Videopoetry : A Manifesto

"What follows is intended to distinguish videopoetry from poetry films, film poetry, poemvideos, poetry videos, cyber-poetry, cine-poetry, kinetic poetry, digital poetry, poetronica, filming of poetry and other unwieldy neologisms, which have been applied, at one time or another, to describe the treatment of poetry in film and video but which have also developed different and divergent meanings" -- p.

The Cyclamen graecum group, how many species?

Cyclamen graecum is a well-defined evolutionary unit that separated from other Cyclamen species about 10 million years ago (Yesson & Culham 2006; Yesson, Toomey & Culham, 2009). It is genetically isolated and there are no records of it hybridizing naturally with other species. However, over that time it has begun to form separate populations that themselves might later become species. The split between C. graecum subsp. graecum and C. graecum subsp. anatolicum, at 2.9-3.4mya, is older than the average speciation age of 2.3my for the genus Cyclamen (Yesson, Toomey & Culham, 2009), so it would be entirely consistent to treat C. graecum subsp. anatolicum as a species rather than a subspecies. Hildebrand’s name Cyclamen maritimum (Hildebrand, 1908, p291) is the earliest name available at species level. Therefore we propose that the the C. graecum group now comprises two species, one with two subspecies (Table 3). This would be consistent with species concepts elsewhere in the genus Cyclamen and properly reflect the genetic and geographic isolation of this element of the group

Microsatellite markers for hoop-petticoat daffodils (Narcissus sect. Bulbocodii; Amaryllidaceae)

• Premise of the study: Microsatellite markers were developed using hoop-petticoat daffodils ( Narcissus sect. Bulbocodii ; Amaryllidaceae) to aid in the taxonomic revision of the section, and further to evaluate their broad applicability for daffodil cultivar identification. • Methods and Results: Three hundred fifty-one primer pairs were developed using a commercial service. Nineteen polymorphic and repeatable markers were developed by screening 67 of these primer pairs. Of these, 11 chosen markers were used to screen 317 samples; the number of alleles per locus ranged from four to 21, and the observed heterozygosity ranged from 0.101 to 0.297. There were null genotypes in some samples for six of the markers. All the microsatellites were transferable to other Narcissus sections. • Conclusions: The results indicate that these new markers have sufficient potential variation to be used for taxonomic revision of the genus and to distinguish many commercial daffodil cultivars

Nutrition Specificities of Goat Kids in Suckling Period

In this paper the up to date methods and regulation of goat kids feeding as the new normatives and nutrient requirements are presented. In kids feeding remarkable attention has to be made on optimal needs concerning the accurate growth and progress. In order to make the best solution the updated normatives with large number of parameters have to be used. Growing goat kids require energy, protein, vitamins and minerals for optimum growth. Determining quantities of these nutrients needed will make possible to determine how much of grain mix and hay should be used to support maintenance and growth. The nutrient requirements of growing goats show a different trend than those of mature animals. The latest investigation results on protein level recommendation in kids feeding (NRC, 2007) have grown over 45%, while energy needs only infinitesimally more in regard to goat nutrient requirement needs considering the NRC recommendation from 1981. However, it must be remembered that energy requirements are based on minimal activity needed to secure feed and the actual requirement may very. Thus, the needs of energy for growing kids with a body mass of 20 kg is 5.69 MJ ME and 75.6 g in proteins. The first three days after birth are the most critical days in the life of a newborn kid. If the mother rejects the kids, colostrum of kids should be fed three times a day, a total of 2 to 3 pint per day. After three days, the kid diet is based on milk or milk replacer, which is given twice a day and does not exceed three liters per day. Feeding with milk or milk replacer may continue until 8-12 weeks or until the time the kids are weaned and able to consume 0.2 kg grain milk per day. At weaning, for feeding the 30 days old kids we used a mixture concentrate for early suckling kids. By own nutrient compounds this grain mixtures must have better quality than concentrate mixtures used in goat kids feeding. Provide a grain mix (kid starter) containing high levels of protein (16%) and high levels of fiber (11%) as well as good quality hay to encourage rumen development. After weaning up to 6 months, continue feeding with kid starter 0.2 to 0.4 kg/day and plenty of good quality forage and pasture. When the growing kids start to use large amounts of hay or green forage in feeding, they should be given a mixture of concentrate with something simpler composition. Do not feed silage and non-protein nitrogen at this age

