The Impact On Students Preferences Of Promotional Mediums Of Universities: The Sample Of Karatay University Students

BÜYÜKDOĞAN, Birol | GEDİK, HASAN

Owing to oppression of globalization and communication systems, the institutional publicity activities became more important now than 10 years ago. For the time being, 193 universities stand/take place in Turkey. Universities as a public institution, reserve more share to websites, social media and the other promotional formats. The aim of this research is to clear up the factors which affect student’s preferences. In this research, 919Karatay University’s students are subjected to a survey. According to results, web sites and the social media pages are the most preferred formats of publicity ...Daha fazlası

Kaybolmuş ve Kaybolmaya Yüz Tutmuş Meslekler

ÇINAR, Kerim

Yeni İpek Yolu özel sayısı Konya kitabı XV'te, geçmişte şehrin ekonomisinde önemli bir yeri olan "Unutulmuş veya unutulmaya yüz tutmuş sanat-zana­at ve meslekler'' konusu ele alınmıştır. Bu amaçla ta­rih öncesi çağlardan günümüze Anadolu'nun önemli bir ticaret ve sanat şehri Konya kentinde bu konuya ilişkin önemli örnekler bulunmaktadır. İlk ev yapımı, ahşap oyma, dokuma ustaları Çatalhöyük'te (M.Ö. 8500-4500) ortaçağ çıkmıştır. Konya çarşısı Selçuklu ve Osmanlı devirlerinde en büyük ticaret merkezi olma özelliği taşımıştır.

Kayıp Krizi Nasıl Fırsat Krizine Dönüştü? Türkiye, ABD ve AB Ülkelerinden Seçilmiş İşletmeler Örneği

ÇAKIR, Beyhan Özgü | ÇELİK, Adnan

Organizasyonları birer sosyo-teknik sistem hatta birer canlı organizma gibi görecek olursak, son yıllarda yaşanan hızlı değişimleri kavramak, sorunları tespit etmek, çözüm yolları bulmak, bu yollardan en makulünü denemek ve sorunları tamamen ortadan kaldırmak için işletmelerin çok da fazla vakti bulunmamaktadır. Durumsallık yaklaşımının ışığı altında işletmeler birer açık sistem olmakla birlikte çevreleriyle sürekli iletişim halindelerdir ve bunun gereği olarak etkileşim ve değişim kaçınılmaz olmakta ve kimi zaman da bu etkileşimin sonucu kriz gibi işletme için hayati sorunlara yol açabilmekte ...Daha fazlası

Centrality dependence of particle production in p–Pb collisions at √sNN= 5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

We report measurements of the primary charged-particle pseudorapidity density and transverse momentum distributions in p-Pb collisions at sNN=5.02TeV and investigate their correlation with experimental observables sensitive to the centrality of the collision. Centrality classes are defined by using different event-activity estimators, i.e., charged-particle multiplicities measured in three different pseudorapidity regions as well as the energy measured at beam rapidity (zero degree). The procedures to determine the centrality, quantified by the number of participants (Npart) or the number of n ...Daha fazlası

Measurement of charged jet production cross sections and nuclear modification in p–Pb collisions at √ sNN = 5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

Charged jet production cross sections in p-Pb collisions at root s(NN) = 5.02 TeV measured with the ALICE detector at the LHC are presented. Using the anti-k(T) algorithm, jets have been reconstructed in the central rapidity region from charged particles with resolution parameters R = 0.2 and R = 0.4. The reconstructed jets have been corrected for detector effects and the underlying event background. To calculate the nuclear modification factor, R-pPb, of charged jets in p-Pb collisions, a pp reference was constructed by scaling previously measured charged jet spectra at root s = 7 TeV. In the ...Daha fazlası

Impact of repeaters on the performance of indoor visible light communications

KIZILIRMAK, Refik Çağlar

In this study, we examine the performance of fixed gain amplify-and-forward repeaters for visible light communication (VLC) systems. We present the wireless optical channel model for VLC with the repeater and we evaluate the bit-error-rate (BER) performance for pulse-position modulation over the multipath channel with additive white Gaussian noise. The results reveal that when a repeater is placed, both the BER and the illuminance performance can be improved at any location in a typical office space. The benefit of VLC repeaters is also discussed when the channel from the source to the destina ...Daha fazlası

