Authors: Mahmood Asif , Ahmad Mahmood , Sarfraz Rai Muhammad , Usman Minhas Muhammad 
Published: May 2016

AbstractIn this work, successful efforts have been performed for solubility enhancement of acyclovir. pH‐sensitive β‐Cyclodextrin‐g‐poly methacrylic acid (MAA) hydrogel microparticles were developed. β‐Cyclodextrin, MAA, N,N‐methylene bisacrylamide were used as polymer, monomer, and cross‐linker, respectively. Nine different formulations (BM‐1 to BM‐9) were prepared by aqueous free radical polymerization. Developed microparticles were characterized for FTIR, Differential Scanning Calorimetry/Thermo Gravimetric Analysis, PXRD, energy‐dispersive x‐ray spectroscopy, SEM, TEM, optical microscopy, zeta sizer, percent equilibrium swelling (%ES), solubility studies, and in vitro drug release studies. Higher swelling results (83.68%) were obtained at pH 7.4 in less than 3 h. Porous surfaces with drug were seen in TEM images. Maximum release was observed at pH 7.4 (89.51%). Solubility enhancement was 7.38‐fold in water as compared to pure acyclovir. Thermal stability of grafted microparticles was increased up to 440.13°C. A potential approach for solubility enhancement was successfully developed.

AimThe objective of this study was to investigate the incidence and characteristics of thoracic injuries associated with cardiopulmonary resuscitation (CPR) performed under the 2005 and the 2010 guidelines.MethodsWe evaluated patients who had an out‐of‐hospital cardiac arrest in 2010 (2005 group) and 2012 (2010 group). We analyzed the incidence and characteristics of rib fractures and pneumothoraces received during CPR as determined by medical records and image studies.ResultsTwo hundred and ninety‐two patients in the 2005 group and 243 in the 2010 group were enrolled. The number of patients with rib fractures was greater in the 2010 group than in the 2005 group (123 [42.1%] versus 167 [68.7%], P < 0.001), and the number of pneumothorax patients with rib fractures was also higher (8 [2.7%] versus 21 [8.6%], P = 0.004). Of the 21 patients, four had a tension pneumothorax. The anterior–posterior diameter of the chest (APD) was smaller in patients with a pneumothorax and rib fractures than those without the injuries (166.0 mm [standard deviation 22.8] versus 176.2 mm [standard deviation 21.0], P = 0.04), and the APD for patients of Japanese descent was smaller than that of patients of European descent by more than 50 mm.ConclusionThe number of rib fractures and pneumothoraces received during CPR increased significantly under the 2010 guidelines when compared with the 2005 guidelines. As the APD for patients of Japanese descent is smaller than that of patients of European descent, Japanese medical facilities need to be prepared for possible fatal adverse events associated with CPR under the current international guidelines.
Reversible selectivity of water/organic solvent mixtures in poly(lactic acid) film

Published: May 2016

ABSTRACTThe separation properties of water/organic solvent mixtures in poly(lactic acid) (PLA) films were investigated. The organic solvent flux increased linearly as the feed concentration increased, whereas the water flux was almost constant up to a feed concentration of 30 wt %. Interestingly, the permselectivity of PLA films was reversed from organic solvent selectivity to high water selectivity depending on the type of organic solvent. The permselectivity was strongly correlated with the solution concentration at which the solvent‐induced crystallization of the PLA films occurred. The selectivity of permeation, solution, and diffusion in water/organic solvent mixtures was determined by the expanded free volume of the PLA films as a result of the interaction between PLA and the water/organic solvent mixture. The permeability behavior of water/organic solvent mixtures in PLA films was very complex. However, it was found that this behavior could be predicted through immersion tests. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 43822.

Published: May 2016

AbstractVertical polyaniline (PANI) nanowire arrays on graphene‐sheet‐coated polyester cloth (RGO/PETC) were fabricated by the in situ chemical polymerization of aniline. The 3D conductive network that was formed by the graphene sheets greatly enhanced the conductivity of PANI/RGO/PETC and improved its mechanical stability. PANI nanowire arrays increased the active surface area of PANI, whilst the hierarchically porous structure of the PANI/RGO/PETC electrode facilitated the diffusion of the electrolyte ions. Electrochemical measurements showed that the composite electrode exhibited a maximum specific capacitance of 1293 F g−1 at a current density of 1 A g−1. Capacitance retention was greater than 95 %, even after 3000 cycles, which indicated that the electrode material has excellent cycling stability. Moreover, the electrode structure endowed the PANI/RGO/PETC electrode with a stable electrochemical performance under mechanical bending and stretching.

