Improving urban land use efficiency is a feasible way to realize sustainable development and alleviate pressure on the city. The main purpose of this article measure Yangtze River Economic Belt, explore its evolutionary trends influencing factors, so as provide references for policy formulation promote efficient development. Therefore, we calculated value in economic belt from 2004 2019, based ...

in this article, the elasto-plastic analysis of thick walled fg tanks subjected to internal pressure is elaborated. today, thick walled tanks containing liquids with high pressure are used in the chemical industries. the high internal pressure causes part of the thickness of reservoir to yield; therefore, we need the elasto-plastic analysis. in this study, elasto-plastic behavior of fg cylindri...

Aucuparia is an important slow growth forest tree with medicinal, industrial and ornamental uses which is applied for reforestation in high altitude of mountain lands. This species has been endangered at northern forests of Iran; therefore micropropagation of adult trees by bud culture may help to reforestation. The best sterilizing treatment was the buds washing with HgCl2% 0.1 solution for 7 ...

Circumstellar disks have long been regarded as windows into planetary systems. The advent of high sensitivity, high resolution imaging in the submillimetre where both the solid and gas components of disks can be detected opens up new possibilities for understanding the dynamical histories of these systems and therefore, a better ability to place our own solar system, which hosts a highly evolve...

sangan magnetite skarn mine is located 300 km southeast of mashhad, along the eastern part of khaf-drouneh volcanic-plutonic belt. granitoids from three areas within the sangan mine a, c-north and dardvay were studied. within the study area, three intrusive rocks including biotite-hornblende monzonite porphyry, biotite syenite and syenogranite were recognized. based on field cross cutting, abse...

The auditory fields in the cortex of the guinea pig were investigated with microelectrode mapping techniques. Pure tones of varying frequencies and amplitudes were used as acoustic stimuli. Mainly, multiunit activity was recorded. A large tonotopic area is found in the anterior half of the auditory cortex. This area is named the anterior field (field A). Frequency tuning curves of multiunits in...

In the present study, the 3-dimensional artistic relief designs on the leather belt used to create CNC tool path and the parameters were investigated in the production of hot pressing molds. The 3-dimensional relief patterns obtained with the help of belt pressure molds consist of marks pressed along the belt with the hot press. These intricate patterns create the varieties in the world of wear...

Intravenous tranexamic acid (TXA) has been identified to be effective in total knee arthroplasty (TKA), but the effect of topical application is still unclear. Therefore, the authors conducted a meta-analysis to assess the effect of topical TXA in TKA. Twelve trials with a total of 1179 knees were included. The results revealed that the application of topical TXA in TKA significantly reduced to...

BACKGROUND Cataract is one of the most common surgical procedures in the elderly. In most cases, the elderly have cardiac ischemia or chronic coronary diseases, which would lead to more ischemic events during general anesthesia. Therefore, surgeons and anesthetists prefer regional aesthesia to the general one owing to its more advantages and less complications. OBJECTIVES Therefore, this stud...
