What are the lessons that can be learned from Turkey's transnational operational police cooperation experiences?
No full textAlthough transnational organized crime and terrorism are not new, they are becoming increasingly intersected. Their combined activities threaten today‘s globalized world, making police collaboration across national borders more crucial than ever. As a consequence, bilateral and multilateral collaborations among national law enforcement agencies are increasing, and multinational police organizations are expanding their operations in order to cope more effectively with transnational crimes and terror. This dissertation explores the parameters of operational police cooperation across borders, by examining Turkey‘s policing relationships with other states as well as with international police cooperation organizations. Understanding how trans-border police cooperation works in practice, including what enhances or hinders such cooperation at the grassroots level, is the main objective of this study. The research methodology involved interviews with police professionals who had working experiences in these areas.Ph.D.Includes bibliographical referencesIncludes vitaby Huseyin Or

Is Per Capita Real GDP Stationary in the OECD Countries? Evidence from a Panel Unit Root Test
No full textThis paper examines the stationarity of real GDP per capita for 27 OECD countries during the period 1950 to 2004. Using ADF unit root test on single time series, it is found that real GDP per capita series of most OECD countries have unit root. This outcome, however, might be due to the generally low power of this test. The aim of this paper is to reconsider this issue by exploiting the extra information provided by the combination of the time-series and cross-sectional data and the subsequent power advantages of panel data unit root tests. We apply the test advocated by Im, Pesaran and Shin (1997). The results overwhelmingly indicate that real GDP per capita series among OECD countries are nonstationary.Real GDP per capita, Stationary, Panel Unit root tests, OECD
A POETIC NASIHAT-NAME WRITTEN FOR MURAD IV: MIFTAH-I CENNET OF QADIRI HUSEYIN
No full textMany nasihat-names have been written with the aim of improving the individual and society in Turkish Islamic Literature field. These works can be written for the general community, they are also written for a spesific part of the society such as women, children, brethren, state administrators. The work named Miftah-i Cennet of Qadiri Huseyin was written for Sultan IV. Murad, one of the 17th century Ottoman sultans. The aim of the work is to guide the sultan who ascended the throne at the age of just a child. Sultan is the collocutor of the advices given to lead him to the happiness of the world and the hereafter. In this study, Miftah-i Cennet that was written for Sultan IV. Murad and has the feature of a poetic nasihat-name will be introduced. In the first part of the study, which consists of two parts, the life and works of Qadiri Huseyin, the author of the work, which does not have any information about his life in the biographical sources, will be mentioned. In addition, the opinions that the person known as Muhyiddin-i Qadiri may be the same person as Qadiri Huseyin will be presented. In the second part, the copies of Miftah-i Cennet which is the subject of our study will be introduced and general information about the content of the work will be given

Is volume index of gdp per capita stationary in oecd countries? panel stationary tests with structural breaks
No full textThe purpose of this paper is to investigate whether volume index of GDP per capita is stationary for 24 OECD countries during the period 1970 to 2006. We utilize a panel stationary tests that allow for multiple structural breaks, developed by Carrion-i-Silvestre et al. (2005). The empirical findings are threefold: (1) when we employ univariate unit tests, such as ADF and KPSS without structural breaks, we hardly find evidence of I(0) stationarity, except for Switzerland (2) when we employ KPSS stationarity test with multiple structural breaks, we find evidence of I(0) stationarity for 22 out of 24 countries and (3) when we employ KPSS panel I(0) stationarity test with multiple structural breaks and the assumption of cross-section dependence, we find significant evidence of panel I(0) stationarity of per capita GDP for these OECD countries. The findings of this paper have implications for policymaking and econometric modeling for these 24 OECD countries.Volume Index of GDP per Capita Panel Stationary Tests with Structural Breaks OECD Countries

