    (Aksaray Üniversitesi, 2018) Çelik Ertuğrul, Duygu; Zontul, Metin; Bitirim, Yiltan; Taymaz, Gökhan
    This study introduces the Remote Medical Tracking Mobile System (TrackARTI) which guides parents or health expert users in the treatment of Acute Respiratory Tract Infections (ASYE) diseases for children aged 0-6 years. The main purpose of this system is to gather actual data belonging to the medical cases of ASYE period in various environments instantly, to display them when requested, to store them in structural form in order to understand by machines, to deduce the data through its retrieval mechanism and to make personalized medical suggestions or to present relevant new data inferred. The main user group of the system is pediatric specialists and parents. The main stakeholders of this system are parents, child patients, pediatric specialists and health personnel. The proposed TrackARTI system is an example of intelligent M-Health systems. The system has two basic outputs: TrackARTI Artificial Intelligence based Inferencing Mechanism and TrackARTI Mobile Application. In addition, the Artificial Intelligence based Inferencing Mechanism of the system involves two main activities in itself; 1) Medical Image Processing based Inferencing and 2) Semantic Web Based Inferencing of new medical data and suggestions through its Inference Rules.

    Gaussian modified pell sequence and gaussian modified pell polynomial sequence
    (Aksaray Üniversitesi, 2018) Yağmur, Tülay; Karaaslan, Nusret
    In this paper, we first define the Gaussian modified Pell sequence, for n ? 2, by the relation = 2 + with initial conditions = 1 ? i and = 1 + i. Then we give the definition of the Gaussian modified Pell polynomial sequence, for n ? 2, by the relation = 2 + with initial conditions = 1? xi and = x + i. We give Binet’s formulas, generating functions and summation formulas of these sequences. We also obtain some well-known identities such as Catalan’s identities, Cassini’s identities and d’Ocagne’s identities involving the Gaussian modified Pell sequence and Gaussian modified Pell polynomial sequence.

    Optimization of combined Ozone/Fenton process on olive mill wastewater treatment
    (Aksaray Üniversitesi, 2018) Kırmacı, Aslıhan; Duyar, Ahmet; Akgül, Vildan; Akman, Dilek; Cırık, Kevser
    The aim of this study was to investigate the applicability of Fenton process and combined ozone/Fenton process to remove color, soluble chemical oxygen demand (CODs), phenol, and dissolved organic carbon (DOC) from real olive mill wastewater (OMW). The treatability of OMW was investigated in three different study parts. Initially, Fenton process was optimized under varying H2O2/Fe2+ molar ratios ranging between 10 and 20 at the constant H2O2 concentration of 0.5 mM. The H2O2/Fe2+ molar ratio of 10 was found optimum providing high color (51.6 %), CODs (58%), DOC (27.9%) and phenol removals (93.9%). Further, combined ozone/Fenton process was applied under gradually increasing dosages of Fe2+ and H2O2 reagents at constant H2O2/Fe2+ molar ratio of 10. The high color removal efficiency (51.6% color removal for Pt-Co) was obtained at the H2O2 and Fe2+ molar ratio of 0.5/0.05. Additionally, CODs, color, DOC and phenol removal efficiencies improved at increasing reagents concentrations. However, the color removal efficiency was adversely affected while no significant difference on CODs and phenol removal was observed at higher concentrations of molar concentrations above 0.5/0.05. Additionally, the results indicated that combined process enhanced treatment performance of OMW by 21%, 49% and 22% in terms of color, DOC and CODs removals, respectively, compared to only-Fenton process. In the rest of this study, combined ozone/Fenton process was optimized under varying ozonation time (60-120 min) at the optimum H2O2 and Fe2+molar dosage of 0.5/0.05 obtained from previous parts. Ozonation time significantly affected the treatment performance, and optimum the reaction time was determined as 90 minute in terms of the high treatment productivity and low operating cost resulted from minimum ozone consumption and short reaction time.

