Congenital nasolacrimal duct obstruction (CNLDO) is a common disorder that affects approximately 6-20% of children in the first year of their life. Here we present a case of bilateral congenital dacryocystoceles infected with Serracia marcescens. A 50 day old …

Periodontal hastalıklara ve temporomandibular eklem bozukluklarına neden olan, ağız diş sağlığını etkileyen, çürük oluşumunu arttıran maloklüzyonun, psikolojik, kültürel ve sosyal yönleri, ağız-diş ve genel vücut sağlığının ayrılmaz bir parçası olarak görülmek…

The study area covers Kaz Mountain and its surroundings which is located in the north of Güre, Çamlıbel and Arıtaşı Neighborhoods of Edremit District of Balıkesir Province. The Kazdağ Massive which is estimated to be of Paleozoic primitive age starts with the …

Endokrin bozucu kimyasallar; endokrin sistem fonksiyonlarını etkileyerek organizmada ve organizmanın nesillerinde olumsuz sağlık etkileri oluşturan ekzojen madde veya madde karışımlarıdır. Bu maddeler doğal hormonların faaliyetlerini değiştirebilmektedirler ve…

The study of various mathematical problems (such as elasticity, non-Newtonian fluids and electrorheological fluids) with variable exponent growth condition has been received considerable attention in recent years. These problems are interesting in applications…

The Korovkin theory has effective role in approximation theory. This theory is connected with the approximation to continuous functions by means of positive linear operators. Many mathematicians have investigated the Korovkin-type theorems by for a sequence of…

Sulak alanlar dünyanın her yerinde olduğu gibi ülkemizde de hem ekolojik hem de ekonomik değere sahiptir. Bulunduğu bölgede doğal dengeyi sağlayan sulak alanlar aynı zamanda içerisinde barındırdığı güzel manzara, hassas kuş türleri, endemik bitkiler sayesinde …

In this study, a PID controller with fractional order derivative filter (PIDFF) is designed for automatic voltage regulation (AVR) in power systems. In order to ensure maximum transient and steady state performance from the designed controller, the controller …

The U-shaped assembly line balancing (UALB) problem has been extensively investigated in the existing academic literature. However, only a limited number of studies consider the uncertainty in the assembly lines. In this research, a robust formulation is devel…

Turkey is not possible in the existing forest roads with very little of the superstructure and the remaining majority uncoated and transport of wood raw material in an expeditious manner in all seasons due to the unfounded nature of the soil in the road. For t…

In the study carried out in Erzurum Olur micro-catchment, the sediment measurement station installed by the Coruh River Rehabilitation Project was used to  calculate the amount of suspended solids from the basin. There is an automatic water sampler device and …

Sediment can be composed of all road elements. On soil roads, road surface erosion is generally the predominant source of sediment. The multifaceted impact of forest road construction on the environment is always a serious issue in terms of watershed managemen…

The existence of healthy, natural ecosystems and the continuation of the basic services in the ecosystem are essential for the protection of consumable resources. Pollination is one of these basic services. The effective pollination of plants is a key action f…

Nanotechnology is the science of controlling materials at the atomic and molecular levels. With the use of nanomaterials for diagnostic and therapeutic purposes, the field of molecular nanotechnology has emerged, enabling nanoelectronic biosensors and individu…

High temperature superconductors (HTSs) have been widely used in magnetic bearing systems, magnetically levitated transportation systems (Maglev), superconducting motors, etc. due to their stable levitation properties. Although the studies on Maglev systems ha…

Complex-valued artificial neural network (CVANN) has been developed to process data with complex numbers directly. In a CVANN the weights, threshold, inputs and outputs are all complex numbers. The convergence of the CVANN back propagation algorithm depending …

Korovkin type approximation theorems have very important role in the approximation theory. Many mathematicians investigate and improve these type of approximation theorems for various operators defined on different spaces via several new convergence methods. T…

In this study, the impregnation of Lareks wood with borax and nanotechnological varnish at various vacuum / diffusion times according to ASTM 1413-76 standards and the changes on technological properties were investigated. Pressure resistance properties were d…

One of the most well-known and easy-to-design converter of DC-DC converters is DC-DC Boost converter. DC-DC boost converters are widely utilized in industrial applications. Therefore, output voltage regulation of the boost converter is a popular issue that res…

It is important to determine the initial level of failures of induction motors used in many industrial applications. The sudden stops of the system can be prevented with the pre-detection of the fault. The experiment mechanism was established to detect mechani…
