A novel dry granule preparation technology and comparison of granule properties with conventional wet system for ceramic tiles production

Hasan Ergin, Mehmet Uğur Taşkıran, Ahmet Atınç Pilevne, Hatice Turgut, more

Physicochemical Problems of Mineral Processing > 2023 > Vol. 59, iss. 5 > art. no. 167498

The ceramic tile manufacturing process uses a lot of energy, mainly thermal energy, and to a lesser extent electric energy. Total energy costs account for between 50% and 55% of average direct manufacturing costs. Fossil fuel combustion, such as natural gas combustion, produces carbon dioxide emissions. Therefore, energy consumption and emissions issues are vitally important for both environmental...

Celal Öztürk, Murat Taşyürek, Mehmet Uğur Türkdamar

Concurrency and Computation: Practice and Experience > 35 > 4 > n/a - n/a

Object detection is a type of application that includes computer vision and image processing technologies, which deal with detecting, tracking, and classifying desired objects in images. Computer vision is a field of artificial intelligence that enables computers and systems to derive information from digital images and take action or suggestions based on that information. CNN is one of the current...

Does intellectual property protection deliver economic benefits? A multi‐outcome meta‐regression analysis of the evidence

Sefa Awaworyi Churchill, Hoang M. Luong, Mehmet Ugur

Journal of Economic Surveys > 36 > 5 > 1477 - 1509

Both theoretical and empirical work reports contingent and conflicting findings on how intellectual property (IP) protection affects related outcomes such as innovation, technology diffusion, productivity, or growth. To establish where the balance of the evidence lies, we conduct a multi‐outcome meta‐regression analysis to synthesize findings form 91 primary studies that report 1626 effect‐size estimates...

International Journal of Clinical Practice > 75 > 11 > n/a - n/a

Background and Aims Ankaferd Blood Stopper (ABS) was used for in vitro studies of osteosarcoma and colon carcinoma cancer cell lines to reveal the apoptotic and antineoplastic effects. The aim of this study is to evaluate the antineoplastic effect of ABS on bladder cancer cell cultures. Methods We prospectively collected minimum 0.5 cm parts of fresh frozen tumour samples from patients with bladder...

TECHNOLOGICAL INNOVATION AND EMPLOYMENT IN DERIVED LABOUR DEMAND MODELS: A HIERARCHICAL META‐REGRESSION ANALYSIS

Mehmet Ugur, Sefa Awaworyi Churchill, Edna Solomon

Journal of Economic Surveys > 32 > 1 > 50 - 82

The effect of technological innovation on employment is of major concern for workers and their unions, policy makers and academic researchers. We meta‐analyse 570 estimates from 35 primary studies that estimate a derived labour demand model. We contribute to existing attempts at evidence synthesis by addressing the risks of selection bias and that of data dependence in observational studies. Our findings...

Technology Adoption and Employment in Less Developed Countries: A Mixed-Method Systematic Review

Mehmet Ugur, Arup Mitra

World Development > 2017 > 96 > C > 1-18

The implications of technology adoption for productivity, income, and welfare have been studied widely in the context of less developed countries (LDCs). In contrast, the relationship between technology adoption and employment has attracted less interest. This systematic review evaluates the diverse yet sizeable evidence base that has remained below the radars of both reviewers and policy makers....

2017 IEEE International Conference on Robotics and Automation (ICRA) > 64 - 70

2017 IEEE International Conference on Robotics and Automation (ICRA)

Fluidic actuators allow versatile, agile, and powerful motions and are commonly applied in robotics and automation. Likewise, many biological systems use fluidic actuators implemented with tissue for a wealth of tasks and performances. Spiders for example apply a hybrid mechanism of hydraulically actuated joint extension and muscle-based joint flexion to produce movement in two of their seven leg...

Does Government Size Affect Per‐Capita Income Growth? A Hierarchical Meta‐Regression Analysis

Sefa Awaworyi Churchill, Mehmet Ugur, Siew Ling Yew

Economic Record > 93 > 300 > 142 - 171

Since the late 1970s, the received wisdom has been that government size (measured as the ratio of total government expenditure to gross domestic product (GDP) or government consumption to GDP) is detrimental to economic growth. We conduct a hierarchical meta‐regression analysis of 799 effect‐size estimates reported in 87 primary studies to verify if this assertion is supported by existing evidence...

