- Derleme MakaleAçık Erişim2019FCC Physics Opportunities: Future Circular Collider Conceptual Design Report Volume 1
Abada, A.; Abbrescia, M.; AbdusSalam, S.S.; Abdyukhanov, I.; Fernandez, J. Abelleira; Abramov, A.; Aburaia, M.; Acar, A.O.; Adzic, P.R.; Agrawal, P.
We review the physics opportunities of the Future Circular Collider, covering its e+e-, pp, ep and heavy ion programmes. We describe the measurement capabilities of each FCC component, addressing the study of electroweak, Higgs and strong interactions, the top quark and flavour, as well as phenomena beyond the Standard Model. We highlight the synergy and complementarity of the different colliders, which will contribute to a uniquely coherent and ambitious research programme, providing an unmatchable combination of precision and sensitivity to new physics.

Çakiroğlu, Ünal; Yildiz, Merve; Mazlum, Ebru; Turan Güntepe, Ebru; Aydin, Şenay
The purpose of this qualitative study was to explore collaborative activities that were carried out via weblogs according to a “learning by design” approach. During the instructional process, Microsoft Publisher was used for a series of infographic design activities. The study participants were 33 undergraduate students who were enrolled in an Arts Education program. The data sources included weblogs that were used by the participants to discuss the design process, as well as reflection reports that they provided. The data were analyzed according to Murphy’s collaboration model, which involved associating the participants’ experiences in the design process with the sub-phases of collaboration outlined in the model. The results indicated that, through the use of weblogs, the participants were able to design infographics via a “learning by design” approach. The weblogs allowed students to share their knowledge, and thereby to develop better artifacts. It is hoped that the study may provide insights concerning the link between weblogs and the learning by design approach in graphic design activities.

Çelebi, S.; Ozturk, A.; Uysal, E.; Kutuk, S.; Duzgun, I.
The evolution of the rate of flux creep along the major hysteresis envelopes in a Y0.5Lu0.5Ba2Ca3Oy sample synthesized by a modified melt powder melt growth (MPMG) method at 25 K has been investigated. Magnetic relaxation rates depend strongly on the prior magnetic history. Calculations based on the critical state model can reproduce quite well the experimental data for magnetization when we have chosen the field exponent n = 0.3 in critical current density, Jc(Ha) = Jc0/(Ha−IM)n, where IM = Ha when 0 < H < Hc1 and (Formula presented.) when Ha ≥ Hc1. Using the field-cooled magnetization MFC data as well as the comparison of experimental and calculated M–H hysteresis loop, we estimated Hc1 = 500 Oe, p = 0, and the penetration field H∗ = 20 kOe. The apparent pinning energy was estimated as 62 meV for the remanent magnetization upon an excursion of 40 kOe.

Başoğlu, M.; Yanmaz, E.
Sintered Nd-Fe-B magnets are some of the strongest magnetic materials showing magnetic properties. Blending addition is frequently performed in order to improve the magnetic properties of these materials. In this work, high-melting point Ni and low-melting point Cu were added to Nd15Fe77B8 ingot by blending. As a result of structural analysis, it was observed that 0.2 wt% Cu + Ni addition improved the structure of the material; on the other hand, excessive addition resulted in porosity. It was also observed that 0.2 wt% addition improved the magnetic properties, and Curie temperature increased with increasing addition ratio.

Baltacı, Cemalettin; İlyasoğlu, Huri; Yüksel, Ferhat
This study presents a method validation procedure for the determination of aflatoxin B1, B2, G1, and G2 in hazelnut, hazelnut paste, walnut, peanut, pistachio, corn, and wheat. The method consisting of clean-up with immunoaffinity column, high performance liquid chromatography with postcolumn derivatization and fluorescence detection was validated in accordance with Commission Regulation 2004/882/EC. The selectivity, linearity, decision limit, detection capability, detection and quantification limits, precision, recovery, ruggedness, and measurement uncertainty of the method were determined. The limit of detection and limit of quantification values (μg/kg) were: aflatoxin B1, 0. 02, 0. 07; aflatoxin B2, 0. 01, 0. 02; aflatoxin G1, 0. 02, 0. 07; and aflatoxin G2, 0. 01, 0. 03. The relative standard deviation values for the repeatability and within-laboratory reproducibility were below 4 and 5 %, respectively. The recovery values of the spiked samples ranged from 80 to 105 %. These results complied with minimum performance criteria established by regulation 2006/401/EC. Therefore, the procedure can be implemented for the routine analysis of aflatoxins in the studied matrices.
