Akar, Zeynep; Burnaz, Nesibe Arslan
Cupric reducing antioxidant capacity (CUPRAC) method is one of the most widely used antioxidant methods. However, its need for a spectrophotometer, as in many other methods, is an important disadvantage. Cupric reducing antioxidant capacity was determined based on color analysis with Image J program in computer with the new method developed in this study and thus, use of spectrophotometer was eliminated. The new colorimetric CUPRAC assay was applied to various standard antioxidants and plant extracts. The reaction mixtures were dropped on TLC plate. The colors formed on TLC were transferred to the computer by using scanner images, and CTEAC value in μmol/L of each sample was determined with the image J program. The CTEAC values were compared with the TEAC values measured with the spectrometric method. A linear relationship was found between both (C)TEAC values of antioxidant standards (R2 = 0.991) and plant extracts (R2 = 0.994). Thus, the new method developed for the CUPRAC antioxidant assay can be easily performed in any environment without spectrophotometer device, and it is a low-cost method.

Albayrak, Seyda; Genc, Berna; Ozkan, Hakan; Taskin, Mesut; Adiguzel, Ahmet
In this study, one hundred and thirty isolates were isolated from water and sludge samples taken from hot springs located in different regions of Turkey. Among them, eleven isolates were chosen according to conventional (morphological, physiological and biochemical tests) and molecular methods (rep-PCR and 16S rRNA sequencing). These bacteria were then tested for their capability to produce valuable enzymes. As a result; species belonging to Bacillus, Anoxybacillus, Aeribacillus, Enterococcus, Exiguobacterium and Paenibacillus were identified. Test strains were found to have optimum reproductive potential at pH 5.0-9.0 and 15-65°C, usually at a concentration of 1.0-10.0% (w/v) NaCl. In addition, all thermotolerant bacteria were Gram, endospore (except E. profundum), catalase and oxidase (except E. faecium and E. profundum) positive, and rod-shaped (except E. faecium). It was observed that all isolates had a 99% similarity percentage as a result of 16S rRNA sequence analysis. All of the isolates were capable of producing industrially important enzymes moreover, eight of them could produce at least two of these enzymes. Test strains had high potential of industrial enzyme production, and the enzymes from these thermo-tolerant isolates will be widely used in biotechnological processes.

In the opinion of these authors, technology alone can never give an organization an edge over competitors or provide an industry step change. However, history has shown that technology applied with correct logistics and strategy makes a significant difference. Never has the minerals industry faced such daunting challenges and been in such need of a step change. Application of autonomous systems has been steadily increasing in the minerals industry. Automation technology has changed the mining value chain from exploration to mineral processing and refining. The future state will only see additional in-roads of automation into more processes and the whole system design. To better understand the near-future potential of automation, it is useful to explore and review the current state of automation in minerals development. A review of the state of automation research is given. The review will consider three critical areas: automation technology, system’s engineering and management processes around automation, and the role of human factors engineering in automated and semi-automated systems. The review ends with a discussion on the social and political risks of automation in terms of shared value and sustainable development.

Rogers, W. Pratt; Kahraman, M. Mustafa; Dessureault, Sean
The mining industry is adapting data-rich technology. Data management processes and infrastructure require additional investment which, can be difficult to justify. A valuation model for data management infrastructure would necessitate modelling the ‘use’ of data and quantifying the value and the likelihood of success of improvement initiatives. A model is presented which can assess the impacts of a data-driven initiative. The initiatives are shown to be the foundation of improved shift coordination resulting in significant and sustained operational improvements. This paper aims to illustrate the value of using data from source systems in mining operations.

