Skeletal muscle is readily accessible for non-invasive investigation. While MRI allows for the assessment macroscopic fat distribution, MRS allows for the quantification of ectopic of fat compartments and metabolic profiling of skeletal muscle. Volume selected proton MRS can be applied for the assessment of intramyocellular lipids, creatine, acetylcarnitine, and carnosine. Characterization of glucose fluxes from biopsy specimen could have been replaced by 13C and 31P MRS, which was able to quantify defects of glucose metabolism in diabetes and other insulin resistant states. Basal and stimulated intracellular energy metabolism can be monitored by 31P MRS and combination of spectroscopy and physiologic examinations of the skeletal muscle function and energetic metabolism can help to identify the links between impaired metabolism, function, aging and or training status. Selected issues with respect to methodological issues of skeletal muscle MRS and research oriented applications will be presented and discussed.","PeriodicalId":129350,"journal":{"name":"2019 12th International Conference on Measurement","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116614051","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}

The mortar filled with polyvinyl polymer fibers is intended to use as the thermal contact filler in energetic needles to improve the heat transfer in between the heat exchanger pipe and the stainless steel embodiment. The problem is with the pores of mortar that should be filled by silicone oil that is part of thermal heat silicone compound (Dow Corning) used to improve the heat transfer between the probes and specimen body. Adding some oil-proof layer causes additional disturbance effects at the measurement. The aim of this work was to avoid these effects. The solution was found in the model that accounts the contact resistance between the heat source and specimen as well as the heat capacity of the heat source that are active during the recording of the temperature response to the heat pulse.","PeriodicalId":129350,"journal":{"name":"2019 12th International Conference on Measurement","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126338114","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}

It was found that the increment 0.1 mV masks some features of the maps which are seen only by smaller increment (0.02 mV): the time of appearance of maximum and minimum on the anterior chest, different voltage values of the extrema as normally seen in older subjects, much smaller voltages in the youngest groups compared to the older ones.

The general formulas for the covariance matrix, final uncertainties, and correlation coefficient were determined. The 3D graph shows the correlation coefficients of the output quantities as a function of the type B contributions in the uncertainty of two input quantities.

Diagnostics are especially beneficial if they are followed by effective therapy. A specific example of high-frequency ECG measurement and analysis is linked to cardiac resynchronization therapy. It has been shown that HFECG can be used to select patients who will benefit from resynchronization, to select the optimal pacing technology and, finally, to perform optimal parameter setting.","PeriodicalId":129350,"journal":{"name":"2019 12th International Conference on Measurement","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115428447","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}
