Effects of alkali sulfates in clinker on hydration and hardening performance of Portland cement
Authors: Sun Huaqiang , Qian Jueshi , Xiong Qingqing , Yang Sha , Niu Maowei , Deng Lingxi , Huang Yongbo
Published: September 2017

In this study, two main alkali sulfates – aphthitalite and calcium langbeinite – fabricated in a laboratory are added to an industrial clinker with low alkali and sulfate content in order to adjust the contents of alkali sulfates in the clinker. Based on measuring the dissolution rate of the alkali sulfates and ion concentration in tricalcium aluminate (C3A)–alkali sulfate–water (H2O) systems compared with gypsum, and testing the heat flow, compressive strength, setting time and linear deformation of cement with different alkali sulfate contents, the differences between the alkali sulfates and gypsum are analysed. It is shown that aphthitalite could not act as a retarder, whereas calcium langbeinite can act to achieve almost the same retardation as gypsum. In view of the volume stability and strength development of cement, aphthitalite has a negative action when the equivalent sodium (Na2Oe) content induced is above 1·42%. The X-ray diffraction analysis patterns and scanning electron microscopy images show that aphthitalite restrains ettringite formation. It is suggested that more attention should be paid to the negative action of aphthitalite when alkali and sulfate contents in clinker appear to be high.
Physical retardation mechanism of latex polymer on the early hydration of cement
Authors: Han Dongdong , Chen Weideng , Zhong Shiyun
Published: September 2017

The physical retardation effects of styrene/butyl acrylate copolymer latex on the early hydration of cement were investigated, with emphasis of the deformation of polymer particles adsorbed on cement. Five latexes with different glass transition temperatures were prepared by changing the soft monomer (butyl acrylate) content. The diameter of the polymer particles in colloidal solution was studied by dynamic light scattering and the diameter of the polymer particles adsorbed on cement was observed by environmental scanning electron microscopy. It was found that the diameters of polymer particles adsorbed on cement were larger than those in colloidal solution, especially for polymer particles with a high content of soft monomer. The ‘real coverage area’ of polymer particles on cement was theoretically calculated according to the number average diameter of polymer particles adsorbed on cement. It was found that, instead of the adsorption amount of polymer on cement, the real coverage area of polymer on cement is positively correlated with the setting time of latex-modified cement paste. A higher content of soft monomer led to easier deformation of the polymer particles adsorbed on cement, so that the retardation effect of latex on the early hydration of cement increased.

Published: September 2017

Coal combustion residues are produced in large volumes and have been dumped as waste products over many years. The use of bottom ash (BA) as a partial replacement for Portland cement (PC) is an economical use of this thermal power plant by-product. The study reported here aimed to characterise BA of different sizes for use as 10–40% PC replacement. Chemical and physical characteristics such as chemical composition, phase analysis, microstructure, density and compressive strength were examined. With 10% 63 μm BA, the density slightly decreased while the strength was almost identical to that of the control PC mix. Scanning electron microscopy images revealed the flat and hexagonal shapes of calcium silicate hydrate gel. Calcium carbonate enhanced the hydration process of C3S while the ternary phase diagram of calcium oxide–silicon dioxide–aluminium oxide showed that a mix with 10% BA was in the high-calcium zone.
Sustainable road bases with microbial precipitation
Authors: Porter Hannah , Dhami Navdeep Kaur , Mukherjee Abhijit
Published: September 2017

The Australian road network is nearly a million kilometres long, of which 83% can be classified as rural roads. The size and remote nature of Australia's road network pose unique challenges in terms of asset monitoring and maintenance costs. Cement stabilisation is a practice commonly used to improve durability and reduce inspection and repair costs. However, due to the sheer length of the road network, a huge quantity of cement is consumed in stabilisation work, making this practice unsustainable. This paper explores a sustainable alternative through augmentation of the traditional cement-based stabilisation with microbial carbonate precipitation. The calcium carbonate crystals formed within the samples were investigated by scanning electron microscopy and X-ray diffraction. Bulk mechanical properties were characterised through unconfined compressive strength (UCS) testing and the digital image correlation technique was utilised during UCS testing to extract more refined information such as local deformation and strain build-up. The mechanical properties at the microscopic scale were characterised through nanoindentation testing. The results show that microbial precipitation is able to increase the strength of cement-stabilised and road base materials significantly and can considerably improve the technological, economic and social sustainability of Australian road bases.

