Hydrodynamic induced deformation of and orientation of a microscopic elastic filament

We describe simulations of an elastic filament immersed in a fluid and subjected to a body force. The coupling between the fluid flow and the friction that the filament experiences induces bending and alignment perpendicular to the force. With increasing force there are four shape regimes, ranging from slight distortion to an unsteady tumbling motion. We also find marginally stable structures. The instability of these shapes and the alignment are explained by induced bending and nonlocal hydrodynamic interactions. These effects are experimentally relevant for stiff microfilaments.

LSI-R Scores: Change Matters - Part II, Data Download, Iowa Department of Corrections

In the last issue of the Data Download, we discussed that overall, a 10% drop in LSI-R scores for our highest risk offenders was associated with a 6% reduction in recidivism. However, LSI-R score reductions for the lowest risk offenders don't substantially affect their already low recidivism rates. The issue contained charts that showed this held true for both probationers and parolees. The charts below show that change also matters for women offenders and African-American offenders.

LSI-R Scores: Change Matters - Part III, Data Download, Iowa Department of Corrections, June 2009

In this issue, we take a closer look at the individual risk factors measured by the LSI-R. There are several risk factors that the LSI-R assessment tool measures: Criminal History; Education/Employment; Financial; Family/Marital; Accommodations (Living Situation); Leisure/Recreation; Companions; Alcohol/Drug Problem; Emotional/Personal; and Attitudes/Orientation.

Offer and use of complementary and alternative medicine in hospitals of the French-speaking part of Switzerland.

BACKGROUND: In 2004, complementary and alternative medicine (CAM) was offered by physicians in one-third of Swiss hospitals. Since then, CAM health policy has changed considerably. This study aimed to describe the present supply and use of CAM in hospitals in the French-speaking part of Switzerland, and to explore qualitatively the characteristics of this offer. METHODS: Between June 2011 and March 2012, a short questionnaire was sent to the medical directors of hospitals (n = 46), asking them whether CAM was offered, where and by whom. Then, a semi-directive interview was conducted with ten CAM therapists. RESULTS: Among 37 responses (return rate 80%), 19 medical directors indicated that their hospital offered at least one CAM and 18 reported that they did not. Acupuncture was the most frequently available CAM, followed by manual therapies, osteopathy and aromatherapy. The disciplines that offered CAM most frequently were rehabilitation, gynaecology and obstetrics, palliative care, psychiatry, and anaesthetics. In eight out of ten interviews, it appeared that the procedures for introducing a CAM in the hospital were not tightly supervised by the hospital and were mainly based on the goodwill of the therapists, rather than clinical/scientific evidence. CONCLUSION: The number of hospitals offering CAM in the French-speaking part of Switzerland seemed to have risen since 2004. The selection of a CAM to be offered in a hospital should be based on the same procedure of evaluation and validation as conventional therapy, and if the safety and efficiency of the CAM is evidence-based, it should receive the same resources as a conventional therapy.

Part I. Iowa Railroad Investment Plan, 2009

The 2009 Iowa Railroad System Plan details the state’s role in providing and preserving adequate, safe and efficient rail transportation services to Iowans. The plan is intended to serve as a guide for decision makers and provides a basis for future Iowa DOT policy, funding priorities and programming decisions that affect rail transportation service in Iowa. The primary purpose of the 2009 Iowa Railroad System Plan is to guide the Iowa DOT in pursuing actions that maintain and improve railroad transportation in Iowa. The plan is a component of the Iowa Statewide Transportation Plan known as “Iowa in Motion.” This plan considers railroads from an intermodal perspective. Many commodities that move by rail also move by other modes (principally trucks) during part of their journey from origin to destination. The same is true of persons who use rail passenger service to make trips and who must also rely on other modes to access rail service. Therefore, railroads are part of larger intermodal freight and passenger transportation systems.