This study covers a highest-luminosity high-energy lepton collider (FCC-ee) and an energy-frontier hadron collider (FCC-hh), which could, successively, be installed in the same 100 km tunnel. The scientific capabilities of the integrated FCC programme would serve the worldwide community throughout the 21st century. The FCC study also investigates an LHC energy upgrade, using FCC-hh technology. This document constitutes the second volume of the FCC Conceptual Design Report, devoted to the electron-positron collider FCC-ee. After summarizing the physics discovery opportunities, it presents the accelerator design, performance reach, a staged operation scenario, the underlying technologies, civil engineering, technical infrastructure, and an implementation plan. FCC-ee can be built with today's technology. Most of the FCC-ee infrastructure could be reused for FCC-hh. Combining concepts from past and present lepton colliders and adding a few novel elements, the FCC-ee design promises outstandingly high luminosity. This will make the FCC-ee a unique precision instrument to study the heaviest known particles (Z, W and H bosons and the top quark), offering great direct and indirect sensitivity to new physics.

Çamur, Emre; Coskun, Alper; Kavukoglu, Ovunc; Can, Utku; Kara, Onder; Çamur, Arzu Develi; Sarica, Kemal; Narter, Kamil Fehmi
Introduction: Gleason Score (GS) upgrading rates in the literature are reported to be around 33-45%. The relationship between prostate volume and GS upgrading should be defined, aiming to reduce upgrading rates in patients with low risk groups who are eligible for active surveillance (AS) or minimally invasive treatment, by varying biopsy cores, or lengths of cores according to prostate volumes. In this regard, the aim of our study was to establish the relationship between prostate volume and GS upgrading. Materials and methods: We retrospectively analyzed the medical records of 78 patients, who were appropriate for AS between 2011-2016 at our hospital. Inclusion criteria were patient age under 65 years, PSA level under 10 ng/ml, GS (3 + 3) or (3 + 4), and 3 or less positive cores, clinical stages <= T2. GS increase in radical prostatectomy specimen was considered as 'upgrading' and in addition, score reported by biopsy as 3 + 4 but in surgical specimen as 4 + 3 were also considered as 'upgrading'. The effect of prostate volume on Gleason grade upgrading was examined by calculating upgrading rates separately for patients with prostate volume 30 ml or less, those with 30 to 60 ml, and those over 60 ml. Results: As a result of the analysis of the data, upgrading was seen in 35 (44.8%) of 78 patients included in the study. In the cohort mean prostate volume was 49.8 (+/- 26.3) ml. Twenty-two patients (28.2%) had prostate volume 30 ml or less, 34 (43.6%) 30 to 60 ml, and 22 (28.2%) 60 ml or more. The patients were divided into two groups as those with and without GS upgrading. Between the groups prostate volume and prostate volume range (0-30/31-60/> 60) were not significantly different (p value > 0.05). Conclusions: Gleason grade upgrading causes patients to be classified in a lower risk group than they actually are, and may lead to inappropriate treatment. This condition has a direct effect on the decision of active surveillance. Therefore, it is important to define the factors that can predict GS upgrading in active surveillance appropriate patients. In this study, we found that prostate volume has no significant effect on upgrading in active surveillance appropriate patients.

Ethanolic (EEC) and aqueous (WEC) extracts of cinnamon (Cinnamomum verum) were evaluated for their antioxidant profiles by eight distinguished bioanalytical antioxidant methods. Their inhibitory effects were tested against some enzymes including acetylcholinesterase, butyrylcholinesterase, alpha-glycosidase and alpha-amylase, which linked to different diseases. Additionally, the antioxidant properties were determined and polyphenolic compositions of the both extracts were evaluated by LC-MS/MS analysis. According to the LC-MS/MS experiments, thirteen compounds were found in WEC and EEC. Also, p-hydroxybenzoic acid (321.1 mg/kg extract), p-coumaric acid (291.4 mg/kg extract), and pyrogallol (142.4 mg/kg extract) were found to be the most abundant ingredients in the WEC. On the other hand, pyrogallol (264.3 mg/kg extract), ferulic acid (224.7 mg/kg extract) and p-coumaric acid (170.2 mg/kg extract) were found as the most plentiful chemicals in the EEC. For the estimation of the antioxidant capacities of the both extracts (WEC and EEC), DPPH center dot and ABTS(center dot+) scavenging activities, as well as Fe3+-Fe2+, and Cu2+-Cu+ reducing assays were studied. The IC50 values of the WEC and EEC indicated that they were potent effective DPPH center dot (21. 25 and 15.71 mu g/mL) and ABTS(center dot+) (6.52 and 5.79 mu g/mL) scavengers, as well as AChE (221.33 and 110.26 mu g/mL), BChE (461.69 and 94.93 mu g/mL), alpha-glycosidase (206.86 and 220.00 mu g/mL) and alpha-amylase (189.86 and 200.86 mu g/mL) inhibitors. As a conclusion, both EEC and WEC had rich phenolic contents and demonstrated effective anticholinergic, antidiabetic and antioxidant effects.

