class="card-text"><strong>Abstract:</strong></p> <p>This paper presents a quantitative analysis on the need for automotive calibration methods for digital tachographs. Digital tachographs are mandatory for vehicles used in people and goods transport and they are an important aspect for road safety and inspection. Digital tachographs need to be calibrated for workshops in order for the digital tachograph to display and record speed and odometer values correctly. Calibration of digital tachographs can be performed either manual or automatic. It is shown in this paper that manual calibration of digital tachographs is prone to errors and there can be differences between manual and automatic calibration parameters. Therefore automatic calibration methods are imperative for digital tachograph calibration. The presented experimental results and error analysis clearly support the claims of the paper by evaluating and statistically comparing manual and automatic calibration methods.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Digital%20tachograph" title="Digital tachograph">Digital tachograph</a>, <a href="https://publications.waset.org/search?q=road%20safety" title=" road safety"> road safety</a>, <a href="https://publications.waset.org/search?q=tachograph%20calibration" title=" tachograph calibration"> tachograph calibration</a>, <a href="https://publications.waset.org/search?q=tachograph%20workshops." title=" tachograph workshops.

For this purpose, an experimental program was conducted with four different SCs of 1.85, 3.0, 4.15, and 5.30%, three different WT of 0 (just after production), 15, and 30 minutes and three different CT of 18, 30, and 40 &deg;C. Solid precursors are activated by water glass and sodium hydroxide solutions with silicate modulus (Ms = SiO<sub>2</sub>/Na<sub>2</sub>O) of 1. Slag content and (water + activator solution)/slag ratio were kept constant in all mixtures. Yield stress and plastic viscosity values were defined for each mixture by using the ICAR rheometer. Test results were demonstrated that all of the three studied parameters have tremendous effect on the yield stress and plastic viscosity values of the alkali activated slag concretes. Increasing the SC, WT, and CT drastically augmented the rheological parameters. At the 15 and 30 minutes WT after production, most of the alkali activated slag concretes were set instantaneously, and rheological measurements were not performed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Alkali%20activation" title="Alkali activation">Alkali activation</a>, <a href="https://publications.waset.org/search?q=slag" title=" slag"> slag</a>, <a href="https://publications.waset.org/search?q=rheology" title=" rheology"> rheology</a>, <a href="https://publications.waset.org/search?q=yield%20stress" title=" yield stress"> yield stress</a>, <a href="https://publications.waset.org/search?q=plastic%20viscosity." title=" plastic viscosity.

Social media offers individuals and groups with an opportunity for participatory socialization over the internet, which is free of any time and place restrictions. Social media is a kind of interactive communication and bilateral social network. Various communication contents can be shared and put into mass circulation easily and quickly through social media. These sharings are not only limited to individuals but also happen to groups, institutions, and different constitutions. Their contents consist of any type of written message, audio and video files. We are living in the social media era now. It is not surprising that social media which has extensive communication facilities and massive prevalence is used in politics. Therefore, the use of social media (Facebook) by political parties during the Turkish general elections held on June 7, 2015, has been chosen as our research subject. Four parties namely, AKP, CHP, MHP and HDP who have the majority of votes in Turkey and participate in elections in Konya have been selected for our study. Their provincial centers&rsquo; and parliamentary candidates` use of social media (Facebook) on the last three days prior to the election have been examined and subjected to a qualitative analysis by means of content analysis.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Social%20media" title="Social media">Social media</a>, <a href="https://publications.waset.org/search?q=June%207%20general%20elections" title=" June 7 general elections"> June 7 general elections</a>, <a href="https://publications.waset.org/search?q=politics" title=" politics"> politics</a>, <a href="https://publications.waset.org/search?q=Facebook." title=" Facebook.

Military interventions are commonly called coup in the society. By coup we mean that the armed forces seize political power either by a group of officer in the army or by chain of command. Coups not only weaken but also suspend the democracy in a country. All periods of coup created its own victims. Two military coups which took place in May 27, 1960 and September 12, 1980 are the most important ones in terms of political and social effect in the Turkish Political History. Apart these, March 12, 1971, February 28, 1997 and April 27, 2007 e-memorandum are the periods when Army submitted a memorandum and intervened the political government indirectly. Beside the memorandums and coups there were also many coup attempts that have been experienced in the Turkish Political History. In this study, we examined the coup attempted by FETO&rsquo;s military members in the evening of July 15, 2016 from the point of the Turkish Press.

