Interpretation of borehole gravity data of the Lalor volcanogenic massive sulfide deposit, Snow Lake, Manitoba, Canada
Authors: Schetselaar Ernst , Shamsipour Pejman 
Published: June 2015

We have acquired borehole gravity data along five drillholes intersecting the Lalor volcanogenic massive sulfide deposit hosted in the eastern Flin Flon greenstone belt at Snow Lake, Manitoba, Canada. Inverted apparent interval density (IAID) logs were calculated from the borehole gravity data and compared with lithofacies and [Formula: see text] logs; the latter of which is a geochemical proxy for differentiating volcanic rocks of felsic to mafic composition. The IAID anomalies predominantly reflect alternating mafic and felsic volcanic rock units in the footwall and hanging wall of the massive sulfide deposit. IAID lows are associated with [Formula: see text] highs that correspond to rhyolite and rhyodacite intervals in the hanging wall. IAID lows with associated [Formula: see text] peaks in the footwall occur within intervals of gneiss and schist formed by metamorphism of hydrothermally altered rocks, suggesting that these IAID lows still reflect the felsic composition of their volcanic protoliths. A significant peak-to-peak Bouguer anomaly of 0.66 mGal caused by an estimated excess mass of 0.7 mT can be correlated with gamma-gamma density signature of the main sulfide ore zone in three boreholes. This anomaly is aligned with the ore zone after restoring the displacement along a northeast-dipping structure. When integrated with drillhole lithology and lithogeochemistry logs, gravity borehole data can, in addition to the direct detection of mineralization, be used as a subsurface geological mapping tool.

Authors: Sakaan Sami , Ulrich Dagny , Luo Jenny , Finch Christopher K. , Self Timothy H. 
Published: June 2015

Background Hospitalized patients with chronic obstructive pulmonary disease (COPD) or asthma routinely have inhaled medications ordered for acute and maintenance therapy. Treatment may be administered via metered-dose inhaler (MDI) or dry-powder inhaler (DPI). These products must be appropriately labeled to be released home with the patient or discarded before discharge. Objective To assess the amount and estimated cost of wasted doses of medications via MDI or DPI for hospitalized patients with COPD/asthma. Methods A retrospective study was conducted at a university-affiliated hospital. Patients admitted between January 2011 and June 2012 with a primary diagnosis of COPD or COPD with asthma and who were ≥40 years of age were included. Information collected included use of albuterol, ipratropium, inhaled corticosteroids, long-acting beta agonist, or tiotropium and whether treatments were given by nebulizer, MDI, MDI plus valved holding chamber (VHC), or DPI. The number of doses dispensed, as well as doses not used, via MDI, MDI + VHC, or DPI were collected from electronic medical records. Costs associated with wasted medications were evaluated. Results Of 555 patient admissions screened, 478 (mean age, 66 years; 58% women; 74% African American) met study criteria. Of the total MDI or DPI doses dispensed, 87% were wasted, and associated hospital cost was approximately $86,973. Conclusions Substantial waste of inhaled medications was found in our study. Practical strategies are needed to reduce wasted inhalers. Further assessment of this problem is needed in other US hospitals.

Objective To present a case report and literature review of phenytoin-induced purple glove syndrome (PGS). Case summary A 54-year-old African American male presented to our hospital's emergency department (ED) following a seizure episode, cardiac arrest, and loss of consciousness. On arrival to the ED, the patient's total phenytoin level was subtherapeutic at 4.1 mcg/mL and his corrected total phenytoin level was subtherapeutic at 5.1 mcg/mL. In the ED, the patient received a loading dose of intravenous (IV) phenytoin 1,000 mg once via the left cephalic vein, at a rate of 50 mg/min, and was admitted to the medicine service. A day following IV phenytoin administration, a nurse noticed an IV fluid infiltration on the skin tissue around the left cephalic vein. The area appeared dark blue and purple in color, swollen, erythematous, and warm to touch. An ultrasound of the left upper extremity was performed and revealed subcutaneous fluid collection without evidence of thrombosis. Discussion The Naranjo Adverse Drug Reaction Probability Scale assigned a score of 7, indicating phenytoin as the probable cause of purple glove syndrome (PGS). The patient's PGS was managed with a combination of dry dressing material, left forearm elevation, collagenase topical cream, 0.1% IV bupivacaine, and IV fentanyl. The patient's injury was resolving at the time of discharge to a rehabilitation facility. Conclusion PGS is a rare complication of IV phenytoin therapy. The risk of PGS for this patient may have been abated by decreasing the phenytoin infusion rate from 50 mg/min to less than 25 mg/min.

