statistical comparison of the baseline mechanical properties of nbg-18 and pcea graphite

Effect of specimen size and grain orientation on the

2015/7/1We present here a comparison of the measured baseline mechanical and physical properties of with grain (WG) and against grain (AG) non-ASTM size NBG-18 graphite. The objectives of the experiments were twofold: (1) assess the variation in properties with grain orientation; (2) establish a correlation between specimen tensile strength and size.

Characterisation of the spatial variability of material

2018/12/1This low correlation length values mean that spatial variations of mechanical properties can be expected across a billet of NBG-18. An interesting consequence might be the occurrence of "odd" or "outlier" data point in Arrhenius plots for graphite NBG-18 oxidation by air, as reported independently by Jo Jo Lee [ 32 ], Hans-Kemens Hinssen [ 33 ] and by S H Chi [ 34 ].

Pupils will be placed in one of 10 ability bands – or deciles – based on exams on the Three Rs, so that schools and parents can see whether they are high, average or low performers based on a national ranking.

In a comparison of calculated FT values with measured levels, group 3 had an R-2 = 0.93; however, samples with FT values less than 50 pg/mL had a poorer correlation (R-2 = 0.45). Calculated FT values may accurately reflect and be substituted in the clinical setting for gold-standard values when levels are more than 50 pg/mL.

Graphite Technology Development Plan: W. Windes T.

Variability within-billet, intra-billets, and lot-to-lot of the graphite must be accounted for in a statistical manner because of its influence on material properties. This variability must also be characterized to enable credible designs and to support the ongoing development of the probabilistic American Society of Mechanical Engineers (ASME) graphite design methodology.

Sustainability behind sustentability

Indicators are statistics and as such they are often produced by processing statistical data in order to demonstrate the current state or the trend of a phenomenon. Thus, in comparison to environmental statistics, which are based on existing or new data, indicators are based on the information that is needed for decisions that must be made and is a combination of one or more variables.

Statistical Comparison of the Baseline Mechanical

This report is a preliminary comparison between the two grades of graphite that were initially favored in the two main VHTR designs. NBG-18, a medium-grain pitch coke graphite from SGL formed via vibration molding, was the favored structural material in the pebble-bed configuration, while PCEA, a smaller grain, petroleum coke, extruded graphite from GrafTech was favored for the prismatic

In this retrospective study, patients with noninfectious uveitis younger than 18 years of age who were treated with adalimumab for more than 12 months were included. The rate of complete suppression and the relapse in anterior chamber inflammation following the initiation of adalimumab therapy were evaluated using anterior chamber cell score and laser flare photometry (LFP) values, if available.