AbstractNachdem im Jahr 2009 eine neue moderne Schrägseilbrücke über den Rhein für den Verkehr freigegeben wurde, waren die alte Brücke und deren Pfeiler im Rhein zurückzubauen. Für den Rückbau der Pfeiler war unter den schwierigen Bedingungen im Gewässerbereich eine Spundwandbaugrube zu errichten. Zum Schutz derselben war zusätzlich ein sehr großes Leitwerk als Schutz der Baugrube vor den großen auf dem Rhein fahrenden Schiffen herzurichten. Im Schutze der Baugrube wurde der alte massive Pfeiler konventionell abgebrochen. Nach dem Abbruch des Pfeilers bis weit unter die Gewässersohle waren das Leitwerk und die Baugrube wieder zurückzubauen. Die Arbeiten im Gewässerbereich und deren besondere Aufgabenstellungen werden hier beschrieben.Demolition of the pillar at the right bank of the bridge over the river Rhine by WeselAfter a new modern cable‐stayed bridge across the Rhine was opened to traffic in 2009, the old bridge and its pillars has to be dismantled in the river Rhine. For the dismantling of the pillar a sheet piling pit was erected under the difficult conditions in the water sector. To protect it additionally a very large staging was built to protect the pit from damages with the large Rhine vessels travelling on the river Rhine. Under cover of the pit of the ancient massive pillars were dismantled conventionally. After dismantling the pillar deep below the riverbed, the staging and the pit were dismantled again. The work in the water sector and their special tasks are described.
Querkrafttragfähigkeit von Platten nahe Auflagern

AbstractIn Anbetracht steigender Verkehrslasten und geringer angesetzter Tragfähigkeiten in den vor Kurzem eingeführten Eurocodes steht in den Niederlanden die Querkrafttragfähigkeit vieler bestehender Brücken mit Stahlbetonmassivdecke zur Debatte. In den Normvorschriften werden jedoch günstige Wirkungsmechanismen, wie die Querkraftverteilung in den Platten, nicht berücksichtigt. Man benötigte Forschungsergebnisse, um das Verhalten von Stahlbetonplatten unter Einzellasten in der Nähe von Auflagern zu verstehen. Für diese Studie wurden Versuche an Platten und Balken durchgeführt. Sie zeigten, dass Platten unter konzentrierter Querkraftbelastung eine größere Tragfähigkeit haben als Balken. Das bedeutet, dass für Plattenbrücken ein höherer Belastungswert angesetzt werden kann, sodass weniger Brücken als bisher vermutet einer weiteren Prüfung bedürfen.Shear capacity of slabs close to supports – Overview of experimentsThe shear capacity of many of the existing reinforced concrete solid slab bridges in The Netherlands is subject to discussion due to the higher traffic loads and lower prescribed shear capacities in the recently implemented Eurocodes. However, the code provisions do not take into account beneficial mechanisms such as transverse load redistribution in slabs. Research was needed to understand the behavior of reinforced concrete slabs under concentrated loads close to supports. For this study, experiments on slabs and beams were carried out. The experiments showed that slabs under concentrated loads in shear have a larger capacity than beams. This implies that a higher capacity can be contributed to slab bridges upon assessment, so that less bridges will be identified as needing further study.
Einfluss der Faserzugabe auf die Streuung im Zugtragverhalten von Stahlfaserbeton
Authors: Hadl Philipp , Tue Nguyen Viet 
Published: May 2016

AbstractStahlfaserbeton wird seit Jahrzehnten in verschiedenen Bereichen des Bauwesens erfolgreich eingesetzt. Hauptsächlich kommt Stahlfaserbeton aber in Form von Industriefußböden zur Anwendung. Die großen Streuungen in den Materialkennwerten erschweren die Anwendung für Bauteile mit nennenswerten Beanspruchungen. Daher wurden umfangreiche experimentelle Untersuchungen zur Streuung des Zugtragverhaltens von Faserbeton durchgeführt. Diese beinhalten 4‐Punkt‐Biegezugversuche an großformatigen Balken sowie an Standardbiegebalken nach DAfStb‐Richtlinie Stahlfaserbeton. Die Balken unterscheiden sich in verwendetem Fasergehalt und ‐länge sowie nach der Art der Faserzugabe. Nach Durchführung der Biegezugversuche wurde entlang der Balken die Faserorientierung und ‐verteilung mit dem fotooptischen Verfahren bestimmt. Die Ergebnisse zeigen, dass die Faserverteilung stark streut, während die Faserorientierung nur in geringem Maße schwankt. Sowohl in den Biegezugversuchen als auch in der Auswertung der Schnittbilder ist der Einfluss der Faserzugabeart feststellbar. Die Streuung im Tragverhalten kann durch eine geeignete Faserzugabe und folglich homogenere Faserverteilung reduziert werden.Influence of fibre addition on the scattering in the post cracking tensile behaviour of steel fibre reinforced concreteSteel fibre reinforced concrete (SFRC) has been successfully used in certain areas of concrete constructions. However, the main area of application remains industrial concrete floor slabs. The large scattering in the material properties impedes the application for components with significant loads. Therefore, extensive experimental investigations on the scattering in the tensile post cracking behaviour of SFRC were carried out. The investigations include 4‐point‐bending tests on large‐sized beams as well as standardized beams according to the German guideline for fibre concrete. The specimens differ in fibre amount, fibre length and type of fibre addition. After bending tests, the fibre orientation and distribution were determined along all specimens by using an opto‐analytical method. The test results demonstrate that the fibre orientation is almost constant, while the fibre distribution scatters significantly. In bending tests as well as the opto‐analytical analysis, the influence of the type of fibre addition is evident. Consequently, the scattering in the mechanical behaviour can be reduced by a suitable fibre addition and thus a more homogeneous fibre distribution can be gained.
Real‐time Simulation of Catheterization in Endovascular Surgeries

