311+G(2d,p) level of theories.
A SHOT IN THE ARM FOR HANDLING CONSUMER DISPUTES ACROSS THE EU: ALTERNATIVE DISPUTE RESOLUTION SYSTEM Yildiz Sekban
Abstract:
The handling of disputes between consumers and traders is now evolving on a more
consumer-friendly ground across Europe. Following the steadily stronger consumer protection
laws, the growth of online mechanisms for alternative dispute resolution (ADR) bodies is further
swinging the legal pendulum from the judicial protection to developing out-of-court structures that
provide cheaper and effective relief. In this regard, the recent launch of a new online dispute
resolution (ODR) platform by the European Commission is quite likely to contribute to the effort
to avoid disputes reaching court, providing settlement of the millions of both domestic and crossborder
e-commerce disputes using online technologies, as well as strengthening the EU’s Digital
Single Market Strategy. The disputes will be channelled to national ADR bodies in each Member
State that are related to the platform of which online traders are required to provide notice.
AN ANALYTIC VELOCITY AND ACCELERATION ANALYSIS OF A PLANAR PARALLEL 3-RRR MECHANISM Engin CAN
Abstract:
This paper focusses on the velocity and acceleration analysis of a planar
parallel kinematic chain by an analytic method. The velocity analysis reveals that there
are poses with either no pole configuration or an infinite number of pole configurations.
These poses are called singular or twice singular, respectively. It turns out that in general
the singular poses are those where the cranks need to reverse the rotation in order to
perform the full motion. At twice-singular poses, bifurcations can take place. The analytic
method reduces the local velocity and acceleration analysis to systems of linear equations.
Their rules for solvability confirm again the results on singular and twice singular poses.
Both can be geometrically characterized by the concurrency of triples of lines. The
analytic and algorithmic treatment of the global constrained motion leads to an algebraic
problem of degree 6.
ANTI-SCALE MAGNETIC METHOD AS A PREVENTION METHOD FOR CALCIUM CARBONATE SCALING M. A. Salman, G. Al-Nuwaibit
Abstract:
The effect of anti-scale magnetic method (AMM) in retarding scaling deposition is
confirmed by many researchers, to result in new crystal morphology, crystal which has the
tendency to remain suspended more than precipitated. AMM is considered as an economic
method when compared to other common methods used for scale prevention in desalination plant
as acid treatment and addition of antiscalant. The current project was initiated to evaluate the
effectiveness of AMM in preventing calcium carbonate scaling. The AMM was tested at different
flow velocities (1.0, 0.5, 0.3, 0.1, and 0.003 m/s), different operating temperatures (50, 70, and
90°C), different feed pH and different magnetic field strength. The results showed that AMM
was effective in retarding calcium carbonate scaling deposition, and the performance of AMM
depends strongly on the flow velocity. The scaling retention time was found to be affected by the
operating temperatures, flow velocity, and magnetic strength (MS), and in general, it was found
that as the operating temperatures increased the effectiveness of the AMM in retarding calcium
carbonate (CaCO3) scaling increased.

EFFECT OF Al CONTENT ON STRUCTURE AND WEAR BEHAVIOR OF AlCoCrFeMoNi HIGH ENTROPY ALLOYS Hakan GAŞAN, Ersu LÖKÇÜ
Abstract:
High-entropy AlxCoCrFeMo0.5Ni (x=0-2) alloys are prepared by the vacuum arc
melting and casting method. The effects of Al content on the microstructure, hardness and wear
resistance of the high-entropy alloys (HEAs) are investigated. The HEAs were characterized
for phase content by X-ray diffractometer (XRD) and morphology by scanning electron
microscope (SEM). Wear tests were performed under dry friction conditions with WC balls at
a 5 N normal load and sliding speed of 5 cm·s-1 in a ball-on-disc geometry. The worn surfaces
of the samples were also examined by SEM to identify the wear mechanism. The hardness starts
from 328 HV, at x=0, reach to the maximum, 710 HV, at x=1.0 and then declines to 684 HV,
at x=2.0. On the other hand, the wear resistance of HEAs gradually increases with the increasing
aluminum content. The correlation between composition, microstructure, hardness and wear
properties of these alloys is detailed discussed with in this study.
