Authors: Sheng Bo , Huang Liang , Wang Xiangbin , Zhuang Jie , Tang Lihua , Deng Chao , Zhang Yanxin
Published: February 2019

BACKGROUND

Early identification of knee osteoarthritis (OA) can improve treatment outcomes and reduce medical costs. However, there are major limitations among existing classification or prediction models, including abstract data processing and complicated dataset attributes, which hinder their applications in clinical practice.

OBJECTIVE

The aim of this study was to propose a Bayesian network (BN)–based classification model to classify people with knee OA. The proposed model can be treated as a prescreening tool, which can provide decision support for health professionals.

METHODS

The proposed model’s structure was based on a 3-level BN structure and then retrained by the Bayesian Search (BS) learning algorithm. The model’s parameters were determined by the expectation-maximization algorithm. The used dataset included backgrounds, the target disease, and predictors. The performance of the model was evaluated based on classification accuracy, area under the curve (AUC), specificity, sensitivity, positive predictive value (PPV), and negative predictive value (NPV); it was also compared with other well-known classification models. A test was also performed to explore whether physical fitness tests could improve the performance of the proposed model.

RESULTS

A total of 249 elderly people between the ages of 60 and 80 years, living in the Kongjiang community (Shanghai), were recruited from April to September 2007. A total of 157 instances were adopted as the dataset after data preprocessing. The experimental results showed that the results of the proposed model were higher than, or equal to, the mean scores of other classification models: .754 for accuracy, .78 for AUC, .78 for specificity, and .73 for sensitivity. The proposed model provided .45 for PPV and .92 for NPV at the prevalence of 20%. The proposed model also showed a significant improvement when compared with the traditional BN model: 6.3% increase in accuracy (from .709 to .754), 4.0% increase in AUC (from .75 to .78), 6.8% increase in specificity (from .73 to .78), 5.8% increase in sensitivity (from .69 to .73), 15.4% increase in PPV (from .39 to .45), and 2.2% increase in NPV (from .90 to .92). Furthermore, the test results showed that the performance of the proposed model could be largely enhanced through physical fitness tests in 3 evaluation indices: 10.6% increase in accuracy (from .682 to .754), 16.4% increase in AUC (from .67 to .78), and 30.0% increase in specificity (from .60 to .78).

CONCLUSIONS

The proposed model presents a promising method to classify people with knee OA when compared with other classification models and the traditional BN model. It could be implemented in clinical practice as a prescreening tool for knee OA, which would not only improve the quality of health care for elderly people but also reduce overall medical costs.

Published: February 2019

BACKGROUND

Recent studies indicate that exercise-related games can improve executive function, attention processing, and visuospatial skills.

OBJECTIVE

This study investigates whether exercise with exergame can improve the executive function in patients with metabolic syndrome (MetS).

METHODS

Twenty-two MetS patients were recruited and randomly assigned to the exergame group (EXG) and treadmill group. The reaction time (RT) and electrophysiological signal from the frontal (Fz), central (Cz), and parietal (Pz) cortex were collected during a Stroop task after 12 weeks’ exercise.

RESULTS

During the Stroop congruence (facilitation) judgment task, both EXG and TEG showed significantly faster RT after 12 weeks of exercise training. For N200 amplitude, EXG significantly increased on Fz and Cz. These changes were significantly larger in EXG than TEG. For P300 amplitude, EXG significantly increased on Fz, Cz, and Pz, while TEG significantly increased on Cz and Pz only. During the Stroop incongruence (interference) judgment task, both EXG and TEG showed significantly faster RT. For P300 amplitude, EXG significantly increased on Fz and Cz only, while TEG significantly increased on Fz, Cz, and Pz.

CONCLUSIONS

Exergaming improves executive function in patients with MetS as much as normal aerobic exercise. Particularly, the unique benefit of the exergame beyond increased aerobic capacity is the improvement of selective attention among cognitive functions. Thus, exergaming could be recommended to someone who needs to improve brain responses of concentration and judgment as well as physical fitness.
Medication Management Models for Polymedicated Home-Dwelling Older Adults With Multiple Chronic Conditions: Protocol of a Systematic Review (Preprint)
Authors: Pereira Filipa , Roux Pauline , Rosselet Amoussou Joëlle , Martins Maria Manuela , Von Gunten Armin , Verloo Henk
Published: February 2019

BACKGROUND

Older adults with multiple chronic diseases commonly require complex medication regimes. When combined with frailty, cognitive impairment, and changing pharmacological prescriptions, older adults’ polymedication regimes increase the risk of medication-related problems (MRPs) and hospitalization. Effective, well-organized medication management could avoid MRPs and their clinical outcomes.

