This paper describes our development of a rapid on-line column/ID-ICP-MS technique for the analysis of plutonium (Pu) in environmental samples using an UTEVA extraction chromatograph resin (UTEVA resin) column. It took only 40 min to separate and measure Pu in the sample solution, including the time for conditioning the resin column for the next analysis. In our method, Pu in a 3 M nitric acid ...
Recently, the use of headed bars as mechanical anchorage in reinforced concrete beam-column joints has increased rapidly. This type is used for T-shaped beam and exterior column at middle floors L- rooftops buildings. However, few experimental data are available regarding capacity embedded L-shaped joints. Nine pullout tests conducted to investigate Parameters affecting capacity, such diameter,...
The organization of neuronal wiring into layers and columns is a common feature of both vertebrate and invertebrate brains. In the Drosophila visual system, each R7 photoreceptor axon projects within a single column to a specific layer of the optic lobe. We refer to the restriction of terminals to single columns as tiling. In a genetic screen based on an R7-dependent behavior, we identified the...
با توجه به پرزینگی نخ بر روی استحکام نخ، جذب نامنظم رنگ، زیردست و عایق حرارتی بودن پارچه ها، بوجود آمدن پرز در سطح پارچه و فرآیندهای بعد از ریسندگی و اینکه در اکثر موارد، پرزینگی نخ خصوصیتی منفی و مشکل ساز می باشد. بررسی این فاکتور برای کنترل آن، دارای اهمیت خاص می باشد. پارامترهای بسیاری در سیستم ریسندگی رینگ (سرعت دوک، جنس روکش علتک تولید و...) بر روی پرزینگی نخ موثر می باشند که دانستن چگونگی...
In this paper we introduce the cone bounded linear mapping and demonstrate a proof to show that the cone norm is continuous. Among other things, we prove the open mapping theorem and the closed graph theorem in TVS-cone normed spaces. We also show that under some restrictions on the cone, two cone norms are equivalent if and only if the topologies induced by them are the same. In the sequel, we...
We demonstrate a method to simulate pulse profile of the emission accretion columns in neutron star. Given set parameters that characterize star, e.g., mass and radius, positions shapes columns, can be calculated compared with real data. Some characteristics phase diagrams are shown considering an column form cone trunk also cylinder. Furthermore, our first approach we develop combination betwe...
The spinnability of a spinning solution using DMSO as the solvent was investigated for dry-jet wet spinning of PAN precursor fiber. Among many variables responsible for spinnability, the coagulating conditions, the air gap length, the nonsolvent content in spinning solution, and the spinning temperature have been viewed as the key factors, and they were investigated in this study. It was found ...
Positrons in the energy range of 3-30 MeV, produced by x rays emitted by betatron motion in a plasma wiggler of 28.5 GeV electrons from the SLAC accelerator, have been measured. The extremely high-strength plasma wiggler is an ion column induced by the electron beam as it propagates through and ionizes dense lithium vapor. X rays in the range of 1-50 MeV in a forward cone angle of 0.1 mrad coll...
L. L. Cheng, A. G. Zepeda, C. Wu, R. G. Gonzalez, A. Bielecki, D. Cory MGH/Harvard Med School, Boston, MA, United States, MIT, Cambridge, MA, United States Synopsis. Applying high resolution magic angle spinning (HRMAS) NMR spectroscopy to investigate cellular metabolism of diseases has encouraged exploration of slow spinning methodologies to better preserve tissue pathology structures against ...
