Equilibrium phase relationships during solidification of Fe-O-C-X alloys (1972)

Analysis of the solidification process of alloys requires that the phase relationships at equilibrium be known. The problem is complex and difficult for commercial ferrous alloys because of the presence of iron, carbon, oxygen, a deoxidizer, manganese, sulphur, etc. This study develops the phase relationships in the iron-rich corner of four component systems and covers the Fe-O-C-Si and Fe-O-C-Al systems specifically. The equilibrium state is treated at 1 atm pressure. The effects of suppression of formation of CO and of segregation of elements between liquid and solid iron are then analyzed.

Abstract 12246: Significant Improvement In Atherosclerotic Risk Factors From Intensive Cardiac Rehabilitation Is Lost After Program Discontinuation (2021)

Introduction: Intensive Cardiac Rehabilitation [ICR: Dr. Dean Ornish Program] is proven to reduce risk factors associated with CVD by facilitating stress management education, plant-based nutrition, and structured exercise. The present study aimed to determine if ICR programs can show sustained improvement in high-risk (elderly and rural) populations. Hypothesis: We assessed the hypothesis that ICR participants would not show sustained atherosclerotic risk factor improvement in a 7-14-month timeframe after program completion. Methods: Participants (n=65, mean age 75 +/- 6.5 (56% Male)) with a prior diagnosis of stable angina pectoris, secondary to CVD, completed a nine-week ICR program. Patients’ biomarker data was tracked in the range of 7-14 months following program completion. Eight biomarkers were evaluated including LDL, HDL, and Hb-A1c. The analysis utilized either parametric or nonparametric paired tests, with an adjusted P -value of 0.00625 as eight variables were tested. Serum labs were drawn at least five months before program commencement and at most one week following program completion. BMI was recorded at a separate date, with the P- value set at 0.05. Results: The sample size was n=62. From baseline, patients’ LDL (11.8% decrease, 95% CI) and Hb-A1c (3.2% decrease, 95% CI) showed significant change ( P <0.00625) using the paired Wilcoxon signed-rank test. During the follow-up period, the same methods were applied to a smaller sample size (n=30). This resulted in a significant change ( P < 0.00625) for LDL (increased 13.4%) and HDL (increased 7.3%). With n=55, BMI showed significant change (3.9% decrease, 95% CI, P< 0.05) using the paired Wilcoxon signed-ranked test directly after program completion. In the follow-up period, n=36 and BMI showed significant change (1.5% increase, 95% CI, P < 0.05) with the same method. Conclusion: Patients with atherosclerotic coronary disease optimized on medical therapy prior to enrollment in the ICR still showed improvement in biomarker levels with rehabilitation. However, these programmatic benefits were lost in the subsequent months due to a lack of structured supervision. In conclusion, we suggest long-term maintenance of ICR protocols and structured supervision in high-risk populations.
Lectinochemical characterization of a GalNAc and multi‐Galβ1→4GlcNAc reactive lectin from <i>Wistaria sinensis</i> seeds (1999)

An agglutinin that has high affinity for GalNAcbeta1-->, was isolated from seeds of Wistaria sinensis by adsorption to immobilized mild acid-treated hog gastric mucin on Sepharose 4B matrix and elution with aqueous 0.2 M lactose. The binding property of this lectin was characterized by quantitative precipitin assay (QPA) and by inhibition of biotinylated lectin-glycan interaction. Of the 37 glycoforms tested by QPA, this agglutinin reacted best with a GalNAcbeta1-->4 containing glycoprotein (GP) [Tamm-Horsfall Sd(a+) GP]; a Galbeta1-->4GlcNAc containing GP (human blood group precursor glycoprotein from ovarian cyst fluid and asialo human alpha1-acid GP) and a GalNAcalpha1-->3GalNAc containing GP (asialo bird nest GP), but poorly or not at all with most sialic acid containing glycoproteins. Among the oligosaccharides tested, GalNAcalpha1-->3GalNAcbeta1-->3Galalpha1-->4Galbeta 1-->4Glc (Fp) was the most active ligand. It was as active as GalNAc and two to 11 times more active than Tn cluster mixtures, Galbeta1--> 3/4GlcNAc (I/II), GalNAcalpha1-->3(L-Fucalpha1-->2)Gal (Ah), Galbeta1-->4Glc (L), Galbeta1-->3GalNAc (T) and Galalpha1--> 3Galalpha-->methyl (B). Of the monosaccharides and their glycosides tested, p-nitrophenyl betaGalNAc was the best inhibitor; it was approximately 1.7 and 2.5 times more potent than its corresponding alpha anomer and GalNAc (or Fp), respectively. GalNAc was 53.3 times more active than Gal. From the present observations, it can be concluded that the Wistaria agglutinin (WSA) binds to the C-3, C-4 and C-6 positions of GalNAc and Gal residues; the N-acetyl group at C-2 enhances its binding dramatically. The combining site of WSA for GalNAc related ligands is most likely of a shallow type, able to recognize both alpha and beta anomers of GalNAc. Gal ligands must be Galbeta1-->3/4GlcNAc related, in which subterminal beta1-->3/4 GlcNAc contributes significantly to binding; hydrophobicity is important for binding of the beta anomer of Gal. The decreasing order of the affinity of WSA for mammalian structural carbohydrate units is Fp >/= multi-II > monomeric II >/= Tn, I and Ah >/= E and L > T > Gal.

