Wind Erosion and PM10 Emissions from No‐Tillage Cropping Systems in the Pacific Northwest
Authors: Sharratt Brenton , Young Frank , Feng Gary 
Published: May 2017

Core Ideas
Erosion of agricultural lands affect air quality in the Inland Pacific Northwest.
Alternatives to tillage‐based cropping systems are needed to reduce wind erosion.
No‐tillage cereal cropping systems reduce wind erosion and particulates ≤10 µm in diameter emissions.
Economically viable strategies are sought for no‐tillage cropping systems.
Wind erosion is a concern in the Inland Pacific Northwest (PNW) of the United States where the emission of particulates ≤10 µm in diameter (PM10) from winter wheat (Triticum aestivum L.)/summer fallow (WW/SF) dryland cropping systems during high winds degrades air quality. There is a potential to reduce the risk of wind erosion using no‐tillage or chemical fallow cropping systems, but wind erosion observations are lacking from these systems. We measured sediment and PM10 flux from reduced‐tillage WW/SF, no‐tillage wheat/chemical fallow (NTW/CF), and no‐tillage spring barley (Hordeum vulgare L.)/spring wheat (NTSB/SW) using a portable wind tunnel near Ralston, WA. Horizontal sediment flux, wind speed, and PM10 concentration were measured over two consecutive 10 min sampling periods inside the tunnel after sowing wheat in spring or late summer on four replications of the rotations. Sediment flux was measured with a modified Bagnold type sampler while wind speed and PM10 concentration were respectively measured with pitot tubes and aerosol monitors positioned at six heights above the soil surface inside the tunnel. Sediment and PM10 fluxes were an order of magnitude greater in late summer than spring. After sowing wheat in spring, sediment and PM10 fluxes were greater for the NTSB/SW than NTW/CF rotation while, after sowing winter wheat in late summer, sediment and PM10 fluxes were greater for the WW/SF than the NTSB/SW rotation. Our results suggest that wind erosion and PM10 emissions can be significantly reduced using no tillage cropping systems in the PNW.

Objective: This study focused on the extraction of bioactive constituents in Iraqi cultivated Artemisia dracunculus L dried aerial parts and phytochemical screening with qualitative estimation of three important flavonols (kampferol, quercetin and rutin). The study also included evaluating the antitumor effects (skin cancer) of methanolic extract for this plant.Methods: Extraction of bioactive constituents was carried out according to standard protocols using 85% methanol. The phytochemical screening has been done using chemical tests and GC/MS with qualitative estimation of three flavonols (kampferol, quercetin and rutin) utilized preparative high-performance liquid chromatography (PHPLC). Skin cancer in mice was induced by using 7, 12-dimethylbenze (a) anthracene to evaluate the antitumor effect of methanolic extract of Artemisia dracunculus when administered orally via intragastric feeding tube. Body weight, tumor volume, tumor burden, percent of tumor incidence and histopathological examination were measured in all tested animals.Results: Phytochemical screening revealed the presence of glycosides, volatile oils, alkaloids, tannin, terpenoids, phenolic compounds and flavonoids. The preparative high-performance liquid chromatography (PHPLC) analysis indicated that rutin had the highest concentration followed by quercetin while kampferol had the lowest concentration. The methanolic extract of the Artemisia dracunculus significantly reduced the percent of tumor incidence, tumor volume and tumor burden of skin cancer in mice (p<0.05).Conclusion: Dried aerial parts of Iraqi Artemisia dracunculus contain many bioactive constituents including three flavonoid compounds (quercetin, kampferol and rutin) that may be responsible for chemo preventive effect exerting by methanolic extract of Artemisia dracunculus against 7, 12-dimethylbenzeanthracine-induced skin cancer in mice.

