to 125 mL/min), current density (from 7 to 21 mA/cm²), and supporting electrolyte type (NaCl, NaNO₃, and Na₂SO₄), supporting electrolyte concentration (from 10 to 100 mg/L NaCl) on removal efficiency were investigated to determine the best experimental conditions. The examination of the physico-chemical parameters during the EC treatment showed that the best removal efficiency was obtained under conditions where the flow rate was 25 mL/min (20 min reaction time), the pH value was 5.2, and the current density was 21 mA/cm² has set. Under these experimental conditions, COD and TP removal efficiency were found to be 75% and 97%, respectively, while energy consumption was 18.5 kW h/m³. The study results show that the EC can be applied to PPIW pre-treatment.

Yilmaz Simsek 장전수학회 2016 Advanced Studies in Contemporary Mathematics Vol.26 No.3

The aim of this paper is to modify the generating functions for the Daehee numbers and polynomials and also for the Bernoulli numbers and polynomials of the second kind. By using these functions, we give relations between the λ-Bernoulli numbers and polynomials, Apostol type Daehee numbers and polynomials, the λ-Stirling numbers of the second kind and λ-Bernoulli numbers and polynomials of the second kind. Moreover, by using the p-adic Volkenborn integral, we derive combinatorial sums associated with the Apostol type Daehee numbers and polynomials.

ON S-CLOSED SUBMODULES

Yilmaz Durugun,Salahattin Ozdemir 대한수학회 2017 대한수학회지 Vol.54 No.4

A submodule $N$ of a module $M$ is called $\mathcal{S}$-closed (in $M$) if $M/N$ is nonsingular. It is well-known that the class $\closed$ of short exact sequences determined by closed submodules is a proper class in the sense of Buchsbaum. However, the class $\mathcal{S}-\closed$ of short exact sequences determined by $\mathcal{S}$-closed submodules need not be a proper class. In the first part of the paper, we describe the smallest proper class $\langle\mathcal{S}-\closed\rangle$ containing $\mathcal{S}-\closed$ in terms of $\mathcal{S}$-closed submodules. We show that this class coincides with the proper classes projectively generated by Goldie torsion modules and coprojectively generated by nonsingular modules. Moreover, for a right nonsingular ring $R$, it coincides with the proper class generated by neat submodules if and only if $R$ is a right SI-ring. In abelian groups, the elements of this class are exactly torsion-splitting. In the second part, coprojective modules of this class which we call \emph{ec-flat} modules are also investigated. We prove that injective modules are ec-flat if and only if each injective hull of a Goldie torsion module is projective if and only if every Goldie torsion module embeds in a projective module. For a left Noetherian right nonsingular ring $R$ of which the identity element is a sum of orthogonal primitive idempotents, we prove that the class $\langle\mathcal{S}-\closed\rangle $ coincides with the class of pure-exact sequences of modules if and only if $R$ is a two-sided hereditary, two-sided $CS$-ring and every singular right module is a direct sum of finitely presented modules.

We define Apostol-type Daehee numbers and polynomials of higher order. We derive some properties, relations and identities on these numbers and polynomials. Finally, we give some applications of the p-adic Volkenborn integral including the special numbers and polynomials. We give some remarks and observations associated with the Bernoulli numbers, the Euler numbers, the Daehee numbers, and the Changhee numbers.
