Publication Tarihin Ulus Devlet İçin Gerekliliği: Karabağ Örneği(TESAM Akademi, 2026-02-18)Milliyetçilik kuramlarından biri olan modernist yaklaşıma göre modern devletler 18.yy’de moderniteyle birlikte ortaya çıkmıştır. Bu kıstasta, millet, milliyetçilik, egemenlik, toprak kavramları, modern anlamda ulus-devletlerin ayrılamaz bileşenleridir. Bu çalışmada ulus-devletin inşasında tarihin rolüne vurgu yapılmakta ve genel anlamda Azerbaycan’ın, özelinde ise Karabağ’ın tarihi ele alınmaktadır. Ruslar, kendi çıkarları doğrultusunda Ermenileri kullanmış ve uygulamış oldukları iskân politikası sonucu bölgede demografik değişimin onların lehine evrilmesine sebep olmuşlardır. Ermenilerin, Azerbaycan toprakları üzerindeki talepleri hususundaki baskıları bu olgu üzerinden şekillenmiştir. Tarihi gerçeklerin yardımıyla birlikte, Azerbaycan’ın yoğun mücadelesi zaferle sonuçlanmıştır. Bu çalışma, Karabağ savaşında Azerbaycan milliyetçiliğinin neden Ermenistan milliyetçiliği karşısında başarılı olduğunu sorgulamaktadır. Sonuç olarak yapay tarihin, gerçekte var olanı yenmesinin mümkün olmayacağı vurgulanmaktadır. Çalışmada konuyla ilgili literatür taraması yöntemi kullanılmış, akademik kitaplar, hakemli dergiler ve medya arşivlerinden yararlanılmıştır. - Some of the metrics are blocked by yourconsent settings
Publication Mathematical modeling and optical-thermal analysis of a novel solar beam down parabolic dish concentrator(Elsevier BV, 2025-09)This paper presents a comprehensive examination of the mathematical modeling and optical-thermal analysis of an innovative solar beam-down parabolic dish concentrating (BD-PDC) collector. This study aims to develop a novel design that addresses key challenges such as heat transfer losses and extensive structural requirements inherent in traditional concentrated solar power systems. The innovative BD-PDC system integrates a secondary hyperbolic reflector with a primary parabolic dish collector, directing concentrated solar radiation towards a receiver at ground level. A comprehensive mathematical model was developed and analyzed to assess the optical and thermal performance of the proposed system. The research utilizes the Monte Carlo ray-tracing methodology for optical analysis to optimize various system components and create a prototype. Furthermore, to evaluate the performance of the BD-PDC system under real-world conditions, this study incorporates direct normal irradiance (DNI) data from Jodhpur, India. The diurnal simulations indicate that the BD-PDC exhibits considerable effectiveness in harnessing and focusing solar radiation, yielding peak thermal efficiencies of 76.8 % while generating solar thermal power of 16.51 kWh per day. An assessment of system efficacy was conducted across various seasonal intervals, with peak performance noted during the winter season. This investigation provides critical insights into the design and development of BD-PDC-type solar concentrator systems, contributing to the advancement of more efficient and sustainable solar energy technologies. - Some of the metrics are blocked by yourconsent settings

Publication Some properties of the pT regions observed at the LHC energies(2025-04-29)The inclusive spectrum of the charged particles, [Formula: see text]0- and [Formula: see text]-mesons produced in the pp collisions at LHC energies were analyzed by fitting them with exponential functions. It was found the spectra were composed of several p[Formula: see text] regions, which could be characterized by the length of the regions [Formula: see text] and two free fitting parameters [Formula: see text] and [Formula: see text]. The study of the [Formula: see text] dependences of the parameters [Formula: see text] and [Formula: see text] and of the energy dependencies of the [Formula: see text], [Formula: see text] and [Formula: see text] showed that the regions can be classified into two groups depending on the values of the [Formula: see text], [Formula: see text] and [Formula: see text]. The values of the [Formula: see text] and [Formula: see text] for the first group don’t depend on colliding energy and the type of the particles (though the values of [Formula: see text] increase linearly with energy) whereas the characteristics in the second group of regions show strong dependencies. It was found that the ratio of the length for the [Formula: see text]-mesons to one for the [Formula: see text]0-mesons is approximately equal to the ratio of their mass: [Formula: see text]. Assuming that the values of the [Formula: see text] are directly proportional to the string tension the result could be considered as evidence in favor of parton string fragmentation dynamics. The increase in the lengths for the [Formula: see text]-mesons’ regions is accompanied by an increase of the values for the parameter [Formula: see text]. It can mean that the [Formula: see text]-mesons were produced at smaller values of [Formula: see text] compared with that for [Formula: see text]0-mesons. The results show that for the first group of regions the lengths of the regions are [Formula: see text]3–5 times greater than the lengths of neighboring, lower p[Formula: see text] regions. For the second group of regions the lengths of the regions are [Formula: see text]1–2 times greater than the lengths of neighboring lower p[Formula: see text] region. In the framework of the string fragmentation and hadronization dynamics, this could mean that the particles in the group [Formula: see text] of regions are produced through previous-generation strings decays into [Formula: see text]3–5 strings while those in group [Formula: see text] originate from previous-generation strings decays into [Formula: see text]2 strings.
