Application and testing of a triple bubbler sensor in molten salts
Williams A.N.,Shigrekar A.,Galbreth G.G.,Sanders J. 한국원자력학회 2020 Nuclear Engineering and Technology Vol.52 No.7
A triple bubbler sensor was tested in LiCleKCl molten salt from 450 to 525 C in a transparent furnace to validate thermal-expansion corrections and provide additional molten salt data sets for calibration and validation of the sensor. In addition to these tests, a model was identified and further developed to accurately determine the density, surface tension, and depth from the measured bubble pressures. A unique feature of the model is that calibration constants can be estimated using independent depth measurements, which allow calibration and validation of the sensor in an electrorefiner where the salt density and surface tension are largely unknown. This model and approach were tested using the current and previous triple bubbler data sets, and results indicate that accuracies are as high as 0.03%, 4.6%, and 0.15% for density, surface tension, and depth, respectively
Quantifying and Localizing the Mitochondrial Proteome Across Five Tissues in A Mouse Population

<P>We have used SWATH mass spectrometry to quantify 3648 proteins across 76 proteomes collected from genetically diverse BXD mouse strains in two fractions (mitochondria and total cell) from five tissues: liver, quadriceps, heart, brain, and brown adipose (BAT). Across tissues, expression covariation between genes' proteins and transcripts-measured in the same individuals-broadly aligned. Covariation was however far stronger in certain subsets than others: only 8% of transcripts in the lowest expression and variance quintile covaried with their protein, in contrast to 65% of transcripts in the highest quintiles. Key functional differences among the 3648 genes were also observed across tissues, with electron transport chain (ETC) genes particularly investigated. ETC complex proteins covary and form strong gene networks according to tissue, but their equivalent transcripts do not. Certain physiological consequences, such as the depletion of ATP synthase in BAT, are thus obscured in transcript data. Lastly, we compared the quantitative proteomic measurements between the total cell and mitochondrial fractions for the five tissues. The resulting enrichment score highlighted several hundred proteins which were strongly enriched in mitochondria, which included several dozen proteins were not reported in literature to be mitochondrially localized. Four of these candidates were selected for biochemical validation, where we found MTAP, SOAT2, and IMPDH2 to be localized inside the mitochondria, whereas ABCC6 was in the mitochondria-associated membrane. These findings demonstrate the synergies of a multi-omics approach to study complex metabolic processes, and this provides a resource for further discovery and analysis of proteoforms, modified proteins, and protein localization.</P>

Synergetic effects of blended cathode active materials: Simulation and Experiment
( Williams Agyei Appiah ),박주남,변승우,유명현,이용민 한국공업화학회 2017 한국공업화학회 연구논문 초록집 Vol.2017 No.1
In the quest to achieve a higher capacity electrode materials for lithium ion batteries, different active materials for both cathode and anode are being studied. However, the available electrode materials which have been discovered have both good and bad sides. Hence, the electrochemical characteristics of Li-ion cells made of blended cathode material composed of LiMn2O4 and LiNi0.6Co0.2Mn0.2O2 and an artificial graphite anode are being studied via both experiments and simulation. The cycle performance of the two pure cell chemistries we modelled by considering Mn2+ dissolution in the cathode and solid electrolyte interphase information in the anode. By fitting our model predictions to the experimental data, the percentage of each contributing factor to the total capacity fade was determined. Ragone plots were used to study the correlation between the energy density and average specific power of the two pure chemistries and their blends.
Exact calculation of natural frequencies of repetitive structures
Williams, F.W.,Kennedy, D.,Wu, Gaofeng,Zhou, Jianqing Techno-Press 1996 Structural Engineering and Mechanics, An Int'l Jou Vol.4 No.5
Finite element stiffness matrix methods are presented for finding natural frequencies (or buckling loads) and modes of repetitive structures. The usual approximate finite element formulations are included, but more relevantly they also permit the use of 'exact finite elements', which account for distributed mass exactly by solving appropriate differential equations. A transcendental eigenvalue problem results, for which all the natural frequencies are found with certainty. The calculations are performed for a single repeating portion of a rotationally or linearly (in one, two or three directions) repetitive structure. The emphasis is on rotational periodicity, for which principal advantages include: any repeating portions can be connected together, not just adjacent ones; nodes can lie on, and members along, the axis of rotational periodicity; complex arithmetic is used for brevity of presentation and speed of computation; two types of rotationally periodic substructures can be used in a multi-level manner; multi-level non-periodic substructuring is permitted within the repeating portions of parent rotationally periodic structures or substructures and; all the substructuring is exact, i.e., the same answers are obtained whether or not substructuring is used. Numerical results are given for a rotationally periodic structure by using exact finite elements and two levels of rotationally periodic substructures. The solution time is about 500 times faster than if none of the rotational periodicity had been used. The solution time would have been about ten times faster still if the software used had included all the substructuring features presented.
치병과 구원 : 인간욕구의 제 차원 The Dimensions of Human Need
Williams, Daniel D. 연세대학교 신과대학 1961 신학논단 Vol.6 No.-
심신의 병을 치료한다는 것이 영혼 구원에는 어떠한 관계를 가지는가? 이 질문은 현금 교회가 "영혼치료"를 할 수 있다는 새로운 경향으로 우리 앞에 제기되었다. 현대 심리학적 지식은 인간 이해와 질병 취급에 있어서 혁명적 세력이 되었다. 심리학의 영향력이 어찌나 큰지 그 때문에, 오늘날 신학교육에 있어서도 목회 분야에서는 비단 정신요법 문제에만 주의를 기울이는 것이 아니라, 군중 치료와 군중 세력 문제에 있어서 목회자와 신도의 관계를 분석하는방법에 까지 점차 주의를 기울이게 되었다. 프로이드에 의하면 시발된 이 운동은, 종교생활의 제국면에 영향을 주고 있는 인간문제를 취급하는 방법에 까지 파급되었다.

To quantify the capacity fade mechanism in lithium ion batteries composed of a spinel-based cathode and an artificial graphite, a comprehensive mathematical model describing the cycling performance of LiMn2O4/graphite lithium ion cell is developed in this work. The developed model is incorporated into the Newman’s Porous Composite Electrode framework (PCE) and implemented in the battery module of COMSOL Multiphysics. The proposed model is used to investigate the effects of variations in the ambient temperature and of voltage range of cycling on the capacity fade. The effect of changes in the volume fraction of cathode active material, resistance in the cell and state of charge are also studied.