    Antimicrobial and Antioxidant evaluation of fruit extract from Cornus mas L.
    (Aksaray Üniversitesi, 2018) Yiğit, Demet
    In this present study, water and methanol extracts of Cornelian cherry fruits (Cornus mas L.) were studied for evaluating of antioxidant and antimicrobial properties. The antioxidant properties were evaluated by determination of 2,2-Diphenyl-1-picrylhydrazyl (DPPH) radical scavenging ability and lipid peroxidation inhibition activity. Also total phenolic contents of the extracts were detected by Folin method. The extracts of the fruits have antioxidant potential. The DPPH radical scavenging activity was higher in water extract (36.6 %) than the methanol extract (30.6 %). Unlike, methanol extract of fruits have more activity (18.9 %) than water extract (16.7 %), also with higher phenolic compound contents. Antimicrobial activities of above extracts were also tested against 93 clinical isolates of human pathogenic strains belonging to 5 bacteria (Entorobacter aerogenes, Escherichia coli, Proteus mirabilis, Pseudomonas aeroginosa, Staphylococcus aureus) and 5 yeast species (Candida albicans, Candida glabrata, Candida krusei, Candida parapisilosis, Candida tropicalis) by diskdiffusion method. The results showed cornelian cherries are potentially rich source of antimicrobial agents. The most effective antibacterial activity was expressed by methanol and water extract of cornelian cherry fruit against S. aureus with 25 mm inhibition zone and 0.156 mg/ml Minimum Inhibitory Concentration (MIC) value. Only methanol extracts of the fruit have antifungal activity against tested human pathogen clinic isolates.

    Some microbiological properties in soil samples taken from maize grown fields in Sanliurfa
    (Aksaray Üniversitesi, 2018) Küçük, Çiğdem; Cevheri, Cenap
    The aim of this study was to investigate some microbiological properties in soil samples taken from maize grown fields in Sanliurfa. Also, some physic-chemical properties of these soil samples were observed. The soil samples were taken from 0-20 cm depth of maize grown soils. The microbial biomass carbon content of soils was determined as 98.2-198.5 mg C/g dry soil. The enzyme activities studied of soil samples were urease, catalase, dehydrogenase, alkaline phosphatase, ?-glucosidase. Enzyme activities of samples were differently. Positive and negative correlation were found between soil properties observed.

    Tek şerefeli yığma minarelerin deprem davranışı ve dinamik analizi
    (Aksaray Üniversitesi, 2018) Ural, Ali; Çelik, Tülin
    Minareler, Müslümanları namaza çağırmak için İslam dininin ibadet yeri olan camilere bitişik olarak inşa edilmiştir. Türkiye’de ve diğer Müslüman ülkelerde yığma minarelerin büyük çoğunluğu orta şiddetli bir deprem ya da hafif şiddetli bir rüzgâr etkisiyle zarar görebilmektedir. Bunun nedenlerinden biri bu yapıların ince ve uzun olmasıdır. Bir diğer sebebi ise özellikle günümüzde inşa edilen minarelerin herhangi bir mühendislik bilgisi olmadan yapılmasıdır. Bu çalışmada, Aksaray il merkezinde yer alan tek şerefeli 7 adet yığma minarenin deprem davranışları incelenmiştir. Bahsedilen minarelerin geometrik ölçümleri fotogrametrik cihazlar kullanılarak yapılmıştır. Sonlu Elemanlar Metodunu kullanan LUSAS programı ile minareler modellenerek deprem analizleri yapılmıştır. Yapısal analizler birbirleriyle karşılaştırılarak elde edilen sonuçlar yorumlanmıştır.

    Investigation of high temperature effects on concrete additive antifreeze
    (Aksaray Üniversitesi, 2018) Bekem Kara, İlknur; Arslan, Metin
    The purpose of this work is to determine the effect of the antifreeze additive on the behavior of the concrete under high temperature. For this purpose, two different types of C20 class concrete were produced with reference and antifreeze additive. Fresh concrete was poured into plate molds, after 14 days standard curing, core samples of Ø5x10 cm dimensions were taken from plaque concrete. On day 90, the core samples were exposed to temperatures of 20, 200, 400, 550 and 700 °C for 3 hours and they cooled by air and water spray. Experiments on water absorption, ultrasound transit speed and compressive strength were carried out on the core samples. Microstructures were analyzed by X-ray diffraction method in concrete specimens applied at temperatures of 20 and 700 °C. As a result, it has been determined that the concrete with antifreeze strain that is least affected by the temperature of 700 °C is cooled water.