OBJECTIVE

Identify medication management models and analyze their impact on managing and preventing MRPs for polymedicated, home-dwelling older adults.

METHODS

We will conduct a systematic review of published articles in relevant professional scientific journals from inception until March 31, 2019, in the following electronic databases,: Embase; Medline OvidSP; PubMed (NOT Medline[sb]); Cumulative Index to Nursing and Allied Health Literature (CINAHL) EBSCO; PsycINFO OvidSP; Cochrane Library, Wiley; and Web of Science. We will also hand search the bibliographies of all the relevant articles found and search for unpublished studies. We will consider publications in English, French, German, Spanish, Italian, and Portuguese. Retrieved articles will be screened for eligibility. Statistical analyses will be conducted following the recommendations of the Cochrane Handbook for Systematic Reviews of Interventions, the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), and Meta-analysis Of Observational Studies in Epidemiology (MOOSE) statements. Data will be analyzed using SPSS Statistics for Windows, version 25.0 (IBM Corp), and Review Manager, version 5.5 (The Nordic Cochrane Centre, The Cochrane Collaboration).

RESULTS

A preliminary search in Embase delivered 3272 references. This preliminary search allows us to complete our research strategy with equation development and to search the other databases. Relevant articles identified will allow for searching the reference lists for unpublished studies. The inclusion and exclusion criteria will be rigorously respected in the study selection. The entire study is expected to be completed by January 2020.

CONCLUSIONS

This review will provide an exhaustive view of medication management models that could be effective for polymedicated, home-dwelling older adults and will allow us to analyze their impact on managing and preventing MRPs.

Authors: Jin Xiao-Ling , Zhang Miao , Zhou Zhongyun , Yu Xiaoyu
Published: February 2019

BACKGROUND

The rapid development of genetic and genomic technologies, such as next-generation sequencing and genome editing, has made disease treatment much more precise and effective. The technologies’ value can only be realized by the aggregation and analysis of people’s genomic and health data. However, the collection and sharing of genomic data has many obstacles, including low data quality, information islands, tampering distortions, missing records, leaking of private data, and gray data transactions.

OBJECTIVE

This study aimed to prove that emerging blockchain technology provides a solution for the protection and management of sensitive personal genomic data because of its decentralization, traceability, encryption algorithms, and antitampering features.

METHODS

This paper describes the case of a blockchain-based genomic big data platform, LifeCODE.ai, to illustrate the means by which blockchain enables the storage and management of genomic data from the perspectives of data ownership, data sharing, and data security.

RESULTS

Blockchain opens up new avenues for dealing with data ownership, data sharing, and data security issues in genomic big data platforms and realizes the psychological empowerment of individuals in the platform.

CONCLUSIONS

The blockchain platform provides new possibilities for the management and security of genetic data and can help realize the psychological empowerment of individuals in the process, and consequently, the effects of data self-governance, incentive-sharing, and security improvement can be achieved. However, there are still some problems in the blockchain that have not been solved, and which require continuous in-depth research and innovation in the future.
Building a Secure Biomedical Data Sharing Decentralized App (DApp): Tutorial (Preprint)
Authors: Johnson Matthew , Jones Michael , Shervey Mark , Dudley Joel T , Zimmerman Noah
Published: February 2019

UNSTRUCTURED

Decentralized applications (DApps) are computer programs that run on a distributed computing system, such as a blockchain network. Unlike the client-server architecture that powers most internet applications, DApps that are integrated with a blockchain network can execute application logic that is guaranteed to be transparent, verifiable, and immutable. This new paradigm has a number of unique properties that are attractive to the biomedical and health care communities. However, instructional resources are scarcely available for biomedical software developers to begin building DApps on a blockchain. Such applications require new ways of thinking about how to build, maintain, and deploy software. This tutorial serves as a complete working prototype of a DApp, motivated by a real use case in biomedical research requiring data privacy. We describe the architecture of a DApp, the implementation details of a smart contract, a sample iPhone operating system (iOS) DApp that interacts with the smart contract, and the development tools and libraries necessary to get started. The code necessary to recreate the application is publicly available.
The Effect of a Drying Time and The Different of Storage Periods to The Quality and The Shelflife of Milkfish (Chanos chanos forsk.) Cooked by High-Pressure Cooker
Authors: Agustiari Nurul Meutia , Ibrahim Ratna , Surti Titi
Published: February 2019

