Authors: Yanti Gusneli , Zainuri Zainuri , Megasari Shanti Wahyuni
Published: November 2018

Perkembangan konstruksi bangunan memberikan tuntutan pada teknologi bahan material bangunan yang lebih efektif, cepat, ekonomis dan ramah lingkungan. Kondisi tersebut akhirnya menuntut material beton untuk terus dimodifikasi sehingga dapat memenuhi permintaan yang ada. Salah satu upaya dalam meningkatkan kualitas dan kuantitas beton yang dihasilkan adalah dengan memberikan bahan tambah (admixture) pada campuran beton. Consol merupakan bahan tambah (admixture) yang dapat mengurangi air, ada beberapa jenis Consol diantaranya Consol N10 MB yang ramah lingkungan, Consol SG berupa cairan plasticizer beton dengan  efek  memperlambat proses pengeringan. Untuk pemakaian bahan tambah perlu diperhatikan volume takaran yang sesuai dengan rencana. Perancangan beton menggunakan metode Department of Environment (DOE) dengan cetakan sampel berbentuk silinder ukuran diameter 150 mm dan tinggi 300 mm. Persentase penambahan bahan tambah Consol N10 MB, Consol SG  0%, 0,1%, 0,3%, 0,5%, 0,8%, 1%, dan 1,2% serta waktu pengujian tekan beton dilaksanakan pada umur 28 hari.  Hasil Pengujian menunjukkan dengan penambahan Consol N10MB diperoleh peningkatan kuat tekan beton rata-rata hingga 0,3%, dengan nilai kuat tekan beton rata-rata tertinggi sebesar 26,725 MPa. Namun kemudian mengalami penurunan kekuatan tekan beton seiring dengan penambahan persentase Consol N10MB, dengan persamaan yang diperoleh yaitu y = -17,85x2 + 14,63x + 23,16 dengan nilai R2 = 0,983, dan dengan penambahan Consol SG diperoleh peningkatan kuat tekan beton rata-rata seiring dengan penambahan persentase Consol SG hingga penambahan 1,0%, dengan nilai kuat tekan beton rata-rata tertinggi sebesar 46,144 MPa. Namun kemudian mengalami penurunan kekuatan tekan beton pada penambahan 1,2% Consol SG, dengan persamaan yang diperoleh yaitu y = -35,13x2 + 54,03x + 24,43 dengan nilai R2 = 0,927

Grappling with 'Nature' in Australian Home Gardens 1890-1960
Authors: Gaynor Andrea
Published: November 2018

The period from 1890 to 1960 in Australia, as elsewhere, is widely acknowledged as pivotal in the development of modernity, involving increasing urbanisation, commodification, nationalism, state power, bureaucratisation, occupational specialisation, technocratic thinking and faith in
science. This era ushered in a vastly expanded state infrastructure for environmental management, and saw the rise and fall of progressive conservation activism, as well as precursors to the popular environmentalism emerging in the 1960s. Little, however, is known of how typical middle- and
working-class residents of Australian cities and towns understood nature in this period, and how their understandings may have changed in the face of such far-reaching developments. A focus on relationships between people, plants and invertebrates in home garden settings provides one window
onto this issue, providing evidence of how those who gardened negotiated a more or less self-conscious engagement with 'nature' in a domestic setting. Close examination of texts produced by and for gardeners suggests that while the dominant social construction of the relationship between nature
and humans increasingly emphasised human autonomy and control, the embodied experience of home gardening gave rise to diverse understandings. The sense of control and independence that many gardeners had come to expect by the 1950s was challenged by the enduring autonomy of nature, and many
gardeners accepted the limitations of their control. Home gardening thus both reflected and challenged prevailing modernist ideas about emancipation from nature.
Operator estimates for the crushed ice problem
Authors: Khrabustovskyi Andrii , Post Olaf
Published: November 2018