Published: May 2016

AbstractThis paper proposes an efficient and stable numerical method for modeling catheterization during endovascular surgeries. The guidewire‐catheter combination is treated as an elastic rod, which has very large resistance against twisting about its medial axis. A torsion free assumption is made, and the physical behavior of the rod is predominately governed by stretching and bending energies. This simplification greatly reduces the computational complexity and makes the model more stable, while the simulation results are still realistic enough for its application in endovascular surgeries. A contact handling algorithm that directly makes use of the volume data of the relevant tissues is proposed to simulate the interaction between the guidewire‐catheter combination and the aortic wall. During each simulation step, the penetration depth of each vertex in contact with the aortic wall is calculated using moving least squares surfaces, and the contact is then resolved in a position‐based manner. A comprehensive quantitative evaluation of the rod model is performed to validate its accuracy. Finally, the proposed approach is applied in a prototype system for simulation of endovascular aneurysm repair surgeries. Its efficiency and effectiveness are demonstrated in a real‐time interactive catheterization simulation. Copyright © 2016 John Wiley & Sons, Ltd.

Published: May 2016

AbstractChemical air scrubbers reduce the concentration of water‐soluble components such as ammonia from the outgoing ventilation air through absorption in water, followed by chemical conversions and removal of the end products. A mechanistic model for a countercurrent air scrubber was set up. Mass balances for ammonia, hydrogen sulfide, nitrous oxide, and methane were implemented, as well as the water mass balance and heat balances. The model was validated against experimental data from a conventional fattening pig housing facility. The effect of influent characteristics, design parameters, and control handles on the removal efficiency, the temperature profile, and the water evaporation rate were investigated through simulation. The model was able to describe the behavior of a countercurrent chemical air scrubber.
A New Stripping Column Process and Optimization of Its Operation
Authors: Li Guoqing , Gao Dan , Shi Junjun 
Published: May 2016

AbstractRegarding a kind of stripping column that is widely used in the chemical industry and which operates in total cold reflux and without top light product, a new stripping process is suggested. It takes dual feeds of the hot plus the cold feed, by replacing part of the cold reflux with a part of cold feed, resulting in significant reduction of energy consumption and simplification of the overhead vapor route. As no changes on the column body and only a pipe are needed, this new process can be implemented conveniently in retrofitted projects. Further, an optimization study is developed for choosing the proper flow rate of the cold feed and the appropriate column running pressure. An application in a stripper dealing with the pre‐hydrotreating reaction products of an oil catalytic reformer shows that the new process is valid.
Interactive Thermal Effects on Metal–Organic Framework Polymer Composite Membranes
Authors: Cacho‐Bailo Fernando , Téllez Carlos , Coronas Joaquín 
Published: May 2016

AbstractPolymeric membranes are important tools for intensifying separation processes in chemical industries, concerning strategic tasks such as CO2 sequestration, H2 production, and water supply and disposal. Mixed‐matrix and supported membranes have been widely developed; recently many of them have been based on metal–organic frameworks (MOFs). However, most of the impacts MOFs have within the polymer matrix have yet to be determined. The effects related to thermal behavior arising from the combination of MOF ZIF‐8 and polysulfone have now been quantified. The catalyzed oxidation of the polymer is strongly affected by the MOF crystal size and distribution inside the membrane. A 16 wt % 140 nm‐sized ZIF‐8 loading causes a 40 % decrease in the observed activation energy of the polysulfone oxidation that takes place at a temperature (545 °C) 80 °C lower than in the raw polymer (625 °C).
