Heavy metals in Mytilus galloprovincialis, suspended particulate matter and sediment from offshore submerged longline system, Black Sea

SANİYE TÜRK ÇULHA

The study was performed between March 2009 and March 2010 at the Sinop Inner Harbor on cultured mussels at the offshore submerged longline system. The samples of mussels, sediment and suspended particulate matter were seasonally taken for the purpose of monitoring differences of metal contents. In addition, burnable organic matter, contamination factors (CF), pollution load index (PLI) in sediment samples, meat yield of mussels were seasonally determined. All metals in suspended particulate matter were found to be above the national limit. Cd concentration in sediment was above the l ...Daha fazlası

Social media analysis based on mobile systems

Yavuz, Levent

The use of internet and social media has increasing with the developing new technologies and large number of people have actively using of the internet. At the same time the development of mobile technologies and the widespread usage of the mobile devices that can be shown as the reason for that. In this way, social media has become a virtual environment in which people interact with each other. Some of social media platforms such as Twitter have become very popular and most of people share some information about themselves on these platforms. They also share their ideas, thoughts, live ...Daha fazlası

Characterization of Clay brick materials produced with red mud and nut shell wastes for building applications

Çam, Ata Sadık

In this study, clay based brick with micro pores was developed for thermal insulation in the building materials. Turkey produces about 70% of the world hazelnut production. The aim of this thesis is to reduce the thermal conductivity coefficient by adding organic waste (hazelnut shell) into clay mixture to form porosity during firing of clay bricks. Moreover, it is to maintain the similar mechanical properties by adding inorganic waste (red mud) into clay mixture. The development of a highly porous bricks with applicable mechanical strength will contribute to save energy in the building ...Daha fazlası

A preliminary offshore wind energy potential study for bay of İzmir: Quantifying the airflow distortion on local ferryboats for adjustment of wind data by 3D CFD analyses

Güngör, Şahin

Humankind have an interest to obtain marine meteorological data for decades, therefore, constant and mobile meteorological stations have been used for the correct measurements. These meteorological data include wind speed and direction, sea surface and air temperature and cloud cover. Ship-mounted anemometers have been used for meteorological observations, obtaining the wind speed data and climate change analysis. Wind data are especially gathered and reported by Voluntary Observing Ships (VOS). World Meteorological Organization (WMO) created the VOS program to ensure reporting of the wind dat ...Daha fazlası

Modelling, Analysis and Experimental Verification of Pneumatic Brake System

Güleryüz, İbrahim Can

As the technology develops, the development in vehicle safety becomes an area, which takes the attraction of the researchers who are working in automotive industry. Although systems like air bag system, lane departure warning system (LDWS) and tire pressure monitoring system (TPMS) improve the safety of the vehicle, main studies, in which advanced technology is used mostly focus on the brake system including anti-lock braking system (ABS), traction control system (TCS), electronic stability control (ESC), advanced emergency braking system (AEBS), adaptive cruise control (ACC). Thus, det ...Daha fazlası

The evaluation of innovative insulation materials for energy efficiency in civil engineering

Thermal insulation term is the most important measure that provides the thermal comfort which human being has been looking for as a natural habit from the first residential lifestyle begins. The inventions in this topic, especially has been arisen in last centuries and specifically in the last century it has been carried forward and both aesthetic and performance based products have been researched to be discovered. In the light of researches each in academic and practical fields, the hope of this demand to be provided is increased via innovative insulation materials. Accordingly, to c ...Daha fazlası

Development of vibration performances of hybrid laminated composite materials by using stochastic methods

In recent years, laminated composites are fairly utilized in marine, automotive, aerospace, military and other engineering applications because of their high specific modulus (ratio between the young modulus and the density) and high specific strength (ratio between strength and density). In addition to these features, fiber reinforced composites have inherent tailorability such as fiber orientation and stacking sequence and provide great possibilities to designers against isotropic materials. Determination of the fundamental frequency performance of laminated composite plate is crucial for th ...Daha fazlası

Nonlinear analysis of steel frames considering lateral Torsional buckling effect

The use of nonlinear analysis methods is widely preferred to determine the realistic behavior of the structures through the computer technologies developed in recent years. However, the stability problems that significantly affect the structure behavior are often neglected in nonlinear analysis and in computer programs that are frequently used to the realization of these analyses. Lateral torsional buckling behavior, which is one of the stability problems, is considered to be neglected in many studies using nonlinear analysis methods in the literature. As a result, the realistic behavior ...Daha fazlası

Detection of dyes in water using smartphone technology for environmental sustaınability

Kocakuşak Özdemir, Gizem

The goal of this thesis is to develop the applicability of an ultra-low cost, field-deployable, plastic fiber based smartphone spectrometer system to study dye adsorption from water. A custom cradle using smartphone’s built-in flash and camera was designed for visible absorbance spectroscopy without any need for external electrical components. We firstly investigated the performance of smartphone spectrometer for methylene blue (MB) absorbance in water with a detection limit of 0.5 ppm, and compared it to that of a commercial spectrometer. We elaborated on the contribution of image formats to ...Daha fazlası

Technical investgation for the use of textile waste fiber types in new generation composite plasters

Kalkan, Şevket Onur

Garment and textile production industry is one of the main sectors of our country. This sector is a major driving force in our developing economy. According to 2014 data, Turkey is the third country on textile export among the European countries. Besides, Turkey is the world's sixth largest garment exporter. With such a huge production power, in Turkey’s textile sector, waste and/or residual textile materials are composed depends on the large scale production, as in most of the other production sectors. Such waste materials in textile industry are the left materials from production stag ...Daha fazlası