EFFECTS OF CHEMICAL MODIFICATION ON WOOD PROPERTIES Suat ALTUN
Abstract:
Chemical modification can be used to improve the properties of wood. Effect of
melamine formaldehyde modification on the physical and mechanical properties of Scots pine and
Chestnut was investigated in this study. Wood samples were impregnated with melamine
formaldehyde (MF) resin under 3 bar pressure for 10 or 30 min and were cured at a temperature of
150 °C for 20 min in an oven. Weight percent gain, water uptake, volumetric swelling, Brinell
hardness, modulus of rupture and modulus of elasticity values of the samples were determined
according to relevant standards. Modification with MF reduced the water uptake and the volumetric
swelling of the woods. Anti-swelling efficiency of the modification were approximately 66 % and
57 % in chestnut and scots pine, respectively. MOE increased in scots pine (3% - 17 %) while
unchanged in chestnut but MOR decreased significantly by modification in both chestnut (2.5% -
17.9%) and scots pine (26.2% - 32.7%). Also, MF modification increased the Brinell hardness of
the wood, slightly.
EVALUATION OF ARASTAS AND BAZAARS OF OTTOMAN CITIES WITHIN THE CONTEXT OF CONSTRUCTION MATERIALS AND ARCHITECTURAL TYPOLOGIES Özlem ATALAN, Hasan Şahan AREL
Abstract:
In Anatolian cities of the Ottoman period, such as the inns, bedestens (covered bazaars),
arastas, bazaars, grand bazaars and stores formed the commercial centers. These commercial
structures with different functions were the main components forming the fabric of the commercial
districts. These commercial centers also contained major public buildings, such as mosques and
baths. Depending on the size of a city or town, the number of these structures could vary greatly.
All of the buildings located in the center were important facilities, contributing economic, social
and distinctive features to an Anatolian city or town. In this study, the “Arasta” and “Bazaar” in
historical cities located on the axes of important trade routes in Anatolia were investigated. In
addition, the conceptual and architectural differences of arastas and bazaars from inns and
bedestens, which are major commercial structures, were investigated. The structures were selected
from the cities of Ä°stanbul, Bursa, Edirne, Hatay, and Konya, which were located on the important
trade routes of the time. Especially, construction and material techniques, plan and façade
typologies of these structures, built in the 15th and 16th centuries, were evaluated, as were the
common and distinctive features of the various cities.

Abstract:
This paper is a report on the findings of a study conducted on a graduate level virtual
conference summer school course. Discourse analysis techniques were used to examine the
resulting transcript of texts for evidence of a democratic discourse within a community of learners.
Findings indicate that gender is not masked in the text driven discussions on the Internet.
Distinctive discursive styles are often sex class linked. Like face to face or classroom contexts,
status is accorded unequally within discourse communities. Participants are not equal and are not
equally attended or responded to. Educators need to take a serious and wary approach to accepting
claims of ensured democratic participation in computer mediated communication formatted classes.
HEAVY METAL REMOVAL BY POLYMER – ZEOLITE BASED ADSORBENT Hasan Emre ASLAN, Barış ŞEKER, Çiğdem KIVILCIMDAN MORAL
Abstract:
Water resources are threatened by a lot of pollutants such as heavy metals. Copper,
a heavy metal, is quite toxic at high concentrations similar to the other heavy metals. These
metals can also accumulate fatty tissues of livings. Due to these reasons heavy metals should
be removed from wastewaters before being discharged. There are many methods to remove
heavy metals such as chemical precipitation, ion exchange, membrane technologies, etc.
Adsorption is an alternative method which is cheap, easy to apply and effective. Various
adsorbents including biopolymers are used efficiently for heavy metal removal. Alginate is one
of them composed of mannuronic and guluronic acid monomers. Alginate can form beads by
adding mostly calcium which were used for heavy metal removal. Recent studies were
particularly focused on improvement of these beads by adding some materials capable of
capturing heavy metals such as clay, bentonite, activated carbon, etc. In this study, a natural
zeolite, clinoptilolite was used to increase copper removal capacity of alginate beads. For
copper removal, series of adsorption experiments were performed under constant temperature
and mixing rate. Alginate-clinoptilolite beads were found to be more effective (almost 20 % of
higher copper removal) compared to alginate beads alone. Adsorption of copper was
equilibrated after about 8 hours of incubation and the highest copper reduction was observed as
87 mg Cu2+/g alginate-clinoptilolite beads at initial Cu2+ concentration of 100 mg/L.
