Authors: Triyudanto Aryo N. , Lubis Andri M.T. 
Published: January 2017

Background: Despite the advances in the design and fixation of implants in total knee replacement (TKR). the amount of postoperative bleeding is still an important issue that has not been resolved. This study aimed to measure the effectiveness of various tranexamic acid administration.
Methods: This was a randomized controlled trial study, held from August 2014 to February 2016 at Cipto Mangunkusumo Hospital, Jakarta. Twenty two patients having TKR were divided into three groups: the control group, the tranexamic acid intra-articular-intraoperative group, and the intravenous preoperative group. Intraoperative bleeding, haemoglobin (Hb) level on preoperative to five-day-post-surgery, total drain production, total blood tranfusion needed and the drain removal timing were recorded and compared. Numerical data were analyzed by using parametric and non-parametric test, depended on the normality of the data.
Results: The amount of blood transfusion needed in both the intra-articular group (200±SD 100 mL) and the intravenous group (238±SD 53 mL) were significantly different compared to those in the control group (1,016±SD 308.2 mL) (p=0.001). Meanwhile, there was no significant difference between the amount of blood transfusion needed in the intra-articular group and the intravenous group. Total drain production in the intra-articular group (328±SD 193 mL) and intravenous group (391±SD 185 mL) was significantly different compared to the control group (652±SD 150 mL) (p=0.003). No significant difference between the levels of both preoperative and postoperative haemoglobin, the amount of intraoperative bleeding, and the duration of drain usage.
Conclusion: Intravenous and intra-articular tranexamic acid effectively decreased transfusion volume and drain production in patients undergoing TKR.

Optical lens-shift design for increasing spatial resolution of 3D ToF cameras
Authors: Lietz Henrik , Hassan M. Muneeb , Eberhardt Jörg 
Published: January 2017

Abstract
Sensor resolution of 3D time-of-flight (ToF) outdoor-capable cameras is strongly limited because of its large pixel dimensions. Computational imaging permits enhancement of the optical system’s resolving power without changing physical sensor properties. Super-resolution (SR) algorithms superimpose several sub-pixel-shifted low-resolution (LR) images to overcome the system’s limited spatial sampling rate. In this paper, we propose a novel opto-mechanical system to implement sub-pixel shifts by moving an optical lens. This method is more flexible in terms of implementing SR techniques than current sensor-shift approaches. In addition, we describe a SR observation model that has been optimized for the use of LR 3D ToF cameras. A state-of-the-art iteratively reweighted minimization algorithm executes the SR process. It is proven that our method achieves nearly the same resolution increase as if the pixel area would be halved physically. Resolution enhancement is measured objectively for amplitude images of a static object scene.
‘If I didn’t know you what would you want me to see?’: Poetic mappings in neo-materialist research with young asylum seekers and refugees
Authors: Frimberger Katja , White Ross , Ma Lyn 
Published: January 2017

AbstractThe following article puts to work an affirmative approach to critical theory through poetic mappingsofthe process of craftingidentity boxeswith ESOL students from refugee and asylum backgrounds in a Glasgow-based college in Scotland (UK). The article takes as its starting point the work of feminist and neo-materialist thinkers who argue for an ontological re-orientation of our practices of inquiry. This involves the questioning of positivist research orientations, which regard language as mere second-order representations of a primary reality. We argue that such representationalist logic can implicate research participants in deficit orientations, especially when their embodied and often contested ways of being in the world defy purely linguistic or other ‘fixed’ cultural representations. With the aim to embrace epistemological uncertainty and prioritise our participants’ embodied self-articulations over our “rage for meaning” (MacLure 2013), we experimented with poetic mappings as neomaterialist, arts-based research tools.
Beliefs and practices of foreign language learning: A visual analysis
Authors: Chik Alice 
Published: January 2017

Abstract
This paper analyzes visual and multimedia narratives produced by learners of different age groups and linguistic and cultural backgrounds to explore (a) their beliefs and practices of foreign language learning; and (b) visual metaphors used by learners in hand-drawn and computer-mediated texts. The texts were collected from language learners from primary school to university in Sydney, Berlin, and Hong Kong. These learner narratives add new dimensions to our understanding of learners’ beliefs and practices: what learners think learning a particular language involves, what they hold to be true and what they actually do. While using interviews and written texts is an established practice in narrative inquiry research, only a few studies have adopted visual data. The findings point to three implications. First, drawing instructions to learners directly influenced how learners represent their learner beliefs. Second, while self-composed language portraits and photographs encourage reproduction of meanings across modes, stock visuals are more likely to be used to create juxtaposed meanings. Finally, the idea of kawaii was used as a visual metaphor when discussing negative emotions, which may point to a new component in digital and visual expression.

