Procesamiento de un gel silicoaluminoso utilizando el prensado axial como método de conformado (1992)

espanolSe ha demostrado la posibilidad de obtener materiales muUiticos de alta densidad, partiendo de un gel silicoaluminoso comercial con estequiometria 3:2, utilizando como metodo de conformado el prensado uniaxial. Se ha estudiado el efecto de distintas variables: granulo-metria, efecto del vibrado, presion de conformado y aglomerante en la densidad en verde y en la densidad y mi-croestructura de las muestras cocidas. Se han fijado los parametros de procesado que conducen a la obtencion de un material de muUita libre de efectos utilizando como aglomerante la carboximetilcelulosa. EnglishThe possibility of obtaining high density muUite bodies starting from a commercial 3:2 alumina/silica gel and uniaxial pressing as a forming method has been investigated. The effect of different processing variables: gra-nulometry, mould vibration, forming pressure and agglomerant, on green and fired densities, as well as on the microstructures of the fired bodies has been studied. The parameters to obtain a free of defects muUite body using carboximetilcelulose as agglomerant have been determined.
The Onset Time of Rocuronium Is Slowed by Esmolol and Accelerated by Ephedrine (2000)

Administration of ephedrine prior to rocuronium decreases the onset time of neuromuscular blockade from rocuronium by 26%. This effect was attributed to a increased cardiac output. If so, beta adrenergic-blocking drugs, which decrease cardiac output, should prolong the onset time of rocuronium. In a double-blind study, 60 patients were randomly assigned to three groups (n = 20) to receive either 70 microg. kg(-1) of ephedrine, 0.5 mg. kg(-1) esmolol or placebo, 30 s before induction of anesthesia. Onset time of rocuronium was defined as the time from the end of its injection to disappearance of all four twitches of the train-of-four. The onset time of rocuronium was significantly shorter after ephedrine (22%) and longer after esmolol (26%), as compared to placebo. No differences were observed among the three groups with regard to heart rate, systolic, diastolic or mean blood pressure. We concluded that a dose of 0.5 mg. kg(-1) of esmolol significantly prolongs the onset time of rocuronium with minimal hemodynamic changes.
Bullosis diabeticorum in a Newly Discovered Type 2 Diabetes mellitus (2000)

Bullosis diabeticorum (BD), although a rare manifestation, is characteristic of diabetes mellitus. The exact origin of BD is unknown. We report another case of a 54-year-old man who developed a blistering lesion on his left leg. Histopathological examination revealed a microangiopathy with hyalinosis of the blood vessel walls.
Aplicación de la topología molecular para la predicción de biodegradación anaerobia de clorofenoles (2013)

Se ha aplicado la topología molecular y el análisis de regresión multilineal en la búsqueda de un modelo de relación cuantitativa estructura-actividad (QSAR) capaz de predecir la capacidad de biodegradación anaerobia de un grupo de clorofenoles. Tomando el valor de la constante de velocidad de desaparición del derivado clorofenólico ,log k, como variable dependiente y los descriptores topológicos como variables independientes, se obtuvo una ecuación con tres variables y coeficientes de correlación y de predicción , R2=0.9291 y Q2=0.870. El modelo fue validado a través de una validación interna y un test de aleatoriedad. Los resultados obtenidos muestran una alta capacidad de predicción para la biodegradación de los compuestos analizados.

The Control of Wind Cooling of Wood Frame Building Enclosures (1991)

An extensive investigation of moisture problems in wood frame houses revealed that one of the most common problems was the formation of mould and mildew on inside wall surfaces of exterior corners (Van Poorten, 1983). The ma jority of the problem houses were of recent construction (around 1975), electrically heated yet "naturally ventilated." Clearly, inadequate ventilation was one of the con tributing factors. It was not possible to explain this occurrence solely in terms of thermal bridging, two-dimensional heat flow, hindered air circulation or lack of radiant heat gain. It was then suggested that additional cooling of wall surfaces resulted from defects in the sheathing which allowed wind to cool the wall construction in corners where a rapid change in wind pressure occurred. It was also suggested that in future housing, such problems could be largely avoided by providing airtight sheathing at building corners by moving the air barrier, customarily located on the room-side of the wall insulation, to the weather side where it would perform two functions (Timusk, 1983). A full-scale comer of a wood frame wall was built and evaluated for wind cooling effects in the laboratory. According to prediction, significant additional cooling did take place when defects in wall sheathing did exist and when the corner was exposed to a typical wind pressure gradient. The effectiveness of an externally-located air barrier was further demonstrated in a prototype house. Its installation and inspection was facilitated by locating it where it is not penetrated by joists, partition walls and electrical wires.
Spinal arthroplasty (2002)

