摘要:An active cognitive lifestyle has been suggested to have a protective role in the long-term maintenance of cognition. Amongst healthy older adults, more managerial or supervisory experiences in midlife are linked to a slower hippocampal atrophy rate in late life. Yet whether simi...

摘要:A high-speed camera system is used to observe the diffusion flame of a Bunsen burner in linear motion. The resultant sequence of instantaneous motion pictures of the flame accelerating at 3.60 m/s2 is processed and used to study the change in the flame area and specifi...

摘要:Suppose that G is a finite group and H is a subgroup of G. We say that H is a BNA -subgroup of G if either H x = H or x ∈ < H, H x > for all x ∈ G. The BNA -subgroups of G are between normal and abnormal subgroups of G. We obtain some new characteriz...

摘要:The critical microcracks make durability of the concrete seriously weakened, and the water-cement ( w / c ) ratio plays a key role in the durability of concrete, acoustic emission (AE) rate “ a ” value is an effective parameter to evaluate the amount of critical microcracks ...

摘要:The insulin-like growth factor II/mannose 6-phosphate (IGF-II/M6P) receptor is a multifunctional single transmembrane glycoprotein. Recent studies have advanced our understanding of the structure, ligand-binding properties, and trafficking of the IGF-II/M6P receptor. This re...

摘要:A self-improved and debugged acousto-ultrasonic system was used to investigate the effect of water cement ratio (w/c ratio) on ultrasonic pulse wave propagation and find more accurate and effective evaluation parameters than the traditional ultrasonic pulse velocity (UPV). A...

摘要:Researchers have recently realized that the natural fractures in shale reservoirs are often cemented or sealed with various minerals. However, the influence of cement characteristics of natural fracture on fracturing network propagation is still not well understood. In this ...

摘要:Brittleness has been a prevalent descriptor in rock mass engineering and formation fracturing stimulation. Here a new definition of mechanical brittleness index as crack initiation stress level ( σ ci/ σ c) is proposed and verified with diorite, granite...