Influence of chest physiotherapy on mulitple breath washout in children with cystic fibrosis v1
Authors: Voldby Christian , Green Kent , Rosthøj Susanne , Kongstad Thomas , Philipsen Lue , Buchvald Frederik , Skov Marianne , Pressler Tania , Gustafsson Per , G. Nielsen Kim
Published: September 2017

It is presumed that early detection and treatment of the chronic lung diseases cystic fibrosis (CF) and primary ciliary dyskinesia (PCD) are crucial for improving the prognosis. Mucus stagnation and secondary infections and inflammation in the airways causes progressive lung damage from infancy in CF and PCD, which again causes early death in CF and reduced pulmonary function in PCD. Early detection of ongoing lung damage will facilitate early intervention with intensive treatment, enhance disease surveillance and further improve preventive treatment. This will improve quality of life for patients with both CF and PCD and likely improve survival in CF. Pulmonary function is an important marker of prognosis and effect of treatment, but current pulmonary function tests do not register the earliest damages in the lungs in school children – and are inappliccable for infants and toddlers due to requirements for good coorporation. For this reason there is a demand for more sensitive methods that can be used in all age groups. Gas washout – multiple breath inert gas washout (MBW) – is a method that meets these criteria and seems promising for detection of minimal lung damage prior to debut of clinical symptoms and detection by other methods. MBW is for the first time in Denmark established in the Pediatric Pulmonary Service at Copenhagen University Hospital, where a recently established ”Respiratory Physiology Lab for Children” offers a wide range of methods to detect lung disease in children. Aim: The aim of the Ph.D.-project is to investigate: Reliability of results conducted from MBW measurements under different standardized conditions (reproducibility), including establishment of a Danish reference material for children. Whether MBW can be used as a marker of early lung disease compared to conventional lung function methods in the chronic lung diseases CF and PCD. Whether MBW can be used as a relevant outcome to detect interventions in basic CF treatment. The Ph.D.-project will generate a new and more aggressive approach to surveillance and treatment of patients with CF and PCD with an overall aim to reduce morbidity and mortality and improve quality of life. Furthermore, it is expected that this project will generate new knowledge that can be used in the more common lung diseases asthma and COPD, which affects 10% and 15% of children and adults, respectively.

Published: September 2017

The paper focuses on the development of the questionnaire Scales of Academic Motivation in School-Age Children based on the Academic motivation questionnaire for university students previously developed by T.Gordeeva, O.Sychev and E.Osin.The theoretical foundation of this questionnaire is the self-determination theory and its subtheory of intrinsic and extrinsic motivation.Confirmatory factor analysis proved the 8-scale structure of the questionnaire defining three closely related types of intrinsic motivation (learning, achievement and self-development motivation), four typical types of extrinsic motivation in learning activity (self-respect motivation, introjected motivation, two types of external motivation), and amotivation.All scales demonstrate acceptable reliability (0,72 < α < 0,90) and expected correlations with indicators of persistence in learning, subjective well-being and academic achievement.Basing on the revealed gender differences in motivation the paper presents normative data both for adolescent girls and boys. This research was carried out with the support of state subsidies allocated to the National Research University Higher School of Economics within the programme of state support of Russia’s leading universities in order to enhance their competitiveness among major global scientific and educational centers.
A simulated metagenomic analysis of the gut microbiota of Anorexia Nervosa patients using PICRUSt
Authors: Kanji Farhaan , Khurana Himanshi , Sherry Caitlin , Ng Evangeline
Published: September 2017

Introduction

Mack et al. (2016) studied the fecal bacteria and archaea of 55 European normal-weight participants (NW), 55 European patients with anorexia nervosa (ANT1), and 44 ANT1 patients following a body mass index increase (ANT2). Spreadsheets of identified microbes and their relative abundance per patient were uploaded to the EBI Metagenomics web server by Mack et al. We aimed to further study the functions of the identified microbes using the PICUSt algorithm (Langille, 2013) and see if these functions are consistent with published literature.

