Coupling a Global Heliospheric Magnetohydrodynamic Model to a Magnetofrictional Model of the Low Corona
Authors: Hayashi Keiji , Abbett William P. , Cheung Mark C. M. , Fisher George H. 
Published: April 2021

Abstract
Recent efforts coupling our Sun-to-Earth magnetohydrodynamics (MHD) model and lower-corona magnetofrictional (MF) model are described. Our Global Heliospheric MHD (GHM) model uses time-dependent three-component magnetic field data from the lower-corona MF model as time-dependent boundary values. The MF model uses data-assimilation techniques to introduce the vector magnetic field data from the Solar Dynamics Observatory/Helioseismic and Magnetic Imager, hence as a whole this simulation coupling structure is driven with actual observations. The GHM model employs a newly developed interface boundary treatment that is based on the concept of characteristics, and it properly treats the interface boundary sphere set at a height of the sub-Alfvénic lower corona (1.15 R
⊙ in this work). The coupled model framework numerically produces twisted nonpotential magnetic features and consequent eruption events in the solar corona in response to the time-dependent boundary values. The combination of our two originally independently developed models presented here is a model framework toward achieving further capabilities of modeling the nonlinear time-dependent nature of magnetic field and plasma, from small-scale solar active regions to large-scale solar wind structures. This work is a part of the Coronal Global Evolutionary Model project for enhancing our understanding of Sun–Earth physics to help improve space weather capabilities.
Cave-adapted beetles from continental Portugal
Authors: Reboleira Ana Sofia P. S. , Eusébio Rita 
Published: April 2021

The cave biodiversity of continental&nbsp;Portugal faces tremendous conservation challenges, mostly linked to their&nbsp;direct destruction and contamination infiltrating from surface.&nbsp;Beetles are the most diverse insects and one of the most diverse arthropod groups&nbsp;in caves of Portugal.
We present the IUCN Red List profiles for the cave-adapted beetles from continental Portugal, all endemic to their respective geological units and massifs. Ground beetles (Carabidae)&nbsp;are the most diverse family of cave-adapted beetles in continental Portugal, followed by rove beetles (Staphylinidae). Beetles in caves of Portugal are mostly terrestrial and only&nbsp;one species is known to have&nbsp;evolved to live in&nbsp;groundwater.&nbsp;Trechus&nbsp;is the most diverse&nbsp;genus with four species, followed by&nbsp;Domene&nbsp;with three species, and by&nbsp;Speonemadus&nbsp;and&nbsp;Iberoporus, both with one cave-adapted species.&nbsp;The aim of this contribution is to assess all endemic&nbsp;cave-adapted species of beetles from continental Portugal and to support their&nbsp;specific protection, to promote&nbsp;an adequate management of surface&nbsp;habitats and the establishment of priority areas for conservation.
This&nbsp;document&nbsp;can&nbsp;be&nbsp;used&nbsp;in&nbsp;spatial&nbsp;planning&nbsp;and&nbsp;territory&nbsp;management&nbsp;in&nbsp;karst,&nbsp;based&nbsp;on the&nbsp;current&nbsp;scientific&nbsp;knowledge.
Un autre paysage dans une perspective de sobriété énergétique
Authors: Doreau Auréline 
Published: April 2021

Pour viser la maîtrise de l’énergie, il est nécessaire aujourd’hui de construire un nouveau récit commun du paysage urbain et rural : des bassins de vie plus resserrés, des densifications d’usages sur un même lieu, des échanges humains accrus… Si des démarches existent, mises en valeur par l’École nationale supérieure de paysage (ENSP), la sobriété énergétique est encore peu palpable.
La transition se dessine par la base

Published: April 2021

À cheval sur l’Indre et le Cher, marqué par un paysage verdoyant fait de vallons et de bocages, le Boischaut Sud, territoire affecté par les problématiques caractéristiques de nombreux territoires ruraux, voit depuis plusieurs années les initiatives alternatives essaimer. La dynamique de transition prend aujourd’hui de l’ampleur et se concrétise dans la démarche « Boischaut Sud en Transition », qui rassemble les forces vives et refonde le rapport au territoire.
Ordonner des pasteurs
Authors: Legrand Hervé 
Published: April 2021

