Simple Method for Preparation of Porous Polyimide Film with an Ordered Surface Based on in Situ Self-Assembly of Polyamic Acid and Silica Microspheres (2010)

In this Article, we addressed a facile method for the fabrication of porous polyimide film with an ordered surface based on the solvent-evaporation-assisted in situ self-assembly of polyamic acid (PAA, precursor of polyimide) and silica microspheres during vacuum-drying of PAA/silica colloid solution. Hydroxyl groups on the surface of silica microspheres have strong hydrogen-bonding with PAA chains, which improve the dispersion of silica microspheres in PAA/DMF solution and further help the self-assembly of PAA/silica colloid solution via solvent evaporation. The approach is simple, neither the preparation of special template nor complex preparation process and precise control over condition is necessary. Furthermore, the method could be employed for mass production of ordered porous polyimide films, and by changing the content and size of silica microspheres, the pore size and porous structure of the porous polyimide films could be tunable. The wettability behavior of the as-prepared porous polyimide films is also studied; the ordered surface topography of the porous polyimide films could change the wettability from hydrophilicity to hydrophobicity.
Effective pupil dilatation with a mixture of 0.75% tropicamide and 2.5% phenylephrine: A randomized controlled trial (2009)

The mixture of 0.75% tropicamide and 2.5% phenylephrine is superior to our standard application of 1% tropicamide alternating with 10% phenylephrine. It provides faster and more successful pupil dilatation within 40 min.
Catalyzed hydrolysis of amide and peptide bonds in proteins (1942)

The rates of hydrolysis by dilute acids of both a dissolved protein (egg albumin) and an insoluble protein (wool) are shown to depend not only on the temperature and acidity but also on t he acid used. When hydrolyzed at 65 C by certain strong monobasic acids of high molecular weight, the amide and the peptide bonds are broken over 100 times as fast as when they are hydrolyzed with hydrochloric acid. Even among the common mineral acids, large differences appear. These differences in hydrolytic effectiveness parallel differences in the affinities of the anions of the acids for protein. A further reason for attributing t his effect to the anions is the attainment, with anions of high affinity, of a maximum rate of amide hydrolysis at r elatively low concentrations, stoichiometrically equivalent to the sum of the amino plus the amide groups. A similar limiting anion concentration or maximum rate of hydrolysis of t he much more numerous peptide groups is not observed. On the basis of details of t he dependence of the rate of hydrolysis on concentration of effective anions and hydrogen ions, a m echanism which involves combination of the groups hydrolyzed with hydrogen ions, is proposed.
Differentiation During Regeneration Caused by Migration of Repressors in Bioelectric Fields (1970)

Experiments are reviewed which have led to the conclusion that differentiation occurs during regeneration in Tubularia only if a bioelectric field of sufficient strength is maintained. The electrical polarity seems to determine the polarity of morphogenesis by controlling the movement of charged repressors. The repressors work in this totipotent system by preventing recipient regions from becoming what the donor regions are becoming. It appears that any level can become the most anterior structure not forming anterior to it. Thus by a series of repressions in totipotent material all levels of a hydranth are established.

A visceral pain pathway in the dorsal column of the spinal cord (1999)

A limited midline myelotomy at T10 can relieve pelvic cancer pain in patients. This observation is explainable in light of strong evidence in support of the existence of a visceral pain pathway that ascends in the dorsal column (DC) of the spinal cord. In rats and monkeys, responses of neurons in the ventral posterolateral thalamic nucleus to noxious colorectal distention are dramatically reduced after a lesion of the DC at T10, but not by interruption of the spinothalamic tract. Blockade of transmission of visceral nociceptive signals through the rat sacral cord by microdialysis administration of morphine or 6-cyano-7-nitroquinoxaline-2,3-dione shows that postsynaptic DC neurons in the sacral cord transmit visceral nociceptive signals to the gracile nucleus. Retrograde tracing studies in rats demonstrate a concentration of postsynaptic DC neurons in the central gray matter of the L6-S1 spinal segments, and anterograde tracing studies show that labeled axons ascend from this region to the gracile nucleus. A similar projection from the midthoracic spinal cord ends in the gracile and cuneate nuclei. Behavioral experiments demonstrate that DC lesions reduce the nocifensive responses produced by noxious stimulation of the pancreas and duodenum, as well as the electrophysiological responses of ventral posterolateral neurons to these stimuli. Repeated regional blood volume measurements were made in the thalamus and other brain structures in anesthetized monkeys in response to colorectal distention by functional MRI. Sham surgery did not reduce the regional blood volume changes, whereas the changes were eliminated by a DC lesion at T10.
Evaluation of Provisia Rice in Arkansas Rice Production Systems (2017)

