Stratigraphic correlation potential of magnetic susceptibility and gamma-ray spectrometric variations in calciturbiditic facies (Silurian-Devonian boundary, Prague Synclinorium, Czech Republic)Magnetic susceptibility (MS) and gamma-ray spectrometry (GRS) stratigraphy were used for correlation and characterization of eight Silurian-Devonian (S-D) sections in the Prague Synclinorium (Czech Republic). They represent two different facies developments: lower subtidal to upper slope deposits and slope-to-basin-floor distal calciturbidites. Sections from relatively shallow- and deep-water sections are easy to compare and correlate separately, although the detailed relationship between these two facies is still not entirely clear and correlations between the two settings are difficult. This may be due to sharp facies transitions and presence of stratigraphic gaps. The MS and GRS stratigraphic variations combined with sedimentologic data have been also used for reconstruction of the evolution of the sedimentary environment. The beds close above the S-D boundary show noticeably enhanced MS magnitudes but weak natural gamma-ray emissions. It may correspond to an increased amount of terrigenous magnetic material occurring with short-term shallowing (sedimentological evidence). In deep-water sections the uppermost Silurian is characterized by high MS and GRS values. It corresponds to a supply of recycled sediment to the lower wedge which occurred during the late Pridoli regression phase. The basal Devonian beds correspond to gradual deepening, but the overlying sequences reflect other shallowing episodes which are expressed in increasing MS and gamma ray activity of rocks. The MS and GRS fluctuations are interpreted as a result of local subsidence of the sea bottom along synsedimentary growth-faults and/or a biotic event rather than of eustatic sea-level changes.

Microfacies analysis of the Upper Triassic (Norian) "Bača Dolomite": early evolution of the western Slovenian Basin (eastern Southern Alps, western Slovenia)The Slovenian Basin represents a Mesozoic deep-water sedimentary environment, situated on the southern Tethyan passive margin. Little is known about its earliest history, from the initial opening in the Carnian (probably Ladinian) to a marked deepening at the beginning of the Jurassic. The bulk of the sediment deposited during this period is represented by the Norian-Rhaetian "Bača Dolomite", which has, until now, been poorly investigated due to a late-diagenetic dolomitization. The Mount Slatnik section (south-eastern Julian Alps, western Slovenia) is one of a few sections where the dolomitization was incomplete. Detailed analysis of this section allowed us to recognize eight microfacies (MF): MF 1 (calcilutite), MF 2 (pelagic bivalve-radiolarian floatstone/wackestone to rudstone/packstone), MF 3 (dolomitized mudstone) with sub-types MF 3-LamB and MF 3-LamD (laminated mudstone found in a breccia matrix and laminated mudstone found in thin-bedded dolomites, respectively) and MF 3-Mix (mixed mudstone), MF 4 (bioturbated radiolarian-spiculite wackestone), MF 5 (fine peloidal-bioclastic packstone), MF 6 (very fine peloidal packstone), MF 7 (bioclastic wackestone) and MF 8 (crystalline dolomite). The microfacies and facies associations indicate a carbonate slope apron depositional environment with hemipelagic sedimentation punctuated by depositions from turbidites and slumps. In addition to the sedimentary environment, two "retrogradation-progradation" cycles were recognized, each with a shift of the depositional setting from an inner apron to a basin plain environment.

Geology of the Čoka structure in northern Banat (Central Paratethys, Serbia)The Čoka structure is a fault-bounded anticline in northern Banat, in the southern part of the Neogene Pannonian Basin. The structure and its vicinity were explored by 24 wells. In addition to well logs, paleontological, sedimentological and petrological analyses of cores and 27 seismic sections with different parameters of acquisition and processing were used for geological investigation of the area. The E-SE dipping pre-Neogene basement consists of Lower Triassic clastics and, in the NW part of the study area, Paleozoic greenschists. Thin Middle Miocene (Badenian) sediments unconformably overlie the basement and pinch out towards the elevated NW part of the study area. They are also missing in some wells on the apex of the Čoka structure, probably due to erosion. Badenian sediments were deposited in a shallow marine environment. The late Middle Miocene (Sarmatian) strata are missing and the Badenian is directly overlain by Upper Miocene (Pannonian) sediments. The latter also pinch out towards the NW but in contrast to Badenian sediments, they are present in all boreholes on the Čoka structure. Pannonian deposition took place in a caspibrackish environment of Lake Pannon, with predominance of marls and fine-grained clastics. Pannonian sediments are conformably overlain by latest Miocene (Pontian) and Pleistocene lacustrine, alluvial and terrestrial sediments.