Les déséquilibres doctrinaux de la théologie courante de l’ordination aggravent la crise actuelle du clergé. Selon la Tradition, les pasteurs étaient situés dans leur Église et en vis-à-vis d’elle. Actuellement, prêtres et évêques sont surtout envoyés à leur Église, après une ordination qui les fait personnellement prêtres ou évêques, et en second lieu pasteurs d’une Église, après coup. Cet accent sur la personne individuelle des ministres (vocation antérieure à l’appel de l’Église ; pouvoirs personnellement possédés ; identification au Christ), grève l’ecclésiologie de communion et met l’accent sur l’Église comme organisation. L’évangélisation bénéficierait du retour aux équilibres traditionnels analysés dans l’article.
Le « sacerdoce » dans le discours catholique avant Vatican II
Authors: Chiron Jean-François 
Published: April 2021

Le discours catholique sur le sacerdoce ministériel avant Vatican II peut être étudié à partir des textes pontificaux de la première moitié du XX e siècle et d’une lettre pastorale du cardinal Suhard. Ces documents représentent les états ultimes d’une tradition qui fait du prêtre un homme séparé du peuple, médiateur entre Dieu et les hommes, dans une perspective christologique qui finit par définir son sacerdoce comme participation au sacerdoce du Christ. La prise de conscience, dans les décennies précédant le concile, de la nécessité d’un rôle « missionnaire » conduisit à vouloir faire du prêtre, homme séparé, un homme immergé dans le monde qu’il doit évangéliser. Il n’est pas sûr que le recours, alors renforcé, à la thématique de la médiation sacerdotale ait suffi à honorer un programme aussi ambitieux, sinon contradictoire.
Ce que la liturgie donne à voir des ministères
Authors: Prétot Patrick 
Published: April 2021

Le contexte actuel de crise sanitaire mondiale et de crise des abus dans l’Église, invite les théologiens à renouveler leurs approches. Ceci vaut pour la question des ministères en liturgie. Parce que les célébrations « donnent à voir » ce que les discours peuvent omettre de considérer voire ce que l’on peut parfois chercher à occulter, la liturgie est en quelque sorte le miroir des impensés en matière ecclésiologique, ces présupposés qui suscitent des réactions spontanées au changement ou qui soutiennent des évidences ou des habitudes non critiquées. En relisant certains aspects de l’héritage du dernier Concile, l’article s’attache à mettre en lumière les apories que créent les décalages entre les discours et les pratiques.
Le sous-sol ou de la précarisation des subjectivités comme outil de la précarisation du travail
Authors: Karam Heliete

Il s’agit d’une intervention en psychodynamique du travail auprès de l’équipe de santé d’un centre de soins pour usagers d’alcool et de drogue, au Brésil. Y ont participé des psychologues, des médecins, des assistantes sociales, des infirmières, des ergothérapeutes, des aides-soignants et des agents administratifs. Les discussions ont porté sur les souffrances vécues par les membres de l’équipe dans le cadre de leur travail. Le point de départ a été le mot « sous-sol » – désignant initialement l’emplacement physique où l’équipe avait été installée par l’établissement public auquel elle était affectée. Nous soulignons comme résultat positif majeur le fait que l’équipe a réussi à transformer son organisation du travail, et cela dans la mesure où elle a attribué collectivement et coopérativement au mot « sous-sol » une nouvelle signification. Cependant, au-delà de la clinique, mais, à travers elle, ce texte propose d’illustrer comment la précarisation des subjectivités est utilisée par le néolibéralisme comme outil pour la mise en œuvre de la précarisation du travail.