Milkfish that have been seasoned with some spices then cooked by a high -cooker produced a fish product which has soft spines and bones. The product which has a local name bandeng presto has been popular in Indonesia due to the product is tasty and it is easier to be consumed directly after it is prepared as a dish. The storage life of bandeng presto is relatively short, which is due to deterioration process by microbes after processing. Consequently, this condition can retard the products distribution. The aims of the research are to understand is there any significant influence of differing the drying time (0 hours and 4 hours) of milkfish cooked by a high-pressure cooker by using an electric oven (50oC) and storage period at room temperature (5 days) and also to find out which treatment produce the best product quality. The results showed that the treatment of differing the drying period gave a highly significant influence (P <0.01) on the sensory value and the moisture content but did not gave significant influence (P >0.05) on the number of bacteria colonies. The length of storage period gave a highly significant influence (P <0.01) on the sensory value between the products which were dried for 4 hours and without drying treatment but only the drying process for 4 hours gave a highly significant influence (P <0.01) on the moisture content, the water activity and the number of bacteria colonies. The quality of the products that were dried for 4 hours were better and their storage life can reach up to 3 days compared to the products that were not dried.Keywords: Milkfish, high pressure cooker, drying, oven, quality, storage life
Review: Prevention and Reduction of Mycotoxin by Antagonistic Microorganism
Authors: Rahayu Winiati Pudji
Published: February 2019

Mycotoxin is widely known as one cause of foodborne disease, produced by toxigenic fungi. Any country should be aware about this high risk potency by knowing the mycotoxin, affected commodities, fungal sources, and toxicity effect to human or animal. Controlling mycotoxin could be done by physic, chemical, and biological methods. The microbial characteristic used for biological agent should be evaluated including the inability to produce toxic substance, tendency to multiply, colonize, survive, safety, and applicability to the environment. Studies related to mycotoxin biocontrol by using antagonistic microorganism can be focused on (1) the effect to the mycotoxin, (2) the growth of microorganism, or (3) the application to food both raw material and processed products. Consideration to combine more than one species of microorganism instead of a single species also has been taken to achieve more effective result.  For example, S. cerevisiae has been used together with LAB to control certain mycotoxin. Further studies are needed to develop the possibility of other biological agents and the effect of their application, which in the next have the potency as manufacturing products.

Authors: Prastowo Bambang Nurcahyo , Putro Nur Achmad Sulistyo , Dhewa Oktaf Agni
Published: February 2019

Instant messaging services usually integrate a notification system on their users’ devices, as phone calls and short message service (SMS) systems do. Telegram is – as far as we are aware – the only popular instant messaging service that uses open source code. Telegram also provides APIs for their users, enabling the development of a bot system that allows instant messaging application to access information. Here, we study the potential use of Telegram bot as a user interface to a paperless office (PLO) system developed in our institution. We found that Telegram bot improves communication among the users; however, as the amount of messages increased, the server becomes overloaded. This limitation suggests that future works need to be directed to improving the efficiency of the bot
Adaptive Moment Estimation On Deep Belief Network For Rupiah Currency Forecasting
Authors: Prabowo Abram Setyo , Sihabuddin Agus , SN Azhari
Published: February 2019

