Sloan-r' photometry of Comet 17P/Holmes beyond 3.8 AU: An observing methodology for short-period comets far from perihelion

A photometric method is described for accurately quantifying the brightness of short-period comets far from perihelion. The method utilizes the Sloan Digital Sky Survey Catalog (Data Release 7) as a homogeneous source of reference star magnitudes. Results are based on SDSS-r' filtered images taken using 2.0-m aperture telescopes for which the exposure time was adjusted to achieve a constant motion-blur of 2.0 pixels (0.56 arcsec) on the CCD chip. Aperture photometry using circular and tilted elliptical apertures was performed on images, which were stacked to increase signal to noise. Magnitude dependence on 'seeing' was determined, and this calibration was used to normalize photometry to constant seeing thereby maximizing photometric accuracy. From observations of comet 17P/Holmes between 2008 October and 2009 March, a very significant outburst of 17P was found to have occurred on 2009 Jan 4.7 (\pm0.5 day). Night-to-night measurements of the brightness of the inner coma (3000-km radius) exhibited a scatter of only 0.015-0.019 mag. No short time-scale (&lt;36 hr) periodicity was found in the fading lightcurve. From literature data, it was estimated that reflected light from the nucleus contributed 7-11% of the signal within the inner coma and it is concluded that either the nucleus of 17P must be relatively spherical (projected axial ratio of &lt;1.25), or, if its shape is more typical of other comet nuclei, it has a rotational period in excess of 10 days (assuming the observations were not made with the nucleus 'pole-on' to the Earth). Evidence from intermittent activity displayed by the nucleus is indicative of a possible 44-day rotation period.

Malignant peripheral nerve sheath tumors associated with neurofibromatosis type 1: report of two clinical cases.

MPNSTs are sarcomas with a high index of recurrence with the ability to produce distant metastasis during early stages. Despite wide resection, patients did not survive due to the advancement and size of the lesions (determining factors in the prognosis). Due to the progressive growth of MPNST and the anatomic difficulty for its approach, there should be strict surveillance of patients with NF-1 for early detection of malignant transformation in these lesions.

Assessing Pathogenicity and Cultural Characteristics of Fusarium oxysporum f. sp. ricini Isolates from Major Castor Growing Regions of India

The present study was undertaken to investigate the pathogenicity and cultural characteristics of 20 isolates of Fusarium oxysporum f. sp. ricini, the causal fungus of wilt disease of castor (Ricinus communis L). Pathogenicity tests on the susceptible cultivar JI-35 revealed that all isolates were pathogenic, with symptoms progressing from yellowing and drooping of leaves to marginal necrosis, wilting and root discoloration. The incubation period varied significantly among the isolates, ranging from 10.0 to 22.5 days, while the per cent disease incidence (PDI) ranged from 51.7% to 100%. Cultural characterization that includes mycelial colour, colony morphology, pigmentation, growth habit and sporulation highlighted significant variability among the isolates of F. oxysporum f. sp. ricini. The colour of mycelium among the isolates ranged from white to various shades of pink and yellow, with growth habits observed as fast, moderate, or slow. Sporulation rates varied from very high to sparse among the isolates. The observed diversity in pathogenicity and cultural traits emphasized the presence of genetic variability in F. oxysporum f. sp. ricini isolates. These results are vital for understanding the pathogen virulence and for developing effective management strategies for wilt disease in castor crop.

Using Two-Pass 3D Pre-Stack Migration to Build Velocity-Depth Models in 3D

Prestack migration is a successful tool for imaging complex structures and has recently become quite popular. Experience with prestack migration indicates that the quality of the image is very sensitive to the velocity model, and therefore prestack migration is also used as a velocity analysis tooI. The migrated image is usually obtained in an iterative procedure and the velocity model is updated between iterations. In other words, prestack migration and velocity estimation are related procedures. The velocity model is required so a good depth image can be obtained while the migration process itself is the tool for deriving the velocity models.

Decrease in hypothalamic norepinephrine content following renal denervation in the one-kidney, one clip Goldblatt hypertensive rat.