La pratique basée sur les résultats probants. Partie 2: Les étapes du processus [Evidence-based practice: Part 2: Steps in the process].

Evidence-based (EBP) aims for a new distribution of power centered on scientific evidence rather than clinical expertise. The present article describes the operational process of EBP by describing the implementation stages of this type of practise. This stage presentation is essential given that there are many conceptions end models of EBP and that some nurses have a limited knowledge of its rules ans implications. Given that number and formulation of the stages varies by author, the process presented here attempts to integrate the different stages reviewed.

Thermodynamic investigations in the Si-Ge-rich part of the ruthenium-silicon-germanium system

This paper reports molar heat capacities of Ru50SixGe(50-x) and Ru40SiyGe(60-y) ternary solid solutions determined by differential scanning calorimetry. A second order transition has been characterised for alloys ranging from Ru40Ge60 to Ru40Si10Ge50 at temperatures ranging from 850 to 1040 K, respectively. Tie lines have been established at 1000-900-800-700-600 degrees C by electron microprobe measurements on annealed alloys of the two phase domains: Ru50SixGe(50-x)-Ru40SiyGe(60-y) and Ru40SiyGe(60-y)-SizGe(100-z).

Etude de Nkx5-3, un facteur de transcription impliqué dans le développement de l'oeil

Résumé :Une famille souffrant d'un nouveau syndrome oculo-auriculaire, appelé syndrome de Schorderet-Munier, a été identifiée. Ce syndrome est caractérisé par une déformation du lobe de l'oreille et des anomalies ophtalmiques, notamment une microphtalmie, une cataracte, un colobome et une dégénérescence rétinienne. Le gène impliqué dans ce syndrome est NKX5-3 codant un facteur de transcription contenant un homéodomaine. Chez les patient atteints, le gène comporte une délétion de 26 nucléotides provoquant probablement l'apparition d'un codon stop précoce. Ce gène n'est exprimé que dans certains organes dont les testicules et les ganglions cervicaux supérieurs, ainsi que dans les organes touchés par ce syndrome, à savoir le pavillon de l'oreille et l'oeil, surtout lors du développement embryonnaire. Au niveau de la rétine, NKX5-3 est présent dans la couche nucléaire interne et dans la couche dè cellules ganglionnaires et est exprimé de manière polarisée selon un axe temporal > nasal et ventral > dorsal. Son expression in vitro est régulée par Spl, un facteur de transcription exprimé durant le développement de l'oeil chez la souris. NKX5-3 semble lui-même provoquer une inhibition de l'expression de SHH et de EPHA6. Ces gènes sont tous les deux impliqués à leur manière dans le guidage des axones des cellules ganglionnaires de la rétine. Pris ensemble, ces résultats nous permettent donc d'émettre une hypothèse quant à un rôle potentiel de NKX5-3 dans ce processus.Abstract :A family with a new oculo-auricular syndrome, called syndrome of Schorderet-Munier, was identified. This disease is characterised by a deformation of the ear lobule and by several ophthalmic abnormalities, like microphthalmia, cataract, coloboma and a retinal degeneration. The gene, which causes this syndrome, is NKX5-3 coding for a transcription factor contaning a homeodomain. In the affectd patients, the defect consists of a deletion of 26 nucleotides probably producing a premature stop codon. This gene is only expressed in a few organs like testis and superior cervical ganglions, as well as in organs affected by this syndrome, namely the ear pinna and the eye, mainly during embryonic development. In the retina, NKX5-3 is present in the inner nuclear layer and in the ganglion cells layer. It is expressed along a gradient ranging from the temporal retina to nasal retina and from the ventral to the dorsal part. Its in vitro expression is regulated by Spl, a transcription factor expressed during the murine eye development. NKX5-3 seems to inhibit the expression of SHH and EPHA6. These genes are both implicated, in their own way, in the axon guidance of the retinal ganglion cells. Taken together, these results allow us to make an assumption about a potential role of NKX5-3 in this process.