Let [Formula: see text] be the Dirichlet Laplacian in the domain [Formula: see text]. Here [Formula: see text] and [Formula: see text] is a family of tiny identical holes (“ice pieces”) distributed periodically in [Formula: see text] with period ε. We denote by [Formula: see text] the capacity of a single hole. It was known for a long time that [Formula: see text] converges to the operator [Formula: see text] in strong resolvent sense provided the limit [Formula: see text] exists and is finite. In the current contribution we improve this result deriving estimates for the rate of convergence in terms of operator norms. As an application, we establish the uniform convergence of the corresponding semi-groups and (for bounded Ω) an estimate for the difference of the kth eigenvalue of [Formula: see text] and [Formula: see text]. Our proofs relies on an abstract scheme for studying the convergence of operators in varying Hilbert spaces developed previously by the second author.

With the goal of searching effective methods of industrial wastes recycling, filler systems for bituminous binders in road building have been proposed. For the first time in the world, the product of recycled tire rubbers, which is an active powder of discretely devulcanized type of rubber in addition to waste of sulfur produced in technological processes of oil refining, natural gas, etc., have been tested in order to improve the quality of bitumen binders. The rheological properties and fatigue life of the sulfur-bitumen binder have been investigated according to the linear amplitude sweep test (LAS) by using a Smart Pave dynamic shear rheometer (Physica MCR series, Anton Paar, Austria). A technique for preparing samples of sulfur-containing binders has been developed based on the results of photomicrographs analysis obtained by optical microscopy. It has been done to study their fatigue cracking resistance. The analysis of the influence of sulfur and elastic filler on fatigue life has showed that the rise of the quantity of cycles up to fatigue damage of binder samples by the factor of 3-5 (strain of 5% and 2.5%) is due to crumb rubber concentration. The addition of sulfur to ternary systems bitumen/sulfur/elastic filler enables saving energy resources as a result of the possibility of manufacturing sulfur-extended asphalt at lower temperatures.

Effect of No-load and Load Condition on Transformer Sound
Authors: Paghadar Dr. Hitesh
Published: November 2018

Increasing environment noise pollution is a matter of great concern and of late has been attracting public attention. Sound produces the minute oscillatory changes in air pressure and is audible to the human ear when in the frequency range of 20Hz to 20 kHz. The chief sources of audible sound are the magnetic circuit of transformer which produces sound due to magnetostriction phenomenon, vibration of windings, tank and other structural parts, and the noise produced by cooling equipments. This paper presents the validation for sound level measurement scale, why A-weighted scale is accepted for sound level measurement, experimental study carried out on 10MVA Power Transformer. Also presents the outcomes of comparison between No-Load sound & Load sound level measurement, experimental study carried out on different transformer like - 10MVA, 50MVA, 100MVA Power Transformer, to define the dominant factor of transformer sound generation.

Activity of militia on counteracting crime in Ukrainian SSR in the mid-1930s
Authors: Grechenko V. A. , Moskovets V. I.
Published: November 2018

The subject matter of the study is the main aspects of the militia activity of Ukraine on combating crime in the mid-1930s. The novelty of the work is that this problem has not been researched in the historical and legal literature yet.

The authors of the research have used historical, statistical, formal and logical methods. The facts about different directions of militia activities have been generalized. It has been noted that the criminal situation in Ukraine in the 1930s intensified, which became the consequence of the processes of industrialization, solid collectivization, mass dispossession of the kulaks and the Holodomor. Robberies, thefts, bodily harm and murders were widespread in the Republic. The main damage to the state was caused not by the gangs that carried out robberies and attacks on trains, warehouses and shops, but “offenses at the place of work” – large theft of money and goods carried out by the administration, and petty thefts by ordinary workers. Therefore, the fight against crime remained the most important direction of the activities of law enforcement agencies of Ukraine. The attitude towards juvenile delinquency and methods of combating it changed. Penalty policy has shifted from preventive and educational measures to repressive actions against juvenile offenders, who committed crimes. In order to improve the activities of militia, certain attention was paid to improving the work of investigators and district inspectors, covert intelligence and information work, public involvement into countering crime. As a result, it was possible to achieve a certain reduction in the overall level of crime. However, the number of cases of some types of crime (hooliganism) even increased, and new types of crimes (passport forgery) appeared. There was also a politicization of crime, which was a manifestation of the strengthening of the totalitarian regime in the Republic.

