Corrosion Behavior of Hot Dip Galvanized Steel in Concrete Environment. (2006)

Concrete structures have played an important role in the improvement of the social matrix so far. Therefore, the deterioration of concrete structures at relatively early stages found during their use has become a serious social problem. The main causes are cracking, neutralization, corrosion of rebar, etc. Investigation for the prevention and protection against the deterioration of concrete structures has been done both from the viewpoints of economics and safety. In this study, we investigated and assessed the corrosion characteristics of galvanizing steel in concrete solutions to establish countermeasures for corrosion prevention of steel rebar. As a result, we obtained the results that zinc reacted with solutions containing chlorides of higher concentration and that the corrosion characteristics for zinc film containing aluminum decreased.

Near-Field Scanning Microwave Microscopy: An Emerging Research Tool for Nanoscale Metrology (2014)

On 29 December 1959 at the annual meeting of the American Physical Society, Richard Feynman gave a lecture at the California Institute of Technology titled "There Is Plenty of Room at the Bottom: An Invitation to Enter a New Field of Physics." This memorable lecture has since become very famous as it predicted and envisioned the current era of nanoscience and nanotechnology. The atomic level represents a totally new world of fresh opportunities for design and engineering due to the new physics available at such a small scale. Feynman mentions this in his lecture, "Atoms on a small scale behave like nothing on a large scale, for they satisfy the laws of quantum mechanics" [1]. This new physics allows the manipulation of matter atom by atom. As Feynman further states, "The principles of physics, as far as I can see, do not speak against the possibility of maneuvering things atom by atom. It is not an attempt to violate any laws; it is something, in principle, that can be done; but in practice, it has not been done because we are too big" [1]. Feynman was right, and quantum mechanics continues to play a crucial role in miniaturization of technology. But advances in nanotechnology are not based purely on knowledge of the theory. Today we are realizing that all this "plenty of room at the bottom" has brought a great need for complex and ingenious metrology tools that accompany our knowledge of quantum mechanics. These metrology tools are necessary for atomic-scale manipulation as well as the characterization of each atom and its interaction with the environment. Feynman's lecture envisioned the need for significantly improved metrology tools. For example, he discussed improving the electron microscope by 100-fold. Today, in addition to the scanning electron microscope (SEM), we have the atomic force microscope (AFM), the scanning tunneling microscope (STM), and the near-field scanning optical microscope (NSOM), among many other metrology tools used for the advancement of nanotechnology [2]-[4], which Feynman did not foresee. These metrology tools also function as a platform for engineering novel atomic- and molecular-scale devices. This means performing logical operations with a single atom or molecule, manipulation of DNA molecules for information storage, or putting together nanomachines [2]-[4].
Performance Improvement of PM Synchronous Motor by Using Soft Magnetic Composite Material (2008)

The paper presents some aspects of soft magnetic composite (SMC) material application in electrical machines. The stator core of the analyzed permanent magnet synchronous motor (PMSM) is made of magnetic iron sheets. Three types PMSM stators are analyzed: laminated with open slots, laminated with closed slots using SMC, and SMC stators. The comparative analysis is based on the magnetic properties and the calculated parameters of each motor model. The studied electromagnetic and electromechanical parameters are flux densities in various sections of the magnetic circuit and electromagnetic torque. The parameters' values for the three types of stators are calculated using the finite element method (FEM).
P2835Feasibility and safety of same day discharge after radiofrequency catheter ablation for paroxysmal atrial fibrillation (2019)