Unusual Intramuscular Lipoma of Deltoid MuscleLipomas are common soft tissue tumors usually located under the skin. Nevertheless, intramuscular lipomas of deltoid muscle are unusual tumors. We present a case of 74 years old woman with an intramuscular like clepsydra lipoma of deltoid muscle. The lesion was a palpable soft mass at the lateral side of the humerus. The patient had no previous history of trauma. The main symptom was pain only in abduction and extension. Imaging, pathological findings and surgical excision are discussed.
Le deuil des grands métiers
Authors: Zunigo Xavier 
Published: August 2010

Résumé La notion de « projet professionnel » s’est imposée comme une catégorie centrale de l’action publique en matière de lutte contre le chômage des jeunes de moins de 26 ans. Mais la question de sa transposition pratique se pose dans la conduite au quotidien de l’action publique. La vision rationnelle et téléologique du devenir social qu’elle sous-tend s’oppose, en effet, aux représentations à court terme de l’avenir qui sont celles des jeunes les plus dépossédés sur le marché du travail. L’enquête ethnographique menée dans une institution de gestion du chômage dont le rôle est d’aider les stagiaires à formuler un « projet professionnel » voudrait montrer que la notion subit progressivement une adaptation réaliste. La succession des échecs dans les recherches de stages, de formations ou d’emplois oblige les stagiaires à se porter vers des emplois qu’ils auraient été plus réticents à accepter en début de formation (caissière, manœuvre, manutentionnaire, etc.). Loin d’offrir les moyens d’une projection dans l’avenir, la formation prend ainsi la forme d’une expérience, sous assistance institutionnelle, des potentialités limitées des ressources détenues par les stagiaires et d’une confirmation d’un futur étroitement borné aux zones les plus dominées de l’espace social.
Les néo-enseignants face à l'utilitarisme
Authors: Geay Bertrand 
Published: August 2010

Résumé Évoquer la « montée de l’individualisme » ou l’existence d’un nouveau système normatif, fondé sur l’appel à l’autonomie et le travail en réseau, n’est guère convaincant pour comprendre les transformations de l’univers professionnel enseignant, où existent de longue date des formes spécifiques d’individualisme et des traditions pédagogiques centrées sur la valorisation de l’autonomie personnelle. Pour rendre compte des spécificités de cet univers et des transformations qui l’affectent actuellement, on analyse ici ce qui se joue au moment où de nouveaux venus entrent dans la profession, à partir des résultats d’une enquête par questionnaire croisant des éléments relatifs aux trajectoires des néo-enseignants, à leurs premières expériences du métier et aux représentations qu’ils se forment de leur avenir personnel et professionnel. On met ainsi à jour une forme spécifique d’individualisme qui relève davantage d’un certain relativisme politico-institutionnel et d’une sorte de primat accordé à la sphère professionnelle immédiate ou à la sphère privée, plutôt que d’une conception proprement utilitariste. Ce rapport à soi-même et aux autres peut tout aussi bien jouer comme forme de résistance aux injonctions institutionnelles que comme entrave à l’organisation collective.
Scleral Fixation of Intraocular Lens in Eyes With History of Open Globe Injury
Authors: Banaee Touka , Sagheb Setareh 
Published: August 2010

Purpose:
To report the results and complications of scleral fixation of intraocular lens (SF-IOL) in traumatized eyes of children with iris defects and inadequate capsular support with technique customized to the condition of the eye.

Methods:
Retrospective review of pediatric eyes with a history of open globe injury and SF-IOLs. All eyes had undergone pars plana vitrectomy and lensectomy after primary repair of the laceration. Site of scleral fixation and limbal incision were selected according to the site of traumatic scar, remaining capsular support, and keratometry.

Results:
Ten patients with a mean age of 6.1 years were included. Mean duration of aphakia was 18.7 months. Five eyes had adequate capsular support for one haptic of the IOL. The only intraoperative complication was mild ciliary body hemorrhage. Mean follow-up was 11.8 months. Uncorrected visual acuity did not improve postoperatively in only one eye due to severe corneal astigmatism. Best-corrected visual acuity improved in 6 eyes. Mean postoperative sphere and cylinder were 1.8 and −3.05 diopters, respectively. The only postoperative complication was decentration of a sulcus-fixed haptic needing reoperation in one eye.

Conclusion:
SF-IOL is a viable option for correcting traumatic aphakia and can have good results if customized to the condition of the eye.

