“Jatropha curcas (L.) trees under north Indian conditions (Lucknow) GDC-0994 price produce fruits in two major flushes, once during autumn-winter (October-December). The leaves at this time are at the senescence stages and

already shedding. The second flush of fruit setting occurs during the summer (April-June) after the leaves have formed during spring (March-April). Photosynthetic performance of detached jatropha fruits was studied at three developmental stages, immature, mature and ripe fruits. Studies were made in both winter and summer fruits in response to light, temperature https://www.selleckchem.com/products/lazertinib-yh25448-gns-1480.html and vapour pressure deficit (VPD) under controlled conditions to assess the influence of these environmental factors on the photosynthetic performance of jatropha fruits. Immature fruits showed high light saturating point of around 2000 mu mol m(-2) s(-1). High VPD did not show an adverse effect on the fruit A. Stomata! conductance (g(s)) showed an inverse behaviour to increasing VPD, however, transpiration

(E) was not restricted by the increasing VPD in both seasons. During winter in absence of leaves on the jatropha tree the fruits along with the bark contributes maximum towards photoassimilation. Dark respiration rates (R-d) monitored in fruit coat and seeds independently, showed maximum R-d in seeds of mature fruit and these were about five times more than its fruit coat, reflecting the higher energy requirement of Sapitinib clinical trial the developing fruit during maximum oil synthesis

stage. Photosynthesis and fluorescence parameters studied indicate that young jatropha fruits are photosynthetically as efficient as its leaves and play a paramount role in scavenging the high concentration of CO2 generated by the fruit during respiration.

“The concepts of effective thermal conductivity and interfacial thermal contact resistance in composite media are applied to study heat transport in polymer-dispersed liquid crystals (PDLC). In these systems, the thermal properties of liquid crystal inclusions are changed by an imposed electric field. The photopyroelectric (PPE) technique with a cell allowing the application of an electric field to the sample is used to measure the thermal parameters. A model based on effective medium approximation is used to assess the impact of interfaces on the flow of heat through the determination of the Kapitza radius. It was found that the effect of interfaces becomes dominant compared to the volume conduction of the droplet when the liquid crystal (LC) droplet radius becomes smaller than 1 micron.