Abstract Background Atrial fibrillation catheter ablation (CA) is the most frequent arrhythmia ablation and accounts for a significant proportion of treatment cost. Same day discharge (SDD) after paroxysmal atrial fibrillation (PAF) ablation is an attractive strategy for both patients and hospitals. Objective To understand the eligibility criteria and outcomes for PAF patients who can safely undergo same day discharge after radiofrequency catheter ablation. Methods Patients undergoing CA for PAF were evaluated for SDD at a pre-procedure visit to assess the risk of groin, respiratory, cardiac or bleeding complications. Eligibility criteria for SDD were stable anticoagulation and absence of bleeding history, systolic/diastolic heart failure, or interventional procedures within 60 days, with recommended BMI &lt;35. Patient proximity to the hospital was also considered. Anesthesia included propofol with endotracheal intubation and all patients were ablated with a porous tip contact force catheter (STSF). Patients were on bed rest for 6 hours post-procedure, then ambulated intermittently for 1–2 hours. Discharge followed if they were stable with no evidence of vascular access complications or bleeding. A dedicated RN telephoned patients the following morning to ask a series of standard questions designed to elicit evidence of any complications. Results 52 procedures were identified for SDD, with 7 patients declining. 45 planned SDD procedures for 43 patients occurred 4/17–6/18. Average age was 57±11 years and CHA2DS2-VASc was 1.5±1.1 at procedure. Procedure time was 69±26 min (IQR: 49 - 84 min) with maximum fluoroscopy usage of 0.2 min and 508±149 mL of fluid infused through the catheter. Two patients stayed overnight due a groin bleed and atelectasis with fever, and one chose to stay for comfort. The remaining 42 discharges occurred after 7.2±1.0 hours in recovery, with no SDD-related complications and no required return visits after the follow-up call. There were 3 AF recurrences (6.7%) as of the 10 week visit. Conclusion Appropriate low risk patients identified by simple clinical criteria can be safely discharged the same day after CA of PAF. Further evaluation is required for higher risk patients. Acknowledgement/Funding The study was funded by Biosense Webster Inc.
PROXIMAL HUMERAL FRACTURES TREATED WITH THE EVAN’S STAPLE (2002)

Introduction: The Evan’s staple is an intramedullary device. It has two 20 cm tines connected by a horizontal bar with a hole mid-apex to facilitate insertion over a K-wire and enhance fixation to the humerus by means of a tension band. Aim: To perform a retrospective review of the results of using the Evan’s staple as a means of fixation for displaced proximal humeral fractures. Method: Between 1989 and 1997 at the Toronto East General Hospital, 56 patients with displaced proximal humeral fractures were treated with an Evans’ staple. This included 14 three-part and four four-part fractures and six fracture-dislocations. The age range at the time of operation was 18–94 years. The average duration of follow-up was 48.6 months, the range being 11–99 months. The study consisted of patient chart review, radiological review and use of the DASH (Disabilities of the Arm, Shoulder and Hand) questionnaire. Results: Complete radiological data were available for 26 patients and these showed a 100% union rate. The majority (77%) healed in neutral, the remainder in varying degrees of varus. Twenty-one patients returned the DASH questionnaire, with an average functional score of 37.8 (0= no disability, 100= severe disability). The complications included eight cases of impingement that required staple removal and one fracture distal to a staple caused by a subsequent fall. Conclusion: The Evan’s staple is a viable means of fixation for displaced proximal humeral fractures.

Fat Graft Viability in the Subcutaneous Plane versus the Local Fat Pad (2014)

Investigation into fat graft injection location indicates that there is no statistically significant difference in angiogenesis signals between the subcutaneous plane and the local fat pad in the athymic rat model. Further research should aim to continue to close the gap between clinical practice and basic scientific understanding of fat grafting.
Separate Action Spectra for the Two Photochemical Systems of Photosynthesis (1966)

Action spectra have been obtained which are believed to represent the 2 photochemical systems in the marine green alga, Ulva lobata. Measurement of transient rates of O(2) uptake in the presence of DCMU furnished the data for the spectrum representing system I. The action spectrum for system II refers to O(2) evolution rates after the Ulva was pretreated in an atmosphere of high O(2) concentration. Tissue responses after high O(2) exposure suggests an inhibition of the photosynthetic functioning of system I.
Interpolation d'images couleurs sous échantillonnées par un modèle de perception (2001)

As in the visual system (in particular retina photoreceptors) where only one color is sampled at each spatial location, there is a kind of color images coming from so-called mono-CCD cameras, where there is only one color by pixel. This kind of color sampling is a spatial multiplexing of color information, mixing chromatic information with spatial dimension. We have studied this spatio-chromatic sampling in case of the human retina and found that it processes independently luminance information and opponent colors in the Fourier spatial spectrum. This analysis allow us to define an efficient interpolation algorithm for color images sampled by mono-CCD cameras.
Dynamic ray tracing for modeling optical cell manipulation (2010)

