Anthroponyms: The lexico-semantic approach to word formation and its social and cultural implications
No full textThe relevance of the study is that specific individual linguistic customs and traditions are characteristic of each nation. The objective of the study is to examine the key aspects of anthroponyms and the methodology of their development in Turkish and Kazakh languages. In conducting the research, general scientific and special methods were used to achieve its goals and objectives. Its main results can be defined as follows. It was argued that the lexical-semantic approach to word formation is one of the most widespread approaches to the creation of meaningful anthroponyms, reflecting the features and characteristics of the named person. According to the results of the conducted research, the necessity of studying anthroponyms and word formations was revealed and substantiated. The reason for this is that they have an important social and cultural significance in the process of interaction between the peoples of the world, as well as the study of their cultural heritage. The latter is directly related to the fact that personal names express moral and philosophical values of a certain ethos, fix in themselves the history, traditions, and beliefs of a particular society or community. As a result of the research, it was concluded that anthroponyms in the onomastic field of any language of the world are nuclear constituents. At the same time, the whole set of anthroponyms contained in it will be unique, as the factors influencing the speakers of the language will differ. © 2025 Elsevier B.V., All rights reserved
Non-Invasive Point-of-Care Detection of Methamphetamine and Cocaine via Aptamer-Based Lateral Flow Test
No full textDrug abuse is a major public problem in the workplace, traffic, and forensic issues, which requires a standardized test device to monitor on-site drug use. For field testing, the most important requirements are portability, sensitivity, non-invasiveness, and quick results. Motivated by this problem, a point of care (POC) test based on lateral flow assay (LFA) was developed for the detection of cocaine (COC) and methamphetamine (MET) in saliva which has been selected as the matrix for this study due to its rapid and non-invasive collection process. In the design strategy of an LFA test, the use of gold nanoparticles (AuNPs) with strong optical properties has been combined with the advantages of selecting aptamers under in vitro conditions, making it a highly specific and stable recognition probe for the detection of small molecules in saliva. The developed aptamer-based LFA in a competitive format, was able to detect COC and MET in synthetic saliva at concentrations as low as 5.0 ng/mL. After analytical performance studies, the test system also detected COC and MET in real patient samples, which was verified by chromatographic methods.TUBITAK 1005 National New Ideas and New Products Research Funding Program; [221Z083]This research was funded by TUBITAK 1005 National New Ideas and New Products Research Funding Program with the project no: 221Z083

Uso da competência das parteiras relacionada à tecnologia de parto no manejo do trabalho de parto: um estudo observacional
No full textObjective: The present study was aimed at investigating how midwives used their birth technology-related competence in labor management. Method: The study sample consisted of 14 midwives. Data were collected through interviews and by observing how the midwives followed up pregnant women. During the observations, the “Midwife Information Form”, “Form to Assess Competence Areas of Midwives in Birth Technology” and “Form to Assess Technology Used in Labor” were used. Each midwife was observed five times. Results: The assessment of the birth technology competence areas of the midwives revealed that they had deficiencies in the “caring”, “communication” sub-domains of the interpersonal skills domain and “decision making”, “traditional midwifery skills” sub-domains of the clinical competence domain. Conclusion: According to the analysis of the assessment of the technology used, the midwives working in delivery rooms tended to use low-tech devices. Traditional midwifery skills used by the participating midwives during labor were inadequate. © 2025 Elsevier B.V., All rights reserved
Investigation of the effects of various parameters on wireless power transfer efficiency
No full textElectric vehicles have dominated the automotive market, especially in recent years. However, the charging problem that stresses drivers continues. Although conductive charging is an established technology, it still needs to meet user expectations fully. On the other hand, wireless charging technology attracts users' attention with dynamic charging features. Although this technology improves daily, efficiency is not at the desired level. In this study, a wireless power transfer system was designed for electric vehicles, and the factors affecting the charging efficiency were investigated. This system consists of an inverter, a compensation system, and a load. The efficiency of the system according to cable type, air gap, cooling, and pulse-width modulation parameters was observed through 40 experiments, each lasting 20 min. In addition to efficiency, the frequency behavior was also investigated. Experimental results were compared with models designed in MATLAB and ANSYS software. The average errors between the experimental and simulation results are 1.75, 2.03, 1.85, 1.58, and 2.00% for air gaps of 19-20, 55-56, 91-92, 127-128, and 145-146 mm, respectively. Power was transferred wirelessly with a minimum efficiency of 59.25% at a 145 mm air gap and a maximum efficiency of 85.74% at a 56 mm air gap in 300 W tests.Scientific and Technological Research Council of Turkey (TUBITAK) [123E104]This study was supported by Scientific and Technological Research Council of Turkey (TUBITAK) under the Grant Number 123E104.