Symptomatic degenerative spinal disease is a serious medical condition that affects many individuals. Modern neuroimaging modalities, the development of new medications, and advances in operative and nonoperative treatments have all contributed to improved outcomes. Unfortunately, there remain a significant number of patients in whom primary therapy either fails or new or recurrent symptoms develop over time. The last decade has witnessed the invention of devices designed to reconstruct the spinal motion segment. These devices can be divided into those that primarily function to replace a nucleus pulposus and those that completely replace the disc complex. In this article the author reviews the background leading to the development of the current group of disc replacements. The design and preliminary clinical results obtained using major lumbar and cervical devices are also reviewed.
Large Damping Enhancement in Dirac‐Semimetal–Ferromagnetic‐Metal Layered Structures Caused by Topological Surface States (2021)

Abstract This article reports damping enhancement in a ferromagnetic NiFe thin film due to an adjacent α‐Sn thin film. Ferromagnetic resonance studies show that an α‐Sn film separated from a NiFe film by an ultrathin Ag spacer can cause an extra damping in the NiFe film that is three times bigger than the intrinsic damping of the NiFe film. Such an extra damping is absent in structures where the α‐Sn film interfaces directly with a NiFe film, or is replaced by a β‐Sn film. The data suggest that the extra damping is associated with topologically nontrivial surface states in the topological Dirac semimetal phase of the α‐Sn film. This work suggests that, like topological insulators, topological Dirac semimetal α‐Sn may have promising applications in spintronics.
PHYSICO-CHEMICAL CHARACTERISTICS AND SORPTION CAPACITY OF BIOSYNTHETIC POLYMERS ON THE BASIS OF FERULIC ACID AND CONIFERYL ALCOHOL RESPECT TO ZEARALENONE MYCOTOXIN (2018)

The data about the chemical structure of the polymers, synthesized by the method of fermentative dehydropolymerization of ferulic acid, and also coniferyl alcohol, are presented. It is established that the polyferulic acids have practically identical element composition, but they differ, according to data of IR- and NMR-13C-spectroscopy, in the quantitative content of phenol and carboxyl groups. A study of their adsorptivity with respect to zearalenone mycotoxin is carried out, and the characteristics of specific surface area and capillary-porous structure are established. The calculations of the correlation relationships between the adsorptivity and the parameters of surface-porous structure and chemical structure of different models indicate to the key role of the mechanisms of chemical adsorption, whereas the contribution of physical phenomena is not essential. It is shown that the polymer, synthesized from the coniferyl alcohol, is characterized by the highest indices of adsorption.
Acoustically-Driven Microfluidic Systems (2000)

Abstract We have demonstrated a non-contact method of concentrating and mixing particles in a plastic microfluidic chamber employing acoustic radiation pressure. A flow cell package has also been designed that integrates liquid sample interconnects, electrical contacts and a removable sample chamber. Increased antibody binding to magnetic porous glass beads was observed in the presence of acoustic mixing due to improved mass transport. Concentration of glass and polystyrene beads using acoustic radiation pressure was also demonstrated.
Practical Synthesis of a Stable Precursor for Positron Emission Tomography Imaging Agent 18F-GTP1 (2020)

18F-GTP1 is a deuterated small molecule positron emission tomography (PET) imaging agent used to visualize tau tangles in Alzheimer’s disease patients. The first-generation synthesis of 18F-GTP1’s nonradiolabeled alkyl tosylate precursor was plagued by low-yielding steps, inefficient chromatographic purifications, and variable product quality. Due to these limitations, a more robust second-generation route was developed and successfully executed on kilogram scale. A reduction with LiAlD4 incorporated geminal deuterium atoms, while an efficient amidation reaction accessed the key acrylamide coupling partner. Moreover, the tricyclic imidazo[1,2-a]pyrimidine core was assembled via a novel, convergent, and highly selective phosphoramidate-directed annulation. The improved synthesis eliminated all chromatography en route to a high-yielding and reproducible acid-promoted tosylation as the final step.
Experimental Evaluation of a Collagen-coated Vicryl Mesh as a Dural Substitute (1992)

Dural substitutes must provide immediate restitution of a membranous covering for the brain without inducing any adverse reaction in the host or provoking adhesions to underlying nervous tissues. Ideally, the material should disappear completely and be replaced by tissues similar to the dura mater. In this study, parietal dural defects were created in 12 beagle dogs and closed with a vicryl mesh prosthesis made watertight by a film of bovine collagen. Clinical and biological tolerances were satisfactory. There was one case of early local infection. Gross and microscopic examinations performed between 7 days and 9 months after implantation showed degradation of the prosthetic mesh and connective tissue growth into the implant mimicking dura mater as early as 15 days after implantation. There was no attendant inflammatory reaction or cortical adhesions or other adverse reactions. The authors conclude that collagen-embedded vicryl mesh provides satisfactory biological function and compatibility when used as a substitute for dura mater in the dog.