Authors: Tofolean Doina , Adam Tatiana , Mazilu Laura , Parepa Irinel-Raluca 
Published: June 2015

Abstract
The present authors report the case of an adult male with no medical history, who developed prolonged fever of unknown cause, progression of anemia and lung fibrosis. A hematological disease was suspected and further investigations were done. The bone marrow aspirate raised the suspicion of Gaucher’s disease. The positive diagnosis was Gaucher’s disease with lung involvement (pulmonary fibrosis and pulmonary hypertension), and cardiac involvement (restrictive cardiomyopathy). Clinical evolution was unfavorable, and the patient died of cardiorespiratory failure.
In conclusion, the present case report illustrates a late diagnosis of Gaucher’s disease with lung and cardiac involvement resulting in death in a short period
Drei Sonnen über Gelnhausen

Published: June 2015

AbstractWe know that Hermann I., the Landgrave of Thuringia, was one of Wolfram’s patrons. But when exactly and how long did the author stay at his court? In my paper, I present an overlooked allusion which Wolfram makes in his dawn song, ›Ez ist nu tac‹. Wolfram describes the intimacy between the lovers by saying, even if the sun were threefold the three suns could not divide the couple. This is not just a metaphor but a historical reference to a halo phenomenon seen over Gelnhausen on January 30
Hunc tercium conscripsi cum maximo labore occultandi

Published: June 2015

AbstractThis article presents a manuscript that significantly enriches the textual corpus of ›Helfta Mysticism‹ with a series of hitherto unknown writings. Aside from this, it contains what is by some distance the oldest copy of the ›Legatus divinae pietatis‹, in the form of a ›special edition‹ that consists of excerpts from the known text as well as new material. This is preceded by a prologue and a florilegium which is marked in an epilogue as Gertrude’s own work. We argue that the epilogue of the florilegium, the prologue and the ›special edition‹ itself were probably composed by ›Sister N of Helfta‹ herself. The article provides a full description of the manuscript (Ms 827), a breakdown of the new ›special edition‹ of the ›Legatus‹-text, and an edition, translation, and close reading of the prologue.

AbstractIn a patient, it is usually not macroscopically possible to estimate the non-viable volume induced by radiofrequency ablation (RFA) after the procedure. The purpose of this study was to use anSixty-four liver specimens cut from 16 bovine livers were ablated under constant simulated, close physiological conditions with target volumes set to 14.14 ml (3-cm lesion) and 65.45 ml (5-cm lesion). Four commercially available radiofrequency (RF) systems were tested (n=16 for each system; n=8 for 3 cm and n=8 for 5 cm). A T1-weighted turbo spin echo (TSE) sequence with inversion recovery and a proton-density (PD)-weighted TSE sequence were acquired in a 1.0-T open magnetic resonance imaging (MRI) system. After manual dissection, actual macroscopic ablation diameters were measured and volumes calculated. MR volumetry was performed using a semiautomatic software tool. To validate the correctness and feasibility of the volume formula in macroscopic measurements, MR multiplanar reformation diameter measurements with subsequent volume calculation and semiautomatic MR volumes were correlated.Semiautomatic MR volumetry yielded smaller volumes than manual measurement after dissection, irrespective of RF system used, target lesion size, and MR sequence. For the 3-cm lesion, only 43.3% (T1) and 41.5% (PD) of the entire necrosis are detectable. For the 5-cm lesion, only 40.8% (T1) and 37.2% (PD) are visualized in MRI directly after intervention. The correlation between semiautomatic MR volumes and calculated MR volumes was 0.888 for the T1-weighted sequence and 0.875 for the PD sequence.After correlation of semiautomatic MR volumes and calculated MR volumes, it seems reasonable to use the respective volume formula for macroscopic volume calculation.

