Uptake of Pb and Zn from a binary solution onto different fixed bed depths of natural zeolite – the BDST model approach
Authors: Nuić I. , Trgo M. , Perić J. , Vukojević Medvidović N. 
Published: June 2015

AbstractThe removal of lead and zinc from a binary solution by fixed bed depths (40, 80 and 120 mm) of a natural zeolite was examined at a flow rate of 1 mL/min. The results obtained were fitted to the Bed Depth Service Time (BDST) model and the parameters of the model (q and k) were used to design a column system for flow rates of 2 and 3 mL/min at a bed depth of 80 mm. The experimental results were in excellent agreement with those predicted and experimental breakthrough curves for the binary systems were obtained. This approach facilitates the design of effective binary column processes without additional experimentation. Two major design parameters, the Empty Bed Contact Time (EBCT) and the zeolite usage rate, were calculated. The highest EBCT value of 13.56 min represents the optimal conditions for the binary (Pb+Zn) solution.
Removal of chromium(VI) from aqueous solutions using zeolites modified with HDTMA and ODTMA surfactants
Authors: Szala Barbara , Bajda Tomasz , Jeleń Anna 
Published: June 2015

AbstractThe removal of Cr(VI) from aqueous solutions under various conditions was investigated using a natural clinoptilolite and a synthetic zeolite derived from fly-ash (Na-P1), modified either with hexadecyltrimethylammonium bromide (HDTMA) or octadecyltrimethylammonium bromide (ODTMA). The study was focused mainly on the impact of the properties of the zeolite on the sorption capacity, the sorption mechanism, the influence of pH and the durability of the immobilization. The zeolites were modified with HDTMA and ODTMA surfactants up to 100% and 120% of their external cation exchange capacity. Batch and column studies were conducted to evaluate the influence of pH and the initial Cr(VI) concentration on their efficiencies for removing chromates. The organo-zeolites show a significant ability to remove Cr(VI) from aqueous solutions. The amount of Cr(VI) removed by organo-clinoptilolite and organo-zeolite Na-P1 is greater at low pH values, whereas the sorption efficiency decreased with increasing pH. Sorption of Cr(VI) was more efficient with the HDTMA-modified organo-clinoptilolite (150 mmol Cr(VI)/kg) than the ODTMA-modified clinoptilolite (132 mmol Cr(VI)/kg). The maximum sorption capacity was obtained with the 1.2 × ECEC ODTMA-modified clinoptilolite (237 mmol Cr(VI)/kg). The organozeolites Na-P1 adsorbed Cr(VI) from aqueous solutions more effectively and were much more durable than the organo-clinoptilolites.

Abstract
Introduction
This study evaluated various remission criteria in abatacept plus methotrexate (MTX)-treated patients with early rheumatoid arthritis (RA). We aimed to investigate the time to, and sustainability of, remission, and to evaluate the relationship between remission, function and structure.

Methods
Post hoc analyses were performed from the 12-month, double-blind period of the Abatacept study to Gauge Remission and joint damage progression in methotrexate (MTX)-naive patients with Early Erosive rheumatoid arthritis (AGREE) in patients with early RA (≤2 years) and poor prognostic factors, comparing abatacept plus MTX (n = 210) versus MTX alone (n = 209).

Results
At month 12, Disease Activity Score 28, Simplified Disease Activity Index (SDAI), Clinical Disease Activity Index and Boolean remission rates were, for abatacept plus MTX versus MTX alone: 47.6 % versus 27.3 %, 33.3 % versus 12.4 %, 34.3 % versus 16.3 %, and 23.8 % versus 5.7 %, respectively. Cumulative probability demonstrated higher proportions achieving first remission and first sustained remission for abatacept plus MTX versus MTX alone (e.g., 23.3 % [95 % confidence interval (CI): 17.6, 29.1] vs 12.9 % [8.4, 17.5] for first SDAI remission over 0–6 months). For patients in SDAI remission at month 3, mean Health Assessment Questionnaire-Disability Index at month 12 was 0.20 versus 0.50 for abatacept plus MTX versus MTX alone. Mean changes in radiographic score from baseline to month 12 were minimal for patients in SDAI remission at month 3 in both groups, while less structural damage progression was seen, 0.75 versus 1.35, respectively, for abatacept plus MTX versus MTX alone for patients with moderate/high disease activity at month 3 (adjusted mean treatment difference: −0.60 [95 % CI: −1.11, −0.09; P < 0.05]).

