This research aims to identify sensors. This research was carried out through 3 stages, namely: designing resistance sensors, making resistance sensors, testing resistance sensors. The sensor sheceme by using software Fritzing. The tools used in making these sensors include Power and solder, for materials used are plain PCB, 2.2KΩ resistors, copper wire, paper, pens, rulers, and materials for testing are tea, natural sugar and artificial sugar. Sensor testing is performed in data collection by measuring voltage. Because the data generated is in the form of voltage. By doing 2 variations of the volume of 50ml and 100ml which is done 5 times with each volume repetition. The data obtained is then processed by calculating the mean and its uncertainty. The results of this research provide information that the natural sugar tea voltage for 50ml volume (0.958 ± 0.1916) 80% repeatability. And for 100ml volume (0.884 ± 0.1768) the compatibility is 80%. While the artificial sugar tea voltage for 50ml volume (1.488 ± 0.2976) 80% compatibility and for 100ml volume (1.484 ± 0.2968) 80% repeability. From the data obtained, both can be seen to have different voltage values and the same compatibility value, which is 80%. Because the resulting repeatability does not reach national standards, this sensor cannot be used.

Materials Used

An acidified dialyzed gelatin gel system was used to determine the caries resistance of a variety of restorative materials used to obturate the canal orifice of overdenture abutment teeth. The restorative materials used were Tytin, Tytin + Copalite, P30 + Scotchbond, Fuji Ionomer-Type II, and Miracle Mix. Polarized light microscopy and microradiography were used to examine the caries-like lesions adjacent to the restorations. The lesions formed in the Fuji Ionomer-Type II and Miracle Mix groups appeared arrested at the wall adjacent to the restoration, and did not penetrate apically down the wall as did those associated with the other restorative materials. The mean depths of lesions adjacent to Fuji Ionomer-Type II and Miracle Mix restorations were significantly less than those of Tytin, Tytin + Copalite, or P30 + Scotchbond.

Because of the rapid technological developments taking place today, it is inevitable that these developments will show themselves in every aspect of human life. These rapid transformations constitute many changes in the structure and living conditions of society. Technology, having started to show itself with all of its aspects especially in the present century, is important in terms of making people reach whatever there is in the field of technology and innovation as soon as possible through mass media. In this context, many countries create systems that produce sports technology by integrating technology into sports. These technologies, which are not limited only to sports products, have also shown their effect on the materials used by referees who are the head of decision mechanisms in sport. The aim of the study is to evaluate the effects of sports, sports education, technological uses, and their effects on sports education. The study is a descriptive one based on qualitative research methods. Document review has been implemented as a data collection method.

The Relationship

The independent effects that different thromboplastins and types of methods have on prothrombin time were studied by analyzing data from a 1977 proficiency testing survey of 2735 laboratories. Each laboratory received three plasma samples with prothrombin times of approximately 12, 16 and 24 seconds which represented normal, partially anticoagulated, and fully anticoagulated plasma respectively. Combinations of 12 different instruments and 12 different thromboplastins were used by the laboratories in evaluating the samples. As determined by a two-way analysis of variance, both the type of thromboplastin and the type of instrument have similar effects upon the prothrombin time. When the mean prothrombin time corrected for independent effects of thromboplastin and method are plotted against the overall mean prothrombin times of each of the three types of plasma samples, the linear relationship between the two is obvious. These relationships can used to convert to a common scale a prothrombin time obtained with any thromboplastin method combination and provides a means for standardizing the prothrombin time test. Retrospective, analysis of data obtained from individual proficiency testing surveys in 1976, 1977, and 1978 suggests that the relationships remained constant during those years. These data suggest that the relationship of any thromboplastin to a thromboplastin standard should be determined independently of the method effect.

ABSTRACTBone is one of the most complex sample materials used for radiocarbon (14C) dating. The installation of the EnvironMICADAS AMS at HEKAL (department of ICER) in 2011 required the adoption of new sample preparation techniques for small bone samples. Since then, hundreds of procedural background and known-age bones have been processed using our modified Longin method (MLM) and dated along with unknown samples. Their results are used in this study to assess the reproducibility of our current bone preparation method and the real uncertainty of the final age result. In addition, using the background samples, which are included in each bone measurement batch, blank correction of the unknown samples could also be performed. The mean F14C value of our bone blanks is generally better than 0.005 (∼42,500 BP) alongside 0.0013 SD. Good reproducibility was confirmed by the results of the laboratory known-age bone as well, where the standard deviation of the mean is better than 0.0025. In addition, the results of the three bone samples used in an ultrafiltration (UF) test study did not show notable differences from the ones obtained by our current protocol in 1σ uncertainty range but more experiments will be performed in the near future.

A cross-sectional, epidemiological study aimed to estimate the prevalence of burden among family caregivers of impaired elderly residents in the city of João Pessoa, and to identify associations between the mean burden and social and demographic characteristics of the elderly and the caregivers. A total number of 240 elderly residents in a previously drawn census tract participated in this research. The sample was composed of 52 elderly and their caregivers. For data collection, a questionnaire was applied with questions on social and demographic characteristics of elderly and caregivers, and the Burden Interview Scale was used. Results showed a high prevalence of burden among caregivers (84.6%), in which a statistically significant association was found with the following characteristics: retired elderly, elderly as head of family, spousal caregivers, and caregivers with less education. The findings of this study may contribute to the development of activities focused on formal and emotional support for the caregivers.

The paper presents mechanical properties of materials used as matrices in diamond impregnated tools. Several powder metallurgy materials were manufactured by the hot press process from various combinations of cobalt (Co SMS, Co Extrafine, Co 400mesh), carbonyl iron (Fe CN) and tungsten (WP30) powders. After consolidation the specimens were tested for density, hardness and tensile properties. The fracture surfaces and materials’ microstructure were observed using the Jeol JSM- 5400 scanning electron microscope and the Leica DM4000 light microscope. The main objective of the work was to determine the effects of the mean particle size of cobalt as well as additions of iron and tungsten on properties of the as-consolidated material.