Footwear breathability test machine: A new method and system design for testing footwear breathability and its thermal comfort, case study on leather boot
No full textThe breathability and thermal comfort of footwear, which are essential in everyday life, have a significant impact on user satisfaction. Despite their importance, there is currently no standardised device or procedure to directly test these aspects. The aim of this study is to develop a system and method for evaluating the breathability and thermal comfort of footwear using a foot model that mimics human perspiration and temperature. The model takes into account the distribution of eccrine glands, sweating rate, sweat release areas and foot temperature. Two test principles were applied: (i)measurement of internal temperature and humidity using sensors to assess comfort and (ii)evaluation of moisture management by monitoring the weight gain of footwear, socks and footbed during an 8-h sitting simulation. The system was tested on three full leather military boots, with data collected by sensors and weight measurements. The results showed that 65% of the sweat released was absorbed by the system, with 36% absorbed by the boot, 12% by the footbed and 52% by the sock. The Foot Comfort Logical Scale (FCLS) indicated no temperature discomfort during the trials, but moisture-related discomfort occured after about 240 min and worsened after 300 min when humidity reached 80%. The study demonstrated the effectiveness of the system in simulating the breathability and thermal comfort of footwear, with the results agreeing well with established standards and the literature. Future research will focus on testing different footwear types, incorporating dynamic motion systems and refining the FCLS to improve the accuracy of comfort assessment. © 2025 Elsevier B.V., All rights reserved
An Experimental Evaluation of Indoor Localization in Autonomous Mobile Robots
No full textHigh-precision indoor localization and tracking are essential requirements for the safe navigation and task execution of autonomous mobile robots. Despite the growing importance of mobile robots in various areas, achieving precise indoor localization remains challenging due to signal interference, multipath propagation, and complex indoor layouts. In this work, we present the first comprehensive study comparing the accuracy of Bluetooth low energy (BLE), WiFi, and ultra wideband (UWB) technologies for the indoor localization of mobile robots under various circumstances. In the performed experiments, the error margin of the WiFi-based systems reached 608.7 cm, which is not tolerable for most applications. As a commonly used technology in the existing tracking systems, the accuracy of BLE-based systems is at least 44.12% better than that of WiFi-based systems. The error margin of the BLE-based system in tracking static and mobile robots was 191.7 cm and 340.1 cm, respectively. The experiments showed that even with a limited number of UWB anchors, the system provides acceptable accuracy for tracking the mobile robots. Using only four UWB beacons in an environment of about 431 m2 area, the maximum error margin of detected positions by the UWB-based tracking system remained below 13.1 cm and 28.9 cm on average for the static and mobile robots, respectively. This error margin is 88.05% lower than that of the BLE-based system and 93.27% lower than that of the WiFi-based system on average. The high tracking precision, the need for a lower number of anchors, and the decreasing hardware costs point out that UWB will be the dominating technology in indoor tracking systems in the near future.Technological Research Council of Turkey (TUBITAK); [123E094]This research was funded by the Technological Research Council of Turkey (TUBITAK) grant number 123E094
Factors Contributing to the Diabetes Burden in the Elderly: A Clinical Perspective
No full textAim: This study aims to evaluate the various factors that contribute to the burden of diabetes in elderly individuals with type 2 diabetes. Methods: The descriptive and cross-sectional study was conducted in the internal medicine clinic of a training and study hospital in T & uuml;rkiye between January 2018 and May 2019. The study sample consisted of 102 elderly individuals aged 65 years and older with type 2 diabetes. Data were collected through face-to-face interviews using the Sociodemographic Characteristics Data Form and the Burden of Diabetes in the Elderly Scale. Results: The mean total score for the Elderly Burden Diabetes Scale of participants' was 50.98 +/- 15.59. When the scores (min = 18, max = 88 points) that could be obtained from the scale were taken into account, it was evident that the diabetes burden of elderly individuals with type 2 diabetes was below the moderate level. Age group, marital status and duration of diabetes diagnosis did not affect diabetes burden (p > 0.05). Diabetes burden was higher in patients with education below the undergraduate level, those who used combined oral antidiabetic and insulin treatment, and those with comorbidities (p < 0.05). While there was a negative relationship between comorbidity status and diabetes burden, there was a positive relationship between diabetes treatment and diabetes burden (p < 0.05). Conclusions: It was found that the diabetes burden of elderly individuals with type 2 diabetes was below the mean, and combined treatments and the presence of comorbidities increased the diabetes burden
