The Gejiu region in southeast Yunnan Province was an important metal and ore production area China as early the Han Dynasty (202 b.c.–a.d. 220). Past archaeological investigations this discovered ancient smelting site. Large numbers of smelting-related relics including lead discs, copper ingots, wastes were also excavated from Heimajing cemetery site nearby. These discoveries suggest that burial occupants probably involved mining, smelting, industry. An archaeometallurgical analysis...

‘Open access’ is an important part of the open science movement and a significant change to existing model academic publication. Based on data from large-scale survey Chinese scientists, this paper describes their awareness of, attitudes involvement in access.

The transverse rectus abdominis myocutaneous (TRAM) flap has become the gold standard for autologous breast reconstruction in last decade. deep inferior epigastric perforator (DIEP) is a refinement of conventional flap, which based on anatomic studies abdominal wall. These authors have performed transparent morphologic study abdominothoracic wall, order to visualize vessel architecture and relationships. methodology specimen processing, findings, modifications surgical incisions are...

Soft tissue defects of the forefoot represent a challenging surgical modality to reconstructive microsurgeons. This study describes anatomical basis and design perforator‐based intermediate dorsal pedal neurocutaneous vascular flap. Thirty fresh human lower limb specimens were injected with red latex used for dissection neural anatomy foot. The direction distribution cutaneous nerve third artery plantar arch, along nutrient vessels, mapped. A simulated flap elevation procedure was performed...

The following contents observed under surgical magnifier: ①The origin, courses, branches distribution arch. ②The anastomoses among rete arteriosum dorsale pedis. Mimic...

Combining IPFS, SHA256 algorithm and digital certificate technology, this paper proposes a four-level, three-module public-tested intellectual property trusted management system. The system first extracts the information process on basis of sorting out agent-oriented business process. Then establishes integration platform model designs it from aspects function architecture security guarantee. Finally, PMF software integrated development environment is selected to implement three main...