R&D and productivity in OECD firms and industries: A hierarchical meta-regression analysis

Mehmet Ugur, Eshref Trushin, Edna Solomon, Francesco Guidi

Research Policy > 2016 > 45 > 10 > 2069-2086

The relationship between R&D investment and firm/industry productivity has been investigated widely following seminal contributions by Zvi Griliches and others from late 1970s onwards. We aim to provide a systematic synthesis of the evidence, using 1253 estimates from 65 primary studies that adopt the so-called primal approach. In line with prior reviews, we report that the average elasticity...

Inverted-U relationship between R&D intensity and survival: Evidence on scale and complementarity effects in UK data

Mehmet Ugur, Eshref Trushin, Edna Solomon

Research Policy > 2016 > 45 > 7 > 1474-1492

Existing evidence on the relationship between R&D intensity and firm survival is varied and often conflicting. We argue that this may be due to overlooking R&D scale effects and complementarity between R&D intensity and market concentration. Drawing on Schumpeterian models of competition and innovation, we address these issues by developing a formal model of firm survival and using a panel...

Data in Brief > 2016 > 8 > C > 153-157

This data article is related to the research article entitled “Inverted-U relationship between R&D intensity and survival: Evidence on scale and complementarity effects in UK data” (Ugur et al., In press) [1]. It describes the trends in R&D expenditures, employment of R&D personnel and firm entry and exit rates in the UK from 1998 to 2012. We also provide statistics on net employment creation...

2016 IEEE 40th Annual Computer Software and Applications Conference (COMPSAC) > 2 > 65 - 70

2016 IEEE 40th Annual Computer Software and Applications Conference (COMPSAC)

This article discusses a new approach to Fetal Heart Rate Monitoring System (FHRMS) via a mobile integrated Doppler device (mDoppler) for monitoring Fetal Heart Rate (FHR) remotely (i.e. home). The aim of the system is to provide ease of FHR monitoring and computing current fetus risk conditions especially for high-risk pregnancy cases via a mobile integrated Doppler device. FHRMS has its own inferring...

Dynamic co-movements and diversification benefits: The case of the Greater China region, the UK and the US equity markets

Francesco Guidi, Christos S. Savva, Mehmet Ugur

Journal of Multinational Financial Management > 2016 > 35 > C > 59-78

This paper investigates the level of long-run co-movements and short-run dynamics among the Greater China region (Hong Kong SAR, Mainland China and Taiwan), the UK and the US stock markets. Although stock-price-index (SPI) co-movements are established in the long-run, the dynamic analysis based on a fixed rolling window of 160 weeks points out only intermittent episodes of long-run co-movements. Using...

The relationship between fibrinogen to albumin ratio and severity of coronary artery disease in patients with STEMI

Oğuz Karahan, Halit Acet, Faruk Ertaş, Orhan Tezcan, more

The American Journal of Emergency Medicine > 2016 > 34 > 6 > 1037-1042

Previous studies show that serum fibrinogen levels are established risk factors for coronary artery disease (CAD) and that serum albumin levels are of a higher specificity and sensitivity in ST-elevation myocardial infarction (STEMI). In this study, we sought to evaluate the association between fibrinogen to albumin ratio (FAR) and the extent and severity of CAD evaluated by TAXUS Drug-Eluting Stent...

The Implications of Deepening and Widening for EU’s External Economic Relations

Mehmet Ugur

Forschungen zur Europäischen Integration > Erweiterung und Integration der EU > 175-195

For better or worse, the 1990s was the decade of regional integration in Europe and globally. Outside Europe, 50 of the 125 regional integration arrangements (RIAs) concluded after 1945 were concluded between 1990–94. In Europe, the EU went through a deepening process and embarked on a process of enlargement. This paper aims to identify the possible implications of EU’s deepening and widening for...