AbstractA mild and sustainable synthesis of 2,2-disubstituted oxetanes has been achieved through the use of a flow microreactor system. By controlling the residence time a highly unstable intermediate such as 2-phenyloxetan-2-yl lithium can be generated and trapped with various electrophiles affording in moderate to good yields 2-substituted-2-phenyloxetanes at higher temperatures with respect to macrobatch-mode where –78 °C is required.
Photocatalytic Hydrogen Evolution by tris-dithiolene tungsten complexes
Authors: Koutsouri Eugenia , Mitsopoulou Christiana A. 
Published: January 2017

AbstractHerein, we report on the homogeneous photocatalytic evolution of hydrogen by using as reductive catalysts the prismatic symmetric tris – dithiolene complexes of the tungsten, namely [W{S2C2(Ph)2}3] (1) and its monoanion [W{S2C2(Ph)2}3](TBA) (2). Complex 2 is fully characterized by elemental analysis, ESI-MS, IR, UV-Vis and fluorescence spectrophotometry as well as cyclic voltammetry. The photocatalytic system consists of [ReBr(CO)3(bpy)] as a photosensitizer, triethanolamine as a sacrificial electron donor and acetic acid as the proton source. Although the activity of the photocatalytic system is rather small (TON=18), it indicates that the homoleptic tris dithiolene complexes can act as proton reductive catalysts with their monoanion form to be more active in accordance with the findings for the bis - dithiolene complexes.
Preparation and characterization of cellulose paper/polypyrrole/bromophenol blue composites for disposable optical sensors
Authors: Gonçalves Débora 
Published: January 2017

AbstractThis manuscript describes a novel approach for the preparation of composites based on cellulose paper (CP) modified with polypyrrole (PPy) and bromophenol blue (BPB) (CP/PPy/BPB). Cellulose fibers are suitable for uniformly retaining the polymer in its doped form, once BPB can be used as a negatively charged dye. The CP/PPy/BPB composites were characterized by Raman Spectroscopy, Scanning Electron Microscopy, Spectroscopy and Dispersive Energy, and X-ray Diffraction. After characterization, they were studied for the quantification of pH and ammonia by diffuse reflectance spectroscopy. Under varying pH, different colors were verified, which ranged from yellow to blue, and an optical response for ammonia at concentrations as high as 25 ppm. The replacement of BPB by bromothymol blue (BTB) did not produce efficient color transitions and showed no sensitivity to changes in pH and ammonia concentration.
A more sustainable membrane preparation using triethyl phosphate as solvent
Authors: Marino Tiziana , Blefari Serenella , Di Nicolò Emanuele , Figoli Alberto 
Published: January 2017

Abstract
In this work, hydrophobic poly(vinylidene fluoride) membranes for potential membrane distillation applications, with pore sizes ranging from ~ 0.05 to ~ 0.30 μm, were prepared by employing triethyl phosphate (TEP) as a substitute to the hazardous, commonly used, toxic solvents. Membrane morphologies and properties were tailored based on the main parameters, such as the casting solution composition and the operational conditions, which affect the phase inversion process. Experimental results showed that exposure time to controlled humid air and temperature, as well as additive content in the dope solution, strongly influence the membrane formation. The use of TEP as an alternative solvent may contribute to the development of sustainable separation operations.
Carbon fibres from precursors produced by dry-jet wet-spinning of kraft lignin blended with kraft pulps
Authors: Olsson Carina , Sjöholm Elisabeth , Reimann Anders 
Published: January 2017

Abstract
A part of kraft lignin (KL) can be used as a value-added product without detracting the chemical recovery and the energy balance of the kraft mill. The focus of this study is the production of light-weight carbon fibres (CFs) from KL obtained by the LignoBoost process. For this purpose, crude KL and various cellulose products from kraft pulping of hardwood (HW) and softwood (SW) were dissolved in 1-ethyl-3-methylimidazolium acetate ([EMIm][OAc]) and submitted to dry-jet wet-spun to obtain precursor fibres containing 70% KL and 30% cellulose, which were thermally stabilised and further converted by thermal treatments into CF. The initial and final products were characterised with respect to, e.g. mole mass distribution, thermal properties, tensile strength and tensile modulus determination. The optimised precursor fibres are smooth and flexible with similar mechanical properties as commercial textile fibres. The best CFs made had a tensile strength of 780 MPa and a tensile modulus of 68 GPa and are thus stronger and stiffer than those produced by melt-spinning of SW-based lignins alone. The new CFs based on dry-jet wet-spun precursors still have a high potential for further improvements.
Effect of High Temperature Hot Corrosion on the Compression Creep Behavior of 12Cr1MoV Alloys
Authors: He Jianjun , Xiong Weizhou 
Published: January 2017