Purpose:To study the potential incidence of retinopathy in children with febrile seizures.Methods:Thirty-four children with febrile seizures, aged 3 months to 9 years and admitted from January 2000 to June 2008, were retrospectively analyzed. All cases received fundus examination within 24 hours after admission and the incidence of retinopathy was calculated.Results:None of the subjects was found to have retinal hemorrhages. Therefore, using Hanley’s Rule of Three, the upper limit of 95% confidence interval of retinal hemorrhages following febrile seizures in children is less than 10%.Conclusion:The incidence of retinal hemorrhages in children with febrile seizures is lower than 10%. If retinal hemorrhages are found in children with febrile seizures, other causes need to be considered.
Spontaneous Improvement of Channel Deposits Following Intacs Implantation
Authors: Kaufman Matthew B. , Dhaliwal Deepinder K. 
Published: August 2010

Purpose:
To report a case of filamentous crystalline channel deposits and stromal haze extending outside the channel, which continued to worsen more than 3 years after implantation before eventually improving without significant intervention.

Methods:
A 48-year-old woman presented for refractive surgery evaluation. Uncorrected visual acuity was 20/400 in both eyes. Ocular history was significant for mild blepharitis but was otherwise normal. Approximately 4 months after bilateral Intacs (KeraVision) implantation, the patient developed intrachannel deposits in both eyes, which had increased significantly at 3-year follow-up.

Results:
The intrachannel deposits and haze spontaneously improved, and 9 years following implantation few deposits and little haze remained.

Conclusions:
Channel deposits, opacification, and haze are widely reported complications following the implantation of intrastromal corneal ring segments. Such deposits and opacifications are generally not clinically significant and may resolve spontaneously.
Late Onset Secondary Cataract Following Implantation of an Iris-Fixated Phakic Intraocular Lens
Authors: Liu Anthony , Manche Edward E. 
Published: August 2010

Purpose:
To report a case of bilateral late onset anterior cortical cataract following implantation of an iris-fixated phakic intraocular lens (pIOL).

Methods:
Single observational case report.

Results:
Three and a half years following uncomplicated consecutive implantation of iris-fixated pIOL in both eyes, anterior cortical cataract changes inferiorly emanating from the site of enclavation of the lens in the right eye were noted. By 7 years after implantation, anterior cortical cataract changes were seen emanating from the enclavation sites superiorly and inferiorly in both eyes. These cataracts did not cause any loss of corrected distance visual acuity.

Conclusions:
This case demonstrates that a potential complication of an iris-fixated pIOL is late onset secondary cataract formation.
Notch1 Deficiency Results in Decreased Inflammation during Wound Healing and Regulates Vascular Endothelial Growth Factor Receptor-1 and Inflammatory Cytokine Expression in Macrophages
Authors: Hamilton Outtz Hasina , Wu June K. , Wang Xing , Kitajewski Jan 
Published: August 2010

Abstract
We investigated whether Notch signaling plays a role in regulating macrophage responses to inflammation. In a wound healing assay, macrophage recruitment was decreased in Notch1+/− mice, and the wounds were characterized by decreased TNF-α expression. As wound healing progressed, Notch1+/− wounds had increased vascularization and collagen deposition compared with wild-type wounds. In mice with myeloid-specific Notch1 deletion, wounds had decreased macrophage recruitment as well as decreased TNF-α expression, indicating the specific role of Notch1 in the inflammatory response in these cells. In vitro, we found that vascular endothelial growth factor receptor-1 (VEGFR-1) was upregulated in macrophages in response to LPS/IFN-γ and that this upregulation depended on Notch signaling. Furthermore, macrophages from Notch1+/− mice had decreased expression of VEGFR-1 compared with macrophages from wild-type mice, whereas VEGFR-1 expression in Notch4−/− macrophages was normal. Inhibition of Notch signaling decreased induction of the inflammatory cytokines IL-6, IL-12, CXCL10, MCP-1, monokine induced by IFN-γ, and TNF-α in macrophages in response to LPS/IFN-γ. Additionally, macrophages from Notch1+/− mice demonstrated decreased induction of IL-6, IL-12, and TNF-α in response to stimulation compared with wild-type mice. Thus, both pharmacological inhibition of Notch and genetic analysis demonstrate that Notch1 regulates VEGFR-1 and cytokine expression in macrophages. We have also established that Notch1 is important for the inflammatory response during wound healing in mice.

AbstractGiven a complex semisimple Lie algebra is a compact real form of g), let be the orthogonal projection (with respect to the Killing form) onto the Cartan subalgebra , where t is a maximal abelian subalgebra of . Given x ∈ g, we consider π(Ad(K)x), where K is the analytic subgroup G corresponding to , and show that it is star-shaped. The result extends a result of Tsing. We also consider the generalized numerical range f (Ad(K)x), where f is a linear functional on g. We establish the star-shapedness of f (Ad(K)x) for simple Lie algebras of type B.