INFLUENCE OF MICA CONTENT ON DYNAMIC SHEAR MODULUS OF SANDY SOILS Seda DURUKAN , Ender BAÅžARI
Abstract:
The Gediz River Delta soils contain abundant flatty (platy) mica grains. Mica grains can
alter static and dynamic engineering characteristics of sandy soils due to their flatty shapes. In this
study, influence of mica grains on dynamic shear modulus of sandy soils in Gediz River Delta was
investigated. Maximum shear modulus (Gmax), which is a major parameter in dynamic soil response
analyses, can be obtained at small deformation amplitudes. Therefore, it is determined through
measurement of shear wave velocity. Shear wave velocity provide valuable information about
dynamic characteristics of soils. So it is very important to determine the shear wave velocity with
high accuracy for dynamic soil response analysis. In this respect, firstly engineering boreholes were
drilled and sandy soil samples were recovered along the borehole depth. The mica content of the
samples was determined by means of X-RD analysis method. Then test sample contain 1.5%, 10%
20% mica grains were prepared to represent the Gediz River soils. Shear wave velocity of the sand
samples were determined with bender element tests under 100 kPa cell pressures in triaxial test
device. Followed by the bender element tests maximum shear modules were determined. End of
the test program, shear wave velocity of the dense (Dr:55%) samples were determined as 249 m/sn,
214 m/sn and 187 m/sn for 1.5%, 10% and 20% mica content respectively. Mica was reduced the
shear wave velocity in considerable percentage about 25% rate. Smiler effect was observed on the
maximum shear modules and it is determined as 111.6 MPa, 82.4 MPa, and 62.9 MPa for 1.5%,
10%, 20% mica contents respectively for dense samples (Dr:55%). 20% mica content was reduced
the shear wave velocity about 44% rate.

LIDAR DATA ANALYSIS WITH DIGITAL IMAGE CORRELATION (DIC) IN OBTAINING LANDSLIDE DISPLACEMENT FIELDS: A CASE OF GSCHLIEFGRABEN LANDSLIDE-AUSTRIA Abdurrahim AYDIN, Remzi EKER, Helmut FUCHS
Abstract:
Comparison of LIDAR datasets were shown as useful in obtaining information about
displacement fields of active landslides. Iterative closest point (ICP) and digital image correlation
(DIC) are two main approaches used for this aim. Whereas ICP is based on precisely matching
point-clouds, DIC is based on cross-correlation of remotely sensed digital imageries. Although DIC
is a popular application in fluid mechanics for quantifying flow velocity, its successful applications
in estimating displacements resulted from landslides are available. Studies indicate that DIC is more
suitable than ICP when computing displacements in the order of magnitude of several meters. DIC
is applied to any raster dataset representing a surface property considering the specific advantages
and disadvantages of these techniques. In the present study, DIC was applied for an active landslide
(named Gschliefgraben) located in Upper Austria. Two time series of LIDAR data obtained in 11th
February 2008 and 28th April 2008 was used. The precision of DEMs with 1*1m raster cell size is
20 cm (horizontal) and 15 cm (vertical). Because Gschliefgraben is a big landslide system, DIC
analysis was only made for small part of landslide area located close to the crown (head). This part
was selected because more activation was observed between two series with visual inspection.
Within the study area two separate active parts were observed. According to results, between two
time series, the mean displacement rates in these more active parts within study area were obtained
0.66 m (max. 2 m) with sub-pixel precision image matching.

Abstract:
In today's competitive world, the success of firms is directly proportional to the extent
to which sustainability is involved in business processes. Therefore, the sustainability
performance evaluations of the firms have become a very important issue. In this study, it has
been aimed to evaluate the corporate sustainability performance by using MCDM (Multi-Criteria
Decision Making) methods. In this respect, the corporate sustainability performance of the firm
Brisa, which operates in the international rubber and coating sector, has been evaluated on the
basis of economic, environmental and social aspects. In the study on which the period of 2011-
2015 has been taken as basis, the data needed has been obtained from the annual reports of the
firm. In the study, only the objective weighting methods such as ENTROPY, CRITIC, SD
(Standart Deviation) and MW (Mean Weight) techniques have been used in order to determine
the relative importance of the criteria, while COPRAS and VIKOR methods have been used for
the performance sequence on a yearly basis. An integrated single sequence has been obtained by
combining the sequences obtained with the BORDA COUNT method, a data combining
technique. As a result of the analysis, it has been concluded that the approach suggested in the
study was an effective and appropriate approach that could be used in assessing the corporate
sustainability performance.
