P2P TV: Evaluating Content Delivery and User Experience

In this paper, we present findings from empirical studies on end users' experiences of peer-to-peer (P2P) networked television services. To explore the quality of user experience and content consumption in the evolving TV system, we have developed a peer-to-peer social media service prototype, which can be used both with regular home computer networks and on mobile devices, providing users a real pervasive, ambient media experience. Our primary goal is to create an understanding of the factors that shape P2P TV experience as a basis for the future design of NextShare, a peer-to-peer social media service. Through this research, we concluded that P2P technology can provide a reliable mechanism for ingestion of time-based TV program as well as VOD content via the Internet. P2P technology is especially suitable for large media content providers. However, in order to create a real business value out of the service, new, innovative content production models and types need to be developed

Are different income sources fungible? The effects of agricultural subsidy and disaster relief on household consumption in China

This paper uses panel data from a sample of farm households in the northeastern China to examine the non-fungibility of different income sources. The results show the private transfer income has a high and significant impact on household consumption while agricultural subsidy and disaster relief have insignificant impacts. Empirical findings prove that the Behavioral Life Cycle Hypothesis is more practical than the Life Cycle Hypothesis. Moreover, they provide important macro policy implications as for how to stimulate farm consumption and expand domestic demand and encourage economic growth

Extraction and separation of zinc, lead, silver, and bismuth from bismuth slag

The present paper deals with the extraction and separation of zinc, lead, silver, and bismuth from a refractory bismuth refining slag via a hydrometallurgical route. The process consists of a preliminary leaching of zinc with water, followed by the selective leaching of lead and silver with a calcium chloride solution, leading to the crystallization of lead chloride and the cementation of silver. The diagrams of the total concentrations of [Pb]/[Ag] versus [Cl-] and temperature in the Pb/Ag-Cl-H2O system were drawn, respectively, to determine the optimum concentration of leaching agent and leaching temperature. The potential-pH diagram of the Pb/Ag/Bi-H2O system indicates that the preferential leaching of lead and silver could be achieved. Finally, 98.8% of lead and 90.4% of silver were selectively removed by further leaching the water leaching residue with 400 g/dm3 of CaCl2 solution at pH 4.5 and 80 °C, while only 3.7% of bismuth was leached in this stage. Fifty-nine percent of lead in the leach liquor was separated out as PbCl2 by natural cooling. Ninety-five percent of silver in mother liquor was recovered by cementation with a lead sheet. The depleted CaCl2 solution can be sent to the leaching step again to close the loop

Rubidium extraction from mineral and brine resources: A review

Rubidium is a rare alkali metal with high economic value and application potential. It is mainly recovered from the intermediate products of lithium/cesium extraction from lepidolite/pollucite. The application potential and extraction difficulties of rubidium have necessitated the development of new methods for the extraction of rubidium from resources. However, to the best of our knowledge, the extraction of rubidium has received less attention than that of the main group elements, lithium and potassium, and there is no review of the rubidium extraction process to date. Hence, this state-of the-art review addresses the development of rubidium extraction technology and points out the current barriers and potential strategies to achieve the effective rubidium extraction. The review includes the occurrence of rubidium in various resources, and the processes and mechanism of rubidium extraction from mineral (lepidolite, zinnwaldite, pollucite, kaolin, muscovite and biotite) and brine (salt lake and seawater) resources. It is expected that the review can provide insights for the efficient utilization of the rubidium resources

Studies on the toxic effects of La(3+) to Tetrahymena thermophila by microcalorimetry

The toxic effects of La(3+) on Tetrahymena thermophila have been studied by microcalorimetry at 28 degrees C. The metabolic rate constant (r) and peak time were linked to the concentration of La(3+). The changes of metabolic rate constant indicated that low-concentration La(3+) (0-75 mg/L) had no significant effects on the metabolism of Tetrahymena cells but high-concentration La(3+) (100-175 mg/L) could inhibit their metabolism. From the results obtained by cell counting and fluorescence depolarization measurements, the inhibition of metabolism resulted from the decrease in cell number and the reduction in cell membrane fluidity. According to the results, it is clear that the metabolic mechanism of Tetrahymena cells has been changed with the addition of high-concentration La(3+). In addition, microcalorimetry of Tetrahymena could be a sensible, easy-to-use, and convenient method for monitoring the potential effects of rare earth elements on cells and the freshwater ecosystem

Lateral and longitudinal variation in phosphorus fractions in surface sediment and adjacent riparian soil in the Three Gorges Reservoir, China

Hydrological regimes have been significantly altered since the Three Gorges Dam (TGD) raised the water level of the reservoir to the maximum design level of 175 m in October 2010. This change might greatly influence the forms of phosphorus (P) in the sediment and the adjacent riparian soil. The purpose of this study was to reveal the lateral (sediment, water-level-fluctuation zone soil, and upland soil) and longitudinal (from the end of backwater area to the TGD) trends in P factions. Samples from 11 sites located along the main stem and ten sites located along eight tributaries were collected in June 2017. The P fractions were determined using the Standards, Measurements, and Testing (SMT) protocol. The results showed that the order of increase for average pH values was sediment (7.58 +/- 0.62), WLFZ soil (7.44 +/- 0.29), and adjacent upland soil (7.20 +/- 0.68). The total organic carbon in the sediment was also highest with an average of 9.15 +/- 2.97 mg g(-1). The average concentrated HCl-extractable P (total P), organic P (OP), inorganic P (IP), HCl-extractable P (HCl-P), and NaOH-extractable P (NaOH-P) were 630.02 +/- 212.24, 161.89 +/- 90.77, 468.13 +/- 194.92, 335.65 +/- 159.88, and 51.40 +/- 36.20 mg kg(-1), respectively. The concentration of both total P and NaOH-P in the sediment of the main stem exhibited an increasing trend from the backwater area to the TGD. The average concentration of P species in the sediment was higher than those in the upland soil and the water-level-fluctuation zone (WLFZ) soil. For all the sediment and soil samples, the rank order of P species concentrations was HCl-P>OP>NaOH-P. Both IP and HCl-P were highly positively correlated with total P in the upland soil, the WLFZ soil and the sediment. However, only in the sediment, NaOH-P was positively correlated with total P and OP. All P species in the upland soil demonstrated greater spatial heterogeneity than those in the WLFZ soil and the sediment. Redundancy analysis revealed that the main variables explaining the variance in P species concentrations were Al in the upland soil and pH in the sediment
