Energy Supply Chain and Energy Security

ÖZKAN NESİMİOĞLU, Şerife

Energy Supply Chain and Energy Security Şerife Özkan Nesimioğlu Correspondence: serife.ozkan.nesimioglu@karatay.edu.tr In general, supply chain security is a prominent part of energy security, which is defined as “uninterrupted availability of energy sources at an affordable price” by International Energy Agency (IEA). In more detail, energy security can be separated into two sub-definitions as short and long- term energy security. Short term energy security focuses on the ability of the energy system to react promptly to sudden changes in the supply- demand balance. Here, sudden changes refer ...Daha fazlası

Forecasting of solar radiation using different machine learning approaches

DEMİR, Vahdettin | ÇITAKOĞLU, Hatice

In this study, monthly solar radiation (SR) estimation was performed using five different machine learning-based approaches. The models used are support vector machine regression (SVMR), long short-term memory (LSTM), Gaussian process regression (GPR), extreme learning machines (ELM) and K-nearest neighbors (KNN). Modeling of these approaches was carried out in two stages. In the first stage, VIF analysis was carried out to develop the model. Thus, the input parameters that decrease the performance of the model are removed. In the second stage, remaining input parameters such as meteorological ...Daha fazlası

Numerical modeling of Samsun Mert River floods

ÜLKE, Aslı | BEDEN, Neslihan | DEMİR, Vahdettin | MENEK, Necati

Floods are considered one of the most important natural disasters after earthquakes in Turkey. As a result, there is currently great public interest in this issue and it is necessary to intensify research activities in order to understand natural disasters better and to reinforce risk management. The effect of climate change on meteorological events causes an increase in extreme events such as excessive precipitation in some regions. An extreme natural event becomes a disaster when it has a large impact on human settlements and activities. Study area Samsun city is placed in the north of Turke ...Daha fazlası

Informal Breast Milk Sharing in a Muslim Country: The Frequency, Practice, Risk Perception, and Risk Reduction Strategies Used by Mothers

ONAT, Güliz | KARAKOÇ, Hediye

Turkey is the first and only Islamic country which has initiated a process to establish a milk bank. However, the effort was abandoned because of religious concerns. Informal breast milk sharing has become a practical alternative to some. Research Aims: To document the religious concerned views and attitudes toward breast milk sharing and to determine risk reduction strategies of mothers in an Islamic country. Materials and Methods: Participants comprised volunteers from relevant forums or members of social media groups on the Internet. The participants (n = 435) were divided into three groups ...Daha fazlası

tBackground: mecA is a predefined gene causing methicillin resistance in Staphylococcus aureus (S. aureus)isolates; however, it has been shown that some methicillin-resistant S. aureus (MRSA) strains do notcarry this gene. Recently, in isolates found to be MRSA-positive but mecA-negative, a new resistance gene called mecC, which is a homolog of mecA, has been reported. This study aimed to investigate the mecCand mecA genes in MRSA strains isolated from different geographic regions in Turkey.Methods: The sample of the study consisted of 494 MRSA strains isolated from seven geographical regionsi ...Daha fazlası

Flood Modeling of Samsun/Atakum Region by GIS Tools

BEDEN, Neslihan | DEMİR, Vahdettin | ÜLKE KESKİN, Aslı

Study area Samsun/Atakum province is almost under threat of flooding in each year. In this region, the main reason of devastating flood is the influence of the Degirmen stream especially during March, April, and July and due to seasonal rainfall, which eventually makes the district vulnerable to flooding. In addition, the human-based constructions and the collapse of water retaining structures are among the main causes of flooding. In this study flood risks of Samsun Degirmen stream determinate by MIKE 11 and GIS. Numerical model selection for studies provides advantages in developing and chan ...Daha fazlası

Developing numerical equality to regional intensity–duration–frequency curves using evolutionary algorithms and multi‑gene genetic programming

ÇITAKOĞLU, Hatice | DEMİR, Vahdettin

This study aims to carry out regional intensity−duration−frequency (IDF) equality using the relationship with IDF obtained from point frequency analysis. Eleven empirical equations used in the literature for seven climate regions of Turkey were calibrated using particle swarm optimization (PSO) and genetic algorithm (GA) optimization techniques and the obtained results were compared. In addition, in this study, new regional IDF equations were obtained for each region utilizing MultiGene Genetic Programming (MGGP) method. Finally, Kruskal–Wallis (KW) test was applied to the IDF values obtained ...Daha fazlası

Determination of COVID-19 Phobia Level in Health Care Workers

YAVUZ BAŞKIRAN, Deniz | BAYIR, Berna | PEHLİVAN, Erkan

The aim of this study is to determine the COVID-19 phobia level in healthcare workers. The socio-demographic characteristics form and the Coronavirus 19 Phobia (CP19-S) Scale were used as data collection tools. The surveys were shared online on social media. 467 healthcare workers who agreed to participate in the study were reached. Employees who got 55.30 ± 14.64 points from the scale total scores and university graduates were found to have an average of 55.51 ± 14.11, and their families averaged 57.84 ± 15.05. As a result, it was determined that the COVID-19 phobia levels of healthcare worke ...Daha fazlası

Terrorism and Tourism: An Empirical Exemplification of Consequences of Terrorist Attacks on Tourism Revenues in Turkey

KAYA, Mustafa Göktuğ | ONIFADE, Stephen Taiwo | AKPINAR, Ayhan

The booming tourism sector in Turkey has resulted in major economic gains in terms of direct revenues to both government and private sectors alike. Turkey had more than 45 million visits in 2018, and top inbound arrivals were from Russia and European Union (EU) members, such as Germany, the United Kingdom, and Bulgaria, among others (Organization for Economic Co-operation and Development [OECD], 2020). However, terrorism is becoming a challenge to tourism development. This study explores terrorism–tourism dynamics in Turkey. The short- and long-run impacts of terror attacks on tourism revenues ...Daha fazlası

Systematic review of mycotoxins in food and feeds in Turkey

ÜNÜSAN, Nurhan

Mycotoxins are toxic natural contaminants of food and feeds and are produced by various fungi fromAspergillus,Alternaria,Fusarium, andPenicilliumgenera. Molds and their toxins have attracted much attention worldwide dueto the important economic losses related to their effects on human health and domestic and international trade.Although more than 400 mycotoxins have been identified, most studies have focused on aflatoxins, ochratoxin A,fusarium toxins, zearalenone, patulin, and trichothecenes owing to their relationships with food safety andeconomic losses. In Turkey, the dramatic variations i ...Daha fazlası