Published: August 2010

AbstractMultilayer CVD coatings for high speed cutting applications were designed to achieve high wear and heat resistance during machining of steel alloys. In this work the microstructure and cutting performance of these novel multilayer CVD coatings are investigated and compared with standard CVD multilayer coatings. 3D‐FIB tomography is used to characterize the microstructure of the layers, especially the transition between the Ti(C,N) and the Al2O3 layer. The 3D reconstruction of the surface of the Ti(C,N) layer shows the formation of protruded Ti(C,N) grains with a very particular architecture, which penetrate into the Al2O3 top‐layer, providing a mechanical anchoring between both layers. Cemented carbides coated with the novel CVD multilayer present reduced crater and flank wear as well as improved adherence between the Al2O3 top‐layer and the Ti(C,N) layer leading to a dramatic improvement of cutting performance.

Published: August 2010

AbstractDespite the imminent commercial introduction of Li‐ion batteries in electric drive vehicles and their proposed use as enablers of smart grids based on renewable energy technologies, an intensive quest for new electrode materials that bring about improvements in energy density, cycle life, cost, and safety is still underway. This Progress Report highlights the recent developments and the future prospects of the use of phases that react through conversion reactions as both positive and negative electrode materials in Li‐ion batteries. By moving beyond classical intercalation reactions, a variety of low cost compounds with gravimetric specific capacities that are two‐to‐five times larger than those attained with currently used materials, such as graphite and LiCoO2, can be achieved. Nonetheless, several factors currently handicap the applicability of electrode materials entailing conversion reactions. These factors, together with the scientific breakthroughs that are necessary to fully assess the practicality of this concept, are reviewed in this report.
Local Electrochemical Functionality in Energy Storage Materials and Devices by Scanning Probe Microscopies: Status and Perspectives
Authors: Kalinin Sergei V. , Balke Nina 
Published: August 2010

AbstractEnergy storage and conversion systems are an integral component of emerging green technologies, including mobile electronic devices, automotive, and storage components of solar and wind energy economics. Despite the rapidly expanding manufacturing capabilities and wealth of phenomenological information on the macroscopic device behaviors, the microscopic mechanisms underpinning battery and fuel cell operations in the nanometer–micrometer range are virtually unknown. This lack of information is due to the dearth of experimental techniques capable of addressing elementary mechanisms involved in battery operation, including electronic and ion transport, vacancy injection, and interfacial reactions, on the nanometer scale. In this article, a brief overview of scanning probe microscopy (SPM) methods addressing nanoscale electrochemical functionalities is provided and compared with macroscopic electrochemical methods. Future applications of emergent SPM methods, including near field optical, electromechanical, microwave, and thermal probes and combined SPM‐(S)TEM (scanning transmission electron microscopy) methods in energy storage and conversion materials are discussed.
One‐Step Synthesis of Chiral Azamacrocycles via Palladium‐Catalyzed Enantioselective Amination of 1,5‐Dichloroanthraquinone and 1,5‐Dichloroanthracene
Authors: Ranyuk Elena R. , Averin Alexei D. , Beletskaya Irina P. 
Published: August 2010

AbstractAsymmetric amination of 1,5‐dichloroanthraquinone and 1,5‐dichloroanthracene with di‐ and trioxadiamines catalyzed by palladium complexes with various chiral phosphine ligands gave chiral macrocycles with ee values of up to 60%. The dependence of the chemical yields and enantiomeric excess on the nature of the starting compounds and the phosphine ligands employed was demonstrated. An unexpected spontaneous resolution upon crystallization of the macrocycle comprising anthraquinone and dioxadiamine moieties was observed while in the case of the macrocycle with a trioxadiamine linker racemic monocrystals were obtained. Crystallization of the enantiomerically enriched mixtures afforded chiral macrocycles with 88–99% ee.

Published: August 2010

AbstractThe bifunctional Cinchona‐based sulfonamide catalysts showed the highest levels of enantioselectivity reported to date in the alcoholytic desymmetrization of meso‐glutaric anhydrides. Density functional theory (DFT) computational studies provide detailed insight into the observed sense of enantioselectivity. Moreover, detailed experimental studies and single crystal X‐ray analysis confirmed that these bifunctional organocatalysts 3 do not form H‐bonded self‐aggregates in both solution and solid state. The synthetic utility of this methodology was also demonstrated in the synthesis of pharmaceutically important γ‐amino acids, such as (S)‐pregabalin. Of the many asymmetric syntheses of enantiomerically pure (S)‐pregabalin reported to date, our synthesis requires the least number of and the simplest steps.
