Paint Marketing and Factors Affecting the Consumers’ Paint Purchase Preference from the Viewpoint of Paint Industry Members in Turkey

The aim of this research was to examine the consumers' preference of paint purchase from the viewpoint of individuals employed in the Turkish paint industry. It was aimed to reach at least 278 individuals with a sampling error of 5%. Within this scope, 350 questionnaire forms were distributed and 330 were received back in the year of 2017. Since 4 of the returned questionnaires had a missing question, study was conducted with 326 questionnaires. The questionnaire form was used as the data collection tool. It included 5 questions about demographic characteristics, 17 questions concerning purchasing and using behaviors, and 29 questions regarding consumers' preferences of paints. Data analysis of the study was done using the SPSS 16 package program. Through the analysis of data, descriptive statistics such as frequency, percentage, mean and standard error were presented. In addition, t test and ANOVA test were applied to test the relationship among variables. Based on research findings, the most important factors for the preference of paint purchase in Turkey were determined as the aging of existing wall painting, marriage and cleaning issues. Moreover, it was found out that the experiences of consumers were also effective for the paint purchase decision and preference. Within the scope of the study, it was determined that elder individuals, married and high income people were influenced by many factors in their preference for painting. On the other hand; young, single and low-income individuals were considering less factors in their paint preferences. In addition, it was detected that men were considering properties (features) such as the price and quality more than women in their purchasing preferences. Furthermore, the most important factor affecting the purchasing choice of consumers was determined as previous knowledge and experience. It was also found out that consumers did not frequently conduct market research before choosing the paint. Educational status of individuals was not an effective factor concerning paint preferences

Usage Of Underground Space For 3D Cadastre Purposes And Related Problems In Turkey

Modern cities have been trying to meet their needs for space by using not only surface structures but also by considering subsurface space use. It is also anticipated that without planning of underground spaces for supporting surface city life in the years and generations to come, there will be serious and unavoidable problems with growing populations. The current Turkish cadastral system, including land right registrations, has been trying to meet users' needs in all aspects since 1924. Today Turkey's national cadastre services are carried out by the General Directorate of Land Titles and Cadastre (TKGM). The Cadastre Law, Number 3402, was approved in 1985 to eliminate problems by gathering all existing cadastral regulations under one law and also to produce 3D cadastral bases to include underground spaces and determine their legal status in Turkey. Although the mandate for 3D cadastre works is described and explained by the laws, until now the bases have been created in 2D and the reality is that legal gaps and deficiencies presently exist in them. In this study, the usage of underground spaces for the current cadastral system in Turkey was briefly evaluated, the concept of 3D cadastral data is examined and the need for using subsurface and 3D cadastre in addition to the traditional 2D register system, related problems and registration are mentioned with specific examples, but without focusing on a specific model.PubMedWoSScopu

Optimization and validation of ultrasensitive GC-MS/MS method to measure oxidatively induced DNA damage products and role of antioxidants in oxidation mechanism

Oxidation of DNA due to exposure to reactive oxygen species (ROS) is a major source of DNA damage. ROS induced damage to DNA plays an important role in some diseases such as various cancers, aging and neurodegenerative diseases. The detection of DNA oxidation products plays a major role in assessing the mutagenicity potential of specific exposure. The GC-MS/MS method was developed for the ultrasensitive determination of individual DNA damage products. The validation results revealed that the proposed method was reliable and sensitive. Multiple response surface methodology (MRSM) was used to optimize derivatization conditions of oxidatively DNA base damage products before GC-MS/MS analysis. The optimum derivatization conditions were determined as 40 min for derivatization time, 120 degrees C for derivatization temperature and 1.4 for BSTFA/pyridine ratio under nitrogen atmosphere. The effects of thymol, carvacrol and thymoquinone as antioxidants were investigated on oxidative DNA damage. The determination of the oxidatively induced DNA damage products was performed after adding DNA and antioxidants with different concentrations under oxidative stress. Eighteen DNA base damage products were analyzed simultaneously using GC-MS/MS. This study showed a significant decrease in the amount of DNA base damage products when the antioxidants were present in the medium

Effects of different drying conditions on physical changes of apple (Malus communis L.)

Aims: The aim of this study was to investigate some physical changes of apple dried in cabin type dryer and to determine optimum drying conditions. Methods and Results: The volume, diameter, area, width, and thickness properties of fresh fruits and dried fruits were measured using a digital caliper as three replications. Color of products was measured according to CIE-L*, a*, and b* color space, and was calculated color index (CI), hue angle (h*), and chroma (C*) values. According to the findings, optimum drying condition was achieved in cabinet type dryer with the drying parameters of 7 mm 10 hours 50°C and 7 mm 10 hours 60°C. In addition, the highest chroma values after drying were obtained with the drying parameters of 5 mm 9 hours 50°C. Conclusions: In the study, a positive correlation (p=0.99) was found between initial L* and initial area, initial chroma and initial b*, final a* and final b*. Significance and Impact of the Study: Drying is the mass transfer process consisting of the removal of water from the product in order to extend the storage period of the agricultural product and to create a new product market. Drying stages of agricultural products consist of a warming phase, drying stage with constant speed and drying stage with decreasing speed. Due to the loss of moisture during the drying process, some physical changes occur in the products. The optimum drying duration, drying temperature and product thickness should be determined in order to achieve the desired moisture level of the dried product in different drying conditions.</p

Influence of deposition conditions on nanostructured InSe thin films

WOS: 000490123300017In this study, nanostructured indium selenide (InSe) thin films were deposited on Indium fin oxide (ITO)-coated glass substrate using electrochemical deposition (ECD) from aqueous solution containing In(SO4)(3)center dot H2O and SeO2. The effects of deposition potential ( - 0.70 to -1.35 V), time (30-3600 s), temperature (25-80 degrees C) and pH (2.58 for A samples; 2 for B samples and 1.45 for C samples) on growth of the InSe thin films were examined in terms of their structural, morphological and optical properties. X-ray diffraction (XRD) analysis confirmed that the InSe thin films are in polycrystalline structure. It was found that the values of grain size decreased and the full width half maximum (FWHM) values increased with the increasing deposition potential. According to the absorption measurements, optical properties of the thin films varied with changes in deposition conditions. Based on the atomic force microscopy (AFM) and the scanning electron microscopy (SEM) images, surface morphology of the thin films was influenced by deposition potential and pH of the electrolyte, and non-homogeneous depositions distributed across the entire surface were observed. In addition, Raman spectroscopy, X-ray photoelectron spectroscopy (XPS) and fourier transform infrared spectroscopy (FT-IR) analyses were used to further examine crystal quality, vibration, chemical binding conditions, In/Se orientation and structure of the prepared InSe thin films. When Raman results are examined, the B12 sample shows a more intensity and narrow peak at 248 cm(-1). XPS measurements sowed that A6 sample exhibited more growth in low potential for a long time and better film stoichiometry compared to the other three samples. Also, FT-IR studies prove the presence of InSe. According to the results, the film did not form at low temperatures and short times. However, the film formation began with the increasing deposition temperature and time at the low potential value of - 0.730 V. But, it is clear that a high quality film can be obtained in cathodic potential with -1.3 V and shorter deposition time with 300 s at room temperature respectively. Overall results showed that the high quality thin films can be obtained by the ECD technique. However, deposition conditions must be sensitively adjusted to control morphology of the electrodeposited nanoparticles.Ataturk University through Ataturk University Scientific Research Project Council [2016/212]The authors would like to thank Ataturk University for financial support through Ataturk University Scientific Research Project Council (Project No: 2016/212
