A Breakthrough in Pressure Generation by a Kawai-Type Multi-Anvil Apparatus with Tungsten Carbide Anvils Review

Takayuki Ishii, Zhaodong Liu, Tomoo Katsura

Engineering 2019, Volume 5, Issue 3,   Pages 434-440 doi: 10.1016/j.eng.2019.01.013

Abstract:

Expansion of the pressure range of Kawai-type multi-anvil presses (KMAPs) with tungsten carbide (WC) anvils is called for, especially in the field of Earth science. However, no significant progress in pressure generation has been made for 40 years. Our recent studies have expanded the pressure generation of a KMAP with WC anvils to 65 GPa, which is the world record for high-pressure generation in this device and is more than 2.5 times higher than conventional pressure generation. We have also successfully generated pressures of about 50 GPa at high temperatures. This work reviews our recently developed technology for high-pressure generation. High-pressure generation at room temperature and at high temperature was attained by integration of the following techniques: ① a precisely aligned guide-block system, ② a high degree of hardness of the second-stage anvils, ③ tapering of the second-stage anvil faces, ④ a high-pressure cell consisting of materials with a high bulk modulus, and ⑤ high thermal insulation of the furnace. Our high-pressure technology will facilitate investigation of the phase stability and physical properties of materials under the conditions of the upper part of the lower mantle, and will permit the synthesis and characterization of novel materials.

Effect of size on biaxial flexural strength for cement-based materials by using a triangular plate method

Hakan T TURKER

Frontiers of Structural and Civil Engineering 2022, Volume 16, Issue 8,   Pages 1017-1028 doi: 10.1007/s11709-022-0871-8

Abstract: The effect of size on the biaxial flexural strength (BFS) of Portland cement mortar was investigated by using the recently proposed triangular plate method (TPM). An experimental program was conceived to study the size effect by keeping a constant water-cement ratio of 0.485, cement-sand ratio of 1:2.75, and using unreinforced triangular mortar plates of five different thicknesses and seven different side lengths. The BFS of the produced specimens was tested, and variations of BFS depending on specimen thickness and side length were determined. The results indicated that increases in triangular plate specimen side length and specimen thickness led to a decrease in the BFS of Portland cement mortar. The effect of specimen length increase on BFS was more significant than on the effect of the specimen thickness. The variations in specimens’ thickness indicated a deterministic Type I size effect, while the variations in specimens’ length showed an energetic-statistical Type I size effect.

Diagnosis and therapy of lacrimal system diseases by micro lacrimal endoscope

Nan XIANG, Weikun HU, Jing YUAN, Guigang LI, Haixia LIU

Frontiers of Medicine 2009, Volume 3, Issue 1,   Pages 113-117 doi: 10.1007/s11684-009-0001-1

Abstract: The lacrimal endoscope is applied to the diagnosis and therapy of the disorders of the lacrimal system in combination with laser or micro drills under orthophoria. The changes of mucous membranes, the characteristics of pathological changes and the predilection sites of lacrimal system diseases were initially approached. One hundred and forty six pairs of eyes of 128 patients with lacrimal system disease were observed by the lacrimal endoscope in the Ophthalmology Department of Tongji Hospital from June 2006 to March 2007. The dynamic changes in mucous membranes, lesion sites, secreted substances and formation of membrane could be observed under orthophoria. Combined with laser or micro drill, the endoscope was applied to the therapy of lacrimal system disorders and the difference before and after the treatment was observed. Results are as follows: (1) The examination and therapy using the lacrimal endoscope were completed under topical anesthesia in 122 patients, and 6 patients of neonatorum dacryocystitis were examined and treated under general anaesthesia. All patients reported painless. (2) Sharp images of the lacrimal system were obtained by the endoscope. Normal lacrimal mucosal membrane was smooth and light pink, expanded and unobstructed during irrigation. In chronic dacryocystitis patients, the inhomogeneous colour of mucosal membranes was red and white, with different degrees of fibrotic membranes at the superior, middle and inferior parts of the nasolacrimal canals and secreted substances at sac could be observed. The lacrimal ducts could not be expanded and obstructed during irrigation. The patients with lacrimal system obstruction had different extents of membrane formation, and stenosis or complete obstruction of the lacrimal duct could be observed, and the corresponding mucosal membrane was not smooth which could not be expanded and obstructed during irrigation. (3) After the treatment by the endoscope combined with laser or micro drill, the major proliferation of the membrane disappeared and the lacrimal duct was unobstructed during irrigation. The cure rate and effective rate were 80.1% and 93.1%, respectively. The lacrimal endoscope is a new method in the diagnosis of lacrimal system diseases. Through a combination with laser or micro drill to carry out the therapy under orthophoria, it will bring a great change to the diagnosis and therapy of lacrimal system diseases.

Abstract: es (LVEAs) have many workpieces and intricate geometric structures, and the assembly process is rigid and labor-intensive, and has little balance. The assembly process cannot readily adapt to changes in assembly situations. To address these issues, a is proposed. Based on the requirements of , a colored Petri net (CPN) model is proposed to analyze the performance of the interaction and self-government of robots in . Also, an algorithm (AFPA) is presented to realize the assembly planning and of robots in the of LVEAs. Then an (AQGA) is developed to optimize the assembly process. Lastly, taking a two-pole circuit-breaker controller with leakage protection (TPCLP) as an assembly instance, comparative results show that the is cost-effective and flexible in LVEA assembly. The distribution of resources can also be optimized in the assembly. The assembly robots can interact dynamically with each other to accommodate changes that may occur in the LVEA assembly.