The wall-crossing behavior
for Bridgeland’s stability conditions
on abelian and K3 surfaces
Authors: Minamide Hiroki , Yanagida Shintarou , Yoshioka Kōta 
Published: June 2015

Abstract
The wall-crossing behavior for Bridgeland’s stability conditions on the derived category of coherent sheaves on K3 or abelian surface is studied. We introduce two types of walls. One is called the wall for categories, where the t-structure encoded by stability condition is changed. The other is the wall for stabilities, where stable objects with prescribed Mukai vector may get destabilized.
Some fundamental properties of walls and chambers are studied, including the behavior under Fourier–Mukai transforms. A wall-crossing formula of the counting of stable objects will also be derived.
As an application, we will explain previous results on the birational maps induced by Fourier–Mukai transforms on abelian surfaces. These transformations turns out to coincide with crossing walls of certain property.
Lessons learned from the porcine CARPA model: constant and variable responses to different nanomedicines and administration protocols
Authors: Urbanics Rudolf , Bedőcs Péter , Szebeni János 
Published: June 2015

AbstractPigs provide a sensitive and quantitative animal model of complement (C) activation-related pseudoallergy (CARPA) caused by liposomes and a wide range of nanoparticulate drugs or drug nanocarriers (nanomedicines). The tetrad of symptoms (hemodynamic, hematological, laboratory and skin changes) that arise within minutes after i.v. injection of reactogenic nanomedicines (RNMs) are highly reproducible among different pigs but the presence, direction and relative severity of symptoms are very different with different RNMs and their administration schedule. Bolus administration of RNMs usually trigger pulmonary hypertension with or without various degrees of systemic hyper- or hypotension, tachy-or bradycardia, arrhythmia, blood cell and inflammatory mediator changes and skin rash. These reactions can be rapid or protracted, and fully tachyphylactic, semi-tachyphylactic or non-tachyphylactic. Slow infusion usually diminishes the reactions and/or entail delayed, protracted and less severe hemodynamic and other changes. The goal of this review is to present some technical details of the porcine CARPA model, point out its constant and variable parameters, show examples of different reactions, highlight the unique features and capabilities of the model and evaluate its utility in preclinical safety assessment. The information obtained in this model enables the understanding of the complex pathomechanism of CARPA involving simultaneous anaphylatoxin and inflammatory mediator actions at multiple sites in different organs.
Microencapsulation of diglycidyl 1,2-cyclohexanedicarboxylate by in situ polymerization: preparation and characterization
Authors: Wang Hai-Ping , Li Meng-Qiang , Guo Chang , Hu Si-Qian 
Published: June 2015

AbstractMicrocapsules containing a glycidyl ester-type epoxy resin were successfully synthesized by in situ polymerization, with poly(melamine-urea-formaldehyde) as the shell material and diglycidyl 1,2-cyclohexanedicarboxylate (DGCHD) as the core substance. Scanning electron microscopy was performed to investigate the surface morphology and shell wall thickness of the microcapsule. The fabrication, diameters and thermal decomposition behavior of the resultant microcapsules were studied by means of Fourier transform infrared spectroscopy, laser particle size analysis, and thermogravimetric analysis (TGA), respectively. Results indicated that the highest loading of DGCHD in the as-prepared microcapsules was about 89.1 wt.% and that the mean diameter of the capsules was in the range of 50–130 μm, which can be adjusted by changing the feeding mass ratio of the core/shell material and emulsifying rate, respectively. TGA results showed that the microencapsulated DGCHD degraded in two distinguishable stages.
Effect of c-BN Size and Content on the Self-Propagating High-Temperature Synthesis of c-BN Composites Bonded with Ti-Al-C System Multiphase Products
Authors: Liang Baoyan , Wang Zhiwei , Zhang Yanli 
Published: June 2015

AbstractA mixture of Ti, Al, graphite and c-BN powders was used as raw material to fabricate Ti2AlC matrix-bonded c-BN composite using the self-propagating high-temperature synthesis (SHS) method. The effect of c-BN size and content on the fabrication of the composites was investigated. The results show that Ti2AlC matrix-bonded c-BN composites can be obtained by SHS. c-BN content and size evidently affected the phase composition and microstructure characteristic of the composites. At 10–30% c-BN (120/140 mesh) content, the product phases were Ti2AlC, Ti3AlC2, Al3Ti, TiN, TiC, AlN, graphite and TiB2. A dense transition layer with a thickness of about 10 µm showed the interface between c-BN and the matrix. However, Al peaks appeared, and the titanium aluminium carbide peak became weak in the samples containing 40% and 50% c-BN. c-BN was unequally enwrapped by one coating with a thickness of about 2 µm. The main product phases of the samples were Ti2AlC, Ti3AlC2, Al3Ti, TiN, TiC, AlN, graphite and TiB2 in the products with different c-BN sizes. The addition of coarse c-BN particles (80/100, 120/140 and 170/200 mesh) yielded a transition layer with a thickness of approximately 10 µm on the interface and Ti2AlC main phase matrix. The finer the particle size, the greater the reaction activity. When c-BN was finer (20 μm), c-BN more easily reacted with Ti and Al to form TiN, AlN and TiB2. The synthesis of Ti2AlC was obviously inhibited.
Transition Metal Nitrides: A First Principles Study
Authors: Pathak Ashish , Singh A. K. 
Published: June 2015