The bioavailability of drugs can be improved by regulating the structural properties, particularly lipoid systems, such as niosomes, can increase cellular uptake. Herein, we optimized double emulsion and niosomal formulations for encapsulating anthocyanin-rich black carrot extract. Nanoparticles obtained by selected formulation were characterized in terms of morphology, particle size, drug encapsulation efficiency, in vitro release and cytotoxicity. The optimum conditions for niosomal formulation were elicited as 30 mg of cholesterol, 150 mg of Tween 20 and feeding time of 1 min at a stirring rate of 900 rpm yielding the lowest average particle size of 130 nm. In vitro release data showed the majority of the encapsulated anthocyanins were released at the end of 10 h. A mathematical model was developed to estimate the absorption of anthocyanins released from niosomes and cytotoxicity was assessed against neuroblastoma. Overall, these findings suggest that niosomal vesicles might be suitable delivery systems for anthocyanins.

Present study aims to investigate the effects of the presence of nano sized TiO2 particles in the base fluid on entropy generation rate in a microchannel heat sink. Pure water was chosen as base fluid, and TiO2 particles were suspended into the pure water in five different particle volume fractions of 0.25%, 0.5%, 1.0%, 1.5% and 2.0%. Under laminar, steady state flow and constant heat flux boundary conditions, thermal, frictional, total entropy generation rates and entropy generation number ratios of nanofluids were experimentally analyzed in microchannel flow for different channel heights of 200 mm, 300 mm, 400 mm and 500 mm. It was observed that frictional and total entropy generation rates increased as thermal entropy generation rate were decreasing with an increase in particle volume fraction. In microchannel flows, thermal entropy generation could be neglected due to its too low rate smaller than 1.10e-07 in total entropy generation. Higher channel heights caused higher thermal entropy generation rates, and increasing channel height yielded an increase from 30% to 52% in thermal entropy generation. When channel height decreased, an increase of 66%-98% in frictional entropy generation was obtained. Adding TiO2 nanoparticles into the base fluid caused thermal entropy generation to decrease about 1.8%-32.4%, frictional entropy generation to increase about 3.3%-21.6%. (C) 2018 The Authors.

İncele - MakaleAçık Erişim2018Automatic extraction of building boundaries from high resolution images with active contour segmentation
Akbulut, Z.; Özdemir, S.; Acar, H.; Dihkan, M.; Karsli, F.
Building extraction from remotely sensed images plays an important role in many applications such as updating geographical information system, change detection, urban planning, disaster management and 3D building modeling. Automatic extraction of buildings from aerial images is not an easy task because of background complexity, lighting conditions and vegetation cover that reduces separability or visibility of buildings. As a result, automatic building extraction can be a complex process for computer vision and image processing techniques. In order to overcome this difficulty region-based active contour model was used to automatically detect the boundary of buildings for this study. To extract object boundaries, the model grows or shrinks the initial contour in the image. The main objective of this paper is making active contours algorithm perform without user interaction and to detect automatically initial contours to segment buildings with a software coded in Matlab. This task carried out by morphological operations, band ratio and thresholding methods. In this study, high resolution aerial images with 8 cm ground sampling distance (GSD) were used. Three separate test zones were selected with varying building level of detail on these images. Finally, it was assessed the accuracy of segmented buildings using Correctness, Completeness and Quality metrics by comparing the results images and manually digitized reference image. The proposed approach for building extraction from images was shown to be 98% accurate on buildings with simple geometry and homogeneous roof textures. However accuracy of extracted buildings with heterogeneous roof textures and lighting, and complex geometry is 89%. The results clearly show that automatically calculated initial contour positions work in accordance with the active contour algorithm and easily extraction of the buildings boundaries.