The materials of the article can be used for teaching the discipline “History of the State and Law of Ukraine” and the special course “History of Law Enforcement Agencies of Ukraine”.

Specifics of Translation of Emotive Vocabulary (Case study: “Howl's Moving Castle” Novel by Diana Wynne Jones)
Authors: R. Nasibullova Guzel , D. Bimakhanov Talant , Kh. Ashrapova Alsu
Published: November 2018

The expression of an emotional state is a main feature that distinguishes fiction from other literary trends. The problem of emotivity is now among the most discussed issues in anthropocentric linguistics, but despite the researchers’ great attention, many of its aspects are still debatable. In the present research, features of the language transfer of emotions are investigated in the translation of fiction from English into Russian. The novel «Howl’s moving castle» by Diana Wynne Jones (1986) was selected as a material for monitoring the process of translating emotive vocabulary. Authors sought to classify the emotive vocabulary in an artistic work, and also consider and analyze the translation of this lexicon into Russian that was translated by Jones (2013). The following methods were used to solve tasks: A comparative analysis of the translation with original text, and transformational, quantitative, statistical analysis. The theoretical basis of research included classifications of emotive vocabulary that was proposed by Shakhovski (2008), and the classification of emotions by Izard (2007), as well as the classification of translational transformations by Barkhudarov (1975) and Komissarov (1990). The theoretical significance of research lies in the fact that the text emotivity phenomenon is considered according to the comparative linguistics, in general, and the theory of translation in particular. The equivalence of concepts of equivalence and adequacy of translation is justified and clearly demonstrated. The practical value of study is determined by the possibility of applying its results in the artistic translation, in teaching the methodology of translation, in development of didactic manuals on the theory and practice of translation, in the teaching English at senior courses of universities on practical lessons and seminars in special courses.

Published: November 2018

Several centuries have passed, since the birth of traditional educational paradigm comprised of knowledge, abilities, and skills. The world has also changed, and pedagogical systems have remained mostly the same as those at the beginning of their formation, and have also become inadequate for time challenges. This is manifested in the fact that post-industrial or new information society of the 21st century facing the problem of lack of people, who would be able to work in new conditions right after the graduation. The situation when a specialist with a diploma has a finite amount of knowledge in the absence of ability to use it and replenish, becomes a deterrent to the development of the productive forces of society. This is the reason for the appeal of the European, and consequently, the Russian education to the competency building approach. Traditionally, the goals of education were determined by the set of knowledge, abilities, and skills that a graduate must possess. Today, this approach has been proven inadequate. Society needs graduates ready to run active life and capable of solving vital and professional problems occurring. This mainly depends both on received knowledge, abilities, and skills, and also on some additional qualities implying “competence” and “adequacy” that have more in common with modern education goals. To this end, in the experimental part of the study, a model for the formation of professional competencies of university students during the process of implementation of new educational standards was presented.

The Influence of Individual Spirituality Toward Spirit at Work in Enhancing Organizational Commitment and Job Satisfaction
Authors: Indrajaya Amelia Naim
Published: November 2018

The low spirit, lack of higher purpose and meaning in the workplace has an impact towards employees’ morale. Eventually, the commitment to moral will decrease employees’ productivity and organizational commitment at work. Therefore, this study aims to investigate the inluence of individual spirituality toward spirit at work and how it enhances job satisfaction and organizational commitment. The quantitative research through questionnaires was conducted in the branch ofice of PT. Telkom with the highest revenue in the Central of Jakarta. The indings show the importance of workplace spirituality in enhancing job satisfaction and organizational commitments as important factors in increasing company’s performance. Despite the growing belief that workplace spirituality signiicantly relates to performance, the evidence is still needed based on academically proven empirical research that great spirituality is part of the strategic management approach toward better performance. Furthermore, this study supported the hypotheses that individual spirituality is positively impacting spiritat work and in turn positively enhancing job satisfaction and organizational commitment. Further quantitative explanatory approach and/or qualitative exploratory approach will be needed to reach a more solid conclusion.

