As it is well accepted that physiological compensatory adaptations to circulatory shock involve blood flow redistribution and increase in sympathetic stimulation, we recently investigated if galvanic skin response (GSR) or electro-dermal activity (EDA), a measure of sympathetic stimulation, could give information about the impending danger of acute hypotensive episode or circulatory collapse (Subramanya and Mudol, 2012). In this current study, a low-cost wearable device was developed and tested to help progress towards a system for predicting blood pressure (BP) and cardiovascular dynamics. In a pilot study, we examined hypotheses about the relation between GSR values and four BP indexes (systolic BP, diastolic BP, mean arterial pressure and pulse pressure) in apparently healthy human volunteers before and immediately after treadmill exercise. All four BP indexes had significant relationship with GSR, with pulse pressure possibly the strongest predictor of variations in the GSR and vice-versa. This paper opens up opportunities for future investigations to evaluate the utility of continuous monitoring of GSR to forecast imminent cardiovascular collapse, AHE and shock, and could have far-reaching implications for ICU, trauma and critical care management.","PeriodicalId":313185,"journal":{"name":"2013 Annual IEEE India Conference (INDICON)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121610023","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}

Heart rate variability (HRV) parameters of fetal are measured for obese & non-obese mother prior to delivery with Doppler ultrasound method. We studied 64 maternal abdominal Doppler ultrasound signals. From these, we identify 41 subjects of whose body mass index (BMI) ranging from 20 to 37. The R-R interval variability which shows the variation between consecutive heart beats, change over time was eventually adopted to calculate for time-domain, frequency domain and non linear analysis. Based on frequency analysis, the ranges of the LF and HF domains were defined as 0.04-0.15 and 0.15-0.4 Hz, respectively. We defined low frequency/high frequency (LF/HF) ratio as a index of sympathetic activity. The value of LF/HF ratio [Nonparametric Fast Fourier Transform (FFT) Based method] in normal pregnancy group displayed clearly decreasing trend with body mass index (BMI) y = - 0.013x + 0.965; R2 = 0.040 (one-way ANOVA: P <; 0.0001). The value of LF/HF ratio [Parametric Autoregressive (AR) Based] in normal pregnancy group displayed clearly decreasing trend with body mass index (BMI) y = - 0.011x + 0.8555; R2 = 0.051 (one-way ANOVA: P <; 0.0001). In consultation with gynecologists and child specialist it has been verified that the new born babies have more neurological problems following deliveries from obese mothers compared with deliveries from non-obese mothers.","PeriodicalId":313185,"journal":{"name":"2013 Annual IEEE India Conference (INDICON)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124229530","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 lack of utilities of algae and resulting sludge has lead to anoxia and GHG emissions. Environmental friendly ways of sludge and algal biomass utilities as well as disposal are scant. Testing for biofuel and thermal properties can be beneficial to meet the energy requirement to run treatment plants that might have better fuel value to increase the net energy gain in the system. As the volume of algal biomass and quantity of sludge has increased over the past few years, sustainable means of biomass and sludge utilization needs to be devised for beneficial purposes, to keep the surface waters clean and regulate the biomass productivity of such systems. Therefore the biomass and sludge characterization becomes imperative for any further utilities. In the present study the indigenous suspended algae and the algal bioreactor sludge were characterized for the different functionalities and presence of bio-chemicals (carbohydrates, proteins and lipids) through Infrared Analysis (ATR-FTIR). The total lipids and fatty acid methyl esters (FAME) composition were studied. The heat values and thermal decomposition pattern were analyzed by [Thermogravimetry (TGA)/Differential Thermal Analysis (DT) and Differential Scanning Calorimetry (DSC)]. The algae were found to have a better total lipid content of >34 % compared to 22% in case of wastewater sludge with quality FAME for better biofuel properties. However there were higher number of FAME in wastewater sludge (>30) where C16 and C18 members dominated. Algal biomass showed higher calorific value of 17.96 MJkg-1 compared to 10.33 MJkg-1 of wastewater sludge.","PeriodicalId":313185,"journal":{"name":"2013 Annual IEEE India Conference (INDICON)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130717238","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}