Conclusions
High proportions of abatacept plus MTX-treated patients achieved stringent remission criteria. Remission was associated with long-term functional benefit; dissociation was seen between clinical and structural outcomes for abatacept. These findings highlight the impact of reaching stringent remission targets early, on physical function and structural damage, in MTX-naïve biologic-treated patients.

Authors: Wade Jennifer , Cooper Mandelin , Ragan Robert 
Published: June 2015

Purpose To evaluate the physical compatibility of vancomycin with piperacillin-tazobactam during simulated Y-site administration. Methods Vancomycin and piperacillin-tazobactam were tested using 2 different diluents: 0.9% sodium chloride and 5% dextrose for injection. Vancomycin concentrations of 2, 5, and 10 mg/mL were tested using 0.9% sodium chloride and 4 and 8 mg/mL in 5% dextrose. Piperacillin-tazobactam was diluted to 16, 30, 40, 80, and 100 mg/mL, representing common concentrations used clinically in hospitals, and concentrations were tested in both 0.9% sodium chloride and 5% dextrose for injection. Medications were reconstituted under USP <797> aseptic technique. Combinations were tested in duplicate and reverse order with control solutions. Compatibility testing for Y-site included visual inspection, inspection with a high-intensity monodirectional light source (Tyndall beam), turbidimeter for turbidity evaluation, pH, and microscopic viewing. Testing occurred immediately after mixing, 15 minutes, 60 minutes, and 4 hours. If inconsistencies were observed between samples, testing was repeated to confirm results. Solutions were deemed incompatible if any one test failed and compatible if all tests were accepted. Results When dextrose 5% for injection was used as the diluent, vancomycin 4 mg/mL was Y-site compatible with piperacillin-tazobactam 16, 30, and 40 mg/mL and incompatible with 80 and 100 mg/mL. Vancomycin 8 mg/mL was incompatible with all tested concentrations of piperacillin-tazobactam. When 0.9% sodium chloride was used as the diluents, Y-site compatibility was found with vancomycin 2 and 5 mg/mL and all tested concentrations of piperacillin-tazobactam. Vancomycin 10 mg/mL was incompatible with piperacillin-tazobactam 40, 80, and 100 mg/mL. Incompatibilities formed a white precipitate immediately on mixing. Conclusion Y-site incompatibility was greater for the tested concentrations of piperacillin-tazobactam and vancomycin when 5% dextrose was used as the diluent versus 0.9% sodium chloride. Y-site incompatibility was seen immediately in the form of a white precipitate on mixing.
Left Atrial Myxoma Causing Coronary Steal: An Atypical Cause of Angina
Authors: Stiver Kevin , Bittenbender Peter , Whitson Bryan A. , Bush Charles A. 
Published: June 2015

Cardiac myxomas are rare primary cardiac tumors that usually present with dyspnea or manifestations of systemic embolization. Coronary steal is a rare phenomenon of unbalanced blood flow that is seen primarily in patients who have undergone coronary artery bypass grafting and have subclavian artery stenosis.
We report the case of a 72-year-old woman who presented with fatigue, weakness, and exertional chest heaviness and had abnormal results on a cardiac stress test. The results of coronary angiography showed no obstructive coronary artery disease but revealed a large intracardiac left atrial mass that was supplied by 2 anomalous coronary arteries. The patient underwent successful ligation of the anomalous coronary arteries and resection of the mass, which was histologically an atrial myxoma. The patient's symptoms resolved, and results of a repeat cardiac stress test were normal.
To our knowledge, this is the first report of a highly vascularized atrial myxoma that caused coronary steal with objective evidence of ischemia, and with subsequent resolution after resection of the mass and ligation of the anomalous coronary arteries.
Evidence For and Against Dietary Recommendations to Prevent Cardiovascular Disease
Authors: Dildy Theresa 
Published: June 2015

Evidence-based dietary guidelines for the prevention of cardiovascular disease have changed significantly over the past 9 years. Now less emphasis is placed on total dietary fat and cholesterol restriction and more emphasis on restricting saturated fat. The public outcry to stop demonizing saturated fats has been around for some time. We are now hearing more agreement from medical researchers and clinicians alike, as they become aware of evidence that some saturated fatty acids are not harmful and some are actually beneficial.
Another criticism of the dietary guidelines is their failure to look at more meaningful outcomes in research. Instead of using low-density-lipoprotein cholesterol to measure risk, they should use markers for inflammation, obesity, diabetes mellitus, and metabolic syndrome—all well-known risk factors for cardiovascular disease. Perhaps the recommendations that arise from dietary research would be more meaningful if they were presented more simply: in terms of whole foods (like dairy products and fresh meat), rather than nutrients (like saturated fat).
Showrooms as a Window to Science Based Innovation
Authors: Boronowsky Michael , Woronowicz Tanja , Hoffmann Peter , Boboev Sangin 
Published: June 2015