With the continued evolution of herbicide resistance, it is becoming more difficult to achieve adequate weed control in Arkansas rice production systems. Thus, new technologies are needed to combat these troublesome weeds. A new non-GMO, herbicide-resistant rice type is under development that is resistant to quizalofop, an acetyl coenzyme A carboxylase (ACCase)-inhibiting herbicide that will allow for selective grass weed control in rice. With the commercialization of this technology by 2018, research was conducted to determine the best fit for quizalofop-resistant rice in current production systems. Experiments included evaluation of off-target movement of quizalofop, determination of plant-back risk from quizalofop application, best rate structure of quizalofop, general efficacy on common grass weeds, and tank-mix interactions of quizalofop with common herbicides used in rice. Overall, the risk for off-target movement of quizalofop on Midsouth grass crops is minimal, with injury only observed under conditions that would be rare in the field. Plant-back risk after quizalofop or other ACCase-inhibiting herbicide applications is relatively low, with only grain sorghum and corn showing potential for injury if planted in quick succession after herbicide application. Quizalofop applications in quizalofop-resistant rice are effective for controlling barnyardgrass, broadleaf signalgrass, and red rice, with the best results from sequential applications of quizalofop at 120 g ai ha-1. A screening of barnyardgrass accessions from across the state of Arkansas proved quizalofop to be an effective graminicides, controlling all accessions evaluated. Tank-mix research for quizalofop and common rice herbicides prove that caution needs to be taken when tank-mixing quizalofop, especially with acetolactate synthase-inhibiting herbicides and auxinic herbicides due to the risk of antagonism. Overall, this research supports that quizalofop-resistant rice can be an effective tool for Arkansas rice producers.
Effect of acetic acid on subcellular structures of cocoa bean cotyledons (1982)

Abstract Characteristic post‐mortem changes in subcellular structures are described which are caused by the penetration of acetic acid during incubation of cocoa seeds in aqueous media. In the storage cells lipid is agglomerated and separates from hydrophilic portions in proportion to the acetic acid concentration and pH. This effect is less pronounced at 50°C than at 40°C. In the absence of acetic acid or with very low concentration of undissociated acetic acid other substructural characteristics dominate in most of the cells. At 50°C Post‐mortem changes do not induce lipid agglomeration. At 40°C the intact protein vacuole swells and its matrix structure becomes spongy as a response to in‐vivo water absorption. Finally, it is shown that a concentration gradient persists in whole seeds for most of the time required for fermentation, because of the slow diffusion of acetic acid. The results are compared with temperature effects on subcellular structures and are discussed in relation to their significance for proteolysis in cocoa seeds during fermentation.
Death of a child as a result of familial hypercholesterolaemia (1989)

A 10-year-old boy died of a myocardial infarction; he had homozygous familial hypercholesterolaemia. Unrecognized tendon xanthomas previously had been removed. His parents and siblings were found to have elevated cholesterol levels. The screening of at-risk children allows the early recognition of hypercholesterolaemia and intervention in the development of atherosclerosis.
The Dense Plasma Focus: A Versatile Dense Pinch for Diverse Applications (2012)

The dense plasma focus (DPF) is a <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Z</i> -pinch that has been studied for 50 years. Within ten years of its discovery by Fillipov and Fillipova in Russia and Mather in the USA, this dense pinch was scaled up to 2-MA currents and neutron outputs of ~ 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">12</sup> /pulse. More remarkable is the fact that most of the relevant physics and scaling laws were elucidated within this first decade. The subsequent period has seen this type of pinch used as a teaching tool, developed as a portable neutron source for security applications, as a soft X-ray source for lithography, and as an energetic ion source for nanofabrication applications. This review builds upon several prior reviews. From the plasma physics standpoint, DPF physics is examined in light of fast <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Z</i> -pinches to examine the similarities. More cross-fertilization between the two communities is suggested as a means to improve both types of pinches. From the applications standpoint, the many uses of DPFs are summarized to demonstrate the versatility of these pinches. Their ease of assembly and relatively low voltage operation have allowed DPFs to be disseminated worldwide as fusion testbeds (unlike their fast <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Z</i> -pinch counterparts). Smaller or less economically developed nations have made valuable contributions to our understanding of the physics, as evidenced by the rich lode of publications that have advanced the field.
Isms (1983)

