Research has shown that spectroscopic methods have the potential to characterize key plant functional traits such as foliar nitrogen content, specific leaf area (SLA), foliar lignin and cellulose and N15 concentrations. Moreover, it has been shown that variables that can be derived from imaging spectroscopy - foliar nitrogen and lignin/cellulose concentrations - characterize leaf lifespan, influence soil C:N ratios and in combination with disturbance events, may be strong controllers of nutrient cycling in forested landscapes. New methods and improved signal-to-noise of imaging spectroscopy instruments have enabled the assessment of variations in forest functional traits across space and time. However, standardized protocols for pre-processing spectroscopic imagery do not exist, in contrast to spectroscopic methods for chemometric analysis. Give...

The quicker the response, the higher are the chances of saving lives and reducing property damage, lack of precise information greatly hindered relief efforts, Geographic Information System (GIS) and spatial information is a powerful tool in crisis mapping. Mobile, social networking and open source GIS technologies and Volunteered Geographic Information (VGI) present new opportunities for data collection in disaster management. Crowd sourced geospatial information also called neo-geography or VGI in conjunction with Open source geographic information systems (OSGIS) and OGC Open Geo SMS can pool vital information required for disaster response. The 2010 Haiti earthquake has brought about significant change towards the approach of VGI, Ushahidi, NOULA, Open Street Map (OSM), and other volunteer-based efforts has picked up momentum.

Assessment of variations in urban forest growth is critical to urban management and planning, as well as to identify responses to climate and other environmental changes. We estimated annual relative basal area increment by tree rings from 37 plots in Madison, Wisconsin and neighboring municipalities. We related relative basal area growth to variables of vegetation traits derived from remote sensing, including structure (aboveground biomass, diameter, height, basal area, crown width and crown length) from discrete-return airborne lidar, and biochemical variables (foliar nitrogen, carbon, lignin, cellulose, fiber and LMA), spectral indices (NDVI, NDWI, PRI, NDII etc.) and species composition from AVIRIS hyperspectral imagery. Variations in tree growth was mainly correlated with tree species composition (R2 = 0.29, RMSE = 0.004) with coniferous stands having a faster growth rate th...

A fundamental frequency of 2.45 GHz was transmitted at a target and a quadrature homodyne receiver used to sense the received signal from a tag on the target. The setup was used to successfully isolate periodic motion from a tag on a programmable mechanical target and to sense respiratory motion of a human subject, even when the targets were in close proximity to other moving objects.

This paper describes the successful use of heterodyne receiver architecture with Doppler radar to track the heart-rate of a human being using passive body-worn harmonic tags in presence of a controlled noise generator at distances up to 120 cm. The heterodyne system results have been compared with those of a conventional Doppler radar for cardiopulmonary monitoring that fails to isolate the noise from heart-rate in presence of a noise source.

Most of the results published to date have been focused on estimation of the physiological rates, such as respiratory rate and heart rate, with CW and modulated waveforms in various settings. Accurate assessment of chest displacement may take this type of monitoring to the new level, by enabling the estimation of associated cardiopulmonary volumes, and possibly pulse pressure. To obtain absolute chest displacement with highest precision, full nonlinear phase demodulation of the quadrature radar outputs must be performed. The accuracy of this type of demodulation is limited by the drifting received RF power, varying dc offset, and channel quadrature imbalance. In this paper we demonstrate that if relatively large motion is used to calibrate the system, smaller motion displacement may be acquired with the accuracy on the order of 30 µm.

At present, various mechanical, thermal and chemical methods are used for wax management, however these methods can cause additional problems and can be very expensive. Dilution can be used as an alternative or can be combined with current wax-management methods. This paper identifies dilution strategies for a range of waxy crudes from different oil producing regions of the world. Prevention and control of wax deposits by blending heavy fractions of oil with lighter fractions is achieved with tools currently available in the industry. Mixing rules and blending correlations to suppress the wax appearance temperature (WAT) can be developed. A database of fluids with a range of wax contents from different regions of the world was created and used in this analysis. A way forward in modeling, control, and remediation is proposed, and possible areas of further research and development are identified. Expensive thermal and chemical solutions are currently required to produce fluids with high wax content in deep-and ultra deep-water field developments. The results are promising. Unique flow-assurance solutions can be achieved by addition of diluent. Injecting 6 to 23 MSCF Lift gas/1000 bbl crude in low GOR fluids can achieve a WAT reduction of 6 to 7°F. Other diluents evaluated demonstrated that with ratios of 0.5 – 4 bbls of diluent/1000 bbls of crude, a WAT reduction of 6-13°F could be achieved.

