The objective of this study was to determine the fatty acid composition of newly developed tissues of germinated soybean seeds. Five soybean accessions with varied fatty acid composition were allowed to germinate in sand under greenhouse conditions. Seedlings were picked up after 4, 6, 8, 10 and 12 days of germination and freeze dried. The fatty acid composition of the newly developed tissues was analyzed by gas chromatography. Significant variation in fatty acid composition was observed between accessions, days of germination, and variety x day of germination in whole and the cotyledons. In the case of newly developed five tissues, significant variation in fatty acid composition were observed between days of germination except oleic acid for root, hypocotyl and epicotyl stem and except stearic acid for hypocotyl and unifoliate leaves while all the parameters were significantly different for accession. Significant interactions of accession and days of germination were observed for palmitic, linoleic and linolenic acid in all tissues; only for oleic acid in hypocotyl, epicotyl and unifoliate leaves; and only for stearic acid in root, hypocotyl, epicotyl and unifoliate leaves. During germination, the fatty acid composition of newly developed tissues changed dramatically but whole seedlings and cotyledons changed slightly. These tissues contained five major fatty acids as found in original seeds, but compositions were totally different from that of the seed: higher in palmitic, stearic and linolenic acid and lower in oleic and linoleic acid. New tissues conserved their fatty acid compositions regardless of genotypic variation in the original seeds.

The aim was to evaluate the skin permeation and accumulation profiles of a highly lipophilic fatty ester using the combination of various permeation enhancing techniques to study the potential of highly lipophilic fatty esters as local topical agents. Permeation and accumulation profiles of ketorolac stearate (C18:0) were studied using solubility improved formulation, supersaturated solution of permeant in enhancer vehicle, lipophilic receptor solution, enhancer pretreatment, and the removal of stratum corneum and delipidization of skins. Impermeability and minimal skin accumulation of ketorolac stearate could delineate a preliminary possibility for designing safer topical agents without systemic absorption.

KRISHNA, KONDA HARI,NAGPAL, TAPSI,BABU, Y. SURESH International Journal of Computer ScienceNetwork S 2022 International journal of computer science and netw Vol.22 No.7
In the previous years, Wireless Sensor Networks (WSNs) have increased expanding consideration from both the clients and scientists. It is utilized as a part of different fields which incorporate ecological, social insurance, military and other business applications. Sensor hubs are battery fueled so vitality imperatives on hubs are extremely strict. At the point when battery gets released, sensor hub will get detached from remaining system. This outcomes in connection disappointment and information misfortune. In a few applications battery substitution is likewise impractical. Consequently, vitality proficient strategies ought to be outlined which will upgrade lifetime of system and precise information exchange. In this paper, diverse wellsprings of vitality dissemination are recorded trailed by vitality effective systems to improve lifetime of the system.

Carbon nanotubes (CNTs) in a chemiresistor setup have been widely explored in bio/chemical sensing. Detection of certain molecules with environmental and health related importance such as 9- anthracenecarboxylic acid, diclofenac sodium, and curcumin using electrochemical methods/unfunctionalized CNTs suffer from lack of response, high limit of detection (LOD) and poor selectivity. The key to overcome these issues is to decorate CNTs with host (receptor) molecules like b-cyclodextrin (b-CD) that interact with guest (target) molecules by hosteguest complex formation. To improve guest recognition, and consequently, the sensor performance, effective immobilization of b-CD on the CNT surface using a non-covalent bridging molecule such as 3, 4, 9, 10-perylene tetracarboxylic acid (PTCA) is required. Furthermore, the selectivity can be assessed using the conductance correlation patterns of different host eguest systems in conjunction with a pattern classification tool. Our results indicate that PTCA linked b- CD-decorated CNT chemiresistors showed a good linear detection range (~100 pMe100 nM), sensitivity (~3 103e9 102 nM1) and LOD (~62 pMe101 nM), compared to devices without PTCA, in the detection of the guest molecules. The distinction in correlation patterns of different hosteguest systems was corroborated by pattern classification yielding a classification accuracy, sensitivity, and specificity of ~91.83%, ~90.13%, and ~85.39%, respectively.

Fatty acid composition and C18:2:C18:3 of soybean seed and sprout is important for soy-industries to manufacture quality products. Six soybean varieties were analyzed by gas chromatography to determine fatty acid composition and linoleic to linolenic acid ratio (C18:2:C18:3) in seed, sprout, and their structural parts. In the case of whole seed and its structural parts, significant variation in fatty acid composition and C18:2:C18:3 were observed between varieties except palmitic acid (C16:0), while all the parameters were significantly different for seed parts. Significant interactions of variety with seed parts were observed for oleic acid (C18:1), C18:2 and C18:2:C18:3. The highest saturated fatty acid, C18:1 and polyunsaturated fatty acid were recorded in seed coat, cotyledon, and seed axis, respectively. The lowest C18:2:C18:3 was found in seed axis. In the case of sprout study, variety had significant effect on all the parameters observed for whole sprout, cotyledon, root, and except C18:3 for hypocotyl. Culture days had significant effect on C16:0, C18:2 and C18:3 in whole sprouts, while only on 18:3 and C18:2:C18:3 in cotyledon. For hypocotyl, culture days had significant effect on 18:1, 18:2 and 18:2:18:3, however, C16:0, C18:1, C18:3, and C18:2:C18:3 were significantly different in root. In sprout, days and variety interacted significantly for C16:0, C18:3 and C18:2:C18:3, and C18:1, C18:2, C18:3, and C18:2:C18:3, respectively for whole, cotyledon, and root. The significantly lowest C18:2:C18:3 (1.1) was observed in hypocotyl and root of Hwangkeumkong in 5 days. Knowledge of fatty acid composition and C18:2:C18:3 of seed, sprout, and their parts could be applicable for oil and other soy-food industries to make quality products.

A Comparative Analysis on Performance of Wireless Sensor Networks Routing Protocols
KRISHNA, KONDA. HARI,NAGPAL, TAPSI,BABU, Y. SURESH International Journal of Computer ScienceNetwork S 2022 International journal of computer science and netw Vol.22 No.7
The common goals of designing a routing algorithm are not only to reduce control packet overhead, maximize throughput and minimize the end-to-end delay, but also take into consideration the energy consumption. Scalability is an important factor in designing an efficient routing protocol for wireless sensor networks (WSN's). Three metrics (power consumption, time of transmission and packet loss rate) are used in order to compare three routing protocols which are AODV, DSDV and LEACH.

<P>Phase solubility behavior of coenzyme Q10 (CoQ10) at 25 °C in various molar solutions of poloxamer 188 (P188) in water was observed and their binary solid dispersions (BSD) at different weight ratios were prepared by a simple, rapid, cost effective, uncomplicated and potentially scalable low temperature melting method. BSDs were characterized by scanning electron microscopy (SEM) and differential scanning calorimetry (DSC), and evaluated for improved solubility at 25 °C and 37 °C and <I>in-vitro</I> release of CoQ10 at 37 °C in distilled water. Solubility of CoQ10 increased with increasing concentrations of P188 in water. Gibbs free energy (Δ<I>G</I>°<SUB>tr</SUB>) values were all negative indicating the spontaneous nature of CoQ10 solubilization and decreased with increasing concentration of P188 demonstrating that the reaction conditions became more favorable as the concentration of P188 increased. DSC and SEM analysis indicated that the homogeneity of dispersion was not at the molecular level. However, BSDs exhibited a remarkably improved aqueous solubility and dissolution of CoQ10.</P>