Monitoring pH and solvent proticity with donor–acceptor-substituted biphenyls: a new approach towards highly sensitive and powerful fluorescent probes by tuning the molecular structure (2000)

The ability and structural requirements of 4-dimethylamino-4′-cyano-substituted biphenyls showing photoinduced intramolecular charge transfer (CT) to serve as hydrogen bond- or pH-sensitive fluorescent probes is investigated. The donor–acceptor (D–A) biphenyls I and II being planar in the CT excited state are most suitable as pH-sensitive fluorescent probes. The two compounds show analytically valuable features such as well-separated absorption and emission bands and signal changes spanning four orders of magnitude and can be employed in ratiometric, “self-calibrating”, and highly sensitive pH fluorosensing in the range 0<pH<4. Because of an enhanced charge separation in the excited state, the highly twisted D–A biphenyl III shows an increased proton sensitivity and can therefore be used to probe solvent proticity ia hydrogen bond formation. The molecular and electronic characteristics of the two types of probes are discussed for the different neutral and acidic alcoholic and/or aqueous solvent mixtures investigated.
Second harmonic generation in reverse proton exchanged Lithium Niobate waveguides (2001)

We investigate efficient second harmonic generation in reverse proton exchanged Lithium Niobate waveguides. In z-cut crystals, the resulting buried and surface guides support TM and TE polarizations, respectively, and are coupled through the d 31 nonlinear element. Numerically estimated conversion efficiencies in planar structures operating at 1.32microm reach 90% in 2cm or a normalized 14% microm/Wcm.
Theoretical Model of Lubrication Mechanism in the Thrust Slide-Bearing of Scroll Compressors (2008)

This study presents a theoretical model of the remarkably good lubrication characteristics of the thrust slide-bearings found in scroll compressors experimentally by Ishii et al. (2007). It has been suggested that the thrust plate undergoes elastic deformation due to axial loading. As a result of this deformation, a fluid wedge is believed to form at the periphery of the thrust plate. The fluid wedge angle between the sliding surfaces was calculated with a finite element method analysis and then used in the average Reynolds equation from Patir and Cheng (1978, 1979) to analyze the fluid lubrication on rough sliding surfaces. The plastic and elastic contacts between the orbiting and fixed thrust plates were analyzed using the solid contact theory from Greenwood and Williamson (1966). The derived theoretical model permitted the calculation of the oil film pressure, the solid contact force, the fluid frictional force, and the solid shearing drag force. These results were used, in turn, to determine the resultant friction coefficient at the thrust slide-bearing. Finally, it is shown that the predicted theoretical results agree well with the experimental lubrication test results of Ishii et al. (2007). The proposed theoretical development appears to model accurately the essential mechanism for the remarkably good mixed fluid-and-solid lubrication in a thrust slide-bearing.
Performance evaluation of a hybrid OBS/OCS network with QoS differentiation based on packet loss/delay requirements (2010)

This paper introduces and evaluates a hybrid OBS/OCS switch for Quality of Service (QoS) differentiation in next-generation all-optical transport networks. Depending on their QoS requirements, incoming IP packets are collected in delay-sensitive or loss-sensitive assembly queues. Once assembled, those departing delay or loss-sensitive bursts are sent to the destination over a parallel all-optical hybrid network, where a set of switch ports and wavelengths are dedicated to delay-sensitive OBS-like transmission based on Just Enough Time (JET), whereas the remainder are dedicated to loss-sensitive OCS-like transmission. The obtained results validate the differentiated transport services in the deployed reference network scenario. Moreover, they show that circuit set-up retries are mandatory in OCS to carry loss-sensitive traffic efficiently.
Part C: Directed Differentiation of Human Embryonic Stem Cells into Osteoblasts Cells (2007)

Human embryonic stem cells provide an ideal cell source for production of osteogenic cells due to their potential for expansion into therapeutically relevant numbers and the ability to differentiate into functional osteoblasts. The high demand for bone tissue repair necessitates the development of strategies to make functional bone. This chapter focuses on fundamental concepts in osteogenic differentiation and key protocols and techniques for inducing the differentiation of human ES cells into functional osteoblasts. Methods to determine osteogenic differentiation using osteocalcin or alkaline phosphatase immunocytochemistry are considered with emphasis on functional criteria such as production of mineralized bone nodules. The use von Kossa stain is discussed along with characterization of the mineralized matrix and ultrastructural studies with electron microscopy and FTIR. These techniques allow for proper characterization of osteogenic differentiation of human ES cells and permit this in vitro system to be used for studying mechanisms underpinning bone formation.
A stochastic approach to layered neural networks (2002)

