Eye of horus – Erratum revealed a prescription survey

Background: The aim of this study was to survey the quality and the content of prescription of practitioners and also assess the legibility of alphabet, and short form of the drug.Methods: A survey of all prescription received by the patients that were written by general practitioners, consulting physicians and dentists in and around Virajpet and Madikeri (south Coorg) was included.The prescriptions were photocopied and returned back to the patients. The prescription was scored and analyzed by a qualified medical investigator.Results: A total of 171 prescription samples were collected. In most prescriptions, one or more aspects of patient’s personal details were missing. Concerned doctor’s details also lacked in most cases. 40.3% of the prescriptions were obtained wherein short form of the drug was used for prescribing drug. Legibility of alphabet was also evaluated and the most confusing letter noted in our study was letter “C”; followed by A, T, S, O, G, and D in this study the letter Rx was written in 7% of the prescription and in 19% prescription it was replaced by word “Adv” and 74% of prescription without symbol of Rx.Conclusions: The present data shows most prescriptions in the study was inadequate and important details were lacking, legibility of prescription was poor in rating

A nonlinear method of removing harmonic noise in geophysical data

A nonlinear, adaptive method to remove the harmonic noise that commonly resides in geophysical data is proposed in this study. This filtering method is based on the ensemble empirical mode decomposition algorithm in conjunction with the logarithmic transform. We present a synthetic model study to investigate the capability of signal reconstruction from the decomposed data, and compare the results with those derived from other 2-D adaptive filters. Applications to the real seismic data acquired by using an ocean bottom seismograph and to a shot gather of the ground penetrating radar demonstrate the robustness of this method. Our work proposes a concept that instead of Fourier-based approaches, the harmonic noise removal in geophysical data can be achieved effectively by using an alternative nonlinear adaptive data analysis method, which has been applied extensively in other scientific studies

Polymer supported ferrocene derivatives. Some <SUP>13</SUP>C CP-MAS NMR studies and use as hydrogenation catalysts

Polystyrene derivatives react with the lithioferrocenes Fe(&#951;5-C5H4Li)(&#951;5C5 H5),Fe(&#951;5-C5H5),Fe(&#951;5 -C5H4Li)2,Fe[&#951;5-C5 H3(CHMeNMe2)Li-1,2] [&#951;5-C5H5], and with lithium ferrocenylphosphines, to yield ironcontaining materials. The M&#246;ssbauer spectra confirm the loading of unstrained ferrocene fragments, some oxidized, in all cases. The 13C CP MAS NMR spectra also show the loading but the resolution (structural information) is not as good as can be obtained on model solid samples. Palladium(II) derivatives of the amine- and phosphine-containg materials are active hydrogenation catalysts for olefins. Double-bond migration also occurs in the case of 1-hexene

Thermal and collisional history of Tishomingo iron meteorite: More evidence for early disruption of differentiated planetesimals

Tishomingo is a chemically and structurally unique iron with 32.5 wt.% Ni that contains 20% residual taenite and 80% martensite plates, which formed on cooling to between -75 and -200 °C, probably the lowest temperature recorded by any meteorite. Our studies using transmission (TEM) and scanning electron microscopy (SEM), X-ray microanalysis (AEM) and electron backscatter diffraction (EBSD) show that martensite plates in Tishomingo formed in a single crystal of taenite and decomposed during reheating forming 10-100 nm taenite particles with ∼50 wt.% Ni, kamacite with ∼4 wt.%Ni, along with martensite or taenite with 32 wt.% Ni. EBSD data and experimental constraints show that Tishomingo was reheated to 320-400 °C for about a year transforming some martensite to kamacite and to taenite particles and some martensite directly to taenite without composition change. Fizzy-textured intergrowths of troilite, kamacite with 2.7 wt.% Ni and 2.6 wt.% Co, and taenite with 56 wt.% Ni and 0.15 wt.% Co formed by localized shock melting. A single impact probably melted the sub-mm sulfides, formed stishovite, and reheated and decomposed the martensite plates. Tishomingo and its near-twin Willow Grove, which has 28 wt.% Ni, differ from IAB-related irons like Santa Catharina and San Cristobal that contain 25-36 wt.% Ni, as they are highly depleted in moderately volatile siderophiles and enriched in Ir and other refractory elements. Tishomingo and Willow Grove therefore resemble IVB irons but are chemically distinct. The absence of cloudy taenite in these two irons shows that they cooled through 250 °C abnormally fast at >0.01 °C/yr. Thus this grouplet, like the IVA and IVB irons, suffered an early impact that disrupted their parent body when it was still hot. Our noble gas data show that Tishomingo was excavated from its parent body about 100 to 200 Myr ago and exposed to cosmic rays as a meteoroid with a radius of ∼50-85 cm

Hydrological and water chemical factors in the Yichang reach of the Yangtze River pre- and post-impoundment of the Three Gorges Reservoir: consequences for the Chinese sturgeon Acipenser sinensis spawning population (a perspective)

In order to understand the downstream hydrological and water chemical status after impoundment of the Three Gorges Reservoir (TGR) and to assess the impact of changes on the spawning of Chinese Sturgeon, we assessed hydrological factors (water temperature, water level, water discharge and sediment concentration), and some water chemical factors (dissolved oxygen and ammonia-N) at the Yichang spawning reach during pre- and post-impoundment periods. In addition, hydro-acoustic survey on the occurrence and distribution of Chinese sturgeon were undertaken and investigations on sturgeon-egg-eating predatory fishes were conducted to evaluate the spawning occurrence date of the Chinese sturgeon during autumn between 1997 and 2008. The main subject of interest is whether changes in spawning ground conditions occurred in pre- and post impoundment periods, from 1998 to 2008. After impoundment of TGR, when spawning occurred, many environmental factors decreased from pre-impoundment levels: sediment concentration (down 96.30%), water discharge (down 33.44%), flow velocity (down 12.20%) and water level (down 4.52%). Judging from the annual cycle, annual mean ammonia-N decreased by 50.9%, annual mean dissolved oxygen concentration also decreased by 9.6%. However, some factors increased: monthly average water temperature (increase 7.5% to a mean of 18.7 degrees C) in every Nov after impoundment. The analysis showed that the number of days with suitable water temperature for Chinese sturgeon spawning between Oct and Nov varied according to the highest impoundment level of the TGR. The annual natural spawning activity showed that there were two spawning periods each year from 1997 to 2002 (pre-impoundment period) with the exception of 1998, but there was only one spawning period each year from 2003 to 2008 (post-impoundment period). There was annual average 369 adults in 1998-2002, and there was annual average 231 adults in 2004-2008. There was annual spawning magnitude 3547.5 ten thousand eggs in 1997, and there was only 193.5 ten thousand eggs in 2008. The date for the beginning of spawning was delayed gradually by the impoundment of TGR. The later spawning periods may relate to a change in original water temperature rhythm in the Yichang spawning reach and reaching the upper limit of the spawning temperature in the fall after 2003 may also be the key to regulate occurrence of reproduction and its intensity