One approach that is often used in forecasting is artificial neural networks (ANN), but ANNs have problems in determining the initial weight value between connections, a long time to reach convergent, and minimum local problems.Deep Belief Network (DBN) model is proposed to improve ANN's ability to forecast exchange rates. DBN is composed of a Restricted Boltzmann Machine (RBM) stack. The DBN structure is optimally determined through experiments. The Adam method is applied to accelerate learning in DBN because it is able to achieve good results quickly compared to other stochastic optimization methods such as Stochastic Gradient Descent (SGD) by maintaining the level of learning for each parameter.Tests are carried out on USD / IDR daily exchange rate data and four evaluation criteria are adopted to evaluate the performance of the proposed method. The DBN-Adam model produces RMSE 59.0635004, MAE 46.406739, MAPE 0.34652. DBN-Adam is also able to reach the point of convergence quickly, where this result is able to outperform the DBN-SGD model.
From Social Trust and Happiness to Government Trust: The Moderating Role of Political Systems and Governance in the Philippines
Authors: Calata Erickson D , Ugaddan Reginald G.
Published: February 2019

There are frequent calls to enhance citizens' trust in government to pave the way towards a new paradigm of participatory governance and strong citizen support for government. In various realms, citizens may directly or indirectly engage with the government through various available mediums, even though, despite the availability of various policies and services provided by the government, citizens are generally passive and adamant in trusting the public sector. While many studies have explored a set of determinants that influence citizens' trust in government (i.e., central government, local government, parliament, and the legal system), few studies have ascertained the relationship and the role of social trust, happiness, governance, and political systems. These are critical factors that may influence trust in government. To address this gap, this study draws on the theoretical lens of social capital theory, proposing that cognitive social trust and citizen happiness—environment and performance—are the most likely predictors of citizen trust in government. This study assumes that citizens' perceptions of governance and political systems will moderate the effect of social trust and happiness on trust in government. Using data from the Asia Barometer Survey 2007, and focusing on data collected from the Philippines, this study tests a latent model employing the structural equation modelling technique. It finds that happiness negatively predicts trust in the central government and the legal system, while all other predictors do not have a significant effect. The findings also show that the political system moderates the impact of social trust and happiness on trust in government. Finally, this article points out its theoretical, empirical, and practical implications and provides directions for future research.
Entre o prescrito e o vivido: o PROEJA no Instituto Federal de Educação, Ciência e Tecnologia de Goiás - Campus de Formosa (2010-2015)
Authors: Brito Roberta Gama , Muñoz Palafox Gabriel Humberto
Published: February 2019

O presente artigo é resultado da dissertação em nível de mestrado que teve como objetivo analisar a implantação e implementação do Proeja no Instituto Federal de Educação, Ciência e Tecnologia de Goiás – Campus de Formosa (2010-2015). O estudo é orientado pela abordagem do Materialismo Histórico-Dialético (MARX;ENGELS, 2007). Os resultados apontaram que a implementação do PROEJA no IFG-Campus de Formosa seguiu a lógica da escolarização para o trabalho. Outra questão evidenciada refere-se à ausência de espaços de diálogos/discussões na Instituição, o que impede os agentes sociais de realizar momentos de reflexões críticas acerca do programa. Diante dos limites e contradições evidenciados no processo de implementação do PROEJA no estudo, acredita-se que a Instituição deve assumir a política do PROEJA como uma proposta de educação capaz de contribuir com a superação de entraves ideológicos e de processos de gestão verticalizados presentes na condução das políticas públicas educacionais.
Decolonialidade e interculturalidade: pressupostos teórico-metodológicos para a educação das relações étnicorraciais no ensino de História

Published: February 2019

Este artigo é fragmento oriundo da dissertação desenvolvida no Programa de Mestrado Profissional em Ensino de História – Profhistória da Universidade Federal de Santa Catarina como o título A educação para as relações étnicorraciais e o ensino de história: memórias e experiências de docentes da educação básica. Neste recorte apresentamos um diálogo com os documentos legais para o Ensino de História e Cultura Afro-brasileira e Africana. Dentre outros destacamos a Lei 10.639/2003 que trata da obrigatoriedade do ensino de história e cultura afro-brasileira e africana nas escolas, as Diretrizes Curriculares Nacionais para a Educação das Relações Étnicorraciais – Dcneer. Para análise nos pautamos na decolonialidade (do poder, do saber, do ser) como uma possibilidade epistemológica radical para o rompimento com os saberes eurocêntricos e numa nova metodologia e práticas pedagógicas fundamentadas na interculturalidade. Focamos de forma particular como o ensino de história poderá contribuir para gerar questionamentos, problematizações e aberturas para se ensinar para além da história dos povos europeus ou histórias narradas de forma colonizadora com modelos europeus.
Fault-tolerant gates via homological product codes
Authors: Jochym-O'Connor Tomas
Published: February 2019

