This study aims to provide information about the Q Concept defined as the division of journal impact factors into quartiles based on given field categories so that the disadvantages resulting from the direct use of journal impact factors can be eliminated. While the number of Original articles published in the Web of Science (WoS) database-indexed journals like SCI, SSCI and A&HCI is an important indicator for research assessment in Turkey, neither the journal impact factors nor the Q Concept of these papers have been taken into account. Present study analyzes the scientific production of the Amasya University researchers in journals indexed in WoS database in the period 2014-2018 using the Q concept. The share of publications by Q category journals as well as the average citations received by the works from Amasya University were compared to the average situation in Turkey and other different countries in the world. Results indicate that the articles published by Amasya University researchers were mostly published in low impact factor journals (Q4 journals) (36.49%), in fact, only a small share of papers were published in high impact journals (14.32% in Q1 journals). The share of papers published in low impact journals by researchers from Amasya University is higher than the Turkish average and much higher than the scientific leading countries. The average citations received by papers published in Q1 journals was around six times higher than papers published in Q4 journals (8.92 vs. 1.56), thus papers published in Q1 journals received 30.02% citations despite only 14.32% of the papers was published in these journals. The share of papers published which were never cited in WoS was 27.48%, increasing from 9.68% in Q1 to almost half (48.10%) in Q4. The study concludes with some suggestions on how and where the Q Concept can be used.
The recurrence relations are presented for the calculation of basic overlap integrals, by making use of which other overlap integrals are calculated analytically. These recurrence relations are especially useful for the calculation of any overlap integral for large quantum numbers. For the arbitrary values of screening constants of atomic orbitals and internuclear distances an accuracy of the computer results is satisfactory for the values of principal quantum numbers of Slater functions up to 50.
In academic performance assessments, citations and citation-based metrics play a pivotal role. Among the elements that influence the success of an article, the title stands out as the first point of contact for editors, reviewers, and readers. Consequently, the title length-citation relationship is an extensively studied issue. While the dominant language used in the databases is English, rhetorical discourses are dominant in the non-English literature about the appropriate length of titles. This study investigates the relationships between title lengths, article downloads, and citations for educational research articles in the Turkish context. Specifically, it focuses on articles indexed in TRIndex and Google Scholar that were published in the Turkish Journal of National Education between 2010 and 2015. The parametric and nonparametric tests using different approaches (median and quarterly classification, correlation analysis) reveal a low negative correlation between title lengths and citations and downloads, a moderate positive correlation between downloads and citations, and a high positive correlation between the citations in the databases. It has been observed that the articles with short titles are read and cited more than the ones with longer titles. These findings align with previous research conducted in the English language. The results suggest that the optimal title length for educational research coincides with “ the magical number seven, plus or minus two,” often referred to as Miller’s Law, which represents the number of objects an individual can retain in their short-term memory. The study provides practical implications for authors, editors, and researchers on optimizing title length for better visibility and impact.
The evolution of Turkish Journal of Chemistry (Turk J. Chem) Hirsch index (h-index) over the period 1995-2005 is studied and determined in the case of the self and without self-citations. It is seen that the effect of Hirsch index of Turk J. Chem has a highly positive trend during the last five years. It proves that Turk J. Chem is improving itself both in quantity and quality since h-index reflects peer review, and peer review reflects research quality of a journal.

Abstract The modified overlap and nuclear‐attraction integrals over Slater‐type orbitals are calculated for extremely large quantum numbers using Gegenbauer coefficients and basic overlap integrals. The accuracy of the results is quite high for the principal quantum numbers of Slater functions and for arbitrary values of internuclear distances and screening constants of atomic orbitals. © 2002 John Wiley & Sons, Inc.

As an example of the use of the analytical formulas derived for electric multipole moment integrals over STOs in our previous work (I.I. Guseinov, et al., J. Mol. Struct. (Theochem) 465 (1999) 5), the -pole electric moments have been calculated for the ground electronic states of LiH, BH and FH of the first-row diatomic hydride molecules. Calculated electric multipole moment values are in agreement with literatures. By the use of these analytical formulas the -pole moments for multiatomic molecules can be evaluated most efficiently and accurately by employing STOs as basis sets.
Abstract A general formula has been established for the expansion of the product of two normalized associated Legendre functions centered on the nuclei a and b . This formula has been utilized for the evaluation of two‐center overlap and nuclear attraction integrals over Slater‐type orbitals (STOs) with integer and noninteger principal quantum numbers. The formulas given in this study for the evaluation of two‐center overlap and nuclear attraction integrals show good rate of convergence and great numerical stability under wide range of quantum numbers, orbital exponents, and internuclear distances. © 2001 Wiley Periodicals, Inc.