Peripheral and central sympathetic mechanisms have been shown to contribute to the development and maintenance of increased blood pressure in the one-kidney model of renal hypertension in the rat.Previous studies from our laboratory have demonstrated that the renal sympathetic nerves, in particular, contribute to the maintenance of hypertension in this model.In those studies, renal denervation, performed 2 weeks after renal artery clipping, resulted in a significant decrement in blood pressure that was associated with a decrease in peripheral sympathetic activity.To further define the role of the renal nerves in the pathogenesis of hypertension in this model, we determined the systolic blood pressure and norepinephrine and dopamine content of the hypothalamus, midbrain, pons medulla, and spinal cord at 1 week following renal denervation or sham operation of rats with early established one-kidney one clip hypertension.Age-matched uninephrectomized rats were controls.The blood pressure of denervated animals decreased significantly from 189 ± 9.21 to 151 ± 6.5 mm Hg (p < 0.001), while that of sham-operated animals did not change.Hypothalamic norepinephrine content of sham-operated animals was significantly greater than that of controls (2.24 ± 0.8 Mg/g sham vs 1.84 ± 0.12 Mg/g controls, p < 0.01).Renal denervation resulted in a decrease in hypothalamic norepinephrine content to control levels (1.72 ± 0.11 Mg/g)-There was a significant (r = 0.65, p < 0.01) positive correlation between systolic blood pressure and hypothalamic norepinephrine content of renaldenervated and sham-operated animals.The norepinephrine content of other brain regions was not different between groups.The results suggest that the renal nerves contribute to the maintenance of hypertension in the one-kidney one clip rat by modulating central sympathetic nervous system activity.(Hypertension 4: 369-373, 1982) KEY WORDS • renal hypertension • renal afferent nerves • central noradrenergic nervous systemE VIDENCE from a number of laboratories indicates that increased activity of the sympathetic nervous system is important in the pathogenesis of hypertension in the one-kidney one clip Goldblatt model of renal hypertension in the rat. 1 " 14 Plasma norepinephrine, used as an index of peripheral sympathetic activity, has been found to be

Perceptual learning of dysarthric speech : effects of familiarization and feedback

The current study investigated the presence of perceptual learning following familiarization with spastic dysarthric speech secondary to cerebral palsy. The phonemic level of speech perception was examined using the word-initial stop voicing contrast. Stimuli were produced by a male speaker with severe spastic dysarthria. Speech samples were selected from the speaker’s utterances based on negative voice-onset time (prevoicing duration). Stimuli were systematically selected to create the voicing contrast using tokens with either short prevoicing or abnormally long prevoicing durations. Thirty naïve listeners were randomly assigned to one of three familiarization groups: one group was provided written feedback during familiarization, the second group listened to the same stimuli but was not provided with feedback, and the third group listened to different stimuli, which did not contain the voicing contrast. A forced-choice testing format was used to measure listeners’ responses preceding and following familiarization. Results showed changes in listeners’ response patterns following familiarization across the three groups indicating that perceptual learning occurred. Theoretical, clinical, and design implications are explored.

An empirical study of working memory, personality, and second language construction learning

Abstract The study presented in this chapter investigated the role of individual differences in construction learning under different conditions of partial repetition. Ninety participants were exposed to an artificial system of noun-suffix constructions under one of three incidental learning conditions, which either repeated nouns across consecutive trials, repeated suffixes across consecutive trials, or contained no repetition across consecutive trials. It was hypothesized that: (a) working memory (WM) and (b) openness would predict L2 construction learning, and that (c) the influence of WM would be stronger in the absence of repetition, while (d) intellect would be associated with attention to form. The results indicated that participants learned the artificial system, with no differences between conditions. Measures of WM and openness correlated positively and significantly with untrained (i.e. generalization) test scores. Mixed-effects binominal regression models revealed significant effects for WM, but showed no interactions between condition and WM. Intellect was significantly related to a measure of attention. In sum, this study provides additional evidence that WM fosters generalization and further suggests that the distinction between openness and intellect may be useful for understanding novel second language learning.