Abstract
Scientific results benefit from more tangible stakeholder communication. Showrooms are a tool to transform abstract scientific concepts into solution-oriented and less complex demonstrators. The basic idea of a showroom implies a smart expo and meeting place to demonstrate the latest technological developments in a comprehensive and interactive manner and to stimulate transfer of scientific results to practice. Presentation of new technologies can be an eye opener of what can already be done today. But it is just more than this as it can put discussion with interested stakeholders to a new level - allowing to think beyond this - paving the ground for innovation. This way a showroom stimulates very substantial discussion about future ideas with real involvement of industry and society. Involving the public via a showroom environment is also helpful for the diffusion of new ideas, leading to potential faster market take-up, when new solutions are put into reality. Furthermore the interaction with the public is a stimulus also for the scientist, raising a much better understanding about current and future needs.
Capability is understood as a measure of the ability of an entity (organization, person, system) to achieve its objectives in relation to its overall mission professional science communication is part of the capability of, e.g., a university. Innovation capability in this sense refers to the ability of a set of regional stakeholders from academia, political authorities, public administrations and industry to innovate in synergy for economic and societal development – showrooms are an important tool to achieve this.

Published: June 2015

AbstractThe following note is a brief discussion of the most recent developments in the language debate in Haiti. Our main objective is to raise awareness of the ongoing tensions between those that advocate for some type of bilingual Haitian society and those who passionately seek to empower Haitian Creole. These reflections were triggered by the availability of the first comprehensive linguistic, social and historical account of Haitian Creole, Spears and Joseph's (2010)
Mapping Data - Quality, Quantity Or Both?
Authors: Suba N.Sz. , Suba Şt. 
Published: June 2015

Abstract
In the history of mankind, society was always heavily relying on the knowledge regarding their surroundings. Maps of already known areas were used in different areas of human activity, regardless if they were military applications or for plain orientation purposes. In the modern days of the 21st century, it is almost unimaginable for any corporate or private user to carry out their usual activity without precise knowledge of their (eventually larger than before) surroundings. One thing that changed in the past few years is that although people always used maps, the making of these were in the hand of certain specialists - the land surveyor engineers. Today, to a certain extent, any user can contribute to the expansion of existing maps (or even create new ones), thus leading to a vast dataset included in these maps. While this will theoretically further expand our knowledge regarding our surroundings, a natural question can come in everybody's mind: does the increasing quantity lead to unassailable quality as well? Can we enhance the reliability of existing maps and contribute to nearly error-free future maps?
Application Of The Distributed Plasticity Concept In Quick Nonlinear Analysis Of Reinforced Concrete Shear Walls
Authors: Trifa F. S. , Cătărig A. 
Published: June 2015

Abstract
The paper presents a simplified calculation method to predict, as accurate as possible, the most important characteristics of the behaviour of the slender reinforced concrete shear walls in the inelastic range: failure mode, strength capacity, flexural and shear deformations, sectional and element ductility. The formulation is based on nonlinear beam element with taking into account the influence of shear, both on strength and stiffness of the wall. The principal parameters incorporated in the calculation model are: the rectangular shape of the cross section, the aspect ratio of the wall, the most accurate constitutive relationships for the compressed concrete and for the reinforcement steel, both in compression and in tension (including the strengthening of the steel after yielding), the variation of the Poisson ratio of the concrete, the amount and distribution of the vertical reinforcement. The model uses the concept of distributed (smeared) plasticity along the element and so the flexural deformations are computed by integrating the actual curvatures on the height of the wall. The shear deformations are also calculated, in agreement with the results of some recent experimental researches. The calculation method was then applied to two experimental wall specimens and their force – horizontal top displacement curves were plotted.
Determination of Radiative Heat Transfer Coefficient at High Temperatures Using a Combined Experimental-Computational Technique
Authors: Kočí Václav , Kočí Jan , Korecký Tomáš , Maděra Jiří , Černý Robert Č 
Published: June 2015

Abstract
The radiative heat transfer coefficient at high temperatures is determined using a combination of experimental measurement and computational modeling. In the experimental part, cement mortar specimen is heated in a laboratory furnace to 600°C and the temperature field inside is recorded using built-in K-type thermocouples connected to a data logger. The measured temperatures are then used as input parameters in the three dimensional computational modeling whose objective is to find the best correlation between the measured and calculated data via four free parameters, namely the thermal conductivity of the specimen, effective thermal conductivity of thermal insulation, and heat transfer coefficients at normal and high temperatures. The optimization procedure which is performed using the genetic algorithms provides the value of the high-temperature radiative heat transfer coefficient of 3.64 W/(m2K).

