  • This paper evaluates the applicability of wave-based nondestructive methodologies and a penetration test for compaction quality measurements during road construction. To evaluate the physical and mechanical properties of compacted subgrade soil layers, soil stiffness gauge (SSG), time domain reflectometry (TDR), and miniature electro-mechanical systems (MEMS) accelerometers were used to nondestructively evaluate the soil response during and after compaction and dynamic cone penetrometer (DCP) profiles were used to evaluate the soil shear strength after compaction was completed. At the field site, two types of soils were compacted with four different compaction equipments and energies. Field testing results indicate that soil parameters evaluated by different testing methods, which are SSG, TDR, MEMS accelerometer, and DCP, are highly correlated. In addition, it is shown that the physical and mechanical tests deployed in this study can be used as alternative methods to the conventional compaction quality evaluation methods when assessing the overall quality and the engineering response of compacted lifts.

  • Video Content owners seek to squeeze the maximum amount of revenue from their assets via distribution into more territories. Digital Cinema Package(DCP), trusted solution to distribute protected content to theaters, caters to relatively small user base, which limits revenue. With the growth of the Internet & other digital media, the economics of media content has changed dramatically. Security remains main concern to deliver content to millions of consumers using intelligent digital display devices like Tablets, Smartphones, Smart TVs, Desktop & Laptop. By making the video content available to this segment securely, content owners will benefit from increased revenue. Through this paper we propose Open Source HomeDCP model to distribute the content to home users for offline viewing. We propose to include other open source CODEC than JPEG2000/MPEG2, which are specifically designed for theatrical performance. Final image size will be further reduced considering the display device resolution where video will be finally played. Key Delivery Message(KDM) system to be altered to suit new devices. This will be a big boost to Content Economy as content owners would be able to distribute the content securely to the wider audience & ensure more revenue.

  • To investigate the industrial availability of liquid fermentation (PL-ferment) by Phellinus linteus mycelium as a postbiotics for the inhibition of inflammation, PL-ferment was fractionated into culture supernatant (CS), hot-water extract (HW) from PL-ferment, EtOH-precipitate (CP) fractionated from HW, and the dialysate (DCP) of CP. Compared to the other fractions, DCP which is expected to contain exopolysaccharide (EPS) as the major component, significantly decreased the production of NO, IL-6, and MCP-1 in LPS-induced RAW 264.7 cells, and IL-6 and IL-8 in TNF-α and IFN-γ-induced HaCaT cells. The general component analysis results showed that no significant difference in components was observed between the fractions, whereas sugar composition analysis revealed that DCP had decreased glucose and increased mannose contents compared to the other fractions. This suggests that mannose played an important role in the anti-inflammatory activity of the active fraction, DCP. Molecular weight distribution analysis revealed that DCP was mainly composed of low-molecular-weight material-removed high-molecular-weight polysaccharides of 18-638 kDa, suggesting that EPS originated from P. linteus EPS. In conclusion, our results suggest that the DCP of P. linteus mycelium fermentation using the anti-inflammatory activity could be used industrially as postbiotic material.

  • The effects of temperature and curing systems on the compression set of natural rubber (NR) at constant load were investigated. NR was compounded with various amounts of sulfur and DCP in order to obtain various crosslink densities and curing systems. Compression sets at constant load were compared with those at constant strain. Compression set at constant load was more affected by changes in crosslink density than compression set at constant strain, due to the differences of exerted strain energy density. Compression set of sulfur cured NR under constant load was increased with increasing load and temperature, but the compression set of DCP cured NR was not changed by increasing load and temperature.

  • Polychlorinated naphthalenes (PCNs) formed along with dibenzo-p-dioxin and dibenzofuran products in the slow combustion of dichlorophenols (DCPs) at $600^{\circ}C$ were identified. Each DCP reactant produced a unique set of PCN products. Major PCN congeners observed in the experiments were consistent with products predicted from a mechanism involving an intermediate formed by ortho-ortho carbon coupling of phenoxy radicals; polychlorinated dibenzofurans (PCDFs) are formed from the same interemediate. Tautomerization of the intermediate and $H_2O$ elimination produces PCDFs; alternatively, CO elimination to form dihydrofulvalene and fusion produces naphthalenes. Only trace amounts of tetrachloronaphthalene congeners were formed, suggesting that the preferred PCN formation pathways from chlorinated phenols involve loss of chlorine. 3,4-DCP produced the largest yields of PCDF and PCN products with two or more chlorine substituents. 2,6-DCP did not produce tri- or tetra-chlorinated PCDF or PCN congeners. It did produce 1,8-DCN, however, which could not be explained.

  • With a purpose of finding out the effects of cattle slurry application on thc nutrient contents of herbages and energy productivity in grassland, a field experiment was conducted with two times and five levels of cattle slurry application. The experimental field was designed in a split-plot with threc replications, and lasted from September, 1986 to October, 1990 at the Livestock Experiment Station in Suweon, The results obtained are summarized as follows: 1. The net energy(NEL, StE and TDN) contents of grasses in the plots with cattle slurry application just after cutting were slightly higher when compared to manuring 15 days after cutting. but DCP content has reverse trend. 2. Average net energy(NEL. StE and TDN) and DCP production of the plot with cattle slurry application 15 days after cutting were insignificantly increased by 26 % than those of manuring just after cutting. The energy and DCP yields in the plot with cattle slurry and with slurry + mineral fertilizer were decreased by 21 -27 % and 8- 11 %, respectively than those of the plot with single dressing of mineral fertilizer. 3. Mineral contents of grasses were not significant difference among the treatments of cattle slurry. but considering nutrient balance of animals, application of cattle slurry of 30-$60m^3$/ha with mineral fertilizer was profitable as compared to the other treatments.

