Evaluation of effectiveness of cold atmospheric plasma treatment methods for prevention of ventilator-associated pneumonia

İbiş, Fatma

Hospital-acquired infections (HAI) (nosocomial infection) are serious health problems that occur when person acquires infection during stay in a hospital for causes other reasons than that infection. Colonization of microorganisms pave the way for deaths, in detail, Ventilator Associated Pneumonia (VAP) is remarkable in terms of mortality accounted for 15% of nosocomial infections. Ventilator associated pneumonia (VAP) is common a disease, especially among patients that are on connected ventilators in intensive care units. It is defined as the pneumonia, in which occurs in at least 48 h ...Daha fazlası

Control and simulation of swarm mobile robots

Şen, Hayrettin

This thesis presents both control of mobile robots that can move by using collective motion algorithm and simulation of the robots during the motion. The orientation of the robots was controlled remotely by one user during the collective motion. The transmission of orientation data from the remote controller to the robots was done by using XBee modules. The control algorithm of collective motion was developed by using individual-based model. Two modes are considered during the control. These modes are search and swarm mode. The collective motion was performed by robots that are moving with re ...Daha fazlası

Evaluation of passive building design parameters for Izmir city

Güçü, İlker

The housing sector is one of the largest sector responsible for energy consumption in the world and Turkey. Sustainability is an emerging issue as energy related problems arises throughout the world. The sustainable sources are both clean energy sources and mostly renewable. Therefore, especially in terms of economy, these new energy sources are important opportunity for countries dependent on other countries energy. Turkey is rich in sustainable resources and especially Izmir province has good potential in terms of solar, wind and geothermal energy which are the most important sustainable sou ...Daha fazlası

Reproduction and population structure of the sea cucumber Holothuria tubulosa in the Dardanelles Strait (Turkey)

MEHMET ÇULHA | HAKKI DERELİ | SANİYE TÜRK ÇULHA

This study investigated Holothuria tubulosa, Gmelin 1791 in the Dardanelles Strait from April 2013 to March 2014, in order to outline the morphological characteristics, reproductive patterns and the relationship between population characteristics and environmental parameters. 15 to 30 individuals of this species were sampled monthly at three stations. There was a negative allometry between length and weight, with gutted weight being the most reliable measurement for this species. The reproductive patterns of the species were identified for the first time for examples from the Turkish coast ...Daha fazlası

Assessment of trace metal contamination in the sea cucumber (Holothuria tubulosa) and sediments from the Dardanelles Strait (Turkey)

SANİYE TÜRK ÇULHA | HAKKI DERELİ | MEHMET ÇULHA

This study was performed to determine the concentrations of some trace metals (Cd, Cu, Pb, Ni, Zn, and Fe) in Holothuria tubuosa (Gmelin, 1788) belonging to Echinoderm species and in sediments that they live at three different stations (Gelibolu, Umur Bey/Lapseki, and Dardanos) on Dardanelles Strait between April 2013 and March 2014. The mean trace metal concentrations determined in H. tubulosa and sediment were as follows: Cd 0.18 mg/kg, Cu 2.43 mg/ kg, Pb 2.09 mg/kg, Ni 14.58 mg/kg, Zn 16.86 mg/kg, and Fe 73.46 mg/kg and Cd 0.70 mg/kg, Cu 5.03 mg/kg, Pb 14.57 mg/kg, Ni 27.15 mg/kg, ...Daha fazlası

Heavy Metal Accummulation in Muscles and Total Bodies of Mullus barbatus, Trachurus trachurus and Engraulis encrasicolus Captured from the Coast of Sinop, Black Sea

SANİYE TÜRK ÇULHA | MEHMET ÇULHA

The levels of heavy metals viz., Cd, Cu, Fe, Ni, Pb, Zn and Al were determined by ICP-AES in the muscles and total bodies of Mullus barbatus (Linnaeus 1758), Trachurus trachurus (Linnaeus 1758), Engraulis encrasicolus (Linnaeus 1758) captured from the coast of Sinop. The order of the levels of the heavy metals in the total fish samples was Fe > Zn > Al > Pb > Cu > Ni > Cd, whereas in the muscles, the order was Zn > Fe > Cu > Al > Pb > Ni > Cd. The experiment results are discussed by comparison with literature values.

Using alcohol as a carrier producing polyanionic cellulose (PAC) polymer from solid textile waste

Karakuş, Hüseyin

Cellulose is the most abundant organic polymer on earth. It is naturally regenerated by forests and cotton plantations with a speed of 10 billion metric tons per year regularly. Not only its natural reproduction makes it ecologically beneficial but also its biological degradability makes cellulose an ‘eco-friendly material’. Applications of cellulose is limited due to its insolubility in water. Contrarily, its water-soluble derivatives, especially cellulose ethers, are found in nearly all the products we are using in our daily life. Although cellulose is the main raw material for producing ce ...Daha fazlası

Olive leaf powder and boron reinforced polypropylene composites Zeytin yaprağı tozu ve bor katkılı polipropilen kompozitleri

Kara, Hilal

SUMMARYPlastics have a wide application area in our daily life because of the properties such as being inexpensive, lightweight and easy to take shape. Plastics can lead to some problems such as endangering human health and reducing the life of the material, because the plastic surfaces are so available for microorganisms to form a biofim by holding onto the surface easily. Researches for antibacterial materials containing various natural and inorganic substances has been increased and become more important because of that people are often infected by microorganisms such as bacteria, molds, ye ...Daha fazlası

Heavy metals in tissues of scorpionfish (Scorpaena porcus) caught from Black Sea (Turkey) and potential risks to human health

SANİYE TÜRK ÇULHA

Scorpionfish (Scorpaena porcus) is a demersal fish species commercially important for its of which meat is tough and delicious. The aim of this study was to determine heavy metal (Al, Cu, Ni, As, Cd, Hg, Pb, U) concentrations in this fish species which is traditionally consumed in the Black Sea Area and, to compare the concentrations of various toxic elements in different organs of the fish specimens (muscle, liver, gill, and skin). Within this scope, the mineralization was performed using microwave digestion system. Thirty-two scor pionfish caught from Sinop Inland Port during 2010 w ...Daha fazlası