Published: November 2018

With the growing world ofbusiness, the competition between similar companies getting tighter. To maintain the viability of a company required a good management of resources conducted by the management. Account Receivable turnover and working capital are very important for a company because it is the elements in measuring the proitability of the company. The purpose of this research is to know: (1) the effect of account receivable turnover to company proitability, (2) the effect ofworking capital turnover to the company, (3) the effect of account receivable turnover and working capital turnover to company proitability. The research method used is quantitative analysis, correlation coeficient test, the coeficient of determination test and hypothesis test. The data used in this study is secondary data sourced from inancial statement PT. Merck Tbk period 2009-2013 obtained directly from the respondent. The results based on multiple linear regression tests showed that simultaneously turnover of account receivable and working capital turnover did notsigniicantly affect company proitability (5.603 < 9.55). Partially, the account receivable turnover does not signiicantly affect the proitability of the company (2.298 < 3.182) and the working capital turnover does not signiicantly affect the proitability of the company (3.003 < 3.182). So, it can be said the hypothesis in this study was rejected.
Post-merger and Acquisition Integration: A Case Review of Dial Henkel And BP Amoco
Authors: Mahadewi Lufina
Published: November 2018

Post-merger and Acquisition (M&A) integration often deals with significant transformational changes of merging companies in terms of development, communication, implementation and harmonization of a new shared vision, strategic objective, corporate culture, and also combination of best companies’ value practices. The transformational change is accentuated on facilitating the role of developing and executing an effective post-M&A Integration to build change cohesively with the strategic management of M&A, and also in terms of removing barriers to the success of M&A transaction. The aims of this study are to give a clear and deep understanding on how to manage the soft factors issues that address in M&A process especially in the post-M&A integration process and also to elucidate the critical success factor of M&A process by instilling the best characteristics and the effectiveness level of leadership aspect in M&A. The methodology used in this research is descriptive qualitative research with a method or approach of a case study of Henkel’s Acquisition of The Dial Corporation in 2004. The acquisition of a USA company Dial by a German company Henkel evidenced that both companies were successful in M&A transaction and employed the effectiveness of multi-culture integration strategy. Another case study used in this research is British Petroleum (BP) and American Oil Company (Amoco) (also Atlantic Richield Company (ARCO) and Burmah Castrol) in 1998-2000. The case of BP Amoco showed that the monoculture integration strategy or cultural imposition can also lead to a value creation. Both case studies showed that successful integration requires leadership as a foundation to build a solid execution of post-M&A integration projects in how they planned, communicated and delivered the objectives of the projects.

An Investigation into the Theft of Concentrates and Their Upgrading to Saleable Platinum-Products
Authors: Schouwstra Robert , Mocke Johan , Duncan Michael , Bramdeo Siksha , Scharneck Yolanda
Published: November 2018