Güllüpunar, Hasan; Tekmen, Tuba
The perception of a corporation by its environment is based on the presented conducts, produced service or product, and established communication with the target group in this process. This is the result of active communication between the source and the recipient. At the same time, there are marks of the past and the future in this perception. Both the total perception that has developed based on the interaction between the corporation and target groups for different reasons in the past, and the emotion that this interaction creates in relation to the future affect the outlook on the corporate outputs. Therefore, two types of perception can be defined by the environment of an institution. The first is a perception that is defined by the active communication process based on corporate behaviour, product, or service. The second is a perception that is an important factor in the background of the first perception and at the same time it is related to the past and the future which is affected from the first perception. These are defined in the literature as image and reputation. This study inquires into the effect of the citizens' impressions provided by the municipalities in terms of the president, staff or services on the general perception of the municipalities. In this context, a survey was conducted in Giresun city centre regarding Giresun Municipality. In the research, image factors related to municipality services and the power of representatives of Giresun Municipality based on the president and the staff were determined and then the effect of these factors on Giresun Municipality's general perception was examined. In the study, it was concluded that the image factors are important explanations of the general perception of the municipality and the biggest 'factor on the general perception is the mayor 'factor.

Institutional economics literature suggests that inclusive institutions encourage economic growth by increasing efficiency in many sectors of the economy. Institutional structure also has effects on the tourism sector due to the confidential environment and incentives it brings. In this context, when studies on determinants of tourism are examined, it is remarkable that there are a number of studies on economic and social factors, but that there are limited studies about institutional determinants of tourism. This study investigates the causal relationships between institutional factors and tourism sector in nine Mediterranean coastal countries also including Turkey for the period of 1995-2015 by using Konya (2006) panel causality analysis. The results of the study using variables of corruption and democratic accountability as indicative of institutional structure reveal causal relations between tourism expenditures and institutional factors.

This study carried out to determine the combustion properties of the sessile oak wood (Quercus petraea L.) which impregnated with wood preservative and subjected to surface treatments. For this purpose, the samples, which were prepared from sessile oak wood according to ASTM-E 160-50 combustion principles, impregnated with wolmanit-CB (WC) and tanalith-E (T) in accordance with ASTM-D 1413-76 and then synthetic (St) and Water-based (wb) varnishes were applied according to ASTM-D 3023. The combustion test was carried out in 3 stages, combustion with flame (CWF), self-combustion without flame source (CWOF) and ember combustion stage (ECP). It was aimed to determine the combustion temperature values in CWF, CWOF and ECP stage, weight loss, total combustion time and demolition time. As a result, impregnation applications have increased the total combustion time to between 15-18% and reduced the demolition period. The exact opposite results were obtained for the varnish types, the total combustion time was reduced by 19-21% and the demolition time increased by 10-22%. In CWF stage, the highest temperature was obtained in water-based varnished samples (490 degrees C), the lowest in non-varnished samples (458 degrees C); in CWOF stage the highest temperature in water-based varnished samples (572 degrees C), the lowest in synthetic varnished samples (544 degrees C); and in ECP stage the highest temperature in non-varnished samples (306.5 degrees C), the lowest in the samples with the synthetic varnished (262.7 degrees C).