PHENOLIC COMPOUNDS IN POMEGRANATE VINEGARS Serkan SELLÄ°
Abstract:
Pomegranates are widely researched fruits for their nutritional and health benefits as well
as their organoleptic properties. Pomegranate juices are rich in vitamins, minerals and
phytochemicals. In addition, pomegranate juices contain potentially bioactive compounds and they
are a great source of phenolic compounds such as flavonoids and phenolic acids. The use of second
quality pomegranate for vinegar production can be a proper method to reduce losses due to discard
of fruits. There has been growing interest in the beneficial health effects of certain fruits, wines and
their by-products, like vinegars. In this study, the main phenolic compounds of pomegranate
vinegars were determined by HPLC–DAD–ESI-MS. Diode-array detection (DAD) has been used
for screening of the different classes of phenolic compounds, whereas MS and MSn fragmentation
data were employed for their structural characterization. Most of the compounds detected were
mainly anthocyanins such as delphinidin, cyanidine and pelargonidine, and ellagitannins such as
ellagic acid, punicalagin and punicaline. Additionally, phenolic acids were detected. Antioxidant
activities of pomegranate vinegars were measured by using the DPPH (2,2-diphenyl-1-picryl
hydrazyl) and ABTS (2,2′-azino-bis-3-ethyl-benzothiazoline-6-sulphonic acid) assays. The results
showed strong correlations between antioxidative capacities and total phenolic content of
pomegranate vinegars.

SYNTHESIS, IN VITRO INHIBITION EFFECT AND STRUCTUREACTIVITY RELATIONSHIP OF NEW THYMOL DERIVATIVES ON CHOLINESTERASES Fatih SONMEZ
Abstract:
Alzheimer’s disease (AD) is a progressive neurodegenerative disease and the most
common form of dementia that affects aged people. Acetylcholinesterase is a hydrolase involved
in the termination of impulse transmission at cholinergic synapses by rapid hydrolysis of the
neurotransmitter ACh in the central and peripheral nervous system. Thymol is a main bioactive
monoterpene isolated from many medicinal herbs, such as Thymus vulgaris, Monarda punctate and
Origanum vulgare spp. Thymol has been widely used as an active anti-inflammatory ingredient,
which can inhibit the isoproterenol induced inflammation in myocardial infarcted rats. Moreover,
many studies have reported that thymol has various bioactivities, such as anticancer, anti-bacterial,
and antioxidant properties. In this paper, a series of 12 novel thymol substituted carbamate
derivatives (2a-l) was synthesized and their inhibitory activities on AChE and BuChE
were evaluated. Among them, 2k exhibited the strongest inhibition against AChE with an
IC50 value of 2.498 μM, which was 183-fold more than that of thymol (IC50 = 458.23
μM). The structure-activity relationship were also investigated.
TACTILE SENSOR DESIGN FOR LUMP DETECTION IN BREAST TISSUE Mustafa Zahid Yıldız, Hamid Asadi Dereshgi, Ali Furkan Kamanlı
Abstract:
The purpose of this study is the development of a novel system for detection of breast
tumors in non-invasive way that can be used by doctors or patients. Our study consist of two parts.
The first part is a specialized sensor containing an inductive sensor inside of a tissue-like silicon
rubber robotic fingertip and a square shaped multi-metal-array to increase sensitivity. The whole
system designed as a probe which has compact design and mobility. The system provides 16-bit
resonance impedance and 24-bit inductance values, enabling sub-micron resolution for positionsensing
in application. The tissue-like silicon properties were simulated and the linearity of the
probe design against the pressure was analyzed. Tissue-like silicon rubber has hyper-elastic
specifications. Force-displacement analysis showed %100 linear behavior. Tissue-like rubber
silicon has also elastomer properties. The stress-strain analysis was made for 8 different point that
showed non-linear behavior. With the current probe design, our detecting system is easy to use for
every patients and health clinicians due to its mobility and easy access for different clinical
environment. For the second part, to measure our system performance’s sensitivity and specificity,
comparison simulations will be performed.
In the simulation experiments, tumor-like inclusions embedded in tissue-like cylindrical silicon
samples to make Phantom tissue in Virtual environments (VEs) will be designed. In VEs, the tumorlike
tissue samples will be used in a various combination of stiffness and depth in phantom tissues.
