It is shown that there are some states, which are entangled but do not violate Bell inequality in this system. Moreover, the relations of violations of Bell inequality, Cauchy-Schwarz inequality, and entanglement are discussed in detail.展开更多

This paper focuses on litological-facies features based on the analysis of organic remains (stromatolites, microphitolites and microfossils), in order to better precise the age and environmental deposit conditions of the Baikal Group. The results are used to draw a correlation between all the Precambrian of deposits of the South of East Siberia. The stratigraphy of the Baikal Group is then compared to the geodynamic evolution of this region, characterized by the break-up of the supercontinent Rodinia and subsequent opening of the Paleo-Asian Ocean. Stratigraphic analogs to the Baikal Group display in most areas deposits of various minerals (complex ores, phosphoresces, bauxites etc. have been dated of the same age), so the present study would also provides an economic interest.展开更多

The study was conducted in the municipality of Paragominas Messoregiao located in the northeast of Para. The basic data used in the economic evaluation of production of planting parica (costs and revenues) were derived from primary source through raising production cost of parica with farmers from the municipality, analyzing the period of production horizon of seven years. The discount rate chosen for economic evaluation was 10% per year. NPV (net present value) calculation IRR (internal rate of return), BCR (benefit-cost ratio) and EP (break-even point). To check the economic feasibility of producing parica the following criteria were used for economic analysis. The results for NPV, IRR and BC ratio were respectively of $495,970, 28.83% and 2.43. For EP (break-even point) the value of 41.08% was found, which demonstrates the minimum amount of production, so that revenue equals costs. Based on the results obtained, it was found that the reforestation model with parica proposed in this paper presents economically viable for deployment.展开更多

An absolute gravimeter was used for gravity observation. The strongest precision requirements concern tidal gravity prediction. It is the reason why we investigated tidal effect by LCR (LaCoste & Romberg) gravimeter from 1996 to 1997 at the same station. We use tested tidal model for correction of gravity change. The linear component of gravity variations corresponds to changes in the elevation of the site. The correlation coefficient is close to the normal value of the vertical gradient of gravity. At this site, coseismic gravity variations at the time of the Kultuk earthquake (August 27, 2008, Mw = 6.5) were caused by a combined effect of the change of the site's elevation and deformation of the crust. Our estimations of the coseismic effects are consistent with results obtained by modeling based on the available seismic data.展开更多

The illegibility of these alphabets for Western people, along with the ancient prestige of at least Hebrew and Greek, fostered the illusion of temporal continuity and provided legitimacy to their atomization projects. Odysseas Elytis (1911-1996), Nobel Prize for Literature winner in 1979 and the last national poet of Greece, blends this old tendency in Greek culture and the broader claim of modern European poets for the essential autonomy of art and literature. His efforts to reinforce the walls separating Greece from Latin-Western culture by reinforcing the illegibility of both Greek and poetic idioms, aim at constructing a more essential Greece, founded on aesthetics, language, and writing instead of politics, institutions, or geographic borders. In this paper engaging mainly in the fields of literary and postcolonial studies, the author intends to analyze the mechanisms by which language, writing, or literature can be used to (re)cipher once again the already exclusive concept of nation, and thus to undermine every possibility of deciphering and translatability. He concludes that in “conceptually colonized” nations such as Greece, this process implies and anticolonial movement still caught nevertheless in a colonial discursivity.展开更多

Ten stations were selected based on altitudinal gradient, inside each station, identified flora has been conducted and a soil sample was taken from. A floristic inventory was carried out from all stations characterizing habitat of our studied taxon which is Rhamnus alaternus L. The authors established a list of plants represented by 94 species, distributed in 46 botanical families that are dominated by Asteraceae. The biological spectrum of these species reveals the dominance of hemicryptophytes and therophytes. The biogeographical element which predominates the vegetation is the Mediterranean-type. Statistical processing PCA (principal component analysis) from the pedological analysis of the examined stations reveals the formation of three groups defining a set of station that are marked by the presence of some components of the soil. Data processing obtained by FCA (factorial correspondence analysis) and the ascending hierarchical classification had underscored the existence of two groups of strata according to the soil substrate.展开更多

文摘Violations of Bell inequality, Cauchy-Schwarz inequality and entanglement in a two-mode three-level atomic system are investigated. It is shown that there are some states, which are entangled but do not violate Bell inequality in this system. Moreover, the relations of violations of Bell inequality, Cauchy-Schwarz inequality, and entanglement are discussed in detail.