AbstractThis paper highlights the effect of 70 %NaCl–30 %KCl salt mixture on compression creep properties of 12Cr1MoV alloys at 100 MPa (948.15 K, 973.15 K and 998.15 K) in air using bare specimens and specimens in corrosive environment. The corrosive specimens were also tested at 923.15 K (150 MPa, 175 MPa and 200 MPa). Experimental results showed that the specimen in chloride mixture showed relatively high compression creep strain and steady-state creep rates compared with the bare specimen, and this effect accelerated with the increased temperature, especially when it was above 973.15 K. The creep mechanisms of the specimen in chloride mixture were inferred from gliding and climbing of dislocations of the stress exponent. Damage of hot corrosion in creep deformation was found to be associated with the layer fracture attributing to the initiation and propagation from the intergranular cracks and reduction of the bare area caused by the internal transgranular attack of chloride mixture.

Published: January 2017

Abstract

Background:
Butter is one of the widely used fats present in the diet. However, there is no satisfactory study available that evaluates the effect of a high-fat diet containing butter as the principal fat on the development of non-alcoholic fatty liver disease (NAFLD).

Methods:
In the present study, butter was used for the development of steatosis in Chang liver cells in an in vitro study and Swiss albino mice in an in vivo study. In vitro steatosis was established, and butter was compared with oleic acid in Chang liver cells using an oil red O (ORO)-based colorimetric assay. In the in vivo study, a butter-rich special diet was fed for 15 weeks to mice, who showed no significant change in body weight. The expression pattern of phosphatase and tensin homolog (PTEN) and miR-21 was compared by reverse transcriptase-PCR.

Results and Conclusions:
Special diet-fed animals showed downregulated PTEN compared to normal diet-fed animals, while levels of miR-21 remained the same. Elevations in biochemical parameters, viz., triglycerides and liver function tests showed symptoms of onset of NAFLD. Histophathological study of livers of test animals confirmed mild-to-moderate degree of NAFLD.
Conjectures on additively divisible commutative semirings
Authors: Kepka Tomáš , Korbelář Miroslav 
Published: January 2017

AbstractWe present a series of open questions about finitely generated commutative semirings with divisible additive semigroup. In this context we show that a finitely generated additively divisible commutative semiring is idempotent, provided that it is torsion. In the particular case of a one-generated additively divisible semiring without unit, such a semiring must contain an ideal of idempotent elements.

Abstract
A new PEG-containing liquid crystalline side chain block copolymer HBC-PEG550 was prepared from poly(ethylene glycol)-b-poly(2-(diethylamino) ethyl methacrylate copolymer (BC-PEG550) and 8-(4-cyanobiphenyl-4′-oxy) octan-1-ol (LC8) by molecular self-assembly processes via hydrogen bond formation between amine group of HBC-PEG550 and hydroxyl group of the LC8. The formation of H bond was confirmed by using FTIR spectroscopy. The liquid crystalline behavior of the HBC-PEG550 was investigated by differential scanning calorimeter (DSC) and polarized optical microscopy. Dielectric properties of HBC-PEG550 and HBC-PEG550 has been studied by impedance spectroscopy. Real and imaginary parts of complex dielectric constant, impedance, and energy loss tangent factor for HBC-PEG550 and HBC-PEG550 have been characterized in the frequency range of 100 Hz–15 MHz.
Estimation of the phosphorus loading with consideration for the planetary boundaries (for the Russian Federation as an example)
Authors: Tarasova Natalia P. , Makarova Anna S. , Vasileva Evgeniya G. , Savelova Diana D. 
Published: January 2017

AbstractSome scientists believe today that problems related to phosphorus entry into fresh-water bodies may be more important for setting the planetary boundary. Excessive entry of biogenic elements (especially phosphorus) into water bodies and water streams causes their eutrophication. This process may cause a decrease in the light transmittance of surface water layers and other consequences for ecosystem and humans. In this paper the results of model application for the estimation of the phosphorus content in fresh waters of the Russian Federation regions are presented. The method for the estimation of the phosphorus amount in fresh water was developed on the basis of the dynamic model. Phosphorus loading is most characteristic of regions that have developed types of agriculture which cause increases the rate of mineral phosphorus entry into erodible soil.
