ASSESMENT OF BATHYMETRIC MAPS VIA GIS FOR WATER IN RESERVOIR

In order to adopt measures for storing more water in reservoirs, lakes and ponds; toprevent water pollution, protect water sources and extend the service life of thesefacilities, it is important for manager (Municipalities, Directorates of the StateHydraulic Works (DSHW), Irrigation Unions etc.) to know the current topographicconditions and any changes in the storage capacities of these facilities. This studyaimed to identify the updated topographic and bathymetric data required for theefficient management and usage of Altınapa reservoir, changes in surface area andvolume of the facility, and to form a Reservoir Information System (RIS). Twodigital elevation models, from 2009 and 1984, were used to determine changes inthe storage capacity of the reservoir. The calculations indicated that, within this 25-year period, the storage capacity of the reservoir decreased by 12.7% due tosedimentation. A Dam Information System (RIS) was developed from a wide rangeof data sources, including topographic and bathymetric data of the reservoir and itssurrounding area, data on specific features such as plant cover, water qualitycharacteristics (Temperature, Dissolved Oxygen (DO), Secchi Disk Depth (SDD)and pH), geological structure, average water level, water supplied from springs,evaporation value of the reservoir, and precipitation

Effect of Modified Constraint-Induced Movement Therapy on Upper Extremity Function for Stroke Patients with Right/Left Arm Paresis: A Single-Blind Randomized Controlled Trial

Purpose: Stroke is one of the most common causes of disability because of functional, cognitive, and psychological issues. Motor deficits in the afflicted upper extremity affect about 50% of stroke survivors. This study aimed to evaluate the effects of modified constraint-induced movement therapy (mCIMT) on hemiparetic right/left upper limb functions and quality of life (QOL). Materials and Methods: In this prospective, randomized, controlled and single-blind study, 40 patients were assigned to the right-mCIMT (n=10), left-mCIMT (n=10), and control (n=20). mCIMT was applied 4h/day, 2 weeks, 10 sessions. A conventional rehabilitation program was applied to all patients. Patients were evaluated using the Fugl-Meyer Motor Assessment (FMA), Motor Activity Log (MAL), Stroke Impact Scale (SIS), Box-Block Test (BBT), the number of repetitions in shaping exercises, and the duration of task exercise. Results: There was a statistically significant improvement in the FMA of the left-mCIMT group (p=0.040). Both mCIMT groups showed statistically significant improvements in the MAL-amount of use (AoU) and MAL-quality of use (QoU), the number of repetitions in the shaping exercises, and the BBT (p<0.05). The activity of daily living, hand function, and stroke recovery domains of the SIS were increased significantly in both groups (p<0.01). There was a statistically significant increase in the strength domain of the SIS in the left-CIMT group (p=0.037). Conclusions: mCIMT was effective in improving motor functions, dexterity, and QOL in patients with right/left arm paresis. These positive effects continued for 3 months. Although left mCIMT had a positive effect on arm motor impairment, further research is needed

This thesis proposes the utilization of magnetic levitation for designing an acceleration sensor, taking the advantage of up-to-date contactless displacement sensing technology. The accelerometer is expected to have long-term robustness by isolating the proof mass from the rest of the accelerometer body, virtually eliminating mechanical friction and wear. Furthermore, levitated sensors have a great potential to achieve high precision. In this context, this study presents designing a levitated accelerometer, which suspends the proof mass and controls its position relative to the sensor body. When the sensor body moves, the shift of the proof mass with respect to the sensor body is detected and the control system produces feedback forces on the proof mass to keep the proof mass stationary with respect to the sensor body. In this study, a magnetically levitated accelerometer is designed, constructed and tested. Permanent magnets are used to offset the weight of the levitated proof mass. However, that is not enough to keep it steady and stable afloat. Hence, active magnetic actuation is utilized not only for levitation but also for position control of the proof mass. In the design phase, a mathematical model of the system is developed and a simulation model is built by using MATLAB®/Simulink®. Magnetic analyses are performed by using finite element method. PID controllers run independently in a digital microcontroller for position control in two axes and two rotations. Eddy current sensors are installed on the system to measure the relative position along those axes. Moreover, motor drivers are used to feed the proportional current to electromagnets and evaluate the current values on the solenoids by built in sensors. Tests are conducted in order to tune the controllers and finally compare the acceleration measurements with a commercial sensor. The measurement limit of accelerometer is measured as ± 0.6 g. Bias instability and velocity random walk values is calculated as 0.174 mg and 0.182 m/s/√h respectively.Thesis (M.S.) -- Graduate School of Natural and Applied Sciences. Mechanical Engineering

Tooth eruption and symptomatology: Are the symptoms assumed to be related to the tooth eruption really associated with teeth?

Despite little evidence, many various complaints might be associated with teething in children. Symptoms related with teething mostly result in delay diagnosis of underlying disease. In this study we explore the relationship between teething and symptoms commonly seen in pediatric clinics. Children less than 36 months of age, who came to Medipol University Faculty of Medicine, between October 2013 and May 2014 for routine well-child visit, were recruited in the study. At visit time 318 infants (60.5%) had one or more visible tooth eruption. Participants were divided in five subgroups according to their age. Parents of infants (mean age 11.5 months) completed questionnaires. The most commonly reported symptom was irritability in 12-18 months (74%), 24-30 months (57%) and 30-36 (44%) months’ periods, drooling in 6-12 months (87%), loss of appetite in 18-24 months (64%). Irritability was statistically significant in all groups except 18-24 month. (p=0.54). Febrile fever was only statistically significant in 6-12 and 12-18 months groups. Increase in biting was become statistically significant after 12 months. Although rates vary according to age group, many mild symptoms previously thought to be associated with teething were found temporally correlated with teething. Before parents/caregivers attribute these symptoms to tooth eruption other possible causes must be ruled out. © 2015, Yuzuncu Yil Universitesi Tip Fakultesi, Universitas Indonesia.

Clinical and molecular evaluation of MEFV gene variants in the Turkish population: a study by the National Genetics Consortium

Familial Mediterranean fever (FMF) is a monogenic autoinflammatory disorder with recurrent fever, abdominal pain, serositis, articular manifestations, erysipelas-like erythema, and renal complications as its main features. Caused by the mutations in the MEditerranean FeVer (MEFV) gene, it mainly affects people of Mediterranean descent with a higher incidence in the Turkish, Jewish, Arabic, and Armenian populations. As our understanding of FMF improves, it becomes clearer that we are facing with a more complex picture of FMF with respect to its pathogenesis, penetrance, variant type (gain-of-function vs. loss-of-function), and inheritance. In this study, MEFV gene analysis results and clinical findings of 27,504 patients from 35 universities and institutions in Turkey and Northern Cyprus are combined in an effort to provide a better insight into the genotype-phenotype correlation and how a specific variant contributes to certain clinical findings in FMF patients. Our results may help better understand this complex disease and how the genotype may sometimes contribute to phenotype. Unlike many studies in the literature, our study investigated a broader symptomatic spectrum and the relationship between the genotype and phenotype data. In this sense, we aimed to guide all clinicians and academicians who work in this field to better establish a comprehensive data set for the patients. One of the biggest messages of our study is that lack of uniformity in some clinical and demographic data of participants may become an obstacle in approaching FMF patients and understanding this complex disease