Accurate evaluation of obesity in children requires difficult and detailed investigation. In our study, obesity in children was evaluated using new body fat ratios and indices. Assessment of anthropometric measurements, as well as some ratios, is important because of the evaluation of gender differences particularly during the late periods of obesity. A total of 239 children; 168 morbid obese (MO) (81 girls and 87 boys) and 71 normal weight (NW) (40 girls and 31 boys) children, participated in the study. Informed consent forms signed by the parents were obtained. Ethics Committee approved the study protocol. Mean ages (years)&plusmn;SD calculated for MO group were 10.8&plusmn;2.9 years in girls and 10.1&plusmn;2.4 years in boys. The corresponding values for NW group were 9.0&plusmn;2.0 years in girls and 9.2&plusmn;2.1 years in boys. Mean body mass index (BMI)&plusmn;SD values for MO group were 29.1&plusmn;5.4 kg/m<sup>2</sup> and 27.2&plusmn;3.9 kg/m<sup>2 </sup>in girls and boys, respectively. These values for NW group were calculated as 15.5&plusmn;1.0 kg/m<sup>2</sup> in girls and 15.9&plusmn;1.1 kg/m<sup>2 </sup>in boys. Groups were constituted based upon BMI percentiles for age-and-sex values recommended by WHO. Children with percentiles &gt;99 were grouped as MO and children with percentiles between 85 and 15 were considered NW. The anthropometric measurements were recorded and evaluated along with the new ratios such as trunk-to-appendicular fat ratio, as well as indices such as Index-I and Index-II. The body fat percent values were obtained by bio-electrical impedance analysis. Data were entered into a database for analysis using SPSS/PASW 18 Statistics for Windows statistical software. Increased waist-to-hip circumference (C) ratios, decreased head-to-neck C, height &lsquo;to&rsquo; &lsquo;two&rsquo;-&lsquo;to&rsquo;-waist C and height &lsquo;to&rsquo; &lsquo;two&rsquo;-&lsquo;to&rsquo;-hip C ratios were observed in parallel with the development of obesity (p&le;0.001). Reference value for height &lsquo;to&rsquo; &lsquo;two&rsquo;-&lsquo;to&rsquo;-hip ratio was detected as approximately 1.0. Index-II, based upon total body fat mass, showed much more significant differences between the groups than Index-I based upon weight. There was not any difference between trunk-to-appendicular fat ratios of NW girls and NW boys (p&ge;0.05). However, significantly increased values for MO girls in comparison with MO boys were observed (p&le;0.05). This parameter showed no difference between NW and MO states in boys (p&ge;0.05). However, statistically significant increase was noted in MO girls compared to their NW states (p&le;0.001). Trunk-to-appendicular fat ratio was the only fat-based parameter, which showed gender difference between NW and MO groups. This study has revealed that body ratios and formula based upon body fat tissue are more valuable parameters than those based on weight and height values for the evaluation of morbid obesity in children.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Anthropometry" title="Anthropometry">Anthropometry</a>, <a href="https://publications.waset.org/search?q=childhood%20obesity" title=" childhood obesity"> childhood obesity</a>, <a href="https://publications.waset.org/search?q=gender" title=" gender"> gender</a>, <a href="https://publications.waset.org/search?q=Morbid%20obesity." title=" Morbid obesity."> Morbid obesity.</a> </p> <a href="https://publications.waset.org/10005668/gender-differences-in-morbid-obese-children-clinical-significance-of-two-diagnostic-obesity-notation-model-assessment-indices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10005668/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10005668/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10005668/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10005668/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10005668/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10005668/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10005668/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10005668/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10005668/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10005668/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10005668.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">958</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Laboratory Indices in Late Childhood Obesity: The Importance of DONMA Indices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Orkide%20Donma">Orkide Donma</a>, <a href="https://publications.waset.org/search?q=Mustafa%20M.%20Donma"> Mustafa M.

Especially morbid obesity is an important problem for the children because of the associated diseases such as diabetes mellitus, cancer and cardiovascular diseases. In this study, body mass index (BMI), body fat ratios, anthropometric measurements and ratios were evaluated together with different laboratory indices upon evaluation of obesity in morbidly obese (MO) children. Children with nutritional problems participated in the study. Written informed consent was obtained from the parents. Study protocol was approved by the Ethics Committee. Sixty-two MO girls aged 129.5&plusmn;35.8 months and 75 MO boys aged 120.1&plusmn;26.6 months were included into the scope of the study. WHO-BMI percentiles for age-and-sex were used to assess the children with those higher than 99<sup>th</sup> as morbid obesity. Anthropometric measurements of the children were recorded after their physical examination. Bio-electrical impedance analysis was performed to measure fat distribution. Anthropometric ratios, body fat ratios, Index-I and Index-II as well as insulin sensitivity indices (ISIs) were calculated. Girls as well as boys were binary grouped according to homeostasis model assessment-insulin resistance (HOMA-IR) index of &lt;2.5 and &gt;2.5, fasting glucose to insulin ratio (FGIR) of &lt;6 and &gt;6 and quantitative insulin sensitivity check index (QUICKI) of &lt;0.33 and &gt;0.33 as the frequently used cut-off points. They were evaluated based upon their BMIs, arms, legs, trunk, whole body fat percentages, body fat ratios such as fat mass index (FMI), trunk-to-appendicular fat ratio (TAFR), whole body fat ratio (WBFR), anthropometric measures and ratios [waist-to-hip, head-to-neck, thigh-to-arm, thigh-to-ankle, height/2-to-waist, height/2-to-hip circumference (C)]. SPSS/PASW 18 program was used for statistical analyses. p&le;0.05 was accepted as statistically significance level. All of the fat percentages showed differences between below and above the specified cut-off points in girls when evaluated with HOMA-IR and QUICKI. Differences were observed only in arms fat percent for HOMA-IR and legs fat percent for QUICKI in boys (p&le; 0.05). FGIR was unable to detect any differences for the fat percentages of boys. Head-to-neck C was the only anthropometric ratio recommended to be used for all ISIs (p&le;0.001 for both girls and boys in HOMA-IR, p&le;0.001 for girls and p&le;0.05 for boys in FGIR and QUICKI). Indices which are recommended for use in both genders were Index-I, Index-II, HOMA/BMI and log HOMA (p&le;0.001). FMI was also a valuable index when evaluated with HOMA-IR and QUICKI (p&le;0.001). The important point was the detection of the severe significance for HOMA/BMI and log HOMA while they were evaluated also with the other indices, FGIR and QUICKI (p&le;0.001). These parameters along with Index-I were unique at this level of significance for all children. In conclusion, well-accepted ratios or indices may not be valid for the evaluation of both genders. This study has emphasized the limiting properties for boys. This is particularly important for the selection process of some ratios and/or indices during the clinical studies. Gender difference should be taken into consideration for the evaluation of the ratios or indices, which will be recommended to be used particularly within the scope of obesity studies. <p