AbstractThe present work describes the structural stability and electronic and mechanical properties of transition metal nitrides (TmNs: B1 cubic structure (cF8, Fm$$\overline 3 $$m)) using first principles density functional theory (DFT) within generalized gradient approximation (GGA). The lattice constant of TmNs increases with increasing the atomic radii of the transition metals. Stability of the TmNs decreases from IVB to VIB groups due to increase in formation energy/atom. The bonding characteristics of these nitrides have been explained based on electronic density of states and charge density. All the TmNs satisfy Born stability criteria in terms of elastic constants except CrN and MoN that do not exist in equilibrium binary phase diagrams. The groups IVB and V–VIB nitrides are associated with brittle and ductile behaviour based on G/B ratios, respectively. The estimated melting temperatures of these nitrides exhibit reasonably good agreement with calculated with B than those of theC11for all nitrides.
Becoming an English language teacher: Continuities and Discontinuities
Authors: Werbińska Dorota 
Published: June 2015

Abstract
The aim of the paper is to report a three-year phenomenographic study conducted on seven EFL Polish teachers with the focus on presenting how they experience different aspects of language teaching at three crucial stages: 1) the time of ELT theory studying, 2) the time of school placement, 3) the time of first-year working as professional teachers. Each stage of the study is presented from the perspective of affordances standing for the respondents’ expectations (continuities) as well as constraints (discontinuities). The article concludes that discontinuities, rather than continuities, can prove invaluable in language teacher identity development.

Published: June 2015

Abstract
The paper discusses the role of e-portfolio in the development of reflective thinking in a group of pre-service English as a foreign language teachers. It stresses the benefits it can bring (e.g. autonomous learning, cooperative learning - the author highlights the social context of e-portfolio) as well as presents the threats and risks it might bring based on the own experience of the author. The results of this case study showed that the process of e-portfolio building can enhance professional development, self-confidence and the ability to self-reflect own work and progress. The author indicates also the possibilities of its use not only in the groups of pre-service teacher trainers but also in the groups of in-service teachers.
Library and school partnership on the move - a study of second language learners’ early literacy development
Authors: Damber Ulla 
Published: June 2015

Abstract
A study of eight multicultural suburban Swedish classes forms the backdrop of an analysis of the role of the library in students’ development towards becoming skilled readers. In-depth interviews with five teachers and one librarian involved in the classes provide empirical data, even though background information was collected with mixed research methods. The librarian’s narrative is the primary source of data in this article. The children′s educational trajectory from the preschool class to third grade is in focus. The present meta-analysis highlights the role of the library and the librarian, with respect to linkages made to the children’s overall literacy development. As a tool for analysis critical literacy theory was used, thus extending the influence of the librarian′s participation beyond the actual literacy practice, to the surrounding society. The results indicate that the library played a vital role in several ways, for teachers and students as well as for the parents. The collaboration between the librarian and the teachers started with the librarian having book talks with the children. However, she became a participant in the team’s planning and follow-up activities, linking the worlds in and out of school.
A comparative self-assessment of difficulty in learning English and German among Sudanese students
Authors: Ishag Adil , Altmayer Claus , Witruk Evelin 
Published: June 2015

Abstract
It is generally assumed that self-assessment plays a profound role in autonomous language learning and, accordingly, leads to learner independency. It encourages learners to prospect their own language learning processes and provides them with feedback of their learning progress. Self-assessment also raises the awareness of learners’ individual needs among both students and teachers alike and will therefore contribute to the development of the whole learning process.
The purpose of the current study is to explore and compare – through self-assessment – the level of perceived difficulty of the overall foreign language learning and language skills among Sudanese students enrolled at the English and German language departments respectively, at the University of Khartoum in Sudan. A representative sample composed of 221 students from the two departments have been asked to self-evaluate and rate the overall language difficulty and areas of difficulty in language skills, as well as their own language proficiency.
The results indicate that German language is relatively rated as a difficult language in comparison to the English language and that German grammar was also rated as more difficult. However, students rated the pronunciation and spelling of German language as easier than in English language. Concerning the language skills, reading and speaking skills were reported as more difficult in German, whereas writing and listening tend to be easier than in English. Finally, students’ academic achievements have been self-reported.