Synthesis and photo‐induced dissolution of polymers bearing imino sulfonate groups (1989)

Abstract Novel photosensitive polymers were synthesized by the copolymerization of methyl methacrylate and 1,2,3,4‐tetrahydro‐1‐naphthylideneimino p ‐styrenesulfonate (NISS) and by the ternary polymerization of methyl methacrylate, methacrylic acid, and 9‐fluorenylideneiminop‐styrene‐sulfonate (FISS). NISS and FISS units showed good sensitivity to light of wavelengths below 300 nm and below 366 nm, respectively. Although the polymers were insoluble in aqueous alkaline solutions, on irradiation with UV light they became soluble in aqueous alkaline solutions. A remarkable decrease in molecular weight of the polymers was observed during the photolysis of imino sulfonate groups incorporated into the polymers, which assisted the dissolution of the irradiated polymers.
In situ X-ray area detector gain correction at an operating photon energy (2022)

Gain calibration of x-ray area detectors is a challenge due to the inability to generate an x-ray flat field at the selected photon energy that the beamline operates at, which has a strong influence on the detector's gain behavior. A method is presented in which a gain map is calculated without flat field measurements. Rather, a series of quick scattering measurements from an amorphous scatterer is used to calculate a gain map. The ability to rapidly obtain a gain map allows for a recalibration of an x-ray detector as needed without significant expenditure of either time or effort. Area detectors on the beamlines used, such as the Pilatus 2M CdTe or Varex XRD 4343CT, were found to have gains which drift slightly over timescales of several weeks or after exposure to high photon flux, suggesting the need to more frequently recalibrate for detector gain.
Laser irradiation of the guinea pig basilar membrane (2004)

Laser irradiation causes immediate alterations in collagen organization within the cochlea that can be visualized with polarization microscopy. These alterations may affect cochlear tuning. Ongoing research is aimed at analyzing the effect of laser irradiation on cochlear function. It is conceivable that this technique may have therapeutic benefits for patients with high-frequency sensorineural hearing loss.
Gene duplication and paleopolyploidy in soybean and the implications for whole genome sequencing (2007)

This analysis investigated both the structure of the paleopolyploid soybean genome and the potential effects retained homeology will have on assembling the whole genome shotgun sequence. Based upon these results, homeologous regions similar to those characterized here will not cause major assembly issues.
Targeting and Penetration of Virus Receptor Bearing Cells by Nanoparticles Coated with Envelope Proteins of Moloney Murine Leukemia Virus (2006)

One of the most important steps in a productive viral infection is when the virus fuses to a cell membrane and delivers its genome into the cell cytosol. This dynamic event is mediated by interactions between specific virus envelope proteins with their cell-bound receptors. This process is exemplified by Moloney murine leukemia virus (Mo-MLV) where envelope protein interaction with its receptor, mCAT-1, leads to virus-cell membrane fusion and infection of cells. Here, fluorescent nanoparticles (NPs) were coated with Mo-MLV derived membranes (Mo-NPs) by extrusion. Electron microscopy and biochemical analysis showed tight association of the virus membranes and NPs. The coated NPs mimic native virus by binding and entering only cells expressing the virus receptor. Confocal microscopy revealed that the coated NPs were taken up into endocytic compartments containing receptor and were also seen associated with caveolin, a marker of caveolae. To demonstrate that the Mo-NPs could escape endosomes and deliver a protein cargo into the cell cytosol, beta-lactamase (betalac) was covalently coupled to the Mo-NP cores and incubated with cells. betalac activity was only detected in the cytosol of mCAT-1-expressing cells. This is the first time that virus proteins have been used to specifically target NPs to receptor-bearing cells as well as penetration into the cell cytosol. Extrusion provides a rapid, detergent-free method to couple virus membranes to NPs and should be readily applicable for many other virus and NP types.
Dynamic identities for flexible access control (2005)

This thesis will analyse the pros and cons of a module-based approach versus the currently existing certiﬁcate schemes and the proposed requirements for a module-based certiﬁcate scheme to serve as a plausible identity veriﬁcation system. We will present a possible model and evaluate it in respect to the existing solutions and our set of identiﬁed requirements.
Modification of Electronic Properties of Mo2C Catalyst by Potassium Doping:  Impact on the Reactivity in Hydrodenitrogenation Reaction of Indole (2004)

The effect of potassium doping on electronic surface properties of molybdenum carbide (Mo2C) was investigated by species-resolved thermal alkali desorption techniques, work-function measurements, and density-functional theory calculations. The activation energies for desorption of K and K+ were determined and used for work-function assessment via the Schottky cycle. The results were compared with the parallel contact potential difference measurements, and a variation of the Fermi level upon doping was rationalized in terms of the potassium coverage and surface dipole moment. The tight correlation between the work-function changes and the rate constant of indole hydrodenitrogenation was observed and discussed in terms of electrophobic promotion.
Comparing two interface tools in performing visual analytics tasks (2009)