Marchés démoralisés. Un retour critique sur le paradigme de la reconnaissance
Authors: Saburova Daria 
Published: April 2021

Le concept de la reconnaissance, forgé dans les années 1990 par Axel Honneth, est désormais solidement installé au sein des disciplines empiriques ayant pour objet le monde du travail. L’évolution théorique du philosophe francfortois, marquée par l’abandon progressif de la centralité normative des luttes sociales au profit de la centralité normative des institutions, notamment du marché capitaliste du travail, laisse cependant un doute quant au potentiel critique du paradigme de la reconnaissance. Cet article vise à examiner les limites du modèle de la reconnaissance développé par Honneth dans Le Droit de la liberté . Il soumet également à la discussion les corrections apportées à ce modèle par Hans-Christophe Schmidt am Busch dans son essai récent Qu’attendons-nous du travail ?
TEACHING NURSING DIAGNOSES TO SCHOOL NURSES: A Curriculum Plan
Authors: Dunn Joan Dolce , Crosby Frances Stevralia 
Published: April 2021

ABSTRACT
This article will describe the development, implementation and evaluation of a continuing education program entitled "Nursing Diagnosis in School Nursing Practice." Designed for school nurses, the curriculum uses an experiential approach. The program's effectiveness was evaluated both in the classroom and in the school nurses' clinical practice setting via case studies and analysis of daily logs. Feedback was gathered regarding the value of the educational offering and the importance of nursing diagnosis in practice. Results of the program evaluation suggested a significant change in the learners' knowledge and application of nursing diagnoses. Clinical evaluation indicated that the nurses demonstrated an increased discrimination of their nursing domain. Nurse participants reported that both the continuing education program and the utilization of nursing diagnoses in their clinical practice were worthwhile. The experiential model for teaching nursing diagnosis to school nurses was supported as an effective way to impact upon clinical application of nursing diagnosis.
Nursing Ethics: Essential Component of Continuing Education
Authors: Cragg Catherine E 
Published: April 2021

ABSTRACT
Ethical behavior is an essential component of professional practice. In recent years, nursing has become increasingly aware of the need to prepare its practitioners for making the ethical judgments required by everyday practice. Nursing ethics has been emphasized in the curricula of undergraduate schools of nursing. Books and articles on the dilemmas nurses face and how to deal with them have been written. Research has been undertaken on factors which influence nurses' abilities to reach ethical conclusions. Little has been said, however, about the need for continuing education in ethics for nurses.
BILATERAL ADRENAL HEMORRHAGE: A COMPLICATION OF PROPHYLACTIC ANTICOAGULATION
Authors: Head William C , Bynum Lincoln J 
Published: April 2021

ABSTRACT: The following case report presents a rare complication, bilateral adrenal hemorrhage, following low dose heparin prophylaxis for deep vein thrombosis in a 59-year-old total hip replacement patient. Symptoms associated with adrenal hemorrhage included nausea, vomiting, epigastric pain, increased temperature and white blood-cell count, and a drop in the hematocrit. At no time either pre- or postoperatively were hematological studies abnormal.
Adrenal hemorrhage has been documented following therapeutic doses of heparin but is exceedingly rare following low doses of the drug. It has rarely been diagnosed before death occurred. It is concluded that use of low doses of heparin for prevention of deep vein thrombosis is of limited efficacy in patients undergoing total hip replacement surgery and its routine use is therefore not recommended.
WEIGHT BEARING IN PERTHES' DISEASE
Authors: Bellyei Árpád , Mike George 
Published: April 2021

ABSTRACT
Results of two different types of treatment for 82 varus-derotation femur osteotomies to cure Perthes' disease are presented. Patients were treated between 1974 and 1984. Postoperatively, in 30 cases weight bearing was allowed, while in 52 cases, non-weight bearing braces were applied. Comparing the results of the two groups and considering the risk factors, the authors found that non-weight bearing does not influence end results after proximal femur osteotomy.
INSTABILITY IN SPONDYLOLISTHESIS
Authors: Friberg Ora 
Published: April 2021