Over the years the theft of material from platinum producers has mainly taken place from high-grade areas such as the precious- and base-metal refineries and the converter and smelting operations. At some concentrators, the metallic stream, which concentrated the larger platinum group mineral (PGM) grains using shaking tables (a gravity process), was also at risk due to its high grade. However, the processing of metallics was discontinued many years ago. The relative low grade of concentrator products has led to the belief that the concentrators are a low-risk area for theft. The final products are still very diluted by the gangue minerals, and to recover and purify the various metals contained in these products requires costly processing techniques (i.e., smelting and refining). High-grade stolen products are generally offered to small refineries who either further process, and package, or directly ship the material overseas for refining. In the case of stolen concentrates, the volume and value of the material would make that an unprofitable option. This assumption, as well as the risk the thieves run of being caught while removing large quantities of material from the concentrators, has resulted in management considering theft from concentrators of lesser importance than theft from the smelters or refineries. However, over the past few years investigations by protection services at concentrators have shown that high-grade platinum products are smuggled off-site. These products have been found on the concentrator as well as at illegal smelthouses where these type of products are processed further. Forensic investigations indicated that these upgraded products are much higher in grade than the normal concentrator products, characterised by high platinum contents, and contain high-density minerals such as galena (lead sulphide) and chromite. This suggests that these materials are significantly upgraded prior to smuggling these out of the operations. The method used by the perpetrators results in much of the value minerals being discarded, giving rise to concentrates that are atypical of Bushveld products. To better understand the process of upgrading these products and to get more information for the ‘fingerprinting’ database on the ‘at-risk products’, concentrator products were obtained from areas where material is stolen for further upgrading. This paper describes the upgrading process used by the illegal ‘processors’ and discusses the mineralogy and chemistry of the various products down the illegal processing chain. The study indicates that products containing coarse, liberated platinum-group minerals are the most favorable for upgrading. Flotation products with high precious metal grades and low chromite contents are preferred by the syndicate members. These are typically the first cells of the rougher banks, final concentrates, and the various cleaners and re-cleaners feeding into the final concentrates.

Ensuring an adequate and safe access to sanitation is essential to prevent diseases. Using provincial spatial panel data reported in the China Health Statistical Yearbook and the China Statistical Yearbook, this paper analyzed the spatio-temporal characteristics of improved rural sanitation in 30 Chinese provinces during the period 2006–2015, and analyzed factors that may affect improved sanitation rates in rural China. Spatial autocorrelations of improved sanitation rates were computed via Global and Local Moran’s I firstly, and then, inter-provincial disparities of improved sanitation were assessed by using the Theil index estimator; finally, the spatial panel model was employed to examine the potential socio-economic factors. Spatial autocorrelations results suggested that the provincial improved sanitation rates changes affect both the provinces themselves and the adjacent regions; Analysis of the spatial panel model revealed that factors such as GDP per capita, investment proportion ratio, centralized water supply, rural residents’ expenditure were positively associated with improved sanitation rates, and illiteracy rate of people older than 15 was negatively related with improved sanitation rates. Socio-economic factors had affected the improved sanitation rates in 30 provinces in rural China. Thus, a series of policies, socio-economic measures and personal latrine literacy education should be given to improve the status of improved sanitation rates in rural China.

The main purpose of the study was to explore the associations of sleep duration and sleep quality with physical activity (PA). In this cross-sectional study, participants were 894 elderly individuals (mean age 80 ± 3 years; 56.0% women) living in nursing homes. PA, sleep duration, and sleep quality (based on the Pittsburgh Sleep Quality Index (PSQI)) were self-reported. The associations of sleep duration and sleep quality with PA at the nursing home level were analyzed using generalized estimating equations with clustering. Participants reporting short sleep duration (<6 h; OR = 0.45; 95% CI 0.25–0.80) were less likely to report sufficient PA, yet those reporting long sleep duration (>9 h; OR = 2.61; 95% CI 1.35–5.02) and good sleep quality (<5 points; OR = 1.59; 95% CI 1.19–2.12) were more likely to report sufficient PA. When sleep duration and sleep quality were entered into the same model, the same associations remained. This study shows that elderly individuals who report short sleep duration are less likely to meet PA guidelines, while those who report long sleep duration and good sleep quality are more likely to meet PA guidelines. Strategies aiming to improve sleep duration and sleep quality are warranted.
A Raster-Based Subdividing Indicator to Map Urban Heat Vulnerability: A Case Study in Sydney, Australia
Authors: Zhang Wei , McManus Phil , Duncan Elizabeth
Published: November 2018