In visual analytics, menu systems are commonly adopted as supporting tools because of the complex nature of data. However, it is still unknown how much the interaction implicit to the interface impacts the performance of visual analysis. To show the effectiveness of two interface tools, one a floating text-based menu (Floating Menu) and the other a more interactive iconic tool (Interactive-Icon), we evaluated the use and human performance of both tools within one highly interactive visual analytics system. We asked participants to answer similarly constructed, straightforward questions in a genomic visualization, first with one tool, and then the other. During task performance we tracked completion times, task errors, and captured coarse-grained interactive behaviors. Based on the participants accuracy, speed, behaviors and post-task qualitative feedback, we observed that although the Interactive-Icon tool supports continuous interactions, task-oriented user evaluation did not find a significant difference between the two tools because there is a familiarity effect on the performance of solving the task questions with using Floating-Menu interface tool.
Length and dipole moment of TMV by laser signal‐averaging transient electric birefringence (1976)

Abstract Transient electric birefringence experiments have been performed on well‐characterized highly monodisperse samples of tobacco mosaic virus (TMV). Experiments and calculations are presented that show that the sensitivity and accuracy of the traditional transient electric birefringence technique can be enhanced by several orders of magnitude through the use of a low‐powered laser and crystal polarizing optics, signal averaging, and digital data processing. Measurements of the field‐free decay of the birefringence yield for the rotational diffusion coefficient, D R = 318 ± 3 sec −1 . The length of the rodlike virion, calculated from the Broersma equation with this value of D R and a rod diameter of 15 nm, is 292.5 ± 1.0 nm. Measurements of the growth of the birefringence when an electric field is applied across the sample yield μ 2 / k T (α ∥ − α ⊥ ) = 0.47 ± 0.07, where μ is the permanent dipole moment (assumed parallel to the symmetry axis of the virus) and α ∥ − α ⊥ is the electrical polarizability anistropy of the virus. Using the value of α ∥ − α ⊥ measured by O'Konski et al., we then obtain μ = 2.5 × 10 −14 esu cm.
A sequential transmission scheme for the multiple access channel with noiseless feedback (2009)

In this paper we study transmission of information over a multiple access channel (MAC) with noiseless feedback. We formulate this problem as a decentralized stochastic control problem, the three controllers being the decoder and the two encoders who, in the presence of limited information about each other, decide what to transmit at each time instance, in order to jointly achieve a common goal. Our contribution is two-fold. First, we identify structural properties of the optimal communication system that result in considerable simplification of the encoding/decoding process. The derived structural properties make it possible to consider transmission schemes that are akin to the posterior-matching scheme (PMS) for the point-to-point channel. Since the optimal communication system has this structure, we need only restrict attention to the study of those simplified systems, even when the optimal one is not known. Second, the aforementioned structural results allow us to view the original MAC system as an equivalent point-to-point communication system over a Markov channel with perfect state observation and delayed state feedback. Based on this equivalence, we derive a single-letter expression for the capacity of the original channel.

Erratum: First-principles calculation of spin-orbit torque in a Co/Pt bilayer [Phys. Rev. Mater. 3, 011401(R) (2019)] (2021)

In the original paper, the torquances were erroneously reported as functions of the orientation of the spin angular momentum rather than the magnetization m, which is opposite in sign due to the negative gyromagnetic ratio. Consequently, torque components that are odd in m were reported with the wrong sign. Specifically, the signs are wrong for the B 0 and B 0 coefficients listed in Table The arrows showing the odd torques and the colors showing the corresponding damping parameter C in Figs. 2(c) and 2(d) are also reversed.
Rapid Estimation of Potato Tuber Quality by Near‐Infrared Spectroscopy (2006)

Abstract Starch and protein parameters of potato tubers were estimated by near‐infrared (NIR) spectroscopy measurements of the crude potato mash. Calibration was carried out with a condensed data set of original 1481 individual samples from a varying number of varieties and breeding lines, grown at eight locations over a three‐years period. Validation of the models was performed with an independent data set ( n = 133). Starch content of potato tubers was determined with the official under‐water weighting procedure of the EU, and could be predicted with 90% confidence. The NIR model of phosphorus content of starch had a prediction confidence of 53%. Total protein content could be predicted, too (62% confidence), whereas the amount of coagulable protein was not predictable ( R 2 = 0.25). Despite the different qualification levels of the models, guiding to concrete prediction tools or to a very rough estimation graduating from “low” to “high”, the NIR technique enables potato starch processing plants to optimise both potato starch quality and processing efficiency.