A Novel Architecture Based On A Conducting Polymer And Calixarene Derivative: İts Synthesis And Biosensor Construction

GÖKOĞLAN, Tuğba Ceren | SÖYLEMEZ, Saniye | KESİK, Melis | ÜNAY, Hande | SAYIN, Serkan | YILDIZ, Hüseyin Bekir | ÇIRPAN, Ali | TOPPARE, Levent

In this study, a novel amperometric glucose biosensor based on a selenium comprising conducting polymer and calixarene was developed. Firstly, poly(2-(2-octyldodecyl)-4,7-di(selenoph-2-yl)-2H-benzo[d][1,2,3]triazole), poly((SBTz)) was electrodeposited onto a graphite electrode by an electropolymerization technique. Then, a newly synthesized calixarene and gold nanoparticle (AuNP) mixture was used for the improvement of biosensor characteristics. GOx, as a model enzyme was immobilized on the modified electrode surface. The constructed surface serves as a sufficient immobilization platform for t ...Daha fazlası

Calixarene assembly with enhanced photocurrents using P(SNS-NH2)/CdS nanoparticle structure modified Au electrode systems

SAYIN, Serkan | AZAK, Hacer | YILDIZ, Hüseyin Bekir | ÇAMURLU, Pınar | UYSAL AKKUŞ, Gülderen | TOPPARE, Lale | ERSÖZ, Mustafa

Two novel calix[n]arene-adorned gold electrodes producing high photocurrent intensities were successfully constructed by embedding gold electrode surfaces with both P(4-(2,5-di(thiophen-2-yl)-1H-pyrrol-1-yl)benzenamine) conducting polymer and 4-mercaptoboronic acid-functionalized semiconductor CdS nanoparticles to facilitate the binding of calix[n]arene sulfonic acids with nanoparticles. This structure enabled an electron transfer cascade that both induced effective charge separation and efficiently generated photocurrent. The prepared electrodes were used to generate photocurrent by relying o ...Daha fazlası

Deneysel diyabette insülinin böbrek dokusu üzerine etkileri

CÜCE, Gökhan | ŞEFLEK, Hatice Nur | ÇETİNKAYA, Seda | AKTAN, Tahsin Murat | DUMAN, Selçuk | YILMAZ, Mehmet Tuğrul | BÜYÜKMUMCU, Mustafa

We investigated the effect of insulin therapy on renal damage in experimentally induced diabetic rats. In this study 21 male Sprague-Dawley rats were used. The rats were divided into 3 groups,diabetic (n = 7) , diabetic + insulin therapy (n = 7), and control (n = 7). Statistically significant differences were identified in the evaluation of histopathological findings between all groups. Histopathological findings showed an expansion of the mesangial matrix, a reduction in the range of Bowman’s space, disintegration of tubular epithelium, distortion and loss of brush-edge epithelial tubules, an ...Daha fazlası

Coherent ψ(2S) photo-production in ultra-peripheral Pb–Pb collisions at √sNN = 2.76 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

We have performed the first measurement of the coherent ψ(2S) photo-production cross section in ultra- peripheral Pb–Pb collisions at the LHC. This charmonium excited state is reconstructed via the ψ(2S)→ l+l− and ψ(2S)→J/ψπ+π− decays, where the J/ψ decays into two leptons. The analysis is based on an event sample corresponding to an integrated luminosity of about 22 μb−1. The cross section for coherent ψ (2S) production in the rapidity interval −0.9 < y < 0.9 is dσ coh /d y = 0.83 ± 0.19 ����� stat + syst ����� mb. The ψ (2S) ψ (2S) to J/ψ coherent cross section ratio is 0.34+0.08 (stat + sys ...Daha fazlası

The expression of apoptotic markers in the aortic medial layer of diabetic rats and the effects of N. sativa L. seed oil on the expression of these markers were investigated in this study. Methods: Four-month-old adult female Wistar rats (n=21) were divided into 3 groups: Group 1, control; Group 2, diabetes and Group 3, diabetes+N. sativa L. seed oil. Group 3 received 0.2 mg/kg/day N. sativa L. seed (black cumin) oil intraperiton ...Daha fazlası