Methods

Spreadsheets were downloaded from EBI Metagenomics (Project# ERP012549) in JSON Biom format and uploaded to a Galaxy cloud server hosting PICRUSt. All data transformations can be viewed at http://huttenhower.sph.harvard.edu/galaxy/u/farhaansgroup/h/anorexi-astem-2017 . Transformed datasets were downloaded, appended with a .biom file extension, converted to the SPF format using STAMP v2.1.3 (Parks, 2014), and merged into a single file using Microsoft Excel for analysis with STAMP. Differences in propionate metabolism between ANT1, ANT2, and NW samples was chosen for further study.

Results & Discussion

The proportion of propionate metabolism genes was not significantly different between ANT1 and NW samples (p=0.08), but was different between ANT2 and NW samples (p=0.01) using a pair-wise Welsh’s t-test (0.95 CI) with a Storey FDR multiple test correction. In comparison, Mack et al, detected no differences in propionate concentration between AN and NW fecal samples using gas chromatography while Morito et al (2015) found lower concentrations of propionate in Japanese AN versus NW fecal samples using liquid chromatography. Our discrepancy with Mack et al could have arisen since PICRUSt cannot analyze the genes of eukaryotes, PICRUSt is limited by the depth and breadth of the gene annotations in the KEGG database, and our experimental setup cannot provide data on gene expression. Moreover, 18% of V4 16S rRNA DNA sequences could not be matched to any bacteria or archaea by EBI Metagenomics. In conclusion, while in silico experiments can be useful to predict microbial functions in a sample, in this case, our PICRUSt-based hypothesis that fecal samples from Mack et al would have different concentrations of propionate between AN and NW samples was not borne out by Mack et al’s chromatography experiments. Nonetheless, the conflicting findings between us, Mack et al, and Morito et al warrants further research on whether microbes mediate carbohydrate metabolism differently in patients with a history of anorexia nervosa versus controls.

We propose an algorithm for correcting X-ray image distortions caused by central projection. Relationships between coordinates of X-ray image points obtained using parallel and central projection are derived. We describe two correction techniques using which the original image can be made similar to the one based on parallel projection. In this way, the three-dimensional heart vessel model can be essentially simplified and diagnostic parameters can be assessed with higher accuracy, resulting in a more accurate early disease diagnosis.

A model of phase field has been developed to investigate the microstructure evolution during selective laser melting (SLM) of metal powder bed. A two-component (degree of order, orientation field) ordering parameter has been used, for which the permissive relationships have been derived reasoning from the principle of entropy production positivity. The application of this principle has made possible obtaining the thermodynamically agreed evolutionary equations for the components of the ordering parameter, conjugate with the fields of temperature, admixture concentration and elastic deformations for the non-isothermal conditions of crystallization of pure metal melts and multicomponent alloys. The model of the microstructure is adjoint with the macroscopic thermodynamic model of SLM that accounts for the processes of heat transfer, thermo-capillary convection and evolution of the melt free surface.

A comparative numerical calculation of the propagation of a zero-order Bessel laser beam in a uniaxial crystal perpendicular to its axis is performed using the Rayleigh-Sommerfeld integral operator, generalized for an anisotropic environment. Numerical simulation is performed with a different type of beam polarization and different characteristics of the Bessel beam. Patterns of the beam intensity during the passing of different distances in the crystal are obtained, showing the degree of astigmatic transformation, which makes it possible to determine the conditions under which the greatest astigmatic distortion of the beams occurs. The above analysis can be useful in practice for determining the anisotropy characteristics of a crystal.

Published: September 2017

Currently, a wide range of high-performance environments is available for a researcher to perform computations. It is a really difficult task to select an environment in which the computations will be completed as soon as possible. To solve this, you need to analyze the load of the environment computing resources, and also to predict their availability in the future. In this paper we describe a solution for prediction of computing resources load in a cluster environment using neural network models. We considered a process of configuring the neural network architecture: selection of activation functions, algorithms of initialization and updating of the weights of neurons. Training and testing was performed on a set of data for the load of the cluster "Sergey Korolev" for the period from November 2013 to December 2016.