This essay is the relic of a projected history of ‘individualism in politics’. That enterprise – the reasons for abandoning it will be transparent from what follows – prompted some reflections which may be of more general interest. For no habit is better established in the humanities and social sciences, as well as in political speech, than that of constituting a subject-matter for oneself by means of an -ism. And while there may be instances where the context makes this practice unproblematic, a survey of the past and contemporary record of -isms gives grounds for suspicion and reservations.
Bending angle prediction and control of soft pneumatic actuators with embedded flex sensors – A data-driven approach (2017)

In this paper, a purely data-driven modelling approach is presented for predicting and controlling the free bending angle response of a typical soft pneumatic actuator (SPA), embedded with a resistive flex sensor. An experimental setup was constructed to test the SPA at different input pressure values and orientations, while recording the resulting feedback from the embedded flex sensor and on-board pressure sensor. A calibrated high speed camera captures image frames during the actuation, which are then analysed using an image processing program to calculate the actual bending angle and synchronise it with the recorded sensory feedback. Empirical models were derived based on the generated experimental data using two common data-driven modelling techniques; regression analysis and artificial neural networks. Both techniques were validated using a new dataset at untrained operating conditions to evaluate their prediction accuracy. Furthermore, the derived empirical model was used as part of a closed-loop PID controller to estimate and control the bending angle of the tested SPA based on the real-time sensory feedback generated. The tuned PID controller allowed the bending SPA to accurately follow stepped and sinusoidal reference signals, even in the presence of pressure leaks in the pneumatic supply. This work demonstrates how purely data-driven models can be effectively used in controlling the bending of SPAs under different operating conditions, avoiding the need for complex analytical modelling and material characterisation. Ultimately, the aim is to create more controllable soft grippers based on such SPAs with embedded sensing capabilities, to be used in applications requiring both a ‘soft touch’ as well as a more controllable object manipulation.
Does sleep disturbance predict depression in elderly people? A study in inner London. (1993)

Insomnia in elderly people has traditionally been regarded as inevitable and trivial. A longitudinal study was undertaken to examine the prevalence of sleep disturbance among elderly people in an inner London community and its association with demographic variables, depression, dementia and disability. Those aged 65 years and over living at home were interviewed using a validated and reliable semi-structured interview schedule. A total of 705 people were interviewed in 1987-88 and 524 were re-interviewed in 1990. Subjective sleep disturbance was found to be common (33% and 43%, respectively). Sleep disturbance was associated with being a woman, being unmarried, living alone, disability, and current and future depression, but not with dementia or older age. The best predictor of future depression in elderly people who were not depressed was current sleep disturbance. In the presence of current sleep disturbance, the traditional predictors of depression--being a woman, having a disability, being unmarried, living alone and being older--did not contribute further. This study has shown that sleep disorder is associated with pathology. Insomnia in elderly people requires assessment and this must be accompanied by the treatment of underlying disorders and monitoring of future health.
Dependence of the Spin Transfer Torque Switching Current Density on the Exchange Stiffness Constant (2012)

We investigate the dependence of the switching current density on the exchange stiffness constant in the spin transfer torque magnetic tunneling junction structure with micromagnetic simulations. Since the widely accepted analytic expression of the switching current density is based on the macro-spin model, there is no dependence of the exchange stiffness constant. When the switching is occurred, however, the spin configuration forms C-, S-type, or complicated domain structures. Since the spin configuration is determined by the shape anisotropy and the exchange stiffness constant, the switching current density is very sensitive on their variations. It implies that there are more rooms for the optimization of the switching current density with by controlling the exchange stiffness constant, which is determined by composition and the detail fabrication processes.
Peter Eisenman’s Romeo and Juliet (2000)