We propose a stochastic framework to backpropagation. The network inputs are random variables, and thus a stochastic output is produced. The application range of this new approach goes from medical to financial problems. In this paper, a classification method for a two-group discriminant problem based on the interval algebra is proposed. This approach is limited to classification problems, and can not be directly extended to more than two groups.
Book Review - Yochai Benkler, the Wealth of Networks: How Social Production Transforms Markets and Freedom (2007)

Benkler argues that the West is engaged in an escalating culture war between the industrial information economy - a one-way, capital-intensive, and professionally-produced model that has held sway for 150 years - and the networked information economy (NIE) - many-to-many, low-capital, and cooperative model that has been emerging in the last 15 years. The NIE is built on the infrastructure of the internet and is characterized by characterized by (1) non-proprietary strategies, (2) rising non-market production, and (3) more effective, large-scale cooperative efforts, in other words, peer production of information, knowledge, and culture. These aspects challenge our economies and our polities, and hold significant promise for enhancing personal autonomy, however, Benkler, in writing what amounts to a manifesto for the internet, pays little attention to the way in which the NIE is vulnerable to technical capture in the same way the industrial information economy is vulnerable to capital capture, taking a wait-and-see approach to regulatory intervention. Still, Wealth of Networks is a comprehensive and readable survey of the arguments for a commons-based approach to the development of the NIE.

β‐galactosidase deficiency: Prolonged survival in three patients following early central nervous system deterioration (1978)

Three adult patients from two families have shown slowly progressive neurologic deterioration since the age of 3 years, associated with profound beta-galactosidase deficiency. Although affected individuals from the two different families differ in degree of intellectual deficit, facial coarseness and spondyloepiphyseal dysplasia, all lack visceromegaly and macular red spots. The diversity of phenotypic expression in these patients and others previously reported suggests the existence of composite genotypes (compound and double heterozygosity).

Environmental Conditions on Red Drupelet Incidence (2019)

Blackberry growers and packers have long realized the difficulty of preserving the black pigment of fruit when preparing for consumers. Red drupelet reversion is when fully mature black drupelets return to a red, burgundy color after harvest. Reversion occurs between the time of fruit harvest and consumer purchase, causing it to one of the most difficult postharvest problems to control. The relative humidity (RH) and temperature at time of harvest in addition to direction of rows in relation to the sun could all be variables that affect this reversion of color. In this experiment, two cultivars ‘Arapaho’ and ‘Natchez’ were picked at two different times (7:30 AM and 10:00 AM) from two different sides (east or west), and then immediately delivered into cold storage. The fruit was taken out of storage at one-week and two-week periods, where the number of red drupelets was then counted and recorded for each berry. Sensors that recorded relative humidity and temperature every 30 minutes were set up around the berry perimeter. We found that red drupelet reversion was lower in ‘Navaho’ compared to the ‘Arapaho’ cultivar. We also found that in warmer weather, fewer red drupelets are present on the berries and reversion was most common when RH was between 80% and 60%. Warmer weather and increased hours of sunlight also appear​ to decrease the incidence of reversion on west-facing rows. With additional studies and confirmation of our results, pickers may be able to use this information to harvest higher yield of desirable fruit.
Two-dimensional nonlinear optically induced photonic lattices in photorefractive crystals (2005)

We study theoretically arid generate experimentally two-dimensional nonlinear optically-induced photonic lattices with periodic phase modulation of different geometries in a photorefractive medium, including the periodicnonlinear waves with an internal energy flow or vortex lattices. We demonstrate that the light-induced periodically modulated nonlinear refractive index is highly anisotropic and nonlocal, and it depends on the orientation of a two-dimensional lattice relative to the crystal axis. We discuss stability of such optically-induced photonic two-dimensional structures and demonstrate experimentally their waveguiding properties.

Experimental and finite element investigation of residual stresses resulting from the thermal spray process (1995)

Experiments coupled with finite element modeling (FEM) have been used to examine residual stresses that arise in thermal spray samples. Substrate characteristics such as thickness, peak surface temperature, thermal gradients, and sample holder constraints have been examined in addition to the more commonly studied coating/substrate property mismatch effect. Elastic-plastic FEM considers temperature dependent thermal and mechanical properties during heating to the maximum surface temperature and subsequent cooling to ambient temperature, to calculate sample deformation, temperature distributions, and plastic strains in addition to residual stresses. Experiments utilize thermocouples located along the substrate radius and thickness to determine thermal gradients, and a specially designed sample holder to provide temperature control. Measured residual deformation at room temperature is compared to FEM results.
First Protection of a Wide-Rim Tetraamino Calix[4]arene in Opposite Positions (2007)

The importance of tetraamino calix[4]arenes as starting materials is distinctly increased by the first versatile protective group for opposite amino functions. Reaction with trityl chloride leads to the 1,3-dialkylated derivative easily isolated in 34% yield; after a first acylation of the remaining amino groups, the trityl residues can be removed by TFA to introduce a second acyl group.