Assessing and mapping urban heat vulnerability has developed significantly over the past decade. Many studies have mapped urban heat vulnerability with a census unit-based general indicator (CGI). However, this kind of indicator has many problems, such as inaccurate assessment results and lacking comparability among different studies. This paper seeks to address this research gap and proposes a raster-based subdividing indicator to map urban heat vulnerability. We created a raster-based subdividing indicator (RSI) to map urban heat vulnerability from 3 aspects: exposure, sensitivity and adaptive capacity. We applied and compared it with a raster-based general indicator (RGI) and a census unit-based general indicator (CGI) in Sydney, Australia. Spatial statistics and analysis were used to investigate the performance among those three indicators. The results indicate that: (1) compared with the RSI framework, 67.54% of very high heat vulnerability pixels were ignored in the RGI framework; and up to 83.63% of very high heat vulnerability pixels were ignored in the CGI framework; (2) Compared with the previous CGI framework, a RSI framework has many advantages. These include more accurate results, more flexible model structure, and higher comparability among different studies. This study recommends using a RSI framework to map urban heat vulnerability in the future.

Previous research suggests that the economic crisis can affect mental health. The purpose of this study was to analyse the association of risk of poor mental health with various socioeconomic, demographic, health, quality of life, and social support variables; and to evaluate the contribution of socioeconomic variables most affected by the beginning of the economic crisis (employment situation and income) on the changes in the prevalence of the risk of poor mental health between 2005 and 2010. A study of prevalence evolution in adult population residents of the Valencian Community in the Spanish Mediterranean was conducted. We studied 5781 subjects in 2005 and 3479 in 2010. Logistic regression models have been adjusted to analyse the association between variables. A standardisation procedure was carried out to evaluate which part of the changes in overall prevalence could be attributed to variations in the population structure by age, sex, employment status, and income between the years under study. The prevalence of GHQ+ increased from 2005 to 2010, in both men and women. Several variables were closely associated with the risk of poor mental health (sex, age, country of birth, number of nonmental chronic diseases, social support, disability, cohabitation in couple, employment status, and income). The changes produced as a result of the onset of the economic crisis in income and unemployment (increase in low income and in unemployment rates) contributed to the increase of poor mental health risk. This could confirm the sensitivity of mental health to the economic deterioration caused by the crisis.

Accurate mapping of weed distribution within a field is a first step towards effective weed management. The aim of this work was to improve the mapping of milk thistle (Silybum marianum) weed patches through unmanned aerial vehicle (UAV) images using auxiliary layers of information, such as spatial texture and estimated vegetation height from the UAV digital surface model. UAV multispectral images acquired in the visible and near-infrared parts of the spectrum were used as the main source of data, together with texture that was estimated for the image bands using a local variance filter. The digital surface model was created from structure from motion algorithms using the UAV image stereopairs. From this layer, the terrain elevation was estimated using a focal minimum filter followed by a low-pass filter. The plant height was computed by subtracting the terrain elevation from the digital surface model. Three classification algorithms (maximum likelihood, minimum distance and an object-based image classifier) were used to identify S. marianum from other vegetation using various combinations of inputs: image bands, texture and plant height. The resulting weed distribution maps were evaluated for their accuracy using field-surveyed data. Both texture and plant height have helped improve the accuracy of classification of S. marianum weed, increasing the overall accuracy of classification from 70% to 87% in 2015, and from 82% to 95% in 2016. Thus, as texture is easier to compute than plant height from a digital surface model, it may be preferable to be used in future weed mapping applications.
Incorporating Credit Quality in Bank Efficiency Measurements: A Directional Distance Function Approach
Authors: Qayyum Abdul , Riaz Khalid
Published: November 2018

The objective of the study was to measure the risk-adjusted efficiency of banks in 24 emerging economies for the period of 1999–2013. A two-stage network data envelopment analysis (DEA), with separate deposit mobilization and loan financing stages was used. Efficiency was measured using directional distance functions with DEA, featuring non-performing loans as undesirable outputs. The distributions of efficiency scores were different when credit quality was taken into account. The distribution of efficiency scores varied systematically with accumulation of non-performing loans across regions. The financial crisis of 2007–2008 impacted more adversely the regions that had higher proportions of non-performing loans in banks’ portfolios. The results of a follow-on non-parametric regression showed that smaller, better capitalized, and private banks were more efficient. The conditions conducive for high levels of technical efficiency by banks were found to be characterized by economic growth and low inflation.
Noise–Seeded Developmental Pattern Formation in Filamentous Cyanobacteria