OBJECTIVEInterbody fusion cages are widely used to achieve initial fixation and secure spinal fusion; however, there are certain technique-related complications. Although anterior cage dislodgement can cause major vascular injury, the incidence is extremely rare. Here, the authors performed a review of anterior cage dislodgement following posterior lumbar interbody fusion (PLIF) surgery.METHODSThe authors retrospectively reviewed the cases of 4625 patients who had undergone PLIF at 6 institutions between December 2007 and March 2015. They investigated the incidence and causes of surgery-related anterior cage dislodgement, salvage mechanisms, and postoperative courses.RESULTSAnterior cage dislodgement occurred in 12 cases (0.26%), all of which were caused by technical errors. In 9 cases, excessive cage impaction resulted in dislodgement. In 2 cases, when the cage on the ipsilateral side was inserted, it interacted and pushed out the other cage on the opposite side. In 1 case, the cage was positioned in an extreme lateral and anterior part of the intervertebral disc space, and it postoperatively dislodged. In 3 cases, the cage was removed in the same operative field. In the remaining 9 cases, CT angiography was performed postoperatively to assess the relationship between the dislodged cage and large vessels. Dislodged cages were conservatively observed in 2 cases. In 7 cases, the cage was removed because it was touching or compressing large vessels, and an additional anterior approach was selected. In 2 patients, there was significant bleeding from an injured inferior vena cava. There were no further complications or sequelae associated with the dislodged cages during the follow-up period.CONCLUSIONSAlthough rare, iatrogenic anterior cage dislodgement following a PLIF can occur. The authors found that technical errors made by experienced spine surgeons were the main causes of this complication. To prevent dislodgement, the surgeon should be cautious when inserting the cage, avoiding excessive cage impaction and ensuring cage control. Once dislodgement occurs, the surgeons must immediately address this difficult complication. First, the possibility of a large vessel injury should be considered. If the patient’s vital signs are stable, the surgeon should continue with the surgery without cage removal and perform CT angiography postoperatively to assess the cage location. Blind maneuvers should be avoided when the surgical site cannot be clearly viewed. When the cage compresses or touches the aortic artery or vena cava, it is better to remove the cage to avoid late-onset injury to major vessels. When the cage does not compress or touch vessels, its removal is controversial. The risk factors associated with performing another surgery should be evaluated on a case-by-case basis.
Pediatric meningiomas: 65-year experience at a single institution
Authors: Grossbach Andrew J. , Mahaney Kelly B. , Menezes Arnold H. 
Published: May 2017

OBJECTIVEMeningiomas are relatively common, typically benign neoplasms in adults; however, they are relatively rare in the pediatric population. Pediatric meningiomas behave very differently from their adult counterparts, tending to have more malignant histological subtypes and recur more frequently. The authors of this paper investigate the risk factors, pathological subtypes, and recurrence rates of pediatric meningiomas.METHODSA retrospective chart review was conducted at the University of Iowa to identify patients 20 years old and younger with meningiomas in the period from 1948 to 2015.RESULTSSixty-seven meningiomas in 39 patients were identified. Eight patients had neurofibromatosis, 2 had a family history of meningioma, and 3 had prior radiation exposure. Twelve (31%) of the 39 patients had WHO Grade II or III lesions, and 15 (38%) had recurrent lesions after resection.CONCLUSIONSPediatric meningiomas should be considered for early treatment and diligent follow-up.

Published: May 2017

SummaryObjectives: The aim of the study was to describe the differences in pelvic limb alignment between healthy purebred English Bulldogs and those with medial patellar luxation through the measurement of femoral and tibial angles on computed tomography images in multiplanar reconstruction modality (MPRCT).Methods: Twenty-one purebred English Bulldogs were included and divided into two groups: one including healthy dogs (15 limbs) and the other including those with medial patellar luxation (24 limbs). Three different observers used MPR-CT to measure the following angles: anatomical lateral proximal femoral angle (aLPFA), anatomical lateral distal femoral angle (aLDFA), mechanical lateral proximal femoral angle (mLPFA), mechanical lateral distal femoral angle (mLDFA), angle of inclination of the femoral neck (AI), angle of anteversion (AA), mechanical medial proximal tibial angle (mMPTA), mechanical medial distal tibial angle (mMDTA), mechanical caudal distal tibial angle (mCdDTA), mechanical caudal proximal tibial angle (mCdPTA), and the tibial torsion angle (TTA). A Mann-Whitney U test was used to compare each variable in both groups.Results: The values for aLDFA and mLDFA in the medial patellar luxation population were significantly increased compared to healthy subjects (p <0.05). No significant differences were observed for the other variables.Clinical significance: In our population, an increased distal femoral varus was associated with medial patellar luxation. Our results could be useful to determine whether or not angular deformity of the femur is present and help determine the degree of correction necessary to restore alignment.ORCID iD:FMM: http://orcid.org/0000-0001-9615-2540
Nietzsche, lecteur de Pascal : « le seul chrétien logique »
Authors: Lebreton Lucie 
Published: May 2017

L’importance de la figure de Pascal dans la pensée de Nietzsche ressort de la formule qu’il lui consacre, celle de « chrétien logique ». Pascal incarne selon lui le conflit entre le christianisme et la morale qui en est issue, donc entre la foi chrétienne et la probité scientifique, liées entre elles par l’idée que Dieu est vérité, que la vérité est divine. Parce qu’il considère sa pensée comme une manière, pour le christianisme, de se surmonter lui-même, Nietzsche n’hésite pas à voir en Pascal l’un de ses précurseurs.
Groupes d’analyse de pratiques pour enseignants. Mise en perspective de trois dispositifs inspirés du « groupe Balint »
Authors: Dubois Arnaud , Lerner-Seï Sophie , Blanchard-Laville Claudine 
Published: May 2017