ABSTRACT
Anteroposterior translation as a sign of segmental instability was documented by tractioncompression radiography in the majority of lumbar segments presenting lytic or degenerative spondylolisthesis with normal disc space height Severity of lower back pain symptoms correlated with the degree of instability, but not with the amount of static spondylolisthetic displacement. Unstable spondylolistheses exhibited decreased viscoelastic behavior with creep, the degree of the vertebral displacement being dependent on the amount and duration of load. Disc degeneration and traction spurs seemed to be factors that may stabilize spondylolisthesis, even at an early age.
ERYTHROCYTE SEDIMENTATION RATE IN INFECTION OF TOTAL HIP REPLACEMENTS
Authors: Thorén Björn , Wigren Anders 
Published: April 2021

Abstract
Erythrocyte sedimentation rate was studied in 79 patients who underwent reoperations for prosthetic hip failures. Fifty-one patients had infected prostheses, confirmed on the basis of sinus formation and cultures taken at the revision operation. Twenty-eight had proven mechanical loosening of their hip prostheses, as five out of five intraoperative cultures were negative. An ESR level of 35 mm was found to represent an acceptable borderline between infected and non-infected prostheses.
INFLUENCE OF BONE STAPLE DESIGN ON INTERFRAGMENTARY COMPRESSION
Authors: Krackow Kenneth A , Mecherikunnel Paul 
Published: April 2021

ABSTRACT
Staple fixation, most commonly thought of as static, has been studied with regard to effecting dynamic compression. Features of staple design that relate to the creation of interfragmentary compression have been analyzed, and a simple manipulative technique to effect compression is illustrated. Compressive forces of bone fixation staples were measured using pressure-sensitive film. Thirteen staple designs were tested in a wood-block model and in cadaveric bone. Staples with legs splayed outward produced higher compressive forces than standard staple designs. Internal beveling of the staple leg tips also produced high compressive forces, while external beveling produced distraction. Staples with legs tapered over their entire length produced compression, but caused splitting in the woodblock model. Our results show that outward splaying of the staple legs is a simple method to increase compression in any staple design.
Comparison of General and Epidural Anesthesia in Patients Undergoing Primary Unilateral THR

Published: April 2021

ABSTRACT
One hundred ninety-five consecutive patients underwent 195 primary unilateral total hip arthroplasties between January 1988 and December 1993. Patients were divided into three groups based on the type of anesthesia utilized for their procedure. Group I consisted of 108 patients (59 women and 49 men; average age 56 years) who had general endotracheal anesthesia alone. Group Il consisted of 70 patients (41 women and 29 men, average age 58 years) who had general endotracheal anesthesia with epidural augmentation intraoperativeiy and postoperatively. Group III consisted of 17 patients (6 women and 11 men, average age 62 years) who had epidural anesthesia only. Data were analyzed by anesthesia group to compare a variety of clinically relevant factors. No statistically significant differences among groups were noted regarding average age at surgery, the underlying diagnoses leading to joint replacement, the number of preexisting medical conditions, length of hospitalization, nonsurgical operating room time, intraoperative blood transfusions, intraoperative femur fractures, deep venous thrombosis, deep infections, death, or the prevalence of postoperative urinary tract infections. Postoperative urinary tract infections correlated with duration of Foley catheterization, but not the duration of epidural catheterization. Significant differences among anesthesia groups were observed for two factors: 1) estimated intraoperative blood loss was highest for Group I (P < .05) and was primarily a function of surgical time (P < .0001), and 2) postoperative Hemovac output (over the first and second postoperative 24-hour periods) was greatest for Group II (P < .05). Epidural anesthesia appears to be a safe modality in patients undergoing primary unilateral total hip replacement.
Comparison of Warfarin Use in Total Knee Replacement vs Total Hip Replacement
Authors: Alexander Gerald , Gustafson Allen , Wise Gregory 
Published: April 2021

ABSTRACT
The purpose of this retrospective study was to determine the efficacy of warfarin prophylaxis against deep vein thrombosis (DVT) in total hip arthroplasty (THA) vs total knee arthroplasty (TKA). A review of venograms in 223 patients with THA and in 189 cases of TKA was carried out. The overall DVT rate in THA was 22%. The overall DVT rate in TKA was 46%. We conclude that combined or alternate methods need to be used to decrease the rate of DVT following TKA to that of THA.
The Orthopedic and Social Outcome of Open Tibia Fractures in Children