Published: November 2018

Under nitrogen-poor conditions, multicellular cyanobacteria such as Anabaena sp. PCC 7120 undergo a process of differentiation, forming nearly regular, developmental patterns of individual nitrogen-fixing cells, called heterocysts, interspersed between intervals of vegetative cells that carry out photosynthesis. Developmental pattern formation is mediated by morphogen species that can act as activators and inhibitors, some of which can diffuse along filaments. We survey the limitations of the classical, deterministic Turing mechanism that has been often invoked to explain pattern formation in these systems, and then, focusing on a simpler system governed by birth-death processes, we illustrate pedagogically a recently proposed paradigm that provides a much more robust description of pattern formation: stochastic Turing patterns. We emphasize the essential role that cell-to-cell differences in molecular numbers—caused by inevitable fluctuations in gene expression—play, the so called demographic noise, in seeding the formation of stochastic Turing patterns over a much larger region of parameter space, compared to their deterministic counterparts.

In this paper, a series of Na2SO4·10H2O–KCl eutectic mixtures were prepared by adding different mass fractions of KCl (1 wt.%, 3 wt.%, 5 wt.%, or 7 wt.%) to Na2SO4·10H2O. Polyacrylamide (PAM) was proposed as the thickener, sodium tetraborate decahydrate (STD) was proposed as the nucleating agent, and expanded graphite (EG) was proposed as the high thermal conductivity medium for Na2SO4·10H2O–5 wt.% KCl eutectics. The results showed that in Na2SO4·10H2O–5 wt.% KCl eutectics with 5 wt.% PAM and 5 wt.% STD, almost no phase separation occurred, and the degree of supercooling was reduced to 0.4 °C. The thermal performance of Na2SO4·10H2O–5 wt.% KCl composite phase change materials (CPCMs) with varying contents of EG was explored. The results showed that EG could improve the thermal conductivity effectively and that the mass fraction of EG should be no more than 3%, otherwise the crystallization value and supercooling would deteriorate. The thermal reliability of the Na2SO4·10H2O–5 wt.% KCl eutectic CPCMs containing 5 wt.% PAM, 5 wt.% STD, and 3 wt.% EG was investigated, mainly through the ambient temperature, thermal cycling test, and TGA analysis. The results demonstrated that these CPCMs showed perfect thermal reliability.

Titanium implant surface modifications have been widely investigated to favor the process of osseointegration. The present work aimed to evaluate the effect of sphene (CaTiSiO5) biocoating, on titanium substrates, on the in vitro osteogenic differentiation of Human Adipose-Derived Stem Cells (hADSCs). Sphene bioceramic coatings were prepared using preceramic polymers and nano-sized active fillers and deposited by spray coating. Scanning Electron Microscopy (SEM) analysis, surface roughness measurements and X-ray diffraction analysis were performed. The chemical stability of the coatings in Tris-HCl solution was investigated. In vitro studies were performed by means of proliferation test of hADSCs seeded on coated and uncoated samples after 21 days. Methyl Thiazolyl-Tetrazolium (MTT) test and immunofluorescent staining with phalloidin confirmed the in vitro biocompatibility of both substrates. In vitro osteogenic differentiation of the cells was evaluated using Alizarin Red S staining and quantification assay and real-time PCR (Polymerase Chain Reaction). When hADSCs were cultured in the presence of Osteogenic Differentiation Medium, a significantly higher accumulation of calcium deposits onto the sphene-coated surfaces than on uncoated controls was detected. Osteogenic differentiation on both samples was confirmed by PCR. The proposed coating seems to be promising for dental and orthopedic implants, in terms of composition and deposition technology.