A method for the implementation of a universal set of fault-tolerant logical gates is presented using homological product codes. In particular, it is shown that one can fault-tolerantly map between different encoded representations of a given logical state, enabling the application of different classes of transversal gates belonging to the underlying quantum codes. This allows for the circumvention of no-go results pertaining to universal sets of transversal gates and provides a general scheme for fault-tolerant computation while keeping the stabilizer generators of the code sparse.
MODELAGEM MATEMÁTICA DA DECOMPOSIÇÃO DA SERAPILHEIRA EM UM ESTADO TRANSIENTE DE REFLORESTAMENTO
Authors: Orth Arlete Cherobini , Coelho Geraldo Ceni , Borges Pedro Augusto Pereira
Published: February 2019

Constatou-se que a serapilheira é formada por todo o material biológico depositado sobre o solo, sendo composto basicamente por folhas, cascas, frutos e ramos. A decomposição da serapilheira e a consequente incorporação de matéria orgânica e nutrientes minerais ao solo, são processos importantes em sistemas agroflorestais e florestas em recuperação de ecossistemas degradados. Neste trabalho foram desenvolvidos dois modelos matemáticos: um para descrever a variação do fator de decomposição da serapilheira em função do tempo, com base em dados experimentais; e outro para prever a decomposição e o acúmulo de serapilheira em um sistema florestal transiente, com dados empíricos de plantios de grandiúva (Trema micrantha (L.) Blume) e aroeira-periquita (Schinus molle L.). Foram obtidos três formas de dados experimentais: a massa que compõem a serapilheira (Xo); a variação da massa em decomposição (X), a variação do fator de decomposição (k). O modelo de serapilheira remanescente, para um caso transiente com entrada de massa, envolve três grandes variáveis relacionadas entre si: o crescimento das árvores, a decomposição da serapilheira e a massa Xo de entrada. As seguintes premissas orientam a formulação do modelo: 1. A entrada de massa na serapilheira (Xo) ocorre em porções, cada uma em um instante de tempo; 2. A massa de serapilheira acumulada em um determinado instante de tempo é composta por n frações (Xi), cada qual em um estágio de decomposição diferente,  portanto com um valor de k correspondente;  3. Os valores do fator de decomposição variam de forma contínua. O aumento da produção de serapilheira mensal foi considerado como uma função do crescimento da população das árvores. Foram efetivadas comparações entre os resultados dos modelos com dados experimentais, especialmente no que se refere à massa de serapilheira remanescente. Os modelos foram utilizados para simular o acúmulo de serapilheira ao longo do tempo de vida das árvores. Em suma, verificou-se ainda que, o processo de decomposição do material biológico produzido pelas espécies em comento, bem como toda e qualquer matéria orgânica existente sobre o solo, está em constante processo de decomposição, portanto com tempo finito, não se coadunando com relatos superficiais de estudos, declarando que a partir de certo tempo de implantação das florestas, este processo ser infinito.
A VULNERABILIDADE DOS PROFISSIONAIS DE ENFERMAGEM FRENTE AOS RISCOS BIOLÓGICOS: UM ESTUDO EM SALA DE EMERGÊNCIA
Authors: Santos Michelle Queiroz dos , Leite Jandra Cibele Rodrigues de Abrantes Pereira
Published: February 2019