  • Objective: To assess the diagnostic and prognostic value of AFP and des-gamma-carboxyprothrombin (DCP) in combination and alone for hepatocellular carcinoma. Materials and Methods: A case control study carried out in the Department of Biochemistry of Manipal College of Medical Sciences, Pokhara, Nepal between $1^{st}$ January 2010 and $31^{st}$ December 2011. The variables collected were age, gender, BMI, total proteins, albumin, AST, ALT, total bilirubin, DCP, AFP. Approval for the study was obtained from the institutional research ethical committee. Estimation of AFP was performed by ELISA reader for all cases. Analysis was done using descriptive statistics and confidence interval (CI). The data was analyzed using Excel 2003, R 2.8.0 Statistical Package for the Social Sciences (SPSS) for Windows Version 16.0 (SPSS Inc; Chicago, IL, USA) and the EPI Info 3.5.1 Windows Version. Results:The mean age of HCC cases was $53.6{\pm}14.93$ yrs. The percentage of females was less than males in both cases (23%) and controls (29%). The specificity of DCP reached 100% when its values was equal or greater than 150 (MAU/ml) for 0, 3, 6, 9, 12 months preceding the diagnosis of HCC. Similarly, the specificity for AFP was also nearly 100% when its value was equal or greater than 200 ng/ml 0, 3, 6, 9, 12 months earlier to the finding of HCC. The specificity of DCP (${\geq}40MAU/mL$) and AFP(${\geq}20$ ng/mL) in combination was 93%, 97%, 95%, 96%, 97% in respect to 0, 3, 6, 9, 12 months prior to the diagnosis of HCC. Conclusion: The combination of both DCP and AFP will improve the finding of initial HCC and the sensitivity of these markers was utmost at the time of HCC identification and noticeably lesser at former time points.

  • There is a big attention to digital convergence products(DCP) nowadays. However, consumers' response on the DCP is not always positive. These products may not match consumers' value and consumers may not know how to use them, because the DCP is generally innovative products. DCP marketers should learn that why consumers do not purchase them. Thus, this paper examines and identifies the consumers' purchase-avoiding psychological factors and antecedents on DCP. In detail, It is empirically checked that how the relationship between purchase-preventing factors such as complexity, incongruence, uncertainty, and unreasonability and purchase-avoiding psychological factors such as dissonance, innovation resistence, and perceived loss is. Also, these purchase-avoiding psychological factors' influence on the purchase-intention is empirically checked. As results, complexity and incongruence have an effect on the innovation resistence significantly. Uncertainty and unreasonability influence perceived loss variable. Unreasonability also influences consumers' cognitive dissonance variable. Additionally, cognitive dissonance have an influence on innovation resistence positively, and such innovation resistence influence consumer's purchase-intention negatively. Therefore, marketers should think twice about the roles of these purchase-preventing factors before launching.

  • An investigation was made to evaluate the native range of western India in terms of nutrient supply during different physiological stages in goats. One hundred female and 5 male Kutchi adult goats were grazed on a 35 ha plot of native range. They were maintained on sole grazing. Four experiments, one in a defined physiological stage was carried out. Stage I, when maximum number of females were bred; stage II, when bucks were used for breeding purpose; stage III, 3-months old (weaner) kids were allowed to graze on ranges and stage IV, when the goats were in early stage of lactation. During oestrous period, diet contained 15.2% crude protein (CP), 54.0% neutral detergent fibre (NDF), 31.5% acid detergent fibre (ADF) and 12.6% acid detergent lignin (ADL). Digestibility coefficient of dry matter (DM), CP, NDF and ADF was 0.586,0.531, 0.431 and 0.239, respectively. DM, digestible crude protein (DCP) and metabolizable energy (ME) intakes were $82.7,\;6.71g\;kg^{-1}\;W^{0.75}$ and $0.99MJ\;kg^{-1}\;W^{0.75}$. Diet of buck was constituted by $230g\;kg^{-1}$ DM of grasses and forb and $770g\;kg^{-1}$ DM of tree foliage. CP, NDF, ADF and ADL contents of the diet were 13.6, 57.8, 43.5 and 20.0%, respectively. DM, DCP and ME intakes were $57.9,\;4.13g\;kg^{-1}\;W^{0.75}$ and $0.82MJ\;kg^{-1}\;W^{0.75}$. Digestibility coefficient of CP, NDF and ADF were 0.496, 0.432 and 0.346, respectively. Diet of kids was constituted by Prosopis cineraria ($900g\;kg^{-1}DM$) and Zizyphus nummularia ($100g\;kg^{-1}DM$) leaves. Digestibility of CP, NDF and ADF were 0.456, 0.415 and 0.201, respectively. DM, DCP and ME intakes were $85.8,\;6.44g\;kg^{-1}\;W^{0.75}$ and $1.22MJ\;kg^{-1}\;W^{0.75}$. Lactation phase of goat fell between October-December and tree foliage formed the major portion of the diet. Diet of lactating goat contained only 6.8% CP and 16.5% ADL. Digestibility of DM, CP, NDF and ADF was 0.567, 0.221, 0.307 and 0.233, respectively. DM, DCP and ME intakes were $108.2,\;1.62g\;kg^{-1}\;W^{0.75}$ and $1.50MJ\;kg^{-1}\;W^{0.75}$, respectively. Present study establishes that goats on semiarid range with sufficient number of fodder trees were able to meet the nutrient requirement of ewes during oestrous and bucks during breeding season. However, during lactation and active growth phase, only DM requirement is met. Thus, it is recommended to supplement concentrate mixture to goats grazing on range during lactation and growth phase.
