A Securitization Approach to Qatar’s Foreign Policy Making
The securitisation of military and political sectors has been underway for decades in the context of Qatari politics. Conceptualising the role of security in Qatar’s foreign policymaking is the primary purpose of this study. Qatar’s security tools and strategies in the initial era of the Gulf Crisis 2017 are central elements of this research using the Copenhagen school's securitisation framework. The Gulf Crisis started in June 2017 and took more than 3 years for the parties to warm the relations again. This research depicts the early process of the Gulf Crisis 2017 through categorising threats and vulnerabilities posed to Qatar's military and political security
Maskin-Monotonic Scoring Rules
Cataloged from PDF version of article.We characterize which scoring rules are Maskin-monotonic for each social choice problem as a function of the number of agents and the number of alternatives. We show that a scoring rule is Maskin-monotonic if and only if it satisfies a certain unanimity condition. Since scoring rules are neutral, Maskin-monotonicity turns out to be equivalent to Nash-implementability within the class of scoring rules. We propose a class of mechanisms such that each Nash-implementable scoring rule can be implemented via a mechanism in that class. Moreover, we investigate the class of generalized scoring rules and show that with a restriction on score vectors, our results for the standard case are still valid
Distribution of some elements in Veronica scutellata L. from Bolu,Turkey: soil-plant interactions
Veronica scutellata L. occurs in moist and wet habitats, such as ponds, marshes and other wetlands. This study was conducted on this species to examine its mineral element uptake status in terms of interactions between soil and plant. Experimental materials were taken from the Southern coast of Black Sea at coordinates 40º36’N and 31º16’E at an altitude of 1400 m above sea level from Bolu – Turkey; using standard methods and plant (root, stem and leaf parts) and soil mineral element measurements (Al, B, Ca, Cu, Fe, K, Mg, Mn, Na, Ni and Zn) were done. During the study, ICP-OES was employed for the measurement of mineral elements. It was observed that considerable amounts of B, Ca, K, Mg, Mn, Na and Zn are accumulated by the plant
Macro- and micro-strain in GaN nanowires on Si(111)
We analyze the strain state of GaN nanowire ensembles by x-ray diffraction.
The nanowires are grown by molecular beam epitaxy on a Si(111) substrate in a
self-organized manner. On a macroscopic scale, the nanowires are found to be
free of strain. However, coalescence of the nanowires results in micro-strain
with a magnitude from +-0.015% to +-0.03%.This micro-strain contributes to the
linewidth observed in low-temperature photoluminescence spectra
HERITABILITY AND PATH ANALYSIS OF SOME ECONOMICAL CHARACTERISTICS IN LENTIL
Twenty-nine lentil (Lens culinaris Medik) genotypes were grown from 1997/98 to 1998/2001 at Dicle University, Faculty of Agriculture in Diyarbakir The heritability for days to fl owering and maturity, plant height, height of lowest pod, number of pod per plant, 1000 seed weight and seed yield were estimated as 0.94, 0.78, 0.52, 0.72, 0.37, 0.87 and 0.53, respectively. The path analysis indicated that total biological yield and number of clusters and pods per plant
had very high positive direct effect on seed yield
Preparation and characterization of photochromic effect for ceramic tiles
Ceramic tile industry is developing due to the technological researches in scientific area and new tiles which are not only a
traditional ceramic also have many multiple functionalities have been marketed nowadays. These tiles like photocatalytic,
photovoltaic, antibacterial and etc. improve the quality of life and provide lots of benefits such as self cleaning, energy
production, climate control. The goal of this study was to enhance the photochromic function on ceramic tiles which is the
attitude of changing color in a reversible way by electromagnetic radiation and widely used in many areas because of its
aesthetic and also functional properties. High response time of photochromic features of ceramic tiles have been achieved by
employing of polymeric gel with additives of photoactive dye onto the ceramic surface. Photochromic layer with a thickness
of approximately 45- 50 μm was performed by using spray coating technique which provided homogeneous deposition
on surface. Photochromic ceramic tiles with high photochromic activity such as reversibly color change between ΔE= 0.29
and 26.31 were obtained successfully. The photochromic performance properties and coloring-bleaching mechanisms were
analyzed by spectrophotometer. The microstructures of coatings were investigated both by stereo microscopy and scanning
electron microscopy (SEM).Peer reviewe
A phylogenetic analysis of Jurinea (Compositae) species from Turkey based on ITS sequence data
In this study, the taxa which belong to the Jurinea Cass. genus, grown naturally in Turkey and collected from different localities, are compared in terms of their internal transcribed spacer (ITS) regions of nuclear ribosomal DNA (nrDNA). The DNAs of the taxa were isolated by using a commercial kit (Nucleon Phytopure). Sequences were aligned with Clustal X. Phylogenetic relationships are assessed by sequence analysis, conducted with the DNASTAR software after the amplification of ITS regions with the universally recognized primers, named as 17SE and 26SE. In conclusion, morphologically similartaxa are also clustered together when a phylogenetic analysis is conducted based on molecular data. Jurinea species of the Anatolian peninsula are closely related with the topography of the region and certain level of molecular isolation of the species is evidenced
Karyotype analyses of the species of the genus Jurinea Cass. (Compositae) in Turkey
In this study, karyotype analyses of 13 species belonging to the genus Jurinea Cass. (Compositae) and grown naturally in Turkey were conducted. These taxa include Jurinea alpigena C. Koch, Jurinea ancyrensis Bornm., Jurinea aucherana DC., Jurinea cadmea Boiss., Jurinea cataonica Boiss. and Hausskn., Jurinea consanguinea DC., Jurinea cypria Boiss., Jurinea macrocalathia C. Koch., Jurinea macrocephala DC., Jurinea mollis (L.) Reichb., Jurinea pontica Hausskn. and Freyn ex Hausskn., Jurinea pulchella DC., Jurinea ramulosa Boiss. and Hausskn. Karyotype analysis of all the species are introduced to the scientific community for the first time and they were obtained through an Image analysis system. The study has made contribution to the cytotaxonomic revision of the genus Jurinea in Turkey.Key words: Asteraceae, Image analysis, Jurinea, karyotype, Turkey