Etude de la relation entre architecture et ecriture chez P. Eisenman, dont l'oeuvre rejette la metaphysique anthropomorphique traditionnelle au profit d'une arche-texture fondee sur l'archetype de l'eros et de la tragedie represente par les noms de Romeo et Juliette.
Performance analysis of sleep mode operation in IEEE802.16e (2005)

The paper investigates the queueing behavior of the sleep mode operation in IEEE 802.16e for conserving the power of an mobile station (MS) in terms of the dropping probability and the mean waiting times of packets in the base station (BS) queue. In the sleep mode, when an MS wakes up at the end of each sleep interval and there is traffic addressed to it, this is notified in the listening interval immediately following the sleep interval. Otherwise, an MS again enters the sleep mode with a sleep interval which is double the length of the previous one. We modeled this sleep mode operation as M/GI/1/N with multiple vacations whose periods depend on the previous one. Our work may be a rough guide to understanding the BS queueing behavior according to parameters such as the minimum and maximum sleep interval, the BS queue size and the arrival rate of packets at a BS.
Excess heme in sickle erythrocyte inside-out membranes: possible role in thiol oxidation (1988)

Abstract It has been suggested that the development of sickle RBC membrane defects might be related to abnormal amounts of membrane-associated heme (a term we use in its generic sense to include hemoglobins, hemichromes, and free heme). Techniques previously used to measure membrane heme, however, would not distinguish between what is truly membrane-associated and what is merely trapped in RBC ghost preparations. Consequently, we have examined extensively washed inside- out membranes (IOM) prepared from normal and sickle RBC. Approximately 25% of the sickle ghost heme is lost upon conversion to IOM, but sickle IOM still have a significant excess (1.6 +/- 0.3 nmol heme/mg membrane protein compared with 0.7 +/- 0.2 nmol/mg for normal IOM, P less than .001). Amounts of ghost heme are only poorly predictive of amounts of IOM heme (r = .664). Preparation of IOM by using isotonic lysis with saponin yields virtually identical amounts of IOM heme. Small amounts of heme (less than 15%) can be displaced from IOM by using manipulations that elute spectrin, displace electrostatically bound proteins, or cleave the cytoplasmic portion of band 3. Treatment of IOM with dithiothreitol (DTT), however, displaces the most heme (35%), and this is almost reproduced (25% displacement) by the treatment of intact RBC with DTT before IOM preparation. Sequential treatment with all manipulations still leaves about 40% of the heme in sickle IOM, which indicates a compartment more intimately associated with the membrane. At least part of this is free heme without globin, as evidenced by abnormal binding of radiochloroquine to sickle IOM. Conversely, some IOM-associated globin is globin without heme because the measurement of globin per se markedly overpredicts amount of IOM heme. There is a strong correlation between RBC density and amounts of either ghost or IOM heme. Finally, the amount of membrane thiol oxidation (as measured by thiol-disulfide-exchange chromatography) does not correlate at all with ghost heme (r = .105), but it correlates well with IOM heme (r = .877, P less than .001). These data demonstrate that there are abnormal amounts of heme truly associated with sickle RBC membranes, and they are consistent with the hypothesis that this membrane-associated heme participates in the pathobiology of the sickle RBC membrane, particularly those aspects perhaps related to thiol oxidation.

Com isto, o artigo visa mostrar que o estudo da Bíblia a partir da realidade latino-americana pode colaborar para a construção de novas vivências de relações sociais, de gênero, classe e etnia.
Expression of AniA, the Major Anaerobically Induced Outer Membrane Protein of <i>Neisseria gonorrhoeae</i> , Provides Protection against Killing by Normal Human Sera (2000)

Anaerobically grown Neisseria gonorrhoeae has previously been shown to have elevated serum resistance in the absence of exogenous CMP-N-acetylneuraminic acid or detectable sialylation. We hypothesized that the anaerobically induced gonococcal outer membrane protein AniA might have a role in this phenomenon, as it is the only known gonococcal protein that is absent under aerobic conditions. An N. gonorrhoeae F62 derivative, RUG7035, in which aniA is under control of the tac promoter, was used to examine the effect of AniA expression on serum resistance. In this study, we found that expression of AniA enhanced the serum resistance of N. gonorrhoeae and may account for these earlier observations.
