Multi-scale simulation of capillary pores and gel pores in Portland cement paste

The microstructures of Portland cement paste (water to cement ratio is 0.4, curing time is from 1 day to 28 days) are simulated based on the numerical cement hydration model, HUMOSTRUC3D (van Breugel, 1991; Koenders, 1997; Ye, 2003). The nanostructures of inner and outer C-S-H are simulated by the packing of monosized (5 nm) spheres. The pore structures (capillary pores and gel pores) of Portland cement paste are established by upgrading the simulated nanostructures of C-S-H to the simulated microstructures of Portland cement paste. The pore size distribution of Portland cement paste is simulated by using the image segmentation method (Shapiro and Stockman, 2001) to analyse the simulated pore structures of Portland cement paste. The simulation results indicate that the pore size distribution of the simulated capillary pores of Portland cement paste at the age of 1 day to 28 days is in a good agreement with the pore size distribution determined by scanning electron microscopy (SEM). The pore size distribution of the simulated gel pores of Portland cement paste (interlayer gel pores of outer C-S-H and gel pores of inner C-S-H are not included) is validated by the pore size distribution obtained by mercury intrusion porosimetry (MIP). The pores with pore size of 20 nm to 100 nm occupy very small volume fraction in the simulated Portland cement paste at each curing time (0.69% to 1.38%). This is consistent with the experimental results obtained by nuclear magnetic resonance (NMR)

Intermediate Biblical Greek Reader: Galatians and Related Texts

After completing basic biblical Greek, students are often eager to continue to learn and strengthen their skills of translation and interpretation. This intermediate graded reader is designed to meet those needs. The reader is “intermediate” in the sense that it presumes the user will have already learned the basics of Greek grammar and syntax and has memorized Greek vocabulary words that appear frequently in the New Testament. The reader is “graded” in the sense that it moves from simpler translation work (Galatians) towards more advanced readings from the book of James, the Septuagint, and from one of the Church Fathers. In each reading lesson, the Greek text is given, followed by supplemental notes that offer help with vocabulary, challenging word forms, and syntax. Discussion questions are also included to foster group conversation and engagement. There are many good Greek readers in existence, but this reader differs from most others in a few important ways. Most readers offer text selections from different parts of the Bible, but in this reader the user works through one entire book (Galatians). All subsequent lessons, then, build off of this interaction with Galatians through short readings that are in some way related to Galatians. The Septuagint passages in the reader offer some broader context for texts that Paul quotes explicitly from the Septuagint. The Patristic reading from John Chrysystom comes from one of his homilies on Galatians. This approach to a Greek reader allows for both variety and coherence in the learning process. Other unique features within this intermediate Greek reader include a set of word studies for important Greek words in Galatians, a discussion of the basics of textual criticism, and a brief glossary of syntax and key concepts in biblical Greek. This reader is a collaborative project that developed out of an advanced Greek course at Portland Seminary (2017-2018). The following students contributed equally to the content of the textbook. Alexander Finkelson (MATS, Portland Seminary, 2018) Bryn Pliska Girard (MATS, Portland Seminary, 2018) Charles E. R. Jesch (MDIV, Portland Seminary, current student) Paul C.

Moving to the Future

Last fall, Linfield College purchased 20 acres in northeast Portland for a new nursing campus. When Linfield moves to its new facility in May 2020, it will mark a new chapter in nursing at Linfield, and the end of an era for the Linfield-Good Samaritan School of Nursing’s northwest Portland location, its home since 1982

The origins of American industrial success: Evidence from the US portland cement industry

The contributions of innovations, factor endowments and institutions to American industrialization are examined through analysing the rise of the American portland cement industry. Minerals abundance contributed in multiple ways to the spectacular rise of the industry from the 1890s. However, the results of a structural econometric analysis of entry suggests geological surveys, institutions highlighted by David and Wright, played a contributing rather than critical role in the American portland cement industry overcoming incumbent European portland cement and American natural cement producers.American Economic History; Empirical Industrial Organization; Portland Cement