O ambiente hospitalar tem sido considerado insalubre e oferece riscos de acidentes e doenças, principalmente, para os trabalhadores de Enfermagem que estão expostos a vários riscos ocupacionais, entre eles, o risco biológico. O objetivo geral do estudo foi identificar a vulnerabilidade dos profissionais de Enfermagem frente aos riscos biológicos e a relevância do risco de adquirir patologias como HIV/AIDS, Hepatite B e C. Trata-se de um estudo descritivo exploratório com abordagem quantitativa, realizado de setembro a novembro de 2016 na Sala de Emergência (SE) do HJPII. Nesse período, foram acompanhados cinco enfermeiros e vinte e três técnicos de enfermagem totalizando 28 profissionais. A coleta de dados se deu através de observação sistemática e aplicação de um questionário, com perguntas fechadas e abertas, divididas em duas partes: Dados de identificação e Riscos Ocupacionais. Os dados sociodemográficos evidenciam que a equipe de enfermagem é predominantemente feminina e possuem mais de um vínculo empregatício. Os dados relacionados aos riscos ocupacionais evidenciam o ambiente estressante e sobrecarga de trabalho como principais fatores de risco psicossocial. Quanto aos riscos biológicos, 100% dos profissionais admitiram exposição à infeções e doenças, bem como 92,9% assumiram estar expostos a sangue, fluídos e secreções. Os resultados relacionados aos riscos físicos revelam que o item com maior porcentagem foi o estresse onde 100% dos profissionais revelaram ter no ambiente de trabalho. A frequência do uso de EPI apresenta resultado contraditório com a observação realizada em campo, tendo em vista que os profissionais referem utilizá-los frequentemente e a observa mostrou que a utilização de EPI nem sempre acontece nas situações de exposição. Observa-se notoriamente que as dificuldades de aceitação e cumprimento de medidas preventivas são fatores existentes e, por isso, preocupantes, evidenciando assim a necessidade de reavaliar as atividades de educação permanente no cenário do estudo, com a proposta de abordagens que permitam a construção de um conhecimento capaz de modificar a prática desses profissionais mediante a observância dos fatores que interferem na adesão ao equipamento de proteção individual.

Através da análise dos dados conclui-se que a maioria dos casos ocorreu em pacientes do sexo masculino, representando 86% (927) dos casos em idade produtiva, estando relacionado ao padrão epidemiológico ocupacional. A lesão cutânea foi a forma predominante, ocorrendo em 90% (969) dos casos e, em 95% dos casos, o critério de confirmação foi o diagnóstico clínico-laboratorial. Em relação aos casos notificados no período estudado, a maioria evoluiu para a cura (60,5%). A LT possui uma prevalência considerável na região estudada, fazendo-se necessários maiores investimentos e estudos para viabilizar ações preventivas, o diagnóstico precoce e o tratamento, oferecendo assim uma possível melhoria na qualidade de vida dessa população.
Colorimetric (CIEDE2000) comparison between two shade guides used for visual evaluation of tooth whitening efficacy
Authors: Paravina Rade , Pereira-Sanchez Natalie , Ghinea Razvan , Powers John
Published: February 2019

Introduction/Objective. The objective of this study was to perform colorimetric comparison between two shade guides used for visual tooth whitening monitoring. Methods. VITA Bleachedguide 3D-Master (BG) and value scale of VITA classical A1?D4 (VC) were evaluated (n = 3) using a non-contact spectroradiometer. Ranges, distribution, and correlation among color parameters were evaluated using CIEDE2000 color difference formula. In addition, optimized whiteness index for dentistry (WID), and Yellowness Index E313 (YI) were analyzed. ANOVA and Fisher?s PLSD test at a 0.05 level of significance were used in statistical analysis. Results. The lightness (L?), chroma (C?), and hue (h?) ranges for BG were 20.4, 25.9, and 19.1, respectively. The corresponding ranges for VC were 15.3, 10.9, and 20.6. R2 values for individual color coordinate/tab arrangement were higher for BG than VC. The same is true for R2 values of pairs of color coordinates for BG/VC: L?C? = 0.89/0.33, L?h? = 0.88/0.53, and C?h? = 0.70/0.51. BG also exhibited better agreement between the manufacturer?s tab arrangement with ?E?, WID and YI. The ?E? between the lightest and the darkest BG and VC tab were 20.6 and 13.2, respectively. The average ?E? among the adjacent tabs were 1.9 (0.5) for BG (corresponding to two shade guide units, SGU) and 3.0 (1.0) for VC (1 SGU). Conclusion. VITA Bleachedguide 3D-Master exhibited wider L?, C?, ?E?, WID, and YI ranges compared to value scale of VITA classical A1?D4 shade guide and better distribution of evaluated color parameters. This, along with the presence of several shades lighter than B1 of VC, recommends the use of BG for visual evaluation of tooth whitening efficacy.
The influence of air side and fuel side water addition on engine’s behaviour of a biofuel based compresion ingnition engine under oxygen enriched combustion
Authors: Masimalai Senthilkumar
Published: February 2019