Las nuevas realidades sociales y ambientales en la transformación del derecho
Authors: Valencia Hernández Javier Gonzaga
Published: September 2017

La construcción del conocimiento jurídico ha estado en el péndulo de lo práctico o técnico instrumental y lo teórico conceptual, es entre estos dos extremos en los que han aparecido las diferentes concepciones y modos de ser y de hacer del derecho. El derecho como ciencia, como técnica de control social, como instrumento de solución de conflictos, como conjunto de normas que regulan las relaciones de los seres humanos, ha seguido el camino recorrido por las diferentes disciplinas del saber llámense ciencias naturales, ciencias sociales o ciencias del espíritu, en la constitución de su estatuto científico.
En la tensión de explicar o comprender, describir o prescribir, entre la validez y la eficacia, la legitimidad y la legalidad, se ha desarrollado el conocimiento de lo jurídico en el mundo moderno, desde las teorías iuspositivistas, las iusnaturalistas, las realistas, hasta las propuestas contemporáneas como la teoría crítica del derecho y la autopoiesis del derecho.

Research Capacity Building: A Historically Black College/University-Based Case Study of a Peer-to-Peer Mentor Research Team Model
Authors: Moore Corey L. , Manyibe Edward O. , Aref Fariborz , Washington Andre L.
Published: September 2017

Purpose: To evaluate a peer-to-peer mentor research team model (PPMRTM) in building investigators’ research skills (i.e., research methods and grant writing) at a historically Black college/university (HBCU) in the United States. Method: Three different theories (i.e., planned change, critical mass, and self-efficacy), contemporary study findings, and our personal experiences as HBCU-based investigators provided a useful framework for developing the PPMRTM and corresponding intervention components. Three faculty members (herein referred to as fellows) and 5 mentors participated in the study. A concurrent equal status mixed methods design was used to triangulate data collected from 2 different sources: (a) a mixed methods (i.e., qualitative and quantitative) Web-based survey and (b) telephone interviews. The data were analyzed using SPSS Version 22 and NVivo Version 10.0. Results: The findings indicated that mentors and fellows were satisfied with the mentorship relationship, the program design, and its processes. Fellows submitted, for the first time in their career, a research proposal to the National Institute on Disability, Independent Living, and Rehabilitation Research Minority Serving Institution-Field Initiated Program (Catalog of Federal Domestic Assistance [CFDA 84.133]; G-4 research or G-5 development) for competitive funding consideration. This was a core goal of the program. They also indicated that their confidence to conduct research improved. Conclusions: The results suggest that the PPMRTM could represent a promising conceptual framework for conducing mentorship at HBCUs and other minority-serving institutions to improve early career research scientists’ research skills.
Influence of Silicate and Calcium Ions to Transport of Phosphate Ion through Polymeric Inclusion Membrane (PIM)
Authors: Rumhayati Barlah , Fardiyah Qonitah , Musyarofi Himayatul
Published: September 2017

Measurement of phosphate ions by molybdenum blue method is influenced by the presence of interfering ions, such as silicate and calcium ions. To obtain an accurate measurement, interference ions should be separated from the phosphate ion. Separation could be carried out with extractions using PIM method. The effectiveness of separation based on PIM method depends to the transport efficiency of targeted ion from feed phase to stripping phase. The aim of this research was to determine the effect of silicate and calcium ions to phosphate ion transport through PIM. PIM was prepared by mixing PVC as polymer, 1,10-dekanadiol as a plasticizer, and Aliquat 336-Cl as extractant in the solvent THF. Extraction was performed by using a diffusion cell, The cell was consisted by two containers, i.e  feed phase container and stripping phase container which was separated by PIM. Feed phase was a mixture of phosphate 100 mg / L and SiO32- at 5; 10; 15; 20 and 25 mg/L for studying the effect of silicate ion. Investigation of calcium ion effect was conducted by using a mixture of phosphate solution of 100 mg / L and Ca2+ of 1.13x10-4; 2.26x10-4 and 4.52x10-4 mg/L in the feed phase. The stripping phase was the solution of NaCl 0.1 M. Both containers were stirred for 3 hours at 180 rpm. The solution in the both containers  was taken for 1 mL every 30 minutes. Phosphate ion was measured by visible spectrophotometry at 690 nm with molybdenum blue method. Silicate ion was determined by visible spectrophotometry at a wavelength of 410 nm with molybdenum blue method. Calcium ion was determined by AAS. The results showed that the higher concentration of calcium ions, the lower the phosphate ion transport efficiency. Only 34.46% of phosphate ions transported in the presence of calcium ions up to 4,52x10-4 mg/L. Meanwhile, PIM was more selective to silicate ion than ion phosphate at the silicate ion concentration up to 15 mg/L. At higher concentration of silicate ions, PIM was more selective to phosphate ion.
