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
Audiometry is the technique to identify the nature of hearing loss and to determine the threshold of hearing by recording responses of the patient after presenting him with auditory stimuli with varying intensity levels. There are different audiometric techniques and procedures used for achieving this. The vast majority of medical devices found in the marketplace as a commercial product for the field of audiology have been developed for clinical limited testing. These devices cannot be used for purposes other than those specified by the manufacturer. This has serious limitations in the experim ...Daha fazlası
Urban regeneration greatly affect marginalized groups both across the world and in Turkey and therefore it is a hot topic in the public discussions of urban context. One of those marginalized groups are Roma communities. Their neighborhoods, particularly inner urban areas, face social and physical decay due to discrimination against Roma communities. To address these social and physical problems, urban regenerations projects have been launched in Turkey in the name of improving life standards of Roma citizens. However, implementations could not go further than improving physical conditions of ...Daha fazlası

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

Photocatalytic degradation and complete mineralization of toxic organic compounds in water, soil, and air in the presence of semiconductor materials have received much attention over the last decades. Electronic structure of semiconductors is characterized by a filled valence band and an empty conduction band. When the semiconductor is irradiated with light of sufficient energy corresponding to or exceeding its band gap, an electron is promoted into the conduction band, leaving a hole in the valence band. The electrons and holes are good reductants and powerful oxidants, respectively, and they ...Daha fazlası