Mobile Wallets’ Business Models: Refining Strategic Partnerships
Authors: Buchinger Uschi , Ranaivoson Heritiana R. , Ballon Pieter 
Published: June 2015

Abstract
Background and Purpose: Though Mobile Wallets have the potential to entirely substitute their physical predecessor, many Mobile Wallets narrow their operations to one particular feature. This might be because of strategic business- model design choices to position themselves strategically as intermediates between users and business partners (third parties) in more delimited markets. Thus, Mobile Wallet Applications (MWAs) often represent platforms in narrow two-sided market structures.
Design/Methodology/Approach: The paper focuses on the economics of such platforms by the means of a business model analysis. It examines how business partners are integrated in four MWAs’ strategies: Key Ring, FidMe, Apple Passbook and Qustomer.
Results: The paper shows that MWAs strive to incorporate not only a large quantity of partners but also such with a high brand value (quality of partners) in their organization design. These partners shape their service design since none of the platforms offer products or services themselves. Hence, MWAs are dependent on the third parties’ capacity and willingness to fulfill engagements and meet the customer demands.
Conclusion: MWAs - though concerned with the inclusion and management of loyalty points and schemes - do not leverage the possibility to generate revenue via third parties’ loyalty points. Theoretically, MWAs could reward or redeem loyalty points themselves.
Sensibilisierung von Kettenvernetzungen in Polystyrol durch aromatische Additive bei Einwirkung ionisierender Strahlung
Authors: Heusinger H. 
Published: June 2015

Zusammenfassung
Bei Bestrahlung von Polystyrol unter striktem Ausschluß von Sauerstoff wird durch Zugabe von Pyren die Zahl der Kettenvernetzungen gesteigert. Dieser Effekt erreicht ein Maximum bei 10-4 Mol Pyren/g Polystyrol. Die Untersuchungen zeigten, daß es sich hierbei nicht um einen Weichmachereffekt handelt. Auch ein Einbau von Additivmolekülen als Brückenglieder in das Polymere kann für diese Beobachtung nicht verantwortlich sein, da das Additiv unverändert aus der Reaktion hervorgeht. Es wird angenommen, daß unterhalb der Einfriertemperatur des Polystyrols (+80 °C) Kettenvernetzungen nicht durch Radikalrekombination erfolgen, sondern die Reaktionspartner angeregte Zustände sind. Die zusätzliche Induzierung von Kettenvernetzungen wäre damit als durch das Additiv sensibilisierte Reaktion zu verstehen.
Mechanical and Optical Properties Characterization of C-Plane (0001) and M-Plane (10−10) GaN by Nanoindentation and Luminescence
Authors: Yokogawa Toshiya , Fujikane Masaki , Nagao Shijo , Nowak Roman 
Published: June 2015

ABSTRACTYield shear stress dependence on dislocation density and crystal orientation was studied in bulk GaN crystals by nanoindentation examination. The yield shear stress decreased with increasing dislocation density which is estimated by dark spot density in cathodoluminescence, and it decreased with decreasing nanoindentation strain-rate. It reached and coincided at 11.5 GPa for both quasi-static deformed c-plane (0001) and m-plane (10-10) GaN. Taking into account theoretical Peierls–Nabarro stress and yield stress for each slip system, these phenomena were concluded to be an evidence of heterogeneous mechanism associated plastic deformation in GaN crystal. Transmission electron microscopy and molecular dynamics simulation also supported the mechanism with obtained r-plane (-1012) slip line right after plastic deformation, so called pop-in event. The agreement of the experimentally obtained atomic shuffle energy with the calculated twin boundary energy suggested that the nucleation of the local metastable twin boundary along the r-plane concentrated the indentation stress, leading to an r-plane slip. This nanoindentation examination is useful for the characterization of crystalline quality because the wafer mapping of the yield shear stress coincided the photoluminescence mapping which shows increase of emission efficiency due to reduction of non-radiative recombination process by dislocation.