A Corona Australis cloud filament seen in NIR scattered light. III. Modelling and comparison with Herschel sub-millimetre data

With recent Herschel observations, the northern filament of the Corona Australis cloud has now been mapped in a number of bands from 1.2um to 870um. The data set provides a good starting point for the study of the cloud over several orders of magnitude in density. We wish to examine the differences of the column density distributions derived from dust extinction, scattering, and emission, and to determine to what extent the observations are consistent with the standard dust models. From Herschel data, we calculate the column density distribution that is compared to the corresponding data derived in the near-infrared regime from the reddening of the background stars, and from the surface brightness attributed to light scattering. We construct three-dimensional radiative transfer models to describe the emission and the scattering. The scattered light traces low column densities of A_V~1mag better than the dust emission, remaining useful to A_V ~ 10-15 mag. Based on the models, the extinction and the level of dust emission are surprisingly consistent with a sub-millimetre dust emissivity typical of diffuse medium. However, the intensity of the scattered light is very low at the centre of the densest clump and this cannot be explained without a very low grain albedo. Both the scattered light and dust emission indicate an anisotropic radiation field. The modelling of the dust emission suggests that the radiation field intensity is at least three times the value of the normal interstellar radiation field. The inter-comparison between the extinction, light scattering, and dust emission provides very stringent constraints on the cloud structure, the illuminating radiation field, and the grain properties.Comment: 13 pages, 16 figures, accepted to A&

The long-term benefit of computer-assisted surgical navigation in unicompartmental knee arthroplasty

We reviewed the outcomes of 30 consecutive primary unicompartmental knee arthroplasties (UKA) performed by a single surgeon for medial compartmental osteoarthritis. Fifteen Allegretto knees were implanted without computer navigation and 15 EIUS knees were implanted with navigation. We compared the survivorship, radiological and clinical outcomes of the two groups at an average of 8.9 years and 6.9 years respectively. The patients were assessed clinically using the Oxford Knee Score (OKS) and radiologically using long-leg weightbearing films and non-weightbearing computed tomography alignment measurements. The overall survivorship was 86.7% at 9 years. A higher proportion of navigated knees were well aligned with a more reproducible position and malaligned knees tended to have a less favourable OKS. However, we found no statistically significant difference in survivorship, clinical outcome and radiological alignment between the two groups

Formation and evolution of interstellar filaments; Hints from velocity dispersion measurements

We investigate the gas velocity dispersions of a sample of filaments recently detected as part of the Herschel Gould Belt Survey in the IC5146, Aquila, and Polaris interstellar clouds. To measure these velocity dispersions, we use 13CO, C18O, and N2H+ line observations obtained with the IRAM 30m telescope. Correlating our velocity dispersion measurements with the filament column densities derived from Herschel data, we show that interstellar filaments can be divided into two regimes: thermally subcritical filaments, which have transonic velocity dispersions (c_s ~< \sigma_tot < 2 c_s) independent of column density, and are gravitationally unbound; and thermally supercritical filaments, which have higher velocity dispersions scaling roughly as the square root of column density (\sigma_tot ~ \Sigma^0.5), and are self-gravitating. The higher velocity dispersions of supercritical filaments may not directly arise from supersonic interstellar turbulence but may be driven by gravitational contraction/accretion. Based on our observational results, we propose an evolutionary scenario whereby supercritical filaments undergo gravitational contraction and increase in mass per unit length through accretion of background material while remaining in rough virial balance. We further suggest that this accretion process allows supercritical filaments to keep their approximately constant inner widths (~ 0.1 pc) while contracting.Comment: 16 pages, 8 figures, 1 table, 1 appendix.
