Differences in metal profiles revealed by native mussels and artificial mussels in Sarcay Stream, Turkey: implications for pollution monitoring
No full text0000-0002-2139-7655WOS: 000442365500005Using the native mussel Unio crassus and artificial mussels (AMs), profiles of 11 metals (Cd, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb, U, Zn) were determined and compared in winter and summer along a pollution gradient in Sarcay Stream, Turkey. Principal components analysis and correlation analysis showed that metal profiles in the native mussels and AMs were different. Concentrations of most metals were significantly higher in the native mussels compared with AMs, suggesting that metals in Sarcay Stream predominantly existed in suspended particulates and food compartments, rather than in dissolved form. Although U was not readily accumulated by the native mussels, it could be taken up by AMs. Overall, the results suggest that the use of native mussels and AMs in water quality monitoring can provide complementary information and a better estimate and coverage of different metal species and forms in aquatic environments.Scientific Research Project Office of Mugla Sitki Kocman University [13/72]; Education University of Hong Kong [R3721]This work was supported by the Scientific Research Project Office of Mugla Sitki Kocman University (Project number: 13/72) awarded to Tuncer Genc, and a start-up grant from the Education University of Hong Kong (R3721) awarded to Rudolf Wu.

THREE-DIMENSIONAL COMPUTATIONS FOR BOUNDARY OPTIMAL CONTROL PROBLEMS IN INCOMPRESSIBLE MAGNETOHYDRODYNAMICS
No full textIn this paper we present the results of some three-dimensional computations of boundary optimal control problems in incompressible Magnetohydrodynamics, obtained with the lifting function approach and with the implementation of a gradient algorithm for the solution of the optimality system. Possible applications of these problems are manifold, such as aluminum casting in metallurgy, crystal growth in semiconductor industry and liquid metal MHD pumps and generators. In these applications it is of great interest to achieve the control on the velocity profile through the Lorentz force acting on the fluid.
The magnetic field on the boundary can be used as a means for steering the velocity profile to a desired one or for minimizing other quantities of interest. With the lifting functio
1-{2-Benzyloxy-2-[4-(morpholin-4-yl)phenyl]ethyl}-1H-benzimidazole
No full textIn the title compound, C26H27N3O2, the morpholine ring adopts a chair conformation. The benzene and phenyl rings are inclined to the benzimidazole mean plane by 7.28 (6) and 61.45 (4)°, respectively. In the crystal, pairs of weak C—H...O hydrogen bonds link the molecules into inversion dimers. These dimers are further connected via weak C—H...N hydrogen bonds. A weak C—H...π interaction is also observed

A Brief Look at Automation Activities in Turkish University Libraries
Full text linkTurkey, one of the cradles of civilisation, is a republic founded by Kemal Ataturk in 1923 after the collapse of the 600-year-old Ottoman Empire. Its location in two continents (Europe and Asia) has been a central factor in its history, culture and politics; Turkey has often been called a bridge between East and West. Turkey, Islamic in tradition, is a newly industrialised democratic nation of 55 million people.
In Turkey, there are 29 universities (28 state and one private). They are governed by a common law, namely the Higher Education Act. The majority of universities have decentralised libraries, which is largely due to the fact
that there has been no legislation or by-laws that specifically govern the establishment and organisation of libraries within a university. The importance of computers for library and information centres has long been recognised in Turkey. The history of computer use goes back to the early 1970s when university libraries started to use computers mainly for 'batch' jobs, such as the production of a union catalogue of serials, acquisition lists and the like. In a recent survey it was shown that almost all university libraries have a strong interest in automation1. Some have been planning to computerise their operations, whilst others are considering this option seriously. The existing computer use in university libraries is heavily centred in the following operations: union lists of serials and books, circulation control, acquisition, cataloguing and current awareness
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Comparison of factors affecting patients with a myofascial temporomandibular disorder with and without sleep bruxism
No full textAims and Background: The aim of the present study was to evaluate the relationship between jaw function, neck disability, sleep quality, fatigue, and headache in patients with myofascial temporomandibular disorder (TMD) with sleep Bruxism (SB) and without it (non-SB). Subjects and Methods: This case-control study was conducted with a total of 200 myofascial TMD patients, comprising 91 identified as SB and 109 as non-SB. The Jaw Function Limitations Scale (JFLS), Neck Disability Index (NDI), Pittsburgh Sleep Quality Index (PSQI), Fatigue Severity Scale (FSS), and Headache Impact Test-6 (HIT-6) scales and indexes were used. Results: In the group with SB compared to the non-SB group, JFLS, NDI, PUKI, and FSS scores were statistically significantly higher (P < 0.001). No statistically significant difference was found between the groups in terms of visual analog scale (VAS) (P = 0.127) and HIT-6 scores (P = 0.365). The probability of having JFLS in patients with SB compared to those without was folded 3.551 times (P = 0.002), and the probability of having NDI increased 3.473 times (P = 0.002). In addition, SB was observed to trigger poor sleep quality (P < 0.001). There was no statistically significant determinant of bruxism on FSS (P = 0.196), and on HIT-6 (P = 0.488). Conclusion: It can be concluded that SB causes limitation of the jaw's functional activities, neck problems, and decreased sleep quality in myofascial TMD. These findings emphasize the importance of considering SB when evaluating and treating patients with myofascial TMD problems. © 2022 Nigerian Journal of Clinical Practice | Published by Wolters Kluwer .