Reis, Catal H.
Photogrammetry has been used for medical diagnostic and treatment. Mostly used medical photogrammetric techniques are Ultrasound, Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) images. CT and MRI are the most effective method for the early detection of foot and ankle anomaly. Researchers have been developing various methods to detect anomaly. Many image segmentation techniques are available in the literature. Computer Aided Diagnosing (CAD) system has been proposed in this study for detection of foot bone anomaly by the analysis of CT images. In this study, a segmentation based on edge detection method is proposed for the classification of anomaly in foot CT images. Edge detection algorithms are the most commonly used techniques in image processing for edge detection. Canny edge detector is evaluated in this study. In this study, .dicom medical image standard format and ten male patient's foot CT images (245 images and 50 test data) are used. The used parameters are detector collimation of 64 mm, scanning thickness of 1-5 mm, and pixel sizes of 512x512 in radiometric resolution of 16 bits' gray levels. The proposed method consists of five major steps: (i) calculating the horizontal & vertical gradient, (ii) determining gradient magnitude and gradient direction, (iii) applying non-maximal suppression, (iv) computing high and low thresholds, (v) hysteresis thresholding are applied to the multi-detector computed tomography to detect the bone anomaly. In this study, automatic edge-based digital image processing techniques are applied to detect of foot bone anomaly. The proposed canny segmentation method enables users segment anomaly in MDCT of foot very quickly and efficiently. The results demonstrate that the proposed segmentation method is effective for segmenting anomaly. The proposed method obtains satisfactory performances in terms of accuracy and F-measure the area under Receiver Operating Characteristic curve (ROC curve (AUC)). The proposed segmentation method achieves an accuracy of 0.86 and F-measure of 0.92, respectively. The purpose of our study is to detect the anomaly of the foot and it was the simplest and less time consuming process.

Öztürk, Serkan; Ghassemi, Mohammad Reza; Sari, Mahmut
In this study, we aimed to derive the new and more reliable empirical relationships among different seismic parameters associated with the earthquake rupture mechanisms for Iranian earthquakes. For this purpose, we firstly converted the surface wave magnitudes into moment magnitudes in order to prepare a uniform earthquake dataset. Thereafter, we estimated the empirical relationships between moment magnitude and surface rupture length, moment magnitude and maximum displacement, and surface rupture length and maximum displacement. These linear empirical equations were obtained by orthogonal regression and the goodness of fits were discussed in terms of the correlation coefficients. The results obtained by the orthogonal regression in this paper are compared with the results obtained by the least square method in the literature. The present study confirms that representations of statistical correlations among different earthquake faulting parameters can be given more clear and straightforward by the orthogonal regression as compared to the least square method. In addition, such kind of relationships may provide some significant insights for the calculation of the maximum surface rupture length, maximum surface displacement, and associated maximum credible earthquakes for different seismotectonic regions of Iran as well as the estimation of earthquake magnitudes in paleoseismological studies.

Çullu, Mustafa
The purpose of this study is to investigate the physical and mechanical properties of concrete produced from lead-zinc mine waste (tallow) products. In this context, the physical chemical, mineralogical and petrography characteristics of rocks obtained from zinc-lead mine were analyzed first. Concrete strength classes of C16/20, C25/30 and C35/45 5 replaced with 25%, 50% and 75% rates of limestone were prepared with lead mine waste. The physical and mechanical properties of the prepared concrete samples were determined. As a result, when lead-zinc mine waste is used as concrete aggregate, while the porosity and the water absorption of prepared samples were decreased, the physical density were increased as compared to limestone. As the result of the positive effect of physical properties, compressive and tensile strength were increased.

Gökçür, Uyesi Engin
Suffixes -(I)p and -(U)p have been used as verbal adverb suffixes during the historical development of Turkish language. When these suffixes are added, verbs modify the central meaning in terms of 'situation, time and style.' Therefore, they are used instead of the verbal adverb suffix (- arak), not used in Turkmen Turkish, that is used to refer to situation and style. These suffixes mostly form verbal adverbs stating situation and style with their function mentioned above in Turkmen Turkish. Besides, when they are added to verbs, they form descriptive verbs by attaching verbs to auxiliary verbs. In this case, it has been seen that they take role in the formation of descriptive verbs that refer to sufficiency, quickness, duration, process, ending and starting. As these suffixes have the function of attaching completed conclusions to another conclusion, they have lost their verbal adverb function in time in Azerbaijani Turkish as in Turkmen Turkish and have been used as past perfect tense. These suffixes are used especially in second-person singular and plural in past perfect form in Turkmen Turkish. They are used in the form of past perfect tense when followed by the (- dir) affix.