Grayanotoxin-III Detection and Antioxidant Activity of Mad Honey
No full textSahin, Huseyin/0000-0002-6018-1494WOS: 000359160500006Mad honey is a complex mixture of numerous chemicals produced by honeybees from Rhododendron flowers. Consumption of mad honey leads to diarrhea, perspiration, dizziness, changes in consciousness, syncope, diplopia, as well as blurred vision, hypotension, and bradycardia due to the presence of grayanotoxins (GTXs). Therefore, it is important to detect the level grayanotoxins in mad honey. Besides its toxicity, mad honey also has antioxidant activity. This study was designed to determine the level of grayanotoxin-III toxin and antioxidant activity of ten different mad honey samples collected from the Black Sea region of Turkey. Liquid chromatography-tandem mass spectrometry was used for the quantitation of grayanotoxin-III. Antioxidant activity was evaluated using total phenolic contents, total ferric reducing antioxidant power, scavenging of 2,2-diphenyl-1-picrylhydrazyl and 3-(2-pyridyl)-5, 6-diphenyl-1,2,4-triazine-4',4''-disulfonic acid radicals. Quantities of grayanotoxin-III levels ranged from 68.754 to 0.701 mu g grayanotoxin-III/g honey. Mad honey MH7 from Artvin/Hopa had the highest grayanotoxin-III level. Although there were varying levels of grayanotoxin-III, mad honey samples were outstanding in terms of antioxidant activity. MH3 had the highest antioxidant potential. Although toxicity effect comprises, a metered dose of mad honey might also be explored as a potential source in clinical trials due to high bioactivity levels.TAGEMGida Tarim Ve Hayvancilik Bakanligi [AR-GE/15]; Tubitak BidebTurkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK)The study was supported by TAGEM AR-GE/15, and author Huseyin Sahin was supported by a grant from the research fund of Tubitak Bideb for his Ph.D. research
Nanoemulsions: formation, properties and applications
No full textNanoemulsions are kinetically stable liquid-in-liquid dispersions with droplet sizes on the order of 100 nm. Their small size leads to useful properties such as high surface area per unit volume, robust stability, optically transparent appearance, and tunable rheology. Nanoemulsions are finding application in diverse areas such as drug delivery, food, cosmetics, pharmaceuticals, and material synthesis. Additionally, they serve as model systems to understand nanoscale colloidal dispersions. High and low energy methods are used to prepare nanoemulsions, including high pressure homogenization, ultrasonication, phase inversion temperature and emulsion inversion point, as well as recently developed approaches such as bubble bursting method. In this review article, we summarize the major methods to prepare nanoemulsions, theories to predict droplet size, physical conditions and chemical additives which affect droplet stability, and recent applications.Eni S.p.A
Machine learning predicted magnetic entropy change using chemical descriptors across a large compositional landscape
No full textMagnetocaloric refrigeration has drawn considerable attention in the last few decades as it can positively disrupt the current cooling technology. Most research efforts focus on developing new magnetic materials in the laboratory by trial and error. Here we report a materials dataset developed using past experimental work comprising several important magnetocaloric material classes such as La(Fe,Si/Al)13, heusler alloys, manganites, Gd5(Si,Ge)4 family, rare-earth and metallic glasses as well as Laves phase compounds with their reported magnetic entropy changes, -ΔSM(T,H). Notable linear and non-linear machine learning models are implemented to predict the -ΔSM(T,H) of materials. Our analyses indicate that the Random Forest model outperforms the others with R2 of 0.82. We then use this model to screen a large magnetic materials database with nearly 40,000 compounds to identify potential new magnetocaloric materials operating near room temperature. MnGa2Sb2, CrGa2Sb2, SbSCl0.1I0.9, Sm3Te4, LaRhSn, SbSI, Tl0.58Rb0.42Fe1.72Se2, Cs0.86Fe1.66Se2, La2.1MnGe2.2 are some of the newly predicted compounds that could yield large magnetocaloric cooling performance."This article is published as Ucar, Huseyin, Durga Paudyal, and Kamal Choudhary.