The effect of water injection at the air side and water addition at fuel side on engine?s performance of a Diesel engine was studied under oxygen enriched intake air using neat mahua oil as fuel. Initially experiments were carried out using neat mahua oil as fuel with different oxygen concentrations such as 21% (ambient), 22.4%, 23.8%, and 24.7% by volume at the air side. The optimal oxygen concentration was found based on the engine?s brake thermal efficiency. At the optimal oxygen concentration water injection was done on air side at 4% by mass and the experiments were repeated with neat mahua oil as fuel under oxygen enrichment mode. Finally, mahua oil emulsion was prepared using the same amount of water (i. e. 4%) and tested in the engine. A comparative study was made for the same amount of water (i. e. 4% as optimal) for water injection and neat mahua oil emulsion on engines behavior. Oxygen enrichment increased the brake thermal efficiency with all concentrations and reached the maximum value from 25.2% with ambient oxygen to a maximum of 30.6% at 23.8% of oxygen enrichment at the maximum brake mean effective pressure of 5.4 bar whereas it was 30.8% with neat diesel. The smoke, HC, and CO emissions were significantly reduced with oxygen enrichment. However, oxygen enrichment increased the NO emissions at all concentrations. Injection of water and emulsification techniques reduced the NO emissions considerably. Emulsification showed more reduction in NO emission than water injection for the same amount of water. It was concluded from the study that neat mahua oil could be effective used as fuel in compression ignition engines by combusting it under oxygen enriched condition. The optimal oxygen concentration of 23.8% could be recommended for the highest brake thermal efficiency. Injection of water at the intake manifold and emulsification techniques could solve the problem of higher NO emissions. The optimal amount of water that could be injected without affecting the engines power and brake thermal efficiency could be recommended as 4% by volume. Emulsification has the added advantage of further improvement in engine?s brake thermal efficiency.

Published: February 2019

The article presents the results of experimental studies of water droplets propagation through the sample of typical forest fuel materials: needles, leaves, and their mixture. Different conditions are considered: without any additional energy supply, with heating, in the course of intensive thermal decomposition and flaming combustion. Three methods of registration are applied: thermocouple measurements, control of the weight of the sample as a whole and of its individual layers, and high-speed video recording. Water-based compositions with special additives (bentonite, bischofite, and foaming agents) typical for forest fire extinguishing systems are used. The experiments are carried out using aerosol and single water drops, as well as a small group of the latter. It is shown that the mechanisms, conditions and characteristics of droplet propagation through the layers of needles, leaves and their mixtures differ significantly. The scientific novelty of the work is the determining of the values of all the key characteristics of these processes in the conditions of intensive pyrolysis of the material, as well as through its inert layers.

Authors: . Sulhaini
Published: February 2019

This paper aims to provide understandings on the interrelationships among risk behaviour, learning orientation and market orientation and business relationship development. This paper was developed based on a qualitative study of six British firms exporting to the Indonesian market. Data was collected through a series of in-depth interviews carried out in UK and Indonesia. The finding was established through a hermeneutic process. The exploration provides an understanding that risk behaviour, learning and market orientations are interrelated and they explain the fluctuation of relationship elements and thus the development of relationship between the British exporters and Indonesian Importers. Learning orientation has a greater role as it also influences the development through market orientation and risk behaviour. The discussion suggests that a company with a better learning orientation will have a better market orientation, become a risk taker and a better ability to develop business relationships.

Companies in Indonesia are still struggling to improve their intra- and inter-firm integration, and are still in the early stages of such integration. Therefore, this study is to measure and confirm the relation of horizontal information integration within a company's cross functional integration to vertical information integration of the company with their customers and suppliers, and how that affects customer satisfaction and financial performance. We used structural equation modeling (SEM) to investigate supplier and customer integration strategies using a sample of 90 manufacturing, distribution, and retail companies in Indonesia. The respondents from each company were limited to senior managers with functional areas of expertise and responsibility. The research was conducted through a survey questionnaire. The results of the study show 1) a positive direct relationship between integrated information and customer satisfaction, 2) a positive relationship between customer satisfaction and financial performance, and 3) a positive relationship from integrated information through to financial performance. The holistic implementation of information integration strategies in other developing countries can help companies to excel and gain measurable financial performances
