THE EFFECT OF PULSED ELECTROMAGNETIC FIELDS FOR IN VITRO WOUND HEALING EXPOSURE SYSTEMS
SUMMARY
Electromagnetic fields have achieved important role as stimulator and therapeutic facility in biology and medicine (Blank & Findl, 2013). The effects of low magnitude, low frequency pulsed electromagnetic fields have been a period of study since past few decades, which was mainly on the treating soft tissue injuries, skin ulcers, nonuniform bone fractures and degenerative nerve healing (Hug & Röösli, 2012b). Chronic wounds are a major healthcare problem for patient morbidity and contribute signi ...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
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
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
The scarcity of suitable land for construction of engineering facilities and shortage of natural earth aggregates has highlighted the need for finding innovative way of construction. Nowadays problematic soils such as: soft clay, organic soils and liquefiable soils can be improved to the required civil engineering requirements by application of soil stabilization. Soil stabilization is a method intended to increase or preserve the stability of soil mass and chemical alteration of soil to improve engineering properties.
Generally, ground treatment techniques used are: densification, reinforcem ...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
occurs in at least 48 h ...Daha fazlası
The understanding of sediment transport with fluid in pipes is one of the important issues in hydraulics engineering. If the fluid velocity is lower than a critical value, a stationary cuttings bed develops, which may cause excessive head loss. In this study, a Fuzzy Logic (FL) model is developed to estimate stationary cuttings bed thickness inside the annulus. Experimental data is collected from literature in order to train proposed models. Results showed that the cuttings bed thickness could be estimated using the developed model with a reasonable accuracy when compared with the experimental ...Daha fazlası
The purpose of aggregating rubber is to increase concrete’s flexibility, elasticity, and
capacity to absorb energy. In some application of concrete, it is desired that concrete
should have low unit weight, high toughness and impact resistance. Although
concrete is the most commonly used construction material, it does not always fulfill
these requirements. In order to improve elastic properties of concrete and recycle the
waste materials, new applications have been realized recently. One of these
applications is the utilization of discarded tires in order to use together with
aggregate. ...Daha fazlası
DEVELOPING A NEW UTERINE MANIPULATOR (TRANSVAGINAL UTERUS AMPUTATION DEVICE) FOR TOTAL LAPAROSCOPIC HYSTERECTOMIES IN GYNECOLOGICAL SURGERIES
SUMMARY
Hysterectomy, that is removal of uterus, is one of the most common major operations in gynecologic surgeries. Laparoscopy technique is preferred in hysterectomy because of its advantages such as lower intra-operative blood loss, decreased surrounding tissue/organ damage, less operating time, lower postoperative infection and frequency of fever, shorter duration of hospitalization and post-operative returning time to normal activity. Firstly u ...Daha fazlası
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