In real phantom experiments, the simulated phantoms will be created by the same silicon-rubber in
similar conditions. The system will be embedded with the camera for tracking the every movement
of robotic fingertip. The camera will record every location information (x,y) and combine it with
the relative stiffness value which is taken from the sensor. And the topographical information of
the tissue-like phantoms turned in to 2-D image. Breast examination can be done by human hands
which have unique mechanism to sense vibrations called Pacinian corpuscle (response 60-700 Hz)
and these sensory systems can be measured around the 200 Hz. In clinics, even though the clinical
procedures are performed by the experts, it’s difficult to detect small tumors and quantify the shape,
location and stiffness. Because of these difficulties, tactile imaging sensors need to be used for
diagnosis. As a future study, human palpation performance will be compared by our novel tactile
sensor design embedded on a robotic fingertip.
TAX INCENTIVES FOR INNOVATION IN THE LIGHT OF IT GOVERNANCE BEST PRACTICES (EVIDENCE FROM THE FINANCIAL SERVICES INDUSTRY AND IMPLICATIONS FOR EXECUTIVES) Hülya BULUT
Abstract:
IT governance frameworks and in particular COBIT, are today accepted
internationally. Particularly in the emerging market of Turkey, there have been efforts to
encourage the use of IT governance but practitioners have had varying perspectives. IT
governance allows businesses, for example, those in the financial service markets, to align
themselves with strategies in the information technology sector. Many companies adopt IT
governance to increase efficiency, increase IT infrastructure control, reduce costs, make better
decisions and motivate employees (Lahti and Peterson, 2007). Companies with integrated IT
governance are in a stronger position to increase their organizational accountability, offering
better returns on investment.
Innovation serves the same purpose as IT governance, (managing innovation is a part of
COBIT) fostering competition, productivity and job creation – essential factors for sustainable
growth. Innovation extends beyond mere technological advancement, encompassing new
business models and organizational change. Innovation is frequently a product of R&D
efforts, driven by vectors like IP and software, alongside organizational and human capital.
R&D carries risks both in uncertainty of investment outcomes and spillover effects to third
parties; this risk typically results in below-socially-optimal R&D investment. Governments
frequently intervene to increase R&D investment, either through direct sponsorship of
research or through policy measures, e.g. tax breaks to correct the market failure (OECD,
2013).

a bigger effect on job involvement than friendship opportunity. Theoretical and applied
implications are discussed.
THE INTERACTIVE LEARNING OF INTEGRATING ANIMATION GAME WITH KINECT SYSTEM FOR SENIOR WITH MILD ALZHEIMER Hui-Ying Chang , Shi-Jer Lou, Tsai-Feng Cheng
Abstract:
Alzheimer's disease is one of the common problems for the elders. Some mild symptoms
of the Alzheimer's might be misinterpreted as normal circumstances because of aging, leading to
the procrastination of treatment process. Affected people would have a hard time managing
activities of daily living and forget roads back home, which may jeopardize their live safety.
Because the patients barely leave their homes, it may place significant burdens for patients
themselves and caregivers.
This interactive game of this projects focuses on Flash, with the help of Kinect motion sensor of
Microsoft, making a combination of software and hardware. The skeletal tracking feature of Kinect
enables users to control the mouse and other objects through human body, which allows the elders
to play some simple games at home. The researcher also used easy questions to observe whether
the elders have problems of Alzheimer's, and further to facilitate their brain functions.
The interactive memory learning game for the elders – with the application of Kinect, was
developed in this research. The motion sensor camera of Kinect makes human body become a game
controller, which provides interactions for the memory match game. With the availability of Kinect,
television, and computers, seniors with mild Alzheimer's can facilitate their hand control and limb
movements through simple commands. The memory game could enhance brain stimulation for
seniors with mild Alzheimer's and decelerate aging process, bringing about effects of sport and
entertainment.
THE RELATIONSHIP BETWEEN CHILD AND URBAN SAFETY: CHILD-FRIENDLY SAFE CITIES Tahir Emre GENCER, Damla KARAGÖZ
Abstract:
The main concern of this study is urban areas open to risks despite the child's
need for a safe and healthy environment in the childhood, lack of urban safety in the
streets which are the socialization area and playground of the child and failure to develop
child-friendly urban policies that can solve this safety problem. The aim of the study, on
the other hand, is to identify the lack of safety for children using urban areas full of
dangers during their developmental period, their needs of protection, failure of urban
areas to provide safe environment for children and the shortcomings of child welfare
system in this regard. This study handles current academic publications, current news and
data from the international non-governmental organizations through children's rights and
child-friendly perspective within the scope of literature review.
