Multimodal nanoparticles have been extensively studied for target-specific imaging and therapy of various diseases, including cancer. In this study, radiolabeled arginine-glycine-aspartic acid (RGD)–functionalized Er<sup>3+</sup>/Yb<sup>3+</sup> co-doped NaGdF<sub>4</sub> upconversion nanophosphors (UCNPs) were synthesized evaluated as a multimodal PET/MR/optical probe with tumor angiogenesis–specific targeting properties. <b>Methods:</b> A dimeric cyclic RGDyk ((cRGDyk)<sub>2</sub>) peptide...
Abstract Objectives The aim of this study is to examine the effect particulate autogenous tooth graft removed with organic matter and type I collagen addition on bone regeneration validate possibility useful allograft material for jaw defects. Material methods Autogenous maker (Korean Dental Solution® KOREA) made not including matter. We used developed grafts experiment. Cell adhesion test hemacytometer energy dispersive X-ray spectroscopy (Supra40 VP®, Carl Zeiss, Germany) analysis about...
The 2017 M5.4 Pohang, South Korea, earthquake damaged numerous buildings. Immediately after the main shock event, 1,880 professional engineers inspected buildings and assigned three damage grades ("Usable," "Restricted use," "Unusable"). We investigate factors influencing building damage. built year, number of stories, estimated peak ground acceleration are strongly related with frequency also prove that caused to is influenced by basin geometry, based on site parameters such as N value,...
The objectives of this study are to evaluate the variables that affect shear behavior unreinforced masonry (URM) walls and propose equation rocking toe crushing strength URM by regression analysis using test data including previous research. main axial stress, aspect ratio thickness walls. results show specimens governed failure modes. relationship is proportionate square root vertical stress linearly proportional. Shear cross sectional area not For tested, proposed strength/actual 0.95,...
The objective of this study is to propose and evaluate a neural network algorithm predict column shortening, including drying shrinkage creep in high-rise RC buildings. A proposed for the prediction shortening focuses on data processing training methods. validity examined through process based measuring In algorithm, polynomial fit line used as instead data. As result, it has been verified that can be estimated by using such more accurate than what predicted conventional method numerical models.
Laser welding has the advantage of high speed and provides low heat distortion. Thus, laser is a very attractive process for joining thin steel sheet surface treated sheet. And major item in market zinc coated steel. However, difficult because its boiling point. Compared with zinc, on other hand, aluminum weldability aluminized better than that Moreover material excellent resistance, thermal reflection corrosion resistance. The results full penetration will be described this paper. We...
This research describes effects of Si addition on microstructure and mechanical properties the Al-Cr based alloys prepared manufactured using gas atomization SPS (Spark Plasma Sintering) processes.The Al-Cr-Si bulks with high Cr content were produced successfully sintering process without crack obtained fully dense specimens close to nearly 100% T. D. (Theoretical Density).Microstructure as-atomized contents was composed multi-phases hard thermally stable such as Al 13 4 , AlCrSi, 8 5 3...
Structural fire-protective clothing must be effective at minimizing the thermal effects of fire. However, water remaining on outer shell might play an important role in conducting heat transfer, which causes skin burns a firefighter when he douses fire with through hose. Therefore, this research demonstrated difference transfer and humidity created by or lack under condition temperature (45 ± 1℃) external environment was higher than that skin. Two types multilayered systems, simulated real...
Magnesium alloys have gained increased attention in recent years as the structural materials, because of their attractive properties such good specific strength, excellent sound damping capability. However, to expand applications, a reliable joining process is absolutely necessary. In this study, CW fiber laser was used investigate lap weldability sand casting and wrought magnesium alloys. The effect defocused distance on examined, it found that spatters always generated at around focused...
Laser weldability of the aluminized steel for full penetration welding will be described in this paper. We focused on effect Al coating conditions weld strength. For these objectives, sheets that have various thickness and weight were prepared laser welding. And then, tensile-shear hardness test carried out. At same time, contents after analyzed their correlations with mechanical properties investigated. Besides, as removing partially layer, has been investigated according to position layer....
This study is related to the laser weldability of AZ31B magnesium alloy, an all-purpose wrought alloy with good strength and ductility. In general, classified into AZ31B-H24 AZ31B-O depending on temper designation. Thus, in this study, was investigated compared. CW Nd:YAG used produce bead butt joints. And effects welding conditions these joints were examined detail. As a result found have thinner oxide film smaller grain size compared AZ31B-O. Due such difference, welding, had more wide...