Les auteurs, tous trois impliqués dans l’animation de groupes d’analyse clinique de pratiques professionnelles auprès d’enseignants, proposent de mettre en perspective trois dispositifs conçus par Jacques Lévine, Francis Imbert et Claudine Blanchard-Laville pour lesquels l’influence des travaux de Michael Balint a été prépondérante. Comment, à partir de cet ancrage commun référé à la psychanalyse, ces cliniciens ont-ils élaboré leur propre dispositif d’analyse de pratiques ? En quoi sont-ils proches ou éloignés ? Après avoir retracé brièvement l’émergence des premiers groupes Balint dans le champ de l’enseignement et de la formation, les auteurs s’arrêtent sur chacun de ces trois dispositifs dans lesquels ils analysent successivement l’objet du travail, le déroulement des séances, les références théoriques mobilisées par les animateurs et leur rapport à l’institution. Prenant appui sur un matériel constitué d’articles, de témoignages, d’extraits de séances retranscrites, ils mettent en exergue ce qui fait la singularité de ces trois démarches qu’ils relient à la formation, au parcours professionnel et aux références théoriques de leurs initiateurs.
De la mémoire trouée à la parentalité empêchée : clinique de la transmission psychique après un génocide
Authors: Veuillet-Combier Claudine , Katz-Gilbert Muriel 
Published: May 2017

Il est proposé de réfléchir à la question du génocide et ses effets inconscients sur le projet de parentalité des survivants et leurs descendants, en termes de transmission psychique à travers les générations. En illustration est présentée la situation de rencontre avec madame B, dont le passé ancestral est marqué par la Shoah, avec la libre réalisation de son arbre généalogique comme outil clinique de recherche. Ce qui est souligné alors, c’est comment la trace de l’expérience traumatique logée dans le silence des mots peut venir livrer un héritage traumatique bloquant l’accès au devenir parent.
EPN-Repro2: A reference GNSS tropospheric data set over Europe

Published: May 2017

Abstract. The present availability of 18+ years of GNSS data belonging to the EUREF Permanent Network (EPN, http://www.epncb.oma.be/) is a valuable database for the development of a climate data record of GNSS tropospheric products over Europe. This data record can be used as a reference for a variety of scientific applications (e.g. validation of regional numerical weather prediction reanalyses and climate model simulations) and has a high potential for monitoring trends and the variability in atmospheric water vapour. In the framework of the EPN-Repro2, the second reprocessing campaign of the EPN, five Analysis Centres homogenously reprocessed the EPN network for the period 1996–2014. A huge effort has been made to provide solutions that are the basis for deriving new coordinates, velocities and tropospheric parameters for the entire EPN. The individual contributions are then combined to provide the official EPN reprocessed products. This paper is focused on the EPN-Repro2 tropospheric product. The combined product is described along with its evaluation against radiosonde data and European Centre for Medium-Range Weather Forecasts (ECMWF) reanalysis (ERA-Interim) data.

AbstractThe Traverse Gravimeter Experiment (TGE) from the Apollo 17 mission was the first and only successful gravity survey on the surface of the Moon, revealing the local gravity field at Taurus‐Littrow Valley (TLV). TLV is hypothesized to be a basalt‐filled graben, oriented radial to Serenitatis basin. We implemented modern 3‐D modeling techniques using recent high‐resolution Lunar Reconnaisance Orbiter topography and image data sets to reinvestigate the subsurface structure of TLV and constrain the volcanic and tectonic history of the region. Updated topography led to significant improvements in the accuracy of free‐air, Bouguer, and terrain corrections. To determine the underlying geometry for TLV, we tested a range of possible thicknesses, dips, and wall positions for the graben fill. We found that the thickness and position previously determined by Talwani et al. (1973) represent our preferred model for the data, but with walls with dips of 30°, rather than 90°. We found large model misfits due to unmodeled 3‐D structure and density anomalies, as well as parameter trade‐offs. We performed a sensitivity analysis to quantify the parameter trade‐offs in an ideal future survey, assuming dominantly 2‐D geological structure. At the TGE survey noise level (2.5 mGal), the fill thickness was constrained to ±150 m, the wall angle to
and the wall positions to ±1 km of the preferred model. This information can be used to inform the design of future lunar gravimetry experiments in regions similar to TLV.
Adaptive harmonic steady‐state control for rejection of sinusoidal disturbances acting on a completely unknown system
Authors: Kamaldar Mohammadreza , Hoagg Jesse B. 
Published: May 2017

SummaryThis paper presents an adaptive harmonic steady‐state (AHSS) controller that addresses the problem of rejecting sinusoids with known frequencies that act on a completely unknown asymptotically stable linear time‐invariant system. We analyze the stability and closed‐loop performance of AHSS for multi‐input multi‐output systems that are square (ie, the number of controls equals the number of performance measurements). In this case, we show that AHSS asymptotically rejects disturbances, that is, the performance measurement tends to 0. We also present a numerical study of the steady‐state and transient performance of AHSS for square and nonsquare systems.
