Article The Role and Importance of Human Capital in Exports and Growth: The Case of Türkiye(Inderscience Publishers, 2026) Temiz, Dilek; Gökmen, AytaçArticle Population Dynamic Caused by War Involvement via Fractional Derivative on Time Scales(Inderscience Publishers, 2019) Baleanu, Dumitru; Agheli, Bahram; Neamaty, Abdolali; Nategh, MehdiArticle The Impact of Technology on Economic Growth in Turkey(Inderscience Publishers, 2025) Ercan, M.; Temiz, D.; Gökmen, A.The Turkish economy has been suffering from trade imbalance for a long time. Exporting high value-added products will diminish Turkey’s dependence on foreign resources for capital and imported products. At the same time, it may be possible to divert more resources from gross domestic product (GDP) to R&D funds. Appropriate and efficient usage of technology will help companies innovate and find new areas of employment. As a result, the Turkish economy may have a better chance of obtaining a sustainable economic growth for the longer term. This study concludes that increased R&D expenditures leads to a rise in technology and this in turn contributes positively to economic growth. The results obtained from the study show that technology affects Turkey’s economic growth. Therefore, Turkey needs to work harder in the field of technology in order to achieve sustainable growth. Improving the situation and quality of research and development activities in Turkey, encouraging research and development investments by both the government and the business sector should be priority reform movements for Turkey. Policy makers should support science and technology, make institutional arrangements for intellectual property rights and raise the level of education, and make arrangements to increase R&D spending. © 2025 Elsevier B.V., All rights reserved.Article Citation - Scopus: 8A Partial Coverage Hierarchical Location Allocation Model for Health Services(Inderscience Publishers, 2023) Karasakal, O.; Karasakal, E.; Töreyen, Ö.We consider a hierarchical maximal covering location problem (HMCLP) to locate health centres and hospitals so that the maximum demand is covered by two levels of services in a successively inclusive hierarchy. We extend the HMCLP by introducing the partial coverage and a new definition of the referral. The proposed model may enable an informed decision on the healthcare system when dynamic adaptation is required, such as a COVID-19 pandemic. We define the referral as coverage of health centres by hospitals. A hospital may also cover demand through referral. The proposed model is solved optimally for small problems. For large problems, we propose a customised genetic algorithm. Computational study shows that the GA performs well, and the partial coverage substantially affects the optimal solutions. © 2023 Inderscience Enterprises Ltd.Article Silicon-Based Core-Shell Nanoparticle's Nanobiomedical Characterisation(Inderscience Publishers, 2019) Sana, F.A.; Farhadnia, F.; Salmanogli, A.Using functionalised nanoparticles in nanobiomedical applications cause to raise questions about unintentional effect of such powerful agents on the human body. In other words, the study of nanoparticle toxicity can be considered as a curtail key for the biological applications. In this study, the core/shell nanoparticles such as Si/Au and SiO2/Au were synthesised and functionalised with some biological elements. For satisfying some medical standards and biomedical critical test conditions, a few in-vitro assays as cytotoxicity and haemolysis should be done. For this reason, cytotoxicity and haemolytic effects of the functionalised nanoparticles such as Si/Au/biotin and SiO2/Au/biotin and their derivatives were evaluated on Hep-G2 cells and humane red blood samples. It is shown that cytotoxicity and haemolysis effects of the all synthesised nanoparticles are concentration-dependent. Also, the results are shown that most cytotoxicity and haemolytic effects are observed for Si/Au and SiO2/Au without biotin groups after 48 hours and 30 minutes, respectively. © 2019 Inderscience Enterprises Ltd.Article Citation - Scopus: 5Micro-Wedm of Ni55.8ti Shape Memory Superalloy: Experimental Investigation and Optimisation(Inderscience Publishers, 2021) Akar, S.; Seyedzavvar, M.; Kiliç, S.E.; Meshri, H.A.M.Nickel-titanium superalloy has gained significant acceptance for engineering applications as orthotropic implants, orthodontic devices, automatic actuators, etc. Considering the unique properties of these alloys, such as high hardness, toughness, strain hardening, and development of straininduced martensite, micro-wire electro-discharge machining (μ-WEDM) process has been accepted as one of the main options for cutting intricate shapes of these alloys in micro-scale. This paper presents the results of a comprehensive study to address the material removal rate (MRR) and surface integrity of Ni55.8Ti shape memory superalloy (SMA) in the μ-WEDM process. The effects of discharge current, pulse on-time, pulse off-time, and servo voltage on the performance of this process, including MRR, white layer thickness, surface roughness, and micro-hardness of the machined surface, were investigated by multi-regression analysis using response surface methodology (RSM). The optimisation of input parameters based on the gradient and the swarm optimisation algorithms were also conducted to maximise the MRR and minimise the white layer thickness, surface roughness, and micro-hardness of the machined samples. © 2021 Inderscience Enterprises Ltd..

The eco-efficient management of the vegetable oil production processes has been performed on the units of physical processes, extraction and purification. The results obtained indicated that the loss in raw material can be reduced simply by increasing me height of the sieves used to separate foreign materials (leaves, sand, stones, etc.) from sunflower seeds. Results also indicated that production costs and negative environmental impacts can be decreased by minimising the loss of hexane during the extraction process, and the product quality can be improved and product loss can be prevented by adjusting the amounts of bleaching clay and TriSyl® in me bleaching process. Although the reduction in environmental impacts of the factory could not be valuated, the study showed that the factory can be managed more eco-efficiently without undergoing major process changes with an immediate benefit of approximately 12,000 USD. Copyright © 2007 Inderscience Enterprises Ltd.Article Citation - Scopus: 6Economic Growth - Inflation Nexus and Its Impact on the Development of the Automotive Industry: the Case of Turkey(Inderscience Publishers, 2019) Gökmen, A.; Üstündağ, K.; Dinç, D.T.Economic growth is essential for development and welfare of the citizens of a country. Economic development is an intact process involving potentially entire industries in a state. Also, economic growth is associated with macroeconomic indicators such as GDP, exports, imports, budget surplus or deficits, current account balance, interest and inflation rates. Nonetheless, inflation is an important macroeconomic indicator which can influence industrial development positively or negatively. Moreover, the aim of this study is to analyse the impact of inflation on the total automotive industry production in the Republic of Turkey resting on various econometric applications as JJ cointegration test, VECM, Wald test, Gtranger test and LSM. Copyright © 2019 Inderscience Enterprises Ltd.Article The Relationship Between Turkey's Olive Oil Export Income and Economic Growth(Inderscience Publishers, 2020) Gokmen, A.; Altuntas, S.C.; Dinç, D.T.The purpose of this study is to provide information about the agricultural product sector and the olive and olive oil products. Also, the main purpose of this study is the demonstration of relationship between Turkey's olive oil export income and economic growth figures. This relationship is examined by using the quarterly data in between 1999:Q1 and 2017:Q1. In addition, another aim is to find solutions on the existing problems and to provide recommendations about the sector. © 2020 Inderscience Enterprises Ltd.