Published: April 2021

ABSTRACT
To determine whether the accepted principles of management of open tibia fractures apply to children, 40 consecutive open fractures of the tibial shaft in skeletally immature patients were retrospectively reviewed. Attempts were made to evaluate the functional and social impact of open tibia fractures in children. All open fractures were initially treated by rapid irrigation and debridement which was repeated every 48 hours until soft tissues stabilized. The average age was 10.1 years and average follow up was 26 months (range: 1 8 to 84).
There were 1 6 grade I, ? 0 grade II, and 1 4 grade III open fractures. The grade III fractures were further subdivided into 6 grade HlA, 7 grade IHB, and 1 grade UIC. The average time to union was 7.5 and 1 1 .0 weeks in the grade I and Il fractures respectively, with no infections and no delayed unions. In grade III fractures, the average time to union was 15 weeks, with 1 infection and 3 delayed unions. Bone grafting using autogenous iliac crest was performed on 2 patients. The children surveyed missed an average of 4.1 months of school and 33% had to repeat a year. Twenty-five percent of the children complained of nightmares involving the events of the accident. Chronic pain despite solid union was found in 30% of patients. Forty percent of those surveyed (7 grade III fractures) complained of a limp.
The low incidence of soft tissue complications and infections in the study population supports applying in children the same basic soft tissue management principles of open fracture treatment as used in adults. While bone stabilization options are limited in children, the rate of successful union without adjunctive bone grafting is much higher than that of adults treated under similar protocols. Routine early iliac crest bone grafting is unnecessary. The prevalence of gait abnormality despite fracture union should be taken into account during the patient's rehabilitation. The extensive time missed from school and resulting scholastic setback should not be underestimated.
The Bridgeport Hospital Experience With Autologous Transfusion in Orthopedic Surgery

Published: April 2021

ABSTRACT
The transfusion records of 341 orthopedic patients who donated blood preoperative^ in the years 1992 and 1993 were audited to review the transfusion practices associated with the surgical procedures. The study sample underwent 182 total knee (TKA), 123 total hip (THA) arthroplasties, and 33 laminectomies with fusion (IAM) and 3 without. Data used were age, gender, predonation hemoglobin concentration (Hbd), initial (Hb1) and final (Hbf) hemoglobin concentration, surgical procedure, surgical blood order (SBO), and estimated blood loss (EBL). We analyzed for means and associations and differences between covariates. The means of EBL (mL), transfused units, donated units, Hb, (g/dL), Hbd, and Hbf (g/dL) for the most common procedures were: TKA- 272, 1.1, 2.1, 10.4, 13.9, and 10.1; THA951, 2.3, 2.4, 9.4, 13.8, and 9.9; and LAM- 589, 1.5, 2.2, 12.0, 14.6, and 1 1 .2. Phlebotomies for procedures with minimal blood loss, as for total knee arthroplasties, result in wastage. Autodonation under such circumstances takes patients to an unnecessary low hemoglobin concentration prior to either retransfusing the blood taken or discarding part of it. The number of preoperative autologous units donated can be reduced if predonation hemoglobin concentration is >15 g/dL and expected blood loss is not >2 g.
Placement of Screws in the Uncemented Acetabulum: Anatomic Analysis of the Danger Zone

Published: April 2021

ABSTRACT
Six cadavers were used to define the projection of the external iliac artery on the inner table of the acetabulum, and to quantitatively determine bony dimensions of the danger zone with regard to screw placement. The results showed that the majority of projections of the external iliac arteries were located on the superior portion of the posterosuperior quadrant and extended to the mid-superior portion of the anterosuperior quadrant (danger zone). The inferior portion of the danger zone was relatively far from the external iliac artery. The greatest depths of bone were found in the inferior portion of the danger zone, and the depths of bone in the middle and superior portion of the danger zone were relatively thinner. This anatomic study showed that the real danger zone was found in the middle and superior portions of the anterosuperior quadrant of the acetabulum. The inferior portion of the anterosuperior quadrant was relatively safer. This area may be considered if transacetabular screw placement in the anterosuperior quadrant is required.