Current methods for predicting stress distribution on a cell surface due to optical trapping forces are based on a traditional ray optics scheme for fixed geometries. Cells are typically modeled as solid spheres as this facilitates optical force calculation. Under such applied forces however, real and non-rigid cells can deform, so assumptions inherent in traditional ray optics methods begin to break down. In this work, we implement a dynamic ray tracing technique to calculate the stress distribution on a deformable cell induced by optical trapping. Here, cells are modeled as three-dimensional elastic capsules with a discretized surface with associated hydrodynamic forces calculated using the Immersed Boundary Method. We use this approach to simulate the transient deformation of spherical, ellipsoidal and biconcave capsules due to external optical forces induced by a single diode bar optical trap for a range of optical powers.
Effect of Surface Modifications of SBA-15 with Aminosilanes and 12-Tungstophosphoric Acid on Catalytic Properties in Environmentally Friendly Esterification of Glycerol with Oleic Acid to Produce Monoolein (2018)

A series of protonated amino-functionalized SBA-15 materials was synthesized and tested as heterogeneous catalysts for the esterification of glycerol with oleic acid to produce monoolein. Mesoporous SBA-15 (S) was functionalized with three different aminosilanes: 3-aminopropyltriethoxysilane (N1); [3-(2-amino-ethylamino)propyltrimethoxysilane] (N2); and (3-trimethoxysilylpropyl) diethylenetriamine (N3), before being impregnated with 40 wt % 12-tungstophosphoric acid (HPW). The resulting nanocatalysts (S-Nx-HPW) were characterized by X-ray powder diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), N2 adsorption-desorption, SEM equipped with energy dispersive X-ray spectroscopy (SEM-EDX), transmission electron microscopy (TEM), and elemental analysis techniques. The presence of components of the nanocatalysts and the preservation of the hexagonal structure of SBA-15 were confirmed. Using different functionalizing agents considerably affected the textural properties and acidity of the synthesized nanocatalysts, which helped to improve the catalytic performance. In particular, S-N2-HPW was more active and selective than other catalysts in this study, as well as than a number of other commercial acid catalysts, with 95.0% oleic acid conversion and 60.9% monoolein selectivity being obtained after five h of reaction at 160 °C using 2.5 wt % of catalyst loading and glycerol/oleic acid molar ratio of 4:1. Aminosilane functionalization also helped to increase the reusability of the catalysts to at least six cycles without considerable loss of activity through strong electrostatic interactions between HPW anions and the protonated amino-functionalized SBA-15 materials.
Miscella refining (1976)

Abstract Miscella refining can be practiced as a batch process or, preferably, as a continuous process with oil concentrations through the range of 30–70% by wt of oil. Miscella refining is preferably practiced at the oilseed solvent extraction plant for the economic reason of single solvent recovery system. Three immediate benefits are lower refining loss, lighter colored refined oil, and elimination of water washing. Various types of chemical conditioning, mechanical conditioning, and combinations of both are discussed for miscella refining certain oils. Blends of compatible crude oils can be advantageously miscella refined and, if desired, winterized or hydrogenated to produce oils with unique properties.
Data Science Through the Looking Glass (2022)

The recent success of machine learning (ML) has led to an explosive growth of systems and applications built by an ever-growing community of system builders and data science (DS) practitioners. This quickly shifting panorama, however, is challenging for system builders and practitioners alike to follow. In this paper, we set out to capture this panorama through a wide-angle lens, performing the largest analysis of DS projects to date, focusing on questions that can advance our understanding of the field and determine investments. Specifically, we download and analyze (a) over 8M notebooks publicly available on GITHUB and (b) over 2M enterprise ML pipelines developed within Microsoft. Our analysis includes coarse-grained statistical characterizations, finegrained analysis of libraries and pipelines, and comparative studies across datasets and time. We report a large number of measurements for our readers to interpret and draw actionable conclusions on (a) what system builders should focus on to better serve practitioners and (b) what technologies should practitioners rely on.
Exploring the Plutonium Implosion Weapon: August 1944 to February 1945 (1993)

After August 1944, the implosion program began to engulf a growing fraction of the laboratory's personnel. Considerable research during the fall and following winter focused on experimental diagnostics. Seven parallel experimental programs – RaLa, betatron, magnetic, and electric pin studies, in addition to the original X-ray, photographic, and terminal observations – brought the most current techniques of experimental physics to bear on implosion problems. The foremost tasks were to determine the collapse time, compression, and symmetry, and to assess different explosives and explosive system designs. Informed trial and error was the approach most frequently taken in these simultaneous lines of experimental inquiry, since theoretical understanding was still incomplete. While each program offered its particular advantages, many efforts overlapped, adding modest confirmation to the amassing body of understanding. Despite lingering uncertainties about the feasibility of an implosion weapon, the six months following the August 1944 reorganization saw the central research question of the laboratory shift from “Can the implosion be built?” to “How can the implosion weapon be made?”
Effects of inter-organism interactions in biofouling on microtopographic surfaces (2019)

