Abstract

The increase of the absolute capacity of temperature control devices used in extracorporeal blood circulation apparatus has necessitated the intensification of heat exchange and, as a consequence, the work of heat exchangers under anisothermal conditions. This concerns mainly thermoelectric temperature control devices. Calculations in the process of their design and, to a greater extent, the optimization of their parameters under the conditions of anisothermality in the soldered joints become far more complicated. The numerical analysis of such thermoelectric device with anisothermal soldered joints has demonstrated the possibility of its analytical optimization by assuming it to be a thermoelectric device working under the average effective values of temperature and the coefficients of electrical characteristics. The results thus obtained allow to considerably decrease labor consumption in designing the above-mentioned devices.

Introduction of community-based skin-to-skin care in rural Uttar Pradesh, India.

OBJECTIVE: Two-thirds of women globally give birth at home, yet little data are available on use of skin-to-skin care (STSC) in the community. We describe the acceptability of STSC in rural Uttar Pradesh, India, and measured maternal, newborn, and ambient temperature in the home in order to inform strategies for introduction of STSC in the community. STUDY DESIGN: Community-based workers in intervention clusters implemented a community mobilization and behavior change communication program that promoted birth preparedness and essential newborn care, including adoption of STSC, with pregnant mothers, their families, and key influential community members. Acceptance of STSC was assessed through in-depth interviews and focus groups, and temperature was measured during home visits on day of life 0 or 1. RESULTS: Incidence of hypothermia (<36.5 degrees C) was high in both low birth weight (LBW) and normal birth weight (NBW) infants (49.2%, (361/733) and 43% (418/971), respectively). Mean body temperature of newborns was lower (P<0.01) in ambient temperatures <20 degrees C (35.9+/-1.4 degrees C, n=225) compared to > or =20 degrees C (36.5+/-0.9 degrees C, n=1450). Among hypothermic newborns, 42% (331/787) of their mothers had a lower temperature (range -6.7 to 0.1 degrees C, mean difference 0.4+/-1.2 degrees C). Acceptance of STSC was nearly universal. No adverse events from STSC were reported. STSC was perceived to prevent newborn hypothermia, enhance mother's capability to protect her baby from evil spirits, and make the baby more content. CONCLUSION: STSC was highly acceptable in rural India when introduced through appropriate cultural paradigms. STSC may be of benefit for all newborns and for many mothers as well. New approaches are needed for introduction of STSC in the community compared to the hospital.

3D quantification of microclimate volume in layered clothing for the prediction of clothing insulation.

Garment fit and resultant air volume is a crucial factor in thermal insulation, and yet, it has been difficult to quantify the air volume of clothing microclimate and relate it to the thermal insulation value just using the information on the size of clothing pattern without actual 3D volume measurement in wear condition. As earlier methods for the computation of air volume in clothing microclimate, vacuum over suit and circumference model have been used. However, these methods have inevitable disadvantages in terms of cost or accuracy due to the limitations of measurement equipment. In this paper, the phase-shifting moiré topography was introduced as one of the 3D scanning tools to measure the air volume of clothing microclimate quantitatively. The purpose of this research is to adopt a non-contact image scanning technology, phase-shifting moiré topography, to ascertain relationship between air volume and insulation value of layered clothing systems in wear situations where the 2D fabric creates new conditions in 3D spaces. The insulation of vests over shirts as a layered clothing system was measured with a thermal manikin in the environmental condition of 20 degrees C, 65% RH and air velocity of 0.79 m/s. As the pattern size increased, the insulation of the clothing system was increased. But beyond a certain limit, the insulation started to decrease due to convection and ventilation, which is more apparent when only the vest was worn over the torso of manikin. The relationship between clothing air volume and insulation was difficult to predict with a single vest due to the extreme openings which induced active ventilation. But when the vest was worn over the shirt, the effects of thickness of the fabrics on insulation were less pronounced compared with that of air volume. In conclusion, phase-shifting moiré topography was one of the efficient and accurate ways of quantifying air volume and its distribution across the clothing microclimate. It is also noted that air volume becomes more crucial factor in predicting thermal insulation when clothing is layered.