Despite the growing share of neonatal mortality in under-5 mortality in the recent decades in India, most studies have focused on infant and child mortality putting neonatal mortality on the back seat. The development of focused and evidence-based health interventions to reduce neonatal mortality warrants an examination of factors affecting it. Therefore, this study attempt to examine individual, household, and community level factors affecting neonatal mortality in rural India. Data and methods. We analysed information on 171,529 singleton live births using the data from the most recent round of the District Level Household Survey conducted in 2007-08. Principal component analysis was used to create an asset index. Two-level logistic regression was performed to analyse the factors associated with neonatal deaths in rural India. Results. The odds of neonatal death were lower for neonates born to mothers with secondary level education (OR = 0.60, p = 0.01) compared to those born to illiterate mothers. A progressive reduction in the odds occurred as the level of fathers' education increased. The odds of neonatal death were lower for infants born to unemployed mothers (OR = 0.89, p = 0.00) compared to those who worked as agricultural worker/farmer/laborer. The odds decreased if neonates belonged to Scheduled Tribes (OR = 0.72, p = 0.00) or 'Others' caste group (OR = 0.87, p = 0.04) and to the households with access to improved sanitation (OR = 0.87, p = 0.02), pucca house (OR = 0.87, p = 0.03) and electricity (OR = 0.84, p = 0.00). The odds were higher for male infants (OR = 1.21, p = 0.00) and whose mother experienced delivery complications (OR = 1.20, p = 0.00). Infants whose mothers received two tetanus toxoid injections (OR = 0.65, p = 0.00) were less likely to die in the neonatal period. Children of higher birth order were less likely to die compared to first birth order. Conclusion. Ensuring the consumption of an adequate quantity of Tetanus Toxoid (TT) injections by pregnant mothers, targeting vulnerable groups like young, first time and Scheduled Caste mothers, and improving overall household environment by increasing access to improved toilets, electricity, and pucca houses could also contribute to further reductions in neonatal mortality in rural India. Any public health interventions aimed at reducing neonatal death in rural India should consider these factors.

Low use of maternal healthcare services is one of the reasons why maternal mortality is still considerably high among adolescents mothers in India. To increase the utilization of these services, it is necessary to identify factors that affect service utilization. To our knowledge, no national level study in India has yet examined the issue in the context urban adolescent mothers. The present study is an attempt to fill this gap. Data and Methods. Using information from the third wave of District Level Household Survey (2007-08), we have examined factors associated with the utilization of maternal healthcare services among urban Indian married adolescent women (aged 13-19 years) who have given live/still births during last three years preceding the survey. The three outcome variables included in the analyses are 'full antenatal care (ANC)' , 'safe delivery' and 'postnatal care within 42 days of delivery'. We have used Chi-square test to determine the difference in proportion and the binary logistic regression to understand the net effect of predictor variables on the utilization of maternity care. Results. About 22.9% of mothers have received full ANC, 65.1% of mothers have had at least one postnatal checkup within 42 days of pregnancy. The proportion of mother having a safe delivery, i.e., assisted by skilled personnel, is about 70.5%. Findings indicate that there is considerable amount of variation in use of maternity care by educational attainment, household wealth, religion, parity and region of residence. Receiving full antenatal care is significantly associated with mother's education, religion, caste, household wealth, parity, exposure to healthcare messages and region of residence. Mother's education, full antenatal care, parity, household wealth, religion and region of residence are also statistically significant in case of safe delivery. The use of postnatal care is associated with household wealth, woman's education, full antenatal care, safe delivery care and region of residence. Conclusion. Several socioeconomic and demographic factors affect the utilization of maternal healthcare services among urban adolescent women in India. Promoting the use of family planning, female education and higher age at marriage, targeting vulnerable groups such as poor, illiterate, high parity women, involving media and grass root level workers and collaboration between community leaders and health care system could be some important policy level interventions to address the unmet need of maternity services among urban adolescents.
