Scientometric Implosion that Leads to Explosion: Case Study of Armenian Journals

Journal of Data and Information Science 2020年第3期5卷 187-196页

Purpose: The purpose of this study is to introduce a new concept and term into the scientometric discourse and research—scientometric implosion—and test the idea on the example of the Armenian journals. The article argues that the existence of a compressed scientific area in the country makes pressure on the journals and after some time this pressure makes one or several journals explode—break the limited national scientific area and move to the international arena. As soon as one of the local journals breaks through this compressed space and appears at an international level, further explosion happens, which makes the other journals follow the same ***/methodology/approach: Our research is based on three international scientific databases—WoS, Scopus, and RISC CC, from where we have retrieved information about the Armenian journals indexed there and citations received by those journals and one national database—the Armenian Science Citation Index. Armenian Journal Impact Factor(ArmJIF) was calculated for the local Armenian journals based on the general impact factor formula. Journals were classified according to Gl?nzel and Schubert(2003). Findings: Our results show that the science policy developed by the scientific authorities of Armenia and the introduction of ArmJIF have made the Armenian journals comply with international standards and resulted in some local journals to break the national scientific territory and be indexed in international scientific databases of RISC, Scopus, and WoS. Apart from complying with technical requirements, the journals start publishing articles also in foreign languages. Although nearly half of the local journals are in the fields of social sciences and humanities, only one journal from that field is indexed in international scientific databases. Research limitation: One of the limitations of the study is that it was performed on the example of only one state and the second one is that more time passage is needed to firmly

Distribution of secretory inhibitor of platelet microbicidal protein among urethral isolates with its correlation with prostatitis

Asian Journal of Andrology 2008年第2期10卷 189-192页

作者： Iuri B. Ivanov viktor A. Gritsenko Michael D. Kuzmin Department of Human Microbiology Institute of Cellular and Intracellular Symbiosis Russian Academy of SciencesOrenburg 460056 Russia

Aim： To report the detection in vitro of secretory inhibitor of platelet microbicidal protein （SIPMP） phenotypes of urethral isolates along with a comparisonwith isolates from patients with or without chronic bacterial prostatitis （CBP）. Methods： Urethral isolates of Staphylococcus spp. （n = 64）, diphtheroids （n = 28）, micrococci （n = 15）, streptococci （n = 21）, Enterobacteriaceae （n = 9） and Enterococcusfaecalis （n = 19） from patients with or without CBP were tested. SIPMP production was tested by inhibition of platelet microbicidal protein （PMP） bioactivity against Bacillus subtilis and was expressed as percentage of inhibition of PMP bactericidal activity. Results： A significantly higher proportion of CBP-strains （57.78% vs. 16.67%） reduced PMP-induced killing of Bacillus subtilis than non- CBP strains did （P 〈 0.01）. SIPMP levels of staphylococci and Enterococcusfaecalis from the CBP group were significantly higher than those of the control group. Conclusion： These results suggest that SIPMP production is associated with the CBP source. Data from the present study might have significant implications for the understanding of the pathogenesis of CBP. （Asian J Androl 2008 Mar; 10： 189-192）.

A catalog of gliadin alleles:Polymorphism of 20th-century common wheat germplasm

引用

The Crop Journal 2018年第6期6卷 628-641页

作者： Eugene Metakovsky viktor Melnik Marta Rodriguez-Quijano Vladimir Upelniek Jose Maria Carrillo Unidad de Genetica Universidad Politecnica de MadridMadridSpain Vavilov Institute of General Genetics Russian Academy of Sciences MoscowRussia

A new, improved version of the catalog of 182 alleles at the six Gli loci of common wheat(*** L.) shown in electrophoregrams of 128 standard genotypes was used for analysis of1060 cultivars and lines bred in the 20 th century. The most frequent alleles in the studied germplasm occurred with frequencies of 18%–40%, with 30 unique alleles, one in each cultivar. Extremely high genetic diversity was found(average H for the six main Gli loci was0.870 ± 0.046), nearly identical in winter(H = 0.831) and spring(H = 0.856) wheats but differing among 28 groups of cultivars released in 22 countries. Each country or region was characterized by its own specific set of the most frequent Gli alleles, and the 28 cultivar groups formed five main relationship clusters if polymorphism at the six Gli loci was considered. However, different levels of similarity between groups of cultivars were found if polymorphism of the A, B, or D genomes of common wheat was tested separately. In general, the 20 th century germplasm of common wheat was differentiated and structured by country or region and cultivar type(spring or winter). Each elemental genome(in particular, A and D) contributed to the structure of the polymorphism studied. We propose that the structure of the wheat germplasm was a result of natural selection under the ecoclimatic conditions of cultivation specific to each country or region. As many as 27.4% of cultivars studied violated the requirement of the DUS rules for uniformity, being represented by mixtures of two or more closely related genotypes. However, the composition of a cultivar as a set of related but different genotypes may contribute to its adaptivity, and thereby to the known high plasticity of common wheat.

The study focuses on the in flue nee of Ni and Bi on alkali me etha nol oxidati on reacti on (EOR) activities, stabilities and structure characteristics of carb on supported Pd-based nano catalysts (Pd/C, Pd6oNi4o/C, Pd6oBi4o/C, Pd6oNi2oBi2o/C) by cyclic voltammetry/chr ono amperometry using rotating disk electrode and various physico-chemical methods such as X-ray powder diffraction, X-ray photoelectron spectroscopy, transmission electron microscopy coupled with energy dispersive X-ray spectroscopy and inductively coupled plasma optical emission spectrometry. Nickel generates more adsorbed OH on the Pd catalyst surface than Bi and promotes the oxidation of adsorbed ethanol species. This results in a low onset potential toward ethanol oxidation with high current density. The presenee of Bi facilitates high toleranee toward various reaction in termediates resulting from the incomplete etha nol oxidation, but might also initiate the agglomerati on of Pd nano particles. The no vel Pd60Ni20Bi20/C nanocatalyst displays exceptional byproduct toleranee, but only satisfying catalytic activity toward ethanol oxidation in an alkaline medium. Therefore, the EOR performanee of the novel carbon supported ternary PdxNiyBiz anode catalyst with various atomic variations (Pd70Ni25Bi5/C, Pd70Ni20Bi10/C, Pd80Ni10Bi10/C and Pd40Ni20Bi40/C) using the common instant reduction synthesis method was further optimized for the alkaline direct ethanol fuel cell. The carbon supported Pd:Ni:Bi nano catalyst with atomic ratio of 70:20:10 displays outsta nding catalytic activity for the alkaline EOR compared to the other PdxNiyBiy/C nanocatalysts as well as to the benchmarks Pd/C, Pd60Ni40/C and Pd60Bi40/C. The synergy and the optimal content in consideration of the oxide species of Pd, Ni and Bi are crucial for the EOR kinetic enhancement in alkaline medium.