An extended model of the surface energetic attachment (SEA) model is introduced to study the fouling of marine organisms on microtopographic surfaces, taking into account the excluded volume interaction and the attraction between the organisms. It is shown that the excluded volume interaction leads to changes in the site-typed attachment probabilities which increase with the average spore density on the surface. As a result of these changes, the spore density map is flattened under very high density fouling. The attractive interaction on the other hand leads to aggregation of spores and the average aggregate size increased with the strength of attraction. The model can be mapped to a specific experiment to determine the attachment energy parameters. In contrast to various prior empirical approaches, the extended SEA model is rigorous from the statistical mechanics viewpoint, thus it provides a reliable tool for studying complex attachment behaviors of microorganisms on topographic surfaces.
A study on using sprinkle treatment to improve bituminous surfacings (1990)

Sprinkle treatment is a technique that applies a thin layer of highly polish-resistant precoated aggregates to the surface of a freshly placed, hot-mix wearing course, with a view to embedding into the surface during the rolling operation. This study investigates the effect of sprinkle treatment on durability of bituminous surfacings as regard skidding, stripping, and hardening. Granite, steel slag and a mixture of both are used as sprinkle aggregates. Sprinkle aggregates are precoated with penetration grade bitumen and its blend with either 5 per cent of natural rubber (discarded truck tyre) or 5 per cent of lime by weight of bitumen. From the laboratory test results, sprinkle treatment seems to offer two fold benefits to bituminous surfacings. Firstly, it provides an improved skid resistant surfacing, especially in areas where polish-resistant aggregates are not readily available in sufficient quantities or are expensive. Secondly, the treatment is able to improve the durability by reducing the hardening process of the bitumen and reducing the stripping tendency (A).

A universal fluorescence-based toolkit for real-time quantification of DNA and RNA nuclease activity (2019)

DNA and RNA nucleases play a critical role in a growing number of cellular processes ranging from DNA repair to immune surveillance. Nevertheless, many nucleases have unknown or poorly characterized activities. Elucidating nuclease substrate specificities and co-factors can support a more definitive understanding of cellular mechanisms in physiology and disease. Using fluorescence-based methods, we present a quick, safe, cost-effective, and real-time versatile nuclease assay, which uniquely studies nuclease enzyme kinetics. In conjunction with a substrate library we can now analyse nuclease catalytic rates, directionality, and substrate preferences. The assay is sensitive enough to detect kinetics of repair enzymes when confronted with DNA mismatches or DNA methylation sites. We have also extended our analysis to study the kinetics of human single-strand DNA nuclease TREX2, DNA polymerases, RNA, and RNA:DNA nucleases. These nucleases are involved in DNA repair, immune regulation, and have been associated with various diseases, including cancer and immune disorders.
A processing technique for the truncated projections of asymmetric-fan-beam transmission imaging (1995)

The authors have developed a new imaging geometry-the asymmetric-fan-beam (AsF)-to expand the imaging field of view (FOV) for transmission imaging on current SPECT systems. The AsF geometry samples slightly more than one-half of the FOV in each projection and yields half-truncated projection data. Although each projection profile is not complete, the combined acquired data set meets the minimum sampling requirement because the other half of the FOV is sampled in the opposite projections after a full 360/spl deg/ rotation of the detector system. To take advantage of the simple convolution-backprojection algorithm for reconstruction, the key is in the handling of the projection profile for convolution. The authors have investigated such a technique to process the truncated projection profile for reconstruction without the side effects caused by the truncation. This technique entails filling in the truncated portion of each profile with interpolated data derived from other projections. After convolution, only the corresponding half of the original projection profile is backprojected in reconstruction. This is done to minimize propagation of the errors of interpolation in the reconstruction. Reconstructed images from phantoms and human subjects demonstrate that this processing technique yields good quality transmission images.

All-cause and cause-specific mortality of immigrants and native born in the United States (2001)

Mortality patterns for immigrants and for US-born people vary considerably, with immigrants experiencing lower mortality from several major causes of death. Future research needs to examine the role of sociocultural and behavioral factors in explaining the mortality advantage of immigrants.
