AbstractThe main body of the site of Huahaizi No. 3 in Qinghe (Qinggil) County, Xinjiang, is a stone cairn surrounded by a stone circle with cross-shaped spokes. Around it, stone circles and stone cairns for sacrifices are located. In addition to two deer stones, shield-shaped stones, a simple wooden frame structure and fragments of human bones and sheep teeth used as sacrifices were found. The scientific data and the style of the deer stones show that this site was in use from around the 9th century BCE. The archaeological remains and artifacts show that this site and similar remains are for sacrificial activities, which might be related to the worship of sun, the moon and other celestial bodies or phenomena. The Sandaohaizi Site and similar remains found nearby as well as at the Arzhan kurgans in Tuva, Southern Siberia would have been left by the same people; Sandaohaizi was the summer ritual center of this early nomadic society and Arzhan was its royal necropolis.

Introduction: Based on the comparative and analytical studies on the research work conducted on the damage mechanism and mechanical property of the composite structure after exposure to fire, the research method and the research achievements are summarized and reviewed. Results and Conclusion: The achievements are mainly obtained from the studies on the beam (floor-slab) component, beam-column joints and the frame structure by the means of the axial compression static experiment or quasi static experiment in the past. Finally, some issues that still need to be studied are also discussed from three prospects.

This thesis investigated the mechanical property of the semi-rigid steel beam-column connection and its influence upon the propery of the framework; grounded on several foreign common mathematical models on the moment-rotation relationship of semi-rigid connection, and on the basis of exponent function model, it derived the ultimate bearing capacity (Mμ) and initial connection stiffness (Rki) which act as controlling function in the formula. Also, it imitated the typical connection of top-seat-angle with double web-angle, ensured its moment-rotation curve, and provided a reference for the analysis of the ultimate bearing capacity in the second-order effect of light steel frame structure.

The objective of this work is to analyze and optimize a bus frame structure using Finite Element Method in dynamic conditions. The bus body geometry was obtained directly from the three-dimensional Computer-Aided Design files. The optimization was conducted to determine the minimum weight of the bus frame structure without violating the specified natural frequency constraints. The design variable is the thickness of the bus body frame. In present study, Adaptive Single Objective method was chosen as an optimizer method. The results show that the structural weight of the bus frame can be reduced about 8% without changing its dynamic characteristic.

Good Improvement

4340 Ni-Cr-Mo alloy steel is widely used due to its good combination of strength and toughness. The mechanical property of 4340 steel can be improved by various thermal treatments. The influence of thermomechanical treatment (TMT) has been studied in a low carbon Ni-Cr-Mo steel having chemical composition closed to 4340 steel. TMT of 4340 steel is rarely examined up to now. In this study we obtain good improvement on the mechanical property of 4340 steel by TMT. The mechanism is explained in terms of TEM microstructures4340 (0.39C-1.81Ni-0.93Cr-0.26Mo) steel was austenitized at 950°C for 30 minutes. The TMTed specimen (T) was obtained by forging the specimen continuously as the temperature of the specimen was decreasing from 950°C to 600°C followed by oil quenching to room temperature. The thickness reduction ratio by forging is 40%. The conventional specimen (C) was obtained by quenching the specimen directly into room temperature oil after austenitized at 950°C for 30 minutes. All quenched specimens (T and C) were then tempered at 450, 500, 550, 600 or 650°C for four hours respectively.

Sperm of decapod crustaceans are formed by a round or cup-shaped body, a complex acrosome and one a few appendages emerging from the main body. Although this sperm does not have motility, it has some components of the cytoskeleton like microtubules, which are found inside the appendages. Actin filaments have been found in the spike of penaeidae sperms. The actual participation of the crustacean decapod sperm cytoskeleton during fertilization is not well understood. Actin is supposed to play an active role in drawing the penaeidae shrimp sperm closer to the egg after bending of the spike. The present study was aimed at the localization of actin filaments in sperm of the Robinson Crusoe island lobster, Jasus frontalis and in the crayfish Orconectes propincus, by fluorescent probes and low voltage scanning electron microscopy.
