Different landmarks were placed to gauge the spatial memory of C. sphinx. We changed the number of landmarks every day with 0 landmarks again on the fifth day （from 0, 2, 4, 8 to 0）. Individuals from the control group were exposed to the identical artificial foraging environment, but without landmarks. The results indicated that there was significant correlation between the time of the first foraging and the experimental days in both groups （Pearson Correlation： experimental group： r=-0.593, P〈0.01; control group： r=-0.581, P〈0.01）. There was no significant correlation between the success rates of foraging and the experimental days in experimental groups （Pearson Correlation： r=0.177, P〉0.05）, but there was significant correlation between the success rates of foraging and the experimental days in the control groups （Pearson Correlation： r=0.445, P〈0.05）. There was no significant difference for the first foraging time between experimental and control groups （GLM： F0.05,1=4.703, P〉0.05）; also, there was no significant difference in success rates of foraging between these two groups （GLM： F0.05,1=0.849,P〉0.05）. The results of our experiment suggest that spatial memory in C. sphinx was formed gradually and that the placed landmarks appeared to have no discernable effects on the memory of the foraging space.展开更多

It has survived for more than 50 million years, is a real ＂living fossil＂. Priapulid was extremely prosperous in the Cambrian period. It is a small phylum in the modern ocean; only 18 current types have been described, In the Cambrian life, priapulid is one of the most important living organisms in the sea of Cambrian. The abundance of priapulid is generally much higher than that of other animals, or only after the arthropod, and its differentiation is only after the arthropod and the porous sponge. The priapulid of the Early Cambrian in Chengjiang fossil Lagerstatte has 16 basic groups of seven genera.展开更多

The lining of the avenue was erased. Centuries over centuries this avenue has been buried with its statues under about 2 m of silt and sand, and urban development covered it with housing, asphaltic streets, and other structures, obscuring its route and interrupting this dramatic connection. This paper focuses on the discovery of some of these Sphinx statuses and remains at a suggested part of the avenue using both near-surface magnetic and shallow seismic refraction methods. A gradiometer survey was conducted in an area that amounted 576 m2 as (48 m?× 12 m) to measure the vertical magnetic gradient with a high resolution instrument with 0.25 m sampling interval. A superior detection was accomplished by using the analytic signal and Euler deconvolution techniques. The shallow seismic refraction survey was done in the same area to illustrate the lithology of layers material with 1 m interval;both P and S waves were measured to calculate the geotechnical properties of the area to sustain the sketch of structures’ boundaries. We have lucratively detected six main structures;they can be the pedestal of these Ram-headed Sphinx statues. Mining a small part of the study area has proven the reliability of, both the magnetic and shallow seismic refraction discoveries, and the shallowness and composition of the detected features.展开更多

The Russian thinkers and writers discussing the nature of Russia often return to the motif of Sphinx. Opposed to its ancient Greek archetype-counterpart, ＂the Russian Sphinx＂ does not have to resort to intricate questions--he is a riddle himself. As I show and explain, the livelihood and dissemination of the Russia-Sphinx motif in the homeland of Dostoyevski are not incidental. This motif is a synthetic medium of many archetypal contents, which accurately articulate a set of traditional intuitions and imaginations held by the Russians and concerning the alleged essence, nature, or depth of ＂Russianness＂. To conclude, I demonstrate the need to make the people comprehending Russia in a similar way aware that the accompanying, the particular--in its basic framework a priori assumed by them--image of the Russian reality is de facto a correlate of their subjective cognitive intention.展开更多
