This PC device is applied as a sensor to detect the concentration of NO2 gas dissolved in specific reagent Griess Saltzmann. From spectroscopic measurement it is found that the absorption spectral of the NO2 gas to be in the range of light source wavelength 500–550 nm. Based on this fact, we set up the PCs to admit a photonic pass band (PPB) at a wavelength of 550 nm. To enhance the performance, the device is designed to work on the basis of both absorption and PPB variation phenomena. The experimental results show that the response of the device correlates linearly with the concentration of dissolved NO2 gas and exhibits high sensitivity with coefficient determination of 99%.

The result of insufficient action of insulin is an increase in blood glucose concentration. The diagnosis of Diabetes must always be established by a blood glucose measurement made in an accredited laboratory. The alternative way to measure a deficiency of insulin from the Beta-cells of pancreatic islets uses iris diagnosis. Evaluating the iris is done by detecting the presence of some broken tissue in iris. However, conventional iris diagnosis is always concerned with the identification of syndromes rather than with the connection between abnormal iris tissue appearances and diseases. In this paper, we present a novel computerized iris inspection method aiming to address these problems for detecting insulin deficiency from the Beta-cells of pancreatic islets. First, quantitative features, textural measures are extracted from iris images by using popular digital image processing techniques. Then, Neighborhood based Modified Backpropagation using Adaptive Learning Parameters (ANMBP) method is employed to model the relationship between quantitative features and pancreatic abnormalities as caused of insulin deficiency. The effectiveness of this method is tested on 12 patients with Diabetes, and the diagnostic results predicted by the previously trained ANMBP classifiers are compared with the calculation of HOMA-B, obtained 83.3% accuracy in detecting pancreas disorders.","PeriodicalId":395673,"journal":{"name":"2011 2nd International Conference on Instrumentation, Communications, Information Technology, and Biomedical Engineering","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115764439","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To preserve tooth structure, repair of existing restorations can be done by relayering (composite-to-composite-bonding). This study compares shear and microtensile failure in composite-to-composite-bonding. Disk-shaped and rectangular-blocks of a nanohybrid and nanofilled composite were prepared for shear and microtensile measurements, respectively. Half of all specimens were aged using thermocycling. Non-aged and thermocycled specimens were conditioned by intermediate-adhesive-resin-application (IAR-application) or silica-coating and silanization followed by IAR-application (SC-application). Resin composites, of the same kind as the substrate, were adhered onto the substrates and shear or microtensile forces applied to the interface. Significant differences between shear and microtensile failure stresses, effects of conditioning, aging and composite types were observed. Mean failure shear stresses (7 – 28 MPa) were significantly lower than microtensile ones (32 – 53 MPa), regardless of aging or conditioning, with average standard deviations approaching 50%. The dependability of the bonds, indicated by its Weibull modulus, was similarly low in shear and microtensile modes. Failures after shear were more frequently cohesive than after application of a tensile force, except in thermocycled composites after IAR-application. Clinically, restorations are mainly exposed to shear and shear evaluations are to be preferred over microtensile ones, also since Weibull moduli are similar for both modes. Hence, considering the high percentages of cohesive failure in shear combined with the low Weibull moduli, this study indicates that the least dependable link in composite-to-composite-bonding is the composite itself and not the adhesive interface, with the exception of bonding created after thermocycling by IAR-application.","PeriodicalId":395673,"journal":{"name":"2011 2nd International Conference on Instrumentation, Communications, Information Technology, and Biomedical Engineering","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114984293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
